[formal parcel]

you mean, events?

well yea, widgets are pure trash in UE

surprised they didn't fix em tbh

[ionic raft]

Player is fine that way but widgets... kind of hate input

[formal parcel]

so this may be ridiculous but...

write your own input handler for UI?

then you could fire events for right left etc and the currewnt active UI could handle that logic

but yea thats a mess

[ionic raft]

I mean if I had more time i'd do that lol. For now I'll just do the jankiest way I guess

[formal parcel]

hey actually man

check the documentation, they might have some prime number silly math going on

it might be a simple in-line calc to get the button

[balmy vessel]

random question, anyone know why when i add an event, it spawns so far away from everything else? the bottom left one is something i just added

[tame pecan]

no, and there doesn't seem to be any decent fix

[red grail]

@formal parcel I'm currently looking through my character bp and thinking about what would better fit into the controller we made. Would all the character's individual cameras be better placed within the controller as a "one main camera for all" type of thing? I have a toggle between first person and third person perspective as well as a line trace off of those cameras that change crosshair color depending on if I can interact with the actor that I'm looking at. Is that something better placed in the controller? (Also if I'm bothersome, please let me know and I'll stop! 😄 )

[formal parcel]

nah you're fine man, the cameras I would keep on the character itself, but the activation of said cameras should be in the PC

but you're getting the idea, just think about what "domain" actually owns functionality

the cameras are owned by the characters IMO because their positioning and angles and such are determined by that character

i'd imagine a goldfish would have a different camera config than a helicopter

and those cameras would be anchored to different components and such... so its smarter to have the player controller request a certain camera, and the character itself implements that

[red grail]

So the toggle between first and third person should be within the player controller right?

[formal parcel]

yep

every single bit of input processing should be in the PC

[red grail]

As a function that I can call I assume

[formal parcel]

yep

well really the PC would prolly get the raw input event

and then decide what to do with it

lemme do a paint for you so its clear

[red grail]

In the event graph: Press hotkey -> function?

Hmm, that would apply that to literally every character tho

[formal parcel]

@red grail

[faint pasture]

I mean what's wrong with handling pawn-specific input on pawn GTA Style?

[formal parcel]

because its not pawn specific, read more

sorry for rudeness :/

my b

this is just general good OOP design

[red grail]

In case of the toggle between first and third person, if I'd want that on literally every playable character, I'd then put it in the controller, but if I for example didn't want it on one of them, I'd be better of with putting it in the characters right?

[formal parcel]

naw you would still put it in the PC

just do the logic of when it dont apply

[red grail]

How would I exclude that one character?

[formal parcel]

you may have all sorts of conditions

you could do it by type

just make a simple function "canUseThirsPerson" or whatever

then when they hit the input for switching, you run whatever logic you need to determine if they can, and if they can then you dispatch it

and if not, you dont

then you dont need to write camera permission checking code in every character

DRY principle - dont repeat yourself

[red grail]

Would interfaces be a good use of that?

[formal parcel]

perfect use

i didn't want to bring them up but in fact that is the ideal way

[red grail]

Like, put a thirdperson interface on the ones that I want to use it on

[formal parcel]

or just a check in whatever interface on each character .. "canUseThirdPerson"

then your PC can just call the interface on the pawn

and then you can do much more complex logic on the pawn as well to determine if it can use third person

but then on those that straight deny it just "return false"

[red grail]

This is so difficult to wrap my head around

[formal parcel]

software engineering aint easy

its easy to write bad code

its hard to write maintainable code

but proper architecture goes a long way to avoid spaghetti

[red grail]

Yeah, earlier today I ripped out a huge chunk of horrible code that got replaced with a simple interface lmao

[formal parcel]

but yea

interfaces are really the key to this type of thing

you have similar functionality but implemented differently between different type... textbook case for an interface

[faint pasture]

So you would do GTA style walking / driving mechanics by handling input in the PlayerController vs in the pawn? That sounds ass backwards. If the pawn is being switched around in gameplay I just put the common inputs in PC like Pause.

[formal parcel]

well I'd have a manager for sure, and then prolly delegate to vehicle and pedestrian controllers based on the situation

[faint pasture]

That's what the input stack already gives you.

[formal parcel]

i'm not gonna argue withj you adriel

[red grail]

It probably doesn't matter for smaller projects with an easily manageable amount of characters, but I'd imagine the more complex things get, the better it is to use the controller

[formal parcel]

you dont even know what we're really talking about or the context of the last 2 hours

@red grail correct, which is why I wasn't going to bring up interfaces in the first place... practical vs ideal and all that

but as a purely educational thing i explained it a little deeper

[red grail]

Well I had to use interfaces already so I have a rough idea, I'm just really surprised that I managed to connect atleast that somehow lol

[formal parcel]

well, you stumbled into the right solution 🙂

but yea, just in general any time you're going to make a handler or something, give it a thought to what really owns it, and where does this code really belong in my heirarchy

save you from massive headaches and bugs down the line

[red grail]

Is this right? Basically do the function only if X interface is equipped

within the controller

[formal parcel]

well the rule about interfaces used in logic like this is they must be implemented

so its not so much about does my pawn implement this interface, all pawns will implement it and all methods in it

[remote meteor]

the move input action doesnt really matter if its in pc or character

[formal parcel]

here we go again

[remote meteor]

unless you need to check whether you can move or no

[minor creek]

its 10 seconds right?

[remote meteor]

or such other checkings

then you select a suitable place to do it

[remote meteor]

yes

[red grail]

You talking about the resuming movement after pressing resume?

As in, I could have done that with a function within my character, completely ignoring the whole player controller stuff?

Or idk, I'm not sure what you mean

[minor creek]

any idea only one target point works for spawning?

[remote meteor]

menu inputs should be still in player controller

since it has nothing to do with character specific

[red grail]

I don't think I get this part

[formal parcel]

all the pawns will implement the interface and the method in it "canUseThirdPerson"

so the check isn't "does implement interface", its just... call that method from the interface

as they must implement it, thats the point of an interface

[red grail]

But why do all implement it? If I only put it in one of the character's bp and not the others?

[formal parcel]

think of an interface as a contract, implementing an interface is saying "i promise I will implement all methods within that interface"

[red grail]

Yeah, but if I have character1 BP with interface and character2 BP without interface, why do both implement it?

[formal parcel]

you're not understanding

[red grail]

Or are you putting the interfaces on the controller itself?

[formal parcel]

interfaces are separate concepts

they are their own entities

they dont go ON anything

they are defined, and classes can implement them

[formal parcel]

the situation we're discussing is that the characters can all implement this interface

[red grail]

We are talking about this right?

[formal parcel]

we're talking about the basic OOP programming concept called an interface 🙂

not just that dropdown

[red grail]

Oh ok, I was specifically talking about these interfaces

[formal parcel]

those are the same, yes

so interfaces are entities

paint to the rescue, one moment

[red grail]

haha okay 😄

[main wigeon]

Hey! Im trying to turn render custom depth on and of when entering a triggerbox. Nothing seems to happen. Can anyone take a look and see what ive done wrong potentially?

if I disable/enable the boolean manually prior to starting it does show/hide

[formal parcel]

alright

@red grail

this is the point

look carefully

[frozen moth]

Hi. I have an issue with building light of an procedural generated location. I have two similar projects, in the first project I test, then export to the main one. When I tried to build light in test project, the following error appeared. But at the same time there are no errors in the main project with the same geometry. All meshes & light in movable mode. How to fix this?

thanks in advance.

[formal parcel]

@red grail notice in the implementation we dont care about the type, we're calling functionality by the interface... this way every pawn we have can determine in their own way, and this same technique can be used for any functionality that is similar between different types of objects

without having to repeat a bunch of code

and you also then dont need to check a bunch of object types all the time

[red grail]

I'm trying to replicate that, do I need the first bool as an input or output?

[formal parcel]

what function is this?

[red grail]

Just a blank interface

[formal parcel]

its an output

[red grail]

Called it CameraSupportInterface

[formal parcel]

perfect

you dont need inputs for this so dont put em

its just one bool output

so the method signature is: bool Name();

[red grail]

Now, do I put that interface on the controller or the character?

[formal parcel]

the character will IMPLEMENT the interface

but for UE i guess thats putting it "in" the character

[red grail]

Idk, to me it looks like I'm assigning the interface to the character I want

[formal parcel]

yes

you should be able to assign the same interface to multiple characters

(all of them)

[red grail]

Yeah, but whats the point of putting it on a character that doesnt support the toggle?

[formal parcel]

so that you can call it in the implementation without checking the type

see the highlighted part of my image?

[red grail]

With type you mean which interface it is?

This node?

[formal parcel]

lets go private channel

[mild moon]

Hi guys, how i can make a painting system like this?

https://www.youtube.com/watch?v=thS9nuea8v8

[sleek kite]

Hey, anyone that would be able to spare 5 mins of their time to help me? I'm running out of ideas. A system that made logical sense to me is somehow not working and I'm not sure what else to try.

I have a global anim system for movement with added weapon pose layer blend on finger bones to simulate grip from weapon anim but to retain global movement.

