blueprint

[sudden tusk]

its inside of a function, i create a temp holding variable - but this set texture node needs a target

and i cannot assign a target before it is set

[compact vapor]

Thanks for the advice!

[fleet cedar]

@orchid star That's interesting, but I don't want a single tag applied to it, I want a float value... would I just use lots of tags?

[sudden tusk]

how do i use that to set the image then?

[viscid musk]

I will check this person out. Thank you

[orchid star]

plug the npc image to target

and remove set npc image

[sudden tusk]

ok

[orchid star]

you can create function library and set the variable values there

like lets say

it has

Tanky tag

[sudden tusk]

it doesnt take the type

[orchid star]

you use this value with this library

[sudden tusk]

@fleet cedar it doesnt take the type

[orchid star]

then npcimage is not exactly image widget is it then

[fleet cedar]

Would this work if I have 1000 different values?

[sudden tusk]

its a map of string; 2d texture

[orchid star]

this is not

[sudden tusk]

trying to implement a tab target system; when i press tab - need to display the npc stats including image, have figured the other part this image into widget is not working

[orchid star]

this is raw reference

try using 2dtexture

let me check what it was called

hold onm

[sudden tusk]

yes it is a 2d texture

just need this bitmap into the image box on the widget like here

[orchid star]

ooh

right

my bad

what is npcimage

class

in widget

?

[sudden tusk]

its a map of integer to 2d texture

[orchid star]

no

[orchid star]

this

npc image

what is it

[sudden tusk]

its a variable in widget class

[burnt nest]

Could you maybe press enter when you actually finished typing? 🤔

[sudden tusk]

i load this manually - by defining the variable in editor, and then added the bitmaps from content library

[orchid star]

then if you want to change the image you use this set brush from texture on the image widget

[sudden tusk]

thats what google told me.. but just not sure, also as i mentioned before, what is the target on this node

[orchid star]

Image Widget

[analog perch]

i think you just need to plug in the actual image

[sudden tusk]

image is not compatible with 2d texture

[orchid star]

what is compatible with 2dtexture then

what is the widget image

on your widget designer

you will use that to set brush from texture

[sudden tusk]

do i use it like this -

this gives me an error on play - as tempvariable is tried to be accessed before it is set

and it doesnt work anyway

[orchid star]

I dont understand what is the problem

you are missing the point

[orchid star]

it is what it is

[sudden tusk]

this is my ui widget

my question is - how do i load this 2d image into this box?

[orchid star]

and you are telling me you cannot plug npcimage to target

[sudden tusk]

npc image - is a map; i get the first element of it, the value of that is a 2D Texture

i get that also in runtime; - till that part it is working

[orchid star]

dude

you need better naming

[sudden tusk]

only part missing, - is how to convert the 2d texture, and load into widget image box

[orchid star]

this is image widget

[still needle]

anyone knows how to enable/disable cloud shadows in blueprint??

im using volumetric clouds

there is an option in Directional Light to do it but I want to do in a blueprint

[sudden tusk]

@orchid star thanks for helping me - i got what you said

[azure bolt]

Hey I'm adding a widget to viewport when i collide with a box collison, which works, but it doens't work when i leave the box. The code runs, but it doesn't remove from parent... anyone know whats going on here?

[dawn gazelle]

Set the "owning player" to the player controller when you're creating it. See if that helps.

[orchid star]

it probably wont

try to see where it fails

put a watch on remove from parent

and check if the reference is right, or if even comes to that

[azure bolt]

It doesn't fail thats the thing

The code runs

[orchid star]

check the reference

you are creating the widget

setting it

but you are adding it to viewport

from create widget pin

maybe try connecting the variable instead

[azure bolt]

Yeah tried that too, didn't seem to work

[orchid star]

so

the code comes to remove from parent

right ?

[azure bolt]

Yep, it runs the whole thing

[orchid star]

tbh

this is wrong aproach anyways

overlap

might be getting called twice

and dropping the first reference

and therefore not get removed

use print s to see if overlap happens twice

[azure bolt]

Yeah your right, its running 2-3 times

I'll try putting an if branch in

[orchid garden]

even if your using a overlap - you can check to see if the widget exists before adding a new one.

[orchid star]

maybe better

[orchid star]

or yeah you can do that as well

but try to control it more reliably

dont handle widgets outside of controller

or maybe pawn

[orchid garden]

what it sounds like is they are adding the widget - setting the var, the event gets triggered a second time and the widget is added again - overwriting the var for the first one.

the other approach would be save the widget reference to a array (expecially if it can show more then one at the same time).

personally for popup widgets, i use a single widget thats part of the hud, and only the information on that widget gets changed during the 'on overlap' on the exit from the overlap it just hides the widget.

this resolves the problem with overlap being triggered twice or more for me, and seems to be accurate for whats being hit.

[azure bolt]

Ah for me making the widgets was giving me a headache so i just made what i wanted this one to look like in photoshop. So its pretty static. but yeah. Is hiding/Showing less resource intensive that remove from parent/add to viewport?

[orchid garden]

depends on how complex your widgets are. widgets are only player based so its only going to effect the client its running on.

[azure bolt]

Yeah its not really the most complex thing in the world

[orchid garden]

yep thats a pretty basic widget, shouldn't impact anything.

i'll show ya mine here in a sec, waiting on project to load.

thats my overlap widget, has 3 text areas that get changed and the little white box is a graphic atm for the key to be pressed. The top one only shows if there is a secondary action key for the item.

[azure bolt]

Pretty smart

[orchid garden]

i also use the little white box to display a graphic sometimes:

im going to be remaking my project so this one has litterally been turned into a test project now.

but all in all its a multi-function pop-up widget slim design so i can use and reuse depending on what a trace / overlap hits.

[limpid bramble]

for some reason i cant look up or down

i can look side to side but not up or down

i do every thing i did for other games and still doesnt work

i do everything the video does too

[trim matrix]

hey I have a boolean in one class and I want accees its state in another blueprint though I have no target I just want to put the boolean value from class a to b; How could I do it because with casting the target part isnt working

[prime stump]

Hey, can a custom event be called from a child BP? I know functions can but im using a timeline which cant be put in a function so i cant use them

nvm figured it out

[fierce birch]

Hello all. im currently encountering an issue with enemy respawn logic that i made. I cant get the array of enemies to update. I was wondering if you could drag out of the spawn actor

[sonic pine]

Hiho to use a function Library i have to set a cast from Widget to this library, dont i?

[lusty elbow]

Functions from a function library are available everywhere. It's macros that are tied to a specific class

[lusty elbow]

I always forget to ping

[sonic pine]

im also thiink like that but i will get an errow about the Func Lib ^^

And this function is a function from the SkillFuncLibrary ^^

so i think he want to have a cast or something like that ^^

[lusty elbow]

Judging from the icon at the top left of the node, it's a function from a blueprint called "Skill Func Lib", but it's not from a BFL (a Blueprint Function Library). Please, double check that.

[sonic pine]

its a blueprint function

[lusty elbow]

Check the Blueprint type. "Normal" vs "Function Library"

Good news is, you can easily copy paste the functions from one to another. Not talking about copy pasting the blueprint code, but the functions directly

[sonic pine]

the function + code?

That would be nice in my Library i have 311 Skills so 311 Functions XD

[lusty elbow]

Damn! I don't know if you can select several of them at the same time

Doesn't look like it

But

[desert juniper]

this sounds like really smelly code

you have clearly architected this incorrectly.

[lusty elbow]

In the function list on the left on the origin BP, right click the relevant function. Copy. Then go to the destination BFL and Ctr+V. It should appear on the left, on the function list

[desert juniper]

you should most likely have a single function that modifies any of those skills

[lusty elbow]

If you're going to refactor in the original BP, you'll have an easier time moving them

I wonder if there's an easier way

[sonic pine]

its ok thanks ^^

[sonic pine]

i was asking 3 or more times ^^

[rose gull]

Can someone help me up with a lill system in my project-
I basically want to make a battlefield style loadout system where you can chose the weapon you wanna spawn with

[white lynx]

Is there a way to open the same blueprint multiple times? I want to transfer settings from one struct to another (which are incompatible, so can't copy them) in their components' defaults

[rose gull]

Store it in a variable?

[sonic pine]

I have already asked several times about the skills, either there was no answer at all or I was referred to the GAS channel. Unfortunately I don't use GAS, I built everything myself and have now set over 200 skills so I won't start from scratch ^^

I am currently changing each skill individually in the skill tree

[white lynx]

Nani?

