blueprint

[full badge]

also it's a bit broken if you don't preview in fullscreen but i believe it only happens in editor

[visual crest]

Ok how do I use it?

[full badge]

open the bpw_colorpicker and do something like that

up to you

and you can add it into other widgets

ok i added an event dispatcher

you should be able to add an event

[visual crest]

For the Material what goes into the texture sample?

[full badge]

huh

[visual crest]

It got lost when I put it into my project

[visual crest]

thanks

[surreal peak]

The reference probably broke due to how they work internally.

[full badge]

true

[visual crest]

is this right?

[visual crest]

they lost there settings so I am trying to put them in the right spot

[full badge]

yea

wait no

the texture render target should be WidgetCaptured

in the draw material to rt

[visual crest]

THANK YOU!!!!

This will work!!!

[visual crest]

The math you use to get you x and y is not correct its off a bit but I have no clue how to fix it.

[full badge]

huh

it works pretty fine for me

are you testing it in fullscreen

[uneven crest]

I made an actor that contains a widget. Set the blending mode to transparent so that the transparency background of the buttons can be seen. This then causes the white to glow, and also messes up the texture of the weapon. Any fix?

[visual crest]

yea I tried stand alone

[full badge]

is it offseted?

[visual crest]

?

[full badge]

oh i see it

[visual crest]

what do you mean by offsetted?

[full badge]

nvm

i get it now

fixed it

@visual crest

[visual crest]

Ok Ill check it thanks 🙂

[full badge]

is it fixed?

[visual crest]

Can you show me a screen shot of what you changed? I don't think my thing is loading it right

[full badge]

i replace the get mouse position to get platform mouse postition

[visual crest]

Ok I had to restart my project.

I see! let me test have to set paths again

[full badge]

if you just unzip it into content i think the reference won't break

[visual crest]

ah

[visual crest]

yea it works perfectly if its at 256 but If I change it at all it breakes even if I change the values in the lerps

Oh I see I have to change the render target size too lol Thanks!

[elfin lagoon]

after a some hesitation (i think, its may require a massive rework for current heroes/minions system, luckily it's not), i switch characters to two different object types, team1/team2, and this way is work as intended
thank you 👍🏻

[compact remnant]

Is there a simple way to get a data layer to not persist transform changes on unload/reload? I'd like to have it reset that each time the data layer is reloaded.

Apparently I just needed to manually collect garbage on unload. Interesting finding, I'm sure I'll forget in in 2 weeks like every other UE quirk.

[astral summit]

I can't put a new line in a text variable in a data table.
Any solutions?

[spark steppe]

in the struct definition enable multiline for that field

[astral summit]

I didn't find it

[spark steppe]

the last one

[astral summit]

It works thank you

[eternal sandal]

How can i make an inventory (array of three slots) thats different for each character and to work in multiplayer? (like when each person picks up a new weapon it gets added to their inventory seperately)

[frosty heron]

if you never make an inventory for single player, doing it for multiplayer is certainly a frog leap.

[eternal sandal]

i copied this from a guide and it works

so i guess i have one for singleplayer

[astral summit]

Is there a way to make variable an Array that has two indexes instead of one?

[frosty heron]

Multidimensional array is not supported in blueprint

[astral summit]

The branch does the trick

[round grove]

Is there a way to set the performance of spawned lights?

[still sigil]

Hey, I'm having an issue with attaching a physics actor to a component. I'm trying to create a sorta Zelda style pick up and throw system. If I uncheck Simulate Physics right out of the gate, it works perfectly fine. The object attaches to the socket and everything. But the second I turn it on, it will completely refuse to attach to the socket in any way. Even turning off Simulate Physics right before the pick up action as shown here doesn't fix it. If it's checked on at any point, the actor will not attach at all. Any suggestions?

[merry topaz]

Hi! I'm using UE 5.6.0 and added the Paragon: Wukong asset from Epic. I'm getting some warnings in the character Blueprint. Attaching a screenshot — any idea how to fix? Thanks!

[sage jungle]

Hi do you try to attach and set off simulate physics in this order?

[still sigil]

Turned Simulate Physics off first, then attach, yes.

[terse bluff]

I think you may want to try to have Weld Simulated Bodies checked

[still sigil]

Tried that too and it still didn't do it.

Actually it was on by defailt initially, so I unchecked it to see if maybe that's what was causing it, but it was not.

[terse bluff]

Is the Cube a child component of Self (eg. same actor that you pass to the Target of Attach Actor To Component)?

[still sigil]

It is, yeah.

[terse bluff]

Is it possible that the root of the actor you are trying to attach is just a default root and not some sort of a static mesh of which cube is a child (so cube simulated together with the root of it's actor)?

[still sigil]

That is correct.

[blissful summit]

How can I make it so that pressed sets to true, and released sets to false?

it just spams true

[terse bluff]

That's the issue, you perhaps want to make a cube to be a root of the actor if it's "main" pickap-able mesh. Otherwise you attach the actor, but cube is sort of separate component still

[still sigil]

Hmm. I think I had some sort of issue with my box model when I tried to do that, (Can't quite remember what, it's been awhile.) so I opted to just keep it separate from the root in the end. I did manage to find a work around to my issue by just spawning a separate actor with the physics already disabled the moment it's loaded in. (With it being reenabled once it's thrown.) but I'll keep this in mind in case I run into another issue like this in the future. Thanks for the help. 🙂

[nova grotto]

hi guys i wanna make a fighting game jump in bp where you dont have any control after you jump but the jump goes on a consistant arc every time how would i do that?

[sage jungle]

why do you use Triggers?

you need triggers for specific thing?

[lofty rapids]

press the arrow down, theres more execution lines

[trim matrix]

UE is going to make me crash out... vehicle blueprints with chaos vehicle setup and the wheels losing collision/physics when running game. Now, I think I have attempted all ofthe fixes I came across on google and no change. However, I found when I remove wheel class (set to none) that the physics and collisions now work but the wheels just kind of collapse the vehicle, they just slump over. There's no settins in wheel class to affect physics/collision. What is going on?

[blissful summit]

those are triggering completion for all triggers being completed

[lofty rapids]

theres started and completed usually

[blissful summit]

what is the correct way to do it without triggers?

[blissful summit]

those do not give a true boolean for some reason

[lofty rapids]

you set the boolean on started

and set it on completed

should be fine

[blissful summit]

yes thats what i thought too

but it always false

[lofty rapids]

show the code, your doing something wrong

[blissful summit]

thats literally all there is to it

besides adding the input binding to the controller

its all bp

[sage jungle]

how? if you hard set "true" on Started and "false" on Completed you can't have always false

[blissful summit]

maybe I am going insane, I will try it again

[lofty rapids]

and show the code after if it doesn't work

[blissful summit]

there is no code

just BP

[lofty rapids]

ya show the bp

[blissful summit]

the screen shot i sent

is all there is

that input is not being triggered anywhere else

[lofty rapids]

did you read what i wrote ?

because that screenshot is not it

[lusty solar]

Hello there ! I've a problem with my dispatchers, they don't seems to work. I've two issues, first I've a OnPlayerLanded dispatcher in my fall state that doesn't want to be deactivated, and secondly, in my jumps states, I use the OnReachedJumpApex to go to the fall state, but for some reason, it doesn't subscribe...

[lofty rapids]

can you show your binding, and calling ?

[lusty solar]

in my jump state :

In my fall state :

for my others jump state, i use exactly the same binding

the calls are made by the player movement AC

I'm following a course so i've my version and the course verions of the states and strangely, in the course verion, the bindings works while being exactly the same code as in mine

[merry topaz]

I figured it out! The issue was caused by the new Enhanced Input system in Unreal Engine 5. With this system, I needed to create new Input Actions (like Move, Jump, etc.), then group them into an Input Action Map.
After that, I had to assign this Input Mapping Context to my character via Blueprint. Once I set that up, everything started working correctly — inputs are now responding as expected, and the warnings are gone. Hope this helps anyone running into the same issue!

[midnight field]

I've started segmenting my experimental project into plugin folders, copying a few little utilities from Lyra here and there.

I've run into an issue where a particular data asset is unable to reference another data asset that's in the same folder, but is still able to reference those in the base project folders. Is there something I might be missing?

[uneven crest]

I have a 3d actor with a widget that is sent to transparent bledning mode so that the transparency background shows up, but it then causes the textures to mess up. How do I fix this?

[tight pollen]

I have a problem, I have 2 actors, the first one creates the second one and sets references for it, in version 5.3 everything worked, and now in version 5.6 it does not set the variable

some ideas?

[uneven crest]

Wdym it doesnt set the variable

[tight pollen]

I don't know

I just changed the version to 5.6

I use Add Child Actor Component and just set variable (Reference to Parent)

in 5.3 is ok

but 5.6 :/

[steel shadow]

You set the variable inside the child actor yeah?

