blueprint

[hollow cove]

would the 2d input here be the starting location

or the center of the thing

[marble tusk]

That'd be the position at 0

[hollow cove]

ah thanks

[marble tusk]

Also, does it need to be whole numbers? That's why I added the signs at the end. That way X and Y can only be 1, 0, or -1

removing that would make it a circle where it couldn't reach X 1, Y -1 for example

[hollow cove]

so in my test
0 is X=0.000 Y=1.000
0.125 is X=-0.707 Y=0.707
0.25 is X=-1.000 Y=0.000

i would have expected 0.125 to be -0.5, 0.5

[dawn gazelle]

MapRange node?

Oh nevermind, I see now.

[marble tusk]

not -1,1 like the image you posted?

[hollow cove]

it would sort of circle around linearly

[marble tusk]

Let's say you're drawing a shape with it from 0-1, what is the shape it should make? A square, a circle or well I guess a square but rotated 45 degrees

[hollow cove]

i think it would be the 3rd one

diamond

[marble tusk]

I'm also just now realizing that X and Y should be switched because Unreal is left handed

[marble tusk]

Which is why X is negative there when I was thinking it would be positive

[trim matrix]

What was the name of the node that gave the GAME time the actor was alive for? (I need bigger accuracy than seconds)

[hollow cove]

wait no, it would be the first one

god this is hurting my brain

yeah definitely square

its for wind direction

i want to be able to move the wind around in a circle rather than having it suddenly switch directions which can look odd

so i would never want anything to be 0.5, 0.5

[marble tusk]

I mean, this basically outputs a directional 2D vector where the length of the 2D vector is 1. It would draw a circle in the examples I drew above. That's probably what you'd want for wind direction I'd imagine

If it's a square where at 0.125 outputs 1,1 then the length of the vector would be larger than 1 and depending on how it's used could cause unintentional scaling problems. Like the wind could be stronger when it's at the corners like that

[near shard]

does anybody know a way to make a custom volume that uses points to draw its area? Im trying to use it as a top down 2d navmesh

Kinda like this where I can make custom geometry

[dawn gazelle]

Use the Radian function type for COS and SIN

[trim matrix]

bump

[hollow cove]

get game time since creation

[hollow cove]

got it working, thanks for all your help 🙏

[flat coral]

How do you go from a world-space transform to a local-space location again?

sorry the coffee hasn't hit yet this morning

Wait shit I don't even need local space I need it relative to a specific component... dang I'm gonna have to do math arent I

[hollow cove]

probably a better way to do this, but you can just get both in world space and subtract from each other

[modern radish]

is Set Game Paused the ONLY way to really pause a game? I'm experiencing that some stuff tick even with game paused

This works and my screen fades.. but some logic on my Controller BP continues to run and prints normally

[neon burrow]

Controller BP ? is it input?

[flat coral]

I think there's a setting in events to get them while paused or not

[modern radish]

Yeah my player controller

[neon burrow]

pretty sure there is like ( disable player input )

or something

this is mine, but might not help you

i don't pause my game tho

[flat coral]

If it's an input event that's triggering, check out this setting on the event itself "execute when paused"

[lunar sleet]

Old input system tsk tsk

[flat coral]

There's a new input system!?

I'm still on 5.1

[lunar sleet]

#enhanced-input-system

Been around since 5 iirc

[neon burrow]

its from 5.0 pretty sure

[modern radish]

thanks for the answers, that doesn't really solve it for me. If I pause my game after some Custom Event was triggered on my Player Controller, it seems that goes on

[flat coral]

What do you mean it "goes on"?

[modern radish]

things on my logic are timed, and they still print even if I pause, for example

[flat coral]

Pausing the game isn't like hitting a breakpoint in the code, you stop getting tick events and input events (if that option is unchecked) but the code continues to execute if it already is

Ahhh you have timers? Or delays?

[modern radish]

delays, yes

[neon burrow]

maybe make a branch or something to see if game is paused

[frosty heron]

Show

[modern radish]

I see yeah, it makes sense

[modern radish]

it's a huge network lol, I can try

[neon burrow]

having a bool and a branch might fix it, but its most likely not the way to go

[frosty heron]

Just show the delay bit
Why is it recursive??

[modern radish]

it's not recursive

let me try and explain it a bit better..

[frosty heron]

Pausing the game not gonna stop your timer, it just stop calling tick on function that is untick on "tick on pause"

This is why normally pausing is a shit show all together

[modern radish]

Player Controller has a function in it called PostLevelLoad.. that is called by the level when it loads, from the level BP.. this part of the graph in the player controller sets up lots of things for the game such as UI, prepare some geometry etc.. this also goes and runs for about 5 seconds, then it prints Play Allowed

yeah that makes sense now that you explain it

if I pause after this part, later in the game, works great

thats why I was asking if there's some sort of hard pause, freeze everything

[frosty heron]

. If u halt the game thread then it's frozen and probably can't be un*ucked

[modern radish]

yeah I thought so too, lol

"This is why normally pausing is a shit show all together"
Didn't know this

[frosty heron]

I personally haven't encounter problem yet with pausing but the vet says so. So 🤷‍♂️

[flat coral]

Pausing is not an easy problem! Baldur's Gate 3 is probably going to be GOTY and it has no pause function. This is something real studios and experts struggle with at times.

We're actually quite fortunate that Unreal just hands us a physics system and particle system that can be paused. It's not uncommon to see a game where like it pauses, but fire continues to be animated while it's paused for example.

[flat coral]

I think in your case just don't let them pause during level load. Hell, from a player perspective, if "Play Allowed" isn't true yet, then the game IS paused

[modern radish]

Thanks for the insight, yea never thought about this

that's is an awesome suggestion mate, solved! lol

thanks so much

[golden gull]

how do I make it so that in game you can see the mouse cursor? I am setting the set show mouse cursor on play in my player controller blueprint but it doesn't seem to work

nevermind I forgot to set it as my player controller in the gamemode ❤️

[trim matrix]

i thought for a second you wrote all of that within a single message

[runic pagoda]

I'm trying to send data back to a gameplay ability from an actor blueprint (the rest of the code is in the GA, but it needs the 'target data' intput) but I'm not sure how the chain of cast object references will work. Any advice?

[lunar sleet]

Ask #gameplay-ability-system how to get a ref to the gameplay ability

[runic pagoda]

I've tried there a couple times but noone seemed to know. I can try again later and see if a third shift of people may have an answer though

[lunar sleet]

I honestly dunno. To cast you need to get the ref somehow, usually it’s through an interaction or get actor of class/get widgets of class/get user widget. But no clue how one would get a ref to an actual GA

[dawn gazelle]

You don't want to communicate directly with gameplay abilities like this. They're meant to be mostly self contained and they pull data from other sources, listen for events, and use tasks that can wait for data.

[fiery ridge]

Is there something like "switch on boolean"? I don't want to make a bunch of Branch nodes

[trim matrix]

select

[fiery ridge]

But select only returns true or false. I need to execute specific nodes/pins based on which index is true/false

something like Switch on Int dfoes

[trim matrix]

a bool can only have 2 states, so you use branches for that

[fiery ridge]

Yeah I'm trying to avoid making a bunch of branch nodes

[trim matrix]

it would be helpful if you showed what u actually are trying to do

[fiery ridge]

Like execute different logic based on the index options

This only returns one value

(for example, if option 2 is true, then execute this logic)

this does the job but it's integer

[trim matrix]

you normally would do this sort of thing with branches

[dawn gazelle]

You can use ANDs or ORs in combination with a Sequence and Branches.

[fiery ridge]

yes thats true, but im trying to see if there's a more efficient/better way of doing it

[dawn gazelle]

Alternatives would be to use a BitMask integer or a byte array and convert that into an enum of some kind to use on a switch statement.

[fiery ridge]

i was thinking of turning bools into integer and then switch on int

because making a bunch of Branch nodes seems to me like a caveman asking the engine, is this true or not a bunch of times lol

[trim matrix]

i think that converting them to ints would be even messier

[fiery ridge]

im listening

[trim matrix]

but what do i know 🙆‍♂️

[fiery ridge]

well you tried, thanks ❤️

[dawn gazelle]

Here's what you could end up with... The bits to byte node is from a free plugin.

Just isn't very clear what is happening.

[trim matrix]

wow there's a node like that?

crazy

[fiery ridge]

this is very clear, i think that's exactly what im looking for

thank you ❤️

[dawn gazelle]

Bits to Byte is from Low Entry Standard Extended plugin on the marketplace.

[trim matrix]

aha so there isn't 🙂

[dawn gazelle]

Not really... The bits could be fed into the byte in whatever order, and the enumerator description won't necessarily match up to the inputs. The higher up you go, the more complex it is to describe as well.