I already have the variables - I want to transfer their settings from Property A to Property B

but the structs are incompatible, so I can't copy - paste them

[maiden wadi]

In a datatable, or?

[desert juniper]

you can open the same project up twice

[white lynx]

in their components' defaults

[white lynx]

that is a huge ooof

I guess I'll just duplicate the BP then

then delete when done

[rose gull]

I had the same problem

I was using actor as a child in another actor

And i changed the actor to one of its children overtime but it somehow never changed the properties

[desert juniper]

that's unfortunate that you weren't able to be helped. but I'd highly recommend you change that now 🙂 or you'll end up with much bigger headaches down the road

what do the skills look like? have an example BP?

[rose gull]

Does anyone know how to do this?

[sonic pine]

second^^

[desert juniper]

that's an extremely vague question with no specific answer. you'll want to start small. look up creating an inventory system first

[rose gull]

Why would i make an inventory system?

Think of it as a death match mp based game

I just want to change the primary weapon and its properties

[desert juniper]

a loadout is a collection of items, stored and equipped in a certain manner

i.e.: an inventory

[rose gull]

Well true

But im still confused

[desert juniper]

and an equipment inventory is just an extension of that inventory system

[rose gull]

Can i not use a main BP and just have the mesh and stuff stored in enums

[desert juniper]

you can. won't be as extensible. but if you're scope is pretty small, then this will work

not the enums, but just having all the properties on the character

[rose gull]

I tried to do it

But it sucked

Hm alrighty i guess ill go try again

Thnx

[maiden wadi]

I think you mean structs? You can't store anything but 256 whole numbers in Enums.

[hushed badge]

anyone knows whats wrong with this ? i cant look up or down with the mouse

[orchid star]

check if your spring arm uses controller rotation

[hushed badge]

where do i check?

[orchid star]

spring arm

how is your camera setup ?

[hushed badge]

its in my character bp i know

but where is the controller rotation thing?

found it

its not checked

should i check it?

[orchid star]

yes

[hushed badge]

nice

thanks alot

btw is how is this ? is this even gona work?

[orchid star]

idk

[hushed badge]

im still knew to these things, i ges i have to fail to learn

[late blaze]

Does anyone know how to take a wave player in a sound cue and decide a looping point to start and then one looping point to end?

[orchid garden]

idle->walking->jogging can all be controlled by a single blendspace, seems to be how most people do it, even for straffing and walking backward.

[barren fern]

Hey guys, I had a question that I was wondering if you had the answer to because my own research has left me unsure. I am creating a level editor type of game where you can drag in actors and place them in the world. One of the tedious tasks I have is needing to create UI buttons for each of the objects you can place which takes up time considering there is hundresds.

My question is, UE4 already renders an image in the editor when I am looking at the BP in its folder. Is there a way to take that image and turn it into a texture that could be applied to a button?

[orchid garden]

something like this maybe? https://marketplace-website-node-launcher-prod.ol.epicgames.com/ue/marketplace/en-US/product/thumbnailer-lite

lite version is free, regular version is 14.99

[barren fern]

Thanks @orchid garden the other plugins in the store next to this one look exactly like what I need. It will save me a ton of time instead of having to manually create them myself.

[tight schooner]

Dunno offhand but try #audio

[hushed badge]

i have a blend space made dont know how to use it yet

[grave relic]

Is there someone that is handy with interfaces? I'm having a controller that controls the time of day. It takes different times of day and stores them as ints, so sun rise is 0, morning is 1 etc. And i want the the sun-controller to send out to all interface users that this currently the time of day is X. So for test i have a actor that has the Day time output, but the script never reaches the actor from the controller.

[trim matrix]

@grave relic On the sun controller, when you call DayTimeOutPut, you need to specificly tell the controller which actor to send the data to.

Right now when you call DayTimeOutPut

on the sun controller,

The sun controller is trying to send that time data to itself

since the target is "self"

you need to get a reference to that specific blooming flower within your level, plug that into the "target" input on the DayTimeOutPut

I belive your missunderstanding how interfaces work

you dont just call the interface funtion and it magicly sends the data to all interface users. You still need to specify a reference.

[grave relic]

Okey i see, im planing of having a lot of entities tied to this controller. So was thinking of an interface to broadcast to every user of the interface. Cause i know i can just put in a target, the problem is that im gonna have 100+ entities that are going to be dependent on the sun controller. And it was my understanding that a interface is a best way to achieve this.

[trim matrix]

Interfaces could be very usefull there yes. But not in the way I believe your thinking.

[grave relic]

So basically i need a way to get this message to every entities dependent on the time of day, and it was my understanding that an interface would be best for this. But seems i was wrong 😮 Any other ideas? Would really appreciate the help ❤️

[trim matrix]

Nono your kinda right here.

yes interfaces would help you alot

Its just

Well first off just to make sure, do you understand what I mean when i say "reference" ?

just to be clear xD.

[grave relic]

I do, im aware of most of the basics, just trying to learn interfaces 🙂

[trim matrix]

okok sorry then but just to make sure lol

kk so an interface isnt some call that automaticly sends out the event to all its users

[grave relic]

Np! if you dont know that i know you cant tell me 😛

[trim matrix]

its just like calling direct logic on something.

you need to have a reference to the actor to call logic on it

Though the thing that makes interfaces special is that they can be used to call the same logic, on many many different types of actors.

anyways,

in your case. I would store a reference to every actor that needs to that time of day information.

Then, loop through them all.

and directly call that interface funtion on each of them

just like you would have todo if you were not using an interface.

[grave relic]

So for example i could use get all actor with interface, store them in a array ref, and then when im gonna tell everyone what time of day it is, use the ref and plug it into the Day time output?

[trim matrix]

yea

that would work mhm

That would be the way to accomplish this using an interface

[grave relic]

But then im thining what type of reference i should use. Cause the Day time output requires a reference of type interface, while the get all actors makes an array of actors. And the reference is incompatible, and i don't think there is a way of converting actor to interface ref

[trim matrix]

oh

actor references still yes

Try dragging off one of those actor references

and trying the name of the interface funtion

[spark steppe]

also this is not a broadcast or whatever

if you use get all actors of class, it's more like a wild guess

[grave relic]

Oh right forgot you can do that! That will solve it, thx for the help Morgana 🙂

[trim matrix]

The reason your seeing it require a interface type input is because the SunController also has the interface implemented

[spark steppe]

your actors could subscribe to a event dispatcher on your daytime controller

[trim matrix]

you were using the version of the interface function that exists on the SunController,

[spark steppe]

so your daytime controller has a event dispatcher named onTimeChanged for example, and notifies everyone that is subscribed on time changes

[trim matrix]

yea that to but he asked about interfaces xD

trying to learn them

[trim matrix]

theres a specific get all actors with X interface implemented.

[grave relic]

Ah i see would you say that i should use event dispacher intsteed @spark steppe ?

[trim matrix]

tbh that would also be a great solution to

although both would work

[spark steppe]

that's what i would do, it was just a suggestion

[trim matrix]

same xD

[grave relic]

I see, you are a great teacher Morgana, feel safer about interfaces atleast ^^

[trim matrix]

[grave relic]

Will lookl into event dispatchers, and more into interfaces, thx for the help both of you ^^

[trim matrix]

Good luck

[grave relic]

[limpid bramble]

i coded everything as the video and what i have done in that past said and it wont work

it wont let me look up and down

thats the problem

[hushed badge]

you mean the camera?

[limpid bramble]

i can look side to side

but not up or down

i can send a video

[hushed badge]

had the same thing earlier

[limpid bramble]

did you fix it?

[hushed badge]

yeah

[limpid bramble]

how

i have been trying to figure this out for housr

hours

[hushed badge]

someone here told me to select the camera or the spring arm and then check the controller rotation

it worked for me

[limpid bramble]

where would i find the controller rotation

@hushed badge

[hushed badge]

you use code? or blueprints?

[limpid bramble]

blueprints

[hushed badge]

you could just send a screenshot

[limpid bramble]

there is my movement

i figured it out

[hushed badge]

on the right scroll down

[limpid bramble]

thank you

[hushed badge]

ohhhh

np

did it work?

[limpid bramble]

YES

i have been working for hours to fix this

thank you so much

i was going to restart the whole thing

[hushed badge]

waw i ges you and i are at the same pace lol next i have to do blend spaces

[limpid bramble]

nice

im the only dev in a team so its hard to do everything

lmao

[hushed badge]

same

[limpid bramble]

one other person is learning so hope it helps

[hushed badge]

hope so gl !!

