my brother in christ, do not spaghetti. 🙏

[limber parcel]

ahmen 🙏

[faint pasture]

Start by lining things up instead of dropping spaghet all over the place

also break your stuff out into function if it makes sense.

If you see a blue ref line going all over the place, that's a clue to make a variable.

[naive stag]

I unfortunately can’t do that

[faint pasture]

If you're saying "but I don't want my BP full of variables" then that's a clue to make a function.

[desert juniper]

much unfortune

[faint pasture]

@naive stag
Whenever you cross over a chunk boundary

Update NeighboringChunkCoordinates (should be like 9 or 13 or 16 or 25 2d int vectors or something like that)
then
For each Coordinate in NeighboringChunkCoordinates, check if one of the CurrentChunkActors has that same coordinate (that's the chunk that is still valid). If so, move it to that index. If not, spawn a new ChunkActor. Once done, destroy all ChunkActors left over. Or you can do the destroy loop before the spawn loop, however you wanna do it. I would do it in 2 loops, first one moving/destroying current ChunkActors, then the 2nd filling in the holes with the new chunks.

Either way, you'll have a much better time using an array NeighboringChunkCoordinates to keep track of what chunks SHOULD be spawned. The test for if a ChunkActor is still valid is just Find(NeighboringChunkCoordinates, ChunkActor.MyCoordinates)

Super simplified, if you had a 3x3 visibility zone and were standing on coordinates (3,2)
NeighboringChunkCoordinates = ((2,1),(3,1),(4,1),(2,2),(3,2),(4,2),(2,3),(3,3),(4,3))
And your ChunkActors would have 9 actor pointers in the same layout.

[naive stag]

Thanks a lot for the idea, I’ll try it out tomorrow and I’ll let you know how it went and if I had any problems with it.

[limber parcel]

uhh but i didnt want to clutter everything with variables

[faint pasture]

#blueprint message

[limber parcel]

rather macro than function though

i dont see a point in function libraries so far, they only have very niche use imo

[limber parcel]

can u give some example where functions are actually better than macros?

[faint pasture]

A macro is just a copy paste.
A function has local variables and a return and call stack and all that.

[limber parcel]

but where would i actually use a function library? so far im doing everything related inside my actors or whatever, and macros

and components and interfaces

[lapis ridge]

Hey guys, my animBP's responsiveness seems to scale with the tick interval on my player. At tick interval 0, it doesn't respond at all. At tick interval 1sec, it does fully. Does anyone have any advice?

It's using a control rig btw

[pine trellis]

Thanks @dawn gazelle ! that worked!

[severe skiff]

@faint pasture why are you called "stop watching tutorials"

[tight schooner]

Probably cuz the most hopeless type of question that appears here is "I'm following this tutorial link to 40 minute video and when he does the thing, it works, but when I do the thing, it doesn't work. Why???"

Not a great way to learn if you blindly follow them for too long

[tight vale]

Is the randomize transform missing from Unreal 5? wiki make it seem like it should be there

[icy dragon]

Because often times YouTube tutorials sucks and promoting bad practices. Doesn't mean there aren't good ones, but newbies won't know any better.

Also the lazy question seanny mentioned.

[candid geyser]

Okay! So I have the mantling system working for the most part, buuut there is one thing that I dont quite have down yet. So, im not 100% sure how to explain it, but I have it so that in order to be able to always mantle ON TOP of it instead of potentially falling off after mantling, it moves the player close enough to the top, so that the animation can pull the player up the rest of the way. Problem is, one of them will move the player partially inside of the wall enough to where the camera will glitch for a couple frames. Any idea how to prevent it?

[limber parcel]

because the unreal tutorials i watched so far are retarded and mostly teach u how to NOT make a game lol

like most of these guys spam casting everywhere like they never heard of interfaces or components

[candid geyser]

A lot of the tutorials WILL show you how to do things, and they WILL work, but many of them will do it the wrong way. I once spent an entire day making an advanced dialogue system only to learn in this server through @icy dragon and someone else that the way I was doing it was not at all practical

You CAN use tutorial if you really want, but I would advise at least spending a while trying it yourself, as most tutorials will do it in an impractical fashion

[tawdry surge]

Trick to tutorials is watching several and not worrying about clicking along, but stealing a concept or two

and unrealengine.com learning section is curated and usually decent

[faint pasture]

Because following along with tutorials is bad

[candid geyser]

Coding something into the game is a lot easier if you think about what you're trying to add from the computers point of view.
For example, if you wanna add a feature where you can fast travel, DO NOT think about "hmmm how can i do this" or "hmmm where do i start"
Instead, think about the information the game needs to be able to execute the task like "Where does the computer need to take me" and "How does the computer know WHEN to move me there" and so on

If you can think about what kind of information the computer needs to execute the task effectively, then you will already know exactly how to do something, and where to start

[tawdry surge]

almost like your giving it instructions

[faint pasture]

Exactly. Start with the data.
For fast travel, you'd think "well, it's sorta like a save/load operation, can probably use a lot of that functionality"

[candid geyser]

(Obviously to implement a fast travel system there is a myriad of things the computer needs to know)

[candid geyser]

Im pretty sure its EXACTLY that

[faint pasture]

Yeah, someone should make a set of instructions. And then a language to make it easier to write them. And some sort of thing to compile the language into those instructions. IDK if it's worth it tho.

[candid geyser]

This I actually ironically learned from @faint pasture himself, and how ineffective it is to just think about what you can do to get something done

[tawdry surge]

I tell my students to imagine you want to explain something to your dumbest friend who also doesn't speak English

[candid geyser]

Especially when making the mantling system and he told me I could start by finding out where the top of the object is and so on

[faint pasture]

Exactly. Computers are REALLY REALLY REALLY dumb, they don't infer anything or read between the lines AT ALL, but they do EXACTLY what you tell them to, very very fast.

[candid geyser]

That was kind of the "aha" moment where I realized you have to already know what information the computer needs so that it can actually execute the task in question

[faint pasture]

A good term for that sort of thinking is "Start with the data". Start by thinking about what the data involved in whatever you're trying to make looks like.

[candid geyser]

Yeah

Always the data, because if you're trying to move a component from point A to point B, it needs to have the data that which point A and B is located

And it needs to know how fast to move it, and so on

[earnest finch]

Are youtube links allowed on this server? (It's about what tyou are talking)

[candid geyser]

I think so

[candid geyser]

Read the rules and make sure

[earnest finch]

Didn't see anything regarding that, so I'm gonna take the risk. As a programming teacher, I love to do this kind of things in my first day of class: https://www.youtube.com/watch?v=cDA3_5982h8

Basically, the computer will always missunderstand what you say. Think how you would explain to a 3 year old something, and that's how you should talk with your computer

[candid geyser]

Also, to anyone who has an idea, to shorten this up, is there a way I can make sure the player doesnt go inside or through any collision while being moved with a "Move Compnent To" node?
I know that to do that I would need to have a way for the computer to know exactly where the object is, in order to avoid going inside of it, but im not very sure how to go about that.

[candid geyser]

Yup. A single typo and the computer will have NO idea what you just said to it haha

You have to write the code as perfectly as the computer will execute it

[junior hedge]

is there a way I can make it so something will not force the player to move?

for example I have a coin that should dissapear when it is collided

I want it to still be collided but I don't want it to be a solid block I guess you could say?

[trim matrix]

Change the collision preset?

[junior hedge]

what to change

[trim matrix]

Even if I told you, you wouldn't get what I told you to change

Read a bit of docs about collisions

[daring whale]

I've put together some meshes using the modeling tool. Is there a blueprint i can use to make Unreal treat that as one united object?

[junior hedge]

For better debugging, is there any way I can split a string up to make it detailed? For example VELOCITY VALUE (velocity)

[thin panther]

Format a string beore you print it

Print "Velocity: " + velocity

[junior hedge]

i dont get what you mean

also what do UI's inherit from? for example my NewGameState inherits from Get Game State

[mental trellis]

It doesn't.

[limber parcel]

how to use local variables in a macro library? i made this but it doesnt seem to work

basically i want to calculate weight of my resources and then output it

[rough blade]

where are the settings for physical animation profiles?

[limber parcel]

ask in #animation ?

[rough blade]

can do - wasnt sure if that counted

[limber parcel]

guess u will have more luck there

[limber parcel]

guess im using the local variables wrongly but i cant really figure out how to use them

[mental trellis]

Macros can't use local vars, they don't really have a "scope" They aren't functions. If they're anything like cpp macros anyway.

[tight vale]

Let me introduce you to JavaScript

[limber parcel]

i replaced the local shit with an input now but its still not working :/

[mental trellis]

Maybe your code is just wrong then.

[zealous moth]

@candid geyser what kind of object? Skeletal mesh?

Because you can use a physics asset for that

Otherwise use blocking volumes or blocking colliders

[tawdry surge]

i dont get what you mean
@junior hedge there's an append node
Just be sure to shift+enter in the entry fields to add new lines

[unique turret]

I have a construction script inconsistently firing. I have a BP actor placed within another actor. I need to cast to the child BP to change a static mesh component. It works in the editor the first two times I toggle it, then it stops changing the mesh. Even when testing the level, it won't especially update to the correct mesh.

It's a case of it working well-enough, but it is for a client and I'd prefer it worked seamlessly. Any ideas what would cause a construction script to fire inconsistently?

[junior hedge]

Thank you

[cyan bone]

Im trying to possess a ThirdPersonCharacter in a TopDown Template. I imported a ThirdPersonCharacter to it using the add/import green button.
Then i made this blueprint so that i possess the character when i click on top of it. But it does nothing.
How can i make this work?

