[fierce birch]

@orchid star it worked for respawning only 3 times then it stopped

[orchid star]

where do you respawn

[fierce birch]

in the spawner

[orchid star]

you bind it on inital spawn

after getting killed

you only call the spawn function

you are not binding it again

bruh

[fierce birch]

ok would this work?

[orchid star]

try it out

it should

[fierce birch]

works sometimes as well

@orchid star is it because i set actor lifespawn in the acotor?

[orchid star]

cant say much

[fierce birch]

what would you suggest?

this is the error message

[orchid star]

maybe being destroyed before binding

whats in your spawn enemy code

[fierce birch]

i changed set actor life span to destroy actor and it worked more

is it a garbage collection problem?

[zealous moth]

No it is because you destroyed it while it is still in use elsewhere

[fierce birch]

@zealous moth when the health is 0 the event dispatcher is called before it destroyed

Hey all, I'm using proximity voice chat in my game using VOIP, I followed this tutorial... the only issue is- everyones mic is going to the capsule collision, where the (attenuation is) so you can hear anyone if you're near 1 player

https://www.youtube.com/watch?v=cndbrTOAQD4

I am setting the atten settings to the capsule component of the player BP

[somber quail]

hey i really need someones help im trying to look though a array for 2 items but i can only find 1

well i think i found the problem but i dont know how to fix it

its not going through the array

its just looking at the first slot in the array

the array is a group of slots in the players inventory and item in the inventory will go into that array

any of you guys know how to fix that

[astral stirrup]

id use a for each loop

if you connect your array to it it should go through all the entries

[somber quail]

i am

i use for each loop

is there something obvious that I'm just not seeing

[astral stirrup]

i think its the return although im not sure

[somber quail]

no i have tried many different ways

they all have the same result

have it not in a function have it in where its getting the array have it in the crafting system have it in the player

[astral stirrup]

for me something like this works

[somber quail]

strange

[astral stirrup]

try to include functionality in the body

[somber quail]

im not using a instance or anything like that im just using a array that is object reference

[astral stirrup]

i might be wrong since im still quite green with ue, but using a return within a loop breaks it in other coding languages

thats why it might be happening, does one, breaks

[somber quail]

ill move it back to the event graph

there is no errors tho

[astral stirrup]

instead of returning the value try setting a variable

yea its not really an error

could be intended behavior 🙂

[somber quail]

wtf

wtf

no

how

i tried this

EXACT SAME THING BEFOR

WHY IS IT WORKING NOW

[astral stirrup]

1am 😄

[somber quail]

AAAAAAAAAAAAAAAAAAAAAAA

now i need to add the second item tho

[astral stirrup]

glad i managed to crack something 😄

[somber quail]

i hate this

i did the exact same thing befor

now it works

now watch it break when i add the second item

[astral stirrup]

probably some node unconnected or something stupid i do it all the time

[somber quail]

yeah nah not working anymore

once i added the second item

how would i add the second item tho

just add another =

or do another for each loop

[astral stirrup]

you have an array with a list of items, where are u adding it to, like a ui?

[somber quail]

kinda it is checking through the array and if the player has 2 items it will make a button visible

[zealous moth]

Look up my message from today i did a count function

[astral stirrup]

they have different classes yea?

[zealous moth]

Uaes a map output

Uses*

[astral stirrup]

if u need to check for a different class u can use the OR bool

[somber quail]

i need a and

its needs both items

i used a and but then it breaks it

[astral stirrup]

yea coz its a for each loop

[somber quail]

i think its trying to find both items on the same slot

[astral stirrup]

it will already go through all

so it will never reach a case where both are true

coz its looking at em one at a time

[somber quail]

oh

then how would i do this

[astral stirrup]

or bool

[astral stirrup]

then u could create an int

that would keep track of the item count

and increment it by 1 on true

and from completed in the for each loop u could do another check if that int is equal or greater than 2

if so show button

and u can run that loop every time u pick up an item

so it only checks when its actually needed

[somber quail]

ill do what you said befor see if that works if it dosnt ill use the int idea

im using boolian so when it finds the correct item it will just make the boolian true

then it will try and find the other item when it does it will make another boolian true

then ill just use a and and put the 2 together

[astral stirrup]

yeah that should work too if u never plan to have more items needed

at once

[somber quail]

it worked

thanks man

[astral stirrup]

happy days 🙂

[somber quail]

its a bad way of doing it there is another way of doing this but for now

this is the way

[astral stirrup]

maybe looks messy but booleans and math are actually quite fast

[somber quail]

ooohhhh thank god now i gotta get the craft button working and to minus the items in the player inventory

hmm

tru

the items needed are glow slime and normal slime to make a slime potion and if you eat the glow slime it makes you glow

[astral stirrup]

thats cool, you will prob have more of those at some stage

[somber quail]

wdym

[astral stirrup]

diff recipes

[somber quail]

ohh

yeah

if you mix glow slime and normal slime i want it to make a slime potion that turns the player into a slime making them immune to any slime attacks

slime

[astral stirrup]

trying to think of a good way of implementing this

so that when u want to add a new one its quick and easy

[somber quail]

yeah

ill think of something later when its 3 oclock and im just lying in my bed

[astral stirrup]

heh yeah its a bit late for this

wanted to ask my question but its a ghost town 😄

can always try i guess, im trying to create thumbnails dynamically using the 2d capture component, i think i figured out how to save them correctly but no clue how to access them from elsewhere

this is my saving bit

[somber quail]

wt wait im not that advanced yet are you able to dumb it down a bit

so

your trying to make a image and save it?