[trim matrix]

if the user will connect it nicely, it'll look just fine

[fiery ridge]

If i understand correctly, for example, your bool bit 4 is true, gets converted to byte and gets fed into the Enum selection. what's the issue here

[dawn gazelle]

If you have bool bit 4 true, and bool bit 1 true, and bool bit 2 true, then you have to describe that all 3 of those things are true.

[fiery ridge]

Ahh in my case so far, I think only one bool will be true at a time

[dawn gazelle]

Then you probably want to use an enumerator for the value.

Rather than a bool.

Bool: on or off.
Enumerator: one of 255 human readable values.

[fiery ridge]

ill try both out and see what happens

[flat coral]

How do you change the distance that decals disappear at? It seems to be based on the size but it's way too aggressive, this second set of bullet impacts aren't even visible a few feet away

[trim matrix]

fade screen size

[flat coral]

Hell yeah, thank you!

[surreal juniper]

stupid question but i need to change if something gets added or subtracted based on a value. my only issue is that I get branches work but is tehre something easier than just copying everything you have with a branch

like, theres a bunch of shit that this is connected to and i dont wanna have to clone it and branch just for that clamp

[elfin hazel]

Perhaps you can make a function that does the thing, and all you need is to provide the inputs.

[dull kraken]

Hello, Im getting a weird problem. I have a parent bp and it has some functions and variables. When I click and make a child of it the child doesnt inherit the functions and variables. I have checked and they are set to public

[elfin hazel]

Is this enabled?

[surreal juniper]

@elfin hazel hey thanks but i got it theres a thing called select float

[dull kraken]

thanks, my variables are showing now, anyway to replicate the function aswell?

[elfin hazel]

It'll probably be in that override list that you can see beside the Functions header

Functions aren't overriden by default.

[dull kraken]

my function has access specifier set as public. other then that im not sure what other override list you could be on about

[dull kraken]

never mind, haha I override the function on my child and selected the func that way. yes just figured out haha

[visual stump]

I am trying to replicate Outer Wilds 1st person movement in Unreal. I was trying to follow this tutorial (https://www.youtube.com/watch?v=bEWgGnq5h7c&t=2225s) but when I try to do it in 1st person I have a lot of issues and it uses movement input to simpulate gravity, when i actually want to use forces. I don't know what I should learn or what to do to get that effect. Any help is welcome

[outer forge]

I can't access many of the timer functions inside my UObject, why is that exactly? I only have the "by function name" variants

[lunar sleet]

Wdym it literally says set timer by event there

[dawn gazelle]

UObjects don't have a world context which is where timers are handled.

[lunar sleet]

Ah, bp limitations of cpp stuff 😀

[outer forge]

Oh my, so I can't use them inside UObject at all, or do I just need a reference to a world context?

[dawn gazelle]

You might be able to if you give the object a world context.

[runic pagoda]

Well the gameplay ability has triggered a set of actions on an actor blueprint, which results in a 'target data' result which I then need to get back to the GameplayAbility for the next parts.
'Using tasks that can wait for data' sounds like maybe it's what I'm after, but I haven't found any examples of that in action for me to learn from / copy

[outer forge]

I'll give it some tests, thank you 😄

[dawn gazelle]

So yeah, found in one of my projects I had given a UObject a world context and it allows me to create timers in it.

All that's needed in the UObject definition is:
.h

    virtual UWorld* GetWorld() const override;

.cpp

UWorld* UYourOjbectClassHere::GetWorld() const
{
    //Return null if the called from the CDO, or if the outer is being destroyed
    if (!HasAnyFlags(RF_ClassDefaultObject) && !GetOuter()->HasAnyFlags(RF_BeginDestroyed) && !GetOuter()->IsUnreachable())
    {
        //Try to get the world from the owning actor if we have one
        AActor* Outer = GetTypedOuter<AActor>();
        if (Outer != nullptr)
        {
            return Outer->GetWorld();
        }
    }
    //Else return null - the latent action will fail to initialize
    return nullptr;
}

This assumes that the outer that is provided when the object is contstructed has a world context of course.

[outer forge]

Wow, that's perfect, thanks a lot!! 😄

[lunar sleet]

What is the use case for using this instead of just an actor for example?

[dawn gazelle]

Some things don't need to exist in the world and have the extra baggage of being an actor.

[lunar sleet]

Ok, but if you give it a world context doesn’t that mean it’s in the world ? Sry, brain is weak 😅

[dawn gazelle]

No, it's not something that necessarily exists in the world, you're just allowing it to grab a context of a world that exists. You can actually have more than one world existing at a time, and technically the UObject doesn't get spawned in any of them, it just exists in memory and you can give it whatever world context you want, even at run time by changing what world is returned by GetWorld().

[lunar sleet]

Oh, I didn’t know you could do that

[mild tangle]

anyone know why im unable to use get player character in an actors construction script, I am attempting to reference the player character

[dawn gazelle]

Doesn't make a lot of sense to grab in the construction script as the construction script can happen before runtime. I don't think that stops you from calling other functions from the construction script that may call get player character though <_<

[elfin hazel]

Get Player Character refers to the character that a controller is controlling, does it not? And Player Controllers does not necessarily exist in construction. Or is possessing one.

[trim matrix]

What would be the "sanest" way of trimming silence from the beginning of a recording? (BPs only 🙂 )

or skipping it in the media player at least

[mild tangle]

the actor spawns during runtime, never before

[trim matrix]

get player character works only once the game starts

[dawn gazelle]

That's not entirely true. When you place an actor in a level it is spawning an instance in the editor.

[mild tangle]

i will not be doing this

[dawn gazelle]

And its construction script runs at that point.

[mild tangle]

how can i get around this

[dawn gazelle]

You can call another function in the construction script which then does whatever call you want with Get Player Character.

[mild tangle]

sounds good thanks

[lunar sleet]

Possession happens after begin play usually

[dawn gazelle]

Fairly certain this isn't something you can do in Unreal blueprints. Clean up your audio using an external tool, use the built in wave form editor? (I'm not familiar with this myself but it's apparently a thing), or you'd have to find some means of modifying it during import (C++) or having some functionality that checks where the audio begins before playing it so you can play it at the right time (C++)

[trim matrix]

well you see, the audio is something that will get recorded at runtime 🙂

there's no way for me to to edit it beforehand

[lunar sleet]

Bp can only take you so far

[trim matrix]

how would i go about transfering assets from a newer engine version to an older one?

from 5.2 to 5.1.1

[dense jacinth]

Does anyone here know how consistent and good feeling dashes / bounce pads are implemented in games like celeste?

Right now I currently just set the player's speed to a certain value for some time and that definitely covers consistency

but something about it feels off, and I can't tell what

[lunar sleet]

You can’t usually go backwards

[dense jacinth]

also, this implementation is very poor for like sideways bounce pads because it'll launch the character directly horizontally for some time before dropping
but I can't use something like launch character because it just feels extemely inconsistent

[trim matrix]

is it possible to edit the data version or whatever?

[trim matrix]

@toxic jay smart person, what do you make of this?

i can see this thingy within the raw uasset file, dunno if i can just edit it tho

[lofty rapids]

it's normal for things to be compatible with lower versions, but not higher versions as new stuff was added and would most likely break it anyway

[trim matrix]

can sb send me a random 5.1.1 bp .uasset file pls?

i need to test things

it can be an empty actor

[pulsar vigil]

Hey guys noob question is this weird to branch before a sequence in bp ? is it some sort of super bad behaviour ?

[trim matrix]

okay, managed to force the editor into reading the file from the newer version

now it crashes 😁

the bytes are unaligned and stuff

[lofty rapids]

it doesn't sound too weird, if you need the branch before the sequence it's basically the same as if you didn't have a sequence

[trim matrix]

it even crashes less now

[pulsar vigil]

Ok thx i dont know its sound like a bad idea for me lol

[sharp pasture]

Did you ever get this working? I'm having the same issue even after compiling the engine from source. The process fails when SymGetModuleInfo64 returns false, with the error: The specified module could not be found.
Here's the full error from the Unreal Engine Log:

[pulsar vigil]

Guys somebody know what this thing do ? Cause im trying to use it to not have to create a bolean that assign a value when pressed but that doesnt seem to be is function

[remote meteor]

When any of those event on this node is executed, the action value will be updated, in this case, whether the input is over the trigger threshold.

To access this value, you also can use IA_R value in the right click menu.

[pulsar vigil]

thx ! so i did understand a bit but i was transfering this value via an event dispatcher to my widget to use it to change a element scale and it dont work is that normal ? i did use event dispatcher just before for other thing and it work fine so i massuming since i did the same process its not were it bug

also no print work either to debug it so it realy seem like it the action value that doesnt work as intended in my case

[lunar mulch]

What would be a good replacement for a Timeline node? I'm trying to slowly fade in a post process effect, but im working inside a Actor Component so i cant use any timeline nodes.