[trim matrix]

Does nothing as in.. your print string dosent even print?

or does nothing as in, does not posses

[twilit heath]

i was just starting to type that same question

https://gyazo.com/fb7b20b1c720f96a09f798b1d5de88b3 if it doesn't you might want to find and configure this part of your PlayerController in its class defaults

[trim matrix]

yes, make sure EnableClickEvents is checked

[tawdry surge]

@unique turret do not use child actor components
They are unreliable

[trim matrix]

Just a side note as well though, you do not need to cast to TopDownContoller to use the posses function.

You can use a normal PlayerController reference to run that.

[cyan bone]

It doesnt print anything. But it does print with a topdowncharacter. so maybe its something in the controller?

[trim matrix]

EnableClickEvents is checked?

[trim matrix]

You said TopDownCharacter?

Do you mean TopDownController?

[cyan bone]

it prints message if i click on a TopDownCharacter. But it doesnt print if i click in the imported ThirdPersonCharacter.

Its a TopDown template.

Im trying to possess a thirdperson character in a topdown template

but not even the click is working in the the thirdpersoncharacter only in the topdowncharacter it prints.

and im doing exactly the same so i dont know

[twilit heath]

your collisions are likely fucked then

[trim matrix]

Check the collision settings on the ThirdPersonCharacters CapsuleComponet

Im pretty sure, by defualt, it ignores the visability trace channel

And by default, the click events, use the visailibty channel for its linetrace.

Make sure the capsule componet blocks visability channel

[cyan bone]

It is exactly the same as the TopDownCharacter that is working. Its a pawn collision.

How can i diagnose why its not working?

[trim matrix]

You may be clicking another part of the TopDownCharacter that does in fact block the visability channel.

Try setting the collision preset to custom, then set the visability trace response to Block

[cyan bone]

you are a legend. that worked.

thank you

i just wanted to know why is this not needed in the TopDownCharacter, but it is needed in the ThirdPersonCharacter, if both have the same settings

[trim matrix]

On your TopDownCharacter, there is another componet that you are able to click on

Some other componet in it blocks visability im sure.

[blissful grail]

Currently have an actor swinging on a pendulum-like thing. The actor is attached to the pendulum bob, after a full swing, the actor detaches from the bob. How can I preserve the momentum of the actor? When I detach, it does a small jump to the side (like it unhooks from the bob) or throws the actor straight to the ground, even though it should be sending it higher.

[devout geyser]

try to get the velocity in the vector rotation and re-apply that force? with apply force node? maybe 😄 I am not certain about it

[high fractal]

Isn't this just a physics issue?

Do you want your "release" to be realistic, or accurately controlled?

[blissful grail]

Realistic.

[blissful grail]

I've tried that. Was one of my first ideas 😅

[high fractal]

What you can do is simulate physics.

[devout geyser]

umm maybe watch a grapple hook tutorial it will give you the idea of how to revolve your code around the grapple physics?

[blissful grail]

None of them work at low FPS.

They all follow the same logic. But if the game has low FPS, it completely breaks.

I went through at least 6 researching my issue.

[devout geyser]

so is the issue with the fps or with the code? i am not following

[blissful grail]

When I tried that - the actor wouldn't stay attached to the body.

[devout geyser]

you can attach a physics actor with physics handle

[blissful grail]

The issue with your 2nd suggestion is that the code in the tutorials doesn't work at low FPS. The reason I know is because I already tried it.

I have tried my approach, tried the tutorial approach, and now I'm doing a physics constraint approach. Thus far, the physics constraint approach has given me the best results.

[devout geyser]

This is the result: https://streamable.com/743vxz with using physics handle,

when i release the battery it launches as the direction and with the force it has applied

like this ^

if that's what you need i think ^_^

[blissful grail]

Looks promising. Does that go on the actor that is swinging?

[devout geyser]

what? 😄

[blissful grail]

Right now, I have a semi-jank way of doing it 😅.

[devout geyser]

no no

[blissful grail]

The physics handle.

[devout geyser]

its not complicated at all

like literally childs play

Equip your pshysics thing you want to launch with the physics handle and you will have functions to play with

This is the player's code looks like

Pretty simple to understand @blissful grail

[blissful grail]

Yeah - it's more of a matter of getting it integrated with my setup. That's all.

[devout geyser]

Alright, good luck! I am not much of physics expert just sharing me experience for the hope it will help ya!

[blissful grail]

I'm doin' a side scroller, so I need to get it working with the character swinging on the grapple point and what not.

[junior hedge]

How can I clone an object when doing something (Pressing a button), and it will clone that object while the game is running

[broken wadi]

Make a custom event that sets a variable using your object and assign it to an input key?

or are you speaking of some kind of actor in your level? Ex: Character walks up to button, presses it, and now there's another box in the room.

[junior hedge]

that

[broken wadi]

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/SpawnAndDestroyActors/#:~:text=Input Action Event.-,Drag off the Pressed execution pin and from the Executable,select Bp Actor to Spawn.

[junior hedge]

i sighed but i didnt know the ue docs were this good

is there an updated docs version for ue5 though?

[broken wadi]

its the same blueprint code

[junior hedge]

alright

is there a way to import binds to another project?

[desert juniper]

inputs?

if so DefaultInput.ini

[junior hedge]

where is that located

[devout geyser]

Ai resisting a task 😛 I made an AI but it doesn't go along with the behavior tree any suggestions?

[junior hedge]

bindings

[desert juniper]

yes input bindings. theres like 20 other things that can be bound, so being specific helps

gameroot>Config>DefaultInput.ini

[junior hedge]

right

thanks

[desert juniper]

👍

[junior hedge]

is there an unreal doc for clamping the Z camera rotation? I cannot find one

[maiden wadi]

In regards to what? Clamping Z rotation is rare. Pitch is usually a more common clamp.

[junior hedge]

I want to make it so you cannot look behind you

So you can only look left in right

For example like you're sitting in a room

[maiden wadi]

Few different ways. Not sure if there are tutorials on it. Doesn't sound very flashy enough for a youtuber to get viewers.

PlayerCameraManager has a min/max yaw. Possibly could be used, but requires some world conversion math. Possibly less scalable.

More appropriate might be the spring arm/camera. The actor that is taking inputs can be ticked to force the camera's rotation or the player's Controller's ControlRotation to a certain point.

[near wolf]

Hello, I was following a tutorial for free camera look, it works, but these rotator nodes left unpinned because I had them before that and they were not in the tutorial. What are they for and do I need to connect them somehow to the rest ?

[rapid robin]

[UE5] [Screenshots].

EDIT: Fixed! Seems my file names were getting too long, colons and file names don't mix well...

Hi all, I'm writing a script to take a bunch of screenshots. All was cool until it stopped working. When I run the map it still tells me it's taking the screenshots, and it reckons it's saving them in the correct place, except the folder is empty. I no longer get the pop up linking me to the folder.

Folder location is: [game]\Saved\Screenshots\WindowsEditor

The weird thing is that it was working fine previously, and it stopped working without me changing anything.

I do however have one raging clue: When I look at the folder itself in Windows, it seems to be set to Read-only. Even when I untick it, and then check details again it seems to like setting itself back.

Anyone any ideas on this one?

[junior hedge]

Anywhere I can read up on the PlayerCameraManager min/max yaw?

[grim peak]

I have a question. I currently have a Screen_BP which triggers the Thirdperson character and draws the widget on screen when E key is pressed. In the Screen_Widget I have Image array that contains my images. If I wanted to have slideshow and have it to goto next image with some delay 4 secs. Do you inplement this in the Screen_Widget? My question what do I need to add to do this anyone 🙂 ... is that Integer + and delay. Can anyone show me how to do this? Is it difficult to setup?I couldn't find much info on I-net aboyt slideshow stuff. Thanks

[cursive ermine]

If you wonna do a Slide show then I would suggest doing it the Screen Widget. You can add a Picture and Change the Texture (the Picture Content) in BP over Time depending on the selected Index in your Array. Its pretty easy to do. Just some Index Addition, a Delay and Replacement / Change Texture Node

[worthy tendon]

I would put ImageIndex variable inside the Screen_Widget blueprint directly.

and you can control the slide show with a delay node, increment index, if index reaches array length then reset index to 0.

actually a timer would be better than delay node

so you can dispose of it

[grim peak]

Thank you both. So i need to make a new var. called Imageindex in the screenwidget_BP. How do you increment index Integer+ and reset index to 0. Is that like loop node? and use some Timer node?

[worthy tendon]

all of this should be inside Screen_Widget

call StartSlideShow to.. well... start it 😄

call EndSlideShow before calling RemoveFromParent

[neat lava]

Anyone i need help I have a Child Actor Attached to CharacterMesh the child Actor Class is BP_Sword ,In another blueprint i have a reference to the CharacterMesh how do i get the Child Actor and cast to BP_Sword

please help

[worthy tendon]

(index + 1) % length will become 0 when index+1 reaches length.

[worthy tendon]

what is the name of child actor component in your CharacterMesh?

[grim peak]

Cool.. thanks so much I will give it go.

[neat lava]

Child Actor

[worthy tendon]

cast to your type

[neat lava]

i will try it

[worthy tendon]

GetChildComponent is wrong

[neat lava]

ohh

so what should i use

[worthy tendon]

just get ChildActor (this is the component) and from that get ChildActor again (this is the actual child actor)

[neat lava]

i dont get it

[worthy tendon]

something like this

[worthy tendon]

here, from MeshComp, get child actor twice like the image i gave to you

then cast it to sword.

[neat lava]

okok

[worthy tendon]

note that when you type get ChildActor it appears at very bottom of the search (so you should scroll way down to see it)

[devout dove]

Hello everyone, when creating a character, where do I put the whole "health" and "mana" part? Into the character itself or some game state or struct or player controller? The character will die but I will just "respawn" it after clicking a button instead of "destroying" the character.