[tight pollen]

yep

[steel shadow]

Show your bps

[void glade]

does spawning an actor inside a function delete the actor when the function completes?

[hardy merlin]

No. Actors persist until you explicitly destroy them.

[void glade]

That's what I thought. Welp.

[hardy merlin]

What are you trying to do?

[void glade]

Trying to figure out why a specific function isn't spawning it's actor. I think at this point though my best bet is to take a break and come back to it later.

[tight pollen]

and when Begin Play in BP_Test then Ref is not valid

[steel shadow]

Any reason it has to be in construct

Show your validity test

Try putting it in begin play (the add child)

[tight pollen]

doesn't work either

doesn't set the variable for some reason

[steel shadow]

Show validity test

[tight pollen]

also Is Not Valid

it is weird

[steel shadow]

I haven't seen that type of get node before.

Are you in single player

[tight pollen]

yes

[steel shadow]

Try a normal get node?

And a normal is valid check

[tight pollen]

ok if I set it at start play it works

but why Construction Script stopped working, it should set variables etc.

[steel shadow]

Idk some weirdness with tick/initialisation order

[hardy merlin]

Check spawn settings. Is it Always Spawn?

[tight pollen]

anyone know the solution to this? I don't want to use Begin Play

previously Construction Script set variables, and now I don't know what happened

I do exactly as here and it doesn't work ---- UE5.6

[hardy merlin]

It's generally a bad idea to spawn other actors inside a construction script, because the construction script will get run over and over during editor time.

Can you do what you want in Begin Play?

[tight pollen]

but I don't spawn actors, I just add components to the current actor

[steel shadow]

It's both an actor and component

[shell tide]

Is there a way to automate a line break when commenting a node? It’s pretty annoying to press Shift+Enter every time. The ideal thing would be for the comment width to match the width of the node, and then, when typing, it would automatically break the line as soon as you hit the edge of the node. I haven’t found anything about this in the settings.

[narrow sentinel]

Anyone ever had this ?

you can see there the variable is set and valud

*valid

but down on tick it seems the variable is not set and is null, I'm bit confused how this can be both valid and not valid. I don't have anything else messing with that variable so

is there anything I can use to see whats going on ?

[frosty heron]

Its called validated get. You right click an object reference and the option should come out.

[lunar sleet]

In certain instances you can’t see the actual object properly when you hover because you’re not far enough into the execution. Try setting a breakpoint on the next node and then hover

[narrow sentinel]

so I instead used the is valid node from the ref so this

and oddly is seems to be behaving now so not sure what the difference would be between using the is valid node and the validated get thingy

unless it's what you've said above but yeah odd

[leaden tree]

hello! I'm getting construction script conflict while doing audio analysis. I'm following this doc: https://dev.epicgames.com/documentation/en-us/unreal-engine/audio-synesthesia-in-unreal-engine?application_version=5.5

if i dont use construction script, the audio plays, but no analysis can be done

[steel shadow]

Oh cool

[charred granite]

Hey everyone, I'm currently trying something simple, I want to add a wind sound effect when my character is sprinting, and I want it to stop when he stops sprinting (I'm aware there might be better ways but I'm just trying something basic, simple real quick).

I thought by adding it to my sprint logic, that it would work. It kinda does, but also when I STAND STILL and press shift (keybind to sprint), it will also play when I'm not moving. Any tips on how I could solve this issue, would I need to use nodes for velocity or location or something? Here's my current Blueprint node :

[steel shadow]

Why do you have a delay of 2 if you already have a fade in time

Also yeah you could have wind sound tied to velocity maybe recalculate it every 0.1 secs

And have a non linear curve so it's much more noticeable at higher speeds

[charred granite]

I shouldve deleted that first before taking a screen, my bad. I left it for now as Im trying to figure out the main issue that Im having

[steel shadow]

Also if you sprint for less than 4 seconds that will give janky behaviour

[charred granite]

Ill give that a try

[olive yarrow]

we've established casting ain't bad. on that note though, are we suuuuuuurrrreeee adding too many things to Event BeginPlay is bad?

[steel shadow]

Adding too much to anything can be bad

How much is too much?

[dark drum]

I can't say I've ever heard anyone saying too many things OnBeginPlay is bad. 🤔

As with everything it's about what you're doing and how frequently. A 1k loop (whilst heavy) on begin play could be fine if it's only one actor. Having 100 of them doing the same thing on the other hand.

If you're not sure about a particular setup, profile and find out the performance cost.

[olive yarrow]

not heroin /s

[olive yarrow]

It's mainly just a couple of "Get actors" and junk, fires once no loop

[dark drum]

It might be easier to show what you've got. 😅 From that description it could be anything.

[olive yarrow]

this is true... hold that thought

[dark drum]

I can't see anything that's troublesome. Granted I'd probably handle things differently.

[olive yarrow]

oh yeah i defiinitely still lay my stuff out like a novice. But lemme tell ya it's way better than once was, though i could likely have all those Gets in a custom event of its own... eh what can ya do

[faint pasture]

Doing so much work in one frame that your framerate suffers is bad. Doing that work inefficiently amplifies the bad.

But if the work has to get done, it has to get done. If it's bad enough to make the game a stuttery mess, then either make it be done more efficiently (C++), or spread over time.

[olive yarrow]

heard, gimme that knowledge

[dark drum]

If you're looking for things to learn to improve your systems, look into hierarchy, composition and uobjects.

[gilded flint]

Hi, how can I detach a actor from my Third person character? I tried detach but when it detached I can't see actor(mop). I think problem is setting world location but how can i set it?

[steel shadow]

I feel like unless you're doing something heinously wrong it's mostly GPU time you end up needing to optimise

[gilded flint]

me?

[olive yarrow]

whoa momma

[dark drum]

May I introduce you to the sequence node? 😅

[steel shadow]

The average dev, including me

I got massive performance increase by making texture atlases and reducing draw calls on my meshes, unfortunately I need to do it some more I think but some of my original skeletal mesh sources got corrupted

[granite nacelle]

I have a small issue where the mesh will lean left and right when I click on force root motion and enable root motion what could be causing this

[faint pasture]

is the pelvis the root bone?

[granite nacelle]

yes

actually it says root then pelvis

[faint pasture]

show it

show the skeleton heirarchy

[granite nacelle]

got the animations from mixamo, it wasn't always like this it just started happening out of nowhere

[faint pasture]

can you confirm that the root bone in this animation just translates, without changing orientation?

root lock should just mute the root bone anims so if the pelvis is doing stuff to counteract the root rotating then the problem is with the anims

[granite nacelle]

Dont know what you mean, how can i confirm it?

also the animation was not modified in any way was just imported into unreal

[faint pasture]

look if the animation has the root doing anything but sliding forward

[granite nacelle]

Doesn't look like it to me

[faint pasture]

yeah your anim is borked

[granite nacelle]

It just started happening one day and I dont see anyone else with this problem

[faint pasture]

Might be a Mixamo export problem I thinik

[frosty heron]

This is not true at all

You optimize where you need to optimize.

Expensive algorithm that run on cpu side such as dungeon generator, or anything with expensive operation should be optimised.

You can easily stress out your CPU with shit algorithm.

[steel shadow]

Yeah hence the 'mostly'
And bad dungeon generator would class as 'heinously wrong'

[frosty heron]

There's no such thing as mostly

If it's too heavy and can be optimised then do that.

There's soo many things you can do to optimize cpu side.

Have good data structure and when possible offload to GPU

[steel shadow]

Yeah but it's pointless if you are GPU bound right

[frosty heron]

Apple and orange

[steel shadow]

Because CPU waits for GPU so if CPU is faster it's irrelevant to optimise it

[faint pasture]

It's pretty hard to make something that occassionally results in a 500ms frame GPU side but that's really easy to do with some bigass function CPU side

in Unreal you have way less control over making the GPU do some big dumb thing than you do on CPU. I can make a function that'll take 10 seconds to run on CPU

[steel shadow]

Well yeah but assuming sensible, but not perfect code

Like not get all actors of class on tick or something and the actors are all enormously complex

I am right in the CPU GPU thing right? My understanding is both processes start in parallel and when the GPU finishes it sends commands to the CPU, which has to wait to receive those commands and execute them before the next frame is 'called'

I don't mind beong wrong in fact I'd prefer to be. At lot of my profiler stuff is 'CPU Stall' which I'm assuming is waiting for gpu

[runic terrace]

You can see in the profiler what the frame is doing

If the majority of the milliseconds are used up by the lighting, rendering stuff etc it's probably the gpu

otherwise it's cpu

[steel shadow]

Game thread is mostly CPU stall wait for event

Render thread is a bit that but is mostly render view family

[frosty heron]

If your game take a hit, profile it and sort out the ones taking the frame, be it CPU or GPU.