[normal stream]

okay i've been punching around this problem for about 2 hours; I'm trying to rig up a really basic projectile collision logic. Right now I've just got a basic projectile BP with a collision cube, a static mesh, and a particle system that spawns on hit.

In the projectile's collision component, if I turn on 'world dynamic' to overlap, the projectiles spawn and instantly count as hitting something.

[woeful pelican]

Are you checking if the 'other actor' in the hit/overlap is what you want it to hit?

Something like this.

[normal stream]

i'm currently using the content examples, which hooks into a scene component variable of 'Projectile Owner', which I think is also incorrect...

[woeful pelican]

Mind if you take a screenshot of the blueprint?

[woeful pelican]

I'd suggest doing something like this to find out what is making it destroyed. You don't have to do the casting, just put the print string after your branch.

[ornate folio]

Anyone know of a way in BP I could check for if the player simply moved the camera and also track the speed of that camera movement?

[normal stream]

it's hitting bpPlayerShipPawn...

[gentle urchin]

Get camera manager -> get velocity

[normal stream]

i have the projectiles spawning through two scene components (two hardpoints beneath the wings), no matter where i move them, they seem to be hitting something.

the scene components are nested under the static mesh

[woeful pelican]

Does the projectile owner variable have the instigator in it when it overlaps?

[normal stream]

which is under a box collider

i don't think so...

[woeful pelican]

That'll be why that's occuring

[normal stream]

Hmm. That's interesting.

so i put down in the BP projectile event graph, EventBegin Play > 'set owner to Projectile Owner'

and now the other-actor print is saying it's hitting itself

[woeful pelican]

This is what I have in a projectile I made before. Haven't tested it much but it should work.

Either make this populate the variable, or check it upon overlap if the former doesn't work

I also have a check in the projectile to ignore if it hits or overlaps itself

[normal stream]

Hmm. I should stress that I am extremely inexperienced.

[woeful pelican]

Same lol

[normal stream]

so I'm not sure where the Is Valid check is going, for example

[woeful pelican]

Oh, one sec

Not sure you need to do this though

This might work too

Not sure which is best performance wise

And if BeginPlay always occurs before hit/overlap

[zealous sundial]

Sorry

but, what the hell ?

[tight schooner]

Not sure. Is it a function? It could be that it must "return", in which case you can add another "return node" for clarity

[zealous sundial]

it's a macro

but it doesn't matter, this is a engine bug here

and... a huge one tbh.

[normal stream]

Hmm. Might have to start the projecitle logic from scratch. Oh well, learning by repetition is learning

[supple dome]

bp debugger is kinda broken unfortunatelly

[spark steppe]

debugger doesnt always tell the truth^

[supple dome]

just trust your code when that happens i guess

[fleet cedar]

Is there a volume that I can use to block sphere traces that are inside it?

[supple dome]

like to just block the channel? that can be set with any volume, whats the use case?

[fleet cedar]

I guess because I am using a multi trace it passes through it?

[supple dome]

multi traces should stop at the first blocking hit

[fleet cedar]

Oh? Hmmm

[normal stream]

thank you for chiming in with advice. It was appreciated!

[fleet cedar]

So if I have 20 colliders and put a large box over them and set it to block all, it shouldn't hit the ones inside?

[woeful pelican]

Yeah for the moment my code actually doesn't check against the instigator, collision wise. It just spawns outside of the pawn geometry and hope it doesn't collide

[normal stream]

gotcha

[woeful pelican]

But the examples I linked should be ways to check it

[supple dome]

yea, however i dont know how it will behave when the trace starts already penetrating (if you are inside said box)

[dusky prairie]

Hey there, was trying to fix this last night but I couldn't figure it out. I've been looking more and in this timeline, after activating once, it will stop at seemingly random values. Does anyone know why my timeline will stop randomly at different points halfway through? I will attach screenshots of BP below, thank you 🙂

[formal cedar]

Hey guys im kinda new to unreal engine but I was wondering if there is a certain tutorial or asset that can make weapons that only kill certain enemies>

for example, I want this pistol to kill every enemy except these two

[flint vector]

are all enemy's the same class?

[formal cedar]

yes I am using the AI tookit NPCs

[flint vector]

oh

that makes it a little harder

[formal cedar]

what if the two enemies were not NPCs from the toolkit?

I could use render targets for an alternative option, any tutorials on how to use render targets for spawning in game and clearing render targets with certain weapons?

I basically want to create a mop that I can hit people with and also clean puddles

[vapid ibex]

I've got my millipede npc mostly working:
https://i.gyazo.com/c34f2a3e7b91463c7c188949d2dd7299.mp4

I'd like to next implement self-collision check, so that it wouldn't cross it's own tail.

But I dunno how.

Right now it moves by just constantly feeding movement input along the forward vector of the head segment, and head segment slowly turns to look at whatever target destination location currently is - there's no AI controller in the thing.
It generates spline path behind it, that's used to lay out the rest of the body segments. It's quite simple setup, but I don't know how to factor in a self-collision check without tossing away the current movement setup, which ensures that velocity vector is never changed sharply, like it does with the regular AI controller.

I guess body segments should "deflect" the head away from them, but how can I go about that?

[weary crown]

I'm using BLUI to do HTML UI in certain elements of my project. How would I go about calling functions somewhere when the user clicks a button on the ui?

[hallow sentinel]

So really general question (maybe, at least I hope so) and apologize if this is the wrong place for this question. But I am fuzzy on when I should use pawn and when I should use character. The bit that confuses me is that character specifically says for bipedal implementations, yet I have so much trouble finding good resources for how to correctly implement movement on a pawn without the CharacterMovementComponent. Lets say in the context of a generic slime monster in an RPG, would you make your blueprint from pawn or from character?

[thorny marsh]

Character can generally be used for most types of moving NPCs.

Even something like a Deer could be a Character, only the visual element is a quadruped.

[hallow sentinel]

So would really the main distinction be if you needed custom movement or something that falls outside the realm of the CMC?

[thorny marsh]

Yes, another reason would be optimization.

[hallow sentinel]

or something not "living"

[thorny marsh]

CMC is quite advanced.

It has a lot of functionality you may not need, so you would have reason to create your own minimalist movement component that achieves only what you need it to do.

[thorny marsh]

Whether its living or dead shouldnt have anything to do with it.

[hallow sentinel]

yeah i guess that was a bad way to phrase it.

do you know any good resources/examples of using a movement component on a pawn? google/youtube just like to spit out videos using the character

[orchid garden]

technically if your character pawn is using a capsule component, wouldn't the CMC work the same for it?

[glass crypt]

Hi, I'm running into a really strange issue with traces on my foliage. I'm doing a box trace that moves across the landscape and spawns fire emitters on the foliage it hits but for some reason foliage on the corner of the landscape which is not being hit by the trace is also spawning emitters. Anyone know what's going on? Thank you.

[surreal peak]

Is it a 1 to 1 thing?

If you only trace one and set it on fire, does it exactly burn one on the corner?

Might be sharing data somehow?

[dire atlas]

Hello everyone, can you give me a hotkey for aligning nodes and connecting lines?

[dire atlas]

Is this a Bootstrap grid?

[atomic salmon]

@dire atlas select and hit "Q"

[fallen glade]

Hello all! I want to keep this macro as is and use the "Spline component" only when "Single" is true .... why am I getting these errors even when "Single" is false?

[fallen glade]

that looks sick

[surreal peak]

Can you show the whole thing?

[fallen glade]

this is the whole macro

[surreal peak]

What is "SplineMaterialGradient"?

[fallen glade]

it's the name of the macro

[surreal peak]

Hm, it's trying to fall back to self on that SplineComponent pin

Which is obviously wrong since that's probably some actor

So it's not about the boolean

[fallen glade]

yeah it is .... maybe I should just recreate it if it shouldn't happen

[surreal peak]

But about the unconnected SplineComponent Pin

You could just make two macros if it's not solvable

[fallen glade]

so I can't have the empty pins just hanging there if unused?

[surreal peak]

Apparently not

Idk how Macros work internally

[fallen glade]

oh ok, thank you 🙂

[surreal peak]

Maybe there is some setting on the Input

But it tries to use "self/this", and that is whereever you have that macro in

[fallen glade]

i'll try to make it a function first and then separate them If I can't thank you for your time, very helpful as usual @surreal peak 🙂 ❤️ 🙏

[fallen glade]

you could spawn some sort of collision spheres behind you and try to avoid them by using some whisker traces on the head ?

