blueprint

[warped juniper]

If the player overlaps with a different camera BB while also being inside a 2nd camera BB, the system breaks if the player was to walk away instead of keep walking forward

[lunar sleet]

I don’t see the mesh. Use simulate

[warped juniper]

I would absolutely love to get suggestions for a more efficient or clean method to get what I want... This is just what I managed to make through my own research

I haven't been able to truly remove the error, just add workarounds

[gusty crater]

Sorry what do you mean by that? (i may be a noob xD)

[spark steppe]

i can't tell you a fix as i don't know the whole system, but you could totally check all the boxes for overlaps (might even work fine in the construction script if you don't have thousands of them) then change their color or something to visualize the faulty ones

[lunar sleet]

The navmesh. And 3 dots next to play button let you change it to Simulate. F8 also toggles that at runtime

[warped juniper]

I can't say I know how to do that sadly

I'm an artist first, so navigating programming is very, very tricky

[lunar sleet]

You’ll also prly need to use either RVO or DetourCrowdAIController so they can nav around obstacles

[gusty crater]

Navmesh shows fine

[chilly dirge]

my blueprint broke in some way, I already tried multiple things but I can't fix it, essentially one component is broken (the details window is blank), the only way to "fix" it is to reconstruct the blueprint right?

[gusty crater]

but that blocked print string keeps firing and its not moving

[lunar sleet]

You’ll need to debug using the visual logger. There’s also some vis log nodes that allow you to see shaped traces at the projected goal

[gusty crater]

Thanks ill google away and try get it sussed

[lunar sleet]

Def try RVO (on char settings) or using the experimental detour crowd controller as well, as they’re the main tools for handling navigating around obstacles

[gusty crater]

Rogey, i think im gonna turn off collision on the people so they walk through each other, its sort of a city builder / rts game so there will be heaps walking along paths, but i havent started any of the paths just yet

[gusty crater]

Found it in the logger, i was accidently setting the walk speed to 0 during a certain function xD Atleast ive gained the knowledge of loggers now

[wanton prism]

so remove it?

[lilac storm]

hello devs ASAP ASAP ! how to get actors that is already overlapping box collision on begin play (i want to get this cow) when game started , and doing this code doesn't help

[dark drum]

That's how you do it but if it's not returning anything, it might be that the cow hasn't loaded yet. You can try adding a delay until next tick which should give time for everything to load before it's run.

[lilac storm]

i did a delay for 3 secs , it is not returning anything , i thought may be problem with collsion , but interestingly when u try to just drag another cow to box collsion OnBeginOverlap function works just fine , WTH?

[dark drum]

It could be that the animal doesn't have the animal tag? Seems like a redundant check though as you getting actors that are BP animal base which I would assume would always be an animal.

Adding to that you then use a cast and check if it's in the array even though you're using add unique. The get overlapping actors would only return an actor once soon begin play I would imagine it would already be empty so you should just be able to add them to the array without checking anything.

As a guess, I would imagine that it would only recreate the class widget if the old one as been garbage collected.

[lilac storm]

GetOvelappingActtors Returning me an empty array , even tho cow inside of box collider

[dark drum]

Odd, are the animals set to generate overlap events in the collision settingsm

[hollow jasper]

Hallo Could i know how to make variable for animation ?

want to change in viewport, but i don't know how...

can not find 'promote variable'... mhh

[dark drum]

Does anyone know why the instance component that's created using the foliage painter might not be correctly returned from a trace? The trace is picking it up but when I store the hit, it doesn't have any of the date like the specific component and the hit item.

Edit: Nm, it's a me issue lol.

[frosty heron]

I'm pretty sure the bug is caused on Ur end, I used grid panel just fine for forever for countless times.

Check if they actually get destroyed and check what ever it is you are adding

Its possible that you probably just add to the rows and collumn instead setting the row and column back to 0

[sour moat]

✋ Hello, how to fix the issue that player will lose mouse control after close a widget? I have to click mouse button once to get it again.

[frosty heron]

Not smart just past mistake. But anyway need to know what a actually went on your end. When you create widget it should add a brand new instance of the widget

[frosty heron]

Set input mode to game and UI and chose lock always

Don't think so. I just tick that when I need to expose on spawn

Static variable is probably a cpp thing, I am not aware of being able to do that in bp

Closing and opening doesn't equate to destroy

For widget , instance get destroyed when it's deemed unreachable

So you have to remove from parent then set the variable to null

Remove from parent doesn't destroy the widget, it just remove the widget from the viewport. It can still be added anytime

[native canopy]

i have this on UI, hwo to cast to blueprint? create widget can't read the value

[frosty heron]

Normally you should never have the need to clear or delete your inventory widget

Simply refresh it by clearing the inventories and reinitializing data (eg row and collumn)

[dark drum]

I'm currently working on an interaction system that works with static mesh instances where when you interact, it switches the specific instance out for an actor mesh. Does anyone have any suggestions on how I might get what actor needs to be spawned based on the hit instance? Other than checking the actual static mesh and use it as the key in a map, I'm not sure what other options I might have.

[frosty heron]

@dark drum what's the map pairing?

[dark drum]

That was my initial thought but other than using the static mesh, I'm not sure what other options I might have for the key.

Edit: I guess tags could be an options but I would imagine that would get messy to keep updated.

[frosty heron]

Not sure what you are trying to do, need more info
But you should check Matthew blueprint communication video to help you understand with your current problem

[sour moat]

I did, but it didn't work. I wrote this in the controller blueprint.

[frosty heron]

Do it after you create the widget and feed the widget to the in widget to focus. Also don't forget to show mouse cursor

[frosty heron]

R u trying to spawn multiple static meshed based on what you hit?

[native canopy]

try to read Widget variable

[frosty heron]

Still unsure what's what. I suggest watch the video. Bp comps is essential.

If you need to read or set q variable inside a widget, promote the widget to variable on create widget node. You can then access your variable via the variable.

And can't stress this enough, watch the blueprint coms video by Matthew

[dark drum]

It's so I can interact/do something with static mesh instances. So it could be grass, trees, rocks etc... So when the player goes to interact with it, it'll spawn the relevant actor in the same place as the hit instance and remove the instance. Also, once the player moves far enough away from said actor, it'll destroy itself and add an instance back to the ISMC. That's the idea anyway.

[dreamy elm]

How do i use current pawn rotation for movement instead of input?

[gusty crater]

I need some math help xD So i have a "Clockwork" variable on my gamestate that is always counting up. On my building being constructed i need to work out how long it has been worked on for. How can i pass that through and keep track of only how long it has been worked on for and not the overall clockwork time

That is what i currently have, but obviously once the time has already elapsed a certain amount, the buildings just insta finish.

[dark drum]

When work starts, store the current clock work value. Then you would just take the current clock work value and minus the initial value when work started.

[gusty crater]

Would it be something like that? Except put the set clockwork paused time before this function runs to store it beforehand

[dark drum]

Another option is to have an event dispatcher on the game state that is called when the clockwork var is updated. Something like 'OnClockworkUpdated'. Then when you start work, you bind to the event dispatcher. When it's triggered, you increment a value each time. When it reaches a specific number, work is complete. If you stop work, you unbind the event.

[gusty crater]

Only hard thing is working out how to store it only once as it all runs on the on tick function

Ahh yep so a bind should work much better in my case then

[dark drum]

Yea, with you wanting to be able to stop the work a binding makes the most sense. That way, it only updates when it needs to.

[gusty crater]

havent really used event dispatchers, ill post here once done to make sure i get it right xD

Does that look right?

nope i messed something up xD

[dark drum]

Something like this.

The top bit would go in your gamestate for updating clockwork. The bottom bit would be in what ever you want to build. The target on the bind nodes would be your game state the 'OnClockWorkUpdated' would be on.

[gusty crater]

With the "Call On Clockwork Updated" in my gamestate, it wants me to input my building as target, is that normal? i thought it just broadcasts a message to anything listening to it

So event dispatcher is on my building, then if i use the call from gamestate that should trigger it right? why do i need to put the building reference into the gamestate to call it

[mental trellis]

Well, it's calling a specific event dispatcher.

The one on one specific building.

How does it know which building's event dispatcher to call unless you tell it?

[gusty crater]

i didnt even think of that, yeah that aint gonna work then

theres no way i can store a reference of every building in the gamestate on a city building sorta game xD

[mental trellis]

Indeed

What even is this event? Why is the game state calling it and not teh building?

[gusty crater]

Have you got any suggestions of a nice way to do this? pretty much my gamestate keeps track of game time. When my building has more than 1 worker, it starts building. After a set building time has elapsed i then full spawn it.

So im struggling to find a nice way to pass through the game time, then work out the elapsed time of actual building

[mental trellis]

Why not set a timer on the building itself?

[gusty crater]

i had a branch on tick for if theres more then 1 worker if true, then "do work" just wasnt sure how to calculate the difference as it was on tick, so setting a starting time was hard'

[mental trellis]

On a random note, I really need some sort of text preprocessor on discord that changes "hte" to "the".

Don't use tick for that. Use a timer.

Or a delay node.

[versed sun]

what would be the point of that?

[mental trellis]

Of what?

[versed sun]

i asked "what would be hte point.." then fixed it

[gusty crater]

Im mainly just not sure how to set the starting time only once, and not repeatedly. Although i check if theres a workforce repeatedly and only want to set it the second that turns true

Is it okay to do that?

i made a timer function run this "Check Workforce" so then itll set it once when it starts, then start counting time and actually progressing the construction inside the "Do Work" event. Then if the workforce drops off, it will reset the time to 0 and reset the do once node

is that acceptable? (im very fresh so dont know bad practices)

[drowsy ether]

Hello. I need to use the "Deproject Scene Capture to World" node but it requires a "Scene Capture 2D Object Reference". Instead, I have a "Scene Capture Component 2D Object Reference". How can I implement this function with reference to my component? I thank you for your assistance.

[gusty crater]

damn i cant work this out xD

So i managed to store the starting clockwork time (from the gamestate) for when it starts work then im just trying to work the math for it all. The *60 is to convert minutes to hours but it still seems to be slightly off time

This "Do Work" is running in tick too with a gate to start / stop it

[silent drift]

Is there something like on-quit in Unreal? My projectiles keeps complaning when I haven't "destroyed" them yet, and exit the game.

