blueprint

[eternal flame]

I have tried MoveComponentToLocation but it does not work

Can you show this with timeline? On blueprints?

I am very new in ue5

[gentle urchin]

Timeline -> alpha -> Lerp transform

Start transform -> end transform

Add noise along the way

[eternal flame]

Physics not necessarily important first

[gentle urchin]

Separate curve for example

Id prob write a function for the noise but oh well

[eternal flame]

Okay I will try, some small example on blueprint would be very grateful for that

[zealous moth]

I would but my GPU is full atm

[eternal flame]

Thanks

[gentle urchin]

Did you forget implementing the EmtpyGPUCache ? 😄

[eternal flame]

Yes exactly, I can even create several curves for corresponding axis

I just want add more realism in scene

[zealous moth]

nah, I'm running A1111 and I got an XYZ plot going on; it's gonna be a while until I can do anything other than discord chat

[eternal flame]

Thanks anyway! I will learn about more complex usage of timelines

[west crescent]

Is there a way to create a struct from blueprint variables or a tool that can do that?
I would like to be able to select multiple BP variables and then create a struct that contains all of them

[gentle urchin]

A1111?

[zealous moth]

an AI gen

I need some backgrounds, so I am running several models in series until I can get what I want

fishing for seeds or good results 😉

I tried to get a bathroom once...

it didn't quite get it

[gentle urchin]

Lol

[lunar sleet]

Computing all those toilets is hard

[silent drift]

I mean... I guess the classic meme "Compete in the bathroom" and this would make sense. 😄

[hearty sand]

AI thinks privacy is useless and inefficient

[zealous moth]

here it got close to it

but i think it thinks toilets are people

you can see one coming out and the other washing hands

anyways, this sort of stuff

[lunar sleet]

No, that’s just the public bidet

[zealous moth]

hahahaha

[gentle urchin]

In many ways it is

[zealous moth]

behold

0 privacy AND challenging

[hearty sand]

the washroom of zuckerbergs dreams

[frosty berry]

nope

[lunar sleet]

Looks a lot less cartoonish and more Pixar

I do like the “head of the table” one

Looks like a bathroom+ conference room

[dire frost]

why is #blueprint full of drawings of bathroom stalls?

[frosty berry]

Is there a way to print out a message when a projectile hits end of life? No collision.

[dire frost]

on destroyed event

[gentle urchin]

We're infected by some OT fungus thats spreading...

I believe patient 0 was in ||cpp||

[dire frost]

OT? and a fungus infection makes me think of a the last of us type of situation not posting endless amount of bathrooms

[dire frost]

i'd expect this from a rust developer tbh

[modern radish]

I'm looking at a way to use some FishEye post processing effect, but I quickly realize my actions on screen which rely on hit results under cursor start to mismatch with this approach.. is there a way to have a similar hit query but taking that PP distortion into account?

[gentle urchin]

Off Topic

[dire frost]

oh i was thinking it was bathroom related lel

oh god i think im infected!

[gentle urchin]

It should be possible to device a function that converts a value through a fish-eye calculation

[gentle urchin]

Thats the fungus at work 😕 theres no hope

No cure found... day 571

[modern radish]

The FishEye Post Processing material for reference

[dire frost]

not much you can do honestly. im not familiar with PP effects but is there a way to simple the pixel distance from its actual position?

[dire frost]

im....i dont think i can do this no more....

anyway what do you think of bread?

[modern radish]

II was thinking perhaps I could hit using screen space instead in the BP, but I'm suspecting the PP must happen after

[dire frost]

you cant really do a hit scan on screen space since they are two different "planes" sort of speak

[gentle urchin]

You should be able to convert them tho

Xy screen -> through fisheye function equal to pp => xy world

[frosty berry]

Wired it up and get my message when it hits something, but never prints if projectile goes off in the distance. I have a LifeSpan value on the actor, so it is not 0 (forever).

[dire frost]

oh yeah for sure. i thought he meant to do a hit scan that starts from the screen and ends in the game world

[dire frost]

are you sure it's dying? try to print "remaining life" on tick

[frosty berry]

got it

trying to figure out why my projectile has a decent life shooting in one direction, but almost imeediately dies in another and there is no collision.

[lunar sleet]

That you know of

[frosty berry]

true

[modern radish]

Cool, thanks. I should see if it's possible to do that same math in the Blueprint then

[gentle urchin]

You may need to inspect the gradient

[frosty berry]

I have a "cast to" for the thing hit and if cast fails, it prints "hit something" and that never prints....so figured it may not be hitting anything

[modern radish]

Yeah it uses this custom radial gradient function, might be hard to imitate in BP

[gentle urchin]

You could also get away with dome map range clamped after figuring out the lin/max values i think...

maybe...

[lunar sleet]

And what prints if the cast succeeds?

[dire frost]

why are you casting at all?? just check if the actor reference equals to "nothing"

[modern radish]

what is a dome map range 😄

[dire frost]

actually why cast at all lol. if it hit something it hit something

[frosty berry]

hit thing 1

[lunar sleet]

You’re not going around telling people to == assets are you?

[gentle urchin]

Some* 😂

[frosty berry]

only have a few things that can be hit, so casting to get to some methods of that actor to do things.

[modern radish]

oh sure, sorry lol

[dire frost]

what if i am...? 🫢

[lunar sleet]

Is that printing when you get the odd behaviour?

[lunar sleet]

We’re here to deter bad habits not encourage them 😀

[dire frost]

sounds like a job for interfaces tbh

[frosty berry]

no

[dire frost]

how is that a bad habit?

isnt it the same thing as == nullptr?

[gentle urchin]

If it can only hit and damage child of some base class, then interface doesnt make to mich sense ^^

[dire frost]

oh wait yeah unreal has a isValid

my bad

dont mind me

[gentle urchin]

Fungus

[dire frost]

i've been spoiled with c# for way too long lel

[lunar sleet]

Then check if anything else can drop the bullet’s health

[lunar sleet]

Cast basically includes an isValid check and lets you access that actor’s insides

You also don’t want to check against assets because what you’re looking for is an instance of the object

[dire frost]

yeah but casts are expensive
readers added context

that's a lie

[lunar sleet]

They’re usually not that expensive tbh, it’s just something most tutorials makers peddle.

[zealous moth]

yup

or tick being bad

[dire frost]

well they are not as bad as the alternatives
(fan fact: interfaces are as slow as casts)

[zealous moth]

they are?

[fair sun]

Hi, I'm having trouble understanding collision and when hit events are generated inside unreal. I made a scene with 2 skeletal meshes A with collision as on picture, I then have 4 scenarios:

• An actor B1 thrown into a scene with InterpToMovement (generates hit events)
• The same actor B2 grabbed with a physics handle with simulate physics enabled (collides but doesn't generate hit event
• Actor B3 attached using AttachActorToActor to my pawn (doesn't collide nor generate hit events)
• Component C attached to the camera of my actor (doesn't collide nor generate hit events)

Why doesn't hit event fire for the last 3 scenarios? How do I attach an actor to an actor so that it generates hit events?

I'm attaching an image with collision setup + a video that shows the problem

[dire frost]

under the hood unreal just checks if the actor has the same UClass as the one casting against. which is O(n) cause it loops for all UClasses. same thing happens for interfaces

[frosty berry]

doing that now. and finding that all of my turrets have spots where the projectile "dies" faster in certain directions that others. Ugh! And none of them show any collision....
And I was so close to finishing this funtionality. doh!

[modern radish]

it might be a bit more than I can chew 😄

[dire frost]

btw dont let O(n) scare you. UClass are just integers and comparing ints is one of the lightest tasks you can ever do

[lunar sleet]

Smells like an issue with how you’ve coded the health drop

[gentle urchin]

Code smell

You never made smelly code ?

[lunar sleet]

@zealous moth ‘s GPU is backed all the way up from those

[frosty berry]

I am simply using the "Event Hit" to handle damage apply and then the EventDestroyed fires when projectile is gone. Using default projectile movement and actor lifespan. No other stuff in there.

[lunar sleet]

Show the code

[hearty sand]

bring back toilet pictures

[frosty berry]

Event hit string when it hits something followed by the destroyed print, or just the destroyed print.

[lunar sleet]

No I didn’t mean just show spaghetti, I mean show the damage portion

[frosty berry]

as in where I apply the damage to the hit target? Thats just it, at certains firing angles, the projectile just dies, no hit.