Since we've had an issue with consistency and transition out of montages, I decided it would be big brain for me to just get hand_r transform both on global idle and custom idle , and from that calculate the fabrik IK offset I need for my weapon blueprint.

My first attempt

Inside AnimBP I print string and copy transform of hand_r on default global animation, then save that and get a transform of hand_r on custom animations. Then I simply custom transform (loc,rot) - global transform (loc,rot) = Anim Offset for Hand_R

I obtain the bone transform using - Get Socket Transform (HandTrack) --- Break Transform --- Transform to Bone Space (root)

This worked okay, was able to add the offset and make one of my weapons work correctly. Then I noticed I need to do the same for my Weapon bone so I do the same.

This seemed to work reasonably ok, but it was messy and seemed to have some issues on other weapons.. so I tried this

Second Attempt
I made a blueprint with my rig to avoid having to use AnimBP.

To get my offset I do the following

Play Global > Get Transform > Set Pos and Rot as var > Play Custom anim > Set Pos and Rot as var > Calculate Difference = Offset.

Now, this seems to work perfectly for only one of my weapons, but doesn't work for the rest.

Can't wrap my head around this. Any idea why this shouldn't work? It's just basically getting the transform difference between anim A and anim B.. applying the difference as offset should make it work.

Sorry for the long message. ❤️

First Attempt in Anim BP

Second attempt in BP Actor

[rain egret]

i am having issues with some weird stuff.
to clarify:
-each vertice has a "node" and a scene component assigned to it
-if i click on a node a gizmo is created at its location.
-inside the gizmo i plan to create events that fire depending on how i drag it around, as of now i am experimenting with the Z part only
-i want to set the location of the underlying vertice and set it to that of the gizmo (to change it if i drag the gizmo around)
-the mesh is scaled down by a factor of N

now the result however is:
-blue marks the point where the gizmo is supposed to be, but for some reason it goes to the red arrow instead

[vital aspen]

does anyone here know of a unreal engine 4 book that can teach inventory systems.

[sleek kite]

Hey, what kind of inventory are you trying to make? There is a lot of resources on YouTube

[sleek kite]

is that name a reference to Generation Kill? 👀

[vital aspen]

The 1 system I have now is an object related inventory system, It all works. Just the guy that help me set it up screwed me on the last part of it. The On Drop. It's the only thing I can't get to work. and you tube is a joke on inventory systems. sense everyone tells me to stay away from them

[kindred pier]

Trying to use view target, and have it ignore the player actors, is there an easy way to do this?

[vital aspen]

@sleek kite Ah no it's not.

[tawdry surge]

The reids channel one is actually pretty good. In general youtube tutorials aren't best practices, so you just need to look around

[faint pasture]

#animation might have better luck

[faint pasture]

What's your drop look like right now?

[trim matrix]

how can I start a timer when a boolean is set to true?

this doesn't work

[dawn gazelle]

start the timer when you set the boolean true. Use set timer by event or set timer by function.

[trim matrix]

where do I put that

Im going back and forward in the event graph and in a fonction

[dense mica]

Where vector * float pin went

[trim matrix]

?

[dense mica]

UE5 seems to be removed multiplying vectors by floats

Due to that double migration

[icy dragon]

Isn't UE5 math nodes getting more universal?

[dense mica]

Probably, but UX going worse for sure

You have to right click and convert vector pin to float manually

And if you plug the output pin to somewhere it becomes vector again

[gentle urchin]

Was hoping widcard * wildcard untill something compatible was plugged in

[dense mica]

Its difficult to type literal values :/

Anyway, classic

[tawdry surge]

It auto converts if you plug the pin in

[ornate trail]

noticing sometimes drag and drop widgets are set to not visible when the operation triggers 'On drag cancelled'. usually with just a small set of clicks within the panel which somehow doesn't register as a drag. Anyone encounter this?

[gentle urchin]

When doing vector*real?

[tawdry surge]

All math nodes convert float to double by default

[gentle urchin]

But does it accept non-matching types like that?

[tawdry surge]

Real type was removed after the preview

[gentle urchin]

Double or not

[tawdry surge]

Yeah

[gentle urchin]

Then thats updated since i tried, oor i dragged the pin the wrong way 😅

[tawdry surge]

Just connect the pins

Real was changed back to float after the preview version too

Now it just picks single or double precision

[gentle urchin]

Sad, i prefer real :p

[tawdry surge]

It's just confusing to make up a new type when float and double exist in c++

[gentle urchin]

True that, im just more familiar with it from my dayjob :p

Plc programming

Real all the way

[quiet shuttle]

How would I go about making a line trace that ignores a bunch of actors of differing classes?

[kindred pier]

you could make an array of those actors and toss it into the ignore actors part of the line trace node

one example

[trim matrix]

doesnt work

[faint pasture]

What's the use case? Might be a better idea to have a custom channel for whatever tracing you're doing, depending.

[trim matrix]

how can I start a timer when a boolean is set to true?

as soon the bool is false the timer resets

talking about the hit boolean

[kindred pier]

I was unaware of this, would this be useful is say, the camera, and visibility of a spline mesh were set to no collide, would a custom channel be able to collide properly?

[faint pasture]

What are you trying to do or implement?

[kindred pier]

trying to make a reusable set of bp code that can take in any chosen actor via line trace (but that doesn't grab everything, so I've been messing with view target to no success)

[trim matrix]

anyone?

[kindred pier]

well any actor visible to the literal human player

[faint pasture]

Do you only want the one chosen actor to block the trace, everything else ignore?

[faint pasture]

I'd use the visibility channel for that, but you're still a bit unclear on what you're trying to do.

You have 2 channels out of the box, camera and visibility

You can add more if you want

[kindred pier]

I'm trying to grab only the first actor hit by the trace
Both seem incompatible with spline meshes without the person having to do some editing on their end, and I'd prefer it have an out of the box thing for the splines (which auto ignore those from what I can tell by default)
Does seem like this new channel thing might be worth checking out

[undone surge]

can someone help me understand the diff bw a variable and a balckboard key ?

[faint pasture]

So why do you have to ignore things? You're still not saying what game mechanic you're trying to implement. Do you want to hit the spline mesh or not?

[kindred pier]

I am trying to have the player be able to select any object in the world with a widget button and have that be the selected actor which info is funneled into various other things

[faint pasture]

So why do you have to trace?

[tawdry surge]

@undone surge a blackboard key basically is a variable. It's just assigned on the blackboard

[kindred pier]

Unless I am missing something it seemed the best way, well view target seems alright too but I am still working on learning more about the camera stuff

Is there a better way to get what actor the current player is looking at/what is in front of them?

[faint pasture]

That's the first time you've mentioned trying to do that, you said you're wanting to select with a widget button.

Do you mean you go into some select mode with a widget button? Like an RTS?

[kindred pier]

That was poor wording on my part, I just use the widget button to trigger the line trace to get the actor info I am looking for

[faint pasture]

OK so yeah I'd either use the visibility channel or make a custom channel, depending on how much selection and other visibility stuff your game is made up of

have stuff you want to be able to select / block selection block Visibility or your custom channel

[kindred pier]

Ahh thanks! I will check into these custom channels 👍

oof seems custom channels aren't out of the box friendly, might look more into view target

[raw orbit]

is it possible to somehow 'project' or simply show a a copy of a widget? idk how to explain. basically trying to do a dark souls type of inventory where your main hud shows your currently selected quickslot item but the quickslots themselves are separate

[tawdry surge]

What do you mean not out of the box friendly?
Create a custom trace channel in project settings, set the collision on the actor, done

[faint pasture]

What does view target have to do with any of this?

[faint pasture]

Widget within a widget

[kindred pier]

can get the spline actors just fine, when it's not colliding with the player in some, though it doesn't have atleast an easy way to filter actors out of it

referring to the get view target node

[faint pasture]

OK please just spell out exactly what you're trying to do. You keep talking about spline actors and view targets and line traces and tracing in the players view direction but it just sounds like a mess.

[kindred pier]

I am just trying to find a way to get what is in front of the player, or what the player is looking at, that can pick up skeletal, static, and spline mesh actors
Not every game has their spline mesh actors set up to work with camera/visibility
so I was looking into get view target instead of line trace as it seems more consistent
Though it hits the player itself in some projects and unlike the line trace node, it does not have an ignore actors thing to plug into

[faint pasture]

I've never used "Get View Target" but "Set View Target" just tells the camera manager what actor to look at. "Get View Target" probably just returns your pawn.

You just want to do a line trace from your camera position to camera position + CameraForward x SomeNumber, and trace on whatever channel you care about. Or you can trace by object types or whatever.

[slender idol]

Hey is there any way to check the hit object channel on a hit event?

[faint pasture]

I would use Visibility if it's meant to approximate what's visible

[faint pasture]

Like getting the "why" of a hit?

[kindred pier]

thanks I'll check this out, I think I was misunderstanding the get view target node

[slender idol]

Yeah, instead of handling it through hit actors, I want to know which channel triggered the hit

nvm found it you can do it like this

[quiet shuttle]

Right now im using the line trace to place down actors in the world, but I only want the line trace to hit "ground" and not any other actor

[faint pasture]

Does Z vary or no?