[cursive ermine]

I would do it in the Player Character. Cause this is the one who has to handle all that (e.g Check Health -> if =0 -> death Anim). If you do it in a Controller all the Health and Mana will be dealt there and this doesnt make much sense casting from the Charcter to the Controller (or the other way around) just to get the current Health and Mana.

[neat lava]

@worthy tendon is this what u mean, anyone is this ok to cast to 2 time

[uneven geode]

does somebody work with simpleUGC here?im loosing my mind

[worthy tendon]

woops, didn't notice MeshComp is a component. yeah this should work, it should be ok since it doesn't happen every frame (even if it does, two casts per frame is nothing)

[neat lava]

ya its is working thanks

[grim peak]

I'm looking into it.. That Slidershow Timer Handle.... what's that for node. Is that var? thanks

[worthy tendon]

drag from ReturnValue of timer, and promote to variable. handle is used to later destroy the timer.

[hallow compass]

Hi all, a lot of my blueprint logic seems to be broken when updating from 4.27 to 5. No errors or anything like that, but a lot of the code just isnt working as it should - character references, animations playing when they shouldnt , widgets not updating, it's a mess. Has anyone had similar issues or know what it may be? Maybe some visual studio related problem? Any help would be much appreciated!

[neat lava]

@worthy tendon how do u get the Owner of the Child Actor Component

[devout dove]

Ok thanks for the help 🙂

[worthy tendon]

GetOwner should work, just like what you did with MeshComp. but by Owner im assuming you mean the actor that has that child actor component.

to get the actor inside child actor component, then just ChildActor.

[neat lava]

no the BP_PlayerChar

[neat lava]

when i do that it return NULL

[worthy tendon]

hmmm

[neat lava]

ya

[worthy tendon]

did the cast run successfully?

[neat lava]

yes it did

otherwise get the faild message

[worthy tendon]

you can also try this instead of get owner, but wait

[neat lava]

ohh nice

[worthy tendon]

it should be from this node instead

[grim peak]

Hi, does this look right? its not going to next image when I press E key, maybe I need to add some stuff here too? or is one of the vars set incorrect?

[jolly cairn]

hi, any reason why the component doesn't get created and added?

the exec pin after fires off, no errors or anything. just no component is created

[worthy tendon]

did you call Start Slide Show?

[worthy tendon]

right, but you should call StartSlideShow from Screen_BP after AddToViewport.

[jolly cairn]

my aim is to have the component pop up here so i can use it later on

[worthy tendon]

drag from return value of Create Screen_Widget node and call StartSlideShow, put it next to AddViewPort.

[worthy tendon]

component is added but unfortunately, it wont show up in there.

[jolly cairn]

ah, i need to be able to see if it's adding the correct data to the component when it's added. How can I do that?

[sinful gust]

My Unreal is drunk again, why do I have the exact same variable repeated 3 times and, when I delete one of them, my whole code collapses? lmao

[jolly cairn]

basically it gives it the data from my data table i'm already fetching

[worthy tendon]

the only way would be to add variables in your actor, and copy them in your newly created component.

oh, if you just want to be able to see variables, then copy them from the component to your actor,

[worthy tendon]

is this inside your component?

[jolly cairn]

the fetching of the data? no, that's handle by my actor

i have an actor called TaskManager, that is responsible for randomly choosing the tasks the player has to do

[worthy tendon]

what does the component do?

[jolly cairn]

the component is each task

just has functions/variables like is it completed, how many ticks have been done, etc

[worthy tendon]

first, I would suggest you to pack these variables inside an struct.

then in order to see them from actor details panel, create an array of this struct, then fill that array with your tasks. you should be able to see them then

[jolly cairn]

i will have functions on these components though, will structs allow that?

(im new so dumb question)

[worthy tendon]

your question is fine 😄

ok, if you dont want to ruin your existing blueprint, make this struct for debugging purposes only. so this struct is only for you to be able to see what tasks are there. but components do the stuff as they are doing it already

kind of like a debug view

[worthy tendon]

have an array of struct, lets call it CurrentTasks.
then add a timer in actor that runs every 0.1 second for example

on that timer, clear CurrentTasks.
then get task components, for each component make an struct and copy all info from task component in to that struct. add that struct to CurrentTasks.

make sure CurrentTasks is instance editable so you can see it in details panel.
again, this variable is only for seeing tasks, nothing else.

[jolly cairn]

thanks! will give it a try 🙂

[grim peak]

Still trying to figure things out... you mean like this?

[worthy tendon]

since its editor only, i would suggest you to mark CurrentTasks as transient as well.

[still rain]

Is this possible to “bend” decal to spline shape? I know it is possible to bend static mesh like this, but I did not found a way to do the same thing with decals.

[worthy tendon]

oh no

[worthy tendon]

this was fine

go to Screen_BP

@grim peak like this 😄

[grim peak]

like this?

[worthy tendon]

yup, this should work now, does it work?

[worthy tendon]

woops, missed that. in this image, you are getting ImageIndex from player character, dont do that, use the ImageIndex inside Screen_Widget

[worthy tendon]

also here, you are setting Image integer to ImageIndex in player character. you should set that to Screen_Widget instead.

and remove ImageIndex from player character. since it's in Screen_Widget.

[prisma tree]

what is the best system to use when controlling cameras in unreal 5?
....sequencer?

[spark robin]

How do I even know where something like this is coming from?

A pawn obviously, but which pawn?

Is there no traceback?

[spark steppe]

that depends on what you want to "control"

you can also make cameras follow a path, without a sequence iirc

[spark steppe]

i would search the specific node (enableInput or whatever) in all blueprints and add debugging/breakpoints if you can't figure it out another way

[jolly cairn]

how can i get a reference to the my widget for the HUD that's added to viewport from another blueprint?

[unique turret]

This was from last night, but to continue: I'm using a ChildActorComponent as a door with all the animation and variables, but then BPs to setup 20+ variations of the door with different meshes (different frames, basically). What would be an alternative to ChildActor Component setup for a case like this, where I may still want to tweak door animations etc, but don't want to have to make that change across a bunch of BPs.

This is the simple construction script I'm trying to send to the door. "Door locked" boolean seems to be set fine, but for some reason the Door window isn't getting set.

The "door window toggle" is being used in the ChildActor's construction script, am I correct in guessing this is the issue? The order in what the construction scripts are firing? A way around this if that's the case?

[tawdry surge]

Yeah, don't use child actor components
They randomly fail, lose references, and suck in general

@jolly cairn where did you make it and add it to the viewport from?

[unique turret]

Yeah, I'm seeing that, haha! Is there an alternative, though? It's nice to have the functionality propagate across the board. I can rebuild all the doors with no childactors, but then any minor adjustments that need making have to done 20+ times.

[jolly cairn]

level blueprint because this only comes up on certain levels

i managed to get a reference to the HUD variable using a cast, but it's saying it's referencing none, when it's definitely being set

[tawdry surge]

You can't access the level BP from outside.
You can make an event dispatcher and have the level BP listen for the call and then have the level send the reference wherever you need it.
But
Id probably put it in the player controller or pawn class tho and just turn it on as needed

[icy dragon]

Or not using level BP at all

[tawdry surge]

@unique turret I'd make a component for the movement logic and use an few exposed variables on the construction script to handle my different variations

[jolly cairn]

it's being set on the character by the level

[tawdry surge]

Right.
Just move that to the character and make it from there.
Much easier to access, and if you really want you can throw a bool on it (in the character) and have the level decide if it should be on screen or not

[jolly cairn]

tried that, still getting accessing none error

if i view the character in the inspector during debug, it's getting set

[tawdry surge]

You made it on the character, saved the reference, but when you get the player character, cast to your class, and get the ref it's empty?

[jolly cairn]

right, i put it on the player, the variable holding the HUD is set. It was doing this both on the ways (on character, on level BP). I have an actor called TaskManager that needs to call a function on the HUD that's created and put those tasks on the screen

even when the HUD is set, it's saying Accessing None

[tawdry surge]

Lemme see the player and task manager code then.
Cuz if the character is creating the widget-> promoting to a variable
And task manager is getting player character-> casting to your character class-> getting widget ref, then it shouldn't be null

[jolly cairn]

this is the task manager, im in the middle of trying to work it out myself through trial and error at the moment so bits are probably missing

and i deleted the functions i made to start over, so got none now on the player

but this is on the player, creating the HUD and storing it

but for the sake of showing code.. this is the a function that would be called by the task manager. this lives on the player

and at the moment, i created one for the HUD to literally print something to test

So

Task Manager -> Player -> HUD

[tawdry surge]

Ok.
I don't see a "debug hud" variable in the task manager or where you're calling "show tasks"

[jolly cairn]

ye because you asked for code and i dropped everything to get a screen shot

[tawdry surge]

Haha well if you don't have those two things how is the variable supposed to be passed around

[jolly cairn]

on task manager, this is essentially what i want to happen

task manager won't want to know the whole HUD

[jolly cairn]

goes to

[tawdry surge]

Ok, so you're just calling a function on the player and letting them deal with the hud

[jolly cairn]

yes

[jolly cairn]

this goes to this

[jolly cairn]

i've decided that's the best way to approach this as i'm then not exposing the entire hud to the task manager just do one thing

Blueprint Runtime Error: "Accessed None trying to read property DebugHUD". Node: Show Tasks Graph: ShowTasks Function: Show Tasks Blueprint: BP_FirstPersonCharacter

ok for some reason it's just not getting set at all

[tawdry surge]

Yeah that's weird. Looks like it should work.
You can try deleting the variable, restart the editor, and see if it was just being dumb

Occasionally that works

[jolly cairn]

even with restart, not working...

hmm

[white elbow]

my float tracks seem to have just erased themselves, anything like that happened to anyone?