[dark drum]

You only call that function in your gamestate where you update the clockwork var. Every where else would bind to it. I think thats where you're getting it confused.

Think of it like having a bell that makes a specific sound. When you create an event dispatcher it's like specifing a sound. When you call the event dispatcher, you play the sound. When you bind to an event dispatcher it like listening out for the sound and doing something if you hear it. (this isn't actually what happens but i think it helps understand how you would use it)

[gusty crater]

Yeah but to use that i would still need a reference to my building from inside the gamestate correct?

Which isnt really feasable in my application

[dark drum]

No, your gamestate doesn't need to know anything about who binds to it.

[gusty crater]

The attachment you replied to that was in my gamestate, it wouldnt let me use that without a reference to my building for some reason

Unless i set it up wrong, probably did xD

[dark drum]

Make sure you create the event dispatcher in the game state (as there where it would be called from) and not your building.

[gusty crater]

ahhh yeah i had it the other way round xD

[versed sun]

Game Instance has a Event Shutdown
Blueprints have Event Destroyed and Event End Play

[silent drift]

Ah, Event end play I think might be what I'm looking for! Because I already used Destroyed for other stuff.

I will have a look! Thank you

[gusty crater]

Okay sweet got the event dispatcher working, now just the actual math for the do work

[dark drum]

Does anyone know of a good way to blend different PP settings together? I'm not using PP volumes as the player might need effects applying regardless of where they are so are done directly on the camera.

[proper wyvern]

Trying to figure out what actors are taking up physics time - is there a way to print all actors contributing to physics calculations?

[versed sun]

i never messed with it , but would it be in here on your Camera?

[dark drum]

I'm not using PP materials (at the moment), it's just the main PP settings.

[late basalt]

Do anyone know how to code a System that convert 1000 into 1k to 1m to 1b and so on?

Money wise?

[last bloom]

hey guys is there a way I can change the shape of a scene capture component 2D's view frustum?

im making portals for my game and i want to set the bounds of the view frustum to the bounds of the portal plane so as to avoid rendering objects outside those bounds

like in this video

https://www.youtube.com/watch?v=w-Z1Fx0LvDc&t=1283s

[flint junco]

Hello, I have done a build my game, and some of the Niagara effects have dissappear in the build. Does someone knows about this problem?

[green barn]

Maybe the build settings? could be that the effects get turned off because they are using features not enabled in the build settings.
could be missing materials on emitters making them not render, though then usually you get a checkerboard texture. could be something related though

[cursive cosmos]

hey. how would i make this work. so only when a staticmeshactor (with the tag "PickUp") from the level touches the trigger in the Bp actor. The staticMeshactor already has the tag applied

[jaunty solstice]

I've created a light actor Blueprint. ie an Actor Blueprint with an embedded Point Light.
When I drag the BP to my scene I see that all the light properties are still exposed (circled in pink)

How can I hide or at least lock these properties in the editor? The only thing that should be exposed is the position (Transform).
.

[dawn gazelle]

If it's the actor that has the tag, then you want to use "Other Actor" and check if "Actor has tag"

[cursive cosmos]

cheers!

[crimson saddle]

Does anyone know if interfaces can be called in async functions? Or is that illegal unless done on the main thread?

[hoary junco]

is there a way to detect whether or not the location of a line trace's hit is inside the trigger box of a different actor?

basically I want the trace to follow the character and return one result if the part of the character the trace is hitting is inside a box, and a different result if that part is outside the box

but just making the box block the trace causes issues

[pale imp]

@hoary junco Finished the movement yesterday, everything works as it should

Now I'm figuring out the interaction system to support more than just the lever

[hoary junco]

using what you already have you should be able to figure the rest out

[pale imp]

Yeah, it seems to be going fine

[hoary junco]

but ask if you need help of course

[pale imp]

of course

[north lynx]

Hey everyone!
I'm working on 2D minigame and I'm wondering, how to make the lights to work? All the Tilemap is bright, and adding any source of light seems to not work
Anyone know how to fix/change that?

[hoary junco]

are you just trying to get an even ambient light?

[quasi dirge]

Hey, does anyone know how can I pass parameters to an event that I called with a timer?

[north lynx]

I want to make my own source lights in the map
All the Tilemap is bright and any light source doesn't work

[spice smelt]

is there some way to get the exact name of a component as displayed in the editor? the "get display name" node adds a bunch of stuff to the text

[spark steppe]

you are probably looking for GetClass() -> GetClassDisplayName()

[spice smelt]

for instance from this I want "qwe". Its type is a static mesh component

[spice smelt]

in fact i'm looking for the exact opposite of that xD

[spark steppe]

ok nvm

[true valve]

Is there way to know when the movement has changed without using EventTick or SetTImer?

[spark steppe]

make yourself a setter and use only that?

[true valve]

?

So a character goes into the water volume. Automatically the mode changes to swimming.

[spark steppe]

does the water system do this?

[timber crystal]

I'm currently making a side scroller runner game and I'm wondering why my character gets animated in the fall animation when I jump twice in a row

Is it a matter of speed?

the friend said "you haven't shared your code, can't say much. it is possible related with the transition from jump -> fall. you might want to add an "and" boolean and add another condition, such as timeRemaining (ratio) <= 0.1"

But how i try to implement that is noob like i now ...

[trim matrix]

I have a main Skeletal Mesh that is the nude body of the character. I also have child Skeletal Meshes that are the various clothing (pants, shirt).
The main skeletal mesh uses an animation blueprint. I made the clothing follow the animation of the main body by using "Set Leader Pose Component".

It follows the animation perfectly, however, when I set a morph target on the main body, the children (clothing) do not deform, only the main body deforms. How do I make all clothing deform with the main body morph targets?
I used "Set Morph Target" node inside the Animation blueprint for setting the morph target.

[pale imp]

@hoary junco real quick, I'm trying to get some gui to show in the viewport but this isn't working. Is there something obvious which I'm missing ?

[dawn gazelle]

You can't. Timers are bound to a specific delegate that returns no values.

[hoary junco]

which blueprint is this sat on?

[pale imp]

its own, just the graph window in the widget

again, it could just be a checkbox I have to tick in the details or something dumb

[hoary junco]

then you need to have something like this in the gamemode blueprint

[pale imp]

Alright I'll do that then

[hoary junco]

replace "general UI" with whatever the UI is you're doing either way the widget won't do anything unless you create it on a blueprint that exists in the scene

[pale imp]

Yep everything works fine, just been a while since I last added ui so I forgot how everything works

I'll add a hitbox to the lever to make it easier to hit

[hoary junco]

it's ok I'm just melting my brain right now with a massive tree of conditionals on whether or not something is detected because I wanted to be fancy 🥲

[pale imp]

That's what I did with my interaction system, albeit on a much smaller scale I'm guessing

I'm done for today, everything works fine and I'm happy with how it is so far. Next I need to learn how to properly animate stuff

Cya : )

[hoary junco]

good luck!

[pale imp]

and thanks for the help again

[pale imp]

you too

[flint junco]

Hello, I'm having a problem with some problems with niagara effects, some of them (not all) dissapear in the build, but I can see them playing in the editor mode, can someone help me?

[flint junco]

thx!

[winter pebble]

Could you add a trigger volume around the water and use that to fire off an event on the player character which switches their movement mode to swimming?

Alternatively you could add a check to the movement input that checks if the player is currently in water or not before deciding what to do, but that's probably less optimal and could lead to funky behaviour if the player is technically in/out of water but hasn't given a movement input recently

[steady night]

Question, when doing a options widget, do u normaly put it in the menu controller, och player controller or do a seperate for each one
?

[indigo lake]

Anyone got any knowledge as to why Box Collisions wouldn't block a Character Capsule that is marked WorldStatic or a Custom Object Type? Having trouble figuring this one out. I have both objects set to Block on all Objects/Channels (a character capsule, and a lone box collision), but when switching the character capsule collision object type to either WorldStatic, or making a Custom Object Type, the capsule falls through. Works fine on all the other Object types (pawn, vehicle, destructible, etc)

The reason this is particularly noticable is that 2D tilesets seem to just use a bunch of box collisions. So my character falls through it if I make a custom object type! Wanted to make one called "Hero" to make some other parts of the code cleaner.

Oddly enough, if I toss a regular shape cube under the capsule, the capsule will be blocked by that regardless of the collison object type. From what I'm able to gather, it seems like it's an issue particular to the Capsule component on characters. It just doesn't seem to like being a WorldStatic or CustomObject Type (maybe it has something to do with it being the root? no idea really).

Looking more into it, i made a new character, and this one doesn't seem to be having any problems, makes me wonder if my character is corrupted.

[oak fable]

hey there
i have this simple movement setup
i have an issue when i click one of the movement keys like W for forward i get the correct value which is 1 or -1 for the opposite but if i hold W and D i get a value of 7.07 why is that ?
i should have 1 on each of them

[high path]

Any idea why the NavMeshBoundVolume is under the floor?

[dire frost]

Yeah I have that issue too. Sometimes the nav mesh likes to shift away for whatever reason. A temporary fix is to set the nav mesh generation to dynamic under the project settings

[dire frost]

This smells super unity-like. Why not use CMC?

[subtle mist]

Hey guys! I have a variable called Distance which is increasing according to delta seconds using event tick.. I want after 10 seconds to take the value of the distance at that specific time and put it in another variable. How can i do it ?

[oak fable]

what is CMC

[dire frost]

Character movement component. It's the built-in movement component that comes in the character class

All that code above you have would be just 4 nodes

[oak fable]

oh i see
i like root motion movement more

[dire frost]

CMC supports that too

[oak fable]

how

i dont want the character to be pushed with the add movement input

[dire frost]

On tick check if the var modulo 10 == 0. If true then move it to another variable.