[astral stirrup]

yeah im hoping maybe someone good with ui will see it 🙂 yes there is a component in ue4 that allows to project a camera on a 2d surface, can use it for many things but i want to save the results in engine as material instances and use them later for thumbnails, cant seem to find a way to reference them

[somber quail]

i would just use the scene capture

then tell it where you put the image

then make the image a material

bam

no fancy code needed

".uasset' has been saved with empty engine version. The asset will be loaded but may be incompatible."

after upgrade from 4.26 to 4.27, there are many these warnings for the uasset. should i re-open/save all uaaset after upgrade the UE? if it was, is there automatic way to do this?

[sand shore]

Not at all familiar with that video, so I have no idea if this will be applicable.

Does the video suggest using the nodes GetPlayerCharacter(0) or GetPlayerController(0) ? If so, head on over to #multiplayer, and study up a bit on the Game Framework. I wouldn't recommend using those two functions at any point in multiplayer unless you know what ULocalPlayer does

it's one of the most common noob traps, and there's no reason to tutorialize its usage.

[daring musk]

Hi guys, i'm currently working on learning a bit of blueprints for gameplay, and want to know if you know a way to make a trigger box, to check if the asset is cuttable, and with the press of a key trigger the transformation in an asset (i want to be able to cut grass that's the idea).

I tried making a Bool variable, named iscutable?, and get it from the level map blueprint and get that variable into the character blueprint, from that I used the press of a key to check if the variable iscutable? is true and do the transformation but for now it doesn't work

[sand shore]

Not everything is connected

[daring musk]

Aaa little mistake, I connected it but still doesn’t work

Thanks for responding 😄

Here is how it looks now

[astral stirrup]

u are casting ur character to the trigger box

[daring musk]

Yes, i searched how to get a variable from another blueprint in google, and that's the way google showed me haha

[astral stirrup]

the way casting works is u give it a class, when its a match it succeeds, if not it fails and u have no logic for the fail

if u want to get the triggerbox use get actor of class

and cast that

[daring musk]

Ok, i'll try that, thaaanks ❤️

[astral stirrup]

np hopefully it does the job

[somber quail]

nneewww probblleemm

it checks for the item it finds it

but as soon as i added that if it cant find the item it turns off the boolian it broke

now it never turns on

[astral stirrup]

breaks work sort of like returns

if u break the loop it no longer works

[somber quail]

here is the story i thought that it finds the item

makes the bool true

but then it goes to the next one

finds the wrong item

turns off the bool

[astral stirrup]

yea dont break it when it doesnt find

only if it does i think

although i still think that for each loop was a better idea

[somber quail]

can you pls dm me what ever you think or something i have to go and i might not see this

thank you

[daring musk]

Thanks for the help, solved it with your help, but i needed to keep a constant check on the overlap of the trigger so i used the event tick node!

[sand shore]

only break if you're done searching

Then use the completed pin to do other things

[somber quail]

oohhhhhh ok

im back to so poggers

[red grail]

Hello, I need some advice on a more efficient way to expand this interact functionality. I have 8 statues with unique tags and I need to have unique images pop up when I interact with them. I could expand this by adding "Forth Artist", "Fifth Artist"... and so on, but that seems like a bad way to do it if I have a ton of individual statues. Any other way to somehow create a loop or something like that? If you need more images of the blueprint let me know. Help/advice would be really appreciated!

[void comet]

Hey mates. I am setting up projectiles in my project and am having trouble getting overlaps working. Have the projectile blueprint with a sphere collision set as parent with On Component Begin Overlap that checks tag and destroys projectile. Works for actors I have made with the tag but I have no idea why it wont work on my player character. Nothing I try has the sphere collision trigger when it overlaps player. The player has the usual capsule component and I have tried adding a new capsule with no luck. Tried custom collision and every other option. Should be simple, projectile sphere overlaps Pawn and player capsule overlaps WorldDynamic and have tried using hit events also to no avail. And yes, Generate Overlap Events are ticked for both. Any ideas?

[maiden wadi]

@red grail If I'm understanding correctly, that looks like something you would use a Datatable for. Create a single actor that is a mesh, and has the ability to add that widget to the screen, make an instance editable variable of a Name type. Create a datatable with the mesh, materials applied to the mesh, image, and text lines you need like the CreatureName, ArtistName, Description, SecondDescription, etc. Then all you need to do is line trace and interact with one object type, call the function on it and it can show you what you want. Then in your level all you need to do is drop one of those actors in, write the correct lookup name from the datatable in the dropped actor's instance editable Name variable.