[edgy ingot]

Tick and delta time

[grizzled cave]

tick and delta time not be that good for performance
but you can just do timeline in the character and access that somehow 🤷‍♂️

[thin panther]

tick and delta time are absolutely fine for performance

[grizzled cave]

people always say tick is bad

[thin panther]

and they're wrong

[dawn gazelle]

And those people don't know what they're talking about

[lunar mulch]

So which one is it 😛

[thin panther]

tick can be bad, and it can be misused, but that is no different to any other tool at your disposal

[lunar mulch]

Maybe this can help determine wether it should be on tick. It's basically tracking stamina, and when stamina reaches a certain point it will start fading in a post process effect

[frosty heron]

Pretty sure timeline have more overhead than tick and delta time 🤷‍♂️

By people always say tick is bad you probably mean youtube people

You can read pinned post in this channel that demystify common blueprint bs, revolving around tick and cast

[dawn gazelle]

If it's something that needs to happen every frame so that it appears smooth, Tick is what does it - anything else is adding extra steps and checks which still run on tick, and it might not even result in a smooth effect as it's not matching with the frame rate.

A timeline is ticking too just in a different package - it binds to and listens for a ticking event to then run its update output when that tick event is called, and then unbinds itself when it has reached the end of its timeline but that's something it has to check each frame, so it's actually slightly less performant than just using tick constantly, but it's also something that can be easily turned on and off so there is a good trade off. Tick can be toggled too!

A delay? It binds to that same ticking event, incrementing an internal value every tick based on how long the frame is and checking if the value >= the desired delay amount and if so, unbinds itself and calls its output.

A timer? It binds to that same ticking event, and works just like a delay, but it also gives you a handle that allows you to pause, cancel and even loop it until a desired point in the future.

The trouble with delays and timers is that there's no guarantee of when they will actually trigger as they're based on a certain amount of time, which can mean it can happen outside of when frames are actually happening. Eg. Using a looping timer set to 0.016 to pretend to be waiting for the next frame only works if your framerate is a constant 60FPS. If you're running 120 FPS then that timer is executing at half the frame rate.

Where you run into problems with tick is if you're using it for things that don't need to happen every single frame including if you have hundreds of actors ticking that don't need to be ticking. Changing a value over time on tick is nothing in the grand scheme of things, so long as there isn't hundreds of math nodes and function calls involved trying to get to that value.

[dawn gazelle]

Yep

thanks I was afraid of ''overkilling it''

[lunar mulch]

Thank you, this taught me alot!

[fiery tiger]

Does anyone have an idea how I can utilize my player camera pitch to affect how far you jump? The simple result I'm looking for is if the player looks up (Y rotation between 0-90) when performing or during a jump, they will actually jump a further distance. 90 having the strongest affect.

I'm very new to blueprints and not a programmer so please be gentle. Everything I've done so far has been through tutorials. Any help is greatly appreciated!

[frosty heron]

Use map range clamped

The in value is your Y rotation

Input A is 0 , 90
B is minimum jump velocity, maximum jump velocity

You can use the return value to set your jump velocity. Then you can commit the jump()

[unborn mauve]

Getting this exception error on startup. It occurs whenever a camera animation sequence is referenced in code:

Ensure condition failed: Registry [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Engine\Private\Elements\Framework\EngineElementsLibrary.cpp] [Line: 33] 
Typed element was requested for '/Game/Cutscenes/CAS_Stumble.CAS_Stumble:MovieScene_0.CineCameraActor_0' before the registry was available! This usually means that NewObject was used instead of CreateDefaultSubobject during CDO construction.```
I don't understand how this can be an issue if it I'm not using the sequence until runtime, but the exception is thrown on startup of the project. It works fine in editor but as soon as I try to open the project again, it won't load because of the exception. So long as the sequence is present in any node that is executed in any bp, the exception occurs.

[fiery tiger]

Thank you... so much. I learned a handful of goodies just googling how to do some of the things you suggested and I've got it working thanks to you! ❤️

[trim matrix]

if i wanted to say load a save game 1 time per event call, would it be a good idea to just load it in the actor that requires it?

i have a manager actor that will be writing into the save game once in a while

i'm not necessarily a fan of storing the save game object within a game instance, as it's not like the "main" save file and will only need to be used within a few levels. I have a few different game mode classes and adding the save game variable to each one of those just so it would work in the appropriate levels seems like a bad design choice.

i won't accept responses in the likes of "go c++", as i'd like to keep the project bp only (no world subsystems 🥲 )

[frosty heron]

The key word is "a few level". When you travel between level, your bp instance will be destroyed (unless it's stored in persistence object).

Game instance is your only option for a bp only project

Pretty sure world subsystem is per world but I never use it. Anyway any kind of subsystem is also cpp only.

@trim matrix

I mean you can always save and load before opening new level if that's what u want

[trim matrix]

.

during the game a few actors might want to access the current state of the game save

[frosty heron]

The only entities I differentiate is the settings, achievements and gameplay. Doing the gameplay in segments is a lot of headache, a good alt f4 will break the game

[trim matrix]

that would need to be a really precisely timed alt+f4

[twilit jacinth]

My ESC button does not trigger when I pause game. It looks like it is because of UI , but I dont even set Input Mode to UI only. Can anyone help ? Input Action has eneabled option triggering Inpaused state and UI is Focusable.

[random pulsar]

hi guys i want to make the wolf stop when it hits the player but it doesn't stop with the node stop immediately

[tidal marlin]

Where is your movement node

[random pulsar]

i realized i dont even need flip flop😞

[tidal marlin]

Stop movement immediately work with navmesh. And your movement is direct and you move on tick.

That means that you movement work, becouse you triggering add movement input every time. And stop movement not help to stop it.

[random pulsar]

so i can make the wolf with the ai rabbit logic but reverse it to run to player ,stop immediately and play animation,reduce the health and when player runs from wolf activate the movement of wolf and run towards player?

[frosty heron]

U stop it but you tell it to move again on the next tick? Have you actually change the bool value? The one that drives the a.i every tick.

By the way the whole setup feel like band aids. I would suggest using behaviour tree to control your a.i

[random pulsar]

Yeah there were also other persons who suggester behaviour tree,i will look for it,thanks

[gentle urchin]

Ugh, i should do that too instead of some bp brain tick

I've managed to avoid it for like 6 years now 😂

[frosty heron]

Behaviour tree?

[gentle urchin]

Yee

[frosty heron]

You used state trees I suppose? Not quiet sure what that is. I never actually work with A.I from scratch

[obtuse mulch]

how will this work if the value is 100++ ?

out range B will be always 100?

[frosty heron]

It will just be clamped

So if your value is over 100 you will get 100 as the return value

[modern radish]

a bit of a conundrum, perhaps someone has some good suggestion.. I'd like to "lock" the mouse to the middle of the screen until my PlayAllowed boolean is true.. this doesn't work, as the Exec gets stuck in the while loop.. how could I achieve this?

[frosty heron]

U don't get infinite loop error?

@modern radish

Loops are designed to be run in a single frame. If you don't have guarantee to get out from the loop in the same frame then you are not using the right approach.

Personally I don't have a single while loop in any game that I ever made. Don't see much use case

[gentle urchin]

No i rollee my own thing

[modern radish]

Yes yes this is totally busted, infinite recursion lol

You don't use loops for something like that.

Wrong tool for the job

[trim matrix]

but like this:

How would I accomplish it?

[frosty heron]

If you need to check every frame, do it on ticks

If it's a periodic check you can use timer

[modern radish]

Ah good idea

[frosty heron]

I would say do it on ticks, if you need to check mouse movement or if you are setting mouse position

it only doesn't appear there if "Private" is checked, but I don't want to private it

[frosty heron]

Well that's what private is all about

Is there protected?

[trim matrix]

but why would it even appear in the first place if "Instance Editable" is off

[trim matrix]

where can i find that?

