blueprint

[covert stirrup]

Maybe it's because of the loop?

Code below is the exact same as the 'M_Spline_Tool' the bottom code works, the macro doesn't

I think it's within this section that's the issue for the Macro library, I tried moving the for loop out of the macro and in construct, made no diff

[lofty hound]

Hello, im trying to use a sphere trace to determine whether character can climb right on a ledge climb, however as you can see the trace stays on a certain rotation even if the character does not. How can i get the sphere trace to stay on the right hand side of the character?

Sphere trace BP so far

[left niche]

how would the macro library know what "self" is refering to. When you use it in the pawn you get a pawn reference

[left niche]

You are adding to the Y axis, which doesn't make sense because as the character rotates his right won't be on the Y axis anymore. Multiply the right vector of your actor by that amount, add it to the location and use that

[lofty hound]

@left niche Ah that worked perfectly thanks!

[ruby surge]

Got a small question I can't find the solution to. I'm working on creating examples of the different multiplayer relevancy options. Always relevant and net cull distance are working,, but I am struggling to get " Only Relevant to Owner" working. Currently only the Server sees the door (I use door in this example) open but neither of the client sees it. So I thought, sure I need to set an owner in the door Blueprint, but I still get the same issue ;).

The interface grabs the player character

[covert stirrup]

@left niche Hey thanks for the response, where are you seeing "Self" that it would need to refer to?

oh you mean on the spline mesh component! This is also left as Target 'Self' in the working version, so what is the difference that makes one system work and the other not?

[keen bluff]

is there any reason why this would have no elements even though there's an actor on the map?

for some reason if I make a blueprint class based on the C++ class it works

but not with my C++ class

Nah it's definitely the C++ class, I didn't even have the BP class when I made the blueprint

And I'm on the same Exec Line too

anyway I guess the workaround is using the BP class instead so that's not so bad

[frank rover]

GetActorOfClass returns only the first Actor instead all of them ^-^

[left niche]

In the pawn BP self is the actor in which you are using the node. idk what self would return in a macro library. Make an input variable and input it instead of self. When you call the macro pass the self reference into macro and see if it works

[keen bluff]

perhaps I'll use that then @frank rover

I wasn't sure if it would return the right one

[keen wedge]

Anyone know why my tilemaps maybe appearing highly pixellated when the level first loads? As per the screenshot, it can take about 6 seconds before they seem to correct themselves and the display looks good again...? (level has a 15 second countdown)

[frank rover]

mipmaps 🙂

and texture streaming probably

you should make sure they are scaled right and in your texture setting choose UI and NoMipmaps ^-^ Actually I have never made a 2D game, that looks cool 🙂

however 6 seconds load time sounds like a lot

[keen wedge]

I will check those settings now... and thank you... its a bit noddy really, its a project for a Research Project I'm carrying out for accessibility devices, so very little mechanics.

GameArt2D.com for the sprites etc... TileSet/TileMap from UE4... then just me experimenting 🙂

[sand shore]

@covert stirrup this is part of the type of macros. Actor macros can assume Self is Actor. Pawn macros can assume Self is Pawn

[keen wedge]

Did you mean these settings? There's also some under "Compression" etc

[frank rover]

@keen wedge what resolution are those textures? There is a value called "Mip Bias", you can increase this, and it should load the textures faster. If you have for example a 1024x1024 texture, Mip Bias 1 will "convert it" to a 512x512 in the game.. this is quite useful for performance and packaging. For this, mipmaps must be enabled ofc

[sand shore]

You can make a macro library associated with any type. Just be careful because it cannot be used directly in the class it is based on - BP_PlayerPawn Macros can only be used with children of BP_PlayerPawn and not the class itself. This is because the assumption your macro classes are based on native types. @left niche @covert stirrup

[frank rover]

oh, texture group 2D pixels is interesting, never have seen that 😄

[keen wedge]

Not entirely sure which to change...

[frank rover]

nono, it's fine. Seems like it's allright already..

it seems strange that it loads this long for some textures.. what resolution is the texture and how many of them exist in the level?

[keen wedge]

I think it was the "no mips" etc... my screenshot was taken after I changed it following your suggestion... its working perfectly now! 🙂 Thank you sooo much...

Now I just need to work out why the HUD doesn't appear when I run the game after a build rather than in the editor... sigh...

[frank rover]

🙂

I bet you haven't configured your game mode right 😉

[keen wedge]

the texture resolution was 1024x1024. I created that in photoshop and brought all the individual images in. Unfortunately they were not all 128x128 so some fiddling on my part and I'm not using the entire area for that either, but its not really a huge focus on performance at this point 🙂

I'm not actually using the HUD setting on the GameMode, its being added as a widget via the player controller. I have the player controller notifiy the GM that the widgets are initialised (they are all hidden to start with)... the GM then does its thing and broadcasts that the game has started... the player controller then receives that message and unhides the required widgets... the HUD in this case...

working fine in the editor... no show in a separate build... have to assume its something to do with the execution order being different...

[frank rover]

sometimes adding a 0,1 sec delay can help with stuff like that. Like wait 0,1 seconds and initialize. ^_^

[keen wedge]

Yeah, I have done that in the past... it just feel so icky! That was why I started using the event dispatchers to notify other objects when they were kinda alive and ready... downside is the order really matters... I dont like either approach really..

I'll chuck that delay in now and see if it makes any difference on the build, its so frustrating to get to the end of a little project like this and then find that to be a problem... humpf...

[frank rover]

there are some other options, but given the fact that it works in editor but not in the game, I thought it was the game instance/gamemode issue...

I'm not 100% sure how Begin play for example works and when excactly it is called. If the actor is created or if all actors are created and the "loading" is finished....

if you get game mode and cast it to your game mode, you can just see if the cast fails, delay 0,1 sec and try casting again... but that is not elegant either 😄 😄

[trim matrix]

I always worry about delay nodes causing weird conflicts with interdependent bps

[keen wedge]

I do use an GI as well, but its just holding a couple of values at the moment to manage some state for which game modes to enable in the game. There's a "Practice" and a "Play" mode etc... so I turn on/off buttons on the main menu to push users through in the order I want them to go through it.

It seems like a little bit of "dark arts" with the execution order... Unity's documentation on this is fantastic, Unreal's, less so. The usual approach I take is to have every object Print something, then I can see the order... but its time consuming and painful... hehe

[frank rover]

but you have your game instance and default game mode in the project settings, right? ^^

Project -> Map & Modes

[keen wedge]

yep... well, kinda 😉

So, GI yes... default GM no.

The buttons on the main menu send game options to the level to advise as to which GM to use for each game mode etc...

Its kinda weird actually, just tried another build (without the delay yet) and the timer not only doesn't appear, but its not actually doing anything in the background... my 15 seconds practice level for example doesn't end...

gah...

[frank rover]

try setting a default game mode.. I think they are in the world settings of the level, but your level might miss the right one...

ah okay...

[keen wedge]

it doesn't in the editor - they load correctly there.. and setting a default one then takes me down the road of having to over-ride them all later...

using UE4 is very similar to sticking hot pins in my eyes 😄

I always find its what I feel should be the "simplest" thing always ends up being the "hardest" thing...

like setting your game mode and player controller, creating a main menu and then finding your character floating around behind the buttons...

[frank rover]

uhm.. how is your character spawned?

are you adding widgets to the viewport or player screen? maybe there is an issue there, because unreal spawns this play in editor pawn or whatever if there is none I suspect...

because maybe you are creating some player controller and possess the wrong one.. idk

or is the pawn prespawned sitting in the level?

[keen wedge]

This project used the 2D Side Scroller template initially, so there's a PlayStart and the GM has the PlayerCharacter set as the Pawn etc.

Again, all good in the editor... the example with the main menu and the character appearing has been an experience from other projects. Having to create separate GMs for things like a main menu and the game seemed like over kill..

[frank rover]

if not, this is probably everything I can do to solve your problem. but... you have a countdown... if that runs the widget works, right?

I am confused 😄

[keen wedge]

Sorry for confusing...

When the GM receives notification that the UI Widgets have been initialised it then calls GameStart and begins the timer... I suspect that I'm not getting the notification through to say the UI Widgets have been created, which is why then in turn the timer isn't starting....

in the packaged version.. again, in the editor.. all good... so back to execution order I think

[frank rover]

okay... and how do you send that notification? something like "get player controller"-> cast to something->notify or via an interface?

[quasi frost]

Why do I need to click this button twice to create the widget? Shouldn't it all work on the first click?

[keen wedge]

Via an event dispatcher...

[keen wedge]

Check to see if the UI has focus... your first click might be focusing the UI, then the second hitting the button. Chuck a Print node after your event, if you only see it appear once, thats probably the issue.

[frank rover]

ookay... not sure if remove from parent should be called immediatly (could be a cause, but not sure) ..I think you need to print some stuff in dev mode and see where the problem is excactly x)

[quasi frost]

This is how it is created

[keen wedge]

Yeah, doing that now, just added a tonne of Print nodes... sigh... thanks for the suggestions, appreciate the help 🙂

[keen wedge]

Your variable setting is for something other than the widget reference... the widget reference wired up to focus is probably null at that point.

[keen wedge]

Try the Print node suggestion, see how many times you get the Print message appear..

[quasi frost]

Oh duh lol

thanks lol

[keen wedge]

🙂

[quasi frost]

Mm even fixing that still doesn't fix the double click issue. Let me setup the print nodes

[quasi frost]

So it doesn't seem to flow to the continue event for some reason on first click even though the bind is being called

[frank rover]

does the found account event exist? can you even bind to your own (self) events? never did that ^^

[last abyss]

because ur binding the event after you're calling the event?

[keen wedge]

It probably doesn't make much difference, but I tend to wrap my Binds up with a CreateEvent and then point them to a function. I'm not sure I've ever tried the binds like this - not saying its wrong, just different from my approach.

[frank rover]

HAHA

YEEES

omg 😄

[keen wedge]

I normally have two functions from BeginPlay, SetReferences and BindToEvents

[frank rover]

problem solved 😮

[keen wedge]

I get all that stuff done the beginning.

[quasi frost]

Instead of a bind I could do a wait for function call and turn account data into a function I suppose.

In the future that event will be pulling data from a database

[last abyss]

you are binding the event, you're not calling it to be ran. so first time it runs get account data and then binds the event continue login to 'Found Account'.

so it's only natural that you have to click twice before it actually runs continue login in this case

[keen wedge]

So, my issue does appear to be related to the event order....

Two screenshots, one after packaging and running as an application in Windows, the other running the game in the editor...

PC = Player Controller
GM = GameMode

Interesting, in the windows build, the GM doesn't even trigger the Construction script... but whats interesting, and annoying, is that the GM is begin run after the PC... which is why my stuffs all broken... curses...

[maiden wadi]

About the gm combative script, it may not print because the printing system already exists in the editor when gm is created. In package the gm is probably created before it can even get a reference to the debug stuff to print.

[keen wedge]

Thanks, that's handy to know...

I have kinda got around this at the moment by having the GM now call a dispatcher which the PC binds too that says "Hey, I'm awake now"... after which all other business can carry on... it seems to be working but has made a mess of my nodes... lol... hate it when that happens! 🙂 I feel that this is "safer" than just arbitrarily dropping in a 0.2 second delay... I feel uncomfortable with that as an approach, despite it seemingly working in all cases...

[maiden wadi]

As to the begin play stuff, you cannot rely on begin play order at game start, gm will call that on all current actors. Usually this is in order for testing because of things loading the same way each time but it is bad practise to rely on begin play order. It's never promised.

[keen wedge]

Would prefer an overriding "Pre-Warm" setting personally, something you just set in the options that says "Wait for 0.2 seconds" - after which ever thing is guaranteed to be ready to use...

[maiden wadi]

That's one leading cause to long load screens in games. To many timers waiting for other stuff to be ready. I find it better to just make registering events. If two things need to know about each other and need both ready, make both of them try to get each other, one will fail since its created first. The second will succeed. You can make them update each other when the second one is valid. At that point you know they're both valid. Also be careful with begin play if you're doing multi player. It will get called every time that actor becomes relevant and spawns on a client, not just when the server creates it.

