I want some level thing going on

Not in fps character bp

[faint pasture]

oh nvm I thought Level BP was removed in UE5, might just be gone with the world composition or whatever the new system is.

I never use Level BP so can't help you there.

[pine trellis]

is iit possible to find the gravity direction from an impact normal and if so how>

[fallen glade]

gravity direction is always down right/?

[tawdry surge]

Always seems to be

[fallen glade]

good to know everything is ok after all

[faint pasture]

ya gravity is down

or do you mean the down slope/gradient?

The cross slope direction will be Cross(PlaneNormal, Z)

and the downwards gradient will be Cross(PlaneNormal, CrossSlope)

sign convention and right/left handedness will change your order of arguments but it's that.

Gradient = Cross(Cross(PlaneNormal,Z),PlaneNormal)

There might be a shorter way to calculate it but my vectors are rusty.

Oh wait, there's a ProjectVectorOnToPlane, use that.

[fallen glade]

Is this for ricochet? I think there is a node for it

[faint pasture]

Ricochet should be a reflection not a gradient

This is prolly for rolling down a hill or wahtever

[fallen glade]

Is there a way to setup a bind to return it's target?

[silk cosmos]

Yoy can always use up vector * -1 to get gravity direction. Default ue gravity is always downward

[silk cosmos]

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/EventDispatcher/

Refer to this article. There is a section catered towards custom events

[fallen glade]

I know about dispatchers but I can't do that with in this case right? The audio component can't be tweaked

@silk cosmos

[glass magnet]

Hey yall, so I was trying to figure out a way to set up my magic system where its module and you can add things together to make a spell. How could this be achieved?

[faint pasture]

However you want it to be

[fallen glade]

A bit too broad question, what do you actually need?

[glass magnet]

fair point

ok so if i set up a base object how can i add to the base using parameters

[fallen glade]

have you done any bp work before @glass magnet ?

[glass magnet]

ye

im still new

[silk cosmos]

So I haven't used event dispathcers very much for the stuff I work on. However ypu should be able to add an input into your dispatcher and when you call it, you can plug in the target you would like. Then on the bind right click the event input and do create custom event and it should create an event with that input. Pardon me if this is incorrect, like I said I don't use them for what I work on.

[fallen glade]

I could but this bind is premade it's out of the box like that and I can't tweak it

[silk cosmos]

Ahhhh. Then I'm not too sure if you actually can do that. Sorry I couldn't help much

[glass magnet]

a better example i can use is like 2019 god of war, they have the runes you can add to your weapon, how could i achieve the same thing?

or what would be ways to achieve the same thing

[silk cosmos]

One possible idea. You could add the audio component to an array. And then on the custom event loop through the array maybe there's some way to check the current playback position or if it's currently playing and then updating that component if it is not playing. That's the only idea I can think of

[fallen glade]

Very nice Thanks @silk cosmos

[silk cosmos]

Probably create a parent class something called modulator or whatever you want and then children classes for different modulators. Then you could check for modulators and get the buffs they provide and apply them.

Let's say one applies a speed boost. You'll have a parent class called modulators, then a child class called speed modulator. Then in the player character, you can have a modulator array stored as a variable and then add or remove from that array whenever necessary. When you add to the array you'll want to loop through it and apply the buffs for that modulator. And ditto for removing, but then remove that modulator buff.

[glass magnet]

Ok yeah I'll look into it makes sense

Thank you

Im trying to learn and not watch tutorials but asking people for help is fine x.x

[silk cosmos]

I cant watch tutorials lol I get too bored

[glass magnet]

That's why I watch them in 2x

Besides it's much more rewarding to figure it out yourself

[faint pasture]

mah man

[rotund marlin]

Is there a way to get a client own mouse position just? and not the servers or such

aiming to rotate an actor so it looks at mouse (2d) on a replicated actor

[glass magnet]

I don't like looking up tutorials for the specifics like this this stuff I feel like I have to figure out on my own

[faint pasture]

The only mouse position is local. What's the actual problem?

[rotund marlin]

https://gyazo.com/fe25fca8a70b97b7e057ee63734c2345

The server can change the actor rotation of the users

[lime moat]

anyone know if its possible to edit constraints within BP?

[faint pasture]

Then don't have the server do that.

[rotund marlin]

its set on the actor itself, the one rotator

and i dont run a "run on server" for it

[faint pasture]

Yes, but it doesn't have to be replicated

[rotund marlin]

its not, only thing replicated is actors movement

[faint pasture]

Then it's replicated. What is the desired behavior here, what are you trying to make?

[rotund marlin]

So, each clients actor faces direction of mouse, including the server himself counted as a client

[faint pasture]

What are they, pawns?

[wraith cave]

any idea why my pawn isn't rejumping? My blueprint script seems perfect
I disabled jump after it did it once on top and then i toggled it on event hit but it isn't working

[rotund marlin]

Sprite pawns yes

[faint pasture]

So you want all pawns on all machines to look at the local mouse? Or do you want each pawn to be controlled by it's OWNING machine's mouse?

[rotund marlin]

owning machines mouse

[faint pasture]

Do you have "Simulation triggers hit events" or whatever turned on?

[faint pasture]

Then you need to send that to server and let it move them.

[rotund marlin]

so.. Server and run to owning client with the mouse-data?

[faint pasture]

No,
Client sends data to server.
server moves stuff
Everyone sees it

[wraith cave]

nvm im dumb sorry to trouble you with a silly question

[faint pasture]

If you're using ControlRotation and Character then there's some instant local prediction stuff it can do for you

@rotund marlinWhat's the game design, is it like a top down shooter?

[rotund marlin]

its side-ways fighter

[trim pollen]

dumb question, but how do I create the node in the middle (target->child actor)?

[silk cosmos]

Is the child actor a component. Yo7 should be able to see that class in the component details

[faint pasture]

That's a cast of a Child Actor Component's (named child actor in this case) Child Actor to Thingy

so a child actor component has a child actor

[rotund marlin]

This is the entire line of it, https://gyazo.com/be373a70c70ab1d1d035454db525e271 my way of tyring t osolve it

dont mind my italian dish.

[faint pasture]

Are you using Character or Pawn as your base class?

[rotund marlin]

pawn,

[silk cosmos]

You might also want to note that child actors can be quite buggy especially when updating the class at runtime and while replicating. So depending on your project you might want to instead spawn an actor and use that

[faint pasture]

K you'll need a replicated variable AimDirection (rotation or vector, I'd prefer vector) and be sending it from client to server on tick.

Then later in the tick, look towards AimDirection

[rotund marlin]

<.< why did i not think of aim direction

[faint pasture]

Always start with the data. Think about the minimum amount of data needed to represent your actors.

Typically it's at least a location and a direction

[faint pasture]

Wait you might not need this if the actors rotation IS the aim direction, depends on how you're wanting to do things

but either way, an unreliable RunOnServerEvent passing over some data (mouse position, aim direction, whatever) on tick is the trick here

The server needs to know what direction you wanna point

[trim pollen]

I have a child actor component reference... If I drag off there are no options for casting to child actor

[faint pasture]

You're skipping a step. ChildActorComponent -> Get Child Actor -> Cast to whatever

[trim pollen]

ah I just realized that after I typed it haha

[faint pasture]

Don't use child actor components though especially if it's multiplayer unless you're doing something dummy simple.

[trim pollen]

good to know

i think it's a simple enough use case but will keep that in mind

[faint pasture]

All it is is a component that spawns an actor when itself is created, you're getting THAT ACTOR and not the component itself.

[trim pollen]

thank you

[trim matrix]

anybody how to attach my vfx to my character?

its spawing in the center of the game

[untold fossil]

I have super annoying weird engine bug. For some reason I see a class multiple times in every drop down in the editor. The class only exists once in the entire project, but for some reason the engine thinks there are duplicates. How can I fix this? It's insanely annoying as I don't know which is the correct class and it always takes minutes to figure out the right one. How can 4.27 be this broken? Like for real....

project is full blueprint so far

does that require a reload of sorts? I already rebuild the entire project as well

nope

using VS

[gentle urchin]

Smells hotReload

[untold fossil]

there is a bit of c++ code but nothing that I actually use in the project

there is code though yeah

no I closed it fully

before

the duplicated class in question is a blueprint class btw

what do you mean with recompile? Is that not the same as rebuild?

I tried both build and rebuild

neither worked

Also tried compile in the editor

didn't work either

Is there a way or does anyone have an idea where the second duplicated version is coming from? Like is there some kind of hidden files I can see. The engine must be getting it from somewhere right?

Perhaps if I can find it in an unhidden state I can remove it or something?

[faint pasture]

Are you spawning it at runtime?