[dire frost]

I have not played around much with the rootmotion stuff in CMC but I know it supports it

[oak fable]

idk if you know that already but using root motion animations all i need to do it give it some value and it will move based on it

i dont like to push the character around and play animation using the normal method as a lot of sliding happens and it wont look good

[oak fable]

also still my issue is that number why it comes out when i click on both movement keys

[marble tusk]

So that you don't move faster when going diagonal

[oak fable]

but i didn't set it up that way XD it should give 1

[marble tusk]

might be an option to disable it in enhanced input. I don't know much about enhanced input though to know if it does ¯_(ツ)_/¯

[oak fable]

its not related to the enhanced input
i get a value of 1 for forward and -1 for back ward that works just fine if i click one key and used to work fine when i click w and d or s too but somehow now it doesn't

[dire frost]

Add a breakpoint on one of the print strings. See if any values are out of the ordinary (just hover over the pin you wanna check)

[oak fable]

if its related to the enhanced input it used to work before and i didn't make any change to it

[oak fable]

will try

and if so how can i check for that

and nope the value is getting as 1 and -1 from the the keys so thats not the issue

nvm its the normalize somehow it's not working any more and that was the issue

[lusty hedge]

That's awesome thanks

[cunning flume]

I'm trying to read mouse movement (delta movement over time, I don't care about position), I setup an IA_Rotate with Vector2D value and in my context map added the "Mouse XY 2D-Axis". It mostly works but when moving the mouse to the left for example I'll get alternating positive and negative values such as 10 and -10 one after another which makes no sense to me, am I setting this up wrong?

(I'm showing mouse cursor so this is only triggering on click if that makes a difference)

[random pulsar]

im setting up a character what does it need to have ,a controller,gamemode,instance,default pawn and?

game instance also

and game state or player state?

[frosty heron]

What ever you need for your game. It's a design question you have to decide

[hollow cove]

how do savegames work in multiplayer, like if the person who started the server on their computer saves their game, would the server be able to load that or would it specifically have to be saved by the server

[frosty heron]

That depends on your design

You can make everyone save locally too, nothing stopping you to do that

I just let client save their own file. When they join, they send their save file info to the server. Easy to be abused but nothing that concern a small studio

[cunning flume]

For anyone who cares I changes input mode to game only (instead of game+ui) and this resolved itself.

[warped juniper]

Hey there.
Is there a variant of OnActorBeginOverlap, for JUST a component of the actor? I wanna use a specific collider for the player rather than a the overall volume of the player

[dawn gazelle]

OnComponentBeginOverlap

[split girder]

Can anyone tell me why when i wrap a uniform grid in a scroll box it adds huge spaces inbetween rows, or if i set to horizontal it adds huge spaces between buttons

[warped juniper]

@dawn gazelle Thank you very much!

[random pulsar]

How do i move the character up and down?this does not work

its 2d

[dawn gazelle]

If you're using the CMC and trying to use the "Up" vector, you'd need to set the movement mode to flying.

[random pulsar]

woooooooooooow

nice

ahah,didnt think about this

thanks❤️

[unkempt warren]

When I destroy my actor (Respawn Player) is there a way to keep the same widget and not create a new one?

[fluid compass]

I have a variable that is being generated, but I need to call that variable before generation happens (a few ticks later)

I can hack it but shoving in a "Delay" node before the get variable, but is there a better way to manage this?

[dawn gazelle]

When you generate the variable have that call the generation.

[pallid nest]

hey guys, on event beging play I am casting my character blueprint. Then when I overlap a trigger I am taking a boolean from my character bp and setting up that bool to the true/ off when I end overlapping. Then in my character, I have an event (warning zone) that displays a widget when the bool is on and when off it removes the widget from the parent. The widget is displayed but it is never removed, what did I do wrong please?

[hollow cove]

im setting up my main game save system. i've decided to load it in my game state for the person whos starting the server and replicating it. is there a way to expose a variable and set it before gamestate has begun for the slot name?

[hollow cove]

cant see here how you're removing it

[dawn gazelle]

If you want to persist the selection of a slot name after a level transition you could store it in the game instance.

Just a heads up though, you can't replicate a save game to others.

[hollow cove]

how would you go about replicating the save game data? do i really need to replicate each variable separately

[dawn gazelle]

What save game data is it that you would need to replicate?
Generally speaking, if you're relying on the server to save the game, you'd be restoring the game to the state at which you saved it at - that means you'd be storing values from all replicated actors etc. You shouldn't necessarily need to replicate all those values to clients as you'd be spawning and restoring those values into replicated actors anyway.

[hollow cove]

for example, i have 15 pieces of floating crystal that players can collect spawning at the start of the game. They spawn at random locations with random rotations and scales, random meshes etc. they move up and down and spin. using replicated movement and actors seems very wasteful in that case so i was going to use a random seed and stream and then i havent thought this through yet - somehow save which are collected.

the saves will be client side and its using a dedicated server on the client that starts the game

[dawn gazelle]

The crystals should likely be replicated actors if you're expecting clients to interact with them, or they could be components of a single actor, possibly even part of an HISM. The movement can be done entirely locally if they're not moving around the map.

[hollow cove]

does replicating actors have any overhead vs just spawning them when a client joins based on the seed? they should be identical regardless

[dawn gazelle]

Sure they do, but if you're only dealing with 15 actors it's kind of moot. Regardless, even if you did spawn them locally on the client, while also spawning them on the server, you could make them net addressable, thus, you can have it so that the server spawns the actors locally, makes them net addressable & stably named, and sets the replicated value of whether or not its been collected.

When the client receives the seed and proceeds to spawn the crystals, it too can spawn them, make them net addressable & stably named, thus making them replicated, and will receive the replicated value which you can then drive to show/hide the crystal in question. No matter how you look at it, each value still needs to be replicated in some way to the client.

[pallid nest]

do you have any idea what am I doing wrong here please?

[hollow cove]

is your variable valid? try a print after is valid

[dawn gazelle]

Your problem could stem from multiple overlaps occuring that you didn't want to occur at once as each time "Warning Zone" is called by any actor that is overlapping with your zones and it's creating a new widget and adding it to your screen, but your code will only remove the most recently created one.

[pallid nest]

yes it is, it prints

[hollow cove]

oh true, you might be making a ton of widgets? check if its valid before you create it

make sure you only make one

[pallid nest]

oh really, that could be possible thanks. should i use player character as overlaping actor?

[pallid nest]

thank you, how can I do that please? creating a variable and checking if that is true then creating the widget?

[dawn gazelle]

Do this same thing but only create if "Is Not Valid"

[hollow cove]

yeah i guess you could use a boolean, but if the widget variable is in the same blueprint

^^

[dawn gazelle]

Yeah, I'd maybe check to make sure the overlaps and end overlaps are checking if it's the player. Just an "Other Actor" == "Get Player Character 0" should work.

[pallid nest]

like this right?

[dawn gazelle]

No. Check if valid before the create and set.

You only want to create a single instance of the widget ever. If it gets removed, then a new one can be created.

[hollow cove]

thanks datura btw

[pallid nest]

oh ok I see thanks

it gives me error with the boolean 😦

[pallid nest]

is not , maybe that is the problem? what i Showed is the level blueprint and the bool is in the character bp

[lunar musk]

I wanna make ads system. I wanna move arms to camera. How can I calculate the Ik hands location?

[livid axle]

How could I go about debuging what is constantly interrupting my attack animations?

[turbid ether]

Does calling RemoveFromParent on a widget also properly "destroy" it and remove it from memory?

[surreal peak]

Yes and no.

It does not Destroy and Remove it from memory.

But it's a step towards it. A Widget, like any other UObject, gets cleaned up automatically by the GarbageCollection system when there are no more references to it.

If you remove the Widget from the Parent, but you keep it referenced in some variable, then it will remain alive

If you however clear all references to it, then it will be cleaned up automatically during the next GC cycle.

hey now the enemy flyes just straight ,how can i make him fly randomly up and down at the same time?

[stuck dragon]

Hey guys any help with putting a int variable into a text variable? So I put the text on a widget it displays the int then the text for example

[boreal crypt]

Hello!

So I'm converting my 3rd person controller to operator more like a twin stick shooter (one joystick for movement, the other for aiming and turning, or with a mouse using the mouse position as the aim direction, and wasd as movement).

The camera is fixed, and I'm trying to rotate the player to a given direction. If I use the SetActorRotation, then it works but then the movement input is off. I.e. pressing up on the joystick doesn't make the character walk forward (the direction they are facing), it makes them walk to the top of the screen.

If I use the AddMovementInput with a direction, then the actor properly rotates and faces the correct direction and everything works fine, but they move slightly with that input, so if I hold the joystick in the direction then they walk in that direction, they don't simply just look in that direction.

I cannot find what exactly is rotating in AddMovementInput so that I can mimic it, if I use/modify controller rotation then the camera moves and it all messes up.

Is there a way to add movement input, but not actually move the pawn/character, but just rotate?

[fair magnet]

since I haven't been on unreal for a while... is there a better way to do this?
Essentially I'm initially setting the rotation of my camera boom and want to prevent the lag from happening on this initial set. Because It would break the immersion a bit if the camera jaggs around after every loading.

[proud sentinel]

add movement input says "usually normalized" does this mean it becomes normalized, or the input needs to be normalized?

tutorials and the fps template show using 2 of these nodes, for forward and right, but then they'd have the diagonal input problem if this node doesnt normalize

[verbal wren]

I am trying to get my rock to throw based on where the camera is/rotate the character with camera while throwing. This is what I have right now, tried setting rotations and such based on the camera but that ended up breaking my movement orientaion completely

[jagged moth]

Can some one help me figure out why this wont connect?

says refrence is not compatible

[frosty heron]

It will tell you the type when u drag the blue pin and why they r not compatible

[jagged moth]

it says chaos wheeled vehicle componet not compatible with chaos wheeled vehicle componet

[frosty heron]

Screen shoot? The pic you have is chaos wheeled vehicle movement component

[jagged moth]

yeah

[frosty heron]

The pic you sent doesn't match with what you said, can you screen shoot instead?

[jagged moth]

i cant because the text goes away one sec tho

[frosty heron]

Might want to consider screen shoot tools. Can't really help with out seeing

[jagged moth]

@frosty heron

[gusty crater]

Having issues with a bit of math or setup here. In my gamestate i have a clock system. On my building i have a "Do Work" function for when a building is placed until it is fully constructed depending on how many workers are working on it. I cant seem to work out how to manage this. Does anyone have any suggestions please? happy to screen share in voice channel below if needed

The way i have it now seems to make it build so much faster than what it should be. I have it set as 1 hour build time with a float of "1" that is why im dividing the clockwork by 60

[lunar sleet]

Win+shift+S

[lunar sleet]

#game-math is a new channel

[gusty crater]

Ahh sorry didnt even see that one

[lunar sleet]

One is Wheeled one is not

[jagged moth]

How would I fix it because all of the bp's use that but I need to get the rpm

[lunar sleet]

I haven’t dabbled with chaos vehicle myself, but it seems you need wheeled vehicle component in order to use that function

So if your vehicle doesn’t have that, you need to add it (or replace the regular one)

[jagged moth]

Im trying to make one and failing miserably

[frosty heron]

Notice the difference?