[keen wedge]

hmm... I'd hadn't thought of that, probably because most of the stuff I make is kinda small, so I never really encounter those issues, just EVERY-OTHER-ISSUE 😄

That suggestion about making them let each other know - I don't suppose you have a little bit of BP you could copy/paste as an example for that do you? I think I've got half of that in place now with the dispatchers etc, but there isn't anything really checking to see if it exists and looping around until it does... that kinda loop terrifies me, as if I screw something up it'll just be endlessly going around in circles for eternity... I suspect you have something for that too... any info is appreciated... and thanks for the replies 🙂

[maiden wadi]

I don't at the moment. On my phone. I'll be home within the hour though. Timers are a bit dirty, but they can work for that sometimes.

[keen wedge]

No worries, but if you find a spare moment I'd be grateful. Thanks again for the replies 🙂

[dawn gazelle]

🤔

I was just trying to change a variable type and this happened o_o

[maiden wadi]

@keen wedge So in your case, you need stuff to happen relating to GameMode and a PlayerController, but you need it to happen in GameMode first, and then the PlayerController?

[keen wedge]

The player controller, in this scenario, creates UI widgets, adds them to the viewport, but hides them.... it notifies the game mode that the ui has been initialised... the game mode does some other bits and then reports out (dispatcher) that the game has now started. Upon receiving that, the player controller then unhides the appropriate ui widget. Other items do other things based on that same game started announcement.

Since messaging in here today and going down this road, I have subsequently added another dispatcher and binding, and removed the items that were happening in BeginPlay in the controller, leaving only the binding to this new dispatcher. Upon receiving the "Initialised" message from the game mode, a function is called which then runs through all of the steps that were initially in the BeginPlay within the player controller. Its working, but does mean I have kinda two Binding functions now which is a bit erksome... but I supposed I have to get over that as no one other than me will ever see it.

I have a second game mode also, so will need to add this to the other one too so that they both work in the same manner.

[maiden wadi]

On the GameMode note, why not subclass the native GameMode type you're using, and then reparent both of your game modes to that and then use that for this logic. Then stuff can cast to that instead for this stuff. Alternatively, you could do it in an interface, but that means repeating all of the logic in both classes.

[keen wedge]

I did consider the interface approach yesterday, I was running into other problems where I needed to effectively call the same function but have it perform different actions. The whole project went from kinda working, to kinda completely screwed and I was so tired I couldn't see a way through it. In the end I duplicating game modes and controllers, specifying a controller for each of the game mode blueprints and had the two different game modes (which I wanted anyway).

They are both using a base class, which is when I'm running the Initialised dispatcher from, so at least something is shared. I find trying to do anything with inheritance, delegates or interfaces really challenging via Blueprint. I don't know C++, only dabbled a few times before... come from a C# background - much preferred being able to actually "read" my code instead of all these nodes and stuff... but there we go... grumble over...

Because I'm up against it time wise for this project, I think I'll have to just duplicate this current approach which appears to be working, at least for now. This is part of a research project into accessibility devices and the Unreal project was only supposed to be a small part of that really... lol.. getting bogged a lot in it now, what with tilemaps having flickery lines, execution order woes and so on... all I want is this little dinosaur to run and jump around these little platforms... always feel I'm asking for the moon a stick! 😄

[maiden wadi]

Haha. I'm so backwards. I can write C++ easily, but I dislike reading it. Most of my functions are just blueprint functions rewritten into C++ for better performance.

[keen wedge]

hehe, sounds like if we swapped out half of each of our brains we'd make a whole! 😄

What's really annoying about this problem is having now resolved it for the packaged version, running it in the editor now longer shows the UI or the timer... ffs... round I go...

I shouldn't be this hard...

[night quail]

Hello everyone, I'm having an issue where my mouse event stopped working (after making a bunch of minor changes) and I'm not sure what's wrong... oddly enough, if I add my blueprint to another level (like the Content Examples levels), everything works as intended. In addition, my TraceLineByChannel node also stopped registering hits, even though actors are well within the InteractionDistance. Does anyone have any idea what could be the issue?

Edit: something more seems to be happening when I add it to another level, because it still isn't registering any hits, yet somehow it's still working as intended.... (I've added a fluid sim blueprint so that when I click the mouse it causes ripples, and the level I mentioned earlier is the BlueprintRenderToTarget content example map)

I made sure to use the same Game Mode for each level

[maiden wadi]

@keen wedge For your earlier Beginplay issue with multiple actors needing to be valid and ready to call stuff in order.

With multiple actors, it's fairly easy to turn that check into an array of objects and create a small checking function on the array. Not the most performant, but it's a linchpin function that only needs ran rarely.

[keen wedge]

Thanks for the above, kinda similar to what I have, but in that bottom screenshot you mentioned about now checking whether the player controller is valid. Where is that check though? All I see is a function being called, which it may not etc.. am I missing something?

[maiden wadi]

The cast does that. Casting will attempt to cast the object input to a different pointer type. If either the object is not that type, or the object itself is invalid to begin with, the cast fails.

[keen wedge]

Ah, ok, so thats the dead end then - but isn't that what I kinda have now, e.g. the dead end, so what makes it try again? Not sure about the "Stuff to call on Each" bit in the player controller etc?

Oh I see... the PC calls the same function that the GM calls... so it could be called twice, or maybe just once, DoOnce thing locks some of it down etc..

[maiden wadi]

What happens in logical order is that one beginplay runs. Lets say the GameModes's runs first. If the controller is already valid at this point, it will pass the do once and do the logic needed. If the controller is not valid, it won't pass the cast so won't run the do once or the logic after. Then comes the controller at a later time. The controller calls the same function. If it's already been ran the DoOnce stops it from running twice. If the Controller was invalid on the game mode's run, this will run it again now that the controller is valid. One way or the other as long as you're using the correct classes for the casts, the logic will get run at some point once both actors are valid.

[keen wedge]

Yeah, thanks, I get it now... ta for the explanation though.

I'm sure this would work, but the one bit which still feels "icky" is that I "know" its going to fail, which means having it run through the code is effectively creating a delay, so that the second time it runs through, it works. Being that we are just creating a delay, the Delay node with the 0.2 default (which worked earlier annoyingly!) would seem easier to read. But I am LOATHED to do that...

This stuff always leaves me feeling like I am massively not understanding something because, again, it shouldn't be this difficult should it? In your projects, do you have to consider and apply this kind of approach each time?

[maiden wadi]

Personally, if I was doing this, I would have just made a custom event in the GameMode. Then made the Controller's Beginplay do it's own UI stuff and then call the GameMode to do it's stuff. GameMode will always be ready and alive before a Controller even if the GameMode's Beginplay is ran after the controller's. GameMode creates the controllers.

[keen wedge]

Even with the custom event in the GameMode though, you'd still have the reliance on knowing when the PCs stuff was done? In this case, I need to make a UI widget visible when the game mode is ready... so the GM needs to know the UI widgets are are ready before it can say "show one" etc..

[maiden wadi]

It all runs on the same execution line in order. So for instance..

[dense badger]

Anyone here know how I can capture what actors are overlapping a box in the editor inside a construction script? The function I made works correctly at runtime but fails when called in the editor on construct.

[keen wedge]

I think one thing I've been trying to do was use the event dispatchers instead of making those direct calls as you have at the end of the first screenshot. Probably trying to make stuff event driven but I'm assuming getting it wrong along the way... I was trying to keep each object only really concerned with itself and not much else, something that seems almost impossible in blueprint... again, I probably lack the experience with Unreal to do it properly. 😦

[dawn gazelle]

I'm fairly certain this is not possible as collisions are not simulated in the editor. Eg. You can place two objects on top of one another that would normally collide.

[dense badger]

This is overlap not collision

It definitely does "something" but it's really wildly unpredictable

Some actors seem to return overlaps and others just whiff

[maiden wadi]

It's very easy to do in blueprint, but it requires some really abstract work. In your case where you're trying to do some very specific stuff in order, it's more difficult to stay abstract.

[dense badger]

Strangely in a super simple test case I can get an overlap in the editor but the overlap doesn't "align" to the volume VS the object it's like the transforms are borked. But in game, works perfectly

[keen wedge]

This is a "massive" ask, but I don't suppose I could ping you a zip of the project and you could let me know where my approach is perhaps not so great? The project isn't particularly bit, and its documented. I'd be keen to hear your thoughts. Again, massive ask and I fully appreciate you may not have the time so not a problem if not.

[dawn gazelle]

What are you using in the constructions script to get the overlapping actors?

[night quail]

I realized I accidentally shortened the line trace distance, and easily solved that issue, however the lack of mouse click registering is still causing issues... execution never reaches here (and it used to before):

[unkempt quarry]

I'm trying to generate multiple tiles with the tile generator UE4 showcased on a livestream, but I can only get it to generate two different types of tiles, if i try three or more, it breaks. Any suggestions?

[maiden wadi]

I don't know how C# handles stuff, but at least in C++, you can't really do anything without some sort of reference. Class inheritance is extremely important for this reason. EventDispatchers need a casted pointer to bind from or call from. Interfaces still need a basic object type, etc. It just comes down to how you want stuff to communicate. An Event Dispatcher is nothing more than a list of references to tell that something happened when it's called.

But yeah, I could glance through it.

Anything to procrastinate finishing this inventory.

[dense badger]

@dawn gazelle

[keen wedge]

Thank you so much, what's the best way to share it? Not sure if I can attach it here? I'll also take out these last couple of changes to try to make it work properly when it runs on its own, I'm just going back and forth, either working on its own or in the editor... never both... sigh..

[maiden wadi]

Not sure. What engine version is it on?

[keen wedge]

4.25.3

I can zip and upload to my website and share it from there if thats easier...

[maiden wadi]

That works.

[keen wedge]

okey dokey... will do that now... I would remove the Start Content too but as I based this from the 2D side scroller template there might be some references in there and I dont want to break it further at the moment... apologies if the download is a chunky one..

[maiden wadi]

I play ARK. Large file sizes don't really surprise me much. 😄

[keen wedge]

I've stripped out the folders that can be rebuilt when you open the project (saved, intermediate, builds etc etc), down to 625Mb, uploading now...

[dawn gazelle]

Interesting, ok, so yeah on my end that overlap components node does work while in editor. Learn something new every day.

What's probably happening is that the actors you're trying to overlap with aren't using the collision profiles that you're looking for or do not generate overlaps with the connectionvolume's profile?

I was able to get consistent overlaps on some pawns I had placed around that for sure have the right profile.

[maiden wadi]

@unkempt quarry How are you trying more? It looks like your branch there should possibly be a Switch On Enum or Int.

[dawn gazelle]

Though I am on 4.26 -_-;;

[unkempt quarry]

I tried multiple branches

[dense badger]

@dawn gazelle I don't believe it's collision profile related, as I said I get overlaps at runtime as expected. And I get strange overlaps in editor, IE: They overlap but don't appear to respect the bounds of the object OR the box, it seems to have something to do with using the box collider... it's like it's extent is completely ignored in the editor

@dawn gazelle If I set it to default extents it seems to work as expected in the editor, going to try replacing it with a static mesh cube instead

[unkempt quarry]

Switch on int works fine, thank you @maiden wadi

[dawn gazelle]

Yes alright, I'm experiencing the same now after mucking with the scale of the collider.

[dense badger]

@dawn gazelle It's like the collider box isn't initialized yet somehow... I wonder if I set the extents in the construction script if it would work...

@dawn gazelle Yep totally works if you hard set the extents in the construction script

[limber finch]

Can someone help me out 😅

My character rotates with with mouse, and I'm trying to make it so the when the character is rotating, an idle rotation animation plays, but when the character stops rotating, it switches back to the standard idle animation. Any ideas?

[dawn gazelle]

So i believe here what may be happening is that it's only using the default objects in the editor. It doesn't take into account what you may have set within the editor.

I had a similar problem yesterday where I was trying to make a text renderer with some data that is added in the editor on a component - it wouldn't return any values. When I set the values on the component in the blueprint, it would return the values set.

[dense badger]

@dawn gazelle That makes sense, I suspect the construction script is getting called ahead of those actor properties being set.