[atomic salmon]

@fallen glade you need to connect something to the input Spline Component

Even if the error appears inside the Macro it is actually in the way you call it

[fallen glade]

It's giving me no problems in a function ... is it still bad?

[atomic salmon]

Spline Component is the name of the input pin, it doesn't mean a reference to Spline Component is passed to it, you need to actually connect the reference to the pin

Macros are just replaced by the contained code when you compile the BP (a bit like C++ macros)

[fallen glade]

so they need everything to be connected to work .... makes sense

[atomic salmon]

If the function acts on a Target and the target is the actor itself, then it will work with the default (this)

[atomic salmon]

Correct. Otherwise it will just carry on a null reference which will produce the error

[fallen glade]

I see, so why is the same function not giving me errors?

[atomic salmon]

@fallen glade probably it is using the Spline Component reference as target or it has internalized the reference when you have created the function. Can you show the function?

[fallen glade]

I just copied the code over, here:

[atomic salmon]

@fallen glade and can you show how you call that function?

From the EventGraph

[fallen glade]

here: and

here

[atomic salmon]

You are actually passing something as New Param 1 (being blue I assume it is a reference), that's why it works. If you do the same with the Macro it will work as well.

[fallen glade]

the bottom one was fine as a macro, the top one was giving me errors

[atomic salmon]

The top one should also give you errors as function honestly, because you are not passing any reference to it.

[fallen glade]

haha no idea what's going on 😛 I might separate them just to be correct...

[atomic salmon]

Bottom one works as functions and as a macro because you are passing all the right arguments to it.

[fallen glade]

I assume that should always be the case right?

[atomic salmon]

Ok let me clarify this.

A Macro has to be valid at compile time. That includes a proper connection of the inputs since, as said earlier, the actual code is just replaced with the code contained in the macro.

For a function it is different. It is ok to pass a null reference to a function. In that case the unconnected PIN is fine at compile time, it means you want to pass a null reference to that function and the function may be fine with it.

Then the function will fail at runtime

in your case

[fallen glade]

I see, didn't know any of that. Thank you for your time explaining things to me !!! 🙏 ❤️ @atomic salmon

You are welcome. 🙂

does anyone know how to get the player controller number? i can't seem to figure out how, but i can get it if i'm in an external blueprint.

like epic games launcher has in app update

I literally searched whole google for that but only got nothing

[trim matrix]

can we do it

because i know about patching

but i dont wanna use that

i wanna have update option like epic games

[maiden wadi]

You're not going to be able to do that in Blueprint. Even in C++ that is going to be a rather technical topic for in application updating.

Whats the difference

[torn kettle]

:triangular_flag_on_post: ROYALKINGSJ#2266 received strike 2. As a result, they were muted for 1 hour.

[maiden wadi]

@dense citrus Well.. that happened. Anyhow. Normally controllers are numbered in the order they're created in. In Singleplayer you'll always only have PlayerController 0. In Networking code, this is often pretty useless because you don't really rely on the order of the controllers but the way they connect with other objects.

[dense citrus]

@maiden wadi what's a good way to dictate players then? i'm using a few different player characters, using the same blueprint to make a sorta multiplayer, but the damage is applied to all characters, not just one which is a big ole issue for reasons i'm sure you can imaggine

[maiden wadi]

What is the damage from?

[dense citrus]

it's from an object in game using a blueprint interface @maiden wadi

[maiden wadi]

But how is the object supposed to damage the players? Is it like an AoE, projectile, etc?

[dense citrus]

oh, under this instance, it's a box collission, which sends to the bpInt numbers i want like dmg and such, then to the player bp

[maiden wadi]

So when their character walks into it?

[dense citrus]

yep, beginOverlap

[maiden wadi]

In that case you can get the correct controller by getting the overlapping Pawn, and doing GetController, and cast it to your player controller type.

[dense citrus]

i have done that first bit, butt on the last i cannot seem to get it (thus my issue) is there anything obvious I'm missing? this is my first time doing this

[maiden wadi]

You probably also want to only do this on the server.

[visual vigil]

how to make your gun along with your entire arm point towards a target

[maiden wadi]

@visual vigil Depends on how perfectly accurate you want it. Most often the illusion of this is created with 1D or 2D aim offsets, which are just blendspace animations driven by control rotations more or less.

[dire atlas]

Thanks🤝

[visual vigil]

i wana do like the one in old tombraider games when her individual hands can aim to different targets

tried using look at function but didnt give good results bec bone transforms are inverted

Hi. Is there a way to make the editor break execution at a node that generates a warning like it breaks execution at errors?

[terse latch]

Might there be anyone who has worked with superior rpg? I ran into a trouble some problem with the targeting thing. I want to disable it (for now anyway). But even tho I set the input keys to none. When I hit Q it locks the mouse up if aiming at a "enemy".

[icy dragon]

Breakpoints exists.

[slate moat]

well, thank you. the thing is that the warning I get involves a node that is called tens of times at startup but throws a warning just twice. I would rather not spend 2 hours going through each call to see why " Attempted to access index -1 from array of length 0".

[maiden wadi]

It would probably be easier to find out why your accessor is -1.

Hi, I'm trying to teleport a character
Does anyone have any idea how to get a teleport position so that the character will not fall off
For example if you teleport to the edge of the object then the coordinate will change so that the character won't fall off

You could probably project it to navmesh, that might give it enough space for it to not be at the edge

@earnest tangle nice idea, i will try thx

@earnest tangle wow, its perfect

Hello Everyone,
i'm working on a shooter game project and it has 7-8 maps . i make a build for ANDROID, and it's working fine But when i make a build for IOS It's only loading the default maps nothing else working except the default map . i can't Switch to other maps, they are not opening . please help.

[runic terrace]

Did you specify which maps to include in the build? It must be in the Project Settings - Packaging

[runic terrace]

Expand the first dropdown in Project Settings -> Packaging, you should see this

[thorny glen]

Yeah i include all the maps in here.

Still not working

[runic terrace]

Not sure then, I didn't work with IOS before

[trim matrix]

May I ask a question? I found that the variable called PressedJump in the Jump function is read-only. How can I change that?

[runic terrace]

Why would you want to change that? It would just reset to its original value

[trim matrix]

In the official document, the variable is changed to set the value of "IsJumping" to be used in the state machine. I wonder how they can make it.

[runic terrace]

I'm guessing it's a custom created variable not a built in one

Can you link the document?

[trim matrix]

https://docs.unrealengine.com/4.26/en-US/InteractiveExperiences/HowTo/CharacterMovement/

[runic terrace]

Below the "Creating the Animation Blueprint"

they create custom variables and set it

Create a boolean "is Jumping" variable in the animation blueprint, then set it to the read only "Pressed Jump" variable of the Character blueprint.

Pressed Jump isn't being changed here

[trim matrix]

I wonder the value of isJumping is set by PressedJump. PressedJump is not changed here, but I can't change it either after press the spacebar in the character bp

so the value of isJumping is always false.

[runic terrace]

Is the cast to the character successful?

[trim matrix]

yes. I made all other actions successfully.

[runic terrace]

Okay wait I'll try testing it

Oh yeah, pressed jump doesn't seem to change its value

You can use is falling as an alternative to check if the player jumped and is in air

[trim matrix]

Yes, I tried that. So the official document really makes me confused.

[runic terrace]

Might be an old document and the variable is deprecated

[trim matrix]

Maybe. Thank you after all.

[runic terrace]

You're welcome

[main smelt]

I have a really basic question. So I have a mask and all I want is to make a parameter to invert it. I know I have to use oneminus but don't know how to tie everything together to trigger the switch. How do I do that?

I also want to effect all parameters that are already there

[earnest tangle]

so you want a parameter that chooses when the mask is flipped?

[main smelt]

Yes and all parameters will control the invert so that I believe should be before everything?

[earnest tangle]

if so, plug the non-flipped mask into Lerp, and then the flipped mask into it as well. Set the parameter as the alpha value. That should do it.. also #graphics is better for material Q's

(There's probably some other ways to do it as well)

[main smelt]

Understood, but I want to have a enable/disable option for inversion so it has to be a parameter. How do I do that going from the existing "emissive mask" node? And once the inversion parameter is enabled it takes over the original one.

Will write there next time.

[earnest tangle]

Yeah as said you create a parameter and plug it into the lerp's alpha param. That would allow you to toggle which lerp input is used based on it

[main smelt]

How do I make a parameter since oneminus nor lerp can be one?