That's it.

No such thing as mostly this or that

It really depends on what eating your project.

Because you can eat all your budget in both cpu and gpu

[steel shadow]

Yeah I did and I see CPU stall wait for event

So I'm assuming CPU is waiting for gpu

[runic terrace]

both is kind of waiting for each other

it takes both of them to generate a frame

[steel shadow]

Well I think GPU waits on CPU a bit to actually execute its own (the gpus) commands

But I think that is a lot faster

Than the wait of the cpu

[cyan wren]

Super new to unreal, like this is one of my first blueprints new

Im wanting to color shift a health bar depending on the amount of health a player has, i dont know how to return the numbers to the thing though

[full badge]

try just do "make linear color"

[cyan wren]

Words cannot describe how cool you are lol, thank you so much!

[little helm]

I'm working on localization. I've setup the localization in my game but font is not supported in some languages. Is there any way to change the font in all the widget at once ?

[surreal peak]

CommonUI has TextStyles you can create as Assets and assign to CommonTextBlock and similar. But changing the style is still not something you can do all at once for all widgets without coding a custom system for that.

But if you would want to change that specific style instead of swapping it out then the style is definitely the superior solution than hard coding that stuff on each TextBlock

[merry mirage]

Another solution if you want to avoid CommonUI is to make some sort of central UI-manager which can keep track of what font you want to use and then create a Custom Widget containing a textbox which listen to a "OnLocalizationChanged" event dispatcher from the manager

[dark drum]

Its an interesting problem I've often pondered from an accessibility setting perspective, mainly for text size. One of the big issues is that changing the size and font of text could alter the UI layout. (Just something to be aware off)

I would go down a similar route epic did with common UI and create a data asset for defining fonts for text. You could then have it specify a font for each language. The data asset can then have a 'GetDesiredFont' function that returns the font based on the current language.

You'd most likely need to create your own custom text widget that binds to some central manager that detects when the language has changed. Of which would just make it fetch the desired font from its assigned data asset again.

[inland walrus]

I use this method (dt) of getting my dialogue (map) but I can only get 2 variables whilst using a map, is there a way I can get more per dialogue? i.e. audio wave too

[lofty rapids]

probably a structure

map, string key, to structure value

right now you have string key, string value ?

[frosty heron]

A map is a key value pair

You most likely didnt pick the correct data structure.

[lofty rapids]

i know blueprint structures can be a menace, but i definately think in this case it's what they need

"there are known issues with structures in Unreal Engine Blueprints, with users reporting them as unstable and prone to corruption"

it's better to make your struct in c++ if you can

it's either a map of string to structs, or a bunch of seperate maps which is a nightmare

[inland walrus]

yeah

[frosty heron]

You can think of map as a dictionary

[inland walrus]

Everything currently works but I wish maps could add more than one extra variable as I am going to have to have multiple maps for 1 dialogue

[lofty rapids]

struct ftw

[frosty heron]

I think that's just not understanding what map is as data structure.

Read or watch some materials before usage imo.

[lofty rapids]

have you ever used a struct ?

[inland walrus]

yeah

Everything I have works, and I can make it work using other variables, I just wondered if it was possible to do it all in the same map etc

[lofty rapids]

well you can read above to see what to do, you can definately do that

it's string key, to struct value

but like mentioned you may need some tutorials on what exactly a map is

and how it works, so you can do this

[inland walrus]

Alright and when you say read above, are you referring to the c++

[lofty rapids]

just what i wrote above, instead of me repeating it you can scroll

[lofty rapids]

definately this as well, if you can make the struct in c++

[frosty heron]

Remove the if

Just do it unless you want to shoot your self in the foot

[inland walrus]

I'm already using a structure?

[lofty rapids]

if your referring to map as a data structure then yes, but there is a specific thing called a struct as well

[lofty rapids]

https://www.youtube.com/watch?v=koz7J1fBNis

just backup your project

and make backups often incase the struct breaks

because in blueprints structs have been giving people problems, ig they are not very stable

i have not had problem yet, but i have not edited a struct that i use a lot

[lofty rapids]

once you make the struct, set the map value to the struct, and bingo you got the multiple properties in a map

[frosty heron]

But what would be the key be?

If you need to know the index and you dont need to find a value by the key then a map is not for you.

[lofty rapids]

the key is a string

thats what they have a map with a string key, and they want more values

atleast thats what i gather

[kind estuary]

oops wrong channel

[frosty heron]

But what does it represent in the context of dialogue system?

[kind estuary]

actually, how do i save a reference to another actor, in the save game? Is there something im missing?
When i load it the reference is now None <-
Id swear i figured this out in the past.

[frosty heron]

Because they are destroyed when you exit the app.

[lofty rapids]

idk, they said they were using a map and needed more items, thats the solution, i didn't go into why they needed a map in the first place

[frosty heron]

Object reference that is created not at run time will exist though, e.g the one you place in editor

[kind estuary]

hmm, so what should i do here

lets say you have a Unit, and then you have CurrentBuildingReference (Actor reference) reference

[frosty heron]

Ask #cpp

[kind estuary]

When you load this one will be None

[frosty heron]

For my old game, i just the state of the character. When loadong new game, create a new actor and load the saved state.

Haven't got into a more advance save technique

[kind estuary]

yeah but then your character might have in it references to other actors such as, the CurrentTile (Actor), the CurrentPlayerOwner, the CurrentSpawnedWeapon...

these references all become None when loading

[frosty heron]

Told you already run time object are destroyed when you exit the game or level.

So when you load it back up the object reference cannot be resolved

As its point to something that no longer exist.

Ask in #cpp if theres a way to seriliaze it

[kind estuary]

🌽 🥛 🥣 I hate cerealizing

ok will ask #cpp

[frosty heron]

Don't ask chat gpt

[kind estuary]

thanks

Hey guys, Is there anyone who have worked with Convai plugin before? i am struggling with something and i need help.

[lofty rapids]

they don't have a discord ?

[narrow sentinel]

Anyone know how to stop camera placed in the world from being selected ??

[lament spear]

i couldn't find one.
the problem i'm facing is rather specific and it's not there in their forum or documentation

[narrow sentinel]

it seems when I click and drag in say the top view near a camera thats placed in world it's selecting the camera aswell even though it shouldn't be

[thin panther]

why not make a post on said forum then?

[lament spear]

it's not that active. I need a solution urgent

[lusty solar]

Is there a way to keep a CreateEvent ref into a variable in BP ?

[frosty heron]

Function pointer?

[sage jungle]

only in c++

[frosty heron]

Ye but I'm trying to figure out what he mean

I mean delegate can be a variable? Not sure

[sage jungle]

You can't but do you try Event Dispatcher or Blueprint function library?

[frosty heron]

I mean its not really useful in bp anyway

Imo

But I'm no programmer so take it with grain of salt.

Not like you can pass function as a param in bp

[sage jungle]

mmh okay

[lusty solar]

I have a bug where one of m dispatchers wont unbind, and it's already been like three days that i tried to debug it so i asked GPT if it has an idea and it told me to get the ref. That surprised me because i did'nt saw it was possible

[frosty heron]

Stop asking chat gpt for this

Debug where you unbind and whwre you bind.

It may be you bind after unbinding

[lusty solar]

yeah i'm kinda desperate

[sage jungle]

mmh you can but with caution
GPT is ok sometimes

[lusty solar]

I did, and their both called

[frosty heron]

I see it done more harm than good

[frosty heron]

Then look at the order they are called.

There's no reason that unbind does not unbind

[frosty heron]

I never said to never ask LLM, but asking about blueprint problem will just make one want to punch the monitor.

[lusty solar]

bind first, then unbind, there is no problem in the order

[frosty heron]

This screen shoot doesnt say much though.

[lusty solar]

but when i land in another state, it also call the land in my fall state

[frosty heron]

Well im c# an event is just a collection of pointers iirc.

I wonder if you can actually see what function bind to a delegate if you debug the project with an IDE.

[sage jungle]

you bind/unbind dynamically a dispatch event?

[frosty heron]

Its impossible to know with this screen shoot alone.

[lusty solar]

yeah i also do C# that make me think that it might be a compilor error or something like that

[frosty heron]

No

Your project wont even build if you have any error

[lusty solar]

it's probably not that i know, it's my frustration who talked

[frosty heron]

Im gonna head to bed but maybe show others how you bind and unbind.

[lusty solar]

those are my bind/unbind

[lusty solar]

ok good night

another strange thing is that i use the exact same calls in other states and it work just fine!