[frosty heron]

If it's not there where you find private then it's probably not there

[trim matrix]

here are all the flags it shows me on that var

[frosty heron]

There are 3 types a variable or function can be that I know off

Public, private or protected

[trim matrix]

i think that only is the case for functions

not for vars

[frosty heron]

Deffinitly for variables too

[trim matrix]

at least not for that one

[frosty heron]

But prob protected is only in cpp

Since u need to declare friend class

[trim matrix]

https://tenor.com/view/ron-swanson-throw-computer-useless-mad-gif-9550833

[frosty heron]

Protected is like hidden but can still be accessible by other class if declared as friend

[trim matrix]

i get it, but i can't make my var protected tho

for whatever reason

[gentle urchin]

Bp

[frosty heron]

Ye not a bp thing

Just live with it I guess

Or step up the game

[gentle urchin]

Works for functions tho

All 3

[trim matrix]

im gonna just private it and make a const function to still access the var i guess

[frosty heron]

You will just be grabbing copies

And not be able to edit it

[trim matrix]

copies?

wdym

[frosty heron]

You can't change variable value in const function? I think

That's what const imply iirc

[trim matrix]

that's not a const func

i just wanted to show how the var gets assigned

[frosty heron]

I'm lost

[trim matrix]

me too

[trim matrix]

i don't want the vars to show up like this, so i need to private them

[frosty heron]

U said you want to make a const function for a getter to your variable. I'm just saying then if I'm not mistaken. That will be read only

[trim matrix]

yeah

i want to be able to access the component

to potentially modify its properties and stuff

[fiery swallow]

make it 7

[frosty heron]

Returning a reference should be fine but if you need to change a primitive data type, say a float or bool in a const function. I don't think you can do that

[trim matrix]

How do you make a random delay that can be instantly stopped and restarted at any point? SetTimerByEvent with random time, triggering itself?

[frosty heron]

Create a timer that call it self again upon finished. The timer shouldn't be set to loop for obvious reason

The set time can be random time

[pulsar pulsar]

So I have a hierarchy of MainParent (C++ class) > ItemBase (C++ Class) > BP_ItemBase > BP_EdibleBase > BP_TestItem. However TestItem doesn't inherit any of the functionalities that BP_ItemBase has, if I use TestItem to inherit directly from BP_ItemBase instead of EdibleBase it works as expected. Mostly the interfaces don't seem to work without the direct inheritance to BP_ItemBase. Is there some form of limit to parenting classes?

[frosty heron]

It should inherit 🤔

[pulsar pulsar]

Because what I do is a trace from the player to check if the actor i'm loking at is inherited from MainParent if it is then we go ahead and proceed but this goes false when it comes to TestItem being inherited from EdibleBase but true if inherited from BP_ItemBase

[frosty heron]

I don't think it's inheritance problem, could be something about the code.

If you get variable in your bp test item, can you see the variables or function from bp item base?

[pulsar pulsar]

oufff, negative. I just checked if i could get anything from BP_ItemBase but nope

[frosty heron]

Look at top right and see the class it's derived from

[trim matrix]

why can't i bind it to the function?

[frosty heron]

Make sure the chains of inheritance is correct

[pulsar pulsar]

Its EdibleBase

[frosty heron]

You can? It even have some compatible function listed below

[trim matrix]

no those are events (well the second one is)

[pulsar pulsar]

Yea it's correct, my confusion is high rn lmao

[frosty heron]

Have you got any function in that bp?

[trim matrix]

they are shown in the 2nd attachment

[frosty heron]

Did you have any input in the function?

[trim matrix]

yuppp... that's why i cant do it

🙃

[frosty heron]

Yup, need to provide compatible function or event

Same params, which is nothing with the case of timer

[trim matrix]

smh i even know how to do such a thing in cpp (bind a func with params)

[pulsar pulsar]

no wait iam able to call variables and functions, idk what i was doing when checking before lol

[frosty heron]

All is well then?

[trim matrix]

@frosty heron so the BP approach is to make as many duplicate parameter-less functions as i can have "states" for that function?

[frosty heron]

Should inherit the interface too

[pulsar pulsar]

Nope, Interfaces still don't seem to inherit and it's just sort of null when I do the trace check

This is the EdibleBase

This is TestItem inherited from EdibleBase

[frosty heron]

Go to your class setting and check the inherited interface

[frosty heron]

It's there right?

[pulsar pulsar]

yesss

[frosty heron]

I think your problem is right now, you are hitting the table

What do you actually print?

[pulsar pulsar]

The ItemClass

[frosty heron]

Show code

[pulsar pulsar]

of it's null it just say StaticMeshActor

[frosty heron]

Staticmeshactor is something

Show the print code

[frosty heron]

K I'm more convinced that you hit the table, check if the collision for your undetectable bp is set properly

For now you can print the actor instead the class

See what it give you

[pulsar pulsar]

BP_ItemBase, EdibleBase and TestItem have the same type of collision. It doesn't print the actor either, just hits the table

[edgy ingot]

Well the line trace it self doesnt care about your inheritance. It just prints the actor it hit. So imo this is deffinitly collision problem

[pulsar pulsar]

wait there's 2 of you 😂

[edgy ingot]

You can print overlapped component and the hit actor. See what that gives you

Yea my other phone is dying

[pulsar pulsar]

ahh

[pulsar pulsar]

rip

will check that rq

[pulsar pulsar]

wait, overlapped component? like the staticmesh?

[edgy ingot]

I mean hit component*

Just below the hit actor

Print them both

[pulsar pulsar]

hits the table

[edgy ingot]

So either the table is somehow blocking your item. Or your item dont have proper collision settings or collision body

Place the problematic one on the floor and see if u can trace it

If not, then i suggest to look at the collisoon setting and if the static mesh have collision

[pulsar pulsar]

The meshes have collision as they work if the class inherits from BP_ItemBase. This happens with any class thats 2nd down from BP_ItemBase for some reason

[pulsar pulsar]

It just hits the floor mesh etc

[edgy ingot]

Yup sounds like collision issue

[trim matrix]

what is the name of the dispatcher in a media player that triggers upon the media starts playing? (when opening the media and then doing play on it). I can see on playback resumed but idk if it gets triggered when the media wasn't paused previously

[edgy ingot]

Make sure ur collisoon setting is indenticsl to the working one

Nothing else to add at this point imo

[pulsar pulsar]

All look like this 🤔

[edgy ingot]

Thats for the mesh component? Or a shape comp?

[pulsar pulsar]

the mesh

[edgy ingot]

Make sure the mesh have collision

Show print screen of the mesh collisoon

[pulsar pulsar]

The food stuff is from the same asset pack. All the meshes work fine if inherited from itembase but not you know, EdibleBase

[edgy ingot]

That looks like complex collision

[pulsar pulsar]

yea but still. If I use this mesh and inherit from BP_ItemBase directly, it works

[edgy ingot]

I see

Whats below item base?

[pulsar pulsar]

currently it's ItemBase > BP_ItemBase > BP_EdibleBase but works if the bp class inherits from BP_ItemBase directly instead of BP_EdibleBase. I mean it's not a major issue but it would make things so much easier and better looking

[vestal jolt]

Can I create an input pin for a function that accepts a delegate?
https://i.imgur.com/CDbrCI3.png

[edgy ingot]

Bp ediblebase inherit from bp item base, so thst one work?

[vestal jolt]

I want to be able to connect this argument to the "Bind Event" Event pin
https://i.imgur.com/QzI8srL.png

[pulsar pulsar]

yup, if i set a static mesh inside EdibleBase and test on that it works fine

[edgy ingot]

Create a new child bp of ediblebase

Dont touch anything and just change the static mesh

See if it detects

[pulsar pulsar]

tf

it worked, i didn't touch anything. I just created a child class and popped it in the scene

[edgy ingot]

Deffinitly some collisoon setting is changed, accidentally or not

[pulsar pulsar]

hmm

ah ok so

[edgy ingot]

If not in the static mesh

Could be the parent

Of the comp

[pulsar pulsar]

If I create a new Blueprint Class and manually choose the parent, it doesnt' work

but if i create child class from EdibleBase, it works

idk why that should even matter but oh well 😅

[edgy ingot]

Afaik thats the same thing

But oh well

[pulsar pulsar]

it works now so haha, cheers for the help

[edgy ingot]

Pretty sure u can. Drag the red pin to the function

[trim matrix]

So do I enable the bool or not...?

[gentle urchin]

Just search by conext for "bind"

[trim matrix]

i did

and nothing

it only shows playback resumed

but i'm unsure if it triggers when the media wasn't paused

[vestal jolt]

it worked. But why does not it show a delegate option when you expand the type selection?
https://i.imgur.com/tBDRDGW.pngv

https://i.imgur.com/IO5u1aG.png

[edgy ingot]

🪄 but yea, you cant declare that as variable thru bp.

In cpp we do have to declare the delegate

I guess hooking into the function in bp does the work under the hood

[modern radish]

is this really necessary to be on Tick? I tried putting it on my EventBegin event, and it doesn't persist 😞

[trim matrix]

enabling and disabling it does nothing 🙃

[gentle urchin]

Try on the sound asset itself i guess

[trim matrix]

f that, i'll use both on media opened and playback resumed

[vestal jolt]

Can I declare a function parameter as optional (the delegate)?

[acoustic sleet]

Has any one come across such issue?
Why do the controls spazz out?
Its from the template too.

[trim matrix]

this keeps returning the default attenuation no matter if i override it or not

i have a deadline for the project and i can't figure this out 🪦

[edgy ingot]

Dont think so. I dont have editor on me but you can try

Normally ot scream at us when you dont even bind the assign delegate

[vestal jolt]

yeah it does right now...