[undone surge]

these two bascially do the same thing right ? except for the extra options

[wicked osprey]

Guys, I wanted to ask you, is it necessary to do a clear and invalidate timer by handle if the timer is triggered only once? He's not looping

[gusty shuttle]

If it's a one off shot, then it might not be bad, unless you needed to call it again

[wild jetty]

Trying to get some text to switch between two options, i've got a function for this already that's working fine on my 'Create Lobby' widget, this toggles between LAN/Steam without issue.
Yet once I'm on my lobby menu, the text to switch between Deer/Hunter is just blank and doesn't show anything... Any tips on where the issue may lie?
Function is exactly the same, the variable is set as a boolean in my game instance, the function get's this variable and sets it to branch between deer/hunter then return it and this is then set within the lobby widget graph.
I've no idea why the text is just refusing to show though during tests?

[cobalt gulch]

how could I set a lobby of 10 players to be on 2 teams

[dawn gazelle]

Can you show the code that is calling "Toggle Deer / Hunter P1"?

[cobalt gulch]

Should I just set 1-5 to blue and 6-10 to red?

[dawn gazelle]

Also, Game Instance and its variables don't replicate, so may not be the best place to store that value if you want it replicated.

[faint pasture]

Isn't that GameMode?

Er nvm

[dawn gazelle]

GameMode too 🙂

[faint pasture]

I was thinking GameState

[wild jetty]

I managed to get it working, Although I'm not 100% certain what the fix was.
It seems somehow I managed to create a different... type of function? Somehow?
The functions at the bottom of this list are the ones that didn't work.
After I copied my LAN/Steam function from my other widget and changed it over to the correct variables then set this new function as the binding, it's now working fine.
I'm not sure why those bottom 2 functions are a different colour, but it meant they weren't working

[wild jetty]

If this is the case, where would be best to store this variable so it can replicate properly for both players in my lobby?
Sorry I'm still really new to use and trying to learn from other tutorials

[dawn gazelle]

Typically playerstate would be the place to replicate information about a specific player.

As far as why the text isn't updating, that looks like you're using function binds which is fine. So long as you've made sure that you've selected the appropriate function for the field, then it should theoretically be working.

[wild jetty]

Ok I'll take a look into the Playertstae and getting it working with this, thank you 🙂
As for the binding, I'm really not sure why those 2 functions are different colours to the others, I created them the same way I always do, yet the binding just caused my text to not appear...

Either way, it's working for now, I appreciate the help!

[faint pasture]

@wild jettyIf this is a game mode where one player is a deer and another is the hunter, just have on GameState something like bool Player1IsDeer or Playerstate Hunter or some other SINGLE source of truth as to who's who.

If there's one Hunter and many Deer, just have a Playerstate variable on GameState called CurrentHunter or whatever.

[small halo]

https://gyazo.com/75cbf8750dcf4557b9ae515560ba39d3

how do i reset the players control rotation?

[faint pasture]

From where?

[small halo]

back to default

from the player looking at the ai

back to default

[faint pasture]

Just set it to 0,0,0

[small halo]

i did so but it didnt work

[faint pasture]

Show your entire logic chain

[wild jetty]

Thanks Adriel, I'll give this a look!
Trying to work it all out from fresh to slow going.

[small halo]

https://gyazo.com/f839872b49731a137f844a46ba83bfc1

[wild jetty]

Thinking on this though... Would I be able to do as you mention and STILL give players the choice as to who plays what? 🤔

[small halo]

I then use simple ai move to but when the player is running (fp) he is looking to his side and not the direction he is running to

[faint pasture]

What's the setup, is it 1 vs many, many vs many, what?

[wild jetty]

So far, just 1v1 until I can get more comfortable and know that it works 100%

Then I'll add more as time goes on

[faint pasture]

But I mean how does the team setup work, is it like tag where there's 1 person of interest, or is it just like any other pvp game where there's 2 roughtly equal teams, or what?

[wild jetty]

2 equal teams, i may add in a 2v1/4v1 mode down the line, but for now, just the 2 teams, 1v1

[faint pasture]

Oh ok then either store some team state on each playerstate, or in gamestate have 2 team lists

[wild jetty]

Thanks 😁 I'll take a look to see what info I can find on specifics on how to go about doing that

[faint pasture]

I'd start by just slapping a boolean on the PlayerStates bIsHunter

[wild jetty]

Recommend 2 different player states? (I'm really unsure if just 1 is ok or not 😅 )

[faint pasture]

No, just a variable on your PlayerState

The State of the Player is whether or not they are a Hunter

or rather, whether or not a Player is a Hunter is a part of that Player's State

Player XxX420Sephiroth68xXx is a Hunter

[wild jetty]

Old Xbox 360 username? 😛

[wild jetty]

Ok boolean added, I'll swap things around in the functions to pull from the playerstate instead to decide who's hunter/deer

[brazen spear]

Hey all! I am having a super big problem as I am creating an endless runner game following UE tutorial, I am trying to get the game to restart when the player dies but I keep getting this error : TravelFailure: ClientTravelFailure, Reason for Failure: 'Failed to load package '/Game/ThirdPerson/Maps/UEDPIE_0_ThirdPersonMap''. Shutting down PIE.
What does it mean? I have gone on multiple forums and am still super stuck 🥲

[spark steppe]

how do i unroll an rotator while keeping the yaw/pitch point in the same direction?

[wild jetty]

Sounds like when you're respawning it's trying to load a map that may not exist? Check your maps folder to see if it's there

[brazen spear]

there is a map called ThirdPersonMap , I dont know why the error says UEDPIE_0_ThirdPersonMap though?!

what is UEDPIE_0 haha - I am so confused

This may sound silly but should I change the map name to UEDPIE_0_ThirdPersonMap

[wild jetty]

Unsure on UEDPIE_0 but PIE is when you're using the engine itself to test the game. Maybe try launching as a separate application?
under the Modes try your PC name, or 'Standalone Game'

[brazen spear]

Omg you are right! On the Standalone Game it respawns!!

I am curious why that is?!

[faint pasture]

@brazen spearYou got some dangling redirectors hanging around? Fix up redirectors in the content folder.

[wild jetty]

Unsure, with my own game I always have to run it as a standalone game or via my PC being in the list because of running Steam, I'm not sure in your case though

[faint pasture]

https://tenor.com/view/what-confused-cringe-idk-awkward-gif-18153340

In UE5 how do I change the Inputs/Outputs of a Blueprint Interface? As soon as I add an output everything is grayed out and i can't change the name or type of the ouput or inputs?

Nevermind i found that I must select the function name from the right panel....

[kindred pier]

edit: guess more of a c++ thing so I'm moving it

[wicked osprey]

Guys, can I return values from function what i call from timer? If no, which way can i use?

[quiet shuttle]

No. Ground might but I don't want to stack actors

[faint pasture]

Then just have the terrain or whatever block the trace channel and nothing else.

Or if it's totally flat you can just use a line plane intersection

[quick lark]

Is it possible to use the camera shake blueprint to drive the transform of any scene object instead of the camera?

I'm trying to get a satisfying shake on the cockpit of a mech every time it takes a footstep

[gritty plover]

Hey... This Begin Overlap node is firing every single frame that the 2 components are overlapping, and not just when they begin overlapping. What's the dealio with this?

It's also firing the end overlap node every single frame as well.
But it's literally just one component inside of another component. Nothing complex. Nothing ridiculous going on. Just... All there is to it.

[cobalt gulch]

How can I fix stretched textures which are scaled

[thin panther]

Uv unwrap properly

[cobalt gulch]

I meant when scaling in ue5

[thin panther]

Ah i take it you are using static mesh cubes or smthn as walls

[cobalt gulch]

Yeah

[thin panther]

Yeah try to use a wall mesh

Can probably do somethin g with world aligned materials

Ir if its a prototype dont worry about textures

Is there an event that triggers for when a widget's button gains keyboard focus?

like on hovered with mouse

[mellow folio]

I think that is an override, look at the function overrides

[round moth]

So should I put stuff like player experience in the game instance, and health since I want those to carry over between levels

[winter kettle]

is there a way to know if a blueprint struct has another blueprint struct as a parent?

[mellow folio]

That could work, but it would not save anything between games. You can use save game objects

[thin panther]

just have ti save from the game instance as well

[rain egret]

i am using a timeline to drive add local rotation to make the ship tilt left and right a bit, tho it oddly always tilts stronger to one side than the other

i already looked at the values and it should tilt equally on all sides

[fervent jolt]

Hey, I am making a game with a level editor. to save both the blocks and race times from each level I'm making a new save slot for that level. Is this a foolhardy path fraught with peril?

[lucid lynx]

Is there a way to interrupt SetViewTargetwithBlend? I'm using it to transition from one camera to the next, but I'd like to interrupt it in some cases.

Calling SetViewTargetwithBlend again with no blend time does not seem to snap the camera to the new target.

[wise tide]

I noticed I can do some things on construction. So I used to have my material apply on play for my display model (apply from parameter/variable).

Now though I put it on construction and it does it in the editor, however setting the opacity doesn't seem to change in construction. Is that a begin play exclusion or something?