[dull tree]

On every player is working but guy which died have overlapping every child

[dense badger]

@dawn gazelle Thanks so much dude! Appreciate your help walking through it! 🦆

[dawn gazelle]

Glad to. And I learned something new too 😄

[thorn ermine]

you could play a montage that loops when it detects you are rotating, and simply stop the montage once your are done, you can call this on the animbp.

[keen wedge]

Pinged you a PM as have limted bandwidth on the site. Not chasing, but conscious I suddenly switched form chatting here to the PM etc... I've only started using Discord again in the last few days so I'm trying to find my way around it etc 🙂

[maiden wadi]

Yeah, started it. Should be done in 17-65 minutes. Haha, jumpy upload.

@dull tree Rather than making the server get all player controllers to loop over them to do this in each one with a client RPC, why not just make an RPC in GameState? Make the server multicast to all clients the latest kill feed and have the client's version of the Gamestate call the update in the local UI. Then it's one actor handling the replication for all and it should be consistent.

You also should not be letting the client dictate the kill feed with a Server RPC. Server should be the one determining death with it's own variables. So it should handle RPCing the kill feed itself rather than a client updating it.

[keen wedge]

hmmm, that may assist me in cancelling my hosting then! lol...it uploaded at a shoddy 1.7Mb p/s... ooof... just assumed that was my end and that the download would be better..

Wow... and I pay good money for this hosting service too... hmmm... will re-think that too then... WinHosts... 😦

[keen wedge]

I could chuck it on Google Drive or something... although, I dont typically share stuff on that so not 100% sure how to..

[limber finch]

How can I achieve this in the AnimBP? As far as detecting if I'm rotating?

[summer bolt]

anyone know why this cook is failing

[maiden wadi]

I'm using runtime audio importer to playback wav files - they are exported in order but due to the transcoding, they don't all transcode in the same order (like if you started transcoding 1 first and it was long, transcoding #2 would finish and it would fire this bind event that adds it to that SoundWav Array

[summer bolt]

Not sure where to post that but im cooking bps soo

[thorn ermine]

when you rotate with your mouse, that event you could use to indicate to the animbp you are rotating using a variable for example, the animbp can check if the rotation montage is already playing, and if its not play it

[limber finch]

I guess I'm having trouble finding out which event is calling my rotation with my mouse, trying to print string on each event input and it doesn't seem to be working

[maiden wadi]

@summer bolt This is your actual error. Something is using a null reference pertaining to the HelicopterBP. Usual fixes seem to be doing a full content browswer FixUpRedirectors, and also going through each blueprint that may use this asset or class and recompiling them or switching the value to something else, compiling and then back and compiling again.

[summer bolt]

@maiden wadi When i try click on the bp i crash?

[thorn ermine]

it should be something like Turn, or TurnAtRate, then you can set a variable there like YawInput or something
Then in animbp, you could use a blend state if yawinput != 0 and speed close to 0, or play anim montage

[maiden wadi]

@summer bolt Were you doing anything in the Construction Script?

[summer bolt]

Dont think so

[maiden wadi]

Odd. Dunno then. If the Fix up doesn't work, your only real choice is source control. If you're lucky you have a recent save of the class in the ProjectDirectory\Saved\Backup folder. You can copy it into your ProjectDirectory\Content folder, whereever the corrupted one is.

I solved my issue by adding the following nodes at the BeginPlay event in my bp, but I've never had to do that before to get buttons working... given this solution, does anyone have an idea as to what changed?

[keen wedge]

I don't think there's an "easy" way within Blueprint... I've looked for some things like this myself in the past. A quick search just now pointed me to this;
https://www.unrealengine.com/marketplace/en-US/product/low-entry-extended-standard-library

Its free and might be of use to you... if those paths/names are accessible (GetDisplayName?) then you might be able to re-order that way. Might be problematic depending on the name when you have things like 1, 11, 2 etc...

[open crypt]

I have that....let me see if there is something there...thanks I appreciate it

[keen wedge]

No worries, I've not used it so can't be of much help there, but on the store there page shows a load of the functions it provides out of the box are there are quite a few for sorting arrays.. no idea how performant it is either..

[true valve]

So I've a SK mesh and added a child mask SK mesh. In const. script, Added master pose component. Unfortunately the mask won't sync.

[dull tree]

it should looks like that?

[grizzled marsh]

Hi all - ultra noob question here:

[maiden wadi]

@dull tree Not quite. I assume you're trying to make a typical shooter kill reel for when a player is killed?

[dull tree]

yeah

simple

nick and nick

[maiden wadi]

@grizzled marsh Put this into a function and return if it's true. If the function finishes and the traces and the sphere thing and none hit anything it'll return false. If any trace hits something, it can return true and break the function there, stopping you from potentially doing many unnecessary line traces in the process.

@dull tree So, if a player has died on the server. The server just needs to get it's own game state and call this Multicast RPC with the correct inputs. Now the logic will be on each client. So now you just need to get the location of your kill reel widget, and call an update to the kill reel with the names.

[dull tree]

get own game state u mean cast to gamestate yeah?

[keen wedge]

@maiden wadi any luck with the download? I've just tried implementing the "Stuff to Call On Each" suggestion you had above, but the result is the same, actually, not quite the same, now I dont get the widgets appearing or the timer starting in the editor or a standalone package... lol... 😫

[quasi frost]

I am following a guide on making a login for ue4 using VaRest. When I get to this part (youtube on right) I can't find this function. All I can find is what you see on the left, however even if I wanted to use that I am not sure what to target. Anyone know either what I should use here instead or what to target for the slightly different json request that I see?

[keen wedge]

I dont know anything about the stuff your doing, but the blue function node on the left image isn't connected to anything... so if the error regarding target is related to the node with the red warning on it, that's probably why... its the same as having nothing connected to it...

[quasi frost]

Yeah I know that lol.

Gonna try this for now, see if that works

[keen wedge]

Whats the date on your tutorial?

[maiden wadi]

@keen wedge Been looking through it a bit. I like it. But I admit you have a very roundabout way of doing some things. For instance the controller movement. Normally I'd recommend putting any sort of character controls in the character itself, but it's a non issue in simpler projects, just that if you ever had different types of characters, you'd need their controls to differ. But the control rotation part. You can get rid of tick and do the rotating all in the axis event. This for instance allows you to get rid of an extra function call on tick, and remove a couple helper functions and keep the same functionality.

[keen wedge]

Alas that was inherited from the 2D Side Scroller template... ironically it was on the Character initially, but I was under the impression that the "controller" was the object that was supposed to "control" the character etc? (dont mean that cheekily), but I thought that was intended to take the inputs and then feed the character? I wasn't liking the Tick stuff... but when I took it out I noted that the animations changed, from either not ending properly, or not facing the right direction, was easier to just leave it in.

I'll take a look-see at the above (thanks) and see about implementing it, but its really this other issue that is causing me the biggest problem at the moment.

I applied your approach a second time and worked through it again - I have it working now, both in the editor AND as a standalone package, - BUT - the order of the "Stuff Player Controller Needs To Do" and "Stuff Game Mode Needs to Do" in your example/screenshot matters... if I do the controller first... it doesnt work at all... the controller has to be last...

[maiden wadi]

One other note is the references everywhere. This isn't so bad in some cases, but a lot of the references you're saving are very easy to get and are not performant heavy to get either. GameInstance, GameMode, GameState, PlayerController, PlayerPawn/Character, all of these are very quick calls and can be used pretty much everywhere in either client side only code or single player. Saving them also creates more effort for you, since you need to follow along and update them when they're not valid anymore if say you kill off a character, destroy it and spawn a new one. GetPlayerCharacter works already, but an old saved reference needs updated. I'm a huge fan of less upkeep in coding. And this note is highly personal preference, but for those easy to get instances like that, I wouldn't personally bother ever saving references.

[keen wedge]

Thanks interesting to know, thanks. I'd assumed that by grabbing the reference to stashing it I wouldn't need to keep making calls to get it... and for my own sanity it meant just dragging across one variable node instead of having to have two everytime and casting it etc... I was under the impression that the Cast was the expensive part and that was to be limited/avoided where-ever possible.

[dull tree]

@maiden wadi
get own game state u mean cast to gamestate yeah?

[faint pasture]

That's not what casting is

[dull tree]

Still doesnt work

[faint pasture]

You are not doing that from a server instance of whatever actor all that blueprint is on.

[dull tree]

this is from event any damage so its should be on sserver

in main character bp

[faint pasture]

@dull tree start from the beginning, what exactly do you want to have happen when a player character is killed? do you want everybody to see the kill feed or just the victim or whatever?

[dull tree]

everyone

[faint pasture]

Do you already have some event that happens when a character is killed on the server?

[dull tree]

and its working for everybody without dead guy

on player blueprint? yeah

[pine trellis]

im getting this error where would you place an isvalid?

[faint pasture]

@dull tree it's pretty weird to have the function that shows the kill feed be on the character but whatever. Do this when a character dies ON THE SERVER.

1. Get all player-possessed characters.
2. Run on owning client the Show Kill Feed event.

That's it.

That's a bad design tho, show kill feed should be on GameState probably.

[dull tree]

i had that on gamestate but it doesnt work and i followed some tutorials and now i am here

[faint pasture]

It works, you just aren't doing it right.

With the game state approach, you would just get the game state, and then multicast show kill feed.

[dull tree]

so

on player i should have event that is calling gamestate to show kill feed?

[faint pasture]

On the player character, yes. And you should check is authority before it if you don't have one already when doing the On Killed stuff

It can be earlier like in your damage handling

But you need some way to know whether you are on the server instance of the character or not

[dull tree]

i got this on event any damage

[faint pasture]

K so if you know that anything after that is only running on the server, then you're good. Just get Gamestate and cast it to your custom Gamestate and call multicast Show Kill Feed.

[dull tree]

got this on gamestate

[keen wedge]

Just plugged in that suggestion for removing the Tick call... thanks for that, works a treat. 🙂

[dawn gazelle]

Your M_ShowKillFeed event is a multicast event (Executes On All == Multicast) .

Multicast means you're sending it to every player already. You don't need to get all actors of class, and loop through them and send another replicated event (the C Show Kill Feed).

You want to feed the Killer and Death values to your widget.

[unkempt quarry]

I am trying to randomise the rotation of the tiles to make it less grid like but I have ended up making islands instead, this is probably really wrong but any suggestions?

[faint pasture]

@unkempt quarry what do you mean randomized rotation of tiles? don't you only have like four orientations that make sense? Or are you meeting randomizing the rotation of the things inside of a tile

[dull tree]

So just C show kill feed on gamestate and Player Ref yes?

i mean plug player ref to target

[cursive girder]

Any idea what Im doing wrong here. I've got a material with some parameters, one of which is a texture. I do a SceneCapture2D and try to plum it into the Material, which then renders into a widget, but from what I can see either the widget isnt using the material, or the parameter isnt getting applied.

[faint pasture]

You don't need any of that. You need to implement the stuff that shows the actual widget on the local player in that event. Literally just multicast event show kill feed and then show the widget on the local players viewport

[dull tree]

right?

[faint pasture]

@dull tree no, take all the logic that shows the widget and put it in place of that function that you are calling on the player actor. The player actor doesn't need to do anything besides notify the game state that it died

[dull tree]

ooooo ok

[keen wedge]

This for a mini map? When I made one of these I needed to use a RenderTarget in the process.

[cursive girder]

Yeah, its a minimap

It worked up until I tried to inject a scenecapture.

[faint pasture]

@cursive girder is your scene capture 2D writing to a render Target

[cursive girder]

thats spawning and capturing. Am I doing it right?

[faint pasture]

@dull tree take all of your UI off of the player character.

there's like three ways to do what you're trying to do and you're taking bits and pieces of all three and mashing them together. It's a total cluster lol

[dull tree]

3 is better then 1 😛

[dull tree]

i am lost 😦

[cursive girder]

0.3 + 0.3 + 0.3 = 0.9 😉

[keen wedge]

You way is a little different to mine. I had a camera positioned above the FirstPersonCharacter. I had the TextureTarget set to MiniMapRenderTarger (a RenderTarget I had created). Then I right-clicked on the MiniMapRenderTarget in the Content Browser and chose CreateMaterial. The Material was then used in the UI widget.

[unkempt quarry]

Sorry, I wasn't specific. Randomise between 90, 180 and 270degrees

[cursive girder]

@keen wedge Wouldnt that be the equivalent of a topdown camera?