[untold fossil]

https://gyazo.com/5237e0fbf4c1042184a93d0d91eb0b0a

😢

Why Unreal, why 😦

[tawdry surge]

Wrong variable type

It tells you that

[untold fossil]

yes but there is only one bp_planet in the entire project

but for some strange reason engine thinks theres two

[frosty linden]

Hi guys, I know yall probably get hundreds of casting questions per day, but I could really use the help

I'm trying to get a reference to what weapon the character is holding so that the AnimBP knows what a specific socket's transform is

[rotund marlin]

oh yeah adriel i should prob mention my pawn does not rotate with controller at all, nor control camera's, They're stuck in place so dunno if that changes the aim rotation

[gentle urchin]

Tried clearing temp folders?

[untold fossil]

havent tried that, good plan!

OMG that fixed it

@gentle urchinly 😘

[wraith cave]

How do I cap my impulse so that my ball doesn't fly with high speed movement?

[frosty linden]

Have you tried the Clamp node?

[wraith cave]

Kinda a new to ue blueprint tried searching stuff didn't found any solution

[wraith cave]

lemme try

[silk cosmos]

After the add impulse use get cmc and set velocity to your cap

[wraith cave]

let's go it worked

but my ball is still stupid gotta tweak some settings

thanks for the help! 🙂

[wraith cave]

lemme try this too

[rich jungle]

I want to make a grid of tiles of 10,000 x 10,000 actors, but I'm not sure if this is going to be an issue performance wise.

Is there a benefit to using objects instead of actors and having the actors inherit visible properties from the object instead?

[dawn gazelle]

What goes in those spots is a reference to the object that you're trying to access.

[rich jungle]

I don't think a player would ever see more than 1000 actors at a time

[cyan bone]

I created a curved spline component using 3 points. But its not visible in the game. I read that it needs mesh to be visible.
But im only being able to do that with Spline Mesh Component. Not with just a spline (line). So how do i make this happen? Like converting a spline into a spline mesh component?

[silk cosmos]

You'd probably also want to check if current velocity is great than or = to the cap as well

[dawn gazelle]

An object doesn't exist within the world space. An actor does. You would need at least 1 actor to be able to represent something being displayed in the world space. If those tiles are all the same mesh, you may want to consider using instanced static meshes on a single actor.

[mental trellis]

Or loading levels in and out?>

[tight schooner]

1 million actors

[rich jungle]

Yeah, most of them would be "dormant" not seen and not needed immediately

[mental trellis]

100 million, seanny.

[tight schooner]

100
MEELEION
actors!!

I wonder how long it would take to spawn that many...

[rich jungle]

each one would be pretty simple in what they do, it'd be literally just a square with a texture and a couple data pointers

[dawn gazelle]

raises pinky to side of mouth

[rich jungle]

spawning that many is definitely an issue

I can definitely whip up code to represent the tiles and only have 1000 actors representing the 100m tiles in database

[tight schooner]

even updating an instanced static mesh array of 100M....

via BP

[rich jungle]

I don't think it'd be updated once spawned

it's a reference to objects that would be updated

those would never need to change

[frosty linden]

How would I go about getting that reference? I understand it for the player character because I can just "Get Player Character" as well as widgets since they return the object on creation, but I cannot figure it out for regular actors

[rich jungle]

regardless of how big I manage to make it, are there performance benefits for an object compared to an invisible actor?

[dawn gazelle]

That depends on how the object is related to what it is you're trying to do. Eg. Is the weapon a child actor to your character?

[frosty linden]

In this case, the weapon being accessed would be a child of a parent weapon class, and the AnimBP is (trying to) access both the character and the weapon

[dawn gazelle]

Not really. The performance issue you would find would come in terms of how many actors and/or how many meshes/materials.

[rich jungle]

That I'd have on screen?

I'm only intending to let the player see maybe 1000 of these tiles

but the actual game world would be much larger

[dawn gazelle]

No. Actors off screen can still cause performance issues depending on how they are set up.

[rich jungle]

Seems to suggest I should be using an array of objects with a much smaller group of actors that represent them in player vision

[tight schooner]

Spawning 100M actors/components/things is such an edge case I'm not sure if anyone knows offhand. Might be worth looking into "how do I make Minecraft in UE" because they face similar challenges. Modern versions of UE automatically batch draw calls, but I wonder about occlusion culling performance and stuff with that many actors... Those are better questions for #graphics I suppose. But outside of the actor/component/etc. upfront spawn cost, that may be the main source of perf impact.

Maybe "how do I achieve what I want to achieve without actually spawning 100M actors/etc." is a direction to go in

UE has a lot of systems for that... HLODs and such

[rich jungle]

that answer is what I'm looking for tbh

[mental trellis]

You could spawn 1000 and, as you move, simply move the actors that go out of visual range to become the ones that are about to come into visual range.

[rich jungle]

if actors are a performance issue, I use objects and batches of actors to represent visible tiles

[mental trellis]

You probably want ot look into moving the world rather than the player too. You'll probably hit weird bugs out at the edge of the universe.

[rich jungle]

instead of letting unreal deal with it

yeah

my idea was more or less how minecraft handles things

3x3 batches of visible tiles

and what the actors represents shifts

so as the player walks into the new batch, the batch behind them is unloaded and the batch in front is loaded

[flat coral]

Is there a way to break a while loop in BPs? I tried setting it to the value of a bool that can be changed elsewhere but that seems to not get updated

[mental trellis]

Use the break pin?

[flat coral]

Where?

[mental trellis]

Well, okay, set the condition to false 😦

Is there not a break node?

[flat coral]

WAIT this actually is working! Well it's not working but the printout is. It just... wasn't before?

[mental trellis]

Sometimes... it can take a while.

[flat coral]

Oh no it failed quite quickly

just, in the wrong way 😛

Ok so look at this absolute garbage there MUST be a better way

[mental trellis]

Use cpp

[flat coral]

The goal is to take an arbitrary actor and find the probably-correct component to apply physics forces to

[cyan bone]

https://blueprintue.com/blueprint/rhjg86si/

Im trying to create a spline in the construction script and add spline mesh component to it that follows through its path. The spline is done, its just a simple curve. But then i dont seem to be able to make the Spline Mesh Component. What am i doing wrong?

[flat coral]

Ideally I'd let the parent actor just tell the component what component to apply physics to, but for some reason if you expose a PrimitiveComponent variable in an ActorComponent the actor can't set it in BP

So I have to do this stupid crap where the actor component tries to find the right component in its parent

[tight schooner]

I'm confused by that graph, There's a return node on the loop body which, if this is a function, breaks the loop (and stops the function) IIRC. FWIW, for any actor, you can Get Component(s) By Class

so if these are just components of a particular actor, that'd be a more straightforward way. Or you can maybe use component tags if you want it to be metadata-driven (get components by tag)

[flat coral]

The return node only works if it actually finds something. The break is needed if there are no valid components
And the problem with GetComponentsByClass is that it can return multiple and then you don't know which to use. The assumption with this approach is that the highest-level valid component in the tree order is likely the correct one

[tight schooner]

Tree order, huh. Is GetComponentsBy... randomly sorted?

[flat coral]

Far as I can tell. It's definitely not tree sorted, the first one when I tried it was completely random

Well no it was a random leaf node, I dont know if hte order is STABLE or not but it is hard to predict.

Tags are probably what I'll end up going with if no one has a better idea, since this approach is a monster. But I dislike tags because A. They add more work to making the actor and B. you can conceivably forget to add them, or add them to two by accident

[teal jasper]

hello i have a skeletal mesh component using mesh A and want to change it to mesh B at some point in the game. I'm using the Set Skeletal Mesh function and it changes the mesh from A to B, but the materials are the same used in A, how do i tell it to use the materials of B?

[wintry topaz]

any idea why end overlap would be firing constanly

[flat coral]

Actually this is worth asking as well, why can't I set this variable to the StaticMesh in this pawn?

[paper galleon]

Because there's no static mesh object instance in the editor

[burnt canyon]

Can someone quickly remind me how to add velocity or rotation for example X amount every second with delta time, my brain has gone blank as usual

[paper galleon]

Amount * deltaTime

[burnt canyon]

Thought so, I think I might have mangled something else :p ty

[tight schooner]

on tick, ofc

[paper galleon]

If you want to add 500 units in one second multiply 500 by Delta and add it every tick

[wintry topaz]

object hits the ground and then begin and end overlap just keep firing

[burnt canyon]

Thank you, I will note this in my notepad

[flat coral]

I dont understand this answer, there's the static mesh component right there. It's a cone

[dawn sparrow]

That's a static mesh, not an instanced static mesh

[paper galleon]

Same answer. The static mesh component object instance, for all intents and purposes hasn't been created yet so the auto space component does not know about it.

It's only a member variable in the actor class

[paper galleon]

*static mesh component

[dawn sparrow]

i have a blue print triggering an event on an actor blueprint, but when i duplicate the actor in editor, only one of them fires the event

how do i set it up so all of them would respect the key input and fire the event at the same time

[flat coral]

Have you set both of them to not consume the input?