[naive stag]

How can I make a macro that will check if a number is even and then have an output of a Boolean

[vast horizon]

Does anyone have any advice/resources they know of for dealing with a game having over a 1000 AI controlled characters active?
I'm working on an RTS with a 3v3 max player cap, with an in game cap of about 1500 units total. It's entirely possible for the game to have at least 1000 units on screen at a time, each interacting with each other. So they can't really be set to 'sleep'.
I have a pretty strong system but it crawled to 8fps when looking at all those units stationary on screen, and when I issued an order to about 200 of them it crashed hard, said it hit an infinite loop within the 'assign to index' function within Unreal.
The hitch is it isn't something I can just simulate with particles for example, each of the 1500 units is an individual controllable character.
Any help / resources you know of for this would be great.

[jolly cairn]

even with a new variable, pc restart, it's just refusing to set it now

[indigo bough]

I have "Run Construction Script on Drag" disabled, but when moving the vector variable's 3D widgets, the blueprint still runs the construction script. Is there any way to avoid this?

[candid geyser]

Okay, so I have things going. Anyone have suggestions for when moving a component from point A to B, how could I prevent it from going through any objects it collides with?

I know I would need a way to detect the collision, and then make it NOT touch it haha but im not sure what an effective way to go about that is

[candid geyser]

Not like an actual object, it's just a cube right now that I want it to not go through

Alternatively I could just make it go straight up and then over a bit

[worthy tendon]

are you on ue5?

[naive stag]

Please help

[worthy tendon]

use Mass plugin, go with ECS instead of OOP

but it has to be in c++

https://www.youtube.com/watch?v=f9q8A-9DvPo

[vast horizon]

That's the issue I have absolutely no experience with C++ at all, or programming outside of blueprints.

[worthy tendon]

unfortunately, for that amount of actors, blueprint is just not good enough.

blueprint can be used, but core of the simulation must be in c++.

[vast horizon]

Ah, damn that sucks for me!
Perhaps they can bridge them later in the future.

[worthy tendon]

== 0 not 1

[zealous moth]

this is a particular challenge even to me. What you would need to do is a series of traces and behaviours hardcoded in to avoid obstacles

I recently purchased an asset called "Monsters bundle" that claimed to do that but it is exceedingly buggy and asked for a refund

the idea is good but the implementation was crud

[tawdry surge]

@naive stag modulo
if the return is 0 it's even

[worthy tendon]

not sure how long it takes for them to do this, but it has to be some kind of nativization algorithm on your blueprints to make it efficient. otherwise it just defeats the efficiency of ECS. (you want to avoid cache misses)

[manic geode]

erm... Did they change the Static Mesh icon in UE5?

[candid geyser]

I see. It might just be better if I do the component movement in such a way where the player wont clip inside. Or at least the camera wont.

[zealous moth]

it's a difficult thing since there is no out of the box support

I've been trying to make wall crawling AI or pseudo AI for months and almost all attempts are fudged

[candid geyser]

Oh jeez, sounds rough..

[candid geyser]

Definitely, only issue is that I dont know how to set the target destination for a move component node in such a way where it knows where it needs to go, but only moves along the Z axis instead of all of them

Actually, I have an idea

[strange stream]

I have an array with a bunch on integers - and a random integer.
I need to check what integer in the array is closest to the random one and set it.
How would I go about that?

[candid geyser]

That immediately did not work haha

[zealous moth]

only Z?

[zealous moth]

do a for each, get the difference and whichever has the lowest difference is closest

[candid geyser]

WAS ABOUT TO SAY THAT HAHAHA

WOOO IM SMART

[zealous moth]

S M R T

[candid geyser]

Yeah.

[zealous moth]

why only Z?

[candid geyser]

SHHH

[strange stream]

Kay i'm stupid, how do I get to the difference?

[zealous moth]

Int - RandomInt

[candid geyser]

Because in order to avoid clipping into the collision, it needs to still know exactly where the destination is, but only move along the Z a certain distance so that it will avoid going inside the geometry

Or move up slightly offset from the end point

[worthy tendon]

that's an ugly looking brick 😄

[manic geode]

where is the house

[hybrid horizon]

A simple temporary fix could be to add a instance editable boolean with a branch on construction that you can toggle off before moving then back on after moving

[manic geode]

is that correct icon?

[calm light]

Hi, I had this issue yesterday to trigger an event track from sequencer. Now everything should be set up correctly but render stops at the event frame and open the blueprint, looking like on the screenshot. I am missing something, again, right ?

[icy dragon]

Disable/remove the breakpoint.

[calm light]

you mean by doing f9 on the red node ?

it does not trigger any action if I remove the breakpoint

[icy dragon]

Well, typically you want to breakpoint something after an event...

[calm light]

I don't know yet how blueprint works, sadly and ue documentation, I don't understand solution for my case

I only need to trigger this single action multiple times

[zealous moth]

the break point there is used for debugging. If you dont want it to pop up like this, right click the node and at the bottom it says "disable breakpoint"

[calm light]

I thought it was used to trigger the action 🙄 thanks !

[zealous moth]

np, breakpoints can be very useful to follow around logic and see what happens to values

[calm light]

I'll look for more on youtube to see if I can understand the logic behind this 🙂

[subtle phoenix]

Every time I restart the editor, the Orientation Warping node gets deleted. Has anyone experience this?

[worthy tendon]

can you successfully save the asset?

[subtle phoenix]

yeah

[worthy tendon]

weird

[subtle phoenix]

i even saved and push to my github

made a copy after a saved, and its gone after restart

[worthy tendon]

try duplicating the asset and see what happens for the duplicate.

[subtle phoenix]

same thing

[worthy tendon]

oh

[subtle phoenix]

all the dupes get deleted

[worthy tendon]

what if you make a new one by hand? dont over do it, just make a new blueprint and throw this node in there and see if it saves or not

[subtle phoenix]

i check the .uproject and the Animation Warping plugin is enabled.

ill try that

hmm, didnt get removed in a new anim blue print

[worthy tendon]

now comes the hard part

over do it? 😦

[subtle phoenix]

ill keep adding one thing at a time and restart

until it happens

[worthy tendon]

is your project C++?

[subtle phoenix]

yeah

[worthy tendon]

did you use hot reload?

that can mess things up

[subtle phoenix]

i did a clean recompile

still happened

[worthy tendon]

it doesn't matter, if you save a hot reloaded blueprint, chances are it becomes corrupted and only way to fix it is to make a new blueprint and redo all the work. I hope you didn't do that

it happened to me before so i stopped hot reloading for ever

[subtle phoenix]

its Unreal 5. i've been using Live Coding

yeah hot reload has corrupted my blueprints before

[worthy tendon]

yeah, i don't know about that once, they say it's good and wont corrupt stuff but i haven't tried it for my self

[subtle phoenix]

i use it because hot reload has gave me a lot head aches

[worthy tendon]

I would duplicate graph by graph, that would be faster but tedious nevertheless.

[subtle phoenix]

yeah i could. but i made most of my functions in c++. just matter of calling them again

[worthy tendon]

that's nice

[subtle phoenix]

damn it disappeared again lol

[calm light]

Thanks @icy dragon and @zealous moth now the event works. It was only spawn location issue, reason why I didn't see it during render

[worthy tendon]

its probably the nodes that you duplicated? so maybe just redo it without duplicating. then there should be no way for corrupted things to leak into new blueprint

[subtle phoenix]

im not duping anything.

just straight remaking from scatch

[worthy tendon]

it's just weird for a node to disappear. never had that issue lol

try collapsing the node, maybe it prevents it !

[subtle phoenix]

yeah well ill keep messing with it later. gotta log into my work computer and do boring programming

thanks for the help

[icy dragon]

Breakpoints are essentially just a way to pause a running program, to see if part of a code is executed or not. It's mainly for debugging purposes.

[misty pendant]

Hello, any idea how i can make the script when im unhovering to actually work? Please can someone explain how to make it work i've tried to fix it myself and didnt understand im kind of dumb

[old swift]

ok I'm really f'n confused here... are character physics assets only intended for ragdoll simulation or what? Like, I want colliders attached to bones, but I don't want the colliders to act as individual physics bodies that influence the skeleton/animation. I'm not seeing a way to make that happen...

[open wren]

hey guys, for some reason if i use chromatic aberration in my post process volume it doesn’t seem to change anything… Any ideas why?

[spark steppe]

set the bodies to kinematic in the physics asset

instead of default/simulated

[old swift]

but then my character has no physics simulated...

I guess I'm meant to have a separate component for the character motion, and the "physics asset" is just for flourishing?

[limber lake]

quick question how do you measure the distance between two objects? I want to find the distance between the side of my car to the wall so I can use it for its Ai

i have googled some solutions online but they only give the distance to the center of the object

i would like it to work more like a sensor

[faint pasture]

What exactly are you trying to do?

[old swift]

I just want collision on my character that roughly matches the skeletal mesh

[naive stag]

How can I make lots of actors rotate 90 degrees horizontally

[faint pasture]

Are you using the typical Character setup? Like the Unreal Character?

[old swift]

no I have a custom setup that uses raycasts for ground interaction, so no typical large capsule collider

[faint pasture]

Then that's on you to handle collisions between the skeletal mesh and world.

ACharacter uses the capsule, you want to use the skelmesh simple collision, right?

[faint pasture]

At runtime or in the editor?

[naive stag]

Runtime

[faint pasture]

Get actors -> for each actor -> add rotation

[naive stag]

No, I want all actors to rotate 90 but still have their own positions

[faint pasture]

That's exactly what I told you. Have you tried it?

[naive stag]

Ye. I just need to rotate those actos as if they are the same object

Instead of rotating all of them separately

[faint pasture]

@naive stagAre you trying to rotate each one 90 degrees without moving, or grab them all, and rotate the entire set 90 degrees (moving them)?