[lunar sleet]

Oh

Does the event destroy print ?

Or just nothing

[frosty berry]

yes, always. Either after lifespan on certain angles, or after a hit. Or very quickly after shot with no hit.

[lunar sleet]

Search all calls to destroy the actor

And also how are you spawning it

Are you making sure it can’t collide with the turret and it’s set to spawn anyways ignore collisions?

[frosty berry]

I only have a destroy actor (on projectile) after a hit. Otherwise it appears to "self destroy" at end of life.
Set to spawn, always ignore.

[dry lynx]

Hi everyone, is there any way to save diferent variables without saving everything at the same time? Like for example a slot for every diferent type of variable you want to save. Right now everytime I save the game I need to save all the variables that has been saved already.

[lunar sleet]

Do you have ignore actor while moving set on both the turret and the projectile after spawning it? I’ve seen Event Hit fail to register if the velocity is high enough and the fps is lower than 120

[dry lynx]

Can you like add a variable into the save game without needing to save everything and get overrided?

[frosty berry]

let me look!
here is what happens, first shot takes abot 10 seconds to show "destroyed" when I aim down almost instant.

[trim matrix]

what's the default lifetime set to?

[frosty berry]

10

[trim matrix]

what's the issue again?

it collides with ur player or whatever when it gets destroyed sooner

[barren dove]

here's a theory

when you ADS you are moving your camera, and the projectiles are set to collide with the camera(?)

so when ADS'd in you're just shooting the back of the camera which is right against your guns, which is why its despawning

[lunar sleet]

Yeah I hadn’t considered that

[faint pasture]

Draw debug sphere at hit location

remember tho, projectile movement component has its own hit events too

honestly I don't think it's very good, I'd make your own. It's simple.

Just make a component that does a line trace every frame and doesn't rely on having collision

[steady night]

hey if i have a "player Commponent" and wanna overrite whats inside with another "player" Commponenet" how would i do that

cuz in this case its replacing the commponent allthogether

[faint pasture]

Component

[steady night]

ideas ?

[faint pasture]

Temporary or permanent?

[barren dove]

I dont know what you mean by "overwrite" and "replace"

[faint pasture]

What are you doing here

[steady night]

its for my save/load system

[barren dove]

to me overwrite and replace are the same thing

[steady night]

well no

replacing is replcing to anoter actor basicly

overwite is keeping actor just replacing variables

basicly

[faint pasture]

Yeah you just want to save and load the state of that component, got it. I haven't done much with saving state of components directly, but you can always just copy the data into your savegame object. Would be a pain in the ass if you got a lot of data in it.

[barren dove]

I dont know if this helps, but what I am doing is setting the variables on the actor when I spawn it then using the construction script within that actor to create all his components/guns/etc.
If I need to update something I just update the table that contains all the variables then kill/spawn the actor again

its probably heavier performance wise but I dont do it often and bottlenecks all the calls and data through one system I can easily change rather than doing all sorts of callbacks and stuff

[faint pasture]

https://www.tomlooman.com/unreal-engine-cpp-save-system/
This looks to be the slickest way to do it without having to replicate all the components data in the savegame class

[frigid plume]

Hi, why i can't see weaponActor in my character?

[barren dove]

check expose on spawn(?)

[frigid plume]

same, nothing changed

[barren dove]

hm, I'm not sure then, sorry I'm still pretty new, you may have to set it to be instance editable, compile, then compile the other side for it to appear, thats typically how it goes for me

[lunar sleet]

Maybe explain what you mean by “see weapon actor”

[barren dove]

oh if you aren't setting a default, there's also a hidden dropdown in your variables area for "override" it may be in there

[frigid plume]

i want to set value of weaponActor at character

[steady night]

@faint pasture yeah thats the problem i got 6 different components with loads of data <.< would be really tedious work to do each one seperetly

[frigid plume]

all variables in the defaults category

[lunar sleet]

You seem to have a component WeaponActor in it

[frigid plume]

That was for a little test, I'll delete it

when game started, i can set at runtime

[frosty berry]

no true ADS.

[barren dove]

in that case i'd do a printout of location just before destroy actor and start hamfisting my way through it XD

[frosty berry]

and no performance issues there? (unless that is what projectile movement is doing)

[barren dove]

actually a faster way would probably be outputting your sphere trace/impact event and printing out the name of what it hit

[frosty berry]

THis is shooting in the direction that the projectile "dies" the fastest. No hit though.

[daring fractal]

Whats good people?
Not sure if this is the right chat for my question or not, but I've recently started back up on making a game trying to clean up my title screen

I've been trying to make a press to start screen to bring up the main menu, but is there a way to set focus to the screen/button and and only click or press the button once

The initial double click in window kinda feels janky

[dire frost]

Forcing your window to be focused isn't something you can do in unreal by default. Maybe with some C++ wizardry but I doubt that cause that would be a security concern for windows

[trim matrix]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Focus/SetFocustoGameViewport/

isn't this the node?

[grim sand]

If I spawn a character pawn at runtime, will the predefined controller of that character pawn also spawn and attach itself? Or is this something I need to do manually?

[daring fractal]

That's what I thought but it wouldn't run smoothly for some reason

Even umg setup is a bit buggy at launch but after everything runs smoothly

[steady night]

what could this be reffering to ?

[barren dove]

hm, so no impact event but its despawning? thats /weird/
doesn't look like a math issue from going from Xyz positive to negative either

[dire frost]

iirc you cannot send arrays in multiplayer

[frosty berry]

exactly, that is why I am so ... at a loss.

[steady night]

@dire frost what really 😮

[dire frost]

i remember seeing that in #multiplayer but im not sure.
but it does make sense imo

[faint pasture]

How do you think the built-in projectile movement works?

Anything that moves does so on tick or something like it

[steady night]

hmm

[frosty berry]

thats what I thought. May try my own then.

I had posted a few days back about my enemies not being affected when shot on top, but it turns out my projectiles arent making it far enough to hit them.

[dire frost]

ok just double checked. you cant send arrays, maps and sets in multiplayer

[steady night]

sets * ?

[dire frost]

an alternative would be to loop through the array and send the actor references via a reliable event

[frosty berry]

added a line trace and it shows now hit (green box) and goes onward...

[steady night]

@dire frostaye altho this is a save function locally

[dire frost]

oh why did you put it as a client event then?

[dry lynx]

Hi everyone, I will ask again In case someone knows this. is there any way to save diferent variables without saving everything at the same time? Can you like add a variable into the save game without needing to save everything and get overrided? Or maybe a slot for every diferent type of variable you want to save. Right now everytime I save the game I need to save all the variables that has been saved already.

[steady night]

@dire frost just tried stuff

[dire frost]

imagine arrays but like faster when it comes to removing/adding stuff but it only contains unique elements

[rich pollen]

this could not be a more simple request for ue5

and yet

feel like im being driven insane by this stupid thing

[thin panther]

You can arrays

[edgy ingot]

Maps you cant but arrays you can? There is event fast array serializer for mp i think

[thin panther]

Yeah the common workaround if you need to replicate a map is to have an array of structs, where the struct has your key and value

[gilded venture]

circling back to this-- looking for a way to automatically loop through all the variables in a given actor. any existing nodes or ways of doing so?

[thin panther]

In c++ there is

But it's not BP exposed

[wild crater]

I have changed the name of an enum in BP and submitted it. Now my colleagues have compile errors for that type. I know in c++ you have to use core redirects for this but in BP a simple name change breaks all the uses of an enum???

[thin panther]

Welcome to the bp enum and struct curse

Declaring them in c++ is what you want

[wild crater]

Yea but I joined a huge bp project. So porting anything to cpp is a pain

But I guess I could do it and use core redirects... See if that works

[thin panther]

Sounds like it was doomed from the start

[edgy ingot]

It is what it is

[wild crater]

Bps are awesome but they have some huge flaws my god...

[edgy ingot]

I give up making my old project all nice because its pure bp

[dire frost]

not sure about bp but for cpp you can only send an array with a limited size and you could potentially reserve the array unordered. i assumed epic thought that bps couldnt risk that but idk

[thin panther]

You can still absolutely replicate arrays

[dire frost]

that is a such a weird thing to do...what do you want to do exactly?

[thin panther]

It's not weird. There are some pretty useful usecases for it

Such as for auto saving systems

The property link in c++ is what you need for that one.