[earnest tangle]

the node is called scalar parameter or something like that

or just copypaste one of the existing parameter nodes and rename the parameter to something else :)

[main smelt]

ohh I'm stupid, I didn't see lerp has an alpha value for parameter haha

[earnest tangle]

heh

[modern shuttle]

hi guys. i have a problem with a car. i have 2 event 1 that trigger the brake 1 that trigger handbrake. i want to set a material for the brake. i cant get work by the 2 event. how can get it work ?

Works perfectly thanks a lot!

[earnest tangle]

👍

[main smelt]

Btw instead of scalar parameter is there one that has only 0 and 1 without float?

[earnest tangle]

I don't think so

I think there's a boolean switch thing or something, but afaik it doesn't work with dynamic material instances, so it depends on what you're doing with it I guess

Guys, why isn't 'IsValid' preventing the hit result to be called? I keep getting the error that no result can be accessed on set control rotation

[hushed badge]

my character is always looking forward anyone knows how to fix it?

[orchid garden]

fix it to do what exactly?

[atomic salmon]

@hushed badge check whether "use controller rotation yaw" is active

also check orient rotation to movement inside the character movement component

[tacit oyster]

Hi everyone, I have an actor with a box collision as root component. The actor has a procedural mesh component (it works as a normal static mesh component) that I set at runtime. But when I set the mesh it doensn't fill the collision, the pivot of mesh is not at the perfect center.

[orchid garden]

whats the non-physics based version of this? just set velocity?

[formal cedar]

Hey guys is it possible to make a game pause when no keys are being pressed? I basically want to make a game where it resumes when the player holds down W, and as soon as the player let's go of W, the game pauses until its held down again

[atomic salmon]

@orchid garden there is no non-physics based version of that. You need to move your actor kinematically which means the velocity results from how you move it between 2 adjacent frames.

In the case of a physics simulating actor velocity is a property of the connected physics bodies and the actor will maintain it until either you set is specifically or forces/torques are applied to alter it (Newton's first law)

[tacit oyster]

@formal cedar yes set game pause on on W pressed and set game pause off on event W released. It should work.

[formal cedar]

Thank you Jobim, quick question can I also have the player walk when We is held down and not walk when no key is pressed?

In addition to this pause system

[tacit oyster]

How to you make that character walk?

[formal cedar]

I want to have the character walk for a long time (holds down W) and then the game pauses when we stops walking (let go of W)

Only walking forwards no left right or back

[hushed badge]

its active

but after i turn it off only the character moves left and right not the camera

i checked the other thing nothing changed

[tacit oyster]

Add AddMovementInput node when W is pressed, something like this https://docs.unrealengine.com/4.26/Images/InteractiveExperiences/Input/MoveForward_Blueprint.webp

[formal cedar]

I'll look into it thank you sm Jobim!

[tacit oyster]

You're welcome.

[visual vigil]

How to get angle between two actors in negative and positive depending upon wether it is in left of char or right

[atomic salmon]

@visual vigil take the world transform of the first actor (which we will call the reference actor) and the world rotation of the second actor, then feed them into: https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Math/Transform/InverseTransformRotation/

The result is the rotation of the second actor respect to the first actor

Probably you are interested in just the yaw

As an alternative you can do a FindLookAtRotation from the first actor to the second one

but working with Inverse Transforms looks much more professional 😉

[wet urchin]

Does anyone know how to recreate this in UE4

I dont know how I can make it so I can Search a URL in game

[hallow sentinel]

I think you do have to select character to get access to that component. I dont think it allows you to add it to a base pawn. But yeah, I think my problem is that im over complicating the problem and I need to ignore the "bipedal" verbiage it uses.

[visual vigil]

is it possible for something like timeline in animBp

[maiden wadi]

@visual vigilThere isn't really a point for that. AnimBlueprints run on tick anyhow. Just set the state. And if you want a particular animation, do a montage and blend it in.

hi there, im having this issue where im trying to make a co-op/multiplayer game with a health system, but the issue is, if i apply damage to one character, it's applied to all. does anyone know how to make it so the damage is seperate? (for context, im using a blueprint interface to cast the damage to the player using a box colission)

[spark steppe]

i want to make a drone/quadcopter, what's a good way, in terms of performance, to apply some random position offset/rotation so that it doesn't hover in a static position. is there any better way than running a timeline all the time to apply those values?

[earnest tangle]

Is it just a visual effect or is it going to affect the behavior in some way?

[spark steppe]

well kinda affects behavior, going to work on that it tilts in a reasonable way to get back to its origin position

[tight schooner]

If it's non-gameplay then maybe do the wobble in a vertex shader (material graph), but otherwise...

[lofty scarab]

Would anyone happen to know why this is not changing my movement speed?

[zealous moth]

In the material for your drone, you can assign a world position offset. This can either be a transform or a rotation. Using simple sinusoidal functions using time as a variable you can make them hover as you wish.

[zealous moth]

Use print strings and see if they get called correctly

[spark steppe]

yea but it takes away a lot of control from me, unless i add material parameters to tweak each setting, not sure if it's worth the effort

currently implementing everything onTick, as it's just some vector math + interp nodes

[pulsar arrow]

I recently heard that if you have any kind of cast in your blueprint and not even using it, it will automatically add up to the memory, so it means it could easily get out of control and you would end up casting everything. What about interfaces? Are they the same in this regard?

Can using interfaces instead of casting reduce memory usage?

[dense mantle]

yes as you talk to the object that implements the interface no needs to cast at all and nothing to create it is all there already

[pulsar arrow]

So we can say it is better to replace casts or reference variables with blueprint interfaces

[frigid ether]

The way casting works is that casts need to validate EVERYTHING that the cast is related to, so if you cast to an AI for example, and he's holding a gun, you also need to validate the gun, and UE has to hold everything it's validating in the process in memory at the exact same time.
Interfaces don't do this and really all they do is send a message out, if you're a good programmer, it'll work 100% of the time

Casting is used for prototyping ideas in controlled environments

Interfaces is how you wanna do things in the final product

[wind sequoia]

not exactly

casting and interfaces serve very different purposes

casting is for going down the class tree in a sense

casting is not inherently bad

[torn kettle]

:triangular_flag_on_post: LearningCrypto#7155 received strike 1. As a result, they were muted for 10 minutes.

[pulsar arrow]

Thanks for the answers! Could you guys give some example about when to prefer casting or interface?

[frigid ether]

There was some talk I believe where a UE developer pointed out that casts can crash games on consoles, because they have no virtual ram, and because of the validation process casting has to do, but it was old so it might not be relevant anymore

[wind sequoia]

without having to inherit from one universal class

most of the time though casts are fine if u use them correctly

[frigid ether]

You can also retrieve the object and talk to it like this, so it's very similar to casting, but I've noticed it sometimes can crash the game if the engine is still in the process of setting the variable and you request data from it

[pulsar arrow]

So casting to animbp makes sense because it will be displayed anyway but casting a boss is no way to go, right?

[frigid ether]

I think the casting really just became an issue once you had a VERY large game

since the validation could branch out to hundreds of things

It was somewhere in this talk he mentions casts can crash games on consoles

https://www.youtube.com/watch?v=EM_HYqQdToE&t=5345s&ab_channel=UnrealEngine

[frigid ether]

Casting to a boss might be fine, you just have to think about the validation process of everything connected to the boss, like it's components. Casts only have to do this verification like once in a thousand times, and the validation branch has to be pretty big I believe

[pulsar arrow]

Thanks, I’ll need to review and rework most of my code then. I should look into other common mistakes before I start I guess.

[winter garnet]

Does any of you know if Unreal caches GetDataTableRowNames? The question is because - should I cache the results manually or can I keep reading from DataTables without having to worry with performance?