[lofty rapids]

when you unbind, why it says -> Hit also ?

looks like two different signatures ?

i mean basically the same

but you got extra -> stuff on the unbind

[lusty solar]

because it has a hit parameter i guess ?

will look that

[lofty rapids]

well they both do

[lofty rapids]

drop it down and see if you can make it match the other one

[lusty solar]

those are old catpture, they both have the -> hit now, and the issue still there

[lofty rapids]

i feel like your just creating new events so your not unbinding the original ?

[lusty solar]

that what gpt said, but that what i've always done and it always worked

and still work in my others states

okay, i tried creating a new function bind to the dispatcher, and it seems to work, for now

https://tenor.com/view/incident-gif-2747499635347300991

okay it works

[sage jungle]

i have a question, you old linked function had a return value?

[lusty solar]

no, that why i asked, i was surprised that gpt told me to do that

[lofty rapids]

it's not possible in blueprints lol

theres no event type for variables

[sage jungle]

delegate do not support return value, only void functions (but it's supported on c++)

[lusty solar]

i still don't know why it fixed it but as long as it works, that what matter

[lofty rapids]

i'm not surprised, ai always comes up with stuff that doesn't exist

[sage jungle]

ChatGPT and other AIs will often ensure you have a solution

[lusty solar]

after 5 hours of searching, it was my best option

[sage jungle]

you need to use think option with gpt and Unreal
(and still doubt his answer)

[lofty rapids]

i use it for all kinds of stuff, but its wrong so often that it kind of not as usefull as it could be

[lusty solar]

i think it's usefull to guide your search towards things you havent thought of

that was what i asked, i telled it what i've done and the result that it gives and i asked where should i searched next

but it tried to solve the problem itself anyway...

[dark drum]

GPT is a good sound board and can help prevent spending several hours navigating googles poor search results as you try to find relevant search terms for something you know little/nothing about.

[heady plover]

Greetings to all. I'd like your help regarding a list of all static mesh inside a Map using all actor class and print functions to get the text from the output log and then transfer it to excel for organising the assets.

My Map contains approximately 300 unique assets which were combined into packed level actor BPP Mass to design the level but the total actor count became 40k plus and I need to make a list of total model names inside a particular area or loaded world partition in this Map.

I was able to get a list of the total 300 model names inside the Map using get.all.actors function , a for loop and print functions to get text in the output log.

tldr: I can get a list of all models inside the Map but I require the list of those which are inside the viewport or certain area or inside a cube or inside a loaded world partition.

[sick sky]

i have better results with google than gpt tbh

just avoid reddit most of the time

[dark drum]

Yea i still use google but often use GPT to give me more details on context. It often gives me better key words that can give better results. (assuming it doesn't answer the question)

[spark steppe]

also helps digging into the right part of the engine

or getting lost for a day...

I feel kinda dumb rn. I've create material instances before but I can't seem to get this to work or remember how to do this. I'm trying to make a material instance of the material selected for "Progress" which is an image widget. What am I doing wrong/forgetting?

[lofty rapids]

are you forgetting to assign the new material you created ?

yes realized that but still nothing

[lofty rapids]

make sure you paramater name is correct, no space at the end

Does the standard save/ load game function not work on loading certain variable types?
I'm trying to save and load third person character data and nothing is being update. But updating an int works fine.

[thin panther]

define third person character data

are you just trying to save a reference to the third person character

[storm solar]

Base third person character BP with demo project that is parent of Character BP. I save the contents of it in a save game BP under a third person character variable type.
It looks like it's saving it as reference.

[unique bronze]

hi devs, I kinda need a recommendation.
For a spell projectile Im using a Sphere Collision as Parent which evaluates the overlap events, but now I cant scale it with the projectile together. The spell grows, so should be its collision.
Im using User Parameter to scale my niagara particle up at runtime, this works flawlessly, but the Collision Sphere cant be increased at runtime, would you suggest not using Sphere Collision but something else instead?
Any consistent and more efficient way to scale collision and particle equally at runtime?

I got so far with your help everytime I got stuck, appreciate any help again!

[frosty heron]

Is scaling the whole actor dont work?

[frosty heron]

Your load game path will always goes to cast failed.

Since you are cross pinning

[storm solar]

from save ref to cast to bp save. I thought so too but It doesn't fail for me.
(I was following the tutorial as close as i could https://youtu.be/kdJ4_pry8GA)

[unique bronze]

You mean like this? It worked, thanks a lot! I had to divide the number by 100, for some reason particles are in range of 1-100 ok, buit 1-100 for Actor Scale 3D its 100-10000. Dividing by 100 the same number which is given to particle feels kinda dirty tho 😅 , but it works, so its okay, Im open for any other way! Thank you!

[frosty heron]

Read what i said about cross pinning and the part where you loading.

This is a mistake

[frosty heron]

You can use mapRangeClamped for future reference.

[storm solar]

The load path is not failing.

[frosty heron]

Thats not the same picture as the one i repli3d to.

[frosty heron]

This one here

The top right pic

[unique bronze]

thx! Ill give it a go

[thin panther]

What Coldsummer says is right, however you do have another issue. Saving an actor reference only works if it's an editor placed actor. The third person character shouldn't be, and thus that won't work

Stick to saving simple types, if you want a good save system, give C++ land a visit

[frosty heron]

Also dont load in UI.

Widget should just read state.

[storm solar]

I said earlier that it dosent fail for me.
cast succeededs regardless of cross pinning.

[frosty heron]

Lol

I mean you are not even showing the same function when replying to me.

Oof no kidding the tutorial actually load and save in UI 😵

[storm solar]

so whats the issue here?
I've done this with and without cross pinning.

[frosty heron]

Yeah when you go from the top your cast will guarantee to fail.

[thin panther]

it's setting a variable and the bottom is reading the same variable

[storm solar]

So why is it not failing?

[thin panther]

crossing execution lines like that is still a no no in my book, but it is technically valid

[storm solar]

This is what I needed to know. thanks.

[frosty heron]

I dont normally cross pin because that's invalid way of connecting your blueprint nodes, but i can see why it work on this instance.

What you should do is plugging the save game variable that you have unpinned there and not the one from the set node.

[storm solar]

and by that extension BCP or actor component wont be saved either? Is there a list of data types that can and cannot be saved.

[storm solar]

I am doing that. I stated that 3 times.

[frosty heron]

Yeah you are still cross pinning which is a no no.

Just because it work in this instance doesn't mean you should cross pin.

As for object created at run time they get deleted when you open a new level or exit the application.

So when you load an object reference (blue pin) it will just return null as it point to something that no longer exist.

Actor placed on editor time however can be saved as their path can be resolved.

[storm solar]

What do you mean by actor placed on editor time?
When an actor Is put in the game world before the game is ran?

[frosty heron]

Yes

[storm solar]

thats what im doing atm.

[frosty heron]

Where does your code fail?

Before loading you can also check if the save file exist using DoesSaveFileExist.

If you never create the .sav then you may not be loading anything.

[storm solar]

it succeeds.
It's not having an issue in that regard.

[frosty heron]

state the actual issue

[storm solar]

You said I can save actor data on editor time since their path can be resolved.
I cannot do this as the values is still passed by reference.

[frosty heron]

Actor reference will be valid for editor time placed actor.

If you cant get it then you are doing something wrong and we have yet to see the part that you are trying to load (save game ref aside)

Also you have to define "actor data". Blue pin = object reference.

Gets deleted at map change or when one exit the game.

Saving a reference (blue pin) will only be valid for editor only placed actor.

If you are spawning your character through defsult game mode, that is created at run time, not editor placed.

[frosty heron]

Print string the player reference, if it's not null then you indeed have load the actor reference.

Do note ofc. Loading the reference doesn't mean it will load any previous state what so ever.

It will just find the object reference, you will still have to save and load the states (e.g abilities, hp, etc or any other data type you may have)

[storm solar]

As their premitive data types and not an actor component?

[neat haven]

I'm trying to create a system where the player click on an object, a widget will pop-up with a button with the text "walk to", making the character walk to that object. I tried chat-gpt and gemini to help me with that but now I'm stuck since I don't know how could I get a reference to the controller inside this widget. Btw, if I'm not doing this following the best practices I would really appreciate someone to point me to the right direction/resources. Right now this code gets compiled but event though the location of the chair is printed, the character still doesn't move.

[lofty rapids]

i think your getting pawn, and trying to cast to controller? this is probably failing ?

[lofty rapids]

one player or multiplayer ?

[neat haven]

Sorry, but I'm not sure what you meant

[neat haven]

one player

[lofty rapids]

get player controller

index 0

[neat haven]

so this?

Still does not work

[lofty rapids]

did you set the controller in the override ?

world settings, game mode override, what does it say for your player controller class ?

[tight pollen]

how can I get parent class from child actor?

example: BP_Book is child of BP_Item

[frosty heron]

It tries to get the pawn then from the pawn get its controller.