[keen wedge]

Yeah... I was just experimenting... but I figured the RenderTarget bit was maybe what you needed?

[cursive girder]

It is a render target 😦

[keen wedge]

The other issue I found was that it rendered lots of things I realised I didn't really want. Shadows and stuff... when things moved in the world they moved on the map...

[cursive girder]

yeah, mine is a scene capture for that reason

You can exclude stuff

and I can do fog of war once I got this working.

[keen wedge]

Wish I'd done that... but I was experimenting/learning etc... what I learnt was my approach was crap 😄

[cursive girder]

but like I said I cant seem to get the texture into my material 🙂

[keen wedge]

Was trying to create something similar to Fortnite etc..

[cursive girder]

or I cant get the material onto my widget.

[keen wedge]

The manual way is the right-click "Create Material" thing... can you do that from nodes?

[cursive girder]

Chances are fortnite are doing something similar to mine

[keen wedge]

(yeah, think so... they have the writing and stuff all over it, more like an image with a cursor on top perhaps than what I did... still, I learnt.. 🙂 )

[cursive girder]

Isnt my Create Dynamic Material Instance doing what you suggest?

[keen wedge]

Could be... getting out of my depth now... sorry...

I note you're getting the MapTextureParameterName but then not feeding that in, instead have a text reference? Maybe not related?

[cursive girder]

I disconnected it and hardcoded it

I was trying to write this thing as a plugin, so it was a parameter on the widget

[keen wedge]

Ah... is it worth testing the creation of the material manually from the RenderTarget and setting it manually to see if that works first?

[maiden wadi]

@keen wedge Blob of text alert. Avoiding casting is kind of a misconstrued issue in unreal. Casting itself costs nothing. It's just changing a pointer type from one to another and then checking if it's valid. The valid check takes a bit, but it's extremely cheap. It takes hundreds of thousands of them in a single instant to make a blip. It's also cheaper than using an invalid pointer since that will be 12.7X slower in bp and will crash if done in C++. The real serious cost of casting is encapsulation. When you cast to something, this means that object needs to be loaded when the object casting to it is loaded. This means that for small games, you can cast to everything and you won't notice anything. But much larger games, you'll end up with the whole game in memory at one point. The reason this happens is because Unreal loads up a default version of each necessary actor that something might need and stores it in memory in case something needs it like spawning a new actor, or other stuff. So if you have Object A that gets loaded, and it casts to Object B anywhere in it's code, not just things being executed but any sort of hard pointers be they casts, or variables, etc, Object B will get loaded. If Object B casts to or has a hard pointer of Object C, then when Object A gets loaded, Object B and C get loaded. This starts a chain reaction that doesn't stop until everything necessary to reach is in memory before Object A is actually loaded up. So if you have a character on map 1, and a boss on map2, and you have an ability in character that casts to that boss, that boss gets loaded even on map 1, even though it's not used until map 2. In small projects, this doesn't matter. In large projects, this can quickly get out of control without proper use of class inheritance to cast to lower level emptier classes and interfaces, and use of SoftObjectPointers.

[cursive girder]

so manually add the scene capture, create the texture and plug that into my minimap?

and turn off the blueprint stuff for now to check it works?

[keen wedge]

I was thinking mainly from the texture creation point if you can, and then plug that directly into the UI... could perhaps leave the scene capture stuff in... was just a thought... trying to break it down/simplify it a bit etc... might help point to the issue..

[keen wedge]

Thanks for this @maiden wadi , I could really do with a massive learning class on all this stuff... only started fiddling with Unreal about a year and a half a go. Had a Unity background before, for a few years, but again kinda hobbyist...

Where exactly does one garner all this info from, because generally, the UE4 documentation is somewhat lacking in my experience....

[cursive girder]

I found the cause! 😩

if (MiniMapVolume != NULL && MiniMapVolume->MapTexture != NULL) {

    // Set up a MapTexture, and connect the update function to it, then tell it to update.

My code always pulls the texture out of my minimap bounding volume

next problem. Its expecting a UMaterial* and I've currently got a RenderTarget texture. How to map from one to the other....

[keen wedge]

Congrats on finding the problem! Progress at least...

That "Create Material" thing I was on about I think is that next part isn't it? I didn't really understand the stuff you had about the Create Dynamic Material Instance, again, out of my league a bit there...

Does the output RenderTarget texture not have a "CreateMaterial" function or anything like that? Or is there a standard "Create Material" function that you can then push the texture into? (sorry if this is what you already have..)

[cursive girder]

It has a create material, but apparently that material doesnt fit onto a UMaterial*

[keen wedge]

What "type" does it create?

[cursive girder]

This is the fun of mixing c++ and BP I guess

[keen wedge]

I'll be sure to avoid it 😄

(when I learn some C++)

[cursive girder]

It creates a "Material" type

[keen wedge]

hmmm.... I've never really understood all the letter prefixes Unreal uses in front of the API stuff... UProperties and all the rest... anyway to convert it?

[cursive girder]

Trying to figure that out now

Ha!

Oh that is awesome and sucks at the same time

[keen wedge]

Dont suppose this is of any use? Has some stuff about UMaterials...
https://isaratech.com/ue4-programmatically-create-a-new-material-and-inner-nodes/

[cursive girder]

Its not a umaterial, what its doing -

its taking my comments and adding them as helper hovers

I commented out the Umaterial, and it spotted it as a helper message 😄

Still got the same problem though....

Convert my rendertargt to a UTexture2D...

[maiden wadi]

@keen wedge I dunno. Honestly I've learned a lot here in this Discord and from a lot of personal testing projects. I've only been messing with Unreal for just over a year now. I tried Unity and Cryengine and nothing really clicked. Unreal just makes sense to me by comparison. 🤷‍♂️ But the docs aren't bad, but they're old and outdated. There's still a lot of relevant info. The Docs and Livestreams can be nice sometimes, but even they can teach bad practice funny enough. They're kind of like college level stuff from what I've seen of college students in here. It's dumbed down and over simplified to the point that it's not really world usable and only meant for helping understanding. Like dumping all of your game logic into your level blueprint because you don't want to bother teaching your students about object oriented programming. My biggest suggestion is watch the discord often. Glance over conversations and follow them if it's something you sort of understand. A few big names to follow when they're helping people is Jambax, UKaos, Zlo, Stranger and eXi. They're usually pretty informative, even more so if you end up in Multiplayer stuff.

[cursive girder]

Well, Im done for the night. Its progress at least, thanks for being a sounding board Rob 🙂

[keen wedge]

Many thanks @maiden wadi , ironically I am currently studying game development at uni, which is where my Unreal "experience" is coming from... its not being taught in an OO way thats for certain, that was the background I had previous in software development and I'm struggling to find ways to do that with BP... its just not "clear" to me with all the nodes... I'd rather just see code... but as mentioned earlier, have little to no C++ experience... maybe that should be one of my next focuses...

My comment regarding the docs I suppose was in comparison to Unity's. One of the things I always appreciated was that there were typically usage examples. I don't tend to find that with UE4's documentation... often those little examples were a great starting point to move forward from. Ironically I just went searching for a "bad example" and wasn't able to find one... lol... ironic how its only when I need the bloody help I can't find it! 😄

If you're doing a dedicated server, Execute On All executes on the server as well, and the server does not get a HUD to add widgets to. You can do a "Is Dedicated Server" branch test at the start of the multicasts and only proceed on the false so that the server doesn't run it.

if I were to move my blueprint the endpoint stutters its position, so I wonder if there is a better way to do it

[dawn gazelle]

UI Widget Central HUD

[grand oasis]

drag out the target pin and see what you can attach it to

promote it to a variable and then set the variable

I assume the widget target would be whatever thing you're using to draw it on screen

[dawn gazelle]

So the target has to be an object of the class of your UI Widget Central HUD as that's where the function exists. I believe the trouble is with the implementation of how you're trying to use these features.

I'm not familiar with the painting thing myself, otherwise I'd direct you better :/

Hello everyone! I've been inspired by Valheim and want to try messing with procedural terrain generation in Unreal. Does anyone know any good resources for that? I've looked at how to do it with a material, but that makes me wonder how I could read, for example, the biome at a certain location via Blueprint for asset placement and such.

[north oriole]

C++ components inherited in BP cant be attached to a component. Is it possible to reparent the Character class mesh to a Scene Component?

Or do I have to make my own character class

Or do I have to just ignore the Character class mesh component and add more in the child?

[sand shore]

@north oriole You cant do any of that

You could make some pawn that isn't a character but does a lot of the same things... that'd be tough.

the problem is that most movement components assume the root primitive needs to be swept during moves, as opposed to another set of components.

there are other reasons why you have to use that mesh component.

in short, trying to hack around Character to do things a weird way is likely to be painful

[uncut lark]

Anyone have any sources for learning how blue prints work?

Is there a way to set an input ReleasedKey event, so that it is still listening for that ReleaseKey event, even after the input is lost?

I have an application where I am using a 2nd screen (Spectator screen) to score the VR Player. It is setup to immediately return input back to the VR player, but when it takes it, any logic tied to the Press/hold & Release, is interrupted -

I tried setting up some logic to prevent the event tied to the ReleaseKey button (when it gets unintentionally triggered when the BP loses input for a split second) but the problem is, when input is restored back to that same BP, the ReleaseKey will never fire, because the system has recorded that it already has, even if it really hasn't.

If I could initiate an event from that spectator screen TO that blueprint that basically said, "Okay, flag this button as pressed now" so the system would start listening again for that OnRelease, then I think I could make this work.

@jaunty stirrup I'm uncertain if that node uses Relative of the component being input or relative as in actor relative space, but I'm going to assume that it's relative to the component's hierarchy... so. If that's the case, you need to inverse transform the world location of the camera you want to move to, into the relative space of the moving camera's attached parent. For example, this following image should work if that assumption is correct.

[summer bolt]

uh ok

[jaunty stirrup]

@maiden wadi Thanks a lot a try this

[summer bolt]

anyway i can fix this camrea

Still dont get it sorry if im a bit dumb

any 1?

[hollow cape]

you have the spring arm root at the midpoint of the skeletal mesh. When you are scaling the mesh, I'm assuming you aren't moving the camera back. You should probably change the root (pivot point) of the spring arm, and also when you scale the mesh you should probably scale the spring arm length as well @summer bolt

[hidden flume]

Hi, guys, how would i play my custom animation from a function inside of State Machine?

[summer bolt]

gotcha

[dull tree]

i am making leaderboard on click so when u press TAB it creates LeaderBoard

it works great but when i add childs it dropsfrom 120 fps to 4

with att add child node it works smoothly

any idea why?

[maiden wadi]

@dull tree Does the WCHPlayerSlotWidget have any OnConstruct logic in it? It sounds like either an event running when it gets added to screen, or some crazy weird issue with the slate being drawn to screen.

[dull tree]

have that

should i move them to functions?

[maiden wadi]

Does it stay at 4 FPS for a while? Like over a minute, or is it a quick drop before returning to high FPS?

[dull tree]

4 fps just when leaderboard is visible

after i release TAB (remove from parent Leaderbaord) it goes back to normal fps

[hidden flume]

I have custom animations in my Weapon class, presented as Animation Montage. How can i use it in Animation Blueprint to blend it all with state machine? Like in Dark Souls. I just can't use Animation Montage in Animation blueprint

[maiden wadi]

@dull tree I would check out some of the graphics used maybe. Disable any textures being used if there are any. One other check might be to leave the AddChildToBox node connected, and disconnect the stuff running in the WCHPlayerSlotWidget Construct. If that still stops the FPS drop, just connect one at a time until it happens again. Otherwise you're in profiling land.

[dull tree]

its CPU thing

[wet hound]

How can i spawn Static mesh. Using add component require to pass an actor instance

[dull tree]

i think

[maiden wadi]

Well, start by removing the added Widget's Construct event. If that fixes it, just add one node back at a time to see if it comes back. SetText nodes really shouldn't cause that kind of behavior though, so if it's that, I'd be shocked.

[dull tree]

ok i got it

it was setting steam avatar

[maiden wadi]

Bindings?

[dull tree]

yep

[maiden wadi]

Ah, yeah. Probably only want to do that once on the Construct.