Nothing in BP does it

[dire frost]

yeah i thought bps were blocked from replicated arrays...

[thin panther]

It would not make sense if you couldn't, because the game state literally holds arrays and is replicated

[dire frost]

For that youd just serilize the whole actor instead of "looping" through each and every variable

[thin panther]

There are still cases where you may want the property link

For such a system. Granted the property link is more niche, but it is certainly useful

[dire frost]

Ah fair enough

[flat coral]

Out of curiosity, why does string "win" in this case and why is casting a name to a string a 'promotion'?

[thin panther]

Promoting just means a conversion

[dire frost]

Property link?

[thin panther]

Yeah. UClasses have a what's called a property link, which is basically an iterator for each FProperty

[dire frost]

oh TIL

[flat coral]

Also why is this legal but the reverse order of connecting the pins ISNT legal?

[edgy ingot]

Pretty sure u can compare strings

Just drag the pin and type ==

[flat coral]

that's how I got this

[edgy ingot]

U r trying to drag it into existing == . Try to drag the pink pin and type equal

You can deffinitly compare strings

[flat coral]

no I generated the existing == by doing what you describe, it drops the node in but refuses to connect it

I think you're supposed to use the stupid string-specific equality functions like java

[lofty rapids]

it just drops the node and disconnects it, you need to use string equality stuff

[dire frost]

string iirc has a "equals" node

[thin panther]

But yeah

Well technically it's on the ustruct which the UClass contains

[edgy ingot]

Thats what i meant tho. Use the string comparsion function

[rich pollen]

do spline meshes not work right on character blueprints?? it works right on an actor

[wild crater]

Could you elaborate on this? Does this only apply to renaming stuff? Or are there more annoying aspects to it?

[lofty rapids]

you should be able to see where it is ?

[sand bloom]

call me crazy but this does not look like infinite loop code

it's barely doing anything

I was just prototyping some stuff

a delay and a function where I set two variables lol

[wild crater]

That's a delay of -1?

What does that even do?

[sand bloom]

yeah but i did try it without just incase

oh yeah I did a delay of one frame to ensure everything works

[lofty rapids]

you don't have a loop anywhere else ?

weird it would say that about that i don't see it

[wild crater]

Can you break it and look at the BP call stack?

[sand bloom]

No this is all that is called from beginplay i'm super confused

wait it only occurs when I jump, but how is that related to beginplay huh

    Function /Game/Blueprints/Character/PlatformerMovement.PlatformerMovement_C:OnInterrupted_990860E245213C217FCE9BBD7D0F69BB
    Function /Game/Blueprints/Character/PlatformerMovement.PlatformerMovement_C:ExecuteUbergraph_PlatformerMovement

[frosty berry]

Rolled my own projectile movement without line trace/collsion at the moment just to get the ball moving.
Green dot is new projectile way out and the debug spheres show where the original porojectile was getting terminated.

[sand bloom]

I think it may be showing the wrong thing

[edgy ingot]

Show your jump function

[sand bloom]

okay yeah that's 100% what it did

[frosty berry]

Should the movement component just do the moving and the projectile check line trace every tick or the movement component do it all? And if so, can the component talk back to its parent to fire off a Hit event?

[sand bloom]

because i found a silly thing in my jump just now

and it works fine now

the beginplay just threw me off

because that's not where my issue was lol

so it's all good now lmao

[high frost]

some blueprint nodes (Listen for Gameplay Messages to be specific) disappear from my blueprint after restarting the project even though I'm sure I saved it properly. What might I be doing wrong here?

[gilded venture]

Specifically, I'm implementing my dialogue system. It pulls strings from CSVs, and I'm trying to add the ability to parse variable adjustments from the CSVs as well. For example, you talk to an NPC, a quest value goes up

How does it know what quest value to go up? It's listed in the CSV. So we need to be able to find the right key (which is in the CSV) in the list of variables

[random pulsar]

I set up the village stomach and i need somehow to decrease a small value from the progress bar ,and when player picks up some meat i need to add a value to the stomach can someone explain how can i write this?

how do i need to connect the max stomach and the current stomach?

[faint pasture]

What i mean is you don't need collisions at all

Tick -> line trace -> did it hit? -> yes -> ok do stuff

[barren dove]

hey Ilajo, you need to decide where to store the variable
I suggest some sort of pickup event on overlap with the meat, then you'd just have that event drive set -> variable, and the bar would be set as a percentage from max meat to current meat

[lofty rapids]

CurrentStomache / MaxStomache

[random pulsar]

for me its hard to understand this way and i also dont want to waste yours time but is the price of 10 dolars ok to show me in voice channel how to make it?

nvm i found a video)

[neon burrow]

Hey guys i can't remember how i made this work last time,

i have a ComboBox that has bunch of options that change the Anti Aliasing, the problem is i need the button to remember the selection,
so if you open the game first time it will show what the current Method used is.

[twilit jacinth]

How can I prevent my PickedUpActor from clipping through walls at high speed? Precisely when I "slam" it against the floor with very high velocity. I am grabbing the component through PhysyicsHandle and clamping its location on Tick to slightlyaboveGround level on Tick. Nothing seem to work

[edgy ingot]

Create an enum and set it and save it

[edgy ingot]

On game start get the enum value to display the current setting

[neon burrow]

thanks

[edgy ingot]

Did you get to save and load?

[plush hornet]

Hi all, just a quick question, how do I keep an object the same speed on a level sequence so it doesnt speed up or slow down?
Thanks

[edgy ingot]

The transform is relative to the timeline in sequence

Unless u r not driving it from sequence timeline

[neon burrow]

well i haven't touch the project since the save and load thing, it works just needs polish... polish ... andddd more polish

[edgy ingot]

Gameplay first imo

Polishing can come later

Still working on the horror game?

[neon burrow]

not sure, i have mixed feeling about what i want to make

[edgy ingot]

Very common dilema

[neon burrow]

kinda feels like overpopulation of horror games ( nowadays )

[edgy ingot]

My opinion is you should come to terms with what you want to make

And stick with it till the end

Dont make something big , start small

[neon burrow]

yeah pretty sure one of the bigest mistakes is working on something but never release it.

[plush hornet]

Little lost on what you mean. Im using a level sequencer. Also there is a relative function under the transform node but i dont believe thats what you meant.

[edgy ingot]

Thats not what i meant, i mean did you move the object using the sequencer?

[plush hornet]

yes

[edgy ingot]

I have no idea then because it should move relative to the timeline. If you have it on X position at 2 second it should be in that position in 2 seconds time

[plush hornet]

What i want is to create a loop where it moves at the same speed from beggining to end

[edgy ingot]

Then play looping sequence

And make sure to use linear for the transform

[plush hornet]

What it does normally is at the start of the sequence is speed up then slow down near the end

[edgy ingot]

Yes they are ease in ease out by default

If u want to make it linear, select your key frames and hit 2 or 4 i cant remember

But u want the triangle icon

[vivid spire]

Is it recommended to make your own state machine that is gameplay logic based instead of animation based? I saw on the asset store there were two somewhat popular ones, but one was 150 the other was 300. Right now I'm at the early stages and I currently have an object that has 3 (technically 4) states that it can be in and I'm not sure if I am doing it correctly since I am basically checking to see what state it's in when it does something. However I can see later on that my project might have objects with a bit more.

[plush hornet]

Yes you just highlight all the frames, Right click and choos linear. Thanks👍

[frosty berry]

Think I am close to getting my custom projectile movement working, but hit a rookie snag. My projectile base class has an Explode custom event. I am trying to call it from the Child BP "laser". When the movement has a "hit" it calls the base class Explode, but it never fires on the child. (breakpoints show it fires on the base class/parent). What might I have missed?

[neon burrow]

okay i tried making it, and it looks like this.. from short testing seems to be working, let me know if i did something wrong @edgy ingot

[edgy ingot]

Only way is to test it

If i can work things out w.o testing i wouldnt have to deal with debugging

[neon burrow]

yeah no it works, just asked if maybe i should change something

[edgy ingot]

Looks ok from here, assuming the save settings r set

Nah looks allrite

[neon burrow]

alright thanks :)

[grim sand]

I have been running into the issue where if I open up the gameplay debugger tool through the command line at runtime, the engine stops printing strings onto the screen. There are also no print strings on subsequent closing and opening of the engine. Anyone happen to know what causes this?