[old swift]

I'm not inheriting ACharacter, I'm inheriting AActor. I'm not sure what you mean by "skelmesh simple collision", but I imagined I'd have a single rigidbody being simulated with its colliders being defined by the character's physics asset, if that makes sense...

[tight schooner]

Good question... Might have to do line traces? There is this node but only works on simple collision https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Collision/GetClosestPointonCollision/

[naive stag]

Second one

[faint pasture]

There's a way to simulate physics on a skelmesh but still have animation drive it. Don't recall the specifics but dig around, it's in there

You'd end up with a QWOP-like experience

The physics asset IS your set of colliders. Don't add more colliders to the skelmesh.

[old swift]

Yeah that's what I figured, but the issue is they act independently and override the animation. I've been digging pretty hard, but hopefully you're right and there is a way. Like, what if I was trying to make QWOP in unreal? I would hope that would be possible in the given framework...

Anyway I'll probably soon give up on quality and just do the standard unreal canonical character controller...

[faint pasture]

There's a way to do it, I've done it. Don't recall the specifics though

Something to do with simulating physics on the pelvis only

or whatever the rootest of your colliders is

[old swift]

thanks

[covert stirrup]

How would I go about casting a line trace to a specific component hit to make it trigger a custom event related to that component?

[faint pasture]

Whoah whoah slow down.
Is this a 2 parter?

1. Line trace towards some component
2. If it hits the component, do something
   ?

[covert stirrup]

Ok so, I have a BP with 3 widgets in it, I am using a line trace to detect which widget is hit; Upon hit of widget 'A', I want to hide widgets B & C.

[faint pasture]

Do you have the first part done? Are you able to detect a hit?

[covert stirrup]

Yea so I have the LT; I am unsure as to how to use the hit component to do as I need it to do

[faint pasture]

Do you have 3 widget components or one with 3 child widgets inside of it?

[covert stirrup]

This is the current setup

So 3 components

[faint pasture]

@covert stirrupThat looks like it can get real fucky real quick. What are you trying to do? Looks like some sort of a pick one of three choice type thing?

[covert stirrup]

just trying to make a 3d menu system

If A selected, hide B&C and show D

UI is a bit weird in UE

Will have to do it as seperate actors I guess!

[lost heart]

is there a good low-level description of how blueprint works? I thought I mostly understood it, but...

I have a for-loop that calls an event with the current loop value and inside the event, I execute a print on one of the input pin arguments (I get the correct value here), then execute a delayed action which execute print on the same input for the first print and here I incorrectly get the value from the last event invocation for all calls to the event.

I would have expected that to be equivalent to either a function parameter with the value stored on the stack or possibly captured by-value in a lambda, but apparently my intuition is wrong here. Is there an easy way to capture the value of the event argument here (so that its distinct per invocation after the event)? I tried making the event call a function, but realized I can't actually put a delayed action into a blueprint function body

[faint pasture]

No you don't

Do you always have 3 choices? or is it dynamic (1-X number of choices)

[faint pasture]

The for loop body will fire all the times in sequence, then later, the delay fires once.

[lost heart]

no the delay is firing for each call

its not a delay node exactly but something that extends UBlueprintAsyncActionBase

[faint pasture]

You're telling me the output of that delay fires X number of times, not once?

What node is it exactly

[covert stirrup]

Currently only the 3 options; a work around I have found is making BP actors that contain each seperate widget and spawning that inside the. Original BP with the widgets in. That way I can get a specific actor hit and do what I need

[lost heart]

its a custom node that downloads a file and then calls an execution pin with the results. I call this every time the event is fired. on the afterdownload execution pin attached to this node, I print the length of the result concatenated with a string passed to the event. This string unexpectedly gives the value from the last call to the custom event instead of the current invocation, although the length for each invocation is correct (and different). I want to know how to properly "capture" the arguments for each invocation so I can use this in a for loop (without passing every possible argument to the execution node since I don't want the download node to need to know anything about other than how to download a file and call something with the results

[faint pasture]

You can get the hit component too, just gotta keep in mind what's elegent. Also, UMG has a bunch of click/hover handling stuff built in.
Anyway, it'd look like this
Line Trace -> Cast HitActor to Your3DMenuActor -> Call SelectThisComponent(HitComponent) and Your3DMenuActor handles it from there

Inside Your3DMenuActor
SelectThisComponent(HitComponent) -> ForEachWidgetComponent -> if not equal to HitComponent, hide it

Something like that

that's dirty and messy tho but it'll get you going.

You'd probably want an interaction or selection interface, where you can just
Line Trace -> HitActor.SelectionInterfaceCall(HitComponent)

and the HitActor handles it from there.

[faint pasture]

Show the CPP for that node

[maiden wadi]

Chances are that it just doesn't pull data until it's ready to execute maybe. At which point the for loop is done.

[lost heart]

I don't think I can share the C++, but
we're doing something similar to https://www.tomlooman.com/unreal-engine-async-blueprint-http-json/

The possibly relevant C++ parts are that it extends UBlueprintAsyncActionBase and Activate() calls

HttpRequest->OnProcessRequestComplete().BindLambda

and that lambda calls broadcast on an event declared via

DECLARE_DYNAMIC_MULTICAST_DELEGATE_TwoParams

(which is the afterdownload execution pin)

The print node grabs the string part directly from the custom event pin, not the C++ download node

[covert stirrup]

@faint pasture problem is I can't cast a hit component to my widget actor to get a detailed idea of what was hit specifically; if I make it actors within my main BP instead of components, I can seperate them as individual hits

[faint pasture]

The hit returns the actor AND the component

Tell the actor "Select this component" and let the actor handle it from there

Cast the actor to YourMenuActor (or use an interface, much better idea, or even handle selection on the UMG widget level)

[covert stirrup]

hmm, it wasn't working for me; any sort of casting option was giving errors, got example BP code?

[faint pasture]

Do you know what casting is?

It's not the magic word to make things just work.

[maiden wadi]

Can you show your BP setup relevant to the loop?

[covert stirrup]

@faint pasture I am aware of what casting is but components have been causing me an issue with making them work as intended

[faint pasture]

Try implementing what I laid out

Get the hit actor -> cast it to your menu actor (to make sure you aren't hitting a door or tree or wall), call SelectThisComponent(HitComponent)

Then in Menu actor

Event SelectThisComponent -> hide all components that aren't HitComponent

[covert stirrup]

Where are you getting SelectThisComponent from? Are you referring to the break hit result 'Hit actor'?

[faint pasture]

When you break the hit result you can get the hit actor AND the hit component

SelectThisComponent will be a custom event you make on your 3d menu actor

widget componets might have some selection stuff built in already, that's worth checking out, but I'd do it this way first

[covert stirrup]

Maybe we are describing the same thing? my current working version was to call a custom event "selection 01" like this :
Are you describing something different

[faint pasture]

pass HitComponent as a PARAMETER in your selection event

so you can tell it what component you want to select

also I would remove that branch where you check its name

[covert stirrup]

currently it only works because of the branch in this format

I am unsure of your method :3

[faint pasture]

add a parameter to your selection event

[covert stirrup]

yes but replace it with what, you say a parameter but currently it's a string parameter so which parameter are you referring to changing it to?

[faint pasture]

oh god damnit, you have no paramters on that event right now

show your selection event

the event you call when you want to select a component inside that 3d menu actor

[covert stirrup]

right ok, you want to add a parameter to the event, I get you

wasn't making sense the first time round

[faint pasture]

Then in the 3d menu actor
SelectionEvent -> Get components by class(widgetcomponent) -> if not equal to parameter (the selected widget component) -> hide

that'll hide every widget component that is NOT the one passed into the event

[covert stirrup]

@faint pasture is this the setup you are envisioning?

[lost heart]

This isn't the actual blueprint but it should be similar although it can't be executed since there isn't a good builtin node that is similar to the download node
(Edit: corrected comment on 2nd print)

[tawdry surge]

I think those would be inputs or arguments. Afaik parameters technically refers specifically the function's local variables
But yeah that's what he prescribed

[faint pasture]

yep

[faint pasture]

Yeah events get weird. By the time you get to AfterDownload, that event pin will probably have the value last given to it.

[lost heart]

Is there a way to wrap a delgate in blueprint?
something like
//Javascript
function adaptor(bindArg2, twoArgDelegate)
{
return (arg1)=>{
return twoArgDelegate(arg1, bindArg2);
};
}
and pass the result of adaptor as a oneArg delegate?

[desert juniper]

you can definitely wrap a delegate call with a function or another event

though delegates don't return anything, so not quite sure what you're trying to do

[lost heart]

it looks like in C++ I can do it with
MyDelegate.BindRaw( &MyFunction, true, 20 );
https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/ProgrammingWithCPP/UnrealArchitecture/Delegates/

but I can't seem to do it directly in blueprint

[desert juniper]

can you explain what you're actually trying to do?

[lost heart]

basically I want to capture values ahead of something that happens asynchronously and then when the async task completes, receive a call with the results plus those pre-bound values. its the same problem as above, but I'm approaching it from a new method

[desert juniper]

Ah okay. I don't know if there's a way to perform a callback with delegates. Okay maybe someone else can chime in

[manic knot]

Is it possible to make Text still Bindable in a User Widget that is a child of text widget? Perhaps a dispatcher?

[misty kindle]

I have a door blueprint that has an object set to it as the key. Everything works fine but if I save and load the key variable gets set to blank. I tried on event begin play doing a get all actors of class and reset the variable to the object. Doesnt work. I tried deleting the first key and respawning the key and setting the variable. It keeps the first key and spawns a second key setting the second key as the variable. I am not near my pc right now but anyone have any ideas would be much appreciated.

[lusty arrow]

Anyone know how to make a light blind a player when looking into it? The light doesnt reflect on their screen for some reason

[manic knot]

Use a Trace from the light source to activate a Post Process?