[tight pollen]

how can I get BP_Item class

from BP_Book

[maiden linden]

I'm looking to find the current Y rotation of an actor and convert it into a float

[lofty rapids]

get actor rotation, split the pin

right click the Y, promote to variable

[frosty heron]

If the game is not networked and single player then look at top down example blueprint. It already handle movement part.

[tight pollen]

someone?

is it possible without C++?

[lofty rapids]

there is no node for it, you can make a function in c++ and expose it to bp

[lofty rapids]

you can do a bunch of is class child of checks on a list

thats about as close you can get in bp

[sick sky]

Get Class ?

[faint pasture]

So why ARE there so many damn wrappers for things in this engine? Digging through Chaos is like opening up a Pepperidge Farm loaf

[steel shadow]

Is it a 3d widget that you are setting as child of the clicked actor?

[steel shadow]

You can do a 'class is child of' check would that help you? I'm not 100% sure here but I think that would return true for all classes in the inheritance hierarchy, so parents, grandparents etc

[unique bronze]

I cant figure out how to scale both proportionally, the value mapping works, but scaling the Actor scales Sphere and Particles unproportionally. The BP is fine by itself. Its like The partilces Uniform Size has not the same multiplier as the Scale Actor 3D node does 🤔

[tidal ridge]

hey i dont know what channel talks about unreal blueprints but for Aim and shooting EnhancedInput why not connect it to trigger than Completed and Canceled?

[lofty rapids]

because triggered will keep firing and trigger it over and over

so it would just keep flipping back and forth while you held the key down

[hardy merlin]

Is there a way to compare the values of the component of two actors and see the differences? For editing purposes.

[tidal ridge]

So if i hit the Left mouse button (Shooting Input) it will not pause or stop firing if the node if its connected to Triggered?

[lofty rapids]

if you hold it down it will keep "triggering"

and this would keep flipping the boolean back and forth

as for if you use started and completed, once you press it's true, holding doesn't do anything, and on release its false

[full badge]

wdym by compare the value of components

[tidal ridge]

but what happens if i let go of the mouse button will it pause or stop shooting, since holding down the button will only shoot?

[lofty rapids]

if you had this flip flop situation on triggered like you did, when you let go it could be shooting or maybe not, depends on how it lands

[hardy merlin]

I've got two different characters. One can successfully walk up a particular step and another cannot. I'm trying to find out what is different between them.

[full badge]

maybe it's the max step height in character movement component

[tidal ridge]

do i need a branch that will help to see if shooting is true or false or is better to just do the other way?

[lofty rapids]

better to just do it the correct way which would probably be the second way

[tidal ridge]

oh, so the branch would not help at all?

[lofty rapids]

the branch you have does nothing btw

you have if it's true set it to true

if it's false set it to false

so it's not flipping back and forth actually

it's just doing nothing

but the second way is what you want, trying to do this with triggered sounds like a pain

[hardy merlin]

They are identical.

[tight pollen]

Do you know any tips for optimizing lights that cast shadows and are movable?

[frosty heron]

The scale may be defined by the Niagara particle

[surreal peak]

You can use Triggered just fine tbh. You just need to use a Pressed and a Released Trigger and then you can set your IsShooting to the ActionValue.

That value will be true on pressed and false on released.

With those triggers it will also only call once per, not constantly.

Also #enhanced-input-system would be the right channel for this

[cyan wren]

New to unreal, trying to make it so object hit by hitscan have impulse applied, wondering what im missing

(first part of video is how it should be, second is stand alone)
https://youtu.be/lwHKSitv1bY

Cards are just static meshes that I'm adding force to if that matters

[tribal dock]

Hi! I'm trying to create a "ground pound" attack. I've created a mesh and I'm scaling it for the collision of the attack, but if the player is still the overlap doesn't register! What could I be doing wrong?

[unique bronze]

Sorry I cant follow 😅
If I scale actor without scaling niagara, niagara wont scale up, but the collision sphere with actor does, which is good.
For that I scale niagara with a User Paramer applied on uniform scale.
They both scale independently since scaling the actor wont scale its niagara particles, so I have to scale them both at the same time in BP.
But for some reason the scales differ, like one is linear, the other exponential, and I cant figure it out to even do the simple math, since the numbers show the same, its like Im missing some vital info about their scaling algorithms.
Its like they are internally having some kind of different calculations, but its not *100 😐 otherwise I would have just /100 and gave it to the actor if it were that easy

[little helm]

I'm switching the language in my game from english to japanese and then back to english.
When I play game in unreal editor in standalone Mode then it works fine.
But when I do the same in shipping build then the words which translated in japanese got hidden in build.
How to solve this issue ?

[full badge]

might be some fps affected problem since in editor the max fps is limited to 60

[sour warren]

Does anyone know how to cycle through active splines in blueprints? I have 4 splines in the same blueprint, and I want a particle system follow each different path every time I push a button. Now I only managed to have the particles follow the first-created spline. I tried to use activate/deactivate nodes in the event graph but still can't cycle through splines.

[maiden wadi]

Does it work in Standalone? If so, the packaging might not have picked up the Japanese loc files.

[lofty rapids]

so basically what you can do is change the spline reference

[lofty rapids]

what bp is this in ?

[lofty rapids]

try multiply the force by delta time ?

[sour warren]

I created a monochord instrument with a movable fret, and a particle system animation, so when the fret is at 1/2 of the monochord length the animation is a 2-phases sine wave, when the fret is at 1/3 of the length the animation is a 3-phases sine wave, when at 1/4 of the length the animation is a 4-phase sine wave, etc. So I have this blueprint with the monochord (a cable) that when plucked should fire th particle sys animation, and there is also the fret referenced to the button, so when I push the button the fret moves and the selected spline should be the right one. I created the splines directly into the BP viewport and I would like to activate and deactivate them with the push of the button, like this:

• push 1, fret position 1, spline 1 for animation
• push 2, fret position 2, spline 2 for animation
• push 3, fret position 3, spline 3 for animation
• push 4, fret position 4, spline 4 for animation

[lofty rapids]

^

i think this should work

[sour warren]

the particle system is a niagara custom one with the reference to the BP_monochord into the scratch module

[sour warren]

how do I do that?

[lofty rapids]

well how do you put it on the spline ? with activate function ?

[sour warren]

this is what I'm not understanding, because it fires by itself without any hard-wired reference to that particular spline

the reference from the particle system is in the scratch module, but it references the whole BP

and it seems it uses the first-created spline, so if I delete the first spline it uses the second, etc

[lofty rapids]

whats spline 1/2 and spline 1/3

?

[sour warren]

they represent the string vibration as a standing wave when the fret is at 1/2 and 1/3 of the monochord length

you see that is the string with the fret, and above there are the 4 sinewaves at different frequencies as 4 different spline paths

each colour is a different spline, so a different path for the particle sys

[lofty rapids]

do you spawn this emitter, or place in level ?

[sour warren]

is placed in the level

this is the blueprint, I tried activating and deactivating the splines but it doesn't work

[sour warren]

so I'm kind of sure I'm using the wrong nodes, because the logic makes sense

[lofty rapids]

what does the spline user paramater dropdown look like ?

i'm thinking you want to set the parameter

so you have it set to an actor, but you should be able to change this paramter

and it will change the actor

[sour warren]

you mean in the niagara scratch? there's nothing

so I have to create it in the splines blueprint?

[lofty rapids]

i'm, why does your dropdown show the search ?

thats a bug i've seen before

[sour warren]

probably because there is nothing there for it to use

how do I create tje spline user param in the blueprint?

[dark drum]

Does anyone know how I can get the current world/map as a soft object ref?

[lofty rapids]

and plug the new spline into actor

might work, but i'm not sure if thats the parameter name

i think it is

[sour warren]

oh ok so i have to use this for each spline and it gets triggered at every button push, right?

[lofty rapids]

try it first, make sure it works but yes at each time you switch

[sour warren]

ok it makes sense, thank you, I'm trying now

[lofty rapids]

if it doesn't work you can try #niagara

[lofty rapids]

this ? ^

[mental heart]

Hello , I Try to Implement a explosion With a knocback in Radius of the explosion and with a strength relative to how far you are from the center. I want to achieve something like the explosion of the mine from the kit of the Sniper from Risk of rain 2 for the people that want to have a idea of what i want for result.
For this i use the node LaunchCharacter but i Struggle to achieve a good result when i'm on the ground and the force is Horizontal to the ground, i know that it's because of the ground friction but i doesn't find any good tutorial on the Web that can help me to do this correctly, does anyone have a idea or some good tutorial for that ?

but for when i'm in the air already in motion i have a pretty good result

[sour warren]

It doesn't work, thank you I'll try there

[steep oyster]

Can you apply an Impulse on your character?