[frosty berry]

thanks all... got my custom projectile movement working and it solved my early termination issues. Means I missed something in the OOB Projectile Movement...but all is good.

[vivid spire]

I just want to bumb this

[neon burrow]

you mean a animation state machine?

there is the free... locomotion project ( made by a guy who got hired by epic )

[vivid spire]

Isn't that basically just for animation though? Like for instance, in my case I might have a button that is active, deactive and destroyed, each having their own logic, since they aren't really animations, would the animation state machine allow me to put its own gameplay code in it?

[neon burrow]

i mean from what i know it's only used for animations..

[edgy ingot]

Anim instance just read variable from its owner to drive the animation

You should not do any logic in the anim instance

For something like a button or switch you dont even need anim blueprint

[vivid spire]

Ah yeah, that doesn't really work for me since another object in my game doesn't have any animations, it is just a physics object that also has 4 states

[neon burrow]

this is one of the best project u can learn from ( for anim state machine )

[edgy ingot]

Nah, for those who can dechiper it. They said its spaghetti

[neon burrow]

well spaghetti worth enough to get hired

[vivid spire]

Yeah, that's what I thought. I didn't say I wanted to use a anim blueprint, I was wondering if there was another way to deal with finite state machines for logic or would it just be easier to use some asset on the marketplace

[neon burrow]

i can't read it lmao

[edgy ingot]

Sure but still spaghetti. He stop developing it too

Its good to have movement going

But to edit or add is not easy

[vivid spire]

Currently on that physics object, I have 4 variables that are basically branched to check which state it is in

[edgy ingot]

No idea what you want to do

What fancy things do you need for a switch

[neon burrow]

yeah i once tried adding metahuman, and change some stuff, and instantly gave up and decided it would be easier to make it from scratch lol

[edgy ingot]

I find making animation to appear fluid is not an easy task

[neon burrow]

yeah, well depends how epic you want the movement to look

[edgy ingot]

Rdrd epic

[neon burrow]

made by one of the biggest studios

for a single guy it's impressive

[edgy ingot]

Yea i got to settle with what i can muster 😭

[edgy ingot]

I used als for my old ongoing proj

Not saying its bad but for learning maybe not the best source

The als it self is a gift to the community imo

[neon burrow]

yeah the unreal marketplace is one of the best things... the amounts of free content is "unreal".... haha get it ? ........

[vivid spire]

For the physics object:
State 1 (Spawned State): It falls as a physics object until it hits ground then goes to state 2, player shouldn't be able to interact with the object
State 2 (Waiting State): The object waits on the ground for a few seconds, player walk up and kick it around or whatever, after a few seconds the object goes into state 3
State 3 (Adjusting state): The object goes to a hovering position, goes to state 4 after adjusting to the position
State 4 (Hovering state): The object rotates and hovers, the player can pick the object up

Thats what I 'm trying to do, isn't that a finite state machine? Is there an easier way to do this other than 5 booleans and if any time the player walks up to it to check each boolean to see what state the object is in

Nothing is animation based

[edgy ingot]

Not sure what animation based actually mean. If thats an actual thing, well i just didnt tap this kind of subject

Afaik in normal bp you cant do state machine? Maybe you can use behavior tree i dunnoe.

[vivid spire]

I don't need an anim blueprint since it doesn't use any animations

[edgy ingot]

Yes but bp dont have finite state graph

Maybe theres plugin

[vivid spire]

So it is better to just get one of those assets then?

Since that was the original question

[edgy ingot]

What asset

I dont know any plugin

If it cost 300 i would pass anyway

[vivid spire]

Yeah

Ok thanks

[edgy ingot]

Anything you describe above doesnt seems to require state machine to work

But maybe i dont know better

If an object needs to be in certain state i would just use enum

[neon burrow]

before you mentioned it, i have not only never seen it done.. but not even imagined it being done.

[vivid spire]

The issue is, when I need to go from one state to another, there is a situation where it can go from state 4 to 2

[neon burrow]

in unreal sometimes there is multiple ways of doing 1 thing.. but this ain't it

[edgy ingot]

Yea i dont c the problem. I would just use enum

Nice 👍

[neon burrow]

kinda reminds me of that graph
CD projekt showed on how the options work

[edgy ingot]

I just checked it out

Thst looks neat

[neon burrow]

looks quite " clever" and fun to use

[vivid spire]

Yeah I somehow didn't see that, but I didn't look that hard since I basically asked here first, since to me a state machine seemed like something that would be built in

[edgy ingot]

Still too expensive for me

[vivid spire]

Free?

[neon burrow]

Limited functionality

[neon burrow]

" you are alowed to make a single state machine "

just noticed it's per user

[lunar sleet]

Get that super expensive UE5 Coro plugin

[edgy ingot]

Mb, when i see a price tag i tend to forget about the free trial

Yup

I stand mistaken

[vivid spire]

TBH, the free tier works for me, I don't need much validation which seems like most of the pro features since I'm a solo dev for a game that probably won't sell anyways, I'll just forget to plug something in anyways

[neon burrow]

The dream of an Indie dev

" full version for free "

random thought
what if everyone here worked on a single game O_O

time to make gta 6

[lunar sleet]

The p4 merge would be a nightmare

[neon burrow]

github would shutdown ( if using github )

[lunar sleet]

Using GitHub with that large of a team?

[neon burrow]

well "as a joke"

if everyone did even a single thing ( asset or animation or audio or UI )
there would be a game

[gentle urchin]

Id make a component with states and transition rules

[vivid spire]

Isn't that... just a finite state machine?

[gentle urchin]

Yepp

I may have skipped a post where you asked for something else ?

[vivid spire]

Yeah, the original post was basically asking if there was a built in type of state machine I could use for logic or would have make my own/use a marketplace addon

Yes I know

[lunar sleet]

Glad we’re all on the same page

[neon burrow]

yep, making gta 6 as a team of 25K

[lunar sleet]

Minus all of us that would prefer not to work in a team

[dreamy mountain]

how do i make like a progress bar that goes down as a 'cooldown'

i have a delay in the dash mechanic which i want to show visually as the cooldown

[neon burrow]

possibly make that delay a value that gets subtracted

[dreamy mountain]

how?

i dont see any pins to connect to

[neon burrow]

when the delay function happens set a new value ( the value is the time the cooldown should take )
then possibly use something like a Tick event, to subtract the value

and then just connect that value to the "progress bar"

there is better ways of doing this pretty sure, but thats one way it could work

[dreamy mountain]

ive got a variable called dashcooldown

which is connected to the duration of delay

[edgy ingot]

Current cooldown / cooldown time = your progress bar percent

[dreamy mountain]

idk how id convert this into something like that tbh

dash cooldown is 2s

[ornate kraken]

Hello. Does someone know how I can get how stretched UVs from a hit Actor are to then stretch the brush size in that direction and make it appear normal.

[ornate kraken]

If you want a value that increases or decreases overtime I would recommend a timeline

[dreamy mountain]

how would i do them

[snow oasis]

Is there a way to reference the Skysphere in an Actor Blueprint? I'm casting a line trace and want to add it to an Array of things to be ignored.

[lunar sleet]

I mean, not gonna ask why you’re line tracing at the heavens, but it’s set to No Collision preset so either make it custom or trace on a channel it already ignores

[snow oasis]

I'm making a movement system where you look and click on something and smoothly lerp to that Position

It works fine when you click on the Environment but if you accidentally click outside of the playspace then SOMETIMES it will hit something and send you to something at X:0 Y:0 Z:0

[versed sun]

If distance between Current position and clicked position is < Threshold then
Move to new position
If not
dont move

[snow oasis]

That would work

Thanks.

[edgy ingot]

You should run queries and check if pathable

If not reachable then dont commit to the move

[versed sun]

and the Sky sphere is probably centered at 0,0,0

so if you cliked on that , then ignore

[edgy ingot]

Start by not using delay

In basic form, input dash should execute dash function which will then start a timer to decrement dash cooldown.

Your widget will just need to show the precentage of the cooldown which is currentdashcooldown / dashcooldown

[dreamy mountain]

i dont know how to decrement it tho

ive taken delay out, im guessing i put in a timer?