[dawn sparrow]

i dont know what consuming input means

AH

sir grinningpariah

i salute u

[paper galleon]

While you are in the blueprint class, nothing has been created yet, not the actor not the components

Technically, they have been created, for some assets and editor magic. But to you, it's practically the same thing as having the actor class in C++

[flat coral]

Is there a way I can create a field in an ActorComponent that the parent can reference in the way I'm trying to? or is my only hope passing in the value on BeginPlay or something

[flat coral]

That's a useful menu too. If you don't need to fuck with ExecuteWhilePaused yet, you probably will later.

[paper galleon]

Begin play, I'm afraid.

Even the character movement component has to set the updated component (the component that moves i.e. the capsule)
In its begin play.
It doesn't know about it in the blueprint yet

[flat coral]

Wait in the BeginPlay of the CMC or the character itself?

[paper galleon]

I can't remember the exact one. It might have been multiple places though. The latter ones for confirmation.

The begin play of the components come after that of the actor if it helps

Or is it the other way around.

You can use a simple print string to check

[flat coral]

If there was a way to do it in the movement component that would be ideal, what I'm trying to avoid is having to do setup work in each actor that uses the component. I want adding it to be the only step.

[paper galleon]

Yeah the component would be best for something like that

[flat coral]

But as far as I can tell, doing it from the movement component still runs into the issue where it has no way of knowing WHICH component of the actor to pick

[paper galleon]

You can. Get owner, then get components by class.
You can use a tag to identify the particular static mesh if there are more than one.

Granted, the CMC only works with the character which is guaranteed to have only one capsule as the root

[flat coral]

Adding a tag is easier to miss and actually more work than just doing this, though.

[wintry topaz]

So i am finding out the if I have a object that falls the on overlap and exit overlap are constantly firing because the floor is moving... Is this normal. if the floor is not moving it does not have the constant fire issue

[paper galleon]

In the actor begin play eh? Makes sense

[paper galleon]

I presume it is. Especially if it is moving through stuff

[wintry topaz]

well i have a cube on a moving floor when the cube falls and hits the floor it gets called once if the floor is moving it gets called every frame

is there no way to fix this?

you can have on begin and end with two moving objects?

[lime moat]

anyone know if its possible to edit constraints within BP?

[paper galleon]

This is normal behaviour.

[paper galleon]

You asked this question a couple of days ago.
A Google search would have yielded this https://forums.unrealengine.com/t/how-to-set-lock-position-and-lock-location-on-component-in-c/348373

GetBodyInstance.

[lime moat]

I've read over that post along with a handful of others, that post is referring to C++

[paper galleon]

Have you checked that there is no BP version of the relevant function?

[lime moat]

yeah, me and others cant find any BP ways of doing it

[wintry topaz]

is there any way around it? or any idea of other solutions

[lime moat]

I'm guessing there isn't a way, but is seems strange. So far everything I've seen as a setting within a BP has been able to be changed, but I cant find anything

[paper galleon]

Might have to dive into C++ then. A function library should suffice

[lime moat]

Yeah, I figured that might be the case. Just was hoping to avoid C++ xD

[paper galleon]

I can't really think of any. You'd probably have to redesign some stuff.

[paper galleon]

😅 at some point, it's inevitable

[lime moat]

I suppose so! 😛

[wintry topaz]

so i have a room that is spinning
and a box that bangs around that room..
but if the box falls and hits for floor it should play the hits sound
and if its sliding it plays the sliding sound

so when box hits floor on enter collider should be called so then it switches to slide sound and if it exits the collider it makes it so the falling hit noise could be played again

[paper galleon]

Hmm. I can think of something but I'm not on my PC and the solution is not very straightforward.

I'd suggest you use a trace on tick, if the trace detects the box. Check if the box is already sliding through a IsSliding bool in the box actor.
If it is sliding, don't do anything, if not tell it to slide.

If the trace does not detect anything, check that the box is already bouncing. If it is, don't do anything, if not, tell it to bounce

[earnest mango]

PrimitiveComponents have the SetConstraint function, which has limited functionality in locking position, but has nothing for rotation

[flat coral]

New issue, I've got this physics-powered pawn that should be smoothly moving around the map, but for some reason it's extremely jerky. Like every half second it will jump forward a few inches, overall moving incredibly slowly even though it thinks its velocity is pretty fast.
The weird thing is, my tick rate on this pawn is pretty good, way more frequent than it's moving. And I'm using the exact same system to move my player pawn around and that pawn moves smoothly.

[lime moat]

That was the first thing I found before my search online began 😛 although now that you mentioned it again, I might be able to use it, if it will actually override and settings I currently have with my position

[wintry topaz]

oh interesting.. im a unity dev that just started to play around with unreal today so alot of this is over my head

[flat coral]

The other weird thing is I've added different free-floating physics objects before and they all move smoothly, I'm definitely not at some kind of physics solver limit

[paper galleon]

Woah. It's a lot to take in then. Sorry, I'm not sure how much more help I can be

[wintry topaz]

no its all good.

[paper galleon]

I hope it doesn't discourage you.
Unreal > unity yunno? Lmao.

I'm joking, not joking.

You just need a few more lessons on how unreal works is all.

[wintry topaz]

though i am finding out why more an more "cool ue5 videos" are just static scenes
no wonder everyone just makes static beauty scenes.
throw in some nice 3d objects throw post processing on it animate a camera.. call it day

the lighting and all is amazing

[paper galleon]

I actually have that same issue with all these tech demos.
They focus on the graphics and not really gameplay, it gets frustrating at times

[wintry topaz]

100% agree but clients see a nice picture and say we need to be using this...
"do you really need to use unreal 5 to sell cabinets.... really....."

[paper galleon]

😆

[glass magnet]

sorry its been a minute but ive been at school. So just to confirm id make a child actor that has specific buffs in it etc then i would use the parent class as the array and if i added a module to something it would add and remove the child of the parent?

[flat coral]

Okay this is weird, I turned off my AI for this and just manually set a target destination for the pawn, and suddenly it started moving slowly.
But why is the AI running affecting how smoothly my physics processes?

[wintry topaz]

but good talk and thank you for your advice. and respecting my opinion... you do get that much these days 🙂
is there any youtuber or anyone that has great starter videos for this stuff?

[glass magnet]

whats been goin on

i like ryan laley personally '

if youre talking about starting ue4 thats where i started

but it looks like youre talking about ue5 so nvm 🙊

[paper galleon]

I don't really like to recommend tutorials. Many of them make it easy to cultivate bad habits.
But Ryan Laley is good. CodeLikeMe also, Reid's Channel.

They are certified unreal engine instructors

[glass magnet]

it is good to learn on your own

[paper galleon]

Jinx

[glass magnet]

i think ig you just start then a tutorial is fine

like to learn how stuff works yk

[paper galleon]

Exactly

[glass magnet]

i like to think of unreal as a visual representation of code, kinda cause thats exactly what it is if you use blueprints

x.x

[flat coral]

Blueprints are code, you can never escape. 🙂

[glass magnet]

hey i am self aware

also tbh as someone who cant read i love blueprints

it makes my kindergartener brain smile

i can read and im not a kindergartener

[wintry topaz]

i think unity just introduced some visual coder... dont like it or any visual coding really

[glass magnet]

really?

also to my knowledge you dont have to use blueprints its completely

whats the word someone help

preference

and i could be wrong maybe theres advantages to using code over blueprint or vice versa

[earnest mango]

C++'s big advantage over BPs is that it executes a lot faster. At least as of like 4.16, Epic said BPs are 10X slower than C++.

[glass magnet]

slower as in?

[earnest mango]

Takes longer to execute the same code

[paper galleon]

Playmaker and Bolt. Never used them. They're not really needed in my opinion. Just Unity's answer to blueprints

[glass magnet]

really?

like is it a once you export thing or is it only noticable once you have a lot of code

[paper galleon]

The difference is quite negligible in most cases. Seeing most BP functions are wrappers over cpp

[wintry topaz]

yeah i think those were add ons and maybe unity just purchased one

but yeah that is just to answer blueprints

[glass magnet]

tbh i just find blueprints easier, more accessible, and more fun overall but again i see it as preference based

[wintry topaz]

ha like coding for Meta horizons

[glass magnet]

using my kindergartener brain

[wintry topaz]

which if anyone hasnt tried it yet is awful

[glass magnet]

wdym

[wintry topaz]

you have to do all the "coding"
drag and drop kind of like blueprints
But you have have to be wearing the oculus the whole time

im not even sure you can use a mouse or keyboard
i only did it where i had to use there controlers

[burnt canyon]

Say I wanted to move an actor forward X amount using Set Actor Location in the direction of a camera that could have any Relative Location or relative rotation, what would be the best way to do this?