[outer brook]

Hello fellas.

Topic: Question about good tutorial for Moving Cubes in a 3D ThirdPerson ActionAdventure

Does anyone know a good tutorial for a "Move Cube" mechanic like the the old 3D Action Adventure games??

I've tried many custom-made versions but I am still not statisfied with the results. I was just wondering, is there any "Best Practice" or "Professional" method of moving a cube with a ThirdPerson Character? Keeping in mind obstacles, gravitation and maybe also rotation of the cube?

[mental heart]

I try to use it, but it's doesnt Work, do i need to have the Physic activated on my character ?

[steep oyster]

I think, but I dont know if that causes other problems with the character movement

[lofty rapids]

can't you just add some to the z, get it off the ground with the launch ?

you can also change the friction on the fly

[mental heart]

The problem is that if the explosion is over me i don't to go against the Force and for example if the explosion is opver me i want to be expulsed correctly to the ground

[frosty heron]

@dark drum What's the purpose? To save the soft reference to a save file?

[mental heart]

Cause to much issue to Activate the physics

[dark drum]

Pretty much yea. I'm wanting to keep track of what level the player is one so it can be opened to that level when reloading.

[frosty heron]

You can construct SoftObject with an object ref I think.

[steep oyster]

I think because the physics and movement component both implement falling, and they start fighting

[frosty heron]

TSoftObjectPtr<UWorld> CurrentWorld = GetWorld();

[dark drum]

I'm working in a BP only project at the moment. 😅

[frosty heron]

working on a plugin?

[dark drum]

This gets me the world object but it's only of type 'Object' so converting to soft ref just means its an 'object soft ref' which can't be used when trying to load the level.

[inland bluff]

our reconnection issue ended up being something simpler we were able to find on our client logs

[dark drum]

My current idea (still a work in progress), is to use a data asset that stores the soft ref as a string in a map where the value is the actual world soft ref. And then have a function that fetches it from the map.

As far as I can tell this seems to work but one would need to make sure the list is updated if the names are ever changed.

[frosty heron]

Yeah I don't know how to expose UWorld in blueprint alone.

it's freaking hidden in the variable detail panel.

[mental heart]

You can't have a Uworld ref in BP

[frosty heron]

you can.

[dark drum]

Its hidden everywhere lol. I can't even cast to world which would have solved my problem lol. I get why its hidden but there needs to be a way to atleast get the soft ref of the current level.

[frosty heron]

@mental heart just can't do it with bp alone.

[mental heart]

yep but i't not a UWorld

[frosty heron]

maybe epic don't trust designers, as they may end up loading levels that are not even loaded.

[mental heart]

It's a ref to the World Asset i think no ?

[frosty heron]

working 100% in bp sucks

[mental heart]

ok mybad i didn't think you can actually do that, i will try next time i need it

Thank for the Discoverry

[frosty heron]

I need this to save the level the player played last.

[dark drum]

With a bit of trickery you can also use the soft ref version in sets and maps.

[frosty heron]

seen people using Map with strings and all that to save 😦

[steep oyster]

I thought that's Get World Context

[frosty heron]

Imagine if they rename the map, the game will end up being borked, especially people that update the game.

[dark drum]

Yea, that's what I'm trying to avoid.

My current direction is probably the best I can come up with in BP only land. Still need to add them to a list but it'll get the search string automatically with a press of a button.

[lofty rapids]

this can get you the current map, is it the wrong type of reference ?

[frosty heron]

how do you even get to this point?

lol

@lofty rapids yeah we can drag and select promote to variable

@dark drum

[dark drum]

That errors for me when I connect it to an execution path.

[frosty heron]

this don't work?

oh wait

[dark drum]

Get level returns a 'ULevel' not a 'UWorld'.

[frosty heron]

i get what yyou mean

right

[lofty rapids]

something like this ?

get owner world, doesn't give you the current level, but the current world, if you open the level by instance it seems to take to the origin level

[dark drum]

That doesn't return anything for me.

This just prints none.

[lofty rapids]

hmm

[dark drum]

I'm not event sure what 'Typed Element World Interface' is. 😅

[lofty rapids]

"Get Owner World with ScriptElementTypeHandle is for scripting interfaces (like Python/Blueprint scripting), not regular gameplay code."
theres the issue, worth a shot lol

[lofty rapids]

are you wanting to just open the levels ? or you need the reference for other things ?

[lofty rapids]

it looks like "you simply cannot get in Blueprint without World Partition"

[dark drum]

Its so I can save the current level (as a soft ref) so when reloading, I can load the correct level.

[lofty rapids]

can't you just use the name ?

[dark drum]

I could but that runs the risk of things breaking if the name of the levels change. I don't fancy having to hunt every instance where the level name is used.

[lofty rapids]

unfortunately since your using only blueprints your limited

i would probably use a function in c++ for this it makes sense because it's easy in c++

sux to have to do c++ for say one thing, but it actually works in c++ from what i read online

or you could setup world partition

i have read that that is what the error for get world is all about

but a function that returns the current level reference as world object looks doable in c++

[spark steppe]

its a one liner!?

UFUNCTION(BlueprintPure, meta=(DefaultToSelf="Object"))
static TSoftObjectPtr<UWorld> GetWorld(UObject *Object){
  return IsValid(Object) ? Object->GetWorld() : nullptr;
}

put that in a UBlueprintFunctionLibrary and you should be good

[surreal peak]

return IsValid(Object) ? Object->GetWorld() : nullptr;

You could have gone for the actual one liner.

[spark steppe]

changed it, thanks. i need my caffeine 😄

[tight pollen]

I use Lumen in my project and I have low FPS, but in other project I also use Lumen but I have 110 fps

some ideas?

[dark drum]

Yea, it's not my project so i've got to keep to BP land for now. Either way, my solution isn't terrible, not perfect but it'll get the job done.

[tight pollen]

empty map only character

and my project:

does Memory usage matter that much?

[lofty rapids]

i wonder why it's so different, and wdym "default project" ? a template ?

[lofty rapids]

did you start from blank or a template ?

[tight pollen]

template

[lofty rapids]

is the "default project" a template ?

the same template ?

[tight pollen]

the same only expanded

[lofty rapids]

right, so what did you add ?

[tight pollen]

but see the CPU and GPU usage is practically the same

so either memory usage has an influence or some option in Project Settings

but I don't know what

profiler doesn't show me what exactly affects FPS

weird

on Low settings I have less FPS than on Cinematic

Low = 56-62 Cinematic = 70 - 75

ok, I need to play around with the options, thanks for the help

[granite nacelle]

child blueprint wont follow the logic that is in the parent blueprint, the problem is the child blueprint will attack once then starts to random roam but when the parent blueprint attacks it stays on the player until the player moves. the parent has Move to player, random roam, attack player custom events

[faint pasture]

yo what the hell

How can that not be valid

[sick sky]

i assume your talking about when this fire at the beginning of the game and not on leaving

[surreal peak]

Cause you foolishly believed Epic wouldn't trick you and give you two nodes to choose from.

Aka use the other EnhancedInputLocalPlayerSubsystem node that needs you to plug the Controller in.

[faint pasture]

yeah that did it, now the question is wtf does the other one do lol

[surreal peak]

I always wanted to check. I would assume it auto falls back to this and that's probably then expected to be the Controller or so.

It's probably the second one that just doesn't work in Blueprints.

    /**
     * Get a Subsystem of specified type
     */
    template <typename TSubsystemClass>
    TSubsystemClass* GetSubsystem() const
    {
        return SubsystemCollection.GetSubsystem<TSubsystemClass>(TSubsystemClass::StaticClass());
    }

    /**
     * Get a Subsystem of specified type from the provided LocalPlayer
     * returns nullptr if the Subsystem cannot be found or the LocalPlayer is null
     */
    template <typename TSubsystemClass>
    static FORCEINLINE TSubsystemClass* GetSubsystem(const ULocalPlayer* LocalPlayer)
    {
        if (LocalPlayer)
        {
            return LocalPlayer->GetSubsystem<TSubsystemClass>();
        }
        return nullptr;
    }

Although, it's the other way round, right.

The one with the input works.

Yeah honestly no clue. The nodes are auto generated after all.

So apparently there is a UK2Node_GetSubsystemFromPC node. And that node only works for ULocalPlayerSubsystems.

Ah, I found it. So the normal GetSubsystem node that most other Subsystems have is also supported for the ULocalPlayerSubsystem. It uses Get_FunctionName = GET_FUNCTION_NAME_CHECKED(USubsystemBlueprintLibrary, GetLocalPlayerSubsystem); for that one.