How do I know if something can be done in construction or if it has to be on play

[quiet abyss]

(Hope this is an appropriate channel. Please correct me if not)

Anyone feel like helping with maths lol? I've gotten this far but alas my brian has turned into mush trying to figure out how to solve this.
https://blueprintue.com/blueprint/ye34vyll/
Context: I'm using this to control 2D eyes via a material, this makes the eyes follow the player. I'm projecting a vector through a plane and finding the intersection point, then doing some calculations to convert the point to a 0 -> 1 range, with 0 being the left-hand edge of the plane, and 1 being the right-hand edge of the plane.

The issue is, the object has to be rotated between 0 - 180 on the z axis in world space for this to function properly. If I rotate it anywhere beyond that, my 0 -> 1 range becomes flipped so the x location of the eyes become reversed.

Math logic isn't my strong suit lmfao. Can someone by chance help me figure this one out?

[gentle socket]

Is it possible to create something like an "instance" of an Object blueprint with certain values for the blueprint's variables before runtime?
Similar to how you can create Texture "instances" and assign these to blueprints with Texture variables.

[quiet abyss]

You can set variables within the blueprint to instance-editable, would this work?

[gentle socket]

Not entirely

For reference I'm trying to make something like a texture but with some extra functions/variables

But if I then give a different blueprint such a class I don't have a default variable to assign to it

And you can't define an instance in places like this

[gentle socket]

For a simple effect I think you could just project a unit vector from the position of the eye to the position of the viewtarget onto the plane of the 2D eye (centered at the position of the eye). Then clamp it to the bounds of the eye and scale it with some factor

This projection is then this:
https://www.maplesoft.com/support/help/maple/view.aspx?path=MathApps%2FProjectionOfVectorOntoPlane
With the normal vector of the eye for n and u the (normalised) vector from the eye to the target

[quiet abyss]

Pppf yup theres no way I'm not overcomplicating this. This sounds like a much simpler approach, thank you! I'll give it a shot

[round moth]

like saving and loading

[rain egret]

wtf why isnt this working, the timeline is no magic, yet it cant for the life of it create a uniform tilting , it always tilts more on side

it shouldnt be able to do that, why

[fervent jolt]

seems to me it would be a issue with either the ship object origin or object relative rotation vs world rotation

[rain egret]

all the rotations from the ship are 0

its start rotation is zero

[unreal marten]

so I'm trying combine all of my UI widgets into a singular HUD and everything seems to be working except the HP bar, the current/max health values in the same BP show up just not the progress bar, any ideas what I'm missing?

[hollow gorge]

show code or rather BP

[gentle socket]

Right, so one way I could do this is to make the Object "instances" child blueprints of the original blueprint with different default values.
Then in the blueprint which has the an Object variable you'd add a second variable with a class reference which references these child blueprints.
The Object variable can then be instantiated from one of the child blueprints.

That seems rather convoluted. Surely it must be possible to create multiple instances of a class?

[unreal marten]

this is the health ui widget, it works fine in itself but when added to the hud ui as usercreated widget, only the set text portion is working the progress bar is non existent

you can see placeholder text but the progress bar doesn't carry over

[zealous moth]

@quiet abyss why not use dot product?

[unreal marten]

and now I feel dumb, increasing the size of that box a lot fixes it but not sure why the text worked right out of the gate

[elder ruin]

Can anyone in here help me out with saving to a .txt file in game? I'm wanting to have a bunch of functions that can actively update files to be accessed via another program, but there doesn't seem to be any native features for writing .txt files.

[pine trellis]

does anyone know how to merge all these materials into 1 for a character skeleton mesh???

[quiet abyss]

Good question. Mostly because math isn't my strong suit 😅 I did solve my issue though! Instead of using world-space coords, I'm using local space.
I'll look into dot products though, chances are it'll simplify what I'm doing even further!

[zealous moth]

@quiet abyss I use dot products to determine angle and rotate in response until it is around a value of 1

@pine trellis export mesh into Maya and redo the UV mapping into an atlas

@elder ruin I thought there was a plug in like that in the marketplace

[unique harness]

There are native features for doing this. I'm just not sure if they're exposed to BPs

[elder ruin]

I grabbed EasyFileManager, which was supposed to; but as of yet I've only been able to append files, not rewrite them.

[elder ruin]

Any clue if it's possible to expose them to BP?

[unique harness]

yes of course

I don't blame you 😛

[last walrus]

do we have something like "get character as number" but vice versa? like "int to character"

[silk cosmos]

https://streamable.com/ajl1oe

How would I shrink my capsule component for a crouch without the player getting pushed into the ground?

[earnest tangle]

Have you considered using the Crouch function that's already in Character/CharacterMovementComponent?

[silk cosmos]

that snaps the camera down too sharp

looks bad

[earnest tangle]

Right- I have a workaround for it which just lerps the camera :D But if you want to do it manually just copy what it does, which is moving the appropriate components up/down

[silk cosmos]

dang. i was hoping thered be some way without coding lmao but thanks 🙂

[unreal marten]

trying to get this to work, the start game function works fine in its original blueprint but when I try to reference it in the playercharacter I get this error and I'm not sure why

[dawn gazelle]

You mean something like this?

[dawn gazelle]

This is a variable and you need to populate it with a reference to the actual instance of whatever the variable type is.

[last walrus]

"make literal ..." just lets you input some value without creating a variable

so... no, not what I'm looking for

[unreal marten]

its currently set to the main menu ui BP which is allowing me to get the play button, or is it something else I need to do?

[dawn gazelle]

The important bit is the thing converting the int to the string.

[dawn gazelle]

That isn't setting the value in the variable, all you've done is set the variable type, not what is contained in the variable.

Eg. I can have a variable called "Integer" but its default value is always 0. Your "MainMenu Widget Ref" will always have a default value of "None" unless you set it.

[last walrus]

it just converts int to string

I want to do stuff like 1=a, 2=b, 24=z

[dawn gazelle]

Ah.

[upbeat rain]

Does the function "Get Bose Poses for Frame" actually exist? It doesn't seem to be accessible anywhere.

[dawn gazelle]

Don't need the literal int thing there... you can feed in whatever integer directly into the select.

[last walrus]

and... I need to specify every case
latin, cyrillic, hieroglyphs, numbers, special symbols...

theres a perfect solution
but I dont know cpp...
https://www.techiedelight.com/convert-int-to-char-in-cpp/

[unreal marten]

okay I understand you now, yeah I forgot to set the variable after creating the widget.. thanks mate!

[long whale]

hello, is they a way to change interpolation method of already imported curve table?

[limpid bronze]

why aren't we allowed to put delay nodes in functions?

[icy dragon]

Because delay is a latent operation, while BP function is not. BP function's expected to go all the way at once.

[deep elbow]

hello! tryign to script an editor utility widget to disable/enable collision on level actors (static meshes), nothing i do seems to actually change the collision when viewed via the "layer collisions" view mode, any thoughts?

[deep elbow]

a good way to think about a function is that the output of the function, ie whatever it is supposed to do, is going to happen all at once, and the result is what is useful, not how it gets there.
if you are using a delay in a function you are probably trying to "tidy" a blueprint or you should be using a macro if you want to re-use some code

[limpid bronze]

Ah okay.

[trim matrix]

Use Simple Collision As Complex

This means that if a complex query is requested, the engine will still query against simple shapes; basically ignoring the trimesh. This helps save memory since we don't need to bake the trimesh and can improve performance if the collision geometry is simpler.

Use Complex Collision As Simple

This means that if a simple query is requested, the engine will query against complex shapes; basically ignoring the simple collision. This allows us to use the trimesh for the physics simulation collision. Note that if you are using UseComplexAsSimple you cannot simulate the object, but you can use it to collide with other simulated (simple) objects.

Hi guys, how to toggle between them from blueprint in real time?

[trim matrix]

What is layer collisions view mode 0o?

[deep elbow]

sorry i meant "player collision".
i foudn the solution, just worded weirdly in blueprint nodes, "Set Collision Profile Name" set to NoCollision or Default works, then you just have to toggle visibility of the actor to get the viewmode to update, beep boop unreal gloop

[trim matrix]

Oh, you wanted to hide the actor and turn off the collision, I see

[deep elbow]

ah no, just disable the collision, but have it update in the collision viewmode like this:

but this works:

[unreal marten]

looking to make an interact prompt when near an actor, was hoping to have the prompt built into the hud and just hidden until near npc/invisible when away from npc, but even though the overlap events work fine I can't get the prompt to be set to invisible, and I don't think I should be creating the hud in the NPC blue print but I don't know how else to get and set the hud reference

would I be better off just creating and removing the widget separately from the hud?

[deep elbow]

have you checked what is failing? is the cast returning failed when ending overlap?

[unreal marten]

the checks are definitely working, but the set visibility nodes aren't doing anything at all

[surreal peak]

@unreal marten Where is the code from your image located?

You are casting to BP PlayerBase which sounds like you are in the interactable?

[tawdry mural]

set array is working like clear and populate ye?

[surreal peak]

Set Array sets the Array

Like, that's about it

[tawdry mural]

if i set it with 10 names first then with 5

it will have 5?