[paper galleon]

You want to move the actor to where the camera is looking?

[burnt canyon]

oh nvm I done it

[paper galleon]

Ok

[burnt canyon]

Sometimes I wonder how I can even breathe 😂

[paper galleon]

Lol

[wintry topaz]

pfft my whole career is based off bad habits

[tranquil gorge]

does anyone know how i can just use a separate camera than the one attached to the main characters in blueprints. i want to use a single camera that reacts to both characters movements on screen.

[low marlin]

how do i make a box using a blueprint

[crude isle]

...

create a blueprint actor

and put a box in there lol

[lilac storm]

Hey i got a question , How to make variables so they appear in details pannel as "Defaults" like shown on the picture

[low marlin]

im very new sorry

im doing unreal engine for school

[lilac storm]

Thats okey , dont worry much ! We all started at some point !

[dawn gazelle]

Any variables added to the class normally do appear in the defaults. If you have variables categorized, they'll appear under different categories

[crude isle]

if they don't appear try compiling then it will show

[tranquil gorge]

hey bud while you are here do you have any weigh in on my previous question. i think it might be rather simple i just have no clue where to start

[formal parcel]

i'm looking to do this concept in 3d but not idea where to start - any advice?

https://i.imgur.com/eyTNcXE.gif

[dawn sparrow]

click on the eye balls on the right of variables to expose them?

[crude isle]

wdym

you want to create a new camera?

[tranquil gorge]

yes and it doesnt seem to want to use the new camera for some reason when i drag it in

[crude isle]

im confusion

[tranquil gorge]

is there anything i can show you or explain more to help you further understand

[low marlin]

uh how do i make a number input for ui

[low marlin]

whats that

oh nvm i know

but uh can i do geometry using a blueprint tho

[flat coral]

I've got this physics-based moveable pawn which COMPLETELY loses all performance if I edit its destination after it's started to move, and I have no idea why.
This is the simple test case I've arranged. If I swap to just point execution at the "SomeOtherVectorVariable" which isn't referenced anywhere, performance is butter smooth. So it's definitely specifically setting Destination that causes the issue

HandleThrust is pretty simple, just gets the unit vector in the direction it needs to go (AllowStrafe is on)

And AddLimitedAcceleration is a fucking monster, but it's a monster I'm using for other pawns without issue so I don't think the problem is in here.

Any idea why editing the value of Destination during runtime causes physics performance to sharply degrade to almost zero here?

[low marlin]

how do i get a variable from the level and use it in a widget

[lime silo]

I'm trying to cast a ray from the player to the edges of an object. any idea on how to get the edges?

[plain jay]

Does anyone here know how to get a socket tag from an object? I can get the socket itself but it allows you to set a tag. I cannot figure out how to expose the tag in blueprint lol

[edgy glen]

Hello, in the third person template I've noticed when walking forward and rotating the camera with the mouse causes the character to studder slightly on the Z rotation, would anyone happen to know why?

[flat coral]

OH MY GOD it's the rotation! if I just skip this node it's butter smooth

But WHY! How is this function tanking my physics performance but ONLY if I change Destination at runtime?!

[obtuse herald]

The PlayerController has a SetViewTargerWithBlend node which does exactly that

[tranquil gorge]

thankyou for bringing that up however when i try to use it im not sure what to set it too since i want it to be controlled by to say in short the sum of player 1 and 2's movement around the screen

[obtuse herald]

I suspect that the Rotate to Destination bool is only true when you change the destination (at runtime). Thus the branch body gets executed only then, tanking performance.

[flat coral]

That bool isn't blueprint editable though

And in fact if I set it to false, it's the same as if I skip the node. Smooth perf (but without rotation obviously, which I'd kinda like)

[obtuse herald]

I don't quiet get what you mean honestly

[obtuse herald]

Disconnect the SetActorRotation node for now and print the math results to check if there is anything weird going on

[tranquil gorge]

you want me to set the player controller as the target with the setveiwtargetwithblend node correct?

[flat coral]

Honestly seems fine to me? The Divide By Zero warnings aren't actually from this class, and none of those values seem ridiculous

[obtuse herald]

Yeah and New View Target should be your camera you want to view

[obtuse herald]

Yeah.. do you get performance problems running the print statements?

[tranquil gorge]

ok ill persue this and get back with the results thankyou

🙂

[flat coral]

Nope pretty smooth

[obtuse herald]

Weird. Setting actor rotation every tick really shouldn't tank the performance at all

[flat coral]

Hmm what if I do both

[obtuse herald]

Is your actor colliding with something while rotating?

Has it physics enabled?

[flat coral]

It DOES have physics enabled. That's by design. It shouldn't be colliding though, at least not right away

[obtuse herald]

Then ehh, idk maybe try setting Teleport Physics to true

[flat coral]

This is with rotation actually enabled AND the print statement

Here's the crazy part, that's a TON of ticks really fast right? So why is the physics simulation all stuttering?

I dunno. I'll probably re-write this function

[obtuse herald]

You could try changing the tick group inside the actor, but I kinda doubt that it will help

[tribal finch]

Is anyone available to hop in a call so i can go over the logic flow of my inventory system? I feel like just explaining it to someone will help alot incase im doing something really silly rather than posting a wall of text describing my problem. I had a good system but feel like im working backwards as Im hitting design limitations.

[icy dragon]

Why not join the Unreal Hangout VC, and probably stream there?

[tribal finch]

Is that what its used for?

[void spruce]

How can I create a Blueprint that has for example an enum and when that enum changes, the inputs changes

[finite phoenix]

@void sprucecan you give em an exam

[void spruce]

for ex, when Enum1 is selected , i display under it FName and a bool
when enum 2 is selected, display int and a string

[void spruce]

as you can see, when EPlayerEntry changes, I wanna change all beneth it

all the stuff beneth it is expose on spawn

I was checking if it is possible to do (not so much time consuming as well)

[grand briar]

I'm trying to rotate an object away from the player but the range of actor rotation is -180 to 180 so multiplying by -1 on the lookatrotation or just the invert rotator node isn't really cutting it. Probably something simple i'm missing.

[finite phoenix]

@void spruce leave c++ and make this in blueprint

[void spruce]

can you explain a bit more ?

[granite scaffold]

Hi! I have a blueprint attached as a component in another blueprint. is it possible to get a reference to the "parent" blueprint from the child in this instance?

[tribal finch]

Yes several ways what is your use case?

[granite scaffold]

ill be calling an event in the parent, but i just found get attach parent actor which somehow did not show up in my searches, which should work!

[tribal finch]

Also Components are Instanced, So each component will be independent of each actor unless you have it in a master class and all the children

Ah ok sounds good 🙂

[burnt canyon]

Is there no Get Relative Location for a Camera component?

[granite scaffold]

looks like it's working as intended, but could I ask you to clarify this a bit? not quite sure what you mean

[burnt canyon]

nvm was a bp bug

[tribal finch]

If i have two BP_ThirdpersonCharacters, they each have an attached blueprint actor component that has a health variable of 100. If i reduce the variable by 10 from one of the players, that only affects his specific component. Nothing changes on the other character, since its its own instance. If i wanted to modify the variable on the other character I would need to get a reference to the actor, then get the Component afterwards then get then set the variable inside it if i wanted to change it

[formal parcel]

i ended up figuring it out

[granite scaffold]

ahh ok, yep! that is how i would expect it to work. thanks for the clarification!

[burnt canyon]

how do you correctly calculate the IK goal in component space with a setup like this?https://cdn.discordapp.com/attachments/322374743007297537/974468308382408734/unknown.png
Between Motion controller and the Skeletal mash, as I need the offset to be in component space

[glass magnet]

how could one achieve a dark souls like bonfire?

asking for a friend

[cyan birch]

I have a BP(A) that changes some functionality based on a 'Switch on Enum' which is set to be an instance editable variable. I have created another BP(B) which I houses multiple of A. I am using the Construction Script in B to add A using the 'Add Child Actor Component' node. When I place B into my world, I cannot see the variables for A. I am assuming this is expected functionality. I would like to keep this setup if possible but I need to be able to change those variable per instance of B. Is there a way to do this? If not, what type of setup would you all propose?

Let me know if you need more context or information on what I'm trying to set up if that would make it easier to propose a solution.

[icy dragon]

Start by breaking it down to simpler terms

[glass magnet]

ok

how could someone make a rest system or

could it just be done through using a ui interface and locking a camera in a certain way?

ig for what im going for yes it could

[burnt canyon]

How would you calculate relative location between two transforms if the rotations do not align

[trim matrix]

Did you ever figure this out?

[trim matrix]

The rotation should not affect any calculations of relative location. Can you elaborate on why the rotation is a factor in this?