/*static*/ ULocalPlayerSubsystem* USubsystemBlueprintLibrary::GetLocalPlayerSubsystem(UObject* ContextObject, TSubclassOf<ULocalPlayerSubsystem> Class)
{
    const ULocalPlayer* LocalPlayer = nullptr;

    if (const UUserWidget* UserWidget = Cast<UUserWidget>(ContextObject))
    {
        LocalPlayer = UserWidget->GetOwningLocalPlayer();
    }
    else if (APlayerController* PlayerController = Cast<APlayerController>(ContextObject))
    {
        LocalPlayer = Cast<ULocalPlayer>(PlayerController->Player);
    }
    else
    {
        LocalPlayer = Cast<ULocalPlayer>(ContextObject);
    }

    if (LocalPlayer != nullptr)
    {
        return LocalPlayer->GetSubsystemBase(Class);
    }

    return nullptr;
}

Assuming the ContextObject is automatically passed into this (that's why the pin is not there and probably this), that node will only work in UserWidgets, PlayerControllers or LocalPlayers.

And no, it won't give you an error or prevent you from using it.

I'm trying to get the phys material of a surface when i click on it but always return None when printing the result. How can I fix this? When i hover over break hit result and phys mat of it, appears a messsage saying that i must set bReturnPhysicalMaterial to true in the queries params for this to be returned. Should i do anything about that?

[sharp ferry]

hi, it's difficult to teleport my character through a box collision into another room/level?

i just want to get close to a door, press E and my character teleport to that new starter point or something

[surreal peak]

I assume you'll need to do the trace manually instead of using the convenience function.

Cause you can't set the return phys material flag on the convenience one.

[surreal peak]

Depends a lot on your skill level tbh. If the other level is literally a different map, then you only need to open that map via OpenLevel when you interact with the door. Kinda requires a functioning interaction system, cause you would want the door to have the logic for that.

[sharp ferry]

yes because i dont want too much assets loading same time

i just want it to load the new map and leave the other behind

[surreal peak]

Yop

[cyan wren]

That worked! If im right though that would make it so the same velocity is applied regardless of mass though right? So like a car would move the same amount as an empty soda can if shot?

[fathom mica]

Is there anything I have to do to support subclassing a primary data asset and loading all of them or is this just not supported, i cant figure it out for the life of me. I have it working if i specify each subclass directly in the asset manager, with the _C and everything, but i just want to load all assets of the one main blueprint base class... am i using this wrong?

All in blueprints

Essentially I have a blueprint that subclasses primary data asset, call it BP_Item, then i have two subclasses of that BP_Weapon and BP_Armo. I'd like to load all BP_Item's from the asset manager. I can do it if i specify each as a different element in the asset manager, but not if i try to get all items.

In this example it's fine because it's just 2, but i don't want to do this for 60-100 things when they all inherit from BP_Item

[languid furnace]

how can i make a "turn in place" system on a FPS character , i tried looking up some tutorials but they were all TPS characters so they couldnt help much

[maiden wadi]

I feel like I did this at work when I put in a quick hacky bundle loading implementation. We aren't using BP classes of our data assets, but it should be the same. I can look in a few.

[maiden wadi]

Oh. No I made a function for it. Because I hit the same snag. 😬 I had to grab all of the types in the asset manager and for a given asset, find all assets who's base class were a child type of said asset's class.

Cause we have a CoreItemDefinition which we base everything off of, because it's got some basic UI data in it that we can use to display for any definition. But we specify them separately cause some systems use some types, other systems others, but here I needed them all and had to write that. :/

Alternatively, your other option is simply making a function to grab them all into an array of assetIDs maybe.

[distant grotto]

is there a way to add custom movement modes in blueprint?

[tight pollen]

Hello, how can I use Sphere Collision to check if it overlaps with PointLight?

can anyone help me with this??

[graceful sage]

could use an interface or just cast ig

specifically where?

[frosty heron]

Does a light have collision?

[sick sky]

no

[frosty heron]

Well overlap requires the object to have collision.

You can check bounds every tick maybe to handle the overlap your self.

[warm hare]

What would be the best way of adding a mechanic where my flashlight intensity decreases with the battery power?

[frosty heron]

Abbandoning flip flop for gameplay code would be a good start.

also don't cross pin.

[warm hare]

What would you recommend in place of flip flop?

[last peak]

Anything else ^^

[frosty heron]

just boolean

[last peak]

I dont know how you call your decrease battery event but i guess its running on a Timer?
If not create a timer by event set it to looping 1 sec and call it after you turned on your fl, connect it to a event "check battery" in there you check battery power and set the light intensity depending on the power

Eg, if battery power < 50 - set itensity (intensity / 2)

[warm hare]

So I created a Battery interface and added a function Decrease battery

[frosty heron]

is this code in your character blueprint?

[last peak]

Is the battery part of your flashlight bp? And is the flashlight attached to your player? If yes you dont even need the interface

[warm hare]

yes

[frosty heron]

Your battery logic should live inside your battery

what you are doing there is horrible design.

Ideally you have a component too to handle the interaction but for learning sake, you can handle the generic interaction in the character.

Interact->Object

and the object can implement interacted logic

[warm hare]

This is from a tutorial I followed. This is battery logic

[frosty heron]

so for a abttery it will decrease

[frosty heron]

ooof

is that really from a tutorial.

[last peak]

Hehe gorka style tutorial

[frosty heron]

Handling input outside a centralized object (character / controller) is terrible

[warm hare]

Yup

also after destroy actor nothing else matter

[frosty heron]

this tutorial is peak bad.

[warm hare]

So I see lol

[frosty heron]

I am not trying to be smug, you can ask in other channel or other people opinion.

[warm hare]

You are fine. i am learning there is a lot of better ways to do things in unreal. It seems I am running into ways that aren't the best

[frosty heron]

imo what you can do now is work on general interaction component.

your system should work with any interacted object

a battery can decrease/increase it's life.

an apple can be eaten.

[warm hare]

Okay cool.

[frosty heron]

a door can be opened, and so on.

Might want to look at some material for component.

there should be a decent interaction tutorial... though I don't know any.

maybe somone can share.

[warm hare]

Thank you for your help

[violet bison]

is it normal for bone references to be lost after delay after tick?
weird thing is the actor reference wasn't lost

[frosty heron]

Any reason why you want to delay there? I dont know when the cached value of a pure function is cleared but i am betting that cached value from pure function is safe to use only within the same frame.

If you must use delay, cache the result to a variable and use that variable instead.

[surreal peak]

:D Try doing that in C++ and you will get an idea as to why that can happen.

You are basically "lucky" that UE saves the data inside the Pin of a Node, as they are Objects themselves.
If you were to try and do that in C++, you'd notice that you can't just magically grab the return value of a function "a frame later", as the function body you would be working in has to finish "this frame". At which point you'd be forced to save the result to a variable. Which is precisely what you'd need to do in your case here too.

[cyan wren]

Im wanting to create an inertia based damage system, i am very new to unreal and im wondering if theres a way to make a blueprint that will apply to every physics object within my level? I really dont want to copy and paste the script into every single crate i place into a scene

[violet bison]

made projectile (client authorative ones) so used bind event to hit to send the event and if hs and damage back to player for next functions

and if the projectiles spawned right at opponent's face, the hit will be registered immediately when the event haven't binded

[surreal peak]

You could code your stuff in a Component and apply that to the Actors. You can add Components to Actors in the Scene fwiw. But the better option would be to have a base Actor Blueprint that your Boxes are based on.

[surreal peak]

Deferred Spawning in C++ would probably help with that, but in Blueprints you are stuck working around this.

You could save somewhere if the Event is bound or not, and if your overlap registered you can then handle that accordingly.

Or you stick with the frame delay, but then you have to cache the HitResult.

[cyan wren]

Alrighty, thank ya!

[proud magnet]

Hey can anyone give any insight to this question? Haven't gotten much from it and with how much its bottlenecking my gamethread i really want to figure it out. https://forums.unrealengine.com/t/how-to-disable-metahuman-face-setup-and-features/2590988

Does the meta human face have an anim BP set?

[proud magnet]

Wow, instant drop in gamethread time. Thank you so much for the suggestion!!!!

[frosty heron]

Wait how does delay play any role here?

Why does if you hit the head you have to wait a frame?

[maiden wadi]

Race conditions are fun. 😄

[dark drum]

The delay for the signal to reach the brain. 😉 100% realism.

[frosty heron]

Oh i didn't read the last bit properly.

but yeah just cache the result if you have to wait a frame.

[violet bison]

not if hit the head
is set the variable that indicate headshot first

if no delay, and the projectile is shot right point blank, the event isn't bind when the hit event triggers

[lofty rapids]

maybe delay untill next tick

i use this node sometimes to fix these issues

[frosty heron]

that's what he is using.