[lusty arrow]

Ok, not a bad idea. What settings would you change on the post prcoess? I haven't really messed with that before

[manic knot]

Probably Exposure, White Balance, and Bloom if its enabled

[lusty arrow]

Ok, ty

[echo mist]

I should be able to also use this in networking game, right? Index 0 should alway be owning client if I understand the description correctly.

[shell echo]

Is there a way to store a delegate in blueprints?

[manic knot]

is it in a Widget or regular BP?

[echo mist]

Regular BP, parent class is Character

[maiden wadi]

Generally if it's in a character, you can get that pawn's controller and cast it to player controller. GetPlayerController can fail at times, specially on listenservers that servertravel. Certain cases lead to the client ending up with a controller before the server. Which leads to index 0 being a client and not the local listenserver's controller.

[lavish sphinx]

What does SKM_Manny_Invis do?

[faint pasture]

Bloom and exposure can do the work for you but it'll all depend on what you mean by "blind" and how your lighting is being done

If you mean a realistic blinding then you'll want to have a lot of slow eye adaptation going on (so the light just overwhelms it)

[faint pasture]

I can't think of a single situation where you'd want or need to get a client or playerstate by index, can you?

[limber parcel]

uhh im having a little issue here

it keeps telling me its an infinite loop

even though its clearly checking a condition

basically it spawns a building and repeats until it spawned 10 of them

so where is the infinite loop???

it points me to this part when i click the error

but it makes no sense since this just sends him to a different behavior which is working fine on its own

on removing this node it sends me to a different part of code which makes even less sense

here is the other event im using in this, should be good, no?

[hybrid horizon]

I would guess that your first branch is giving a true and your spawn actor is coming up not valid.
That's where I would think the infinite loop could be coming from

[limber parcel]

i tried removing the repeater at the end with same result

it worked until i added the AI MoveTo

and if i remove it it works

but idk how this would cause an infinity loop

[hybrid horizon]

I was just about to ask what an AI move to does because I've never used one personally.

Is it a function you can open in BP or does it only open in c++?

I'd guess it's doing a loop itself and the condition for "on success" is probably not being met.

[limber parcel]

its a built in function

which tells AI controller to move to a vector or actor

[hybrid horizon]

Maybe it needs something plugged into target actor?

[limber parcel]

no it works with either destination or target actor

this fkin error makes no sense at all

basically AI doesnt even work if it wasnt an infinite loop

or should it just stop doing stuff at some point -.-

guess my fkin ai is simply not allowed to move to a location before placing a building 🤦‍♂️

adding a delay instead of the move to gives me the same error

[thin panther]

you call the function at the end of executing the same function

that will throw an infnite loop error

as it will try to execute this in one frame

[limber parcel]

no it will still do same shit if i remove the execute at the end

[thin panther]

whats in find buildable location

[thin panther]

this really sounds like something that could benefit from behaviour trees

[limber parcel]

here find buildable location

[thin panther]

behaviour trees would solve a lot of this

[limber parcel]

yeah but they are tedious to set up

so i just used this blueprint to get some basic stuff working

but i guess i wont get around using them anyways

i would still like to know whats the issue here though

am i missing something about how blueprints execute stuff?

[twin shale]

Anyone know why Get All Actors of Class returns 0 during play? There is only one actor of this class, in a streamed level. From what I can tell, this should be possible. This is called form the Pawn after being possessed

[tawdry surge]

Is the streamed level loaded?

[twin shale]

Yes, my character is literally standing inside it, and I can see the Actor

I just tried from the game mode...also returns 0

[tawdry surge]

Well you're right, it should work. I used that behavior extensively in a rail shooter I made
You sure it's the right class?

[twin shale]

I just triple checked that it was the same class just to be sure. I also placed a second one of the same class in the level, outside of the streaming level...still 0. I should be able to call Get All Actors of Class at any time, right?

[tawdry surge]

Yeah

[twin shale]

Welp...I fixed it. The constructor for the actor is firing after I possess the character. I moved the check to begin play and it works fine now. The more you know.

[tawdry surge]

Yeah. I usually let actors contact the persistent stuff like character, controller, game mode, game state, etc.. and essentially register itself.
Avoids those type issues

[twin shale]

That's honestly one of my largest weaknesses lol. I never know what spawns before what

[tawdry surge]

In general it goes instance, level, game mode, everything else

Controller is usually b4 the character in my experience, but idk if that's guaranteed

[maiden wadi]

Depends on the situation. Local Coop uses that system a lot. But even there I'm not sure if it's necessary given everything in widgets runs through their owning HUD and Controller. At least as far as UI there's no use for it. I don't know about coop gameplay.

[remote meteor]

is there a proper way to toggle ray tracing that is intended to be shipped with the game other than setting through console commands?

[tawdry surge]

Probably game user settings but idk for sure

[junior hedge]

okay so my first person character scripts work but I cannot spawn off them, idk why. I simply spawn wherever I am hovering

[desert juniper]

add player start actors to the level

[junior hedge]

Getting an error in a blueprint that says PreviousHealth of type Float (double-precision) doesn't match the property PreviousHealth of type FloatProperty after converting to UE5. Any fixes?

[round compass]

re-make the health system?

[trim matrix]

update your bind functions to use doubles by changing the types to floats again and refreshing nodes.

this might work

In UE5 most floats have been converted to doubles

[junior hedge]

how can I make the mouse cursor show when playing the game automatically? I have it so I need to press q and I don't think it would be smart to make a tick event to always show the mouse cursor if a variable is running (I cannot do BeginPlay because you need to first remove your mouse cursor when you tab in)

[trim matrix]

Show Mouse Cursor, Enable Click Events, and possibly Enable Mouse Over Events. in Player controller

[still trellis]

Yeah, literally just deleting all the nodes and then remaking them exactly the same fixed it... weird.

[trim matrix]

you have to set each pin to use float again, even if it already says it does. That’s essentially changing float support from ‘single-precision’ to ‘double-precision’.

[still trellis]

well the weird part is the nodes that weren't working were on a callback from a c++ delegate, that is just using "float"

[round compass]

Sorry if this isn't the idea solution but idk anything that would fix it more easy.

[junior hedge]

thanks

[trim matrix]

np

anyone knows if you can set character roles (for ingame character class Change) by making a child out of Player BP and then setting each Child as a class ?

[mental trellis]

Absolutely. That sounds like a fine idea.

[trim matrix]

i think ill stick GamePlay tags to each BP of Child then with that ill Restrict Inventory and Abilities and such

each BP will also have its own HUD

i think that will work right ?

https://www.youtube.com/watch?v=Ln7WBrv_lx8

[mental trellis]

Yup.

[trim matrix]

this person got the mesh to swap

when you press a button

[mental trellis]

You can just spawn an entirely new actor and possess it.

Don't screw about with mesh swaps.

[trim matrix]

Adventure is in the open world

but when going in Quests and such

[round compass]

Wait so how do i add custom InputActions ? Because i've seen there's jump inputaction but i want to make for crouch.

[trim matrix]

you switch to one of the Sub roles

[mental trellis]

Right.

[trim matrix]

check out #gameplay-ability-system its much better to add such there

[trim matrix]

each role has its own Quest's, Inventory, Ability and such

so its a bit complex

but i think best way is to use Gameplay Tags

[trim matrix]

Project Settings -> Engine -> Input

[round compass]

wasn't so hard. it was easy. just some little words like Rappy

Thanks.

[solar sequoia]

I don't necessarily get why you wouldn't just switch actors. You already mention needing some type of UI to make the transition, so just do it then

The hierarchy in the illustration is also a bit confusing. Why not just incorporate the leftmost column into the one with the classes?

The Complex part is that Each Role has its own Inventory, HUD, Leveling system, Abilities and Attacks, Clothing and Armoury, Achievements and Progress and etc so its not as simple as putting a character mesh selection.
Sounds like you also need to be interfacing with your save object through your player controller, and then allowing the pawn classes to get data from the controller as needed. Put it in structs for each class if you want

[trim matrix]

so you mean i make multiple player Actors ?

[solar sequoia]

yeah. make a parent character first and then subclass them from that one so that you can make them inherit as much as possible

[trim matrix]

ill test it out

is

[trim matrix]

This is quite a complicated topic. Its kind of like asking someone "How do i build a house". There a ton of design that goes into a question like that and it is not easily explained. I think you will have a very hard time trying to find someone who is willing to put in the many hours of explanation and teaching required for you to fully understand how to make something like that. I would just recommend diving head first into this and attempting to make it work in the best way you can come up with. As long as you have the basic understanding of how to use blueprints in unreal engine you should be able to get something working on your own by just being creative and using what you know.

my issue wasnt the inventory and such

my issue was how do i split the roles themself

like the roles should be a player bp or what

but ill try the parent character

and see where it goes

A parent character would work yes, although all you really need to determine a characters role is a singular varialbe called Role.

yea ill test around

[solar sequoia]

"player BP" isn't a thing BTW. There's the controller, which you should probably just use one of for now, and then the pawn/character, of which only one can be possessed by the player controller

[trim matrix]

you can set different UIs (Game HUD) for each subclass right ?

[solar sequoia]

HUD isn't supported anymore AFAIK so I usually just put the UI logic in the character

[trim matrix]

someone told me Player BP xD

i was working on the level Design and 3D Modeling for so long

[trim matrix]

The HUD class in the framework isnt supported? Is this in UE5?

i haven't had the time to test it out

so UI for each SubClass

[solar sequoia]

Well idk because I don't use Hud objects, but I heard they were phasing it out or maybe don't recommend using it anymore

[trim matrix]

and ill use GAS and GamePlay Tags to filter between them and give each SubClass its own Stuff

[solar sequoia]

if you're new to the engine and c++ I'd have to recommend not using GAS for the moment. I'm just now getting into it after a year or more

[trim matrix]

that is lame, the HUD class is great

[trim matrix]

Design abilitys yourself from scratch in the best way you can come up with. You will learn an infinite amount more that way.