[red grail]

That definitely sounds like the right way to do it. Might be out of my capabilities tho 😅

I'll save this somewhere and do some more research. Thanks a lot for the detailed write up! @maiden wadi 😁

[maiden wadi]

It's a fairly easy method. But I know how new things can be to connect the dots sometimes. 😄 Just a sec and I can give you a quick example.

[maiden wadi]

@red grail This might help. Start by making a struct, then a Datatable.

Then make an actor. In the Construction script, set up it's world visual from the table. Here I just did mesh and materials.

Same actor in the Event Graph. I cheated and did OnClick. You would likely make a CustomEvent and call it from your line trace.

Then your Widget is easy after that if you pass in an instance editable exposeonspawn value.

Then all you need to do is drop an instance of the actor in the level, find the ArtName value you're using to look up in the Datatable on the actor's details. Like here I have the cube version selected, it says CubeArt. If you look back at the Datatable, that was the lookup name I gave that entry.

[red grail]

@maiden wadi I think I get the overall idea behind it. That's really fancy! I'll have to spend some time with this over the next couple of days. Thanks a lot for all the effort that you put into showing me an example! I genuinely appreciate it 😁

[maiden wadi]

Tag me here if you have any questions on it.

[red grail]

Alright, will do!

[maiden wadi]

wat?

@valid gyroLike, you want to just spawn one of each node you can have in a blueprint, or?

That would be a lot of functions. 😄

I doubt it though. That's mostly what the right click menu is for.

[surreal kite]

i want to make a camera for a 3rd person shooter game does anyone have idea how to do it or any tutorial ?

[pale orbit]

what is the best way to make a vehicle getting hit by another one get impulsed?

using Chaos Vehicle plugin

[glacial eagle]

Should already do that as part of the physics sim

[pale orbit]

how do i modify the values for it tho

[onyx token]

anyone know how i can snap this cube to the left hand too?

like i read somewhere apparently you gotta use the IK node? But that doesn't make alot of sense, that sounds more like you want to snap the hand to the cube, not rotate the cube to look at the hand

i wanna rotate the cube tho

[surreal peak]

Usually your animation holds the cube already correct and you indeed snap the other hand

[onyx token]

but then i gotta fiddle around with hand rotations and stuff

[surreal peak]

You can add a socket to the hand bone and rotate it

And then attach the cube to that

[onyx token]

like rotate it on every frame of the animation?

[surreal peak]

Will pierce the hand though

[onyx token]

there must be a simpler solution..

[surreal peak]

No the socket holds a rotation

[glacial eagle]

Just change the relative masses of the objects usually

[onyx token]

yea, and the animation points the socket, and thus the cube, in weird directions

Now i can either go into every single frame and hand-fix the rotation

or i'm thinking, just make a lookat thingy for the cube

[surreal peak]

Again usually you have fitting animations

[onyx token]

ok what if i don't?

[surreal peak]

Code something dynamic?

Try to use control rig?

[onyx token]

what does "something dynamic" mean?

maybe a lookat rotation?

[surreal peak]

Idk. The normal idle and run animations aren't made to hold a tick in both hands. Make a pose of the hands being stretched out and blend them into the normal locomotion

Yeah or that. Update the bones of the arms with IK to be on the stick. The stick would need to be attached to something else then though

[onyx token]

well i just quickly copied the paragon animations because i wanna test around an combat system idea i had
https://cdn.discordapp.com/attachments/847253861403197471/879671592626573343/NSzFY4j9BC.mp4

and it annoys me that it doesn't fit right

so i'm thinking - can't i just scuff together a lookat thingy

but lookat didn't work, it just rotated the cube weirdly

and i don't wanna go in, export the animations, import them into blender, fix all the fbx import shit, add a rig, fix them, export them, apply them to the character-

Just to in the end find out that my combat system idea was dumb from the getgo

[surreal peak]

Hm

[onyx token]

like it can weird in the normal idle and run animations, don't care.

I just need to know how i can point a cube from 1 socket to another

[surreal peak]

Maybe this is more suited for #animation then

[onyx token]

rly? Pointing an object from 1 socket to another socket? Alright... i'll go to #animation

[onyx token]

what do you mean?

[turbid thicket]

Hey everyone! I want to save and load presets for my editor utility widget. I need a way to name / save / load and delete presets in my widget. I tried using savegames but I failed. In the unreal forum someone recommended using Primary Data Assets but I dont get how these could help me. I guess its possible to save and load variables but I dont get how to create and name new presets.

I'd like to know if what I am trying to do is possible at all. If I cant make it work its also an option to hire a developer.