[vestal jolt]

Ok. I tried to create a macro instead of a function. But when I''m trying to copy paste the Bind Event node engine says it can't do that for some reason
https://i.imgur.com/r5Dj4jI.png

https://i.imgur.com/jBBA034.png

[gentle urchin]

How would it know the underlying signature

Wouød you have a list of all possible delegates and signatures?

Gyess it could have a wildcard signature

[stark patio]

Does anyone know how i could go about making it so that my players camera smoothly leans when the player moves to the sides (it leans to the left if you move left and right if you move right). Currently i have tried making it with a timeline and that works but when the player swaps direction it snaps to the other side, i understand why this is in my code but not how to fix it, I have also made it using a lerp and the delta time which works but i dont really have any control over the curve. (I also tried a combined aproach but it had the same snapping problem as the first one)

(here is an image of the combo aproach)

[edgy ingot]

Set the beginning and end value (a and b for the lerp) before the timeline then use that for the lerp

Your point A and B shouldnt be changing accross the timeline. Right now you are using get control rotation and setting it. So every frame you incremenet the A input

[thorn tapir]

anyone know why this event doesn't fire?

the cast is valid and interface is implemented

[proven garnet]

Hey people! I'm trying to make a simple pickup BP parent which I can then change to whatever I want in the children. Logic is when the character overlaps the BP I'll just print hello to see if it works. later I'll destroy it. But when I overlap the BP with the character (blue cube) it just doesn't work. Can anyone see what I'm missing here?

Okay weirdly enough when I just change the mesh to the default cylinder it works. Anyone knows why?

[stark patio]

ah i see, i fixed that now. But the problem of it snapping to the other direction is still there

[thorn tapir]

ok I see now, it's because the interface is inherited from the parent while the parent doesn't explicitly implement it

how do I call the inherited interface event on a child?

[gentle urchin]

Wrong event ? You want message i believe

[thorn tapir]

still doesn't work

[proud wasp]

why does this happen every time i launch the editor?

[gentle urchin]

Is the message event triggered?

[edgy ingot]

Show your latest bp

[edgy ingot]

Those bps didnt compile because u broke something

[proud wasp]

i didnt

i have to refresh them

and they work

but why do i have to do it?

every time

[edgy ingot]

Check the error

[stark patio]

and this is dragged in to when the input action move

[proud wasp]

@edgy ingot

[thorn tapir]

yes

[edgy ingot]

Well there you go. You did break something

[proud wasp]

no i didnt

[edgy ingot]

Look at your 2nd pic

[proud wasp]

i told you

[edgy ingot]

K if u say so

[proud wasp]

if i just refresh

it works

how do i fix that?

[edgy ingot]

You go to the node you break

Refresh or delete it

[thorn tapir]

the hierarchy goes like this:
TestVehicle : UnitBase
UnitBase : IUnit
when I call MoveTo on IUnit the event runs on UnitBase but not on TestVehicle

[proud wasp]

i cant do this every time tho

[edgy ingot]

U shouldnt need to do it every time

[proud wasp]

it also unsets everything on the blueprint fields

yeah why does it happen tho?

[edgy ingot]

It pops up because u didnt fix the broken node

U break something

Some ref that you used to have on some node, no longer exist

[proud wasp]

i have to live compile

and then everything works

[edgy ingot]

Or you can fix the broken node 🤷‍♂️

[proud wasp]

how?

[edgy ingot]

Compile and save

By going to the problematic node. Refresh or recreate it

Read the error msg

[proud wasp]

thats the error message

[edgy ingot]

Yup

I cant say anymore than what i already said

Fix your node

[proud wasp]

why do i have to do it every time tho?

[edgy ingot]

U dont

U never fixed it

Thats why it scream again when u open later

U just click compile, thats not a fix

[proud wasp]

i did everything

compile

refresh

[edgy ingot]

Did u do what i suggest,m

Which node did u refresh?

[proud wasp]

compile the blueprint

the ones with errors

[edgy ingot]

Then u dont have to do it again

Fix, compile, save

Seems like u took away something that is used in many places

[proud wasp]

no

i didnt

[edgy ingot]

Ur latest pic not even the same one as the previous one

[proud wasp]

it worked last time

ok now i did what you said

time to restart the editor

it happened again @edgy ingot

[gentle urchin]

You can always wrap it in a new custom event which you override in the child i guess

[edgy ingot]

Check the error again

[proud wasp]

its the same error

[edgy ingot]

I dont know if you actuallt refresh the node with red marks because u break something

And u have a lot of broken bps

[proud wasp]

yes i fixed them

[edgy ingot]

And claimed to fix them all in short notice

[proud wasp]

the game run

[edgy ingot]

So im not convienced

But yea i have no idea other than that

[proud wasp]

why arent you convinced?

do you want me to stream it to you?

[edgy ingot]

No

Ive stated why

[proud wasp]

why

[edgy ingot]

Not here to argue anyway

[proud wasp]

ok then how do i fix this?

[edgy ingot]

Just telling u what i think is wrong

[proud wasp]

its not that

everything works

[edgy ingot]

If u say so

[proud wasp]

i click this

then go

refresh nodes

and compiled

same with the rest

[edgy ingot]

Cpp project?

[proud wasp]

yes

[edgy ingot]

K u didnt build from there

Prob u pull someone commit

But didnt build in ide

[proud wasp]

?

[edgy ingot]

Go to your cpp and build from there

[proud wasp]

ok

[edgy ingot]

Close editor first

Close editor, build, run the game. Profit

Its the only time i encountered such error

My brother pulled my commit but didnt build from ide

The fix was to just build from ide

[proud wasp]

ok that worked

[edgy ingot]

Its weird if it happend when working on solo project. My assumption is u work with someone that does the cpp stuff.

When you get the work, u only get the cpp and header file. It is not yet compiled, hence you need to always compile when when you pull from git repo

[proud wasp]

no i do everything

(suffering)

[edgy ingot]

K then i have no idea cuz for the cpp stuff to come out, dont u need to build the project

[balmy carbon]

Hey! I made a MasterButton for my blueprints and exposed the variables for text style/button style etc. Is there a way to change the title from "Default" (on other blueprints) to anything else? Or maybe some subcategories for each (text style, button style etc)?
Just for more organization 😄

[edgy ingot]

So you want each instance to have custom text?

[trim matrix]

is there a built-in node for finding elements that exist in both arrays?

[edgy ingot]

Can always make one in your own blueprint function library

Takes a min

Get array a, get array b. If found and found, return true

[balmy carbon]

I think!? for example in the picutre the title is Default (there are only the Text Style variables) so the title should be "Text Style" or something similar.

[edgy ingot]

Hmm im kinda lost, not sure what you mean sorry

[edgy ingot]

You cant change the category name, dynamically if thats what u r asking

[balmy carbon]

That was what I wanted to explain now, haha. It's ok, thanks. Just wanted to be more organized cause I'll have more variables. Thank you

[edgy ingot]

Typically u dont need to see a page of variables

If you have a lot of variables for specific stuff. You can always use structs

[trim matrix]

the problem is that i can't use wildcards in a func library. And a macro library is class exclusive

[edgy ingot]

Eg, inventory data should be stored as a struct. You will end up with one line instead of a page of variable

[edgy ingot]

Rip. I dont know if theres inbuilt function for that, but maybe someone knows

[balmy carbon]

Thank you, will try

[sweet silo]

hi there how would you a create a "tearing down posters" system ?

like this but you would see the poster being taken down

i know how to swap mesh but you woudln't see it being taken down in real time kindof

[trim matrix]

there isn't a built-in sort array either?

[edgy ingot]

Nope, but there is free plugin for it. I think

[trim matrix]

<guy throwing pc into trash gif>

[edgy ingot]

Its probably int exclusive sort?

[remote meteor]

https://tenor.com/view/i-hate-my-computer-gif-18858423

[edgy ingot]

I helped someone did bubble sort once

Never find a use case for my self ( yet )

Theres deff some plugin to sort array i just never bother downloading one

[remote meteor]

Epic should have just expose the cpp ones 🤷‍♂️

[trim matrix]

nah i can do the sort but

[trim matrix]

.

[remote meteor]

Low Entry Extended Plugin does it

[edgy ingot]

Ye not sure how wild stuff even work in bp setting. Afterall u have to define the rule for the sort?

Like sort array of actors but based on what?

In cpp you can overload

[remote meteor]

Do it exactly like the plugin does

Wildcard stuff can work on bp through CustomThunk

[trim matrix]

f it, i'm doing a sort function myself for every possibly var type (that i'll need)

[remote meteor]

Well i will recommend the LE plugin

Its free and has bunch of useful stuff

Including all the sorts

is there a way to get a camera view to show as an texture instead of having to take screenshots of every item you have?