[hidden flume]

Could you please help?

I just need to know, is it even possible

or is it even right

Should i move deeper in this or go with Play Montage

[spark steppe]

is there a way to autoload soft object references if something tries to access them?

[summer bolt]

I still dont get it would a vc be possible

[maiden wadi]

@spark steppe What do you mean by autoload?

[spark steppe]

well my problem is actually probably my "code"

i'm trying to compare them to an instanced object, which i cast to a soft object reference

so i guess the soft object from the datatable is none, while my object points on the actual thing

i hoped the softobject reference to an object would be unique, too

but it isn't apparently

[summer bolt]

Could anyone else vc me through this issue

[maiden wadi]

@spark steppe AFAIK there's two ways to use SoftObject references. Either LoadAssetBlocking, which will stop execution until the asset is loaded and then continue, or AsyncLoadAsset which will basically bind an event to run when the asset is done loading, but also let the original execution run through. UImage does this rather nicely with some functions like SetBrushFromSoftTexture. You pass in a SoftReference to a UTexture2D and it does it's own little function binding and calls the herd pointer SetBrushFromTexture with the returned hard pointer. Alternatively you could go the other route and just use the default SetTextureFromBrush with a Softobject UTexture2D by just blockloading it, but that would cause hitches. I also don't think these are used for actual instanced objects. Unreal always loads an object into memory that serves as the default object, and that's what this loads up. The soft reference is just a string basically to where that object resides in game files so that it can be loaded if it's not. You don't normally use them on like actors or components.

[spark steppe]

[dull gale]

Hmm, is there a way to make timeline keys dynamic? As in change their values based on a variable?

[tight schooner]

@dull gale I don't think so. At best you can do some math/logic on the output, and change the playback rate of the timeline as it's running. But I think the curve tracks you make inside of them are fixed.

[dull gale]

I found an alternative for my specific case, making a timeline from 0-1 over the time I want and use the 0-1 as the alpha value for a lerp

[tight schooner]

@unkempt quarry I'm not sure why it's slow. 20 multiplied by 20 is 400, so one would expect such a construction script to be not very fast when it's creating potentially thousands of instances one at a time. Maybe a way to speed that up is by using the node, "Add Instances". That node takes an array of transforms and creates all the instances at once.

To feed the beast, you can collapse a lot of your logic down to a custom function with four transform-array outputs. Then your construction script just looks like a custom function node, and then the four arrays of transforms on it going into four Add Instances nodes. This would cut down on the number of times your logic is calling an add-instance function by a lot; I'm guessing that's the slow part, but I'm really just stabbing in the dark.

[dull gale]

Found out what was making it go on an acid trip, I was using "get FOV" directly from the camera.. that was actively having its FOV being changed, good job me

[unkempt quarry]

Alright, I'll try and give that a try, thank you

[tight schooner]

Apparently I did something similar in my project... Create an array of transforms and then "add instances". (I use the "min" node to cap the number of instances to 10,000 so that my editor doesn't crash lol.)

[unkempt quarry]

Is that in the function?

[tight schooner]

nah I didn't go the function route... I used a scratch variable. If I needed four arrays of transforms I'd probably go the function route to not clutter up the variables list too much.

[teal lantern]

How would I rotate something based on its local position? I trying to get a sword to to rotate as its swung.

[unkempt quarry]

Ah okay, I've made the function but it has broken everything lol

When I compile it only uses 3 instances out of the 5 and generates them in the same place
For the array of transforms, i don't think it'll work because I only had one in the first place coming from the map size

[vapid ibex]

I'm trying to set up some parameters for the actor's child object in the game during the BeginPlay event. But the pictured setup apparently doesn't work (neither the debug print node gets fired, nor the string value is changed). Am I'm doing something wrong here?

[tight schooner]

yeah, but at the end you're routing it via "Switch on Int" 0-4 to four different buckets... You can collect those transforms into four five arrays. Instead of going into five Add Instance nodes, they go into five possible Add Array (of transforms) nodes.

And then on your Function Return node, have five arrays of transforms on it

with your five transform array local variables feeding that

(in a custom function you can create "local variables" that only exist in that function and don't clutter up your main variables list)

[unkempt quarry]

oh, i've kept the switch outside the function

[tight schooner]

Put it in the custom function, cuz the function's job will be to provide five transform arrays

and then you feed five transform arrays directly into five Add Instances nodes

[unkempt quarry]

Will that only generate one type of instance?

[tight schooner]

Here's a mockup. You should endeavor to create this... It ain't pretty, but this is what I mean by one function creating 5 transform arrays, feeding 5 Add Instances nodes

... with the logic preparing those 5 arrays wholly contained inside of the function @unkempt quarry

@vapid ibex Do some normal debugging... Try putting a breakpoint (right click, add breakpoint) on that "Cast To" node and see if the execution is flowing the way you think it is

[unkempt quarry]

Ah, I get that now. Just stuck on splitting the transform array in the function

[jaunty stirrup]

I want to rotate the right arm bone of my character in the direction of the camera for aiming via Animgraph and the transform bone node:

[unkempt quarry]

wait, how did you get "Add Instances" with the array, I can only get "Add Instance" with a single variable

[tight schooner]

There's a plural one. It exists...

[unkempt quarry]

am I being dumb?

[tight schooner]

@unkempt quarry huh. Are you on the current version of Unreal Engine?

[unkempt quarry]

No... 4.24.3

[tight schooner]

that seems newish...

[thorn ermine]

Are you asking how to calculate this aim rotation? or where to apply these nodes?

[unkempt quarry]

I'll update then lol

[arctic finch]

how would one go about putting in some code to prevent the player from falling due to the level streaming level not being loaded yet when game starts? ive been stuck on this for like days now, just cant figure it out.

[tight schooner]

@unkempt quarry fwiw here's another mockup illustrating five local array variables being made and then fed into a custom function's Return Node for output

[unkempt quarry]

ahhh, i feel stupid haha thanks dude, I'll let you know when i run into problems after updating

[tight schooner]

@unkempt quarry Good luck. Feel free to ask the channel for further help... I gotta run in a few minutes. The node def. exists though, but IDK when it was added or why you don't see it... https://docs.unrealengine.com/en-US/BlueprintAPI/Components/InstancedStaticMesh/AddInstances/index.html

[unkempt quarry]

Thanks again @tight schooner

[tight schooner]

I haven't messed around with level streaming personally but isn't there a "latent" node related to level streaming that has an output exec pin for when streaming is finished?

maybe you can figure out some logic based on that

[arctic finch]

@tight schooner ive came close, just cant figure it out.. it's kinda demoralizing lol

ive thought of many ways to do it, just cant figure out how to actually do it

if the player spawn is under the first loaded tile, everything is cool, if the playerstart is not under the initial loading tile, thats the problem, ue4 spawns the player in b4 the tile actually loads. i have like 16 tiles, and 10+ playerstarts.

i suck at bp's also.. alot of learning yet to do. like i have the fix in my head.. just cant figure out how to do it in bp's

easiest way i can think of is to disable the gravity of the player, untill all tiles are loaded. when it is, enable gravity again, remove the loading screen.. ive tried many ways to attempt this, but always a no go.

[tight schooner]

Instead of having the player automatically spawn, maybe figure out some way to delay that until streaming is complete. Usually UE4 spawns everything defined in "maps & modes" in Project Settings but it's also possible to do it explicitly through game logic in a manager class (e.g. Game Mode)

You have a manager BP that checks for some condition (level streaming) and then spawns a pawn and makes a PlayerController "possess" that pawn

I haven't done that myself so I only know it in theory

Or have each pawn spawn with a safety collision box underneath, and removes that box once streaming is finished

(and enables movement I guess)

[vapid ibex]

If I call DestroyActor on actor within a collision volume, will that trigger OnEndOverlap event for that volume?

[shy current]

How can i teleport an object in the center of an object?

[faint pasture]

Define center

[unkempt quarry]

@tight schooner that has somehow caused more lag and still generates them inside each other (lags in the editor but not while playing)

Fixed the location problem, but when I go over 600+ tiles it starts to lag while playing

[runic osprey]

Hey everyone, quick question. Is there a way for me to make one button (an actor that I made), to do mutliple different things? Almost like instancing it. For example, I want to have one button in a level spawn a cube at the buttons location, then I want a second button (using the same blueprint) to spawn a second cube at that buttons location

The reason for this is I don't want to have a different button blueprint for every single use of a button

[jovial dirge]

I can posses into the boat but why can't I posses back into the player?

https://media.discordapp.net/attachments/225448446956404738/815044536547409960/unknown.png

[dawn gazelle]

That sounds like you'd just need to place the same blueprint in the level, so long as you designed the blueprint to spawn a cube at its location, then any copy of that button you drag into the level would do the same - trigger the button, spawn a cube at that button.

If you're thinking in terms of "I want this particular button to open this particular door", then what you can do is expose a variable on your button that takes in a reference to your "door" object that you can set. Then when you have the door and the button placed in the level, you can make the button reference the door. In the code, you would make it so when you push the button, you trigger a function on the referenced door (the reference being fed in from when you placed it in the level and set its reference) to open said door. This would allow you to have as many buttons and doors as you like in the level, each button opening a specific door you've specified in the editor.

Similarly, if you wanted many buttons, each spawning different things at the buttons location, then you can have an exposed static mesh variable that the button then reads when it is spawning so it spawns the appropriate object. And this can be done all using the same blueprint.

If I use seed in my parent BP and apply SK meshes randomly. Then create some children BP, would every child gets an unique mesh everytime?

Is there an equivalent in blueprints?

[thorn yacht]

Hello everyone! I am working on camera setup in my game and need help.

So there are main character and mounts(horses) that player can ride in the game. And I want to implement switching from 3rd person to 1st person and vice versa. So I need camera that will always follow character even after player controller's possession to horse. And also this camera should always receive pitch and yaw input from mouse.

Disabling bAutoManageActiveCameraTarget in PlayerController didn't solve the problem because player camera can't receive input after unpossession anyway. Also I tried to use custom PlayerCameraManager, but with these I can't use SpringArm.

So how I can implement camera with SpringArm, that will always follow specific pawn and receive input? Thanks in advance and sorry for my English

[tranquil dome]

Any idea why character movement acts as if it's glued to the floor even when going high speed over bumps ?
Would like to take flight when going over small bumps like blue line, but it acts as if it's a vacuum cleaner and sucking the floor.
Would also like to avoid physics if possible, want to feel as arcade as possible just not glued to the floor

[maiden wadi]

@nova hinge I can't speak from a Unity standpoint. I tried reading up on the ScriptableObject. It's a bit confusing to me, possibly the reason I never could get into Unity. From what I understand from what you're looking for and the way it's phrased, that sounds like a Datatable? At least that's the usual thing you use to store a lot of data like that. Some people use UDataAsset as well. It could also be what you're looking for since you mentioned Functions, Datatable is basically a CSV file where you can populate the row of data into a struct to use.

@stark trout Scene Component is not editor only. It's the basic ActorComponent that can have a transform.

[stark trout]

Fixed it. It was my bad, apparently all my scene components and arrow components had "is editor only" ticked. Unticking that solved my problem

[nova hinge]

Great! Thanks for the leads. I'll look into both of those.
FWIW: The "ScriptableObject" is a bit strange. It's essentially a class that doesn't get instantiated or attached to a gameobject, so it can maintain data in a platonic way.
It's great for things like bullets, where each copy of the data can be a different type of bullet, or enemy, where each enemy has different stats.
I'll look into both, but I'll start with UDataAsset and see where I get to.

[maiden wadi]

@tranquil dome I don't believe that the default character movement can handle that. I'm not finding any settings for it at least. One thing you might attempt, is a small tick function. It'd need a lot of checks and such for it. But I think you could manage it by checking and cacheing the floor and velocity values, and doing some vector math on that to determine how and when to launch the character to simulate that behavior.

[tranquil dome]

yeah, playing with slope angle helps a bit, but if i lower it too much, i can't go up the slope anymore, thanks for the advice @maiden wadi

Does "Does Save Game Exist" work in final builds? I am having an issue where after switching from development to shipping builds that node seems to always go true even if there is no save file.

Never had a problem with it in shipping builds. You're certain you checked the shipping build's save location and not the project's save location?