[burnt canyon]

Because its turning the skeletal mesh root, so that was my assumption

if I remove the rotation it fixes instantly

[trim matrix]

I still dont understand but it seems like you have it figured out

[burnt canyon]

I do not

[formal parcel]

well you'll need to reapply the relative rotation

but the distance to something, or the vector towards something has nothing to do with being a relative location or not

relative location is a vector from one location to another... A-B

[tribal finch]

Not yet no still messing with it, but iv been having fun hanging out lol

[trim matrix]

I am available to call and help if you would like

[tribal finch]

Save/load

Save game state, reload level, load game state

Game state being souls, items, opened chests etc

[glass magnet]

right

[final python]

I'm getting these package errors, and I am pretty sure it is because the varaible inside my player save game isn't used in that blueprint, it only gets set in a couple of widgets, however, I was going to go around this by just initializing it on begin play, but save games dont appear to have any events.

[final storm]

Is there away to record the player screen in run time than play it back to the player after?

If so how would I go by doing this?

[willow tendon]

is this in secinds? or is it rate?

*seconds

[final python]

I fixed it, you can add custom events so I just made a setter custom even and called that when setting the value instead of just setting the value.

[tawdry surge]

Yeah it's seconds

[forest timber]

Can I import uassets from other projects? Just had an external hard drive corrupt and I hope I can get it back\

[half portal]

Pretty sure you can browse the folders of the project and copy stuff over if it lets you access it that way

Awesome awesome, thank you

[near shard]

Is there a way I can filter variables by the name? I have an array that has multiple characters stats and id like to filter those stats within individual variables

( The Party stats adn the Hero / Lance stats )

[forest timber]

would "contains" work

[near shard]

Not for what I need, basically im gonna have the HeroStats and LanceStats inside the party stats array, within that array I edit some of the stats and would like to transfer those changes back to the individual variables if you know what I mean

[faint pasture]

Now that you learned your lesson, use source control and backups

[forest timber]

well I had a backup but it was on the same external hard drive lmfao

now I know

[small gyro]

I've been working on a editor utility widget for generating data and I'm looking for a way to copy output text to the system clipboard, there seems to be something for c++ but is there something in blueprint I can use?

[placid parcel]

Hello, I just setup a mouse sens slider for my project. It can change the mouse sens how I want it but when you go back into the options menu in game it's not set to what the player set it to. I want to do this so the player can see what they had last time they changed the setting. Any ideas?

I think I need to do a bind on the value to set it to what the sens was after the player changed it but I am lost on how to do so.

[lime silo]

are you assigning/reading the sens to a variable?

I think game instance is the place for those settings but I am very new

[placid parcel]

Yes, I can check out that method. I am a few weeks into this new lol

[lime silo]

game instance is a like a gamemode but exists for the lifetime of the game, not just the gamemode

project > maps and modes

is there a way to query the physics meshes from an object? I'm trying to find the corners of an object at a certain height for fog of war type casts

[calm citrus]

Anyone reason why this code isnt working? I shouldnt be able to sprint in all directions, I should only be able to sprint if I am moving forward

[faint pasture]

Your code lets you START sprinting if moving forward

there's nothing stopping you from continuing to sprint

[calm citrus]

But I have it set to stop sprinting if I am not moving forward

or am I reading that wrong?

[faint pasture]

The input events only fire when you press/release the button

it's not checking over time

it's a one time thing

[calm citrus]

So should I add that code to an event tick instead?

Or is there an easier way to do it

Yup event tick worked

thanks for pointing that out

[crude gull]

Any idea why the BP_FirstPersonCharacter template can use the "add controller pitch input" node while having "use controller rotation pitch" unticked, but none of mine work unless i check that box, even while seemingly being identical?

[surreal peak]

Does it have a camera component maybe?

[crude gull]

yeah, got camera components on all of em

use pawn control rotation?

[surreal peak]

Can't recall its settings but does it also have a control rotation checkbox?

[crude gull]

yup

[surreal peak]

Yeah then it might be coming from there

[crude gull]

yup fixed. wow lol. thanks.

been going back and forth from BP_firstpersoncharacter and mine over and over trying to find differences lol

[low birch]

Has anyone experienced line tracing not going to the desired endpoint because the length of it does not connect with an object? When I click while looking at an object close up it'll make the expected trace, although if I look at something far off and trace it'll fly off to the side. I assume world 0.

[surreal peak]

That would only be due to your vector math :/

It would only go to 0,0,0 if that's what the end vector is

[low birch]

cool tyty. ill give another look

[ornate hatch]

guys anyone knows where to open level blueprint in ue5?

[rotund marlin]

Hmm.. How do one pass name thru fully so everyone can see it? as seems

https://gyazo.com/bc5594a9fb67506b9627ccf4850588c1 lets server see everyone's name, "Everyone" can see their own name, but not eachother

[untold fossil]

Does anyone know / have tips to optimize garbage collection? I'm having big hiccups everytime garbage collection happens. More specifically [TFastReferenceCollector]. When I set uobject purge time to something very low like 2 seconds. I get the hiccup every 2 seconds, even though my actor count doesn't change and no actual garbage is being collected. But I'm guessing the object purge operation does something that has to loop through all of the actors in the scene which is causing the hiccup? I only have 4k actors in my scene though and the hiccup is already insane. How do games with massive actor counts manage this?

The thing is that of all the actors in my scene nearly 4k of them are persistent and should never be deleted so I'd even prefer it if I could somehow mark these actors to be ignored by GC completely, is that possible?

[trim matrix]

Just set var as repnotify and set player name in there

[rotund marlin]

Oh?

Any chance of elaborating a bit on it? not use to using notify :<

[obtuse herald]

You can play around with the GC settings inside project settings. Setting the interval to something low like 2 will only make the problem worse btw.

Also GC has a better performance overall in cooked builds

[untold fossil]

Yeah 2 seconds is just to debug it in the editor, not to actually be used in the final build

I've changed all the settings of GC I could but nothing seems to have any effect

[untold fossil]

Is there a way to flag objects or actors to be ignored by GC? Perhaps through c++?

[rotund marlin]

Also imma guess you still can't package dedicated servers thru BP only?

[tight schooner]

You could also... not automatically collect garbage at a regular interval depending on how your game is structured, and/or trigger GC manually with a BP node and thus running it at moments where it's least likely to interrupt the action

[trim matrix]

Calls onrep function on all clients. They recieve most recent var and its called on all clients its relevant to, and when they become relevant. Just set var on server, set var as on rep and put the function to set the name in the on rep

[untold fossil]

Yeah I thought about that too. But I don't see any way to disable automatic GC

I now added the objects to root (made them permanent) Let's see if that works

[tight schooner]

Can't you set the interval to 0, or if not, 999999? I don't remember offhand what's possible there

[rotund marlin]

so resonant you mean like https://gyazo.com/605a19bd07ad97bcf821da7b37083e7e https://gyazo.com/8139a64307c11530ad0c9b4f49597fec ?

[lime silo]

can you access the static mesh in a blueprint script without enabling CPU access?

[rotund marlin]

Also i'm still unsure how to handle https://gyazo.com/99ece91fd20ec4e1230b22a94b3fd1d7 on a pawn, that does not use mouse to rotate the pawn, nor aim, and mouse is visable on hud, Each client sees themself moving Every other actor's character, and server has the same issue, But it does not actually update the direction of Pawn, its just visual per client,

[icy dragon]

Have something else reference it.

[cyan bone]

How many sprites can unreal engine handle in one actor vinterping at the same time?
Lets say i have only one actor. And i put inside it thousands of sprites (small planes with 1 texture) as ISM.
So its just 1 actor with thousands of ISM.
Then i move them around. Can this handle 1 million moving?

[tight schooner]

@cyan bone I'd look into #niagara particle systems for that. A million updates is a lot of data for a BP to crunch through in one frame

[limpid bronze]

What things get detected by linetracebychannel?

because I'm trying to detect a projectile using it, but for some reason it doesn't get detected

is there a specific collision preset for things that need to be detected by linetracebychannel?

my projectile is set to overlapAll

[cyan bone]

Ok so 1 million would be too much. What about 200k ? Mind you its a simple instanced static mesh of just 1 plane.
And as your suggestion is to do it with niagara, is there any tutorials or resources that could be helpful in learning how to do this? I have no idea how could i do that in niagara, all i have done was some light effects, smoke and blood. Is there any tutorial with niagara for units?

[limpid bronze]

okay, nvm. I figured it out

[tight schooner]

I don't have any expertise with crowd systems if that's what you're trying to make; sorry. I've seen stuff on the UE marketplace fwiw

200K updates per tick is still a heavy lift with BP

Need C++ and/or Niagara depending on what you're looking to achieve

[limpid bronze]

How do you stop 2D characters from pushing eachother in the Y-axis?