Read the name carefully

[jagged moth]

I Know that now but the prob is all the bp use the vehicle movement

[frosty heron]

I don't touch chaos vehicle, you will have to figure out the component architecture

Prob want to ask adriel when he is around. He does chaos vehicle stuff

[gusty crater]

Is that bad practice doing it this way? i only want to set it once if true then run the function. Then if it ever hits false, it will need to set it again next time it goes true

Its working, just not sure if its a bad way of doing it

[lunar sleet]

It’s prly fine

[lyric basin]

right, so an oddball question about post process. I have an effect that I want to have gradually effect the screen more or less depending upon a condition. The post process is attached to the player and set. My question is what do I call or grab when I cast to the character and get the post process volume from it? Inside of the character under the rendering materials section there is a slider bar which goes from 0 to 1 and this adjust the intensity of the PP volume, but it doesn't have a name so I don't know what it is.

I have got this so far, but again, not sure what comes out of the post process output pin. If its any context, yes I know I can just make a really big PP Volume and set a trigger, like a collision, to activate and deactivate this effect. The issue with this is that it is a frosting effect on the screen, akin to what you would see happen to a camera in a snow storm. The longer the player is in a certain condition (say, outside in the cold) the more this effect dials in and effects the screen. I also need the reverse to happen since the player could come out of the cold, for example, and the screen would clear up. So that is why a simple "on or off" solution wouldn't work for me.

[frosty heron]

You can always control the post process weight

From the blue pin of the pp , you want to get the setting and set its member

[lyric basin]

so I messed with the blend weight (which is the only option that shows up with 'weight') and that did nothing. Let me try another setup though, a simple on and off to see if it indeed does cast at all.

[frosty heron]

You can always try outside bp first. Add it to the level and play around with the pp

I used timeline for my effect to give a gradual effect

0.5 will be snappy

[lyric basin]

Tried that as well, lol no dice

yeah I wanted to just see if it worked, so i put it low

[frosty heron]

Works for me, again you should play with it outside your bp

Once it work, doing it on bp is cake

[lyric basin]

I know it works, its just getting the nodes right. Again, I know that is the value, since it is the only thing that allows me to adjust the intensity, but its getting it in the BP thats stuck

[frosty heron]

You should adjust a specific blend weight too ( the actual material you want to edit)

Afaik should be on post process material arrays

Don't have editor to check rn

[gusty crater]

Is there a node to set the image to a button but for everything like normal, hovered, pressed etc

[marble tusk]

Maybe try making this a variable. It might be out of scope by the time the Screen event is called

[lyric basin]

you mean use an image on a button?

[gusty crater]

yeah but i want to pass a texture in to set it, but for every option

[frosty heron]

R u changing image or button?

[gusty crater]

or should i just layer an image over the top of a button in the widget

[gusty crater]

There is an option to select image in a default button

[lyric basin]

Thx but I ended up just doing it in the character BP. short and sweet, does the job. I like to try and find alternative ways of doing things to expand my knowledge, but its late and I dont wanna go down a rabbit hole lol

[frosty heron]

R u changing button or image ?

[gusty crater]

The image ON the button

but i want to change it for every type in the blueprint, or is that just a headache? xD

[lyric basin]

you want a different image depending on the state ?

hovered, clicked, etc?

[gusty crater]

same image for all states

[frosty heron]

Make a base class for the custom button then

[gusty crater]

but when each button is created i want to set that image for all of them

[frosty heron]

Define all

You mean for other states

Or other buttons too

[lyric basin]

each state has its own image option....

[frosty heron]

You can change the brush at run time using set style node

[gusty crater]

so each button will have a seperate image, and i want that to apply to all states

[frosty heron]

You can do that in the detail panel then. But if u need it to do it at run time use set style node

[gusty crater]

rogey cheers

incoming spaghet

[frosty heron]

It's only a few nodes

[lyric basin]

curious, how many buttons do you have? and are you using the same image in more than one location?

[gusty crater]

Its a button for each building type that gets added to a grid for the player to choose. So probably close to 100 by the end

each building has a different icon / image

ill just lap an image over in the widget and change that, probably easier

[lyric basin]

ah, I was gonna say, if you are using the same button more than once, you could create a master button and just use that over and over

[frosty heron]

Make a base class for your custom button. Add the functionality. Save your self repetitive work

[lyric basin]

its ugly, but functional. I just made a base class, like summer said, and use it over and over when I need it

[gusty crater]

Thanks!

[indigo zephyr]

hi im trying to get a random line in a cone..

Green is the bp provided (with 0 yaw and pitch), purple is the line just drawing from the two objects

Its a bit off.. Am I misunderstanding something about these nodes?

[elder lodge]

what's it supposed to be doing?
Random line from the cone, but you constrained the randomness to 0?

[indigo zephyr]

Yes to confirm the center point is indeed going to the origin of the other object.

However it is not, the green line in the picture doesn't match yo with the line to the actual object location

[silent stag]

Hey , i using this way for fire automatic rifle but also want to fire rifle with single shot too

[elder lodge]

A Unit vector starts at 0,0,0; is it supposed to come from the Actor? I see Start and End leading off

in which case you'd have to do Start = Actor, End = (Actor + Vector)

[indigo zephyr]

ill try that now

[elder lodge]

Ok; just call FireEvent?

[silent stag]

I did but it's firing with delay with this way

i want to fire also with one click

[indigo zephyr]

Adding after the random unit vector node causes the trace to now go straight up

For reference, the start and end move out ot this trace

[still trellis]

is it not possible to get an interface function to appear as a pure node in Blueprints? It's marked as BlueprintPure in c++ and compiles fine, but when I call it from BP it has execution input/output still

[remote meteor]

its End = (Direction * Distance) + Start Location

[remote meteor]

interface function cannot be pure iirc

[still trellis]

thats obnoxious

[gusty crater]

I keep getting a not valid on "Construction Working On" Im trying to get the one in the array that is the closest. I dont get how it can be not valid though, any pointers please

It loops through the array and gets it, so it has to be valid surely

[manic vessel]

I have an actor that can add a spline component in construct script . that is added to other actors as a child actor component. Im a bit puzzled as to why I cant manipulate the added spline component in the parent actor , but I am able to do so in the world

[still trellis]

What are the default values for Current Distance and CurrentIndex @gusty crater

[gusty crater]

i set them to 0 at the start of this

soirry distance i set high

index i set 0

[still trellis]

hmm, im not super good with breakpoints in BP but you can breakpoint on the Is Valid node and check the array, what index it tried to get, and whether it set a valid reference to that actor

[gusty crater]

Thats just before the loop from the same pic

so on a breakpoint on it, its showing current index as 1, then it says Current Queue Num=2 whatever that means. The array is of a master building type

[still trellis]

that just means there's two things in the current queue array,

okay so the loop is working fine, or at least giving you a valid index

[gusty crater]

oooo actually i think i might know what it is

i think im removing the object without removing it from the queue. i made it the first 2 buildings instant construct

[still trellis]

ah, so you might have a garbage pointer in the array that is pointing to something you already destroyed

in that case, the distance to that pointer will always come back as 0 (i just checked the Get Distance To function), so you'll actually get the bad index consistently lol

[gusty crater]

😄 It works

first lil project trying to do most from scratch so theres many mistakes xD

[silent drift]

Hello! Is there a way to make a "custom only in editor spawn-point"? Currently when I want to test different areas of my map, I move the player spawn-point to that part, but when I forgot to move it back and do a build it of-course starts in the wrong spot. 😄 So I'm wondering if I can somehow make a custom spawn-point that is only used for when playing in PIE? Since then I can keep the game spawn-point at the start, and it just gets ignored when I player in editor and when building the other spawn-point is ignored.

[elder lodge]

click the three dot dropdown next to the play buttons

use Current Camera Location instead

[frosty heron]

There is a node to check which build you are in

[gritty delta]

Curious if anyone has run into this issue. I am in Unreal 5.3. I have a data asset. It's only variable is a struct which contains a display name (text) a few floats and a bool. On begin play, I create object of my data asset type. I then set the struct variable. If I then read the struct variable, it is at it's defaults and not what I set it to. It's almost as if it completely ignores me when I set the struct. For example, this print string returns nothing at all.

[lunar sleet]

Bp structs are broken especially when it comes to live editing. Also, I don’t think you can modify DAs at runtime

[silent drift]

I can't use that since it's a 2d game, and I then start outside of the playable area. 🙂

[silent drift]

Ah, interesting.

I will need to check if I can get that working!

[spark steppe]

i don't see why this would not work

but one big problem here is that you never seem to reference the data asset, which makes it prone to be garbage collected

[pulsar vigil]

Guys i have a weird question when i change something in my bp about my interact system and i start play mode i have half less fps then i wait like 5 minute without changing anything i hit play mode again and my frame are back oO (my interact bp contain tick event with trace and actor component set and when i look with insight it show me that the tick event take all my frame on the cpu)

Can someone explain why the engine look like it need some time to recover my bullshit then it work properly by magic ?
I was'nt experiencing this until i tried to implement my system and object into my environement and not just a blank testing project

[signal perch]

I want to create a widget at the mouse position how do I set the position

[versed sun]

If it is a large BP and if it is open and visable, you can get a FPS hit
Try making sure your main Level Editor tab is what is visible then you press Play

[tight pollen]

hi, Will checking how many people are in a given team and then replicating this value to each player to disable the widget be appropriate in GameState?

[echo storm]

Where does the "Take Automation Screenshot at Camera" node save the screenshots taken? I can't find the path which is displayed in my console log. Also is it normal that I possess the cameras when the screenshots are taken? How can I take the screenshots from the cameras without possessing them?

[dawn gazelle]

It's probably not necessary. If the team value is stored on playerstate, any time someone joins or leaves the game (namely Begin Play and End Play of Playerstates) you could call an event dispatcher on the gamestate that anything that needs to know the counts can bind to, and then the clients can loop through the PlayerArray on GameState and determine the number of players on each team and show/hide the widget.