When deleting the save files I mean.

Yes, I fully delete all files in the build destination before packaging a new build

[maiden wadi]

Not sure then. What engine version?

[quasi frost]

[maiden wadi]

@quasi frost Hmm. That's my bad. I forgot that savegames in shipping aren't saved to the game files. They're saved to Appdata. If you open up a folder browser and go to %appdata%, go up one folder to the actual AppData folder, then to Local, find your project name's folder. In there should be a Saved file, in that is a SaveGames folder with the actual saves.

[meager marsh]

Hi, I'm having some trouble with my project in Unreal but I'm not sure if it has to do with blueprints, may I ask here or in another channel?

[maiden wadi]

@meager marsh The Default #ue4-general channel is good for generalized questions. If it generally has anything to do with Blueprints, you can post it in here though. At worst you'll get referred to another channel.

[meager marsh]

Ok, I'm doing a space game, and I want to have a flying movement for my character, so that it can move and rotate in the three axis. I have set the view pitch min to 0 and the maximum to 359 (just like in the view pitch yaw), so that it goes all the way around, but when the character is facing either 90 or - 90 degrees in the pitch, everything gets crazy. Hope you can understand it with the picture, I have a video as well, I'll upload it if needed. Any help would be appreciated, I'm almost new to the Unreal Engine.

[spice sequoia]

I have a function BP set up like this - is it normal behaviour that the Exec pin on the return node always continues on regardless of whether the Boolean is True/False?

I assumed this might work as a sort of gate and the flow would stop at the branch but whenever I slot this function into another BP it seems to carry on through this function regardless of whether the Branch is true or false

[faint pasture]

Whoa whoa whoa that is gross. You do not want to do that at all. A function has to reach the return somehow

What it is probably doing is it is probably not taking the true path from that branch, but since you don't have a return anywhere else, it just does the default return. A function has to return

You can think of it like there is a blank return node plugged in to every other execution path as well.

That is, if it works like that. The only other option is to crash I guess?

[maiden wadi]

@meager marsh You don't want your view pitch min to be 0. Pitch goes from -90 to 90. Both Roll and Yaw go from -180 to 180. So pitch only has 180 degrees of movement and Roll and Yaw have 360 degrees of movement.

[dawn gazelle]

You'd effectively want your return node to return a boolean that you can check against after this function is run. On the true branch there, the returning boolean should be true. On the completed pin add another return node and set the boolean return to false.

[meager marsh]

Isn't there any way of making the camera rotate over that range?

[faint pasture]

Yeah as is, that function will only ever return the exact same thing every time you run it, no matter what you give it

[maiden wadi]

Thankfully in blueprint, all unused paths will just return with default values. Still good practice to specify the returns, but it won't do anything bad if you don't.

The function doesn't return anything though.

@meager marsh I'm uncertain. I've never tried true 3d spacial flight. The thing is that most stuff is based on rotators. So... You're facing straight. If you look forward, pitch is at 0. Yaw is at 0, Roll is at 0. If you look directly up from there, Pitch is now 90, Yaw and Roll still 0. If you look "up" one more degree as if you're bending over backwards. Then pitch changes to 89 instead of 91, and Roll and Yaw will get inverted from 0 to 180. So rotators can define that behavior easily. But the problem is the movement components. What happens if you don't set the minmax view stuff in the camera manager?

[spark steppe]

is there some way to linetrace against the character mesh instead of physics bodies?

i've enable trace complex in the linetrace setting, but it wont respond to the mesh ok it responds now after setting per poly collision to true on the mesh asset + character, however i dont want it to be enabled all the time, and there seems no way to disable it on runtime?!

[meager marsh]

@maiden wadi When it is facing in 90 or -90, the character will stop moving and you have to move the camera around in the yaw until it finds a position where you can move it, to face "further" the 90/-90. The problem is that this is not smooth, and you can't make a looping or anything like that. Also, when the character rotates the camera doesn't, so when you are facing in any angle the camera moves the same way as if the character was in 0 (ex: in 0, in the pitch the camera goes from his head to his feet, but in 90 goes from the chest to his back, and something similar happens with the yaw). All of this is very annoying, as there is supposed to be no direction, and the camera should just follow the character. There is a game called Adr1ft which has something similar to what I want and it was also made using the Unreal Engine 4.

[wet adder]

Hello guys, I need a little advice. This code is to display game over text, however I want it to only appear if the game over boolean is true. Any ideas? 🙂

[hushed pewter]

Hey i cant get my widget too correctly call on the array (Im currently learning arrays)

Im not sure if its something wrong with my add fuctionality

Ive been on this for a day and not too sure

[quick lark]

Is it possible to use a blueprint interface in c++?

[maiden wadi]

@quick lark Unfortunately nothing blueprint can be used in C++. It's a one way street.

[rough jay]

you can use both tho comfortably right and translate bp to c++? not really translating but know what the node means in c++ and using it there

[dawn gazelle]

What this error is telling you is that you're attempting to access an array index that does not exist.

Array indexes start at 0. When you add your first item to an array, it can be accessed at index 0. The next item you add would be accessible at index 1.

In your current set up, you are attempting to get an object from your "Demo Array" at index 4. Unless you've added 5 items to that array, you'll get errors like you are seeing.

[hushed pewter]

No my array has more than that

I think the main issue is that The variable for DemoArray isnt connected too the actual Array

I think im trying too pull from the structure instead and dont know how too reroute it

[maiden wadi]

Where are you populating Demo Array. Because your game logic is under the impression that it only has one entry, not at least five.

[hushed pewter]

Its pre imported

[maiden wadi]

Not sure what you mean by that?

[hushed pewter]

Before you laugh. I have a friend who specialises in drawring female anatomy and he asked me too make him a dating sim.

[true valve]

I've a parent BP with random SK meshes and materials in its event beginplay using Random Stream (seed). Then created some children BP, when I spawn these children would the random stream gives each child unique sk mesh and materials or they all will get the same one?

[maiden wadi]

That is a datatable. Not an array. You have the array named DemoArray. It was the second picture you posted. Where is that being set?

[hushed pewter]

Oh fuck right i completely forgot the data table got turned into an array

Got this here

I assume its just pulling only 1 row

Should i use a loop too add all rows

[fleet stump]

I got some issue with climbing/hanging on the wall ... when the character jumps to the to wall to hang on it it just teleports him on the same location every single time. This started to happen when I attached Capsule Component to "MoveComponentTo" tab can someone help me please ?

[maiden wadi]

@hushed pewter You should get the datatable's Names array, and for loop over that with the GetDataTableRow.

[wheat pelican]

Hi! I'm currently making an RTS Survival type game and I've just implemented a basic inventory system, but I have a problem that I'm trying to get some help about. When I collect an item it goes to a "general" inventory instead of the unit's inventory who picked/harvested it.
I want to make it so every unit has an individual inventory but I don't know a way to "split it" and make it individual.
I can drop the bps here if that helps.
Thanks in advance

[maiden wadi]

@fleet stump I don't think you can do that with a root component. The capsule's position in relative space is updated when it's moved. This isn't exactly true for a different component in the hierarchy, it's relative space is changed when it's moved. But when you move a root component like capsule, once it's moved, it's back at 0,0,0, because it is the root. If that makes sense?

[fleet stump]

oh ... so what can I do to fix that ?

[hushed pewter]

Got no idea how this all goes together

I havent used oops before either

OR atleast, not these kind

(Insert dance gif here)

It worked

Thanks authaer

[plain cedar]

how would I change spring arm length in a pawn from the player controller?

[maiden wadi]

@fleet stump Pretty much make your own timeline or tick function for it somehow. Most things that move root components are actor componennts added to the actor, like the Character Movement Component.

[astral fiber]

Any idea how I can get the name of the child ("Cube") of the ChildActorComponent ("ChildActor")?

When I try it with the node "GetChildComponent" with ChildIndex 0 it returns me the default root and not the "Cube"

ChildActorComponentName.DefaultRoot gets returned

[silent comet]

https://gyazo.com/07416485da6fb6d28ab655ff558c0ce4 Hi Guys. My problem is when i shot from right corners, my Bullet ( Witch comes out of my Gun ) collides. Can anyone tell me how i could fix this. At this point the bullet should not collide with the wall and hit the END of the Trace aka where the Crosshair is.

[maiden wadi]

@astral fiber Can't get the same results. Doing exactly what you did in the second picture prints the correct component.

[true valve]

Do you how to get random stream to work on instances?

[astral fiber]

@maiden wadi Thank you for checking it

[pine trellis]

does anyone know if its possible to add a scene capture component to the camera, like actually inside the camera and not addes as a child compnent?

[drowsy mauve]

is there a way to set an input priority?

I've got a sidescroller. My character can move left and right with A and D. I'd like to set it so if I'm holding D, then hold A afterwards, A will take priority over D

Or vice versa

[maiden wadi]

@drowsy mauve It's hard to say how you would want to handle that. If it was me, I'd make some key functions in my player controller. Iterate over all of the axis mappings that use that axis name. Then find which one has the shortest down time that is also pressed. Use that key's scale for the AxisValue.

Then it won't matter later if you have more keys, or rebind keys, or anything like that.

[astral fiber]

@maiden wadi When you tried to get the ChildComponent of the ChildActorComponent did you give the ActorComponent a class?

I tested it without giving it a class, then it works, but when I give it a class it wont

Mhm.. with some classes it works, with others it doesnt

@maiden wadi I think I solved it, when the ChildActorComponent class has no components attached to it (like static Meshes for example) then it works with childIndex 0. When the Blueprint Actor you wanna use as child Actor has Components under its RootComponent then you get it with ChildIndex 1.

[dusky harness]

How can i check if variable is the same for specified time?

[maiden wadi]

@drowsy mauve

I imagine this should work for that.

[astral fiber]

By default your ConstructionScript makes a Call to the parent ConstructionScript.

When doesn't it?
I allways thought when the ConstructionScript node has no connection to another node?
But I just had the case, that I had other nodes inside the ConstructionScript method, but not connected to it, and it didnt call the parent ConstructionScript.

[maiden wadi]

@dusky harness You can't really. Not without constant checking, which is also prone to failure if something sets it and then sets it back in the same frame before your check comes along. The best way to handle something like that is probably to have something like a struct for the property. Put your original property in the struct along with an extra one that is a float. Then increment that float on tick or where ever, and then you can make a function that both sets that float to 0.0 and changes your property. And you use that where you would normally Set the original property.

[velvet nymph]

Hey guys, I'm trying to set an animation blueprint at runtime (and have it start playing). When I use the top SetAnimInstanceClass node it works but when create a AnimationBlueprint variable that can be set from the inspector and try set it that way it doesn't work. Is there something I'm missing here?
It seems to run but no animation plays

[worthy frost]

what is animationblueprint reference?

seems a bit strange to use a object reference then get the class

but it should work, as it should just return the uclass just fine.

[velvet nymph]

I did try with AnimblueprintClass variable also (that's the other node) but still didnt work 😆

[worthy frost]

did you set it

to something?

[velvet nymph]

yup

[worthy frost]

remove the Animation Blueprint variable

and set the class to BP_RPMAnimation

then connect the class node back up (Anim Blueprint Class)

[marble tusk]

I think there's a node that calls the parent construction script. If it's not hooked up it won't call it.

[astral fiber]

@marble tusk Yes, but it does this by default. It seems when your construction script method does not contain any node, then it calls the parent construction script automatically. But when you have a node in it, even if it is not connected to the Construction Script "entrance" node, it doesnt call the parent any more and you have to call it manually as you said.
But shouldnt this behaviour be changed, so it only doesnt get called when it is connected to some other node?

[worthy frost]

does not work like that

you need to delete the construction script from the child

then it will auto call the parent

[astral fiber]

@worthy frost what do you mean with delete?
As far as I know you cannot delete a Construction Script, it will always be listed on the left side

[worthy frost]

then you need to call parent

else your child will override the parents construction script, and it will never call the parent.

no different to c++, where you have to call Super:: in your overrides to call the parent function

[astral fiber]

delete is greyed out

[worthy frost]

yeah, so you need to add Call parent node

and connect it up

[astral fiber]

Yes, but if it is empty, then it will call it automatically

[worthy frost]

no

[astral fiber]

yes

[worthy frost]

where does it say that?