I tried constraining them on the Y-axis for their capsule colliders but it didn't do anything

like when my character goes to jump over an enemy and it hits the enemy's capsule collider, my character will end up sliding in or out depth-wise

Found the solution.

[low marlin]

can i assign an id to actors?

[trim matrix]

The answer is yes, but that is a very broad question.

[low marlin]

oh

so

wdym broad

ok so i want like 9 rooms and each room has 4 doors that go to another room

[trim matrix]

Why do you need actors to have IDs? What are the IDs used for?

[trim matrix]

Where does the ID come into this?

[low marlin]

so i can identify each door

note that each room (along with its doors) are made using a blueprint

something like this (left is room IDs)

[trim matrix]

Put a name variable on the door blueprint then. Call it DoorID.

[low marlin]

wont each door have the same id then

or can u change it

[trim matrix]

An int variable then.

[low marlin]

do i need to cast or something

idrk how this all works im really new

[trim matrix]

A variable is a peice of data that you can change.

[low marlin]

ik what a variable is

but

[trim matrix]

Hence the name, variable

It changes

[low marlin]

idk how to use it from the bp

do i set the ID of each door in the level blueprint

[trim matrix]

You are going to have to figure out how to use variables right away then.

You can’t do anything in programming without variables

[low marlin]

the room has id now

int

[trim matrix]

Yep

The two most basic things you can do with a variable are

Get and Set

[low marlin]

but its not in the level bp

so idk

do i need to cast to the room or something like idk

[trim matrix]

So you get the DoorBP and set it’s ID variable.

You are working on the level bp

So to get the door BP, you can drag the door into the level blueprint.

[low marlin]

but wont the ID be the same for every door then

[trim matrix]

Not if you Set each door to have a different ID

[low marlin]

ok

so how do i do that

[trim matrix]

Get the door (drag the door into the level BP)

Then once you have gotten the door, drag of the door and type Set ID

[low marlin]

heres my weird code atm

[trim matrix]

Oh you are spawning the door I see

[low marlin]

yes

[trim matrix]

Well the SpawnActor node returns a reference to the spawned actor.

[low marlin]

i spawn roomsAmount of rooms and then spawn 4 doors in each room

[trim matrix]

Once you have a reference to an object, you can drag off that reference to preform operations on that object.

[true kiln]

Hello guys,
I'm using a teleport system for my character and nav mesh to decide if the destination is valid or not...
But I also need to check whether origin and destination are connected to each other or not to decide to do a jump action...
Any idea how I can check if my current location and destination location are connected in NAV mesh?

[low marlin]

ohhhhhh

ok

[trim matrix]

So drag off the returned object reference (ReturnValue) and type, Set ID

[low marlin]

oh shitalingding this is gonna be so hard

but fun

[low marlin]

how do i set the ID tho

from the level

since the level is making the rooms

[trim matrix]

What makes the doors?

[low marlin]

well idk

the lvl bp

yeah

[trim matrix]

Then find the SpawnActor door function

[low marlin]

the direction vars are all shuffled arrays w/ numbers 0 to roomsAmount - 1

[trim matrix]

SpawnActor Door returns a reference to the spawned door. Drag of that reference and type set ID.

[low marlin]

ooooooh

ok

i found out how

also btw this is how my game works @trim matrix

[trim matrix]

Ok

[icy dragon]

I can picture a BP setup for that 👀

[icy dragon]

You could perhaps use a seeding system (Random Stream - https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/RandomStreams/) to control the random room generation, and just remember the seed to make the doors persistent. If a no return room is encountered, clear memory of the seeds.

It's also useful for saving into disk.

[formal parcel]

whats the name of that tool for recording small videos that a lot of devs use?

[remote meteor]

you can use FindPathSynchronously()

[icy dragon]

OBS

[remote meteor]

its also suggessted to turn off "recalculate on invalidation" at the return node of that function if you dont need it

[formal parcel]

@icy dragon OBS for just recording a small vid of a portion of the screen?

i dont thinks thtas the one i'm thinking of

thats more for streaming

[icy dragon]

OBS can record as well.

[formal parcel]

aight i'll snag it if i cant figure out what the other one was

ty

[icy dragon]

Gyazo?

[formal parcel]

theres another popular app that behaves like snapshot tool but for video

gyazo only does images last i remember, thats not the one either

[icy dragon]

Gyazo can do video capture of small portion of the screen, though free account is limited to 7 secs

[remote meteor]

win+shift+g

you can record specific window

[icy dragon]

Which is Windows's built in Xbox DVR

[formal parcel]

oh no shit lemme try that

win+shift+g not working for me, I believe i have all the xbox functionality disabled

[remote meteor]

win+g is the correct one

win+shift+s for snipping tool

[true kiln]

Then how to check wheter the destination and current location is on the same area?

[trim matrix]

Action Mappings "Mouse click" and "Alt" doesn't work in practice it seems, it doesnt care that i'm holding down alt when i click the mouse

why is that?

do i need to reinforce it with the input action somehow?

writting a little tool, for better blueprint reparenting

probably including matching/suggesting and checking /making sure if its valid

[jolly cairn]

Hi all, wondering if someone can lend me hand with something.

I have a blueprint called BP_Gun, which inherits from BP_Item. I have a sphere cast set up to detect if the player is in range of it and all that jazz, just need help with calling a function from the BP_Gun's parent class. Essentially what I want to happen is the player press E on the object, it then calls the pick up function

if that makes sense

just confused as to how i get it to call that event (even tried as function too)

[serene tundra]

well u should try detect from the items point at fist point, since when u have many items they all have to check

instead u should google how triggers work

basicly they fire, when some object enters them. then u can check if its a player

[limpid bronze]

How would you do a flickering sprite in blueprint code?

[jolly cairn]

thats not what im after

[serene tundra]

another idea would be to scan around the player, when u press e

[jolly cairn]

im not doing hit detection or anything

[serene tundra]

for objects which can be picked up

[jolly cairn]

I have that already set up, it's calling the event in BP_Item that i need assistance with

literally just want to know how i can call an event from that actors parent blueprint

[serene tundra]

?

cast it to the parents class

then u can call the functions from the parent class

[jolly cairn]

this is the event i want to call. This is on BP_Item. BP_Gun is what is placed in the game world and inherits from BP_Item. I just want this part of my character controller to call that event

[serene tundra]

yes cast

[jolly cairn]

that has worked

thank you

[serene tundra]

ur welcome

[wispy sapphire]

Does anyone know whether there is a variable you can use to change Class in the SpawnActor node? I had hoped to just use a string xD

[grand valve]

SpawnActor node has an input called ActorClass that you can promote to a variable

You can use an enum with the select node to choose a class depending on an enum?

[jagged stone]

Does anyone know if there is some kind of reverse Switch? So I have an custom Enum with 5 values. I want to have a node where there are 5 input exec pins, and then 1 output exec pin and 1 value pin...so the value pin will be set based on the input exec path

[foggy escarp]

You could do exactly this with a macro

[jagged stone]

But then if i update the enum i'd have to update the macro manually too

Because I'd have to manually create an input pin for each Enum value right?

[foggy escarp]

Why do you need 5 execution lines in the first place?

Only one execution pin would be active at any one given time anyways.

[jagged stone]

I have something like this, but i just feel like it would look nicer to run the branches into a reverse switch and then exec the dispatcher only once

Basically it would cap the number of nodes at 2 (switch and then 1 dispatcher), instead of however many different actions you are going to dispatch

[foggy escarp]

This seems clean to me, you're saying you want to combine multiple of these inputs?

[jagged stone]

It looks ok now, but imagine you have like 5 or 6 different actions, but it starts to look a bit messy....(example 1 click, 2 clicks, 3 clicks, short hold, long hold etc...)

Calling the dispatcher only once would be nicer

[foggy escarp]

Ahh, OK.
Well it's technically only calling it once here, there's just more than one way to do it.
But the only other way I could think of is to instead of using branches you use selectors and use the comparative math nodes to select a enum.

[jagged stone]

Image if you could flip this switch around

[foggy escarp]

Okay

Instead of using a branch to choose your enum, just set the enum. Then use a enum switch

Swap out the dispatch for the set enum node

The dispatch can be done last with the enum as input

[jagged stone]

But this is done from the event graph, so i don't have any local variables to set the enum to

[foggy escarp]

Use a function

I have a scene capture and when I change it to orthographic view it hides the sky, anyone knows why?

How do i make sure my character 🔵 stays at a minimum distance from another 🟣 ?
I have a character 🔵 . Move it to the small blue dot location, first arrow. Check its distance from purple, orange line.
Check if orange line is smaller than the minimum distance, green arrow. It is not.
How do i know how much more distance i need to add so to make sure it is higher than the minimum distance (green arrow) ?