(I'm an artist with basic blueprint knowledge but this is nothing I can just do following a tutorial)

[gentle urchin]

When the socket is added it follows the relative location to its root bone. Then the socket can have relative offset and rotation to that .. in case it was unclear... maybe this cleared it up a tad

[onyx token]

no sure, i get that i can rotate the socket

question is how do i make it look at another socket

[gentle urchin]

Usually one offset/rotation fits the entire animation

[onyx token]

or alternatively - if i can't rotate the socket, can i rotate the cube that's attached to it

[pale orbit]

does anyone have any idea why this is not working (game state btw)

[gentle urchin]

the cube can have yet another rotation based on this I think, altho it sounds like fixing the animation would be the proper way to do it

@pale orbit Usually spawning is handled in GameMode .. can't say why yours is not working... is it being called properly? does it have an input? Debug print string to the default output could be helpfull etc

[pale orbit]

its being called froom a widget @gentle urchin

[gentle urchin]

widget cant talk to server, so you gotta go via the controller I believe

[pale orbit]

That makes a lot of sense

thank you @gentle urchin

[maiden wadi]

It's not going through the Widget, it's being RPCed through GameState.

You should put some prints in. See if it's actually running on the server, and see what integer is going through.

Oh

I'm dumb.

[gentle urchin]

Didnt think widget could call the RPC directly regardless but i'm not super versed with it

[maiden wadi]

The RPC would work, except that it's GameState.

GameState is owned by server. Client Can't RPC through it no matter what calls it.

[gentle urchin]

^ This

Ownership.

[tight schooner]

Fwiw I'll say that I use savegame files in an editor utility widget, although I only try to read them and not write to them in the editor. Is it the saving part that you can't get working?

Data assets are like a non-actor blueprint that can't be modified at runtime; they only hold fixed data and functions, iirc. (https://youtu.be/hcwo5m8E_1o) It would be a logical approach to housing "presets" though I never tried creating BP classes within a utility widget before so idk if that's possible offhand. But data assets would be simple enough to make in the editor itself apart from the utility widget. And then once you make them, your widget can read the assets.

guys i want to make a 3rd person shooter mouse movement does anyone knows how or have a tutorial please ?

[surreal kite]

pls somebody answer this

[pale orbit]

Im assuming target is returning that error right?

[mortal breach]

yes

[pale orbit]

Show where you are calling the widget creation from

[pale orbit]

ThirdPersonCharacter on Unreal

[mortal breach]

stream url1 in actor

[surreal kite]

im doing a blank project and the unreal third person project is suck ngl

[pale orbit]

Are you telling the widget who is Target? Its why its returning none

Widget doesnt have a clue whos target since it has no references to it

[mortal breach]

ok

[surreal kite]

@pale orbit can u read ?

[mortal breach]

@pale orbit thanks look at that

[surreal kite]

why my character look like that ? the camera on the right hand why ?

[onyx token]

because you rotated the camera 90°

[surreal kite]

@onyx token GG

XD

@onyx token u here ?

[onyx token]

i don't wanna pm

@surreal kite repeatedly asking for help is against the #rules and will sooner or later result in strikes. Please be more patient. If no one answers you then no one has time or knows the answer.

No idea what you mean. Just follow the rules. Cheers

[wild moth]

Hello 🙂
Does an AND statement abort if it hits a false statement?

[surreal peak]

In Blueprints: No

[wild moth]

T_T

[surreal peak]

In C++: Yes

[wild moth]

Thanks

[atomic salmon]

Shame on the BP Virtual Machine. 😉

@surreal kite you can learn a lot just by looking into the Third Person Template project. If you open the ThirdPersonCharacter BP you will note that the skeletal mesh for the mannequin is rotated by 270 degrees respect to the capsule. That is because the mannequin skeletal mesh normally faces the Y direction while you need it to face the X direction. Check that it isn't the same for your character.

[astral stirrup]

good afternoon, im trying to make dynamic thumbnails to use in a UI, im using a scenecapturecomponent2d and would like to make dynamic materials with the captures, one for each composite mesh stored in an array, currently have a for each loop running from EventBeginPlay, experimenting with RenderTargetCreateStaticTexture node but the textures come out black even though the component works if i just project it as is.

[loud cipher]

hey all

my linetrace is always blocked by the capsule component

hnowever it seems to fix when i uncheck world static

What can i do to fix this?

[olive sedge]

Can I switch out the pawn camera for a different one? (I got a cine camera and I want to play with it in the intro level instead of the normal one)

[raw orbit]

is it possible to enable tick on client but not on the server?

[dawn gazelle]

Yes

[surreal peak]

You mean you are trying to make UI Icons from Meshes, right?

[astral stirrup]

@surreal peak yes, i think i got one step further, capture worked finally, i found the CaptureScene node 🙂

[surreal peak]

So, this is a bit older, but maybe it helps you figuring stuff out (or you just use it): https://github.com/CelPlays/UnrealThumbnailGenerator

[astral stirrup]

@surreal peakcheers checking out now

[frosty crane]

Is there a way I can write documentation for conventions I've established say in the construction script node editor of a blueprint? Multiline comment blocks seem buggy. What do people do for documentation?