[edgy ingot]

Set looping timer of 0.01 sec. Which run a function that decrement the currentdashcooldown by 0.01

[neon burrow]

i meant keep the delay but before u do the delay SET a Value

[lunar sleet]

Delay is the wrong choice in 9/10 cases, best not to recommend it to new people who already use it because they think it works the way it sounds

[neon burrow]

in his case he needs the delay to just stop the exec from continuing for certain time.

but yeah there is better ways

[edgy ingot]

In his case he should get rid of the delay

[neon burrow]

without a delay

[edgy ingot]

Too many trash tutorials using delay

Especially in gameplay mechanic, why do you want to run somethings with pinky promise

[thin panther]

you never want a timer that low

tick is always preferred over that

[neon burrow]

fight fight fight

[edgy ingot]

Agree with you for performance wise. My small brain just dont know how to decrement without being frame dependent

Prob use delta time yeah

[thin panther]

instead of decrementing, come up with a stamina loss per second, and decrease stamina by that value * delta time :D

[lunar sleet]

and there’s the fallacy I was talking about. Delays won’t stop the timer or tick from ticking away, hence why it’s a terrible idea

[neon burrow]

true

[edgy ingot]

Awesome

[neon burrow]

so the best way to handle a cooldown timer

is to not have one 🤓

[lunar sleet]

Indeed, coroutines would be great but that’s a tad more advanced

[thin panther]

well that is a cooldown timer

for a cooldown timer it adapts slightly

idek where i read stamina from lmaoo

instead for cooldown you add the delta into a variable, and check if it's greater than your needed cooldown

[lunar sleet]

I wonder if the guy left the chat like 15mins ago 😂

[neon burrow]

he probs gave up on the entire project

turned the pc off

[lunar sleet]

So does a BT btw, don’t hate me for saying it lol

[neon burrow]

and went to sleep

[lunar sleet]

Delay?? Timers?? Corout… ah f this I’m outta here

[plush hornet]

Hi back again. How would i create a class i.e like an NPC class or enemy class?

Thanks

[lunar sleet]

New blueprint, character class or pawn or w/e

Profit

Next customer!

[dreamy mountain]

like fuck lol

[dreamy mountain]

im still trying, i havent a clue if im doing things right lol

[edgy ingot]

I would use character instead of pawn if you are making humanoid npc or enemy

[neon burrow]

just put a timer on screen and make the player count..

[dreamy mountain]

no lol

im not that mean

thats what i have and it looped indefintetly

[edgy ingot]

Dont know aboht doing things right. The fact that i see dash cooldown bool is already not what i would do

I would create a base class for skill

Each track their own state and timer

So when i need another skill to press i dont have to recreate the same thing over and over

[dreamy mountain]

its the only skill i have lol

[plush hornet]

How would I apply this to actors I have already?

[neon burrow]

will it be the only one ?

[dreamy mountain]

yes

[neon burrow]

then it should be fine

unless in future u want to expand

[dreamy mountain]

ill cross that bridge when it comes

i need to get a somewhat working version by friday

fir college

[neon burrow]

I prefer making stuff modular / customisable.... I hate redoing things

[dreamy mountain]

same but on a time limit, i can bare with it

[edgy ingot]

In the player graph it should be as simple as ActivateAbility. It doesnt need to know the current cooldown or doing the decrement

[dreamy mountain]

after friday, im making a different game then lol

Binding: Property ' /Script/UMG.ProgressBar:PercentDelegate ' on Widget ' ProgressBar_0 ': Member:GetPercent Has no return value, unable to bind. i get this

[lunar sleet]

You can hit File -> Reparent if you want

[neon burrow]

what are you applying?

[neon burrow]

u want to change your npc's to Pawn's?
or u have skeletal mesh or other

[edgy ingot]

Compile

Save

[dreamy mountain]

i did

thats what i get

[plush hornet]

I just want to have certain groups together for when i cast certain things I.E certain enemy groups/classes, NPCS, Interactive objects

[edgy ingot]

Try to return on false and cast failed

[edgy ingot]

Then have a base class

[dreamy mountain]

still fails

[plush hornet]

yeah thats what im after

[edgy ingot]

Npc player enemy friends can be MyGameCharacter

They all can inherit from the same base class

[neon burrow]

yeah make a child or something

[plush hornet]

how would i create that

[edgy ingot]

So whats stopping you? Right click new blueprint , choose character

[neon burrow]

just normal bp, and then right click and make a child

[plush hornet]

just add the said actor as a child to my npcs for example?

Is that enough?

[edgy ingot]

What actor

We talking about classes

If you already have existing class and its not character and thatd your base. You can reparent that as neo says

[plush hornet]

Say I have multiple NPCS and I want them to be in the NPC class so that if im in range of any of those NPCS I can speak to them for example

[edgy ingot]

The point here is to understand OOP

[dreamy mountain]

ok so remaking the function fixed it

[plush hornet]

whats that?

[dreamy mountain]

aaaand ue crashed

fuck

[neon burrow]

F

[dreamy mountain]

i dont think i saved either

fuuuck

[edgy ingot]

Im not good at explaining. You can google it and look up the concept of inheritance

[dreamy mountain]

oop is object oriented programming isnt it?

[edgy ingot]

Thats the abbreviation yes

[lunar sleet]

Source control, see pin in #ue5-general and set it up, the earlier the better

[neon burrow]

incredible

[plush hornet]

yep thats it

[neon burrow]

please rate my artstyle

[lunar sleet]

That could further branch up to one base class

[dreamy mountain]

i got it working

[plush hornet]

Thanks guys, couldnt find any videos for classes but Inheritance was what i was looking for🤗

[dreamy mountain]

its just a very like uhh

not smooth fill

[edgy ingot]

This is horirble and run in prepetuity

[dreamy mountain]

yeah ik its horrible but it works

[edgy ingot]

As for your smooth fill u run the logic every 0.1 sec thats not gonna be smooth

[neon burrow]

the good old"

if it works, don't fix it.

[dreamy mountain]

yeah i figured

[edgy ingot]

Do it on tick with delta time as cuppa suggest

[dreamy mountain]

exactly

[dreamy mountain]

how would i put it in?

[edgy ingot]

#blueprint message

[dreamy mountain]

i guessed here but idk

[loud tree]

Gross but it is viable

[edgy ingot]

No its in your tick

[edgy ingot]

Why is that?

[loud tree]

I just try to avoid tick like the plague, I know it's fine to run some things on it and I do, but I just try to make alternatives.

[neon burrow]

some stuff have to be run on a tick

[edgy ingot]

This is when you should run ticks

[dreamy mountain]

what would your alternative be?

[edgy ingot]

If something needs to be checked every tick, use it

[loud tree]

For cooldown? I came up with a formula that uses set timer by function to update the widget fill bar.

[edgy ingot]

Ppl avoid it because of youtube myth

[loud tree]

on a loop

[edgy ingot]

Timer with 0.01 is worse than tick

In terms of performance

[loud tree]

I just don't want to become reliant on it when there are alternatives.

[loud tree]

I don't use .01 lol

[edgy ingot]

Worse alternative?

[dreamy mountain]

it would also help i realized the bar fills up when the cooldown percent is 1 and below lol

whenever the cooldown is > 1, it doesnt fill shit

[loud tree]

you have to break it down into fractions/decimals. 1=100

[edgy ingot]

0.01 might not even be enough for smooth fill up bar

[loud tree]

Mines pretty smooth I'

[neon burrow]

make it a animation or something lol

[loud tree]

I'd say

[neon burrow]

that would make it smooth

[edgy ingot]

Whats the time?

[loud tree]

whatever time I set it to.

rn it incrementally increases

[edgy ingot]

Even 0.1 is not smooth

[dreamy mountain]

what is a delta second?

[edgy ingot]

We r talking about how to make smooth progress bar fill

[dreamy mountain]

like, im thinking, i have to do * or / to increase and decrease the time

but idk

[edgy ingot]

#blueprint message

@dreamy mountain read pls

[dreamy mountain]

it wont load

[neon burrow]

you would use delta time for something like a FPS counter

[dreamy mountain]

ah ok

well, ive got what feels like a decent time for the dash

with a visual cooldwon

so thanks

[edgy ingot]

Delta time is just time diff between last frame and current frame

[dreamy mountain]

ok

yeah, cooldown is 2.50~ seconds

with delta x2

1 - (delta x 2)

[edgy ingot]

?

[dreamy mountain]

the cooldown for the dash

[neon burrow]

space math

[dreamy mountain]

fr

now i need to actually make a level lol

oh btw

is there a random number node?