[harsh coral]

Just a quick repost here from cinematics...
I have a complicated setup where I need to render dozens of layers of the same blueprint.
I set up a master sequence, added in instanced level sequences and added the blueprint as a separate track in the Master sequence.
The idea is then, that I can animate various booleans on the master sequencer track and render out the whole master sequence as one file, instead of having to manually change the booleans, add to movie render queue, render, change booleans, add to movie render queue etc...

I exposed the booleans inside the blueprint to cinematics and it works if I scrub the timeline or play in editor.
But when I render via render queue, the animated booleans get ignored.

The booleans in the blueprint simply switch out the material instance that is used in the construction script.
I COULD animate the material switch directly inside the master sequencer track, but it doesn´t work, since the material instances rely on some stuff in the construction script.

Its a bought asset and the dev couldn´t help me with this so far.

Any ideas how I could make it work?

Please ping if you have an idea, as I´ll be afk for a while...:)

[low marlin]

how do i get the nth item in an array

[sly spade]

hey, does anyone know how to get socket rotation(pitch) in 0-360 degrees?

[tawdry lava]

Use https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Utilities/Array/Get_acopy/ or https://docs.unrealengine.com/5.0/en-US/BlueprintAPI/Utilities/Array/Get_aref/

[low marlin]

does it work in an array of integers

[tawdry lava]

It should work for all arrays 🤷‍♂️

[tall oxide]

I have widget that comes up when door is locked. how can i make it stop coming everytime (it stacks up). So basically once for every 10 secs if interacted?

[paper galleon]

Did you forget to remove from parent?

[tall oxide]

no

it comes to the screen and then fades away after 2 sec

but if door is interacted again it will create new one

so how could i make it stop coming on every interaction

i dont want multiple of those same widgets on the screen

[paper galleon]

Like you have to specifically call remove from parent on that widget.

[sly forge]

I'd say add a "is in viewport" branch or something like that before Creating/adding it to view port

[paper galleon]

Do you have a reference to it?

[tall oxide]

need to try this one

[sly forge]

And when animation finishes remove it from parent

[tall oxide]

yup thats done

need to setup the is in viewport now

not sure how to do it properly tho

[low marlin]

can i set an array to another array

[spark steppe]

no

but you can put an array in a struct and make an array of that struct

[low marlin]

how

[tall oxide]

how can i stop widget from creating when condition is true

[elder crater]

hey everyone idk where this question belongs but is there any way to have some code get called when world partition finishes loading up some specific cells?

[tall oxide]

what am i doing wrong here

[sly forge]

Put the branch before create widget

Don't check Newly created widget

[tall oxide]

?

works but error occurs still

[sly forge]

Make a reference when you make the widget, then check that reference if in view port

[tall oxide]

how do i make the reference

[gentle urchin]

Right click the return value

Promote to variable

[sly spade]

use an isvalid check

[gritty elm]

what is best way to hide these corners in large landscape?

Because I have flying camera, so it should looks good.

[tall oxide]

it is a mess now

😂

[silk cosmos]

You could try the water system and create an island out of it. Other than that, no not really. You have to use design tricks to hide that. Like distant mountains that you cant fly to that cover it up

[silk cosmos]

Let's start over. On create widget off the return value, right click create variable, then drag off the variable and do add to viewport. Before the create widget use that variable and drag off and do is in viewport -> branch -> false -> create widget.

[astral epoch]

I believe the way that Cities Skylines does it is a thick fog-border and preventing the camera from getting that close?

[low marlin]

what do i put here

whats event

[astral epoch]

The boxes coming off of custom-events.

[silk cosmos]

The event you want to be called when you call on clicked

[astral epoch]

There's a deeper explanation but that's the gist of it.

[low marlin]

oh

how uh

how do i use the click event in a widget on the level blueprint

[astral epoch]

On a level blueprint? Is that even possible?

[tall oxide]

idk why its so hard to undestand english

works again but what i do from the true branch

[astral epoch]

You're uh.... using a boolean from something created after the branch that checks said boolean?

[silk cosmos]

You'll want to get a reference to the widget in question and then use bind on clicked and then assing the event you want to be called

[silk cosmos]

Drag off event and look for create custom event or something along those lines

[astral epoch]

Okay quick explanation.
That red box, you drag from another event onto that. When you do an "OnClick" it will trigger that custom event in question.

[silk cosmos]

Then when you want that event to be called in your widget when you click the button call on click

[low marlin]

like this?

[astral epoch]

Yes.

[astral epoch]

That "menubuttonclick" event will trigger when you click.

[low marlin]

it doesnt work tho

[astral epoch]

Because there's no execute pin going into it.

That bind is never happening.

[low marlin]

button no worky

[low marlin]

?

oooh

[astral epoch]

After your "add to viewport" node you want to drag the white line into the Bind node.

[low marlin]

lets fucking go it works yayyyyyyy

thank you

[astral epoch]

No problem

[tall oxide]

i can still stack the widgets

[tall oxide]

this worked but gave the error accessed none bc of the true pin i think

[gentle urchin]

You should create it once

Use a getter (create a get MyWidget function)

Where you check if the variable is valid, if not, create it, set it, return it

[candid sentinel]

can component tags NOT be replicated? im trying to set them through RPCs and for some reason things arent working

[stable dove]

probably a dumb question but i cant figure it out, trying to setup a widget that has a text box to display the total score of two dice how can i get a variable from an actor bp that is the dice object to use inside of the widget bp?

like what needs to go in the object pin to make this work

[tall oxide]

idk man i get so much infomation now that i dont know what im even doing now

[paper galleon]

Aaand you're back to the beginning again.

[tall oxide]

😂

[paper galleon]

The issue is that you're not storing a reference to the widget.

The pin that comes off the create widget, drag it and right click and select create variable

[gentle urchin]

Make a function for it !

To safely create and get the reference

No bogus

No early calls

[gentle urchin]

References to the objects

[tall oxide]

promote to varibale

[paper galleon]

Yeah this.

Bad memory

Sometimes

[tall oxide]

oh yeah its okay

what do i do with it

[paper galleon]

Before the create widget node. Get that variable. And check if it's valid

Then after you create widget, set that variable to the pin coming off the create widget node.

Then add that variable to viewport.

In the is valid check, you drag off the false

Only issue is that I don't know what events cause the widget to be removed

I need more info on that

[tall oxide]

its animated widget

pops up, stays 2 sec and fade away

[gentle urchin]

If its a fire and forget type of widget

[paper galleon]

Hmm. Can you bind events to the animation? You need to remove the widget from viewport when the animation fades away

[gentle urchin]

It should handle its own lifetime

[paper galleon]

True.

[tall oxide]

yup its deleted after animation

so the variable comes before create widget

[paper galleon]

Like there's an event that specifically deletes it. Or just because it fades you assume it's deleted.

[tall oxide]

remove from parent

[paper galleon]

Okay. That's fine then.

Send your code for a review then test

[tall oxide]

its not right yet

trying to understand the intrusctions

[low marlin]

does anyone know how to pad a number like 4 to 04

[tall oxide]

is here all the nodes i need

[paper galleon]

You didn't do the is valid check before.

Get new var3 and do is valid on it

But seriously, at this point, I'd say watch a few more tutorials. You're lacking some fundamental knowledge

[tall oxide]

u know some good videos at this topic

to get this work atleast

[paper galleon]

What you need is general blueprint knowledge. I recommend Ryan Laley on YouTube.

[paper galleon]

Just search unreal engine widgets on YouTube

[tall oxide]

okay

[gritty elm]

I have big landscape. and I have fly over camera. How to hide landscape corners?

so it will looks like seamless landscape

[paper galleon]

Didn't someone answer you earlier?

[gritty elm]

reposted again. Water didn't fixed it.

As you can see there is water too.

so what solution will be?

[paper galleon]

I don't know

[tawdry surge]

Doesn't look like the water is covering your landscape at all. It's just behind it

[stable dove]

How do i stop the default camera and default pawn from spawning

[gentle urchin]

Override the spawn(OnStartPlayer or something along those lines)event in the gamemode

[paper galleon]

Unless you have a custom character/pawn, you need something to move around in the editor.

[gentle urchin]

Which will make the spectator spawn instead

[stable dove]

its only really the default pawn thats causing issues

[gentle urchin]

Make your custom pawn

Solves all issues

[stable dove]

wdym "make your custom pawn"

[gentle urchin]

Make a new actor if type pawn

Set it as default pawn class in the gamemode

[cobalt bluff]

Hey everyone, is there a way to hide blueprints in a project you shared with people?

[gentle urchin]

Add whatever functionality you want to it

[stable dove]

i dont want any actors in this scene tho

[gentle urchin]

Are you really sharing if you're hiding

[stable dove]

level*

[gentle urchin]

You must

Its not a choise

[paper galleon]

Nope.

[cobalt bluff]

I mean when I send to someone I want them to be able to use it but they shouldn't acces the source code

[paper galleon]

Nope.