[surreal peak]

Usually outside the Engine

On whatever service you use to handle your projects and documentation

[feral ice]

how to copy all the componenets without making one parent and the other children? I am just pressing "Ctrl+C and "Ctrl+V"

[surreal peak]

Eh.

Wait, are you placing grass as single components of an actor?

[feral ice]

yes

[surreal peak]

Pretty sure you should use the Foliage system for that

[feral ice]

what is that?

no i dont want to use landscape stuff

i am going to give this platform a random location and i cant use landscape for that cuz landscpes re static of what i knoe

but do you have answer to my question

[surreal peak]

No I don't

This will give you horrible performance

At least use an InstancedStaticMeshComponent

[feral ice]

the blue one?

why will this give a horrible performance?

[surreal peak]

Because each of those Components is a draw call

While ISMC makes it only one

That's also why one uses foliage for this in the first place, if possible

[feral ice]

but i cant see my mesh in ismc

[surreal peak]

You can add instances in the settings on the right too

[simple imp]

Does UE4 blueprint have an easy way to remove all non alphanumeric characters from a string?

[surreal peak]

Make sure the AnimMontage has a Slot Setup

And the AnimBlueprint is using that Slot

[jaunty field]

there is a slot

[surreal peak]

And the AnimMontage is using that slot?

[jaunty field]

yeah

Nevermind, I managed to fix it!

[frosty crane]

Is there a way in a blueprint at begin play to get all blueprint assets extending a base blueprint class in order to instantiate them dynamically? Trying to use asset registry with no luck.

Basically what I'm trying to do is create extensions of a blueprint, assign gameplay tags to them to categorize them, then using colliders with those same tags, implement some procedural spawning.

I learned how to create custom blueprint nodes in C++ so I'm wondering if there's a way to do it in C++ if there's no blueprint api capable of doing it.

[tired cypress]

I don't know if there's a method for this. But wouldn't you run into the issue that nearly all of the base BPs are extended in some way? I would think you would want to create, say, an array of your classes that apply.

[frosty crane]

Yeah true .. hmm. I guess that's the purpose of an "object library" however I cannot seem to reference this inside of blueprints either. I guess a static array somewhere that I can pull into any blueprint event graph would work.

[loud cipher]

anyone know how i can change the physical material for individual bones on the mesh

instead of the whole character?

[tired cypress]

I don't know skeletals very well but you may have to cast that mesh to the skeletal mesh object so you can access its individual bones

[loud cipher]

okay ill try that ty

[clever cedar]

I'm trying to create an asset in editor. There is a node for it, but I can't figure out how to create the factory input. Can this be done?

[dawn gazelle]

In case you can't find it, the "Create Object" node the person is using in the screenshot above is part of the Low Entry Extended Standard Library plugin.

[proven shadow]

Hi hi, how can I get an event for if a certain button is pressed?

As a type of trigger

Currently I only have an event for if the dialogue is clicked on, but I also want to have one for if a key is pressed

No key press events seem to show when I type in keyboard

For some reason it doesn't show up in the dialogue BP, while it does in the character BP

[surreal peak]

I think only Actors can have Inputs in Blueprints? Maybe Components. The dialogue is a uobject i guess

[proven shadow]

I think only Actors can have Inputs in Blueprints
Isn't it strange that [Is mouse button down] is usable?

[spark steppe]

unreal does auto instancing for quite some time (that was regarding to the ISM recommendation for the guy with the grass as static meshs...)

[feral ice]

Whats the best way of getting the rotation of a point? If I shoot a line trace down in the ground and want to get the rotation of that point how do I do that?

[spark steppe]

you'll probably have to override the onKeyPressed event (if it's an widget)

@feral ice the impact normal is all you can get

which is the "angle" of the surface/collider at which the line trace hit it

[feral ice]

Impact normal is a rotation?

[spark steppe]

it's an vector which you could convert to a rotation

[feral ice]

How did they do that?

[bronze quiver]

are there any good resources for transitioning from C# coding in Unity to swaping to visual like unreal?

[heady terrace]

Hey I have a question. If I make any modifications to an Actor object in the level editor or the Actor's Viewport, does the engine regenerate it? Because I have a Character whose Constructor keeps running and reinstancing some classes. I think it is causing a memory leak.

[spark steppe]

yea every change in the leveleditor/viewport runs the construction script again

[heady terrace]

@spark steppe That means I should add those classes to something like the Game Mode Blueprint instead, huh? That doesn't regenerate does it?

[spark steppe]

i assumed construction script because we are in #blueprint :p

[heady terrace]

So in BP is it "OnConstruction?" Or is the OnConstruction function a feature of UCLASS?

So evenvthough it is a construction script it is still not a constructor.

Because defaults are provided in the blueprint and not visible in c++, right?

No I'm c++ and blueprints. Some things are in bp.

Many are moved to c++ classes and a funxtion library.