[pulsar pulsar]

ah, will have to look into it, cheers

[trim matrix]

Hey, so i'm using PaperZD to create a point and click where you would click a specific icon on screen to go to another location, all locations are going to be images, what would be the easiest way to change the onscreen location? would I just be able to create a UI blueprint with everything that would be onscreen and swap them out when the player changes location? and how would I add in a cutscene (for example the player starts on the main menu, clicks new game, fade to black, then it fades back in to a cutscene), how would that be possible?

[misty badger]

Is it good idea to store Data Assets in Game Instance as array?

[pulsar pulsar]

but would I need a RT for every item then instead?

[trim matrix]

you could how them be created once for every item in inv

there's a node Create Render Target

[pulsar pulsar]

is it possible to switch the render target into a texture2d once created?

it seems to be possible but it's Editor Only

[trim matrix]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Rendering/CreateRenderTarget2D/

it outputs a 2d rt texture

[pulsar pulsar]

No, It outputs a Texture Render Target 2D object 😅 I guess I could just switch the icon variable to the same though

[trim matrix]

you can get a texture out of it tho

(at least i can see the func for that in the cpp side of the docs)

if not, then you'd have to make multiple dynamic material instances 😉

[honest flame]

i have an interactable blueprint, this has a widget component which itself has a widget class, in the widget class, i have a binding that updates the name depending on the interactable blueprint name, how do i get the widget component from the widget class inside of this binding?

[pulsar pulsar]

Just what I was hoping for, but I can't seem to use it in blueprints though.

[thorn tapir]

turned out the blueprint was corrupted for some reason and didn't link to its parent correctly. I had to create a new one and it worked

[pulsar pulsar]

Searching through the discord, it seems ConstructTexture2D is not available in a packaged version of the game anyway 🤔

[gentle urchin]

Interesting. Reparenting didnt work either ?

[thorn tapir]

I think reparenting might have caused this but I'm not sure

[pulsar pulsar]

So then, its either mat instances or screenshots lol

basically the same tedious process

[trim matrix]

nah, u know what dynamic mat instances are?

[quick grove]

hi, I'm making a murder mistery game, where the murders have a red color name and only them can see other murder players with red name color, in multiplayer, event and replication how can I do that?

I created an enumerator with 2 different roles (normal and murder), and I even created an enum var inside the character

[pulsar pulsar]

Not really

I have zero experience with them

[trim matrix]

https://www.youtube.com/watch?v=IVKVXjaT6QM

[frosty heron]

#multiplayer but sounds like all you need is just information if the player you control is innocent or murderer.

If murderer then set texts of other murderer to be red

You can just assign the murderer and innocent on server side and then rpc to client before drawing the texts

[quick grove]

I want to try make this that if a player joins it updates

[frosty heron]

You need to set the replicated variable on server side. Replication only happend one way. From server to client

Not client to client

[obsidian arch]

hey all is there a way to differentiate between a right and left click with this node?

[frosty heron]

Take it to #multiplayer channel where the experts are

[frosty heron]

Not with that node no

[quick grove]

ok, thanks

do I need to delete the messages here to write in the multiplayer channel?

[obsidian arch]

ah unfortunate, I want to have different things happen when you right or left click a button but Im not sure how to differentiate between the two

[frosty heron]

Cross posting isn't allowed but I am not the police

[frosty heron]

There are ways to detect key inputs in the widget

Using the on key pressed event

But it's a bit painful to detect right click for buttons

[obsidian arch]

yeah

[frosty heron]

If I have to do it, I will make a custom button widget.

Inside it will detect right click pressed. I will then check if when right click is pressed, check if the button is currently hovered or not. If it is then run a custom event or function, if false do nothing

so your saying the continue game button isn't working ?

what is that code look like ?

you probably don't want to keep creating in the pause game event

Hi guys, can you please help me with this BP? I do have this static mesh with a box that ends the game and another one (in the floor) which is a trigger. Then on begin overlapping it rotates the tree and falls to the ground and then I am trying to roll it with an actor movement of local rotation. The problem I am facing it is that the trunk is rotating like a clock and moving rather than just rotating and rolling. Is it possible to find a way where it is rotating by itself (so I can make it look like is rolling ) please?

[torpid yacht]

When i bind an event on an actor's begin play, do i also have to unbind on that actor's destroy to prevent memory leak or does it automatically take care of it when the actor is destroyed?

[tiny monolith]

How do I turn my gun in the direction I fired the bullet?
Let’s have a gun and let my character turn in that direction in the direction I shoot the bullet. I can shoot bullets, but how do I rotate the gun and the character in that direction and at that angle? I found the angle, I printed it and checked it, I created a flipbook according to this angle, I have a character with a gun in his hand, but it doesn’t work when I create it. Help me (2d game)

[barren dove]

I haven't done any flipbook stuff, but in 3d I would rotate actor
in this case I imagine you need to take the rotation and then translate it to the correct flipbook frame for that angle

[trim matrix]

It should take care of that for you

[tiny monolith]

I have already taken the angle and when I get to that angle I print "hello" and it works but the animation does not play.

[cursive ermine]

Hey everyone!
I have a quick question. Does anyone have an idea how I could compare two vectors if they are the same (but with some tollerance).
I am trying to compare the actual Location of an TargetActor with a possible SplinePoint Location.

Bute everytime The Result ist False. eventhough the Actor is at the exact position as the SplinePoint

[solid sonnet]

Can somebody help me? My trigger box is triggering even though im not in it. (if i get remotely close to it) It might have to do with the fact that it is parented to AI but im not sure

[cursive ermine]

I even tried it with a Tolerance, but to be honest I couldnt find eny information about the scale if the tolerance so I just tried random values between 0 and 100.. But nothing changed

[cursive ermine]

You should add an quick Check about the Class of the overlapped Actor. If you leave it like this every Actor on your Map triggers this event. But with such a Check this can be prevented

[barren dove]

Not complicated, but I feel there's probably a BP that does it easier
I would take the player location, break out the vector add and subtract your tolerance value from each XYZ , and then compare the xyz to the broken out vector of the other half

Probably make a function out of it

[cursive ermine]

Like this for example

[solid sonnet]

Ok, thank you so much!

[cursive ermine]

oh.. right I could try that. Thank you!

[dawn gazelle]

That's a fairly tight tolerance - it is based on Unreal Units like you would see when modifying the location of something. What you have there is what you would be doing to test it. Perhaps print out the two values so you can compare yourself to see?

[barren dove]

hey, question

I have an actor with multiple collision shapes, the idea here is when an item enters a radius, it moves to the character, then when enters the inner one, we collect the item

my trouble here is that overlap is based on the entire actor, I could create an actor for just the collection radius and attach it to the actor, it seems sloppy, is there a way of breaking out which collision in an actor is generating the overlap event or should I do it the sloppy way?

[cursive ermine]

With some testing with values I crafted (like GodForge suggested) an own Function with Tolerance that checks if they are the same. This worked for me 🙂

[barren dove]

oo nearly equal, I discovered a new thingy today XD

[lunar sleet]

use component overlaps

[barren dove]

so on tick run component overlap actors?

[lunar sleet]

not unless you're spawning things directly overlapping

onComponentBeginOverlap is what I meant

[cursive ermine]

You could try Component Overlap. That worked for me. Just checking everytime something overlaps the entire Actor what excatly it overlaps (what component of your Actor) and excute depending on that this or else code

[barren dove]

ah okay, so I'd drop this in begin play to create the event then feed off of that

[lunar sleet]

you don't need to bind

either right click it and add event or select it and scroll all the way down in the details panel

they give you the bind just in case you want to use it that way, but the event itself will fire when overlap begins, just like the actor one

[barren dove]

doesn't seem to exist by default

[lunar sleet]

no no

right click the component

in the Components tab

[barren dove]

ah ha, thats what you didn't mention, i got it now

[lunar sleet]

I thought I was specific enough with that "it", mb

[lethal night]

Has anyone got any clue why this Behaviour Tree task is never finish executing

It gets stuck here

[lunar sleet]

#gameplay-ai is a better channel for this

[lethal night]

ah mb

[barren dove]

if the cast fails your AI will never advance and will stick there forever

[lethal night]

Ah

right

I realised what i did wrong lmao

Im casting to the wrong thing LMAO

[barren dove]

you need to make a little loopy guy that finishes that node for all conditions, if it doesn't complete you're boned 🙂

[lunar sleet]

a little loopy guy eh? I like it

[dawn gazelle]

I think the difference is that the standard method is checking if the target locations is within the tolerance, where with what you're doing you're individually checking the positions of each are less than the tolerance.
eg.
If I have a vector that is 0, 0, 0 and my actor is at 3, 3, 3 and I'm checking the distance between them with an error tolerance of 5, the default way would return false as the distance is actually something like 5.19.
In your case, you're checking individually if they are within 5 units each, so since all values are <5, your function will return true.