[stable dove]

well then can i atleast move the default pawn spawn point to under the map

[paper galleon]

It's not really compiled the way C++ is.

[gentle urchin]

Why would you not have a pawn anyways ?

A pawn is just a possessable actor

Doesnt need to do anything

Can simply provide a camera if desired

[stable dove]

all i want to use this level for is to drop two dices on a platform and read there score then go back to the default level

[gentle urchin]

So you still need a pawn ^ :)

[stable dove]

but maybe i should just place the platform where im dropping the dices miles away in the same level and just switch to the camera above the platform for the dice rolling part

[gentle urchin]

Doesnt have to be a character

How troublesome is that

[paper galleon]

There's no game without a player. You still need a pawn. Just spawn one and forget about it

[gentle urchin]

When you can just make a pawn

Have it do nothing

And it just works 🤷‍♂️

[paper galleon]

Doesn't even need a mesh or anything.

Just an object instance of the pawn

[last abyss]

or just place a camera in the world use set view target with blend in the level blueprint, no need for a pawn 🤷‍♂️

[stable dove]

Added a pawn but its still spawning the default one

[gentle urchin]

Swap the default pawn in the gamemode

[gentle urchin]

Afaik you must have a pawn either way

Wheter you're looking at it or not is a different case

[last abyss]

I mean pawns are just there for possession right? Isn't the camera manager on the controller

[paper galleon]

Seriously adding a pawn is a lot less trouble than trying to figure something out.

[gentle urchin]

I dont see how a workaround is any less work tbh

[paper galleon]

He'd have to override the game mode to prevent the pawn from spawning.
Somehow, I doubt he can pull that off properly, no offense please

[gentle urchin]

It wouldn't stop the pawn from spawning

It would fallback to spectator

[paper galleon]

Exactly

And a spectator is a pawn

[gentle urchin]

Yepp

All year long

The problem here isnt the pawn tbf

[last abyss]

So even if u disable pawn spawning, it would still pawn a spawn?

[paper galleon]

Yes a spectator pawn has a camera and no body. But it's still a pawn

[gentle urchin]

How would you disable it...

[paper galleon]

Pawn a spawn. Nice one

[last abyss]

By making the selection none in the gamemode override? I don't really know the step to step of the world's creation but I assumed since the camera manager is in the controller you wouldn't neccessarily need a pawn, unless the controller requires a pawn?

[gentle urchin]

It still goes for the spectator spawn

[stable dove]

turns out i just had to set default pawn class to none

[gentle urchin]

Watch spectator pawn spawn *^

[paper galleon]

Lol

[gentle urchin]

Free roam, flying

[paper galleon]

Damn. When you have a hammer.....

[stable dove]

nope its all working fine now

[gentle urchin]

Check your world outliner

Ill eat some salty chips if theres no spectator pawn there

[paper galleon]

Bruh, the point is that it's nearly impossible for you not to have some sort of pawn in your world

[last abyss]

[gentle urchin]

Salty chips inc

Unless floor is a pawn?🤔😂

[paper galleon]

Damn they changed stuff up in UE5

[gentle urchin]

It appears so

[last abyss]

just code it to move on command, basically a pawn

[gentle urchin]

Just code it to accept input

Then move

Life without a pawn is not much life jk

[last abyss]

well in ue4.27 there's also no pawn if u select none

[paper galleon]

Huh... I'd like to apologize.

[obtuse herald]

or do it yourself

creating portals is an adventure

[slate sorrel]

Don't know how right now

I tried watching tutorials and I couldn't find anything for third-person characters

[obtuse herald]

https://michaeljcole.github.io/wiki.unrealengine.com/Simple_Portals/ this is a pretty nice guide to start with

[hallow gate]

Quick math question, is there any way to jump two numbers towards 0 by a certain amount if the current number isn't zero?

So say X = 110 and Y=-155, when I trigger the button I check to make sure they aren't 0, easy, but then how do I make them detect that X is > 0 and Y is < 0 without a million billion branches?

I definitely CAN do it with branches but I SWEAR there's a friendlier way to do it and I haven't found it

[dapper marsh]

Maybe substract a fraction of said numbers

[obtuse herald]

2 branches

[hallow gate]

@obtuse herald I have to cover the possibility of X being > or <0 and adjust accordingly, and Y being > or < 0 and adjust accordingly also

[obtuse herald]

one to check that it is not 0, and one to find out if its positive or negative

ohh

yeah ok

[hallow gate]

Yeah, you see my issue

Haha

[hallow gate]

Can you explain in more detail?

[dapper marsh]

yes sorry, uuh

[hallow gate]

Like, this FEELS like something that would exist and be covered, and be called something like Normalise, but I can't find it

(For reference I'm zooming out on a map and making sure the map doesn't leave the boundary of the scale box by repositioning it by 55 pixels at a time)

[dapper marsh]

okay I might have misunderstood what you wanted to do

[low marlin]

does anyone know how to made many scene captures (2d)

[obtuse herald]

actually

there is a Compare Int macro

[low marlin]

and then use a target on some actors?

[hallow gate]

Hmm

Let me look at that for a bit

One issue, I'd still need to repeat it a lot

[astral epoch]

Okay good or bad idea:
I want to have my player controlling a group but when the group gets into combat they take control of a hero character.
This will naturally need two very different control schemes.
I'm thinking of using bind events to "switch" between these two control schemes. Good or bad?

[obtuse herald]

if you double click on the macro you'll see that it's just 2 branches after all, but it looks cleaner

[hallow gate]

Because if X > 0 but Y is < 0 then I'll have to repeat Y for every output of X

[low marlin]

that sounds fun

[hallow gate]

Not the WORST compared to the branch method but still a pain

[warm forge]

I need some help figuring out how to get the world coordinate given an Input Touch. When I touch the screen, the Input Touch give me an X and Y with the origin at the top left of the screen and the it increase to the right on X and down for Y. Any idea how to do that without using the Player Controller.

[astral epoch]

I've seen a small few other games do it before, ones I'm sort of making mine a spiritual successor of.
Issue is they use a custom in-house engine, I know Unreal is a bit twitchy about users trying to break the mould.

[low marlin]

huh

[astral epoch]

nvm

[hallow gate]

Hmmm

I've had an idea, one sec

I'll report back how it goes

[dapper marsh]

An issue I've been trying to wrap my head around for a while now: I have a player, mostly the default FPSCharacter. My goal is to make it so it can trigger the hit event if hit by BP_EnemyProjectiles. What should I set the collision types at each actor so that happens?

(that hit event will decrease the health of the player)

[desert juniper]

just check if the other actor is of class BP_EnemyProjectiles (Cast)

[astral epoch]

Have the projectile use an onCollision event that calls something on the "other actor". Do this by casting or you can use an interface.

Basically the projectile should be telling whatever it touches to apply damage to itself.

[obtuse herald]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Canvas/Deproject/ I guess?

[dapper marsh]

yes, I do that, the problem is not the how, are the collision values themselves, I cannot make the player "collideable" without making them unable to move

[astral epoch]

Okay that's odd.

Show me how your player is set up

[dapper marsh]

https://gyazo.com/17984acb10ff33571298b8b5300e48d9

[low marlin]

does anyone know how to make a bunch of textures and apply it to actors?

[spice imp]

Does anybody know why I can't seem to add a second material slot to a DynamicMeshComponent? The Geometry Scripting stuff has all kinds of support for manipulating a mesh's material ids, so.... I don't know why it doesn't want more than one material on a mesh. What am I missing?

[astral epoch]

Have you been messing with the character's collision settings itself?

It should work out of the box.

[dapper marsh]

well it does not

projectiles go right trough

[astral epoch]

You have it set to ignore pawns.

What is your projectile?

Like its parent class?

[dapper marsh]

collision setup you mean?

ah

Actor

[astral epoch]

Okay that... should be fine?

Do a quick test for me. In the projectile, add an on collision event and just have it print out text.

Then shoot at a character. See if that comes up.

[dapper marsh]

on it

hold on, gotta change one thing, I was using a proxy collider, hold on

okay these are the collision settings for the player
https://gyazo.com/f4053569d4764a02e2fe9d73ac459ce5

and these for the projectile
https://gyazo.com/ecd36969b3638fad225f1209bfb71940

They are wrong 100% sure

[astral epoch]

They look correct?

[dapper marsh]

well the projectile does not print anything

[astral epoch]

Its definitely shooting right?

[dapper marsh]

yes

[hallow gate]

This just HAS to have an easier way to do this haha @dapper marsh @obtuse herald

But this "functions"

[astral epoch]

Put a print-string on the beginplay for the bullet?

[hallow gate]

Albeit it's spaghetti

[astral epoch]

good lord what am I looking at?

[hallow gate]

Maybe you'll have an idea to do it easier if you see what I'm trying to do