[ripe lake]

Does this look correct? It's supposed to instantiate an "Equipment" actor, then attach it to the player

[north lynx]

Hey everyone!
Did anyone know how to fix that? I don't understand the problem.

[versed sun]

Click the Moveable button here

[north lynx]

Thank you 🧡

[lost canyon]

Hey, I have a question, I have an event here that If I press tab it opens a widget menu but I want to make it so that if I press tab again It closes, I can't for the life of me seem to figure out how to do it so one press is for open and the other is closed?

I also tried a flip flop

[versed sun]

Try this
If there is already a the widget , remove it
If not , then make one

[lost canyon]

This doesn't seem to work for me cause I am using a player controller for the details and not the BP_Third Person?

[versed sun]

show your code

[lost canyon]

Thats litterally it mate 😄

i'm not a coder btw just an artist trying to figure out what the fuck im doing 😄

[versed sun]

Save the widget to a variable

[lost canyon]

What type of variable?

[versed sun]

Pull off pin and Promote to Variable, it will auto set pin type

[frosty heron]

Nothing stopping you from replicating the code shown in player controller

[gusty crater]

Im making a path building system. I have a "Master Path" with a box collision on each side. I want it to know if it needs to be a straight, t junction, bend or x junction depending on what its hitting. Does anyone know of a tutorial i could look at to wrap my head around how to accomplish this?

[lost canyon]

Done! Thank you ❤️

[lost canyon]

Yeah but I really suck with this 😄 It's my first time trying to mess about with BP 😄

I just see theres a modular way to make menus instead of a single widget you can call widgets and it helps to make things easier to customize and move around 😄

[shy matrix]

I would remove that pin going from the Create Widget to the Remove from Parent node. You don't need it and it looks like it could cause troubles

[dark drum]

Are you working on a grid? I assume your wanting the paths/roads to connect to building?

[lost canyon]

Sorry to bother you I ran into a problem 😄 I didn't have the Set Input mode ot UI only, so when I did that it doesn't close again now 😐

[gusty crater]

yeah its a grid like pattern

[gusty crater]

but for all my building im just snapping my cursor location to a grid size

[dark drum]

Do the paths visually take up a full square or partial? As in the grid size is 2m but the path is only 1m wide type of thing.

[gusty crater]

just starting it, the white cube is my pathway to scale to suite everything, then some box collisions to detect whats on each side. Just need to melt my brain into trying to work out all the logic now xD

i will make it take up the full grid size

Then use some collisions on the edges for all my pathing so the AI cant walk off the edge of a path. Thats why ill need all like 90 bend etc.... i was trying to find a way to have my whole navmesh volume red to start, then use a modifier to make it green only where this path actor is but i dont think that was possible

[versed sun]

hmm, you could put the Remove from Parent code in the widget

[pulsar vigil]

ok i dont understand everything but i think i got what u said

[versed sun]

TLDR: don't have large BP graphs open when playing

[pulsar vigil]

perfect i take note

[dark drum]

Personally, I would have a single path blueprint that has an array/set of all the occupied tiles. (probably an int point) When you add a path, it just adds the grid location to the BP. When you place a building it adds the tile that the entrance would be.

When this happens you then have the path BP check the array to see if the array contains the surrounds tiles. Based on this data, you can then determine what mesh or material needs to be applied at the given location.

This saves you have to mess around with collision boxes or traces.

I've not come across any specific tutorials on paths but what I've described has similarities for a maze generation tutorial I made a few years ago. You can even use the same data to spawn in nav mesh modifier volumes to increase the cost of traversing on tiles that don't have a path.

[gusty crater]

I dont keep track of the whole grid system as i wanted it to always expand depending on the map and not having to generate it. I just have a function that moves my curson position a certain amount to feel as if there is a grid. Would i need to actually track grid tiles for that way to work?

[dark drum]

In a way yea but its easy enough to just get the world location and divide by your grid size and then round.

[gusty crater]

Yeah that might have to be the go

i would still need all the logic to replace and rotate pieces etc though

Which i guess is almost the same point im up to doing it this way

hmmm i wonder if i could just say make the path cube check if its touching another one, and if its not enable one of my collision boxes to block that side off so they cant walk off the navmesh, and if it is touching, disable that collision box. Reckon thatd work?

Then its bugger all logic

[steady night]

for some reson my sound settings aint working, am i missing sometyhing ?

(the save audio BP) is for later ignore that

[gritty delta]

Sounds good I'll use another approach.

[spice smelt]

What are the possible reasons why DestroyActor won't destroy an actor? (in editor mode, called from an EditorUtility)

[lyric basin]

Are you able to access the actor from wherever you are calling DestroyActor?

[dawn gazelle]

You're not supposed to be "Creating Object" of a Data Asset as the Data Asset would already exist, so you just need a reference to it. You technically can modify a data asset at run time, but any details changed won't be saved, so the moment that asset is no longer referenced, you're then working with the default data asset.

[spice smelt]

yeah i checked it's not invalid

[lyric basin]

Could you share a screenshot?

[lyric basin]

What is it doing vs what you expect it to be doing? Is it not mixing the way you want or not playing at all?

[spice smelt]

When the branch that creates the actor is reached the actor appears and everything that uses it works fine. I just need to delete it afterwards

(the second screenshot is the get starting points function that creates the actor)

[lyric basin]

what happens if you put a print node on the Not Valid output?

does anything print on the screen?

just a troubleshooting step, is all

[spice smelt]

nothing, the true branch lights up with debugging

[gritty delta]

Oh I see. I figured that since it was an object, it didn't exist until created. Otherwise how would unreal differentiate between modified data assets at runtime if it's just referencing hard data like a data table.

[lyric basin]

wait, i think i see it

[steady night]

@lyric basin its not affecting the sounds at all, the slider moves with the value but the sounds are always 100% ive set all the sound files to use the respective class
*

[spice smelt]

yeah sry i placed the wrong is valid node for the screenshot, this is what i tested with xD

[lyric basin]

K, is Get Starting Points a custom function? Can I see whats in there?

[spice smelt]

yep, the second screenshot i sent earlier^

ah nevermind, it's a thing that has bitten me already in the past but i keep forgetting ;-;

you have no guarantee on how many times pure functions are called

"get starting points" was being called multiple times, only the last result reached destroy

solution: make not pure

[lyric basin]

yes, that would be it. I was just about to ask if its dumping into an array or something, cuz if there is only one instance it should delete it. But if more than one instance is created, by the time the destroy actor node is reached, only the last instance will be reached.

Though, you could in theory create an array if there is more than one reference and then just call the index you wanna destroy.

[spice smelt]

nah just needed one, ty for the help nontheless!

[lyric basin]

Yup, no problem

[spice smelt]

in fact if i could i wouldn't even instantiate it, i need to access the tree of meshes of a blueprint and copy their materials on an actor in the scene.
Instantiating the bp and destroy it immediately feels wrong but at least it's straightforward

[lyric basin]

how often is this called?

sounds like something that could eat up a lot of resources.

[spice smelt]

Company uses USD, but not in a good way. Animations don't have textures but share tree and names with a pure unanimated mesh.
The Unreal department imports the mesh, gives it materials, saves it to a blueprint. then when they import an animation they wanted a 1 click tool to apply the correct materials

so i traverse the tree comparing names and taking materials from the blueprint to the imported USD animation

[lyric basin]

So looking at it again, I see the volume is being set (to whatever value the Set node is getting) but is the Set Sound Mix node supposed to adjust the volume somehow? I am not that well versed in audio nodes for UE, but I don't see what is actually adjusting the volume, just whats setting it. The Set Sound Mix node just takes the input from the Set node.

[lyric basin]

yeah, I agree with you, that feels wrong.

just sounds like there is a gap somewhere for something to go wrong, but idk.

[spice smelt]

USD mesh to blueprint
USD animation to scene
Apply meshes from blueprint to scene

[spice smelt]

oh been trying to explain them Unreal is a game engine first, not a CG tool.
You can guess how it went 😆

[steady night]

@lyric basin well its a slider

[spice smelt]

What they first proposed was even worse: write a custom json file with the paths to the uasset materials, read it from the animation, like... whelp.
Sry needed to vent

[lyric basin]

yeah, i can totally imagine that convo. I would imagine someone saw a cinematic of what UE can do and put 2 and 2 together to make 5.

[lyric basin]

all good!

[spice smelt]

couldn't have explained it any better!

[lyric basin]

Let me try recreating this on my end. might take me a while, but I've been meaning to put volume options in my game. I will get back to you.

[steady night]

@lyric basin nice ty

[lyric basin]

yeah no problem, just a quick question. this is a widget yes? What did you select from the palette? Was it just slider or something else? Audio slider?

[steady night]

yeah

slider

[lyric basin]

okay thanks.

[lyric basin]

Could you share a screenshot of the rest of that portion of the widget?

[shut compass]

if I have two parameters of the type array. Lets say one is of static mesh soft object reference, and the other is lets say a float. Is it possible to tell Blueprint that when I add an entry to the mesh array it should automatically add an entry to the float array as well?

[lyric basin]

....yyyyyes. I think

[shut compass]

basically like this. but the threshold parm should spawn when I click the mesh entry

[lyric basin]

oh you mean like that. Again, yes it should. You would have to code it (or use nodes) that appended an index to the float array when you add one to the static mesh array.

that should update the UI in the details pane automatcially, but again, it should

[formal narwhal]

With enhanced inputs in ue5 what is the best practice for binding ui triggers ( showing main menu for example) ? And where should the initial keybind be set?

[steady night]

@lyric basinthats basicly it

[frosty heron]

I'm pretty sure you can in cpp. Not sure in bp I'm not aware. If you don't have duplicate mesh in the list, you prob want to use map

[shut compass]

thank you I will see if I a can achieve it in BP before going into CPP

[frosty heron]

There is no call back when adding an entry in bp? Maybe it's possible in bp but I'm not aware. I've used plugins that can modify class default at runtime so I know u can do it in cpp

[lyric basin]

keybinds are set in the Project Settings >> Inputs

[formal narwhal]

I don't use that system anymore, and by bind I mean to trigger a ui element. My question is how to properly trigger ui overlays by pressing a key and then overriding key captures in the widget

[sand spoke]

There is something called get forward vector, that you can make another actor follow you forward. However, is it possible to tilt it by an angle?