[sick sky]

how does the LSV works ?
does it triggers on begin/end overlap ?

for example,
if my player is in a LSV (the linked level is shown), from BP i manually unload & hide it, if i move, will the level be back loaded & shown ? or do i have to get out and back in to trigger again

[cursive ermine]

ohh... makes sense

[keen widget]

Trying to do loop for every items and get different variables in them to set them to different structures
but for some reason every structure get set to the same last item varible.. why ?
what im doing wrong?
My logic was this:

1. look inside first item take its name Alex and then set it to ST_AttackMacro1 name var
2. look inside second item take its name Nicolas and then set it to ST_AttackMacro2 name var
   ...
3. look inside second item take its name Tisha and then set it to ST_AttackMacro2 name var
   but right now they ALL get set to the last name Tisha from last item

[lofty rapids]

so whats in the collapsed graph ?

[tiny monolith]

I want my gun to angle and my character to turn to the direction I'm shooting.I found the angles and I can interact.How will the gun I will use rotate at the angle at which it is fired? and My character also needs to turn in the direction that is fired.(my game is 2d)

[lofty rapids]

if you reorder the make array, is it using the last one ?

[keen widget]

yes all varibles get set to the same item for some reason

[keen widget]

but this simple test works for some reason

[keen widget]

oh, sorry, i was dumb, i was looking in the wrong debug info, its working..

[lofty rapids]

i was looking at it confused af

[keen widget]

ty, blueprint debugger pluggin saved me

[keen widget]

for SOME reason unreal5 default debbuger showing wierd stuff
like this:

why its showing me 1st item when im mouse over the 5th, that what was confusing me

[pastel garnet]

is there a away for the input to fire even when the game is paused?

[gentle urchin]

Its a setting

For that input

In the input action

Hi, I'm having an issue where I'm trying to bind on audio finished to another custom event. But it says accessed none every time I try during runtime. The random dialogues array is also instant editable but it's still broken. Any ideas?\

[trim matrix]

Hi all I have a level which is obvs unloaded and loaded back in depending on if player is on or on a neibouring tile. This has cause an issue where an actor that is always loaded is loosing hard references to an actor in the level but only when the level is loaded back in.

[pastel garnet]

Thanks i didnt see it earlier

[trim matrix]

Should I be using soft references for stuff that need to be references when the level loads back is or am I missing something

please note I'm on the TSW editor so limited to what I can implement

[tall veldt]

Hi everyone, new here! I've got a question:
So I want to build something similar to RCT. The terrain is flat, but is a single plane filled with grass-textures (e.g. 64x64 so 4096 tiles big). I want to give that a material where i can change e.g. tile x:12, y:15 with sand, so the material updates itself and switches out that specific tile.

Is this possible? Or should I render a smaller plane of 1x1 per grid tile?
If the single plane is the way to go, how do i go about it handling getting the data into the material?

[sick sky]

Hi
In a parent BP, i would like to call a event dispatcher when a interface event is called, the issue is that because in each child the interface event is used in the graph, its overiding the parent one
is there a way to do both ?

[charred berry]

Trying to get buoyancy working on mesh, went by https://docs.unrealengine.com/5.3/en-US/water-buoyancy-component-in-unreal-engine/ , but nothing is working. ]

[dawn gazelle]

You can right click on the event node and add a call to the parent event.

[charred berry]

last attempt I added 'scene' components as buoyancy objectgs, though Im not even sure what that means, so I used spheres ?? and placed them inside mesh

pasting location to buoyancy location

[sick sky]

ty, but isnt there a more automatique way ?
its annoying to add an extra node to each child

[dawn gazelle]

Any time you override a parent function, you're saying "Do this instead". To ensure that the parent is called, you have to declare that you want the parent called and you can even decide when the parent is called.

[sick sky]

okay ty for the extra info

[dawn gazelle]

Even in C++ land you have to call the Super() of the function to get the parent class' execution to go through.

[sick sky]

its just annoying the first time because i have to get to all already created child xD

[stone dirge]

In my fps game i have linetrace shooting but for some reason when i walk backwards the shots go to the side randomly and I dont know why. The code is really basic here it is:

[opal kraken]

Guys in my project i introduced those kind of obstacles, but the collision with my character does not work properly, but with a sphere you can see that works perfectly, any clue or suggestion to solve it?

[carmine palm]

For enhanced input action I'm calling the IA Event. How do you check if the event was left mouse on right mouse button?

All I see is this currently

or do I have to add an IA Event for singular actions

[grave halo]

You should have two different input actions and then merge them on a inputMapping called IM_Combat to have it more tidy and you can add more combat inputs if you need it in the future

Then call EnhancedInputAction IA_LMouse and then the RMouse or whatever name you prefer

[carmine palm]

awesome ty

Didnt know if I could have IA->getControlBinding

lol

[trim matrix]

guys i'm having a problem with my game, where can i ask for help?

if i want to filter out all the components without a tag from a Component Begin Overlap and End Overlap how can i do it?

[grave halo]

In the other actor node you cant get the array GetAllActors??

[trim matrix]

ok, now how can i use the array to filter all out (i started like 4 days ago, i dont know much)

[grave halo]

do a foreach and use a branch to know if has the tag or no

with the node get tag name

[trim matrix]

thanks ill try

[plush hornet]

Hey all i hope your well. I put a post process volume in my level and tried to adjust the focal distance and depth of blur because i want to adda depth of field effect, but it doesnt work no matter what i try to change. any helps appreciated. Thanks

[versed sun]

did you set the Post Process to unbound ?

OR make it big and get inside it ?

[plush hornet]

Your a star🤗

[trim matrix]

unfortunately i cant get it to work with that method but i found this category in my collision box, maybe i can set it to only blueprints or something?

[pulsar vigil]

Hey, i can’t wrap my head around getting the input action pressed making a ui widget to react to it,

I did make work another widget react to an input action but it was only about toggling a boolean and message the value in an event dispatcher

Here i want it to work this way : the moment i press the input, the horizontal box that contain element i want to rescale, rescale at the same time for the same duration.

[dawn gazelle]

Input actions are just events.
You use that event to drive logic.
If you want something to do something based on that event being triggered, you either have to tell that thing that the event is happening, or have that thing listen for that event.
If you want something to do that something based on certain criteria, then you have to have some means of differentiating when it can or cannot do the something.

[pulsar vigil]

ok i see thx

[thin panther]

try this instead, the above solution is flawed and will not work.
drag out from other actor and the "Actor has Tag" node

plug that into a branch and bob's your uncle

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Utilities/ActorHasTag/

[trim matrix]

i need that the collision box detects only the things that i say, i'm trying to get a specific mesh to get detected and deleted

[thin panther]

then, hold a reference to that mesh elsewhere, and check if that refernce is equal to your overlapped one

[dawn gazelle]

You kind of only have two options...
First is if you're able to get the "Other Comp" which should return the component that is triggering the overlap, in which case you can check if that component has a tag.
Second is using appropriate collision settings which is what you were looking at a little earlier, but these need to be set up on both the thing detecting the collision and the thing causing the collision, in which case it would trigger the collision event only when you want it to happen.

Hey all, I'm trying to control a parameter (Hight_Mask_Bias) in a material (m_SimpleVolumetricCloud_Inst) from within a blueprint seen in image two. How can I go about doing this?

[stark patio]

I have tried for 4 h to make my first person players camera lean towards the sides when the player moves to the sides (or diagonally etc) and i have not gotten it to work. at best it leans smoothly to one side but then snaps to the other. Id like to make it using a timeline so that i have more controll over the curve. Seeing as all of my attempts have failed i obviously need a new aproach, does anyone know how i could do this?

[shell flower]

So, how would one go about making a Persona 1-esque (I have no idea what it's actually called, but first-person grid-based, if that makes sense?) movement system? I have been trying for days and just can't figure it out...

[radiant cape]

i need to loop through only the first 10 values in an array, would you just increment a number each loop and break when the threshold is met?
seems messy but that might be life

[frosty heron]

Just do a for loop

Breaking is fine too if you are not guaranteed ti have 10 values in the array

[radiant cape]

oh oh and just use the get array node niice ty haha

[frosty heron]

Incrementing number is not messy, that's what loop does under the hood

[small wedge]

how can I get this in blueprints? I'm trying to control parameters from my metasounds, and it looks like I need to use this, but I can't figure out where I can get this from.

I've already created an "Add Audio Component" to my Event BeginPlay, and the sound is playing on begin play.

[elder lodge]

Are there standard nodes for handling yaw and pitch correctly after applying roll? Or do I have to do some trig with the mouse input? Is doing it in the character class best practice?

[lunar sleet]

#audio is your best bet

[small wedge]

even if I'm asking about the blueprint side of things?