[spark steppe]

huh? defaults defined in the class aren't available in the c++ constructor?

then what does the constructor do when nothing is available? 😄

idk if we are talking about the same thing....

class UFoobar extends UActor {
float huh = 10;

  UFoobar(){
    printf("%d", huh);
  }
}

that wouldn't be 10?

yea sorry, i did mostly java the last years 😄

[heady terrace]

Got it! You meant defaults in the bp subclass won't be read in the C++ Constructor.

[spark steppe]

good to know, i would have banged my head when running into this

[heady terrace]

That makes sense considering BP stuff can't be read in C++. Even BP classes and variables aren't understood by C++ code. You'd have to reimplement them in C++ first.

[spark steppe]

but wait

[heady terrace]

"leave some blanks?"

[spark steppe]

if my subclass makes it 20, it's still 20 in the constructor of my subclass, isn't it?

[heady terrace]

You mean leave variables that can be filled in Blueprints after the constructors are finished?

[spark steppe]

what the frick

[heady terrace]

The Constructor runs first, C++ runs before blueprints do. [edit]Right?[/edit]

[spark steppe]

oh wait, it'll probably throw an error anyways if i define the same variable in the subclass

[regal crag]

Anyone got this crash message before?-
"Assertion failed: SceneContext.CustomDepth && SceneContext.CustomStencilSRV [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Renderer/Private/PostProcess/SceneRenderTargets.cpp] [Line: 2350]"

you mean custom depth and custom stencil?

ok thank you

ill check those out

[heady terrace]

I'll move the instancing of those classes into a GameMode blueprint instead. It won't try to rebuild itself if I modify the level or any actors, will it?

[spark steppe]

i wonder what you are doing if you consider to move it to something which should be unrelated

maybe the beginPlay event is an option for you, as it only runs once you start the game/level

[heady terrace]

Well I'm creating instances of state machine classes in the Character.

And every time I modify a spline in the Character, the Construction function runs and those classes are reinstantiated. I don't know if that's a memory leak, but I know UE5 has been crashing.

It's not real development, I'm just experimenting.

It's something for a demo reel.

And that's why I'm here.

[spark steppe]

which seems to like to keep a lot of things 😄

[heady terrace]

Trust me, I don't store variables or objects globally. You don't consider storing objects in the "Game Mode" object to be the same as "storing globally" do you?

[spark steppe]

yes

[heady terrace]

Then maybe I should move the construction of these state classes to the BeginPlay event after all?

[spark steppe]

do you store references to them on the character?

because you could check them while running the construction script

and even just stupidly wipe them when the construction script runs

i guess that would pretty much avoid your "memory leak"

[heady terrace]

Right now they're all stored in a C++ child of the character class. The ThirdPersonCharacter is a child of that class.

[spark steppe]

just make an array<MyStateThingyClass> on your character and store references of them in there

[heady terrace]

The abstract class for the state machine is C++. The child classes are Blueprints. This allows me to prototype game logic in blueprints and I can move frequently used game logic into libraries or the ACharacter child class.

[spark steppe]

then in the first step of the construction script run over the array and destroy everything in there

[heady terrace]

I have.

I am unsure if I want to make them global. There might be a simpler solution, but I'd love to hear about subsystems.

(or do you just want me to google them? >.>)

I wanted to use them both to learn them both while I build the controls for a platforming system. Like in Zelda or Uncharted.

[spark steppe]

the problem is that he seems to create objects, that aren't wiped, and he keeps creating them everytime the construction script runs

[heady terrace]

I do not know if they are wiped or not.

[spark steppe]

that sounds like a homebrew memory leak

if you don't wipe them, they won't be wiped

[heady terrace]

That sounds like what's happening.

[runic plinth]

Hope im not stopping any topic. I'm trying to make something fall by 300 units with a timeline but the actor just zaps through the ground. Can someone tell me what's wrong?

[arctic moat]

is anyone here able to private message? I have questions about how to implement spawn protection into my game

[dreamy river]

Why my event is not firing up? I call it from another widget and I checked with print that its calling it.
Dispatcher is also created correctly, just nothing happens after event is called.

[runic plinth]

Thanks solved. But I don't understand why you need to do it

[heady terrace]

(I'll try solving my problem with @spark steppe 's BeginPlay idea. If that works, I'll get back to you).

[runic plinth]

But the actor is already "living" in a set vector in the map, so in my mind why would you need to "reconfirm" its vector

aaaahh

this

[heady terrace]

A and B have to remain the same for lerp to work properly.

[runic plinth]

Now makes sense, It's kinda of a pain to making lots of variables, but oh well it is what it is. Thanks for the explanation 🙂

[heady terrace]

Ok now that the code is in BeginPlay, everything works a lot better. Thanks @trim matrix, thanks @spark steppe

The big thing is I originally worked in Unity, where ScriptableObjects did not need to be initialized at runtime and could be plugged into Components attached to the Actor (GameObject). Here, I need to instantiate the classes at runtime and put them into a TMap to get the same features.