[shut compass]

what is the easiest way to inspect return values from nodes in BP?

[formal narwhal]

just get the difference between positions, then use this vector as a heading.

[sand spoke]

What do you mean?

[formal narwhal]

Subtract your target position ( destination ) from your current position ( object that's following), this will give you a vector that points towards the target. Then use that vector to rotate to.

assuming that's what you want.

[sand spoke]

I want to like it point 30 degrees towards the left of the forward vector and then 100 units away at direction

Do I need to use sine cosine stuff?

[formal narwhal]

rotate your forward vector
normalize it then multiply by 100

No there is a rotate function

there is a rotation from x vector that could help you

[sand spoke]

Oh so before I plug in the rotator I can just add the 30 degrees

[formal narwhal]

maybe? Dunno

[winter pebble]

Are timelines you add to your graph stored anywhere in the blueprint or once you delete them are they completely gone/cleaned up? I had some timelines I've since moved to other actors and wondering if I need to do any additional cleanup other than deleting them in the graph

[formal narwhal]

If they are not in the variable outline it doesn't exist.

[winter pebble]

Thank you 🙂

[pulsar vigil]

this is exactly what was happening thx u so much

[minor pagoda]

Is there a way to import FTimespans into datatables with csv?

[steady night]

wich will the move to prioritize ? the location or target actor ?

[dawn gazelle]

It wouldn't really matter in this case as you're giving it both. My own guess would be that it favors the target actor if its valid.

[sand slate]

What plugin makes blueprint lines look so good like this? I always see people using it here and need this, I prefer it over the normal look.

[steady night]

it would if the target moves from the destination if its a long way i suppose

ok

yeah makes sense

[thin panther]

It's called Electronic Nodes iirc

it's about $15

[sand slate]

Ah yea your right, thanks!

[frosty heron]

Depends

You only do it if you are 100% sure that your cast won't fail

Like getting your custom game instance can be a pure function

[solar badger]

Hey all,

Is there an SOP on attaching skeletal weapons to a skeletal character?

Currently i spawn the weap off map somewhere and transform it to the relevant character socket to attach. It works fine but seems hacky....

afaik no one on the internet has ever shown this in a vid lol

[calm thorn]

https://youtu.be/FWaaiwKHdio

[solar badger]

?

Seems to be very clearly a static mesh.

[calm thorn]

what is an static mesh ?

[stuck skiff]

jo does anyone have good blueprint tutorials i could watch?

[calm thorn]

what help you need ?

[stuck skiff]

im new to unreal need some tutorials for blueprint really thats all

[calm thorn]

check on youtube Matt aspland or ryan laley or codelikeme

you

you'll have great beginner tutorials there

[stuck skiff]

thx

[glossy fern]

hello , why can't i pass a variable by referenece inside a custom event in blueprints ?

[rugged wigeon]

I think you can set the input type to be pass by ref with advanced settings

but also, don't do this?

[dire frost]

events are just broadcasts out and have no idea of where it was called from. the fact that epic allows pass-by-reference for events is quite stupid but it's epic lol

just use a function instead. and a timer as a substitute for delays

[glossy fern]

i tried using a normal event and passed the input into a function using a parameter with pass by reference and i get same warning

[dire frost]

the issue is the event itself isn't able to pass params by reference

[glossy fern]

i thought so i just had to make sure ... thank you !

[dire frost]

your welcome 😄

[tired fable]

hello hello, sorry to bother with a question. but does anyone know how to add sensitivity values to analog controls? i wanna have player movement go from a walk or run based off of how far an analog stick is pressed and not based off a toggle.

[gritty delta]

Set the input as an axis instead of a bool. That will give you a float to use. * edit typos lol

[tired fable]

Im extremely new to BluePrint. but i hopefully can rush to a friend to help me do that.

[thin topaz]

Hi, can someone help to guide how, using blueprints, to connect a procedural mesh with a procedural foliage spawner?
It may sound like a procedural channel question but in this channel I am trying to understand in principle how to do such things in blueprints - i.e. connecting things that don't seem to be accessible from "All actions for this Blueprint" menu.
What I have:
BP_chunk, that creates chunks of "landscape" from procedural mesh components - in runtime;
BP_landscape, that is placed in my scene and that sets the chunk parameters for size, noise, scale, etc.
A procedural foliage spawner that is tested (in a different map, based on UE documentation) and works on a UE Landscape component but that I cannot figure out how to make it work on my runtime procedural mesh kind of "landscape". In the BP_chunk, I cannot seem to find any node that I could use to connect to this spawner, or anything that would seem intermediate, to in the end still connect the spawner. Thanks for your help who has a moment!

[random pulsar]

it says to install a component ,where?

[dire frost]

you can start by installing visual studio 2022 instead. and in the visual studio installer choose the "C++ game development" component. also you'll want to install .NET6.0 or above and .NET framework 4.8 or above

[dire frost]

btw #enhanced-input-system makes this was eaiser to make and tinker with later

[random pulsar]

i have it on pc

[unreal epoch]

Anybody know a place I can look to start finding info on creating in engine custom areas? I want to make a feature where you can customize your room ingame with furniture you buy and don't know where to start

[random pulsar]

do i need to install it one more time ?)

[tired fable]

ah okay. i apologize again for putting a question in the wrong spot haha

[dire frost]

oh no need to apologize lol

[dire frost]

no. just uninstall VS19 if you dont need it. and do the other steps that i mentioned before

[random pulsar]

i will just unistall both and install one more time the 22😂

[dire frost]

that's unnecessary

just click the "modify" button in the visual studio installer

[deft spindle]

@dire frost

Could you dm me

[dire frost]

no i prefer if you just say what you want here tbh. that way your issue is more likely to be resolved

[deft spindle]

No not like that is like a job thingy

[random pulsar]

if i want to develop for android i also need to select from that list something?

[dire frost]

oh well im not available for hire right now 😅

[deft spindle]

Oh oj

[dire frost]

i have not made games for android with unreal but afaik you dont need to.... maybe you'll want to move your questions over #programmer-hangout

[random pulsar]

and also something,do i need to tell unreal to use visual studio 22 somewhere?

[dire frost]

should in the project settings

[random pulsar]

the build is successful but something strange happened,the bird is not rotating at the same speed when it dies and the jump decreased by x3

anyone had something similar?

it may be cause of delta seconds?

[atomic saddle]

Hello i want to make the player go on top of the object but still have the same x or y value how can i do that ?

[pulsar vigil]

what do u want him to do concretely ? sit on it stand on it ?

[atomic saddle]

stand on it

just teleport on top of it

[pulsar vigil]

then u can make a scene component in the bp of it that will serv as target and u set the position i suppose i m actualy doing the same thing but i use motion warping and root motion animation

i can explain more if u want

[atomic saddle]

please do

[pulsar vigil]

by setting a scene component in the blueprint of the greenthing u set a component that have his proper transform, if u get it in ur bp_character u can set the position of ur charazcter on it

[warped juniper]

Just a question, is this teleport you want a specific actor always? Or do you want it to be a repeated element...?

[atomic saddle]

Wdym?

[warped juniper]

Well, is this cylinder the player can teleport on top of a single thing across the entire game that lets you do that?

I'm not very sure of how the mechanic works or how do you want it to happen, sorry

You can always just tell an actor "get this actor and teleport me to X" but it's a very rigid system.

[thin topaz]

How to manually place a mesh in my scene if it is generated in a blueprint in runtime?

[dire frost]

just put the mesh generation code in the construction script

[atomic saddle]

its a cylinder that the player can teleport on top of

[thin topaz]

Just copy paste no matter how big it is?

[dire frost]

if it's slow code then i recommend calling the code via a call-in-editor event

[warped juniper]

Okay, so you want the game to allow you to use multiple cylinders to teleport on top of?

[dire frost]

so it wont lag everytime you drag the bp

[warped juniper]

Or is there just a single cylinder in the whole game that lets you do that

[thin topaz]

I copy pasted and nothing happens in the scene..

[dire frost]

in the construction script?

[atomic saddle]

yes

[dire frost]

oh yeah bp doesnt allow spawning actors right...

[thin topaz]

yes. then compile, save, went to my scene, nothing.

[dire frost]

yeah then just use a call-in-editor event

[warped juniper]

Okay then, my suggestion is that you use an Interface

Since you want to have several actors with overall the same behaviour of interaction

[cedar sky]

Small question

Does the "Ongoing" Output fire an Event every Tick the key is held?

[warped juniper]

https://docs.unrealengine.com/5.2/en-US/enhanced-input-in-unreal-engine/
Taken from the UE docs.

[cedar sky]

according to my understanding, it should work

someone else in a tutorial i found did this by adding a "for each loop with break" on trigger output

[lunar sleet]

Next time use #enhanced-input-system channel, it’s more specialized. As for your question, when you have a hold trigger of say 5 seconds, and you actuate the button, the event pins fire as follows: Started on actuation, Ongoing while actuated while not having reached the 5 seconds, Triggered after 5 seconds of hold (at which point Ongoing stops firing), Completed when released after the 5s, Cancelled if released before the triggered fired

And yes, both triggered and ongoing tick away while their respective stages are active

[tribal gazelle]

Just trying to understand the best practice when trying to achieve "tonnes" of pickup spawns. Currently, I have a "Pickup Manager BP" which loops through all "Pickup Spawn Point BPs" and then spawns a "Pickup Base BP" with a random item. I am estimating to need around 1,500-2,000 of these pickup spawn points and was wondering if it's even going to be possible to loop though all of those actors by the time I reach that many? Should I be doing it a different way? Or is there a more efficient way of doing this? Like doing it all within the pickup BP and manually placing them down instead of spawning them via a manager?

I also want to loop through them all every 45 mins and destroy the ones that have not been picked up yet and then respawn them all again.

I looked into the loop limit for UE and it's like 1M loops.. but can the engine handle thousands of loops is what I am asking?

[lunar sleet]

The engine can

[formal narwhal]

That's not what pure cast does. Pure casting a function returns a value without execution pins but the value is revaluated everytime it's called.