[unreal marten]

inside BP_NPCBase, it seems to work fine if I stick to just the prompt UI and add to viewport/remove from parent as needed, but not the hud visibility

[surreal peak]

Yes, it fully overrides whatever values were in it before

[surreal peak]

Why are you creating the PlayerHUD widget in your NPC

That creates one per NPC and all of them are different instances

Interaction systems make more sense the other way round

Interface on the Interactable Actor. Some custom Collision Channel on some Sphere.

Handling the overlap in the PlayerCharacter and not the NPC

Getting all required data for the Interaction via the Interface functions

And then accessing the HUD from the PlayerCharacter or its Controller directly (wherever you create the HUD)

[unreal marten]

I'm partially following you, I got the interact/prompt working now but I should move the interact function (HUD is already in BP_PlayerBase) to the player instead of the NPC?

okay it's moved out of NPC to Player, works well now thank you! how do I ensure it only triggers when overlapping with a specific actor type like BP_NPCBase? does it have to be cast at them?

[surreal peak]

Yeah the only thing in your NPC should be the interface and the implemented functions of it

[surreal peak]

No, theoretically all your Interactable Actors should have the same Interface applied to them

That's what you use to get the interaction type, like press, hold key or instant (e.g. pickup on the floor), as well as duration, name, if it's Interactable atm (maybe it's turned off or has any other requirement)

And lastly the functions to actually interact

Such as OnInteract which you call when you press your button

Each Interactable implements this function (as well as the others) and does whatever it should when interacting

E.g. a door opening, an NPC starting a dialog, a lever playing an animation and opening something

[unreal marten]

@surreal peak so if I had say BP_Actor1 and BP_Actor2, how would I set EventActorBeginOverlap to only trigger when overlapping with BP_Actor1?

[undone surge]

how would i reference a variable from my main 3rdpersonBP into my behaviour tree

[deep elbow]

add some mechanism in your bp that listens to the interface call that blocks new requests until the old one is removed

[fiery glen]

I believe it has to be present on the blackboard

[alpine ingot]

Hey! Is it possible to sample a vector field volume at a given location in space?

[icy dragon]

Is there a way to have some kind of failsafe or cancelling async load assets? Say, if the asset somehow took too long to load because of user's storage I/O is getting clogged for some reason

[low storm]

Anyone know if there is a way to do something like the following in blueprints?

   if (WarpyThingOne){
    DoWarpyStuff(input, WarpyNumber)
  }elseif(WarpyThingTwo){
    DoOtherWarpyStuff(input, WarpyNumber)
  }
}

//Case One, Does both
SomeFunction(Input, 5, WarpTarget, ADifferentWarpTarget);

//Case Two, Does WarpyThingOne
SomeFunction(Input, 5, WarpTarget, NULL);

//Case Three, Does WarpyThingTwo
SomeFunction(Input, 5, NULL, ADifferentWarpTarget);

[alpine ingot]

Yepp definitely. Exactly how you wrote it. Make a function with the inputs then use a branch node for if and use isValid node for the branch input

[low storm]

Oh, perfect! Thanks!

[jaunty jolt]

i need to convert a vector in blueprint to do this setMag thing of p5.js:
https://p5js.org/reference/#/p5.Vector/setMag
How do i do this?

It seems like it scales it up

[fiery glen]

source code of p5.js

  return this.normalize().mult(n);
};```

looks like you want to normalize it and then multiply

[jaunty jolt]

@fiery glen So this is a setMeg(20);

[fiery glen]

yep

[red fossil]

hey, ty for the reply. I got it though, I didn't need camera clamping after all

[pseudo pelican]

can line traces trigger on begin overlap events?

[tame pecan]

yes, if you tell them to?

[barren flower]

Whats the best way to organize a voxel grid in terms of data?

[opaque blade]

sparsely

[prisma tree]

In my 1st person game, how would i go about creating an effect of closing eyelids? Use the UMG somehow? or create physical "eyelids" that cover the camera?

[past hazel]

How can I make it so that the lines do not repeat and there is only one?

[opaque blade]

Texture size Y or X can be different, so 64xY and then have to adjust it to the width

But assuming this will be a road, World Aligned might not be what you are looking for tbh

[fiery glen]

probably a Post Process material that is like the vignette effect except it can interpolate the height of the vignette

[opaque blade]

you can utilize a postprocessing material for that

ie. a texture (grayscale) showing the progress of eye closing progress
and in your bp / camera modifier you interpolate to close / open

[scenic kindle]

how do i return the opposite value of a random float? (i.e positive -> negative, negative ->positive)

[marble tusk]

zero minus float should do it, right?

[past hazel]

I just want it to repeat on one axis

[opaque blade]

yeah then its fine with WordlAligned

if you have curves you won't be happy

Instead of doing a scalar to **TextureSize **either plug in a **vector **directly or two scalar with an append

[scenic kindle]

that's what i thought but the float could be positive or negative and i don't know which one. i need it to return the opposite value of whatever the value is

[opaque blade]

• -1 ?

[scenic kindle]

oh ya that might work

[opaque blade]

If it is a special "opposite" aka 0.6 should be -0.4

Use a Sign node and filter that way?

[icy dragon]

Set the texture wrapping to clamp, though FWIW might as well not doing it with world aligned mapping

[raw orbit]

any idea why this would happen when changing a character's anim blueprint? trying to make the dragon 'fly'. Nothing is wrong with the flying blendspace cause i can used it for 'walking' or 'jumping' just fine but when i want to swap movement mode to flying the dragon gets bent as if it decided to try out every pose in kamasutra at once

this is also a child of a 'template' anim blueprint, i have other flying creatures that work just fine

[icy dragon]

Call it the KS state.

[icy dragon]

Okay, just kidding.
Any reason for the flying not to be in the same animBP with different state?

[raw orbit]

lol. what you mean its all in the same anim blueprint sorta

anim blueprints are my bane i swear

the blendspace should work fine as far as i can tell

[stray light]

This is a place where we can ask for help with the blueprints yes?

[icy dragon]

Ask away

[stray light]

Lemme get my screenshots

So i am doing a project for school and im trying to make a small LAN multiplayer game in Unreal Engine with this

It used to work just fine on 2 laptops but now it no longer finds/joins the hosted server

And when looking at logs the return I get is

Warning: Script Msg: Attempted to access index 0 from array 'Temp_struct_Variable' of length 0

And I dont understand why

It works perfectly fine when connecting from 1 computer just when its 2 separate ones it doesnt work

[barren flower]

Okay so, sparse voxel octree, but, how do I store those things?

As in, should each voxel store its whole tree?

how do I probe a single voxel and find out which branch it exists in?

[opaque blade]

Each voxel is stored inside the octree
Octree is just an optimization for spatial subdivisions, so if there are no voxels in a larger area, you can get away with a pretty lowres octree bound

So you have an octree storing where voxels are

meaning here TL,BL,BR are 0-level octree sections

TR is subdivided 2 times where 3/4 are empty but TR,TL has elements in it

usually 0-level is also called 0 Depth, where subdivision is also called x-Depth

octree only helps you to early out of rendering / searches, so you don't have to sample everything which is empty

[barren flower]

Right but like, in practice, how are they stored

like are we talking structs here?

is there some custom data type for octrees?

[opaque blade]

There is an octree implementation in source, I would highly advise against implementing octree in BP

But yeah each cell is a struct

[barren flower]

Thanks very much!

[fickle dune]

How would you make character movement a condition for a branch? I want it so that you can only zoom in the camera as long as the character isn't moving I got the character movement out of the cast to third person node but not sure how to turn that into a condition

[onyx cypress]

thx

[tight schooner]

I've never used the third person template, so in lieu of someone giving you an informed answer... Is "character movement" a component? Does this component provide velocity data?

If so, you can check if velocity (vector length) is under some threshold to determine if the character is meaningfully moving or not

[tawny hedge]

you can use similar way of calculating speed like it's used in animation blueprints. calculate speed . if speed is 0 = not moving. There's quite a bunch of tutorials on how to calculate speed on youtube

[tawdry surge]

Get velocity, get vector length, vector length == 0
True will let you zoom only while idle

[fickle dune]

yes it is a component so take that to vector and vector to bool?

I don't see any other choice

sorry no that's stupid i don't know how to do it 😅

when the player sees another player next to the AI, it should look like in third person view

Hey, trying to keep a actor or paste it's values between scenes but unsure how. The setup is that there's a PatchEntry level that will pull .paks and once complete will load a level, however there's a actor in this level that reads Unity launch parameters (json) for the 2nd level and it has to keep those when switching.

[proper tendon]

if you're answering my question I understood about 0 things in that sentence haha

[dawn gazelle]

You can mark variables as "Exposed on Spawn" and "Instance Editable" which will allow you to set their values when they are placed in the world.

[proper tendon]

where can I do that?

found it!

[dawn gazelle]

Where you define the details about the variable within the blueprint.