[spark steppe]

but one can use isChildOf Class to check if something is of a specific type?!

or am i missing something here and it's also doing a lot of validation in the background?

ok, then about the cost of casts (everything has to be loaded...) why would i cast something that isn't loaded?

e.g.: i cast a lot to my specific character class, but the character is loaded anyways, just trying to understand if thats an expensive cast or not

ok, thanks

[frigid ether]

casts aren't that expensive really, the only scenario I can think of is if the cast does the 1 in a thousand validation process and you have like 50 things connected to the thing you're casting to

I haven't found much info on the validation process though

That's why I think it's a 1 in 1000 type of thing in very large projects, like triple A titles

Then it needs to validate everything it's casting to

[worthy frost]

casting is not really expensive

[frigid ether]

The engine, the why I can't figure out

[spark steppe]

the famous if(rand()%1000==1) revalidateEverything();

[worthy frost]

plus micro-optimizing will limit your game dev

[frigid ether]

I've just seen UE devs sometimes talk about it

Yeah casting is not expensive

[worthy frost]

make it work, profile, if its good, leave it.

just remember, if your doing a lot of calcs or array iterating, then C++ is always going to be faster

one thing i highly recommend

a base BP class with no references

but only BP related logic

i have PlayerPawn_Generic_Parent which has no references, no skeletal meshes, etc

then PlayerPawn_Generic which has references

i cast and put logic in the Parent, to avoid reference loading

if i need BP logic (for things that are simple and don't really need to be in C++)

i never cast to PlayerPawn_Generic from any other bp

heard this from someone some time ago, and it really is a solid approach

[spark steppe]

but couldn't all of this be avoided by making your own CastTo Node which does the c++ way of cast!?

just wondering

[worthy frost]

problem with casting is that node needs to load that BP to find what stuff it has

if you have a base bp you can cast to then you can avoid the expensive loading and cross-loading of assets

especially things like particles, textures, mats, skeletal meshes, etc which your player bp likely has

[frigid ether]

This does answer the first part of your question, he used a bit of an extreme example but it seems yes if you have a cast in a blueprint (they were using it though) it loads whatever the cast is referencing
https://youtu.be/2edoacF53F0?t=1742

[pulsar arrow]

Thanks for the video, I’ll definitely watch this asap

[spark steppe]

i'm having an normal actor, is there any way to add the character movement component which the pawn class uses?

[pulsar arrow]

Not sure if I understand correctly.
Do you mean if I have a character BP, I should create a child from it and hold every skeletal mesh, particle or any other thing that is not mandatory in the child and base things in the parent. After that I should cast the parent so I won’t have to load particles static meshes or other things. Is that correct?

[trim matrix]

Why is my PHYSICS VOLUME not changing a thing.

[grave relic]

Im am once again asking for your knowledgeable support. Currently I have a system that tracks what time of day it is, morning, noon etc. I store these as ints, so sunrise is 0, morning 1 etc. I use a event dispatcher to notify all entities that the time has changed. Thing is that currently to tell the entities what time of day it is im casting to the sun controller. And ideally i wouldn't want 100+ entities casting to the controller. 🙂

[spark steppe]

you would add a integer variable as input to your event dispatcher so you can have the timeofday as argument for it

you may have to recreate your event things, as they often don't update when changing the signature of the dispatcher

[grave relic]

But how 😮

[spark steppe]

top inputs field, there should be a small plus

it's not good integrated in the UI for sure 😄

[grave relic]

Goddamit i legit dident see that one, been trying to figure it out for sooo long. Why cant it just be like with interfaces

[spark steppe]

thats the output, not input

however, beside of that you might want to consider to make yourself a custom enumeration with morning/noon/afternoon/etc...

it makes your code/bp more readable and it's as cheap as using a integer

[grave relic]

Yeah but thats in my interface, just wanted to shot it as example 😛

But will fore sure make a enum, currently in early testing ^^

The output vectors are then passed to a shoot routine where the line trace is performed.

[spark steppe]

that's because you seem to trace from the gun, idk if FPS do that, too

guess they trace from the camera

[blazing moth]

yeah, I think I'll need to pass three vectors. Two for the actual trace, and another to get the trace particle beam to match up with the gun

[runic terrace]

I had this happen, it still works without any problems that note is lying lol

[hexed cloak]

Can you set an AIPerception component's sense config in blueprint?

[radiant mural]

Hello everyone. I need some help with something here.

How can i assign a Skeleton at runtime? the equivalent of "assigns a skeleton to the selected mesh" at editor level alt text

How can i do this through BP or C++ during runtime?

Thank you

If you respond to me, please use the @ so i can actually find it 🙂 Thanks

[maiden wadi]

@glossy gladeBy the time Beginplay runs on your Controller, all three will exist. GameMode is required to hold the classes for both GameState and Controller, GameState is the class that actually calls beginplay, so by the time a controller calls Beginplay they will all three exist. On the other hand if you're talking about Beginplay order, you can't promise that at start of play. There are some ways around it, but in general they all involve simply registering the actors somewhere, and when all three are registered to be ready, then call the functions you need.

[maiden wadi]

@trim matrix No. Nothing is by default unless you mark it to. Most things in blueprint are copied.

[true marsh]

What are the repercussions if your function gets too large? Say with too many additional functions inside it

[maiden wadi]

None really. Just takes slightly longer to process with more stuff to do. Of course that depends on control paths. You can compute half of the world on one control path, but if that path never gets used and the other part of the function is just returning 2+2 as an integer, it's going to be pretty quick.

[noble cape]

does anyone know why this isn't working?

I'm trying to stabilise the head bone on my character, I pass in the previous VB head transform as LastHeadTransform and the camera transform as CameraTransform and I have a tolerance on how much the head bone basically lag as the Tolerance.
the tolerance is given in how much the head bone can "lag" relative to the camera, so if the tolerance.x is 0 it means that it shouldn't lag in the x axis at all, relative to the camera.

not sure if it's very clear, I just have a virtual bone called VB head attached to the root->head bones

idk if i got this completely wrong, since it seems to work sometimes but the rotating the old VB head - new VB head with the camera rotation and then inverse rotating it seems to cause issues since the values don't seem right

the one above is wrong, deleted a few nodes by mistake

[full wadi]

Hey i am trying to deform cars and meshes in ue4 can anyone help me, how to do it

[atomic spade]

I'm getting a certain error when trying to pull variables off of a character component into an animation BP. Anybody know what's up with that?

I've done this a zillion times idk what's wrong with it.

[maiden wadi]

BP_DistanceMatcher is invalid on that TwinblastPlayerCharacter.

[atomic spade]

I assure you, it's there. Why wouldn't it be valid?

[atomic spade]

Or rather... What would make it invalid?

[maiden wadi]

That's odd then if it's a class default.

[atomic spade]

So it isn't just me. That actually makes me feel better, not having done something wrong for once 😂

[maiden wadi]

Does it actually work though and you only get that error once?

[atomic spade]

Nope it throws the error and I get A-pose

[orchid garden]

isn't the error he's getting saying the value he's trying to get from it is invalid rather then BP_DistanceMatcher?

[atomic spade]

Doesn't work, error once.

[maiden wadi]

What AnimBP event is this execution line on?

[regal canopy]

Hey guys,

I am working on a game where if the player dies he re-spawns instantly to the nearest checkpoint, but as you can see in the video their are falling platforms. Question is how do I restore them back to their previous locations.

[atomic spade]

I added in an "IsValid" macro to check... yeah not valid.
Which is weird BECAUSE the actual functions that the BP_DistanceMatcher performs still work just fine. So it's like it's not valid to the AnimBP

[trim matrix]

i was following this https://youtu.be/eNkmF7u9V8g?list=LL video but it's not working for me any help?

i can change settings and everthing but it's apply anything

[orchid garden]

i'd suggest you ask on his discord, alot of helpful people there:
https://discord.gg/sY3BZD7E

[trim matrix]

Oh thanks

[atomic spade]

One thing you could do is once they fall a certain distance, teleport the platforms to their original position

[orchid garden]

🙂 np, itsmebro is pretty active in his discord

[trim matrix]

ok 🙂

[regal canopy]

Don't we have some other way

[atomic spade]

I mean there are more complicated ways.

[jovial dirge]

Anyone using advanced steam sessions?

[regal canopy]

Please tell I will take a look

[jovial dirge]

I'm stuck on trying to get the player count in the current session...

Always displays 1/(max players)

[atomic spade]

Use a timeline with a float curve to drop them and slowly bring them back up?
Set the original location of a platform on begin play, then send out a dispatcher to all platforms to reset to their original location when the character dies?
Use the save game functionality?

These are all way more complicated than teleporting them back after a delay

in order of least to most complicated

@maiden wadi Did you abandon me and label my fluke a lost cause? 😂

[regal canopy]

Thanks bro

[orchid garden]

i'd reset them on player respawn rather then player dies, respawn can take a second or two, costing time with your dropping platforms, making them have to rush with less time while respawning.

[trim matrix]

Can you have two different axis bindings on the same axis. Example Mouse X is assigned to two different axis bindings

[orchid garden]

yes

only reason i know ya can is i did it recently in 4.25

[trim matrix]

Oh I love unreal :D, because when I assign to second axis binding The first one stops working any ideas why does it happen? One binding is in blueprint second one in C++

[orchid garden]

o.O intresting, wasn't happening to me (4.25.4)

mines fully bp though

both mine have the same axis scale, donno if that makes a difference

[trim matrix]

I don't think it makes a difference mine have the same axis scale.