[neon burrow]

0 -1

[dreamy mountain]

there needs to be some halloween theme, so im just gonna throw in a cheap k-fee car jumpscare when a number = something random

just every tick

[neon burrow]

this i guess? xD

[dreamy mountain]

yeah could do lol

[versed sun]

Random Bool with Weight might be a good fit
Basicaly a % chance to be true

[edgy ingot]

If its an event that run once a while, just use timer

[dreamy mountain]

could do, yeah

[edgy ingot]

You use tick when you need something to happend asap. If you use timer with a small number, you might as well use ticks

[neon burrow]

" now i just need voice acting/ motion capture / animations / levels / assets / gameplay and other "
easy peazy i have 1.5 days left

[dreamy mountain]

fr

it just needs to be a basic game

its for a college project

first one of the course

its halloween themed

doesnt need to be extravagant with motion capture

[neon burrow]

downloads gta 5 source code and codes a new mission
then shows up to College with it

[dreamy mountain]

fr

[neon burrow]

by college u mean a UK college or like an American one or ?

[neon burrow]

go all the way out, and make a full blown triple AAA quality game

Until Dawn 2 or Detroit Become human

[dreamy mountain]

uk

as in mandatory further education college

[dreamy mountain]

i wish

[neon burrow]

yeah i went to UK collage too
went for IT rather than game dev

[dreamy mountain]

out of the whole class, im the only one really doing any game shit, theyre all doing more good models, im going for good gameplay

[dreamy mountain]

sounds fun

it was between those two for me tbh

[neon burrow]

i left after the first year lol

as its simple stuff, that i already knew and i didn't wanna spend 3 years re-learning the same stuff

but atleast you get a certificate

[neon burrow]

it it a solo project ? or a team effort

[dreamy mountain]

team effort but im the only one who really knows unreal

still in year one

the team im in, im on unreal, one kids on blender, ones on the game pitch and ones doing music

but the music kid hasnt been in

and everyones affected by bus strikes in the north east

[neon burrow]

ah, yeah i get you... i was also the only " knowledgeable one"

[dreamy mountain]

yeah

but when you bust out shit that wsnt hard to make but they dont know that and are impressed

love it lol

anyway, blueprint things

how would i make a ui element move down whenever i collect an item

i have a totalscore variable which goes up

i just dont know how to make the ui move

[neon burrow]

UI animation

[dreamy mountain]

ok

ill look into it tomorow

gtg

bye

[neon burrow]

bye

i have this simple slide animation that " slides" the "game saved" text
and then have it played in reverse

incredible animation skillz

[tawny patio]

Hey guys need help, here I have a begin overlap for my enemy. And on my player I have this hit box that will overlap with enemy and I want to ignore the collision of this box and only overlap with the player capsule.

[lunar sleet]

ok, so what's the issue? 🙂

btw, to avoid spaghetti streams like that, promote the return value to a variable and then just get it as many times as you need

[tawny patio]

It doesnt work, Is there a different way of ignoring collison of this box's collision with the enemy without interfering with the player collision with the enemy.

[lunar sleet]

yeah, you might need to change the object type and/or make a custom collision channel

[tawny patio]

oh custom collision

Is there any resource where I can learn this?

https://www.youtube.com/watch?v=QQvHZLB4CTU

I found this one seems very easy to do

[lunar sleet]

I mean it can still be tricky but technically not a difficult concept to learn, at least not the creating custom channels and object types part

[solemn basin]

Who is up for a math problem? I would like for the first 6 cards to be equal distance from the center of the hand like it is currently. But after 6, I would like for all the cards spacing to get less and have the far left and the newly added card stay in the same relative space.

[vast lion]

So not having CannotImplementInterfaceInBlueprint requires each class to implement the entire interface...?

[storm shale]

I recently opened a project and for some reason took forever to compile shaders, then once opened it was super slow and consuming drastically more memory than any other peoject. Anyone experienced smth similar?

I've opened the project many other times, it never takes so long to compile shaders or anything.

[snow oasis]

Would anyone be able to tell me why my Interface isnt working?

[uncut condor]

Hi, is it possible to play FlipBook in Widget?

[tawny patio]

You cant but if you want animated widget youd have to make a user interface material.

[tribal gazelle]

How can I use this node from inside a character component? I cannot create or paste it.

[edgy ingot]

You cant

Timeline needs world context afaik

So it doesnt work in component

[tribal gazelle]

Any work arounds or alternatives?

Like a flip flop?

[edgy ingot]

Whats flip flop got to do with timeline?

What do u want to do

If you want to level up, use 0 flip flop in your project

[tribal gazelle]

It's part of my flashlight code tbh idk what it does, copied it from my map asset example character

[edgy ingot]

You can move the timeline logic in the owner actor i suppose

[tribal gazelle]

Trying to avoid just that

Here is more of the code

[edgy ingot]

You cant run timer in component

That flip flop tho.
Use bool instead

What if you need to save states? Like if flashlight already on, you want to keep it that way when the player transition to new level

Thats not gonna happend with your flip flop because it alwahs remember its state

Not controllable

[tribal gazelle]

The state of the flashlight does not need to be saved. Although never thought of that before.

[edgy ingot]

Well when you do, you have to go back and redo the flip flop bit. I would just never use that node outside prototype

Its not just about saved. What if u want a cutscene and have everyone flashlight turned off?

[frosty heron]

You can , but need plugin

[uncut condor]

oh nice

it isn't free plugin, is it?

[frosty heron]

I used CSW

not free iiirc

[uncut condor]

how much

[frosty heron]

checking for you

8 dollars

[uncut condor]

what is its name

[frosty heron]

CSW Flipbook for Widgets

[uncut condor]

not bad i guess ..

[frosty heron]

8 dollar AUD so maybe 4-5 USD?

[uncut condor]

does it get constant update or it is stuck in time?

[lean compass]

how would i handle player hurt boxes in a fps game so i could make headshots do more damage and footshots do less etc

[frosty heron]

wdym

I never update it so I don't know. It served my purpose

but it seems to get patched all the way to 5.3

[frosty heron]

You simply check which bone you hit. You will have to setup physic assets for your FPS skeletal mesh

[uncut condor]

I'm watching a work around tutorial how to display flipbook in widget but it seems OVERLY complicated process

https://youtu.be/GFc0hGx8MOU?si=hHVnKckwjnnUSDQj

[lean compass]

thanks bro

[tribal gazelle]

@edgy ingot look better? This works also.

[frosty heron]

For me, preferably less spaghetti

[tribal gazelle]

Yeah I am yet to clean everything up, I like to get it working first, then optimize.

[frosty heron]

@tribal gazelle

[frosty heron]

not complicated but you have to do the legwork on your own

with the plugin, there is already function to play, pause, resume, change playbackspeed, etc

[uncut condor]

however, will what is in the tutorial do the job?

[frosty heron]

Didn't really finish it but I don't see why not

do the job as in it will play the flipbook

[tribal gazelle]

Classy

[frosty heron]

to do other function you will have to write it your self

[elder lodge]

I have a component that adds itself to a manager's Array on Begin and removes itself at End.
Is there a significant overhead to changing it to a Map in order to have it be O(1) instead of O(n)?

Is there some unreal node that would do array removal more efficiently?

Or handles this general model, since I imagine it comes up quite often

[dawn gazelle]

I don't think this is doing what you think it is doing. You appear to be saving a copy of the array in the component, adding the owner to that copy of the array and removing the owner from the copy of the array when the component ends play. If the below is a reference to the actual array you want to modify, that's what you should be adding and removing from.

As for your question, Adriel was doing some testing with iterating over arrays, maps and sets here that you can take a look at: #blueprint message

[elder lodge]

Really, it's not a reference to the Manager's array? I assumed since I'm getting that same object it would be a reference.

It seems to work, at least, in the editor when playing

and checking the manager's array

and destroying actors

[dawn gazelle]

It would contain the same things at the time that you first set it, but it would be its own array being stored in the component.

[edgy ingot]

Why is your end play didnt remove the array from the manager?

[elder lodge]

Truly the manager had the array working a second ago and now it's not 😅 I have no idea what I changed

[elder lodge]

The manager's the only one who's supposed to have a reference to the array

[edgy ingot]

I mean dont you want to gwt your manager-> emmiter array then remove that one?