I'm looking for a function, that disables all events / input within a widget (i.e.: Hovering over buttons etc)

yeah that's what i'm doing now, but i wanted to see if i could do it with just the widget (if you are talking to me :D)

[spark steppe]

yea i do, and i don't think that it's possible

as the component needs some "home" :>

[magic gate]

yup 😕

[remote meteor]

all the static mesh on the levels are made like that anyway

actor to house a component

[lilac storm]

hi is there a way to get an reference to currently using camera ? i bought a kit where is character got 9 differenct camera components and i want to get a ref to current camera at run time

[magic gate]

not sure if this is specific to my project, but 'get player camera manager' is the node that always returns the right camera for me

[unreal marten]

how can I get EventActorBegin/EndOverlap to only trigger when overlapping specific things? for example its triggering when overlapping power ups but I only want it to trigger when overlapping an npc

[magic gate]

you can adjust the collision behaviour

alternatively you can check when overlapping with what you are overlapping and choose to do or not do something with it (but this is probably a worse implementation since the collision still triggers)

[tribal kernel]

how can i change ue5 character for a mixamo

[unreal marten]

well I need to be able to overlap with either 1, but have different outcomes based on what im overlapping with which is where I get lost, for example here I can print string to see what's overlapping but I don't think class/display name will be helpful I need like parent blueprint or something? basically check for BP_Interactable vs BP_NPCBase

[magic gate]

you can use 'cast to ...' nodes to check which type the actor you bump into is

if the cast fails that means it either was invalid in the first place, or that it isn't of that type

so you can do 'Cast To BP_Pickup', and if that succeeds you know it is a pickup

casting actually gets used for filtering like this all of the time

[gentle urchin]

Thats why my suggestion wasnt really a good one. Would be overly complicated for very little gain :p

[unreal marten]

so if I needed a check for say pickup vs npc vs enemy would I cast them in a sequence?

[flint shard]

I'm trying to deploy the same app to multiple platforms, desktop, mobile, vr. What is the best way to spawn a different player pawn depending on the deployment platform. Right now I have an enumerator, one value for each platform I intend to deploy to. I'm guessing I can spawn a different pawn from the player controller? Maybe the level blueprint? What's the best way to do this? Is there an established practice?

[gentle urchin]

Override the spawn event in the gamemode, selecting class to spawn based on your enum

[flint shard]

Killer, thanks fam

[magic gate]

kinda, not a sequence node, but more like a chain

like this

with a sequence node, you'd execute all casts even if you have already found what you needed

[unreal marten]

got you so chaining them from each other will skip the other checks instead of checking everything even if it passes on the first check?

[magic gate]

yes

[surreal peak]

I want to add here that as soon as you have to do what warre posted, you are probably doing someting wrong

Cause that is usually where you have a simple Interface call

Casting to every possible option is in 99% of the cases bad coding

[pearl moth]

AttachTo: /Game/UEDPIE_0_TheHorizonMap.TheHorizonMap:PersistentLevel.TPC_C_0.CollisionCylinder' is not static (in blueprint "TPC"), cannot attach '/Game/UEDPIE_0_TheHorizonMap.TheHorizonMap:PersistentLevel.TPC_C_0.SpringArm' which is static to it. Aborting.

[surreal peak]

It kinda tells you what is wrong

[pearl moth]

SpringArm is movable

And if I set "CollisionCylinder" to static, the character wouldn't move.

Wait no, SpringArm is static

[magic gate]

i figured 😄

[unreal marten]

I think that's what you mentioned yesterday but I wasn't able to follow along, so I would check if the actor im overlapping can create an interface (like a shop or something?) and if it can then it shows/hides the widget? and if not then I don't need the widget to appear anyways

[pearl moth]

So?

[magic gate]

yeah I am interested now, how are you supposed to do it then? I was taught to do it this way

[surreal peak]

An Interface is not a UI

An Interface is a programming concept

[magic gate]

an abstract class

[surreal peak]

And Interface declares functions. You can add the Interface to a class, which then can implement those functions

[mental trellis]

Yes, but not because it's abstract.

[surreal peak]

On the caller side, you don't have to care who implements the interface

You simply call the interface function on the Actor/Object, and if that Actor/Object has the interface AND implements the function, it will execute it

That removes the need of casting to each possible option

[magic gate]

yeah i don't have a lot of experience in blueprints, i learned C++ but overriding and so on is sometimes weird/bad/impossible in blueprints so i don't use it as much as i should in blueprints

[surreal peak]

An example would be:

• BPI_Noise (Blueprint Interface)
  -- Has function "MakeNoise"

• BP_Car
  -- Implements Interface
  -- Overrides "MakeNoise" Function and plays "Honk" sound

• BP_Dog
  -- Implements Interface
  -- Overrides "MakeNoise" Function and plays "Woof" sound

• BP_Player
  -- Traces for Actors
  -- When hitting an Actor, calls "MakeNoise" on the Actor

BP_Car and BP_Dog do not share a custom Parent Class, only Actor, so without the Interface you would need to cast to either of them

Which can quickly grow out of proportion

You basically have two options:

• When you have a lot of Actors that share the same custom Parent Class (e.g. BP_Animal) and you only need to call functions on those, but each Child should do something else, then add the function to the Parent (BP_Animal) and override it in the Child (BP_Dog). When tracing you can cast to BP_Animal and call the function.
• When you have a lot of Actors that DO NOT share the same custom Parent Class, add an Interface to bridge this.

A Combination of this obviously also works. BP_Animal can implement the Interface in addition

For Interaction Systems I usually have an Interaction Interface. Whichs allows me to get the Name, Duration, InteractionType, as well as calling OnInteract etc.
I have a base BP_Interactable Actor which implements the Interface and is used for every Interactable that only needs to be a simple Actor. Convenience.
The Interface can then also be added to Actors that can't be simple Actor children, like a Character, which can't inherit from BP_Interactable.

So your NPC for example (unless your NPC is a stationary Actor and not actually a Character, but overall using Interfaces allows you to not worry about this. Your PlayerCharacter will just call the Interface functions and it's up to the receiving end to implement them).

Hope that clears it somewhat up. Otherwise it might be time to google/youtube this (:

[unreal marten]

it definitely helped a lot, I understand the concept at least but yeah youtube time to see visually how this is all created thank you!

[surreal peak]

👍

[tribal kernel]

how can i change ue5 character for a mixamo character????

[silk cosmos]

Are any anims in the blendspace additive? Normally that deforms meshes like that

[magic gate]

do variables pass by const reference automatically in blueprint functions? i want to pass a struct to a function but i am not sure if i should force it to pass by reference for performance reasons or if it goes by const reference automatically

[silk cosmos]

The same way you'd do it in ue4. There are many tutorials out there

[surreal peak]

I don't think BPs have a concept of const?

I mean, they do kinda, but not sure if per param

Ref would save you a copy of course

[pearl moth]

I have managed to fix the issue.

[raw orbit]

ill need to checkk

[magic gate]

i mean i don't really care if the parameter is const or not, i just don't want it to be copied for obvious performance impact reasons. But i wanted to know if a parameter is automatically passed by const ref (i assume it is but i am not sure)

it might as well be passed by copy automatically but that would surprise me

[glass stump]

how do i make it so if the player interacts with one BP, another BP does something?

[tight schooner]

there's a multitude of ways... https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/Blueprints/UserGuide/BlueprintCommsUsage/

[glass stump]

Thank you. :)

[tight schooner]

a multitude of ways to make blueprints aware of each other (collision, tracing, spawning each other, "get actor of class", etc.), and then a multitude of ways for them to communicate

[glass stump]

get actor of class sounds useful.

[tight schooner]

usually a quick and dirty approach but it does work

[glass stump]

line tracing like when there's line that hits the object, right?

[tight schooner]

yeah. Stuff hitting stuff whether directly through collision or indirectly with various traces are common ways for two BPs to become aware of each other

your player character might collide or overlap with another BP, or it might do a linetrace in some direction and find stuff

[glass stump]

Ahh, I'll have to look into all of them and see what one would work best for me. Thank you! :)

[tight schooner]

yeah, it's all very situational

[proper wyvern]

Is there any way to get the current focused widget?

I see Unreal has "HasUserFocus" but it doesn't tell me which widget is being focused

[hollow gorge]

you could try an array that contains potential widgets that could have the focus and loop through it to find the one that actually has the focus. Maybe there's an easier way for that which I don't know yet

another approach would probably be to make sure that your last performed action determines which widget to focus next

[faint pasture]

There's an OnFocusRecieved so you can just hook into that to update some variable.

[undone surge]

how would i get the distance between my character and an AI character

[faint pasture]

Length(Location - Location)

[remote meteor]

AActor->DistanceTo(OtherActor)

[undone surge]

thanksss

which of these two is more efficient and more reliable

[faint pasture]

Doesn't matter, just use what you want.

[undone surge]

alright

[remote meteor]

Squared versions

because they dont have sqrt

[faint pasture]

DistanceTo is prolly faster because it's c++ native but it's literally a zero.

[undone surge]

ok thank you

[faint pasture]

Won't matter unless you're doing like 100 a frame or whatever but moving your system to C++ will get you a 100x speedup

You can prolly do 100,000 sqrt distance checks in C++ per frame no problem.