[lunar sleet]

Whether you should be doing that in bp is another story

[formal narwhal]

wait i might be conflating it with something else

my bad I was thinking of pure functions

[lunar sleet]

I’d just delete your msgs at this point

[formal narwhal]

Nah

It's literally free not to be toxic but you do you

[abstract mango]

Quick question

When I switch the skeletal mesh of my blueprint, the material slots of the first mesh somehow overwrite the materials of the second skeletal mesh ... is there a way to change that without switching the materials in the blueprint for each new skeletal mesh I'm putting in there?

Since actually, the car body is only a cosmetic, and it should be switchable on that blueprint, instead of making about 120 blueprints for all the different cars

[lofty rapids]

it looks like instead of "switching" you are just putting one over the other

[frosty heron]

Everytime you change the skeletal mesh, loop thru the material and set material to none. This will revert the material to w.e the new skeletal mesh have

[wraith loom]

Hello, I have blueprints which generates a very large array. I want to set the generated array as the array's default value. Is this possible?

[solar badger]

Hey all,

Is there an SOP on attaching skeletal weapons to a skeletal character?

Currently i spawn the weap off map somewhere and transform it to the relevant character socket to attach. It works fine but seems hacky....

[lusty hedge]

can variables be called like this ?

the guy in the youtube video doesnt connect the pins

item id is just being called

without being set

[frosty heron]

Can, what it does behind the scene is promote it as local variable

[lusty hedge]

but it doesnt show up as a local variable

is it still one anways?

[frosty heron]

Yeah

[lusty hedge]

cool

id probably never do it this way

too confusing

doesnt seem readable

[frosty heron]

I seen ppl do it this way, I got used to it and do it my self from time to time

When I have to drag too far and it's unnecessary to do so I just get the variable like what your pic shown

You should prefix the locql variable with L_ for readability

[lusty hedge]

when i have to drag too far i usually just make a variable and set it at the beginning of the blueprint

but i suppose it already exists

[lunar sleet]

Yeah I had to learn that too, input vars on a function already exist in it so you don’t need to promote them. It looks weird but you get used to it

[solar badger]

is this getting skipped cause no one actually knows?

is attaching two skeletal meshes ancient magic

cause i can do it, I'm just kind of hacking it...

wondering if there is a better way

[frosty heron]

Wats the value of the array?

[frosty heron]

If someone can help, they prob will. Personally I never attach sk to sk

[lunar musk]

I spawn an actor and i attached to socket GripPoint. How can i get socket location in animbp?

[solar badger]

well its not really a workflow/practice thing

You cannot make an animated weapon without it

[frosty heron]

Just saying I never done it, so can't help you pal

[solar badger]

or attach anything with an animation to the character at runtime

[solar badger]

oh never have, my bad

I thought you were implying its bad practice some how

[frosty heron]

No no

I believe a pistol or rifle would need to be skm

Soo far I only deal with swords

[solar badger]

I can do it no problem, i just dont like that I need to spawn the mesh on begin play first, and then transform it instead

[abstract mango]

All I do is switching out the Skeletal mesh Asset reference

[frosty heron]

You just get a ref to your skeletal mesh then grab the socket location?

[frosty heron]

Addressed the problem for you

You can reset by looping thru the material and setting it to none

Works for me

[lunar musk]

i don't have an skeletal mesh on characterbp

[abstract mango]

now, if I as a beginner now would know how exactly that works, that'd be helpful xD

[lunar musk]

I have a skm on weapon bp

[frosty heron]

Have one then? Abp Job is to read

[frosty heron]

After you change the skeletal mesh, get materials and do a for loop

For every loop set material to none, and the index to the array index

Done

[abstract mango]

Do they have to be dynamic materials?

[lunar musk]

Maybe, but i spawned a weaponbp and attached to socket. I wanna get a ref to that weapon bp

[frosty heron]

Nope

[lunar musk]

So i can use weapon skm

[abstract mango]

good ^^

[frosty heron]

Then make a ref to w.e you need and initialise them

You should have a ref to your custom bp character in your anim bp

[lunar musk]

I have it

[frosty heron]

From there you can access your weapon bp or w e it has

[abstract mango]

Wouldn't it be smarter to do the for loop for the mats first?

Or won't that make a visual difference?

[frosty heron]

You have to do it after you change the skeletal mesh because u want the materials to fall back to the latest skeletal mesh

I mean atm u only change the skeletal mesh, didn't give any instruction to change the material

[lunar musk]

I tried this and not work

[frosty heron]

Make sure u don't get error

Any accessed none?

[lunar musk]

Nop

[frosty heron]

Ensure that you have the socket in your weapon mesh

Other than that I don't know. It should work

[abstract mango]

true

[lunar musk]

That it's my code

[frosty heron]

You have to play in pie

[abstract mango]

ok I'll test that later

[frosty heron]

Then check if u get accessed none or not after exiting pie

[lunar musk]

That valid check return me not valid

That's the problem

[frosty heron]

Well there u go

[lunar musk]

Maybe bad initialization?

[frosty heron]

Set the appropriate variable

More like never initialised? Show where you set the weapon bp

Weapon component*

[frosty heron]

I would say it can be null at the start

[lunar musk]

Why?

[frosty heron]

You shouldn't need to make a weapon comp variab

[frosty heron]

I dunnoe, don't have access to your project

You already have ref to the player anyway

So don't need a separate variable for weapon comp

Simply tpschar-> weapon component

Try that

[lusty hedge]

i need the player BP to run a function on a WBP

[lunar musk]

It works

[lusty hedge]

but i cant seem to figure it out. casting and interfaces require a target

[lunar musk]

Thx

[dire frost]

just use GetPlayerCharacter?

[faint pasture]

how does the PlayerBP (whatever that is) know which widget to run the function on?

What are you actually trying to do?

[lusty hedge]

the DisplayInventoryFunction is located on the WBP_Inventory.. im trying to call that function from the players blueprint

[faint pasture]

Which actor actually creates that widget?

[lusty hedge]

The player

but nothing happens

[faint pasture]

you gotta add the widget to viewport

[lusty hedge]

oof

i always forget that

[faint pasture]

If that's the players PAWN make sure to say so

player doesn't mean pawn

[lusty hedge]

im not sure what that means

but it works now

[faint pasture]

Pawn is the thing you control

[lusty hedge]

thats set in the gamemode right?

[faint pasture]

https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Framework/

Gamemode defines the default pawn yes

The closest thing to "the player" is probably the playercontroller

[lusty hedge]

wouldn't that be the player character

isnt it a direct reference to the player BP

[faint pasture]

Character is a subclass of pawn

"Get Player Character" will get their pawn if it's a Character

Player BP doesn't make any sense, nobody knows if you mean PlayerController or their Pawn. Just call it Pawn or Character if it's one of those. All Characters are Pawns tho.

[sand slate]

Is there a way to change the values in a timeline with a input?

[faint pasture]

Possibly not, are you trying to scale the whole timeline?

A common approach is to have the timeline go from 0 to 1 and then you multiply that by whatever on the output

or map range

[sand slate]

oh yea ofcourse maybe thats a better way

thanks!

[abstract mango]

@frosty heron I seem to do something wrong here:

[frosty heron]

Connect set material node from the loop body exec pin

Not from completed

[abstract mango]

still doesn't work

[frosty heron]

Show pic

[abstract mango]

there ya go

[frosty heron]

Did you do it after you change the skeletal mesh?

[abstract mango]

yes

[frosty heron]

Try print string on completed to make sure it runs

[abstract mango]

wait a sec lol

[stuck dragon]

Hey, when you make a varialbe public how can I access it through another blueprint?

[frosty heron]

By Getting the instance of the class

I would recommend watching Matthew blueprint communication video

[stuck dragon]

awesome, thank you i'll check it out

[abstract mango]

You are awesome @frosty heron

[pallid nest]

hey guys , i have this code (L1_1) that basically on beginning overlaps displays a widget and on endoverlap removes the widget through a boolean and it works perfectly. My problem comes when I duplicate this BP (L2_2) as the cast fails. Is this because I need to do a child the duplicated BP?

[warped juniper]

Just a random idea, maybe you could find the actor rotation and offset the control accordingly?

So if the actor is standing on a wall at 90 degrees from the world floor, then offset the movement vectors 90 degrees in that direction

[prisma cedar]

Thanks! I'll try it out

[empty mural]

If I have an actor component and it's replicated, do I also have to replicate the event that sets the variables, or should I be able to read the variables from other clients without pushing it all through the server?

[lyric rapids]

How do i refrence a scene camera from another actors blueprint

[faint pasture]

however you want

What and where is the camera?

just a camera in the world?

[true valve]

So I take MoveForward value and run it through FInterpTo and set the result to a variable called FooBar. I'm facing a challenge where I need to reset the variable FooBar to zero when switching between -1 and 1 value from move-forward.

[faint pasture]

check sign of input

vs sign of current interpolated value

[true valve]

FInterpTo output uses other math to create a value which is not -1, 0, 1. So I can't use that.

[lyric rapids]

yeah its just a camera in the world

[faint pasture]

You can get actor/s by class if that works.

quick and dirty

[lyric rapids]

ive tried that but it doesnt show up

[faint pasture]

what class is the actor?

[lyric rapids]

a camera

well camera actor

[faint pasture]

k so get actor by that class, anything?

[lyric rapids]

then how does it know which scene camera i want tho

[faint pasture]

that's up to you

[true valve]

Any idea? #blueprint message

[faint pasture]

explain in plain English how the camera should be chosen

[faint pasture]

Show what you're actually doing

[lyric rapids]

ive got two scene cameras and i want the 2nd one to be stored as a variable

[faint pasture]

you can check sign of a float

[faint pasture]

so how do you pick which one is the 1st and which is the 2nd?

[lyric rapids]

i dont its just my 2nd camera in the scene

[faint pasture]

I'd put them both on 1 actor if every level has 2 cameras

or use tags

what makes it the 2nd?

how many cameras are in the scene in the editor?

[lyric rapids]

2

[lyric rapids]

nothing im just speaking in terms of the order i placed them in

[true valve]

The top connection is moveforward value. FInterpTO saves it to Rotation variable. I need to reset Rotation to zero everytime, moveforward value switches from -1 to 1 or viceversa. The reason when switches I want the calculation to start from 0 instead of the currentl stored value.

[faint pasture]

then do that

if target and Rotations signs don't match, then Rotation = 0

[true valve]

How? Since the connection is always on

Rotation value is 90 or 100 or 140 stored in a map.