[solar sequoia]

I was trying it for a while, but then I realized that the toggle bool doesn't do anything, so I just use one master widget, basically

[trim matrix]

I am not that New and also not a pro, C++ isnt a problem, and GAS is gonna actually make my life easier xD

i am more of a Level Designer

but in Solo Projects

you need to learn everything

[solar sequoia]

if you're like 80-90% confident with all blueprint stuff so far, then I'd say try GAS

there's a lot of implicit knowledge needed for a plugin like GAS that you won't be able to find a tutorial for a large amount of

[trim matrix]

i already got my Inventory system and nearly all the systems i want

but they are not that good for Multiplayer and for sure not good for the type of game i want because they need allot of filtering and Restrictions

and from my research GAS has an amazing way to filter and such

[junior hedge]

how am I supposed to make it so when I hover over the image it does something

it says MouseEnter event but I dont know how to specify what needs to be hovered on to start that event

do I do it as a bind?

oh I need to connect the image to a button ig to create the event

NEW QUESTION

wait is there really no way I can make it so I can use both the mouse for UI and to move things around??? Looks like I can only do one at a time

move player camera

I made a input bind (Q) to release my mouse cursor, when I do that I can react with the camera but not the ui, when I click though I can interact with AI, but I cannot react with the camera

@quaint geyser

[warm glacier]

I have these objects and a sled. At the moment (all I could think about as a beginner) I have a static mesh attached to a socket in the vehicle blueprint and I toggle it's visibility with input. The problem is that I want to stack objects on each other. The solution I have in mind is to have a lot of sockets but that sounds like a terrible idea.
It's impossible to spawn the actor itself because I can't use Attach Actor to Actor when one is static.

Any suggestions?
A good reference is The Forest.

[quaint geyser]

You can code it manually fairly easily

In the widget

Just add controller yaw/pitch input in the lookup and turn input events.

Actually… not sure if that will work

With a mouse cursor

[junior hedge]

lmk if you find anything

[quaint geyser]

Try printing out axis values

In the turn and lookup input events

And see if I get any results

[junior hedge]

in the ones already made?

I dont have lookup binded just turning

If I have a custom player controller how do I use it in the context of a third person game? The controller has a camera and the camera is the root so I can't attach it to a spring arm

[keen anchor]

Im having problems with set vector parameter value having no effect on dynamic material instances. I had it working before when i did it by creating a dynamic material based on material index. Now im trying to do it dynamically as the materials will change (player can change material on runtime) and it does nothing now. Anyone got any ideas?
Also not sure if this will create a bunch of orphaned material instances that needs to be cleaned up somehow?

it does create materials based on the filter, it's just that the parameter does not get set

[quaint geyser]

You’re creating a dynamic material instance and never assigning it to the object

I had a similar issue

But I can’t remember how I fixed it 😭

[keen anchor]

ah damnit! But then i know where to look, thank you 🙂

[quaint geyser]

Try using the created dynamic material and set the material for the object using current index from the for loop

To replace them.

[keen anchor]

ah, will try that, thanks!

It worked! Now i need to figure out how to make it update in the correct order. Thank you! ❤️

here or in your post process volume

disable bloom and let me know if that worked

didnt work

can I screenshare it?

[sleek kite]

also disable this

alr did

TLDR: Go to Project Settings > Search for AutoExposure > Disable

repeat the same with bloom

Now you can disable autoexposure in your post processing volumes too

ok, do this

disable that

Can Macros from parent class not be used within the child?

I set up a macro on the parent class, and it works in game on the child, but then when i try to save the child class it won't allow it (the macro also does not appear in the child eventgraph add menu, and can only be dragged in from the parent

[earnest tangle]

Yes, look in the unreal documentation for the fbx pipeline page or whatever it was called, the example for it is in there somewhere

[worthy tendon]

You can add a macro library though which can be used across multiple blueprints

[quick grove]

sorry guys how can I set the PS4 controller light color?

I tried using "Set Controller Light Color" in the BeginPlay event but it doesn't work

[jagged stone]

I think i can't use a library as the Macro needs to set some variables

[quick grove]

the controller light remains turned off and doesn't show any color even if I do this

[jaunty crow]

Does this only apply after the cast has been run or is it just all the time

the whole "this will cause the blueprint to always be loaded"

[tawdry surge]

All the time.
It loads the class into memory so it can be accessed for the cast.
Casting to a character, controller, game mode, etc.. is fine because those things will generally already be loaded

[jaunty crow]

Alright cool was just wondering since adding that seems to add the whole size of my player blueprint to it in the size map which is roughly 200mb

is there a good alternative i was just gonna use tags

[tawdry surge]

Soft references, interfaces, and event dispatchers

[jaunty crow]

thanks

Quick question about geometry script (blueprint).

• the append box node has dimension inputs

• I connected a vector to those dimension inputs

• when I connect that vector to set world scale of another actor (a cube), it does not match the size of the box created by append box

• grabbing the bounds of that box created by geometry script does not work either

• i suppose this is because the append box node creates a shape from scratch while a cube already has a different scaling

• is there a way to get a static mesh have the same size as a shape spawned by a dynamic mesh ?

FIX (in case anyone is Ctrl F 'ing through the chat to find one lol)

• set the static meshes' size equal to the box you spawned

• get that static meshes' world scale and divide it by 100

• i found that out using the bounds.... dimensions are apparently the units used for actor bounds iirc

[misty pendant]

Hello, any idea how i can make the script when im unhovering to actually work? Please can someone explain how to make it work i've tried to fix it myself and didnt understand im kind of dumb

[tawdry surge]

Show more of the player code.
What you've shown should work provided the trace is working properly

[livid vessel]

I have a performance question. I have a game with an agile robot that drives across fields. Is it now more efficient to run a box trace on each block to retrieve code in the block or do I give the master tile a box collision and can then even check whether you have entered or left the field. I'm more interested in the performance than the feasibility, because I'm able to do both.

[tawdry surge]

Its probably better to use a map and look up the data based on grid position

[manic geode]

How do I disconnect this entirely?

ah that was alt+click ok

What the heck? I pressed smth and it just blocked the window

I cant press anything in it

[static timber]

hello, I would just like to display multiple text (5-6) from the same UIWidget which is all in the same place on the canvas, just hide them and display the desired text, is it possible, instead of creating a widget per text (each widget for 1 sentence).😄 Is this possible? How do you do this without bypassing and tinkering, thank you 😁

[tawdry surge]

You can just make one text object on the canvas

[static timber]

hhhm

its object and a text in a same time

[tawdry surge]

You can tick the is variable box in the details panel and then you can set the text at run time

On the widget you grabbed a text box out of the palette tab right?

[static timber]

ok but my question its possible?

but yeah "details panel and then you can set the text at run time"

[static timber]

yeah

[tawdry surge]

Yeah
So on the event graph you'll be able to get the text box reference and it has a set text function

[static timber]

okkk

[tawdry surge]

You can just make a text array and iterate over or whatever you wanna do and feed that in as the new text

[static timber]

i dont found but i have hope, and i know existence of object on UiWidget

big thanks

[tawdry surge]

Nah I was just talking about the text box itself

[static timber]

hhm hhm hhm hhm i understand that, :DDD

thanks!

[tawdry surge]

Its early and misspoke when I said object

[static timber]

ah! ahahah

Post processing

[manic geode]

ah ok, I just closed and opened the window inside the editor and it worked

some weird bug that must have been

[uneven geode]

Post processing -> yes but i have a image in a custom widget, i should create a custom material? or postprocessing options?

[livid vessel]

I've already thought about that, but I didn't want to have all the code in the player and outsource things. In addition, it becomes difficult when fields communicate with each other

[tawdry surge]

@uneven geode idk off the top of my head been a long time since I did it, but I'd look up something similar like objective markers and see how they do it.
It's not a long process as I recall

[uneven geode]

i used this for know, but thanks for the info i will look forward into it

Space: Screen instead of world

[tawdry surge]

Nice

@livid vessel in that case, line trace would be more efficient then a box unless you want data from more then one square

[marble tusk]

That's the overlay when moving a panel around to snap it to various sides of the current panel. I think the easiest way to fix it is to drag another panel over it then off it to make it go away

[acoustic cipher]

hello folks... someone have some kind of experience with "Geometry Scripts" and blueprint?

i cant refresh a dynamic mesh within blueprint no matter what i do

seems a bug to me...

[livid vessel]

Ok the thing is that I currently have a Linetrace System but when using many movable objects and stuff like this. It will be very tricky to sort all that traces and combine them to reliable code. Collision boxes are for my purpose very reliable and I would go with this mehtod. Unless someone tells me now that with let's say 2000 boxes on screen, the performance drops very sharply in comparison to masses of traces.

[tawdry surge]

2000 I'd probably rethink my approach and use a manager object with a map to avoid all that.
However you can easily test it with the profiling tools in engine

[livid vessel]

What kind of map do you mean? Like a variable map referencing every tile or like a structure array knowing every data at coordinates or something else?

[strong turtle]

Hey, whats the optimal way to create "lockouts" for example shooting a gun? For example, while jumping, disable shooting and while crouching, disable shooting? Just a big OR gate with one variable per lockout?

Hello guys! Still me 🙂
I am creating a widget inside level blueprint and adding it to viewport (pic1)
I need to get the reference to that widget inside my bp actor (pic2) to connect that object reference to my event dispatcher which i call within the widget's event graph (pic3)
I dont know how to create that reference and access it inside the BP Actor tho.. can anyone help?