[lunar sleet]

Yeah, those nodes are specific to audio. That’s why we have specialized channels

[small wedge]

alright will do

[waxen fog]

Has anyone created a good knock back in unreal before? I find launch character node to be kindof jank

[dawn gazelle]

This aparently isn't required anymore. You can set parameters directly on the component through nodes like "Set Float Parameter" or "Set Integer Parameter"

[carmine palm]

How can one get widget reference from BP?

er

from Hud reference

or component

my b

[mental trellis]

Start again. Where do you want it and what do you want?

[carmine palm]

I have a bar on my main hud

I want to access said bar

from another bp

playercontroller->gethud->whattodohere (obviously its in blueprint form)

[mental trellis]

Are you using a hud actor to manage your widgets?

Get hud will return the hud actor created from the hud class variable.

If you aren't using that, get hud is probably the wrong method.

When you create your hud bar. Save it as a variable. Make that var public. Get that var. Do that either in your player controller or in a hud actor bp that you set as the hud class.

[carmine palm]

oh okay

[carmine palm]

Any ideas?

[barren dove]

Any idea why a text widget would be displaying as semi transparent even though its pure white? (0,0,0,1) , no material

[dawn gazelle]

Do you have a second copy of your editor open?

[carmine palm]

No

[lunar sleet]

Only other thing I’ve seen cause that is the auto save bug

[dire frost]

That's weird cause the text is not transparent evident by the fact the partical effect is hidden behind the writing

Have the colour of the text be (255,255,255,1) instead

[frosty heron]

Ahh yeah it's not transparent

[barren dove]

its not white either

[carmine palm]

Auto save bug?

[lunar sleet]

Wrong widget or are you changing its settings dynamically?

[barren dove]

no and no

i changed it from red to white, red was also pale trashy transparent looking red

[lunar sleet]

Sometimes the auto save glitches, so it looks like it’s trying to save the map but it’s just trying to overwrite the auto save

[carmine palm]

Well that was me trying to save manually

[lunar sleet]

How much work will you actually lose if you force it to close?

[lunar sleet]

Try #umg then, they have more knowledge on this stuff

[carmine palm]

I closed it lol

And reopened it

[runic pagoda]

Just wanting to sanity check - is there maybe a more succinct way to get this result? Lyra inventory (I think anyway) seems to be tied to the 'controller', and I couldn't think of another way to get the controller without casting like I did

[keen widget]

Is there a way to create array made out of other arrays?
or something like that

[dawn gazelle]

Create a structure that can contain an array of your desired items, then you can create an array of that structure.

[fiery swallow]

I mean you can append arrays

as in, Add items from Array B to Array A

[keen widget]

can i add new items(arrays) in to structures in runtime?

[runic pagoda]

Is there a better method of doing this? I want to send the 'GameplayEvent' when the weapon ends a shoot-cycle (so the boolean changes from true to false).

[pale mica]

Why does 'Set play rate' not have a target? i need to connect the array elements to the target

[gentle urchin]

No

Well

You add another struct entry to your struct array

Which in this case would hold another array

[keen widget]

yes! that what i need 🙂

[gentle urchin]

So "yes"

[keen widget]

how?

[gentle urchin]

As Datura said, create a struvt that holds an array

[tiny monolith]

When my character turns in the direction of my mouse, when I want to walk, it walks backwards.
My mouse turns right when I'm on the right side, but when I try to walk it walks backwards.

this is the wolf logic and i want to make 2 more animals rabbit and wild boar how can i do this? do i need to make from scratch all of them?

[trim matrix]

Can you even do that with BTs?

[random pulsar]

?

[trim matrix]

like derrive them and stuff

[random pulsar]

i dont know man i just made the first behaviour tree watching a tutorial

[trim matrix]

#gameplay-ai should know this

[random pulsar]

oh,this is a separate channel)

thanks

[trim matrix]

but if you were able to run an another BT from within a BT

[trim matrix]

you could separate that part i guess?

and reuse it

[gentle urchin]

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Math/Transform/InverseTransformRotation/

[trim matrix]

from the docs it doesnt seem like it

[gentle urchin]

I think you can, im just not sure how

Swapping it at runtime?

Also more #gameplay-ai

[trim matrix]

i guess so, but swappng at runtime wouldn't allow u to do stuff in the same way i think

at that point it would be better to remake it into an entirely bp only controlled ai

[neon burrow]

For whatever reason my camera doesnt move when crouching ?

[trim matrix]

show crouching camera pos switching code

if u have something like that even 🙂

[neon burrow]

it worked before but now it doesn't

the collision capsule is moving correctly

but the camera is not affected

[trim matrix]

oh so u mean the camera doesnt lower?

[neon burrow]

yeah the capsule goes when i press C but the camera stays the same

[gentle urchin]

"The same way"?

Whats that way

[trim matrix]

I thought you meant it doesn't follow the player at all lol

[gentle urchin]

Only thing you might miss is proper transitional view , or subtree view

[neon burrow]

no, it just doesnt "follow" the crouch position

[trim matrix]

Show how the camera is attached

[trim matrix]

i think if you had it attached to the capsule it would lower

when it would shrink

[neon burrow]

tried doesn't it brakes the view

cameras stays in the same position

2 sec let me try something

[trim matrix]

do you have any anims?

Maybe the crouching anim doesn't play now

[neon burrow]

no anims

[trim matrix]

i got no idea how it could have been working

before

then

[neon burrow]

let me try to redo it or something ... ughh

love it when stuff doesn't work when it's meant to work

[trim matrix]

i wasn't refering to anything specific. for that bt, yeah you could separate it into 2 BTs and then switch on them

ur ✅

[frosty heron]

Why wouldn't it be?

Nothing in the code change the camera position

It only change the capsule half height and offset the mesh

[steady night]

Hey Guys how would i get "The Closes withing Range" of all actors from class ?

[frosty heron]

Closest from where?

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Utilities/FindNearestActor/

[ionic crescent]

dang i been doin a for each, checking distance, if distance is less than previous make that one the closest etc etc

didnt know about that node

[young meteor]

Same 😄

[ionic crescent]

i thought there would be so i searched "closest" in nodes but not nearest

[neon burrow]

then why did it work before?

i didn't change the code or anything

[frosty heron]

No idea with what you actually see from your end

[neon burrow]

if you also look at any tutorial there is no code for the camera

[frosty heron]

Sure thing because Ur camera doesn't change from the crouch or uncrouch function

[neon burrow]

it automatically goes down with the collision capsule

[frosty heron]

It could be placebo I don't know what you see

Actually wait I'm wrong

The camera do change because the camera is the child of the capsule

But it would be instant

[cinder thunder]

Question: is there a way I can launch an .exe with command line parameters from a blueprint during runtime (this won't be a packaged project)?

[neon burrow]

exactly and for me it doesnt do that

i can clearly see the capsule going half height

and camera stays exactly the same position it was before

the capsule is not affecting the position of the camera

and i have no idea why

[frosty heron]

I just did crouch a few days ago , iirc mine also stay but that was my intention

You can always lerp the camera if u want to change the position smoothly

[neon burrow]

yeah but the camera doesn't move, so first how would i make it collide with the collision capsule
so it moves it down

i know i could "tp it smoothly" to the location

but it should work without it

[frosty heron]

#blueprint message

Open console and type show collision. See if you actually crouching

[neon burrow]

i have it visible

not crouching vs crouching ( don't mid the model lmao )

it slows me down - it shows that it's crouching
but the CAMERA just doesn't move

When i jump and then crouch for like 1 sec i see some Camera glitch ( weird movement )

[versed sun]

Something like this

Put the file path to your .exe in B

you can also open folders (what I use it for)

[frosty heron]

That's scary lol. Imagine the game open some .exe file

[versed sun]

🙂

[frosty heron]

Could be key logger for all we know

[versed sun]

my thoughts exactly

[frosty heron]

There is one damn free steam game I download

Freaking mining on the background

[cinder thunder]

@versed sun yes. Are those built in nodes?

[frosty heron]

I was wondering why it's soo laggy

[steady night]

@frosty heron Oh dajum thers already a function for that thanks!

[versed sun]

Built in yes, but it might be a plugin you have to enable

[trim matrix]

bro... they can use c++ for unreal

[frosty heron]

You still have to specify the location tho. Closest from which point?

[trim matrix]

it's possible to add malware into the game itself

[steady night]

I could just get the actor location

Thats finebim just tryinh to find wich player is closest to x player

[versed sun]

if you cant find it , try this plugin

[trim matrix]

launch url isn't a part of that plugin i think

[steady night]

Altho i dont like the get all actors from class but i mean its not a tic function or anything but still

[frosty heron]

Tick is very useful

Some code only belong there

Many things run on ticks

Don't let youtuberd feed you false information because they didn't use tick correctly