[astral fiber]

I swear 😉

It happens on all my blueprint classes I ever made

[worthy frost]

sec let me test, maybe construction node is special cased

but it doesn't happen with normal BP nodes

well this is what happens when you never use construction node 😄

[astral fiber]

Thanks, so I just wanted to know on what it decides when to call the parent and when not. Based on my testing it seems to stop that behaviour when there is a node in the construction script

[worthy frost]

yeah

[astral fiber]

But I couldnt find anything in the docs

[worthy frost]

but normal functions, maybe that is the same... maybe the bp compiler detects if any pin is connected to the exec

and just does not call that scripts version, then automatically tries the parent

[astral fiber]

Jeah at the beginning I thought it checks if it is connected to something, but I had a class where it does not connect to anything and the parent doesnt get called. I think this is because there is an unconnected node in the construction script

[velvet nymph]

Ah I think I get it now. I have to set the class to be of type BP_RPMAnimation. Is it not possible to store it as a generic "AnimationBlueprint" type so it will work with other Animation blueprints and be set in inspector?

[worthy frost]

@astral fiber i can confirm the same behaviour does not happen with normal functions

had this in parent,

this in child, and the print never got called, till i added the call parent node

@velvet nymph what do you mean?

[astral fiber]

@worthy frost ok, so it seems this behaviour is only inside the construction script. Thanks for testing

I guess I just add the call manually to very BP Class now

[worthy frost]

if you need to call parent

then i would just to be safe

[astral fiber]

@worthy frost yes makes sense

[worthy frost]

@velvet nymph did you see my post above ?

[velvet nymph]

yep! trying it out now

yup works like a charm thanks @worthy frost

[marble tusk]

Don't child blueprints automatically have that parent node? If anything I'd think the expected behavior would be to not call the parent script if the child script is completely empty without the parent node. But that's just me ¯_(ツ)_/¯

[worthy frost]

but sometimes you want to override or disable a parents feature

in a child

we do that in c++ sometimes

[marble tusk]

Yeah, what I'm saying would make that easier. Requiring the 'parent: construction script' to be called in order for the parent script to run

Instead of also doing it when the child's construction script is completely empty

[surreal swallow]

The standard for other object oriented languages is that child classes act just like a base class by default unless you override methods, so unreal does that too

The idea is that you specialize the base object. “This cat is an animal except x / but also y

[stoic nebula]

hi i wanted to know if anyone had any idea how i could change my character's mesh through a triggerbox :p (I try to make a playable level where you can change your character) thank you in advance if anyone has the answer to my problem 🙂

[surreal swallow]

@stoic nebula make a new blueprint, add a box collider component. On the box collider component in the hierarchy, right click and add an on overlap event. Plug that event up so you get the overlapped actor and cast it to a character. If the cast succeeds, get the character mesh component and set the skeletal mesh to whatever you want to change it to.

[stoic nebula]

ok i will go try thanks a lot 😄

[zealous moth]

does anyone have any resource for fluid mechanics? I am imagining using several tiny spheres with physics on...

[true salmon]

Hi, I'd like to ask a question about how the material in this screenshot is created - it appears to be a simple cube with some different params defined based on vertex data, but I can't find where the vertices dictate where is the wall region, glowing region, the bevel.. is there some blueprint I'm not yet finding? Looking for the one that defines the edge region (glows and bevels)

btw that is the nDisplay template

[zealous moth]

@true salmon can you screenshot the material?

[true salmon]

this one?

[zealous moth]

yeah can you zoom in onto the top left of it?

[zealous moth]

the texture is a grid right?

[true salmon]

yea I see those colors being lerped, but I can't find where the boundaries are defined - for the bevels and the glowing part

[zealous moth]

i think its the texture sample

not gonna lie, the spaghetti makes it hard to understand

but it looks like it lerps between coords using a pattern

[true salmon]

I think you're right, but how do you check if the texture is a 'grid' - apologies, I'm fairly new to UE4 materials

[zealous moth]

click on it and check the texture on the left details panel

[surreal swallow]

Looks like it’s using the vertex colours to make the glow

Can you paint red or green onto the vert colours?

[true salmon]

Yea I must be looking at a different view that doesn't have that information - all I see is that there is a "Vertex Color" node that feeds into a "Multiply" node that affects all the parametized colors - no idea where this vertex color is coming from. But it does make total sense that it is being sampled on a grid - and looks great too

[high sapphire]

Man I'm good at bugging out UE, apparently
So I have this health bar, the percent value is bound to a function that gets the player's current health/max health and takes that value
This should work. It does not.
Instead, as soon as the player's health drops to 90 (so 0.9), the bar goes to empty and stays there until the player dies.
I've tried remaking the binding twice, both from scratch. Nada. If the player's health isn't 1 (100), the bar displays as if the player is at 0 health.

[coral gazelle]

quite sure its because the convertion/casting node is rounding down the float, try fully using integers

having 0.5 health and not dying 👁️

[flat raft]

Anyone know what Get Base Aim Rotation does?

I read the docs, but I don't understand how it differs from FwdVector

[unkempt adder]

Hi nat, dont know if you got your problem solved but the way i achieced is that i had a bp interface function set and takes as the damage as input and then i just feed in the values in my main chars bp. From there i call the interface function in my umg bp and subtract it from the health (which is 100 at its max) and then i use map clamped node to get it confined btwn 0 and 1.

As somone said casting may cause issues but i dont know about it 100 percent.

Hope that helps!

[rough jay]

ones a vector ones a rotation thats one difference

[flat raft]

Ahh true!

[patent wasp]

Is there a way to see a static meshes bounds details inside of the static mesh viewer panel?

[mellow forge]

I'm making a thing where you pick up flowers. I will have lots of flowers with slightly different functionality. So I made a ChildBlueprintClass.

I have an Array of "FlowerParent" that I use to store what I can pick up. I call "Pick up flower event" on the flower.

But, in this array I also add "FlowerChildClass". Seems to work so far (it gets added)

But now I want to cast to the parent logic, "Pick up flower", the event fails.

Is there any node I could do before I cast here? Get parent something something? Also I am I making sense?

EDIT, NEVERMIND OVERWROTE THE EVENT I WAS TRYING TO FIRE WORKS FINE 😅

[devout tide]

how can I get an object's rotation relative to a direction?

[queen urchin]

Hi guys. Cant attach 2 timers on 1 function. Someone saw that before? Dont know how to work around :/

[high sapphire]

RE: Why not just use a float for health?
I figured using an int for health would make the math easier, I guess was my logic for it

[silent comet]

Can someone give me a Hint on how to Deal with it ? :)

[small trench]

Is there any particular reason as to why my widget blueprint wouldn't show up in the HUD class list of my game mode?

The only way I'm able to get my widget blueprint to show up (or the 'HUD', which I don't unerstand why it deserves its own name) is to create it from my character's BeginPlay. But it makes no sense to do it like that since the hud is game mode specific.

[maiden wadi]

@small trench HUD is not a Widget. HUD is an Actor class that is spawned for the local player controller.

HUD is an older class. It has functions for drawing simple stuff like text or lines on screen. It used to be used for simpler games. Widgets on the other hand are a newer UI thing. You can create and display widgets from anywhere, although it's common practice to do so from either the PlayerController or HUD. I like HUD for storing widgets personally as it's meant for UI anyway.

[trim matrix]

Hey guys! I asked a question in level design to be a good boi about randomly generated rooms, but I regret it I shouldve asked it here, it's dead air over there. Can someone check it out or should I ask the same question here? I just don't want to break the rules.

[small trench]

I see - but my UIs are game mode specific, so logically I would check what game mode is currently 'active' and draw the widget based on that? Is there no better way?

[maiden wadi]

@trim matrix Out of curiosity, where did you read that you can't stream the same level twice? I've never messed with level streaming yet, but I'd be curious to know. I would have assumed it would have just copied an instance of the level in for each time you streamed it.

@small trench Do you have different widgets based on the game mode, or do you want the same widgets to look different based on the game mode?

[small trench]

Diff widgets based on game modes

[maiden wadi]

If I had to manage that, I'd probably do the same as I already do and handle spawning and storing widgets in the HUD class, and then subclass my HUD and split the logic there, then select the different huds for each game mode.

[trim matrix]

@maiden wadi Well I always search on forums before throwing a question here, not to bother you guys all the time, and some users said it there. Also tried it manually, just dragging multiple in the Persistent Level and it just doesn't allow it

[maiden wadi]

@trim matrix Odd. I suppose that makes sense. So you could alter multiple levels and have it reflect in their defaults. Out of curiosity though, why not make each room an actor?

[trim matrix]

Yeah that was my fallback plan. I was afraid to use child actors as my interactible furniture inside the "floor plan" actor. I wanted to keep them as standalone actors just to be sure

[maiden wadi]

You could just spawn an actor of the room type and it could run it's own construction logic to procedurally generate itself and set up randomized stuff on the components that it could add to itself. You could use spawn locations for different layouts and such.

[trim matrix]

But I wanted to avoid spawning at construction and randomness as I wanted to see and easily rearrange stuff

Even though it would be a cool feature to randomly rearrange furniture, I wanted to have nicely manually setup rooms

Thanks for the help though! I'll try my luck with actors, just wanted to make sure I can keep level streaming out of the pictureÍ

[maiden wadi]

If your furniture stays in the one room, you could just use components for those. But otherwise yeah. You'd have to make some scene components for placement and spawn the furniture at beginplay.

[trim matrix]

Thank you!

[prisma stag]

Hello, I followed Ryan Laley's grid placement video and I got it to work as you can see in the picture, however, the machine (Brown Capsule) you see in the picture is snapping just fine to the center of a one by one block. However, as of right now I got it working so that when you move the camera it snaps every 2m but it isnt centered in a 2x2 area as you see in the picture.

[junior mural]

the mesh is probably not centered to root

in the bp

[tight schooner]

@queen urchin yeah setting a new timer on an event/function resets any prior timer running on it

[gritty plover]

Is there a better way of getting the player's speed that isn't based on the player's input?

[maiden wadi]

That's not based on their input though?

That's usually how you'd get their speed.

[gritty plover]

Hmm. I might need something custom them.

[maiden wadi]

What are you having trouble with?

[gritty plover]

So, for example...

If the player is moving through the air at 500mph, but not holding any movement keys, that float will result in 0.

[maiden wadi]

Are you using a movement component?

[gritty plover]

Yeah

Well, it's just the default CharacterMovement thing

[maiden wadi]

That's odd. Velocity shouldn't zero out like that. I can test really quick. You're using CMC, with flying mode, or?

[gritty plover]

Not flying mode...

[prisma stag]

No. I know it's centered because placing it with a 1x1 grid system works fine. It's trying to get it centered in a 2x2 area moving by 2m increments.

[maiden wadi]

@prisma stag In your picture on the right. Are those four smaller blocks placed together or one single 2x2 block?

[prisma stag]

Those are 4 smaller blocks.

[maiden wadi]

Then you need some logic to detect that there are four smaller blocks there, and if so, place the object in the center of those, rather than at the center of one block.

[prisma stag]

Its not that I want it to be placed in the center of 4 blocks if they are there, its just that I want the machine to be placed in the center of a 2x2 area.

[maiden wadi]

I'm not sure I'm following then. If your 2x2 area is 4 1x1 blocks, then you need to detect if the player is trying to place it at the center of 4 1x1 blocks and if so place it between those 1x1 blocks.

[prisma stag]

Hopefully this helps, the problem with placing the block in the center if the 4 blocks are there is that the machine may not always be placed on blocks. The blocks were just used to show a 1x1 area. So in here, you can see the 2x2 made with the 4 1m blocks, and when I pick up the machine it snaps to a certain block, then moves in 2m increments as Ive set, but I would like it to snap to center.

[maiden wadi]

Ah. All you should need to do is offset the machine's grid snap location by half of a normal grid size.

[prisma stag]

That's what I was thinking however, if I offset the actor once placed, the actor would be in a different spot compared to where the "hologram" was showing it would be placed.

[maiden wadi]

How are you differentiating the grid size in the hologram? You should be able to use the same place in logic to also define the offset.

[prisma stag]

I get the location which is where the hologram is set to, then use "Vector Snapped to Grid". I might be able to define an offset after that. Maybe.