[undone surge]

if i wanted to change an AIs speed based on the distance between it and me would i put the distance to node with tick ? or is there a better way to check and update the speed based on distanceto

[faint pasture]

You'd do some sort of test somewhere. Tick or a timer is fine for now, you'd probably want some sort of service later, or some sort of other trigger

[undone surge]

i want to do it in a behaviour tree but im new to BTs how would i set the conditions

[sinful gust]

Hey, how weird is that, after converting my singleplayer functionality to multiplayer, the UI works perfectly in client (mp) but not in listen server or singleplayer? 😅

[faint pasture]

What doesn't work about it?

You probably have some gate on if it's server that's screwing you upt

[sinful gust]

When using drag and drop, for instance, the inventory slots are not updating in real time, but the inventory array itself (both server and client) are

All the UI functionality is set to client only (widgets can't be used in server as far as I know)

Opening and closing the inventory shows the items that are there

[faint pasture]

You're probably checking IsServer to do something and that's breaking it

or Authority

since a listen server and standalone are both authority (not sure if both are considered server or just listen)

[sinful gust]

I don't remember doing that, but I'll give it a look, thanks! 😄

[faint pasture]

Are you trying to do predictive inventory stuff? Like a drag and drop is instant in client's view?

Why are you spamming dots... just ask the question and in the right channel

[sleek kite]

It's a link to my previous post in this channel

[formal parcel]

so what's the equivalent of just a generic class in blueprints? like I just want to build a state manager that is its own entity, what parent would that be in the lil create blueprint thing

[thin panther]

Ah didnt realise it was a different message lol

[thin panther]

An actor

An actor is just a blank template pretty much

[formal parcel]

so an actor doesn't imply any physical body or anything?

[thin panther]

Can do whatever you want

No

[faint pasture]

Actor, Component, or whatever else base class you want

[formal parcel]

alright cool

[faint pasture]

It implies a location but that doesn't matter really.

[formal parcel]

so effectively actor == class ?

[thin panther]

Just beware you cant do singletons in bp

[faint pasture]

Unreal heirarchy goes like UObject -> AActor -> billion other things

[thin panther]

An actor is a class yes

[formal parcel]

no i've been holding references to things in game instance for a pseduo singleton - does that work cuppatea?

[tight schooner]

An actor does physically exist in the world (with a transform), but it's no big to just drop or spawn actors into the level as manager classes

[thin panther]

Ye that works

[faint pasture]

A component on GameInstance is alright, but you might be looking for Subsystems.

er, idk if GameInstance can have components but GameState is where I've done some singleton stuff before switching to Subsystems.

[formal parcel]

like lets say I was making a game director thats going to monitor everything and adjust gameplay stuff - that would be an actor with a ref held in game instance?

[faint pasture]

Actor is fine, it's good enough for Epic

[formal parcel]

gotcha, thanks for the help

will also look into subsystems and components

just to understand these building blocks

[faint pasture]

If you don't know what components are yet, just go over the framework again.

[formal parcel]

i mean i think i do

i meant more the technical implications of them

trying not to prematurely optimize or anything but also trying not to do things the wildly incorrect way

[hollow gorge]

I've got an issue with key input events in two different widgets.
When a submenu is removed from the main menu widget the events from the removed widget (like arrow key navigation) still persist and carry over to the main menu navigation. How can this be avoided?

[slow pewter]

So mhh, i try to update an Old Quest System from, Ue4.23 to Ue5, looks like its not Working on 4.26 anymore too, not only on 5, was there any changes from Structs?

[sinful gust]

You can think of Minecraft, when the player starts dragging the item, it should create a visual slot that is dragged by the mouse (which again, works perfectly on clients but not in sp/listen server), and when they drop it, the slot where it has been dropped updates with the item that was being dragged

Internally everything works, and client's UI is updated, but listen server and sp UI's (just the UI's, the variables work just fine) fail to update in real time

You have to close and open the inventory again to see it updated

[finite gazelle]

not sure if this is the right place to ask, but im currently trying to implement dynamic puddles onto my landscape when it rains. I've created the puddles, and when I set my parameter to the desired number, the puddles appear on my landscape, so all is well in that department. My issue is that I'm trying to add them dynamically when it rains, so the longer it rains the puddles gradually appear and get larger. I've instantiated a dynamic material instance in the constructor script, and set the scalar parameter value which gets updated via a timeline, but for some reason the puddles do not appear, any advice would be greatly appreciated

[tawdry surge]

Did you assign the dynamic material or just create it

[finite gazelle]

I believe I have a assigned the dynamic material yes

[frozen ledge]

would anyone know how I can access a float I define in C++ in BP without having to call "Get FloatDefinedInCPP" or something

[blissful grail]

BP always uses a getter when retrieving a property.

[frozen ledge]

rip, thanks

[faint pasture]

??? Where. I just see you making it and assigning it to a variable.

Raining should be a parameter in your current material though. I wouldn't swap materials for a rain mechanic

[finite gazelle]

I've misunderstood the question then I think

Is there no way to copy placed static meshes into a blueprint and keep location?

[prime ruin]

quick question. is there a way for me to invert orient rotation to movement? i don't want to animate the character strafing left and right but i want the character to walk backwards when it gets a negative forward axis input

[blissful grail]

Just turn off the setting?

Then setup the animations in the blendspace

[prime ruin]

i figured i'd have to do that

i was hoping i wouldn't

[faint pasture]

Drive the rotation yourself

[covert schooner]

Is it possible to hide certain variables from direct access by child blueprints?

[tawdry surge]

Private variables

[covert schooner]

You mean the eye-closed? I tried that, they have access.

[tawdry surge]

No

Private is a different check box

Makes it read only outside the original BP class

[covert schooner]

oh got it, I see it now, thank you so much!

was really getting annoyed with dynamic materials getting exposed directly to children

[undone surge]

with the AI sight config is there any node where i can move the ai to my characters last seen position ?

and then how do i set it to go to the last seen location

[blissful grail]

There should be an event that you can connect to from the component about a sense occurring. In there, I believe there is a field for the location of the sense. Can save that and use it.

[undone surge]

can i do that in a task in behaviour tree ?

[blissful grail]

Do it in the pawn (or controller, wherever you have the sensing stuff) and have it update a value in the blackboard.

[undone surge]

alright thnx

[manic vessel]

Hello 🙂 how could I get the scale of something and change its scale based on a percentage, eg: get scale and increase by 10%

[lone eagle]

I have created a timer(elapsed time) UI by adding 1 integer per 1 second delay. i am currently attempting to pause the timer after i hit a triggerbox or actor with a box collider but i cannot get it to work unfortunately.

this is what i have so far

if anyone could potentially help me find a solution i would highly appreciate it

[manic vessel]

Why not use timer by event and clear handle, as I think event construct acts like begin play and ONLY fires ONCE!

[lone eagle]

i am unfamiliar with how to do it like that

[manic vessel]

event construst fires once here! adds 1 second then ends, You need a actual node that repeates like TICK OR EVEN BETTER

[manic vessel]

FROM CONSTRUCT TYPE TIMER BY EVENT

[tawdry surge]

Setting the scale of an object is always in relation to its original size. If you add .1 to the scale it'll be 10% bigger

[lone eagle]

i appreciate the help AlphaWolf, but i am not so sure. i see that setting it to event tick might help me find the solution though

[manic vessel]

YES but I have set a map variable for certain actors to have custom scale to fit in a location. so each will have different relative scales

[tawdry surge]

Get game time in seconds and make a time span

It will handle the counting for you

[manic vessel]

dont use tick. its expensive. you only use that when no other choice

[tawdry surge]

Set tick enabled to false to make it stop

No it's not

[manic vessel]

I have always heard that it is.

[tawdry surge]

Its overkill in most situations but not inherently bad

[lone eagle]

i cant find those nodes

[tawdry surge]

"Get game time in seconds" and "make timespan"

[manic vessel]

I still think set timer by event and having the looping box ticked. and set the time to 1 second is better.

and when you want to stop the timer use clear and invalidate timer

[lone eagle]

im not sure id be able to show it by the ui the same way as i have it now?

[tawdry surge]

Timer still runs on tick

[manic vessel]

or like this

[lone eagle]

i feel really dumb D:

im so sorry guys

[lone eagle]

id like the timer to pause on WIN so the player can see what time they got

i dont want it to clear

[tawdry surge]

You're fine. If you ever don't know what a node does or how to use it Mathew Wadstein has youtube videos on all of them

[lone eagle]

thanks for the suggestion

im just trying to get this done for an assignment of mine due soon

[manic vessel]

there are tons of tutorials on youtube to do a timer

[tawdry surge]

Id take the 5 mins and look up the suggested nodes. Makes it easier to do the work if you understand what you're doing

Timer by function or event or the game time and timespan

Either will work

How can i make my flashlight be off when the game starts^???

i will watch it, thanks

[manic vessel]

This is why I asked about scale in %. as hard coded scale is causing issues because some actor's have different scales.

[marsh oak]

Why does this blueprint crash my engine when I try to place it in the scene?

Its on an editor actor. I'm trying to spawn a random actor when I place it in the level. The variants are all regular actors.

[coarse marten]

Is there anything like event hit that returns when the actor is not hitting something? I notice event hit only seems to fire when it is colliding with something.

[manic vessel]

did you try in event graph and not construction script too?

[marsh oak]

I did not. What event would I use? Begin play? I want the BP to run when i put in in the level in the editor, not in play mode.