[orchid garden]

hrm... intresting indeed, everything was working properly too...

[jovial dirge]

Anyone familiar with steam advanced sessions?

[orchid garden]

i was litterally messing around with the hang glider from UE 4, changed it all to mouse control with the axis values, and was getting readouts for both on the printsstrings.

[maiden wadi]

@atomic spade Hard to say what it is. If it was PIE testing, the cast should fail for the editor preview. For anything else it should work for that class type if it's a default actor component unless you're removing the component somewhere.

[trim matrix]

When I add second binding , the first one doesnt get any axis values. Event is fired properly but axis value is always 0.0 even though second axis binding receives proper values

[atomic spade]

https://tenor.com/view/anomaly-paranormal-anomaly-detected-detected-ghost-gif-17162363

[orchid garden]

yeah was just gonna say try appdata, might default there

[teal root]

Hi guys, does anyone know how ALS keeps the mesh component attached to capsule component during physics simulation in ragdoll mode? Doesn't physics simulation auto detach mesh from its parent component?

[icy dragon]

Because there's no practical reason to do so.

[teal root]

I want to know how ALS did it, meaning keeping mesh component attached to the capsule component during physics simulation. When I enable physics simulation, mesh component auto detach from its parent component. I couldn't figure out how LALS did it.

[mental vale]

Pretty familiar what ya need to know?

[finite dawn]

Hello there. Need a little help here. Is there a way to record in-game camera at runtime? Considering i need this to work even in a packaged build. And later output it in some common video format. Any suggestions are super appreciated.

[cursive path]

I need help with set visibility in widget not working

[trim matrix]

@finite dawn There is a plugin/script in Marketplacec for that. So it's deffinitly possible but you will have to work it out somehow

@cursive path Show your Blueprint

try 2 sided?

[runic plinth]

It's worse, seems like a boiling pot with that option 😄

It's spotlight and not pointlight got it

[coarse flicker]

Would it be more efficient to do a sphere trace on tick or have a sphere collision which rotates on tick which checks for overlap? 🤔

[maiden wadi]

Traces are incredibly cheaper than movement stuff usually.

[coarse flicker]

I see thank you.

[fiery swallow]

You could run like 100 Line traces on tick and be chillin, as long as you use a realistic distance

[coarse flicker]

I saw on a tutorial video people saying sphere traces are not efficient. And that is what I'm using hence I got curious

[maiden wadi]

I.. Don't know what they're comparing sphere traces to then. I mean I have a mid line CPU, and I can run thousands of sphere traces per frame in blueprint with little impact to gamethread.

I dunno. Maybe they're phone developers or something and traces are terrible on phones? It's hard to believe that anyone using a PC would find shape traces expensive.

[atomic salmon]

Spheres are the most efficient collision primitives since checking for overlaps/hits just involves a comparison with their position and radius.

[burnt igloo]

I am watching the unreal tutorial on blueprint essential concepts, and I don't get how it takes like 20 blueprints just to open the door!!!

[gaunt lotus]

Does anybody has good tutorials/guides on making 3rd person raycast/crosshair ?

[brazen pike]

If my distance is like 300 units, it's fine if I have 4 different line traces (one of them on tick) that goes off frequently? Not much of a performance hit?

[paper galleon]

Like ricochet?

Increase the bounciness in your projectile movement component

If you want it to precisely bounce from one enemy to another, you'd need to setup homing and homing targets

[burnt nest]

You could take the OnHit event, then GetAllActorsOfClass, loop through your enemy classes and check which one is closest and if it's close enough for a bounce, and if the projectile has bounces left and then whatever logic to fire the projectile at the new target.

[paper galleon]

There's one by Matthew Palaje on YouTube. Seemed straightforward and worked well.

[burnt nest]

I believe if you activate homing when the projectile hits something initially (if it hit an enemy), and then set the homing target component, it should automatically go to the new target.

ok ive been stuck here for a minute. any advice on how to fix this/resources to learn what im doing wrong? lol basicly my problem is when my player character "dies" in my third person shooter, im still able to move around and shoot while laying on the ground. Thanks in advance

i think this is where the problem is, i copy pasted from my ai blueprint. (the connection to disable input from "get controller" was my last attempt at a fix

[unique wasp]

I managed to get Unreal into a state where the editor crashes on startup after I made a change to a Blueprint (it also crashed when I made the change). Is there some way of handling this kind of problem without recreating that entire Blueprint?

[wraith comet]

If auto saving isn't disabled, you can find older versions of uassets in your project's folder: saved/autosaves/...

[unique wasp]

@wraith comet That's good to know for next time! For now it won't help me because I started by cleaning my project folder, hoping that would fix the problem, thus deleting those backups. A good choice of mine... ;)

For now I'll just recreate the Blueprint, but for next time this will definitely help, thanks!

[burnt citrus]

Hey I have a question
How to use output in Blueprint Interface?
adding any function or event isn't allowed in BPI, then how to output something in BPI?
Please show me example if you could

[smoky ice]

Does anyone know if foreach loops in BP execute once silently even if they are never triggered in game? I'm getting this error:

Blueprint Runtime Error: "Accessed None trying to read property CallFunc_Array_Get_Item". Blueprint:  BP_WSPGetZonesAvailable Function:  Evaluate Immediate Graph:  ForEachLoop Node:  Branch

From a loop that never gets hit, it's as if it's getting a populated array with null entries.
The break point on the foreach is never even hit, but the mere act of wiring up the nodes will trigger the error.

[peak gull]

for the record, anyone who gets stuck in a similar way to me, it worked perfect when i put a disable input on the blueprint string above where i thought the problem was. after the Custom Death BP rather than the Death anim BP i feel dumb XD

[orchid garden]

a blueprint interface is just meant to allow conversation between one blueprint to another, i.e. similar to calling a custom event within a single blueprint. any functions you want do do wout be done in the blueprint receiving the call from the bpi

[earnest tangle]

No, foreach loops only run if there's something to loop. It wouldn't make any sense for them to run with no data

[peak gull]

so happy i fixed this, a few cups of coffee and some deterimination go a long way (getting up before the kids to work in silence helps too :P) ima just lurk now while i continue to work. Level design step is close now

[orchid garden]

if its connected up, even if you never call it its still compiled at runtime, and if there is a error within the routine it will toss errors at you.

[burnt citrus]

Well....
so, BPI's output is trash?

[orchid garden]

?

[burnt citrus]

BPI out put is useless?

[orchid garden]

no

[earnest tangle]

BPI does not output anything

it's more like a declaration of what objects which implement the interface can do

you can for example have an interface which is called "interaction interface" and it has a function called "Interact"

now in your game you have chests and boxes and people, and you can implement the interface on all of them

[orchid garden]

bpi's do output

[earnest tangle]

and you don't need specific code to handle all those different types of interactions

[smoky ice]

Yah that is expected, the issue is it's the foreach macro itself and I can't see anything feeding into it, maybe there is something in a weird state and it's running somewhere weird.

[burnt citrus]

it's input pin in BPI

[earnest tangle]

@smoky ice perhaps, have you tried adding a print node to check the length of the array or such?

[smoky ice]

I've branched with a length > 0 check just to confirm, and it's always correct, I never get [0] = none

[earnest tangle]

@burnt citrus I would recommend checking this one out, it talks about interfaces amongst other things https://www.youtube.com/watch?v=EM_HYqQdToE

It has a table of contents in the description if you want to skip directly to the part with interfaces

[smoky ice]

I've worked around it now so it's not an issue, and generally I write most code in cpp, this just seems odd.

[burnt citrus]

Thanks!

[earnest tangle]

I think the error seems to suggest the value of your array is actually none 🤔 but not 100% sure. it's definitely weird, I've never really had this problem in BP's

[smoky ice]

Yah that's my assumption, although in a BP there's no way to check if it's actually none as far as I can tell, so there might be some weird chain of events coming from C++ where it's actually nullptr or something.