[lofty rapids]

i see it now lol, should of scrolled

[graceful sage]

Hey all. I have an issue with timers. It works fine when im running just one of these but if I click more than one button at a time it goes out of sync. I'm experimenting with using get world delta seconds but still issues. My question is how should I do this timer? I read timers are frame dependent but also I've read they aren't. Can anyone clear this up for me?

Would I benefit from doing this in c++?

[lofty rapids]

whyy are you dividing and multiplying the time ?

[graceful sage]

experimenting

[lofty rapids]

so usually what you can do

is multiply the number * delta

to get a frame independent value

[graceful sage]

what number

[lofty rapids]

whatever number you want to base on the frames

[graceful sage]

i tried multiplying by my "build rate"

[lofty rapids]

but honestly i think your timer doesn't need to multiply by delta for time

"timers in Unreal Engine are generally frame-rate independent"

"However, the precision of timers can be affected by significant frame rate drops"

[frosty heron]

The issue here is that calling SetTimer while it's still counting reset the timer.

that's why you have an issue when you click your button twice.

[graceful sage]

the issue is when theres more than one at a time the first ones progress finishes but the money isn't drained yet so the code when money left to complete is delayed and out of sync with the visual of the progress bar

[frosty heron]

So there are ways to go around this in bp.

you need to offload the timer to an independent object.

Actor component can be one of them.

[graceful sage]

thats not my issue i dont think

[frosty heron]

Or UObject.

[graceful sage]

im talking about a seperate instance of this widget

not clicking the same button

If i say click the command center then barracks the command center finishes its progress bar and the ready text appears delayed

by about 5 seconds or so

[graceful sage]

I could try this though?

[frosty heron]

I don't understand this logic.

[lofty rapids]

are you invalidating it when your monety to complete is <= zero ?

or wouldn't this just keep going ? when do you stop it ?

[frosty heron]

-1.f per call but at what rate?

[graceful sage]

#blueprint message

[graceful sage]

ill probaby need to show this to get it maybe?

[frosty heron]

AmountToSubtract = ValueToDecreaseOver1Second * DeltaTime

[graceful sage]

ive mainly been using .01 for build rate

[frosty heron]

if you are going to use delta time

[frosty heron]

if you gonna use delta time then use tick

otherwise take it away from your equation.

but for a progress bar, I would totally do it on tick.

So it update smoothly if my computer is capable of rendering fast FPS.

[lofty rapids]

finterp ftw

[frosty heron]

doing it on timer will gate the potential, regardless of the player's machine.

[graceful sage]

ok so I should update the material instance dynamic on tick?

[frosty heron]

you can take away the timer and just do the whole logic on tick.

though I can't guide you step by step, it's hard enough for me to read my own spaghetti, let alone someone elses.

Event Tick -> if bBuilding -> Evaluate (Go decrease your money or update the progress bar)

[lofty rapids]

using tick does involve some maths

but it will be smoother

[frosty heron]

simple math

Timer apart from not updating frequent enough, some people will put it at 0.0001 causing way more overhead than using tick.

and the less FPS the user have, the more they are tanking the timer.

If someone set a timer 0.01 second and a user FPS is soo bad it takes 1 second to render the next frame.
That timer would call the function 100 times.

100 times updating progress bar, in the same frame...

[maiden wadi]

For a performant, simple building system, you don't even really need tick except for the widget.

StartTime
TotalBuildTime
BuildSpeedMultiplier
CurrentEndTime

StartTime and CurrentEndTime can be set at build start based on TotalBuildTime and BuildSpeedMultipler. And if anything adjusts BuildSpeedMultiplier, you simply update your CurrentEndTimes.

Now the only thing you need is a single timer for the shortest build time.

Your UI and anything else can tick at it's own pace. You pay a lot less networking and CPU/MemoryWrite costs for state updates.

[graceful sage]

Trying to wrap my mind how I'd need to do the math lol

[maiden wadi]

Math for which part?

[graceful sage]

so should I be lerping the money down?

I'm just not sure how to use the delta time to do what I want I guess

[maiden wadi]

Do you know what delta time is?

[graceful sage]

I'm gonna have to look more into it I guess. Especially when I'm too tired lol

the time passed since last tick

[maiden wadi]

Right. So you know that someone who's running at 60 fps has a deltatime of like 0.01666666 or so.

Lets say you want to change the value by 10 per second.

You take your speed of 10 and multiply it by the deltatime. This gets you like 0.1666666

Now run this math 60 times as if you are passing 60 frames. Your value at the end is roughly 10.

The point being that the framerate is going to fluctuate from anything realistically between 20 to 200. That's a deltatime of anything between 0.05 to 0.005. But if you use this math. You'll always get a final value of 10 per real time second.

[dark drum]

That reminds me of a quest in GTA where you have to lay fuel on the ground to start a fire. If you're frame rate is too high you can't complete the quest because the fuel runs out before you get to where you need to go. Got to love that Fuel Per Second. 😅

[maiden wadi]

Yikes. 😬

[graceful sage]

So I need to subtract from the money by these values?

[dark drum]

I'm pretty sure it was done intentionally. 😅 A play on FPS. Thankfully it was a side quest lol.

[lofty rapids]

basically instead of adding or subtracting the number you want to increase by

multiply that number by delta time

also use finterp or ease if you can

[fallow umbra]

Hello, me have broblem

For a Pawn Actor, Skeletal Mesh with Physics Asset for collision as Root Component
Set Vehicle as Collision Preset

If I set the Vehicle=Ignore as default and then change it in-game to =Block it doesn't work at all, it changes nothing.

But if I do vice versa, Block as default and then in-game to Ignored it works without any issues, I can even toggle it back to block and it will work

What am I missing, I'm about to pull my hair, spent one hour to find out this 😅

[lunar sleet]

One hour is usually only half (or less) the time it takes to debug collision issues. Try ejecting and pausing at runtime and manually changing the checkboxes

[fallow umbra]

Thanks for the tip but that's the first thing I tried, it just automatically reverse back to Ignore, probably because i use smoothsync (client authority) for the player vehicle.

It's just weird how it works one way but not the otherway,
eitherway will do block default, ignore on begin play and set block when i need too

What's the approach to having a single parent class for all characters in the game, and not having it have a billion components? Is having the AIController and PlayerController add components to the character on possess decent?

PlayerController adding camera, AIController adding sensing components, etc

[maiden wadi]

IMO, I tend not to care so much. If you need the performance of less component, you're probably already pushing for ECS territory. And there's plenty of systems where you can benefit as a player from the same stuff that AI uses for perception and the like.

For things like the cameras on the pawns, that's easily fixed by just not having one and putting in a decent camera system that doesn't need the components.

im trying to give a crate a health bar, target self doesnt work and i have no idea how to make the mesh link at all

been stuck for a bit

[frosty heron]

How do you want to display the health bar? start by doing the widget first.

at the end of the day, widget just read value from the owner (in this case, the static mesh).

[cyan wren]

im gonna give a wooden crate damage states, currently i cant assign the actual health value to the shootable mesh i have in my scene

i dont plan to have a visible healthbar and right now my visualization is debug text

[frosty heron]

Why not? are you saying your print string is incorrect?

at the start the woodcrate should have a hp of 25.

On damage taken, it should be current hp - damage.

[cyan wren]

im tired, i didnt mean to say bar lol, i meant to say pool* my bad

[frosty heron]

well anyway, what's the current issue.

are you not getting correct values on your hp?

[cyan wren]

im not currently getting any values is the issue, i dont think its referencing properly. when i shoot it, it should apply damage but it does nothing

[frosty heron]

So your TakeDamage event is never called, is that the issue?

need more info here. Show the code where you apply damage.

[cyan wren]

hold on, sorry couldve done this better

hitscan applies damage to hit objects (or it should)

[frosty heron]

does it apply the impulse?

you may need to ensure if the hit actor was ever the actor you are trying to hit, you can do this by print string the HitActor.

[cyan wren]

i have it print the hit actor, it applies impulse and everything reads fine

im getting this runtime error when i shoot at my crate

[frosty heron]

The instance doesn't have an owner.

so your event is never binded.

[cyan wren]

the node says it is targeting self, but i dont know what to change it to

[dark drum]

You need to use the standard 'onAnyDamage' event. It's available on all actors. (Something along those lines)

For additional context, it just an event you can implement.

[frosty heron]

Well let it bind to self, I suppose.

Also reading online it seems you need to specify the damage causer. Just make it the object that is doing the line trace.

[cyan wren]

THAT TOOK SO LONG, I DIDNT KNOW YOU COULD JUST DO THAT

[cyan wren]

thank you both, you guys are badass

[frosty heron]

well I am just guessing not much of a help but nice that you got it working. Personally for me, unreal damage system is soo ancient that no one uses it for a project outside game jam imo.