[spark steppe]

i think the problem is just that changing stuff does rerun the construction script, but NOT recreate the actual actor

so the actor is still somehow referencing what you created in a bunch of construction script runs

the way around this is to wipe what you created

[heady terrace]

Yes I know, but from what I read Data Assets do not have access to visual editing. And I would like to have that instead of rebuilding the C++ code every time I make a change.

well, what I have works for now. I will re-examine Data Assets at a future date. It's been great talking with you guys!

[loud cipher]

anyone know how you can have a system where if you shoot a ai

it plays a animation of the character being shoved backwards

like a hit reaction

But only on the first hit, so the character doesnt get spammed with a animation of being hit

if the weapon is full auto

[plucky copper]

do once node and play montage node

@loud cipher

[loud cipher]

Okay thanks

[mossy jolt]

Is it possible to reparent a BP when the class doesn't exist anymore ? I can't open it

[hard charm]

Guys, how would it be to make a locomotion for different weapons that my character can take

It would be to put it in an array the animations and there take the animations that correspond to me or it would be to create a super state machine

[mossy jolt]

Well, i will recreate everything and never refactor again i guess :p

[sand shore]

no, but if you have another class which is memory & layout compatible you can redirect old -> new

But it only works if you have the same fields & functions & stuff (the new class can have extra)

[mossy jolt]

Hum should i use the path ?

[sand shore]

https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/ProgrammingWithCPP/Assets/CoreRedirects/

[mossy jolt]

I saw that yep, i tried +ClassRedirects=(OldName="OldProjectName",NewName="NewProjectName", MatchSubstring=true)

[glossy glade]

Is there a way to create a reusable color that can be referenced in blueprints and materials?

[real tree]

I got a question. I moved the third-person camera to a separate blueprint and I'm using it as a child blueprint on my pawn, so I don't have to duplicate logic between multiple pawns, but I'm having an issue where the Add Controller Pitch and Yaw Inputs no longer work, and the camera is locked behind the player. How would I go about fixing this?

[sand shore]

Yes, several, and which method to use is mostly up to your use case. What are you trying to do

[glossy glade]

I want to have reference to an Ally and Enemy color for use in HUDs, decals and the like

And If I want to adjust one of the colors I don't want to go chasing down everywhere I show them

[glossy glade]

So whichever method is lightweight and can be referenced in blueprints, materials and ideally material instances

[sand shore]

make a blueprint function library and in that make a function. It should take either a Gameplay Tag or an Enum or whatever, and should return a FLinearColor

It can be pure

You can then use that wherever you like in BP to push material params. Have any material that needs it take a color param which you can set by name from BP

You almost could use a material parameter collection but would still need to tell every material which field to use (what team they're displaying)

Now, your game systems can keep using whatever they were already for team identity and you have a centralized place to handle team colors

plus you can either make that library a TeamHelpers lib and also provide team names and icons in this way, or you can lean into that function library providing utilities for setting up material instances in general (a portion of which is the team color)

There's a more scalable alternative but it's quite heavy and nowhere near this simple.

downside is that you have to use material instances and can't ever just use basic materials or textures

[runic plinth]

I have a spline drawn in "S" and sometimes when following the player it jumps on the curves and doesn't keep up with the player. Is there a way to improve this behavior?

[jovial dirge]

what is wrong with my logic? This isn't working

(to get the amount of rooms entered)

[sour ridge]

If in example in an Array For Each Loop, inside the loop body you do Remove Index for the array you are using for the loop, does it fuck with the For Each Loop since you remove an index from it? or the loop continues normally.

[jovial dirge]

@sour ridge Not entirely sure what you mean, but did some more testing and randomly the value would reset to it's default

[sour ridge]

so in example, this screenshot am I better off doing a 2nd loop which removes index to not temper with the For Each Loop of the first one? https://gyazo.com/6c8956475acca7e8f905260f3a7d1fa1

[jovial dirge]

so I would just do the same for the amount of rooms entered?

Why wouldn't this work?

[sour ridge]

@jovial dirge your goal is to add +1?

[jovial dirge]

yes

just everytime

add +1

[sour ridge]

is it adding more than 1?

if so check your box collision to maybe not trigger on any actor collision

[jovial dirge]

no, sometimes it adds none ... or I think it might be getting set to default amount

No it's not the boxcollision becuase everything else after that is executed fine

[sour ridge]

maybe it collide with all actors

I see

if it adds +0 does the rest of the bp works? or all of it doesnt work for you?