I just want the FinterpTo to go from 0 to 90 when switch happens

[faint pasture]

show the rest of the code around this

[faint pasture]

You'll need to save something frame to frame

if you save A then you can check the sign vs last frame

[faint pasture]

is Temp Val an actor or local variable?

[faint pasture]

check the SIGN of them

[true valve]

float

sign function

[true valve]

But it will return the same as move-forward value

[faint pasture]

gotta compare it vs last frames

they will match all the time except when you cross 0

If SignLastFrame = SignThisFrame -> normal
-> Rotation = 0

[true valve]

I only found this function

[faint pasture]

probably round that

or use NearlyEqual

[tired fable]

would i be able to use a get analog input modifier as a means for my player movement to detect different speeds? for walking to running for example?

since im not trying to make running a toggle

[faint pasture]

You can just get the axis value

unless you want an actual event to fire from the input system

[red berry]

Whats the blueprint code to determine if a Material Instance can have its color changed or not? i.e. if the MI is the type that's on the left, instead of the type on the right? I tried using "GetParameterInfo" node with parameter names like "Color", but its not working.

I need a way to determine if a MaterialInstance (not a dynamic one, the default constant one) has a TintColor or not basically.

[tired fable]

thats what i was figuring (although im not sure where to tie it in my movement sorry new to making games haha but ill figure that out with my friend :D)

[faint pasture]

I'd do it based on results instead

[tired fable]

like trial and error?

[faint pasture]

anim bp just blends between animations based on speed

if you're talking about the animation side of things

[tired fable]

i need to have the player character movement determined on how much the analog is pushed

[faint pasture]

It is by default

[tired fable]

like a slight tilt = walk and then a full push is run

[faint pasture]

give it less input, it goes less

[tired fable]

(for some reason it just goes all the way to the max speed)

[faint pasture]

show your input -> movement setup

[tired fable]

ok give me a moment

im assuming youre talking fromthe blueprint correct?

or i mean the event graph?

[faint pasture]

yeah, the bit of code that goes from your input action to AddMovementInput

[tired fable]

if my understanding is correct you mean this haha. i apologize again for my lack of knowledge since im new to making games but i have goals to make this game 😄

[faint pasture]

print the x and y from IA_Move

if they are analog then you'll have to just tune stuff in the movement component

[tired fable]

oki

would you be opposed to meeting me in one of the voice chats? if thats alright? i understand if youre busy

[faint pasture]

I'm at work right now, sorry

PM me and i'll hit you up when I'm home

[wraith loom]

What do you mean by value? It holds vectors, about 2 billion of them.

[tired fable]

sure thing!

That's editorBP making an asset or using a save-game territory

[remote wasp]

Hi, I have an issue
I have a pawn with an Ability System Component and an Attribute Set
On begin play I try to access the Attribute Set
But on certain pawns, the Attribute Set is not valid. After digging a bit, I found out that pawns that are spawned in the level have valid Attribute set, but not pawns that are placed in the level
How do I fix this?

[faint pasture]

dafuq is you doin

[faint pasture]

#gameplay-ability-system

[wraith loom]

What do you mean by making an asset?

[remote wasp]

already asked there, and it's more of a general Unreal question than a question specifically about the GAS

[faint pasture]

https://docs.unrealengine.com/4.27/en-US/ProductionPipelines/ScriptingAndAutomation/Blueprints/

[remote wasp]

why is a member initialized when the actor is spawned and not when it's placed is my question

That's a GAS specific problem it sounds like

probably isn't serializing? Maybe ask cpp

[remote wasp]

alright I'll try

[faint pasture]

@wraith loomWhat are you doing that uses 2 billion vectors anyway? Vector field?

that's 24 gigs of vectors.......

48 if they're doubles

[wraith loom]

Galaxy. Anyways, I looked at your link and I don't understand how that helps me make a default array.

[faint pasture]

You'd need to make an editor BP that can make an asset for you, which would have the stored array within it

you're waaaaaaaaay off into fancy pants territory though, storing 2 billion of anything is going to be a nightmare

like, most people won't be able to fit it into ram

[wraith loom]

it wont be in ram

[faint pasture]

yes it will

[wraith loom]

it won't fit, so it won't

[faint pasture]

if it's just on an array in some asset

well yeah

Have you got it to actually run to 2 billion in Unreal? I'm sort of mind blown that it would even do that

[faint pasture]

If it's being generated by a procedural algorithm you'll have to do something different

No Man's Sky doesn't ship with the galaxy as data, it ships with the code to generate parts of the galaxy

[distant canyon]

You're right there, so if you're lucky your games process will just get terminated by the OOM (out of memory) killer

[faint pasture]

540 stars per pixel for a 2560 x 1440 screen

[distant canyon]

realism

Actually that's not very realistic, isn't there that tidbit where if you hold a grain of sand in front of you toward the sky the area it covers your view contains 1000s of galaxies

[hardy swallow]

Sure, but because of gravity warping light, and light itself being slow compared to the size of the universe, you won't see that many anyway

[wraith loom]

I can't find any editor utility blueprint tutorials for some reason

[wraith loom]

what editor utility blueprint parent class should I choose?

[hardy swallow]

Not positive, but I think they're talking about a blueprint which exists in your level, but you only use while in editor by running functions set to run in editor

[faint pasture]

you are way outside of tutorial land if you want to generate and save 2 billion of anything

start by making an editor utility BP that can make an asset with a bool in it

[distant canyon]

How are you going to generate the 2bn points?

[thin panther]

honestly you're way out of bp land for 2 billion of anything

[faint pasture]

I can't make a galactic gravitational sim in BP? scam

[distant canyon]

inb4 foreach i in 2000000000 do star

[thin panther]

I heard the simulation we definitely all live in was made in BP :P

[faint pasture]

Could probably do it with a million stars in Niagara

the O(n) would be mental though

[wraith loom]

Is there a node to make an asset? I searched asset and couldn't find anything obvious.

[thin panther]

yeah. Even in C++ land your iteration time for 2 billion of anything is insane.
Even pulling all the tricks out with cache alignment, simd etc

[faint pasture]

Do it with a SaveGame first

but no, you won't be storing 2 billion

start with 200

[quartz kayak]

Why can't I delete any components here?

[distant canyon]

That's a c++ component

[lyric rapids]

how do i switch from a camera on my player to a static camera in the scene

[faint pasture]

Add a camera to the scene -> use it (however you want)

I'd start by not having a camera on your pawn at all and seeing if it'll automagically use the one in the scene

might do that

[distant canyon]

Camera manager is a good habit to get into using as well

At least I find it helps when using multiple cams

[distant canyon]

I don't think he should be pursuing that, procgen would be a much better use of time if he wants galaxy sized simulations

[thin panther]

If you want true galaxy sized simulations, you also probably want a couple tens of millions of dollars in r&d money

[quartz kayak]

Not particularly helpful

I can find the cpp and h file for the parent class and edit that

[distant canyon]

You can't delete a component created in c++ from a blueprint

[faint pasture]

You can't get rid of components that come from a c++ parent class

[distant canyon]

You'd have to modify the base c++ class

[quartz kayak]

but there only seems to be a uasset file for this particular BP

[faint pasture]

is that the default 1st person template actor?

[quartz kayak]

Yes

[thin panther]

You can't delete anything that's inherited in a child class.

You also can't edit the cpp and .h source, because in a launcher build it's read only, and you'll permanently screw every single thing derived from a character. Well, in this case every single third person project but you get the gist

[faint pasture]

use Character instead

Object -> Actor -> Pawn -> Character -> YourBPClass is what you want
Object -> Actor -> Pawn -> Character -> WhateverThatParentClass Is -> YourBPClass is what you have

[distant canyon]

What class does it derive from? Should say in the top right corner

[quartz kayak]

<project name> character

[faint pasture]

Either edit that if you intend to have a project specific C++ character base class or don't use it and reparent to Character

[quartz kayak]

I should be ok to edit the parent class I think given that it seems to be project specific

[faint pasture]

How do you have a C++ parent class and not know?

[thin panther]

You don't want to edit the firstpersoncharacter

Nor can you anyway

(at the moment)

Just derive from character, as Adriel said

[distant canyon]

If they have a <ProjectName> Character they probably can modify it, but not a good idea unless sure it won't break something else

[thin panther]

I'm generally just saying it's not a good idea because they don't seem familiar with the way things work. And editing things like that when you're new is not a good idea

Though I'm not sure where they got this from, because that is the default first person character

So <project name> character must derive from that

[distant canyon]

Ah yeah, I'm not familiar with the default template classes

[thin panther]

Unless someone for a pack of whatever has just ripped the first person character code 😆

[distant canyon]

Moral of the story: don't touch it and just use ACharacter as you suggested

I was thinking it might be their projects base character class and have things for project-wide setup (e.g. GAS, AIPerception, VOIP, etc)

[elder lodge]

What're you trying to do such that a billion values actually need to be referenced or sensed in any form?

[lunar sleet]

He said he’s making a galaxy

Basically KSP2 🙃

[hardy swallow]

I feel like the obvious solution would be octtrees, but I'm probably missing something

[wraith loom]

I'm trying to make it so that players can build in each star system, so I think I need a sort of "master array" for everything to reference to.

[hardy swallow]

You can have most of that sitting on disk until you need it

[elder lodge]

Are you reinventing no mans sky

[wraith loom]

I know

[elder lodge]

But why before it's built?

[wraith loom]

It's a multiplayer game

[elder lodge]

Couldn't you generate new planets as they actually get interacted with? Procedurally?

Same question
Just wait until they're generated to store them

Add server space as needed

[wraith loom]

I don't think that works, because I need to make a map, and I think generating stars live is too taxing

[distant canyon]

@Zap even better, always procedurally generate the planets and just store deltas

[sly nymph]

ue5 thinks I have an infinite loop, but its only infinite as long as it doesnt reach its assigned max value (which it has) and I dont know how to get around it

[hardy swallow]

In blueprints, yes, it's a million iterations iirc

[wraith loom]

The people in the forum post have "create asset with dialog" and "create asset" nodes, which I don't see. I got the LE standard library plugin and that doesn't make the options for those nodes show up either.

[distant canyon]

Do you "Get Asset Tools" first?

[wraith loom]

ah thanks, I didn't drag off of it