[elder lodge]

So is the solution here to store the game mode instead of the array?
I'm just trying to have it not duplicate the same Cast and Game Mode bit for the End Play on removal, unless that's the only way

[edgy ingot]

Instead working with 2 instances of diff array

[elder lodge]

I was hoping it to be references to one array; as Datura points out I'm accidentally creating a second one.

[dawn gazelle]

All you should need to do is this...

That is then at least referencing the same array (the manager's?) to add and remove from.

[elder lodge]

Truly that's what I had it like before, but I wanted to unlink the two events for ??aesthetic?? reasons

Also because that'd require a pure cast yeah?

and i was warned off overusing pure casts

[edgy ingot]

Who warned you? Lol

[dawn gazelle]

You don't have to use a pure cast. In fact, in this case you probably shouldn't as you're doing an isvalid check anyway which is what an impure cast does.
You can also have the cast again on the endplay if you want to have it split up and looking more aesthetic (and actually slightly better practice to do anyway, it's bad to cross execution lines)

[uncut condor]

Hi question regard Flipbook node in material editor, the node displays the sprite sheet depends on the number of rows and columns but is when the sprite is not squar meaning 2 by 2, 4 by 4, or 6 by 6 number of sprites there will be a missing frame during displaying the sprite sheet

my question is there a way to fill the gap between the frames without having updating the sprite sheet?

[edgy ingot]

I see you are trying to use material as a mean to display your flipbook in widget

[uncut condor]

yes i'm giving it a try

[edgy ingot]

Not sure if u can pause, change playback speed etc

Tbh for me that 5 bucks was money well spend

Cuz i can actually work with actuak flip book

[uncut condor]

it is not about the price ... i don't mind even of it is 100 bucks. it is about what is the relaybitiy of the plugin

[elder lodge]

#blueprint message

[edgy ingot]

Chang frame, rate etc

[uncut condor]

wait im coming back

[edgy ingot]

I agree with not everything should be impure

But has its place

[elder lodge]

I see people mentioning events vs functions
is that like saying I could alternatively have my object ping the gravity manager to add to their list instead of having the object do it itself?

[edgy ingot]

You can broadcast using event when the comp is created

But if the manager not guaranteed to exist then you want to rethink your design

[uncut condor]

yeah what im saying is that a third party plugin is not bad but sometimes isn't good either. how do I know the developer will continue supporting the plugin?

[elder lodge]

Yeah, that's what the delay is for, though it does feel like a hacky move
not sure what the more robust solution is

[uncut condor]

I will keep it as a last option for now

Does plugin allow the flipbook to interact with blurprint normally without any issues?

I'm really REALLY surprised by epic how they neglect such simple thing .... strange

[frosty heron]

if event delegate doesn't solve the issue, I would use repeating timer instead of delay

at least i know at some point it will be set

[serene cave]

Hey, does anyone happen to know if SetRestCollection for Geometry Collections is working in BP right now? I'm dynamically creating a Geometry Collection from BP but calling SetRestCollection doesn't appear to actually do anything. My Geometry Collection is essentially empty

[tribal gazelle]

How can I posses a SpawnActorOfClass?

I want to leave my current actor and become a new one

[edgy ingot]

Casto to pawn or character

Get player controller , posses. Use the cast value as the target

[dire frost]

^ just make sure the spawned actor is inheriting from pawn

[tribal gazelle]

What is best way to replicate in a widget cast? I use GetOwner (Actor Component) for other casts in components, I just don't have that option in a widget. What should I do?

[frosty heron]

Don't think you understand replication

widget just read the current health value from the character

it doesn't need to care about setting or replicating the health value

[tribal gazelle]

Wouldn't GetPlayerCharacter only work for player index 0?

And not others?

[frosty heron]

yea that's not what you should use in multiplayer setting

like ever

Instead what you want is probably to get the owner of the widget

Get Owning Player -> Get Pawn -> Cast to Your Character -> Get health

[tribal gazelle]

From what I've learned I can use GetOwner inside components to get the replicted actor, am I wrong?

[frosty heron]

You get owner to get the owner of the widget

as simple as that

wether it's replicated or not is another matter

[tribal gazelle]

Oh ok thanks

[frosty heron]

Get player controller / character with index will return different results based on who called it (Server/Dedicated/Client)

[shell breach]

hi can anyone tell me the reason why in BP editor Y and Z axis swapped

[dire frost]

it isnt?

z is up and y is right

just like tim intended

[shell breach]

nope not always. For example look at box extends for Box component

so many times I have to write extra lines to swap Y with Z in runtime

I guess the reason is unreal devs decided to make every local (relative) stuff right coordinate system rather left for some reason

[ruby dew]

is there an audio input equivalent for this node? Can't seem to figure out how to change audio input device via blueprints

[wild crater]

Is it possible to change the name of the "time" axis in a float curve?

[light citrus]

I have UCommonActivatableWidget as HUD
When I press left click nothing happens, it used to work with regular widget
in log I see

LogViewport: Display: Viewport MouseCaptureMode Changed, CapturePermanently_IncludingInitialMouseDown -> NoCapture
Any idea what i am missing?

It's nohittestable too

[heavy lion]

I have created a data table. But the toolbar buttons along the top are missing. Anyone seen this before?

Weird. Created a new one and it was fine....

[neon burrow]

reset the layeout

[vast lion]

How would I make an editor tool that generates new assets?

[spark steppe]

with C++

[wild crater]

Is it possible to add a "tab" to a print string in blueprints?

[edgy ingot]

Tab?

Try to elaborate

[wild crater]

just tab, you know from tabs and spaces

[edgy ingot]

No i have no idea

[vast lion]

Why can't I construct an object of MaterialInstanceConstantFactoryNew?

[edgy ingot]

You mean new line?

[vast lion]

BP throws error "cannot construct an object of that type"

[wild crater]

no

[edgy ingot]

Try cpp to create asset. I dont think you can do that in bp. Im using plugin that create material for me. Its done in cpp

[vast lion]

Hmm

Ok

[dire frost]

just press space 4 times?

[wild crater]

No it's about aligning multiple lines of text where the first part is different

[dire frost]

ah yeah strings doesnt have that supported

you might need to implement that yourself (or maybe there's a plugin that does that for you in the marketplace?idk)

[gentle urchin]

You could 'force' each section oof the string to be a specific length...

not sure if displayed string is uniformed text tho. doubt it

[tough jasper]

How would I go about making an input system that only affects my actor's rotation based on my input instead of movement and rotation? I've already implemented a button to toggle between the two modes, but I don't understand nodes enough to get my desired result.

I'm trying to modify the base 3rdperson movement set up in UE4 if that helps any.

[surreal peak]

UE4? :<

Can you try to explain further what is currently happening and what you want to happen?
Rotation only changing by Input is kinda just that, modify Rotation from your Input.

[tough jasper]

Basically I'm trying to achieve an effect similar to the "hold still" control in plate up. You move normally with WASD, but if you press space WASD only affect character rotation and don't add any movement.

Just unsure of what node I would need to use to do that

[surreal peak]

I don't think there is a simple node for that. You will need to set your own boolean that determines the mode.
And then where WASD is currently applying MovementInput, stop that via the boolean with a branch and perform the rotation part instead.

[tough jasper]

Yeah I've got that all set up, but the setactorrotation doesn't seem to be the right node, or I'm linking stuff together incorrectly.

[surreal peak]

Nothing is changing your ControlRotation here

You need to math out the rotation for your char

Depending on the AxisValues fo the two Axis Events

And fwiw the current Camera Rotation, which could be the ControlRotation if you use that

Just setting Character rotation to Control Rotation won't do much

[tough jasper]

It's gonna be a topdown game, so I don't think I'll be able to use camera rotation to determine it

I'll do some more googling and see if i can figure it out

[trim matrix]

You can use the Atan2 (Degrees) node to get the Yaw rotation for your character. For the X, Y of it plug in MoveForward's Axis and MoveRight's Axis respectively

[tough jasper]

And what do I use to turn that into a rotation value to plug into setrotation?

[trim matrix]

It outputs a float that is ur Yaw

use it in the make rotator node

and plug that into the setrotation

[tough jasper]

Ah so just duplicate the main shit and replace the first few nodes

[trim matrix]

MakeRotator(Z (Yaw) = Atan2(X=MF.Axis, Y=MR.Axis))

[frosty heron]

@trim matrix what happend to your pfp?"