[manic vessel]

I had issues with spawn actor in construction script once

[marsh oak]

I'm trying to simplify my level building by having the engine randomly pick an actor instead of me having to.

IE one of the 6 walls I have

[tawdry surge]

iirc all you gotta do is put your offset in the vector + vector node on the bottom of the screen and plug that in b

[thin panther]

Use an editor bp instead

If you want actor spawning at a location

Thats editor utility

[manic vessel]

You can tell I was thinking this before I asked. I was so close 🙂 will give this a try

[marsh oak]

ah you are right, I picked utility. I'll give it a whirl.

[lone eagle]

sorry to bother you but

do you know how to get these variables

i am very unfamiliar with them

[dapper iron]

Is there a way to set the terminal velocity of a Character?
Or more specifically, the maximum fall speed for it?

[dapper iron]

Just drag it from the list into the graph.

[lone eagle]

thats not my screenshot. its from a tutorial video

i do not have that option sadly

[marsh oak]

do you know the exact class name, by chance? I can only find the EditorUtilityActor one.

[thin panther]

Might want an editor utility widget i think

[dapper iron]

Ah. Them being there means that it's not something that you GET, it's a variable that you need to add yourself by pressing the + button next to the variables list header.

[thin panther]

But an editor utility actor should work

[marsh oak]

editor utility actor is what is currently crashing

[marsh oak]

uhm.. editor utility widget seems to be meant for some sort of UI? I dont see a blueprint section

[thin panther]

Is there any other thing that spawn actor

In the editor utility actor there is a section for assets try looking there

Theres a section for editor utility soecific actions

Id hazard a guess that it will be in there

I Have this problem in flashlight
if i dont have the y pitch the flashlight is good and follows camera, but dont replicate y axis movement
if i have it replicates the y axis movment , but it doesnt stick to camera it just goes
can someone help me pls

[marsh oak]

I mean there are nodes for manipulating assets in the content drawer. Like checkout asset, delete asset, etc. But they take asset paths, not classes to spawn? 🤔

spawn actor from object seems to work!

I guess it doesnt like spawning from class for some reason

[undone surge]

if i am stuck in this node does that mean the current one is nver done executing or that it cant go to the next one

[lone eagle]

does anyone know what these variables are within a widget

this is what im trying to do

but i have no idea how to make the variable

[marsh oak]

text boxes?

because the BP is setting text values, and the TB prefix makes sense for it to be a text box

[lone eagle]

im unable to make them into variables

[raw orbit]

how do i convey to other clients in an online game that player X's head is turned based on their third or first person camera? the camera components exist only on the locally controlled client so im wondering how to go about it

[fickle dune]

Bump

[thin panther]

Tick is variable on the text in the designer

[lone eagle]

thank you so much

[thin panther]

no problem

[lone eagle]

now i wonder if i would be able to do a >= 60 to make a minute counter

but its not an integer so im not sure if its possible

[thin panther]

just truncate it

for minutes you only wanna show 1 minute even if the real time is 1.793 minutes

[lone eagle]

could you explain that further? or direct me a little. i am very unsure what a truncate is

[thin panther]

truncate chops off the decimal point, both 1.32435 and 1.4589 would become 1 when truncated

also conveniently there is a node called truncate

[lone eagle]

i would not know how to incorporate this into my elapsed time widget

[thin panther]

so if you divide that by 60 it should give you the minutes, e.g. 390 seconds, would be 6.5 minutes, and then truncate it so you only have 6 minutes

if im understanding game time in seconds

which i think i am

[limpid bronze]

How would I shrink a capsule collider from the top first?

Like say if I had a character I wanted to crouch and shrink their hitbox.

[lone eagle]

would that only work if i made my timer with + 1 integer every 1 second

[faint pasture]

Shrink and move mesh at the same time

[thin panther]

no

you have game time

that gives you the seconds accumulating

so if you also divide that by 60 and truncate it, it converts it to minutes

[lone eagle]

i appreciate your attempt to explain it further. i just cant bring myself to understand what you are saying and i cant picture how to incorporate this solution

[thin panther]

i have given you the nodes

you want to display minutes and seconds, r just count minutes?

[lone eagle]

the code i have currently counts up the ingame seconds with milliseconds, but it climbs past 60 and continues to increase

was wondering if i could reset seconds to 0 as it hits 60, then add 1 to my minute

[thin panther]

not sure if you can manually set game time

but you could always manually subtract 60 - whatever amount of minutes

so until you hit the first 60 it would be game time - 60 * 0 which is just the game time

then after that it would be 60* 1 etc

[lone eagle]

i think i might just keep it the way it is

[faint pasture]

Are you adding numbers together to get game time?

[lone eagle]

i have created 2 different widgets now with different ways to get time and im so lost

[wraith wedge]

I retargeted a mesh to another and made a new animation BP and all works in the game, but only the line trace won't hit the new mesh.
What could be the problem?

[lone eagle]

i just want the timer to stop when i hit a triggerbox that shows my WIN widget

[faint pasture]

If you're trying to time something, just store game time in a variable StartTime, then GameTime - StartTime will be your elapsed time. Do math on it for formatting if you want.

[thin panther]

thats what i was tryina explain

[faint pasture]

And probably store ElapsedTime as a variable somewhere so you're not calculating it twice

Game instance or game state or player state or wherever.

[lone eagle]

i genuinely cant wrap my head around what you guys are saying

[faint pasture]

Can you wrap your head around the concept of storing time as a float? It's just the number of seconds

[lone eagle]

this is one of the ways i have done it

it works perfectly fine

and the way i want it

but i cant get the timer to pause completely when i hit a trigger box

which is why i am in this mess

[faint pasture]

What is this for some sort of a lap timer?

[lone eagle]

the only tutorials i can find is from someone named Mathew Wadstein but they are extremely unhelpful

[thin panther]

poor mathew

[faint pasture]

Those are the best tutorials, succinct and to the point, and don't hold your hand.

[thin panther]

we have given ya the nodes ya need you just need to plug em in

[lone eagle]

im making a game where i need to platform from start to finish. timer starts on spawn and id like the timer to pause/stop once i finish/win the level

[faint pasture]

The UI should have nothing to do with controlling the time, all it does is report the news, it doesn't make it.

Put all the time handling stuff in game state or your Pawn or some actor or whatever.

I would probably make an actor for the finish line and have that handle the time.

[lone eagle]

but then how do i show the time handling through the UI

[faint pasture]

After all, that's the actor that's going to handle detecting a finish

[faint pasture]

Your UI gets the time from that actor

[lone eagle]

i created an actor blueprint that acts as a trigger box

[thin panther]

the time tracking isnt done in the ui, they are just getting game time

[lone eagle]

oh

[faint pasture]

Okay, put all the time stuff there.

[thin panther]

they have got time tracking they just need to format it

[faint pasture]

Event begin play, set start time. On the trigger, set end time. Event tick, set current time

[faint pasture]

If they are doing gameplay stuff in UI then shits already fucked, just do it right the first time

[faint pasture]

Do this on your trigger actor

[thin panther]

thats their current way

[faint pasture]

I mean that can sort of work but it's pretty bad. Number one it relies on game time being the elapsed time, so no such thing as a start countdown or anything else. Also, it breaks when you want to register the finish time.

[lone eagle]

set start time end time current time

new variables?

[thin panther]

yes

[lone eagle]

all integers too?

[thin panther]

nah youll want floats

[faint pasture]

Yes make those three floats

You understand what I'm getting at here or you just going through the motions?

[lone eagle]

im so sorry to both of you for the inconvenience. my first time doing something like this

thank you for all the help nonetheless i really appreciate your time

[lone eagle]

a bit of both i think

i understand youd want to set the end time as current time once the end of the level is triggered

but start time would need to be triggered via another actor?

[faint pasture]

And CurrentTime = GameTime-StartTime

[faint pasture]

Begin play

Later you can do it different if you want (starting countdown or whatever)

[lone eagle]

i think i understand it but im not sure how to integrate it right now

give me a second and ill show my attempt

[faint pasture]

First check that it's working. Print CurrentTime when you set it and make sure it's going up

[lone eagle]

i have a hunch that im putting it in the wrong place though

nothing prints

[faint pasture]

@lone eagle
Begin Play -> Set StartTime = GameTime

You want to set the value of StartTime to be whatever GameTimeSeconds is at BeginPlay. It will be 0 or close to it but later you might want to start timing a different way

Then on Tick
Tick -> Set CurrentTime = GameTimeSeconds - StartTime

So every tick, CurrentTime will be equal to GameTimeSeconds - StartTime. This will usually be the same as GameTimeSeconds but might be different if you started later than Begin Play.

[lone eagle]

i think im too stupid for this honestly

[faint pasture]

Whenever the end level trigger is hit

Event Begin Overlap -> Check to make sure it was the player -> Set EndTime = GameTimeSeconds.

[lone eagle]

i know this is wrong but

when you say = game time

i leave start time alone

then on tick

okay

wait

[faint pasture]

Begin Play, set Start Time = GameTimeSeconds or whatever the time node is called

[lone eagle]

there is a node for game time

damn