[errant path]

hello

it s normal that when i do this in runtime, the sound is play directly

(my audio component is autoActivate=False)

[maiden wadi]

@errant path Looking at the CPP, it looks like it only calls play on that sound if it was already playing.

[errant path]

ha ok

so maybe if i force stop before that will be good

yes perfect

it must read rhe source more othen 🙂

[maiden wadi]

Haha. I've made it a pretty big habit since I started learning CPP.

[errant path]

yes it s good habit ^^

[runic parrot]

Hi! one question, i have an actor with a skeletal mesh and a static mesh. I want to check on construct if the skeletal mesh is empty, if it's not empty, remove the static mesh.
how do i check if skeletal mesh is set?

[dawn gazelle]

Do an is valid check

[runic parrot]

it always return valid

i guess that it's because they do have a skeletal mesh, but it's empty

[nova sedge]

Is there a way to use a render target to render the game scene, display on UMG, and allow you to click on it and translate that click to a line trace in the scene capture?

[dawn gazelle]

If you're checking on the component, yea, that'd come back valid, you want to check the skeletal mesh set on the component.

[runic parrot]

you can get the position of the mouse on click, and override the mouse click event to something else so you check when that happens

[left niche]

right click and convert to validated get, makes things easier

[nova sedge]

Thats what I'm thinking, but I havent dove into how I can get the click location from the Render Target Texture to a location on the 2d scene capture. I'm guessing there will be a lot of math involved

[runic parrot]

this worked, thanks ♥

what is your final intent newsom?

[nova sedge]

I'll use my game as an example. https://sbnewsom.itch.io/feducia The scene is rendered only on the left side, but for the game jam, all I did was just shift the camera. But it'll still render the whole screen. I want to consolidate the camera to a specific area so I can optimize the rendering and have more control over the visuals. Basically instead of shifting the camera, I want the camera to be properly displayed in a specific area on screen.

Also having control over hte render target would allow me to reduce the resolution and get the aesthetic i've wanted.

But its a point and click, so i'm unsure if I'll lose that ability

[runic parrot]

i'm not that advanced into unreal, sorry : (
what about oclussion culling? maybe that can help with your problem

[nova sedge]

I'll look into it. No problem. I'm just happy to vocalize my problem and have someone listen. I mostly just discuss it in my head. Thanks though. 🙂

[median spire]

Is anyone here especially experienced in sidescrolling or isometric views?

[stray island]

Opening a copy 4.20 project in 4.23 made me lose my timeline float tracks even though they still have the outputs , is this normal

[thorny relic]

Shouldn't happen, it normally doesn't even touch the assets when you convert

[stray island]

Oh i remade the timeline floats and the engine deleted them again , it might be a bug in 4.23.1

Nvm fixed

[maiden wadi]

Make a hollow box.

[hushed pewter]

ive been following a tutorial about widgets and am not sure why this isnt updating?

[maiden wadi]

Well, for starts, that IsValid will never return IsValid. So that Set TextVar will never run.

[hushed pewter]

Removed it

Still dont work

[maiden wadi]

No idea other than that. Can't see any other execution that you're doing.

[maiden wadi]

Not really sure what you're doing there. I see two different execution lines. It's really bad practice to get variables from other execution lines. If you want to use variables in multiple places, you should save it as a variable and get it in the place you need it. But start simpler, and disconnect the ToText from the SetTextVar, and input something manually like "Hello World" or whatever. If that changes your widget, then you have a problem with the way you're getting the text out of your array of structs.

Also. Don't drag those long blue lines down like that. That's what I mean by getting variables from other execution lines. You're already setting that created widget into a variable. Use the variable to set the text.

[fleet stump]

Guys can I freeze Mesh socket rotation ?

[hushed pewter]

Still getting the default variable values.

[quasi frost]

Why does this not work to remove any other instance of the widget before spawning a new one?

Ah nvm just had to uncheck top level only

[maiden wadi]

@hushed pewter I'd place some prints on UpdateText. See if it's actually getting called in your execution. Where are you originally calling that from?

[hushed pewter]

Im just calling it from a regular arrayt that worked before

[maiden wadi]

This is in the PlayerController?

[hushed pewter]

-_-

One second please

Twas but a fuck up

Cheers man

[maiden wadi]

What was it? Cause looking over your execution, that should have changed if the binding was running.

[hushed pewter]

The thing i was running is a scene controller

I had too have a custom event come from my actualy player controller

[minor lynx]

anyone know of a way to get this list in a blueprint so I can possible make a dropdown in a widget with them?

[dawn gazelle]

Can't really get reference the map objects I don't think. What I would do is make a struct called "level container" or something that holds any variables you may want to reference about the level, then create a table based on that struct so you can input your valid map names into the row names of the table (yes, you'll have to do it manually).
Then when you need the map names, you can do a "Get Data Table Row Names" to get the appropriate level names from your table, and if you need to get data about that particular map, you can add it to your table, and get its data with "Get Data Table Row".

oooh honestly i like that even though its manual it will allow me to create custom names and maybe other info about the level in the struct. thanks for the idea

[maiden wadi]

@minor lynx Also worth noting that for ease, you can now open levels via SoftObject Pointers. Which means you can use those in your struct instead of strings. Easy dropdown selection vs potential typos.

[minor lynx]

yeah thats what made me think i could potentially get a list to use. you can "Open Level (by object reference)"

[maiden wadi]

Yeah. Unfortunately that's also done via the content browser stuff. You wouldn't likely see that sort of thing made for a game anyhow. Developers tend to hide testing levels and whatnot, and you wouldn't want them showing up.

Hey everyone. Have a slight problem with my UI not reacting to mouse clicks. Screenshots following

Creating UI in FirstPersonHUD

initializing UI in the widget

[maiden wadi]

@iron bobcat You should probably move the SetInputModeForUI to the event construct too, since you're already getting the controller there. You can IsValid the controller instead of casting if you don't want that note. But none of that will help with the mouse issue. Do you have buttons in the widget that aren't clickable, or?

[iron bobcat]

I have two checkboxes. They don't react to hover or click

Will do

[maiden wadi]

Hmm. That's odd. You're certain that nothing else could be on top of them in the hierarchy? A random panel or something over them that is hit testable?

[iron bobcat]

I have a remove all Widgets node in front of the branch, but I can comment out everything else and try that. Second

[maiden wadi]

I mean more in the widget itself. There's nothing accidentally overlapping on them?

[iron bobcat]

There's nothing else on it

[maiden wadi]

And both of those have their Visibility settings set to Visible?

[iron bobcat]

Yes

That's why I'm at a loss. I'm not the most experienced when it comes to UI, but simple stuff like this I can usually manage

[maiden wadi]

Even a default checkbox is unclickable?

[iron bobcat]

This is the full UI code

Yes. I added a standard button with a print string node just to test that

[maiden wadi]

I'm not sure you want to be creating widgets on tick?

EventReceiveDrawHUD is called on tick. Once per frame. So, you might be just creating a new widget over top of the one that has actually registered the mouse over or click, but you wouldn't see it.

Well, you definitely wouldn't see it. Cause it would get removed, and then another one would go over it.

[iron bobcat]

I agree, that it's not ideal and I'd like to shift to a better solution soon. I need the audio and door widgets to be drawn on tick.
Wouldn't the "remove all widgets" node counteract the stacking problem?

[minor lynx]

fun fact you cant set the type of a variable in a struct to world soft object lol

this is in a struct drop down

weird honestly you cant do it anywhere but it sets the right type if you right click and create new variable

[iron bobcat]

removed the link to tick for testing purposes. Same problem

[maiden wadi]

Where is that function being called from?

[karmic tree]

I don't know why the capsule is not following the character. I already enabled root motion but it doesn't work

[iron bobcat]

Isolated the entire thing, so there's no chance, that it's influenced by my "On tick" band aid solution

Also thx for helping out ^^

[iron bobcat]

First Person Character BP

[maiden wadi]

Hmm. Having trouble replicating this. Could you by chance create a new UserWidget with just a default textbox, and copy the event construct stuff into it. And change the CreateWidget to that? See if it still happens. Cause logically I can't see why it should behave like this.

[iron bobcat]

Will do. Give me a sec

New Widget. Completely empty except for this button

The only code in there

doesn't even show up 🤔

If I print out a string, it prints it though

[iron bobcat]

Which part of the character is it supposed to be following?

[maiden wadi]

That's odd.. Editor restart at any point?

I wonder if it's still there. Or if for some reason the event construct was called and then it was removed. Does Event Destruct run at all in that widget?

[dawn gazelle]

I've seen that happen - a widget is set up a specific way, and just doesn't want to work and all the logic is sound... Reset the editor... BAM, works perfectly.

[iron bobcat]

There is no event destruct set up in the new widget

Just restarted. Still there unfortunately

[maiden wadi]

Try running a print in Event Destruct. See if it prints.

[iron bobcat]

Going to assume, something completely different in my code is interfering somehow. I just can't imagine, what that would be

[maiden wadi]

Well, if EventDestruct runs, then something is removing it from screen, like a RemoveAllWidgets call.

[iron bobcat]

There is a remove all widgets call, but it goes off before the construct

[maiden wadi]

There's absolutely no where else that you've used a RemoveAllWidgets call?

[karmic tree]

Pelvis

[iron bobcat]

No. They're all disconnected

[iron bobcat]

Did you try attaching it to a socket?

[maiden wadi]

I'm at a loss then. I've never experienced that behavior personally. But EventDestruct definitely should only run when it's removed from screen. I don't know anything that removes widgets from screen besides manually removing them from parent, remove all widgets, or opening a new level.

[iron bobcat]

Hm...... thank you for spending so much time on this. Will let you know, when I eventually find that elusive mistake

[iron lodge]

In my game, I want to spawn two different types of enemy at two different locations, but I don't know how to do so. Here's the blueprint I have for spawning the enemies (it's found in the Level Blueprint), what would I add/do for the second type of enemy?

[maiden wadi]

Possibly just a random int in range and switch on it?

[dawn gazelle]

Just make sure to set the max range to the # of different options -1

[iron lodge]

ooh that could work

but what about my want for "enemy A" on spawn A, and enemy B at spawn B?

[dawn gazelle]

For something like that you could create an actor that manages the spawning.

[maiden wadi]

@iron lodge New function.

[iron lodge]

I want to make it so that if the player touches either of the enemy types, they will take the appropriate damage. However, I can't make it so that the player detects both types of enemy. is there any way to make it so that the "Event Hit" works with both types?

[trail condor]

I'm making a pop-up that appears after pressing a button in a widget. The pop-up is a widget blueprint. I don't want to put any buttons in this pop up, but I want it to consume the player's input, and then disappear. Currently, the focus stays on the button that opens the pop-up, causing additional ones to open

is there a way to set keyboard focus to nothing?

[earnest tangle]

Not sure off the top of my head but maybe you could just check if the popup has been opened and just not open additional ones until it closes?

[trail condor]

that would solve part of the problem, but it also seems that the button consumes my input, and I need it to be consumed by the player instead, and then sent to the pop up. I have the sending part working fine for anything except "enter" which pushes the button again.

[dawn gazelle]

Connect your event hit to the top cast, and then connect the cast failed to the bottom cast. Should work so long as the EnemyCharacter is not a child of ListenerCharacter

[iron lodge]

soooo. . . like this?

[dawn gazelle]

Yep

[iron lodge]

IT WORKED! I added a delay so that a light brush wouldn't insta-kill the player, and it works perfectly. thanks a million!

[trail condor]

I think my second question is more what I was after:
When working with UI, is there a way to set keyboard focus to nothing?

[dawn gazelle]

Are you trying to make a key binding system?

[trail condor]

lol... that obvious, huh?

[trail condor]

I'm like 90% done, and this is the last actual hiccup.

it's working with everything but my "confirm" buttons

[trim matrix]

hey is anyone here good at blueprint?

[slow zealot]

Hi, is there a way to change the selected background color for a textbox in UMG or C++? The multi-line textbox has this but I couldn't find it in the textbox

[trim matrix]

@slow zealot the color of a blueprint box?

[slow zealot]

I mean this

[trim matrix]

@slow zealot uhhhhh have you tried looking in visual settings?