[tawdry surge]

@livid vessel based on the picture I'd just have a map of the grid positions and a soft reference to the corresponding tile.
You could use a struct, datatable or data assets if you want but they can get different levels of tricky if the data isn't static

[livid vessel]

Ok thx for the advice. I havent yet worked with soft references so I think it is a good time to start learning it XD

[tawdry surge]

They're nice for reducing memory foot print

Among other things

[trim matrix]

How can I delete a Row Structure?

[tawdry surge]

You mean alter a datatable at run time?

[trim matrix]

no, I have created a Structure and I delete it but I can still see it when I want to make a new DataTable

[tawdry surge]

Oh, have you restarted the editor? Might just have not updated the list

[livid vessel]

You can make a right click with your mouse on the folder where the structure was located and choose the option "fix up redirectors in folder". This fixed it for me

[zealous moth]

Anyone have any idea how the rolling is achieved with the pill bug?

you can see that it is not 100% static centered and does roll at angles

[spark steppe]

what did i just watch xD

[zealous moth]

super pillbug sonic 64

[spark steppe]

ngl, that's pretty good animated

almost cute

my guess is they change the collision to a sphere for the rolling?!

[zealous moth]

hm could try it

the rolling is amazing ngl

[spark steppe]

the whole animation is good

could implement wall climbing and keep the wall jump because it looks funny af 😄

[faint pasture]

It would depend on if they're simulating physics or using kinematic movement. They might just be using physics

[zealous moth]

kinematic?

[faint pasture]

In that case, roll the thing up, and let this sphere collider simulate physics and roll

[faint pasture]

Like the character movement component

[zealous moth]

ah i see

[spark steppe]

yea, i would also try to use physics, while input adds some force

[faint pasture]

Yeah that looks like physics to me, at least the rolling bit.

Those animations are top notch though

Trying to find angle between two vectors so im using the dot product and the arc cos

but why is it not working

it only gives -90 and 90

i want all the values

assuming its because im using the mesh forward vector

basically i want the mesh to rotate to the camera's yaw when i press a button

[cyan bone]

i will repost to not interrupt your question

[fierce birch]

all good dude

I tried but it's not fixed 😦 thnx anyway

I need to convert these skeletal meshes into one static mesh at run time.

Is this possible? How is this done best?

[limber parcel]

why are u not using the built in rotation shit?

[livid vessel]

I have tried with adding collision boxes and so far the the impact seems really low. I only lose round about 1 Fps every 100 tiles.

[fierce birch]

what do you mean

lookat rotation?

set actor rotation?

they dont work

[fierce birch]

still need to find the angle though

and thats what i did with the acos of the dot product but its only 90 and -90

[spark steppe]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Math/Rotator/FindLookatRotation/

that one should actually work

[fierce birch]

i did that

didnt work

[spark steppe]

doubt

[limber parcel]

i dont understand why you are trying to use angles in the first place

from what ive seen so far everything is done with vectors and rotation shit

[fierce birch]

i have a character that is oriented the wrong way when i aim

i want him to rotate with the aim offset to the vorward vector of the camera

i have to rotate the root bone for it to work

tried getting difference between yaw rotations and that didnt work

[limber parcel]

well then what Ben said

[spark steppe]

so you have an offset

[fierce birch]

yea

playing when i aim

[spark steppe]

so most likely the forward vector of one of your actors is wrong

[limber parcel]

are u sure u have set the proper roation in the mesh?

they usually are 90° off by default

[fierce birch]

not sure

[limber parcel]

make sure it faces the direction of the blue arrow

[spark steppe]

the blue arrow is Z 😄

dont make them face Z

[limber parcel]

works fine for me

[fierce birch]

the yaw rotation

and yes it is oriented that way

i thought you meant in game

[spark steppe]

oh that arrow

how do you set rotation on the actor?

[mental trellis]

Set Actor Rotation

[fierce birch]

well i was rotating the root bone because i cant set actor rotation

because the mesh is the one rotating

[limber parcel]

maybe this helps

[fierce birch]

but the dot product and the acos should have worked

i attached an arrow component under the mesh and its rotating with the camera

find look at rotation works but not all the time

[limber parcel]

unreal just does weird stuff sometimes, yesterday i added a moveto into my building placement function and apparently it created an infinite loop for no obvious reason

[fierce birch]

hmm

i mean im at a loss

[limber parcel]

what should i say, i have to change my whole AI now because of this retarded issue

try using a transform if the rotation shit doesnt work

[fierce birch]

so why if i search up a function or what ever it doent show up sometimes

using ue5

never done this in ue4

[limber parcel]

sometimes it only finds them from dragging a pin, sometimes it only finds them from right click

[fierce birch]

but when i uncheck context sensitive it doesnt appear

[tawdry surge]

Usually means you didn't compile the BP the function belongs to since you made it

[vast crow]

Core redirects doesn't work anymore in 4.27? Documentation (https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/ProgrammingWithCPP/Assets/CoreRedirects/) is very unclear, I'm having 10 retries every time I have to use it
This time I seem to have tried every combination, for example:

[CoreRedirects]
+PropertyRedirects=(OldName="Creature_C.hp", NewName="CurrentHP")
+PropertyRedirects=(OldName="Creature_C.mhp", NewName="MaxHP")

where at left are variables in blueprint (at path /Gameplay/Creatures/Creature_C), and at right are C++ base class variables

Doesn't work => I'm deleting the variable in blueprint and all usages are removed too for some reason

[cyan bone]

Im trying to convert a Character or its skeletal meshes to a Static Mesh at run time.
What should i do?

[spark steppe]

most likely you should forget the idea to get anywhere with BP only

unless there's a 3rd party plugin which exposes some methods for that

[covert stirrup]

Afternoon peeps! what would be the best method to stretch a mesh (cylinder) to match a line trace path?

[faint pasture]

Is the line trace path straight?

Is it one line trace or a bunch in a curve

[covert stirrup]

It is a straight path yea and just a single LT. This is how I have done it so far but I think I will look into a UI drawn method instead, not liking the perspective of the line going thinner due to 3d space

[faint pasture]

What are you trying to do? Bullet traces?

laser?

[covert stirrup]

basically when an element is clicked, it is to draw a line to the UI to highligh a text field -- just for a bit of pazzaz and style

Experimenting with a 3d space version has made me decide against that method 😄

[faint pasture]

Yeah if it's in 2d on screen, do it through the HUD/widgets/drawing.
Our current project has most of the UI in 3d but it's a personal choice

[covert stirrup]

That sounds cool, takes a lot of updating to keep it tracking right so it's something that can be cut if necessary

I mean if it's gotta update every frame, it gotta update every frame. Everything that changes per frame is driven by a tick, somewhere. Don't be scared to tick things that need to.

We run almost 2000 line traces per tick in our current project in the worst case, you can do a lot in a tick. But only do what you need to

Does anyone know how to do stuff like custom directorys with setting.dat or txt files in?

[upper cove]

any suggestion guys?

I was brainstorming the whole day about this. I have modular characters with many types of armour, weapons and helmets Skeletal meshes.
Then i have armies made from these characters but converted to instance static meshes (with the convert character to static mesh).
So armies -> cheap ISM that use lerp only. Real character that i can posses -> skeletal meshes (just the king or the general).
These skeletal meshes being modular can be changed, so i can equip my king with different armour and helmets.
And that lead me to try to do the same with armies of ISM soldiers. But they are not skeletal meshes, so i cant just swap them like that. So the only option im seeing, is convert every single skeletal mesh of body parts to a static mesh (not run time).
Then i can form my ISM armies made of these converted static mesh helmets. Swap their helmets, etc... The only issue is that instead of 1 soldier ism, i will have all parts of the body as ism. So when i lerp the soldiers ism, i have to lerp all body parts, so its 1 soldier lerp vs helmet, armour, weapon, torso lerp.

you can select an actor in the editor and convert it to a static mesh

if that's all you need...

[cyan bone]

Yup. But that converts the whole character. Then i cant change its armour, or helmet.

But thats what im doing for now.

It's such a tech art challenge I'm having trouble wrapping my head around it. It's kind of beyond the scope of mere #blueprint... All I can say is watch every video / read every article possible on games that have tackled similar challenges and learn about the strategies

Dig around the UE marketplace and see what kind of tech is there

I remember you were throwing around some pretty big numbers for armies

And if they have individually customized armor sets, that's going to be a lot of draw calls unless you figure out something really clever

[faint pasture]

In plain English, what is the end result you're trying to achieve?

[quick grove]

guys do u know anyway to set the dualshock light color?

How do you increase friction on a ball with physics?

[faint pasture]

Make a physical material and modify it's friction

But do you mean sliding friction or air drag?

[zealous moth]

rolling i guess

[faint pasture]

Yeah that's the physical materials

[zealous moth]

in the rolling ball template there iis a bridge

ball when stopped keeps rolling off

[upper cove]

Hey @faint pasture i'd need to get a reference to that widget in my bp actor in order to connect it to the target pin of my event dispatcher

[faint pasture]

I mean in terms of the game. You want to add a health bar above something, show some dialogue, what?

[faint pasture]

Sliding friction won't stop that. Is the bridge sloped AT ALL?

[zealous moth]

it is

[faint pasture]

So why wouldn't the ball roll off

[zealous moth]

I don't want it to 😛

[faint pasture]

Balls roll down slopes

[zealous moth]

I'd like for it to stop and stay stopped

[faint pasture]

Does it roll or slide?

[zealous moth]

roll

[faint pasture]

Ok so the root of this is you want the ball to NOT rotate when you're not giving input

Or at least resist rolling

[upper cove]

oh ok i need it to change the material attributes of a specified mesh (that is inside my bp actor) pressing a button on my widget

[spark steppe]

could try to increase the sleep threshold

so that the physics is put to sleep earlier