[tough jasper]

Yeah no i realized that immediately

[trim matrix]

idk bud

[tough jasper]

Just needed the one node. It's 3am. My apologies

Ty though, that achieved exactly what i was going for

[trim matrix]

https://en.m.wikipedia.org/wiki/Atan2

The movement axis combined together make up the "ray"

Hi, I'm having trouble understanding collision and when hit events are generated inside unreal. I made a scene with 2 skeletal meshes A with collision as on picture, I then have 4 scenarios:

• An actor B1 thrown into a scene with InterpToMovement (generates hit events)
• The same actor B2 grabbed with a physics handle with simulate physics enabled (collides but doesn't generate hit event
• Actor B3 attached using AttachActorToActor to my pawn (doesn't collide nor generate hit events)
• Component C attached to the camera of my actor (doesn't collide nor generate hit events)

Why doesn't hit event fire for the last 3 scenarios? How do I attach an actor to an actor so that it generates hit events?

I'm attaching an image with collision setup + a video that shows the problem

[wild crater]

Nah, but that's okay. It would've been nice but not important

[trim matrix]

I think you just use the tab key...

neither does \n work there, u gotta do shift+enter

[keen hedge]

What's the easiest way to move root component when moving attached (child) component? NOT vice versa which is the default 😄

[versed sun]

Like when driving a car , the car moves to where the driver goes?

[dreamy mountain]

is it possible to use a variables value within a single text box along with other text?

so for a score, instead of two text boxes next to each other, can i do like Total Score: {totalScore}?

[tight pollen]

someone can help? #umg

[clear sierra]

use FormatText it can use parameters

[crystal crown]

My BP is still ticking on begin play even tho i have start with tick disabled🤔

[coarse grove]

Hello, Im with a trouble on damage system, im actually trying to use multisphere trace to hit multiple targets on a melee character, but the problem is that those targets receive multiple damage in just one atk, maybe someone can help me to fix it? I tried to use "do once" but it also did not work well because then only 1 target received damage at all

[clear sierra]

Your multi can find targets, then call the ability execute which should only work once, so dont add doOnce here, add Do Once where each target recieves damage or how the ability is being executed,

DoOnce is little tricky, maybe add a cool down or something

[dreamy mountain]

is that a node or is that in the ui?

[clear sierra]

Node search Format Text

[versed sun]

Anything wrapped in {brackets} will be a wildcard variable , letting you plug things in

[clear sierra]

yes this one, One thing to take care of, Format Text is costly so dont call this on tick

[weak laurel]

Interesting, what situation you must have to call it on tick

[dreamy mountain]

ahh ok

[crystal crown]

debugging vehicle physics?

[clear sierra]

Lots of cases you can do it like this :

• If you have created a binding on TextBox and used this, that is a tick.
• If you want to format Text with data.

[weak laurel]

Don't think that you need text for debugging

[crystal crown]

how do i know what parameter is what then?

[weak laurel]

When I learned that bind works on a tick, I never used it

[clear sierra]

well for debugging, it does not matter what you use, because its not going to be present in final product

[clear sierra]

me too

[weak laurel]

yes, you right

[clear sierra]

UI should be event based, and if you can use Validation Panels correctly, you can squeez lots of FPS.

[weak laurel]

Yeap

[weak laurel]

better develop UI on Slates, Slates have their own thread)

[clear sierra]

yes much better.

[weak laurel]

how much you have experience?

[clear sierra]

experience with slates ?
I have never created UI from scratch, But i can move around the code.
I should try to create some UI using slates

[weak laurel]

no, UE

[clear sierra]

Interesting solution

[clear sierra]

6+

I am going to ask ChatGPT about this

[weak laurel]

Good)

[clear sierra]

Slate Run on GameThread, is this correct News ?

[gentle urchin]

It wasnt nice, but it worked -ish

[clear sierra]

My ChatGPT is very nice to me

[dreamy mountain]

im trying to make text appear when in range of a certain object; what would i put in object if its a blueprint ive made?

its just an actor blueprint

doesnt move

[clear sierra]

@toxic jay sometimes my chatGPT, emails the whole code, i just copy paste it.

[sage basalt]

Slate and UI in general is working inside the game thread. Performance wise you can use slate purely or inhire from a UUserWidget class and make an umg widget from it.

Doesn’t really matter these days

[clear sierra]

i believe my ChatGpt more than any documentation in this world.

[clear sierra]

you would put the object reference which should be in range.

[dreamy mountain]

idk what the object reference is tho

[weak laurel]

Something even ChatGPT don't know

[clear sierra]

No one can make me believe, sorry @weak laurel , but i am deeply in love with my chatGPT, whatever she says is the final word.

[weak laurel]

is it mutual love?)

[clear sierra]

🥹 i hope so, she is nice to me

Let me ask her

[weak laurel]

If you have hope, then all is not lost)

[clear sierra]

This is what she said

😢

[versed sun]

friend zoned

[clear sierra]

True love is always one sided. 🥹

[weak laurel]

Don't give up, you can do it!)

[clear sierra]

yes 🙌

This right? Well, I thought it would work but still nothing 😦

[versed sun]

you kids and your AI... Just go to the library and open an encyclopedia , not that hard

[sage basalt]

@weak laurel @clear sierra I guess this should answer your thread discussion

[weak laurel]

it's nothing)

[clear sierra]

There is no slate thread, My CHATGPT was right 🥳

[weak laurel]

And this is a joke?)

[sage basalt]

the slateloadingthread is only used for loading situations like loading screen or anything

but the main ui is in the ENamedThreads::GameThread

[lunar sleet]

Please use #slate for this stuff

[wild crater]

Ayy cool!

[clear sierra]

I think his solution was to add Actors which has recieved damage to Actors to ignore Array, so dont clear it here, and dont make it local variable

[coarse grove]

Yeah I thought the same but the problem is the for each loop, because it keeps "adding dmg", i tried to create a macro to delay the for each loop and it looks like a "tick dmg". I thought to create a bool inside the dmg system "isreceivingdmg" so i made it only calculates if its false, after that i change it to true so it seems to limit the damage, im now trying to find where to turn it back to false again

[versed sun]

Here is the basic setup
Loop thru each of your hits
If that actor is NOT in the array, then apply the damage and add it to array
If it IS in the array , the it already took damage, so don't do anything
the Local Hit Actor Array will reset , no need to clear
~RyckGPT

[weak laurel]

I think it will not work, maybe node take a copy of array, not reference

[weak laurel]

yes, simple fix

[weak laurel]

new GPT version, nice)

[versed sun]

Now with visual aids

[lunar sleet]

Hallucinates less, I hear

[versed sun]

well...

[dreamy mountain]

im really confused lol, it doesnt really work, it shows both in and out of collision

[versed sun]

Schrödinger's code
both True and False until you debug it

[dreamy mountain]

how do i od that

[plush knoll]

Hi, I created a blueprint consisting of another blueprint that was added as a child component. In the BP editor I am able to configure the child options. I now want to add multiple of these BP and change this child of the instance, but UE does not show me the configuration option.

Any help is appreciated 🙂

[lunar sleet]

Is that a child actor component?

[plush knoll]

Yes, I just created a new BP and added the Pole as Mesh and the Traffic Light as a BP/

[lunar sleet]

Yeah, don’t do that

CACs are broken and there are easier ways to do this

[plush knoll]

Yes, I figured that this is not right. How would be the best option?

[lunar sleet]

If you want to add multiple meshes to an actor just add more static mesh components

See above

[plush knoll]

The problem is that the traffic light bp contains some logic and functions etc. I want this as one component and I want then to create one new actor with the pole

[clear sierra]

You can also override UStaticMeshComponent, instead of creating an actor for Traffic light.

[clear sierra]

you can move all the code to Component from actor

Can you please explain what configuring you want to do on traffic lights ?

[plush knoll]

I have this BP where I can configure that light colors and the logic creates the light cyrcle etc.

Based on this, I now want to create different poles as SM that hold this BP. My problem if I copy this logic over is that should something change, then I would have to edit all BPs.

[lunar sleet]

I mean that and also does the pole need to have diff code than the traffic light itself? Why so much complexity

[lunar sleet]

No, you would use OOP and inheritance to only change it once

[plush knoll]

In an intersection I need to set the one light to start with green and the other to start with red.