[earnest tangle]

Sounds possible yeah

[peak gull]

@earnest tangle thanks for that live training. honestly if unreal cleaned up their playlists their youtube would be much more helpful imo

[earnest tangle]

Yeah there's a lot of useful stuff in these, but it's a bit of a pain when it's 2 hours to find the bit you need sometimes

[hasty moat]

Hi gals and guys, I've got a question, maybe someone can help me.
I'm adding an evade ability to my character. Let's say I want to dash 1.5m forward. I can calculate the end location easily. For the actual move, first I've tried using Apply Root Motion Move to Force, and it worked fine, I could control the move distance precisely, but I cannot apply any curves here to control speed.
Then I tried using Apply Root Motion Move to Actor Force, but I can't get it to work properly. First it takes Location Offset, so I get the offset by subtracting previously calculated End Location and Actor Location. It moves me in right direction, but way too much. Only when some curve is added for horizontal speed does it look fine, but still I lack precise distance control. Does anybody know how to use this function properly. I'm basically blindly changing params until it looks fine, but things may go haywire with the first change that happens 😄

[hushed pewter]

not quite sure, maybe you'll have to create a widget with image element, and than add that widget as a component to your actor...there may be easier way to do this, do check 🙂

Hi all, hoping somebody can help me with what I assume is a really simple oversight. I'm loading in streaming levels via a combo box for different options of a building. Each saved to it's own sub level. This works fine, but I can't figure out how to unload them when the combo box selection changes to a different level

[fiery swallow]

There's pretty much 0 performance hit. Epic Games ran a test live with 3,600 line traces running on tick and not a single hitch came up.

However, it wasn't until they ran 36,000 line traces on event tick that they started losing milliseconds

Hi, i'm trying to upload a file to a GraphQL server and i'm having trouble uploading the file into the JSON. Can someone help me?

this is the request i send

[runic terrace]

I didn't use Va Rest that much but aren't you supposed to set the fields in the Json Request object and pass that?

[minor pagoda]

yes, but varest does not allow the field type to be file type

only allows objects, string, int and so on

[runic terrace]

I don't think it's possible to upload files directly with VaRest

If it's an image you can try converting it to a byte array and send that instead but that would probably require c++

Not as far as I know, but you can change the skeletal mesh at runtime if that's helpful

[tight schooner]

Well this sucks. Apparently overriden variables in components, i.e. values you've changed in the level editor UI, cannot be read in a construction script (https://forums.unrealengine.com/t/read-component-properties-in-construction-script/132760/5). This throws a massive wrench into my component ideas if the host BP class has to house all possible variables that components would use in construction.

Any way around this?

[astral cedar]

how could i get a characters forward axis that's aligned to the slope its on

[tight schooner]

yeah, but I need it in construction for level editor/workflow purposes. Guess I have to stuff a bunch of public variables into the host class

[icy dragon]

Why not consolidate your construction script nodes into a macro, then put it in both construction script and begin play?

[earnest tangle]

^this is in general a decent method altho I use functions usually

sometimes I need to apply the same changes the construction script would do for example on game load, so it's easy to just call the function to do that logic when the values have loaded

[open crypt]

nav mesh makes no cost/calculations for empty space right? I just wouldn't want it on a big level because I'd pay for the calculations wherever the nav mesh bounds intersects geometry flagged for navigation, correct?

Imagine if you had a huge nav mesh bounds but streamed in levels after different heights, like floating islands - there wouldn't be a cost associated with having a huge one in the spaces that the unstreamed islands weren't loaded, because it's empty and has nothing to calculate

[fierce birch]

hello all having issue with enemy reference that is being set by line trace. im aware that i need to add a is valid but i didnt to explain the issue. what im making is a life steal ability that only works if you get up close to an enemy. it works sometimes and doesnt on others. confused on why it doesnt because the line trace is clearly hitting the enemy

[open crypt]

You need an IsValid because some of those crab actors are in the process of being deleted - so if you are shooting them for example, you are activating whatever function destroys their actor and spawns in maybe a mesh ragdoll to be the dead body - but before they are destroyed, they are still hit by the linetrace

It's a part of what is known as "garbage collection" because the code is executed so fast, some parts of the actor exist and other parts don't - it's not important to understand what exactly, just put an IsValid after your True branch (the second one)

@fierce birch

[fierce birch]

ok

[open crypt]

You "might" need to do anything one on the reference set at the end too

I don't know enough about garbage collection to be sure, but if you get the same error again, try adding it there too and seeing if it goes away

[fierce birch]

i did check for the is valid

it works fine until a enemy dies

then the ref wont update im assuming

[open crypt]

correct

because by the time the line trace ended, that enemy was gone

rather, destroyed

[fierce birch]

but i thought that the enemy ref will update when i hit another enemy

because its on tick that the trace is getting exec

[open crypt]

yes but there is still an instance where the assignment of the variable is being attempting to be placed as a reference to an actor that is in the process of being destroyed

[fierce birch]

hmm

[open crypt]

I'm not certain but I believe that error is a safety check built into the engine to avoid crazy crashes - the moment something is flagged for deletion/destroyed, the actor keeps that flag, that way if any code attempts to interact with it, the engine fires a warning - think of how hard it would be to debug problems if you didn't have that code because you were destroying an actor

[fierce birch]

how would i fix it?

[open crypt]

But an IsValid anytime you reference that actor

soryr, PUT

[fierce birch]

i am but its not working

it just wont let the ability work

[open crypt]

so you need to probably find where you are destroying them and examine the timing of it - maybe put a slight delay in it

for example, you could set a boolean on it that sets as TRUE once whatever code you want to run on it when it is hit/destroyed, and then check that variable to be true, before you call the destroy actor event

[tight schooner]

I'm not sure if I follow. The fundamental issue I'm facing is values in components that I've overridden in the editor seemingly cannot be read by the editor (i.e. before beginplay)... When I Get those values, it gives me the variable's default rather than the value I entered. Is there a way to actually get those values? Or must I fundamentally put those values into the BP actor class to use them in construction?

[open crypt]

did you put them as "Expose on spawn" as well?

[tight schooner]

I tried... doesn't work

[open crypt]

you need to set them again at begin play

can you show me some of the code? like one of your instances?

[tight schooner]

Maybe we're talking about different things. I'm talking about public variables on BP components not being accessible in a construction script. E.g. I changed the variable "Rail bar length" to 3 but when I try to read it during construction, it shows 8 (the default).

Because components don't even have construction scripts, I use the host actor BP's construction script to call an event on the component. For debug purposes, the event appends some stuff into a string variable called Debug_pseudoprint as shown in the screenshot.

My actual use case for doing this is to show some level design visual aids in the editor based on the values entered

I wonder if editor-only BP functions have the same limitations...

[fierce birch]

@open crypt but I have multiple spells. How would you suggest I work around that

Nvm I’m going to try something out

[open crypt]

Consider having an interface

that triggers the same TYPE of event (like an interface function "HIT WITH SPELL" but is implemented (does different things) differently on the different actors

so "HIT with FIRESPELL Event" executed on Plant triggers 200 damage and plays burning animation - but that same event executed on STONE does 10 damage and plays smaller fire animation

[fierce birch]

I’m using an any damage so would a interface be necessary I’m going to add a Boolean and try a few things out

[trim matrix]

would it be a bad idea to put custom events onto a tick node for cleaner bp's?

[open crypt]

depends on the events really, but you could always do them on a delay

tick is not the death sentence it is made out to be, you just have to recognize it's more about using events to drive things versus always checking their states

I have a vehicle system that uses tick to drive the entire status of a car and it runs fine but there is a slight delay in the tick

[trim matrix]

Yea I just got a bunch of stuff that needs to go on tick tho, Maybe I could use loops but idk

but I dont wanna attach everything to the tick node

so I made a custom event called linetrace and just hooked it up to the tick node, another one called stamina/health regen. etc etc

now that I think about it I could just use one custom event lol

[open crypt]

you can do event by timer too

[trim matrix]

hm let me look up how that works haha

[open crypt]

just run the event by timer, and plug it in to the actual event you want to run, and set the blue one to looping (basically do it at begin play but have a boolean before it so you can stop it )

[trim matrix]

so its a tick event you can stop basicly?

[open crypt]

maybe, others would know more - you can semi-stop a tick by just putting a branch after the tick itself -

technically that actor is still ticking but it's just a single node that's ticking

[trim matrix]

yea ticks are still pretty foreign to me

I just know theyr bad..ish

[open crypt]

No, they aren't

they are like paying someone a 24 hour wage when you need a wakeup call once a day

[trim matrix]

yea theyr just not optimal at all

but idk how much resources they take up by just.. attaching a healthregen system to it

[open crypt]

they can be absolutely harmless and I use them frequently when I am prototyping or just one something done fast

[trim matrix]

probably nihill

[open crypt]

you can profile it in the engine, just look up cpu profiling for unreal blueprint