[jovial dirge]

Yes it always works it's only the integer that is messing up

I think it's getting reset to it's default value

[sour ridge]

if you want to check where else you are using that variable, you can right click it, find reference, if no reference shows up in the same BP, you can click the binoculars to find it in another blueprint (Gotta check if its the same variable of the variable you right clicked (applies if you create same variable with same name elsewhere)

[jovial dirge]

Yeah there's no other instances of it unfortunately

[sour ridge]

@jovial dirge I don't necessarily see how it would fail except checking your collision settings or posting a bit more all of the blueprint that function does

just showing Variable = Variable + 1, itself it should work

also the first post I made wasn't an answer to your post XD more like a question I was asking also 😛

[brazen pike]

Try printing when it's executed to see what amount is added and another print to see what number it's being set to

[jovial dirge]

Hello I had another quick question if you don't mind
I need to get all of the undead monsters and then perform a check every tick for when the amount of them is = 0 how would I accomplish this?

https://media.discordapp.net/attachments/879969325178572841/879969452580565052/unknown.png

[gentle urchin]

On monster spawn -> Subscribe (add self) to a list in whatever actor that needs to check the amount.
On monster death, unsubscribe (remove self) from the list

Why must you check every tick?

If you wanna start respawn stuff then you can do a timer/delayed respawn in the monster actor itself, or via said actor that controls this

[surreal peak]

[pliant tendon]

is it possible to make control rotation rotate around a specific axis, for example say my player is upside down, how do i make it so that the control rotation is upside down too?

[gentle urchin]

Add rotation to the input vector direction

[surreal peak]

By calculating it yourself instead of using "AddRotation" for example.
But this smells like you'll soon face gimbal lock

[gentle urchin]

Dont think thats needed when using the "get forward" vector tho

[surreal peak]

I only ever did this stuff with Quats

[pliant tendon]

to the control rotation?

[bright surge]

hello! I need help, I don't know anything about blueprint, how can I link the location of point lights or any spot light to the Skylight angle?

I don't know what to do now

[gentle urchin]

Nvm, i misunderstood the question 100% 😛

[pine herald]

I didn't understand what to do with the lights ... Do you always want to have a light that follows the character?

[pliant tendon]

and i was excited that someone found a solution xd

[bright surge]

I want when the skylight rotate its angle, the spot lights that I created follow

[pine herald]

Can you send some screenshots of the scene?

😅

[bright surge]

here is the screenshot

[pine herald]

Do you just want a light that revolves around your character? To your magnificent character, congratulations ;D

[bright surge]

yeah I want the lights that go around the character

with the skylight change its angle too :p

[pine herald]

mhh

[pine herald]

Have you already created the variable? I think you have to make a variable and that the light follows those coordinates that change precisely from the variable

IDK

😅

hey thanks a lot man, I will watch this

[pliant tendon]

is having too many branches bad?

[pine herald]

To me personally yes, I try to summarize everything

I guess I also scam the pixels of the monitor

[pliant tendon]

im using about 12 branches, 4 of which are in tick

is it bad for performance?

[gentle urchin]

Not by itself

[pliant tendon]

and 2 linetraces and some simple maths

[gentle urchin]

no prob

[pine herald]

I have no idea, I don't even know UE5 so I don't know if the game does when I put too many branches ...

For ticks it seems to me that you can only put 1 for Blueprint, so I think that's fine

[gentle urchin]

branches are very cheap by itself... they're just "jumps" in the code

[pine herald]

They are events

[pliant tendon]

nice thanks 🙂

[gentle urchin]

How are they events? They're not callable by any means

[pine herald]

I meant
Event begin play
Event tick
Custom event
and everybody else, bro get yourself a chamomile!

Here you are, drink and calm your minds

[gentle urchin]

Right, but he asked about branches , if they were bad for performance 😛

[pliant tendon]

thanks for the chamomile mmm tasty

[pine herald]

And we both answered him 😝

It wasn't for you, but I'm glad you liked it 😂

[barren whale]

When I create a new blueprint I can't find it in the place actors window, if I place it from the content browser into the level then it appears. When I restart the engine then it doesn't show up in the place actor window until I use my test blueprint. Is this only happening for me? I tried googling about it but I can't find anyone mentioning this issue.

[pine herald]

🤷‍♂️

[surreal peak]

Isn't that just a list of recently placed actors?

[barren whale]

is it? My c++ actors always show up in this window (even when I've never used them yet) so I just assumed it was a list of placeable actors

Hi guys, a newbie question, i want to start an action when the game start but the event begin play it's already fired in this blueprint, how can i start the logic?

i want to fire the linetrace when the game start

[fiery swallow]

Option 1. Add it to the end of the beginplay line,
Option 2. Create a sequence after beginplay that calls everything you need

[solar sleet]

add a sequence node or put it after the 'should rotate event' node

[fiery swallow]

https://gyazo.com/723faa97f92e85414ae965499f4f341d

[trim matrix]

a ok, so the logic is that the begin play can be called only once in a blueprint

[solar sleet]

Yes

[trim matrix]

then the logic need to be applied following that right?

perfect

thank you : )

[barren flower]

Hey guys, I have a weird one

I want to be able to draw on any surface I shoot with a line trace

I just want to change single pixels, or very small anyway

So point gun at wall, shoot a line trace, that spot turns red

Now, I understand render targets can do this, but does that mean I need a render target on every single surface on every single object in the entire game?

Can I incorporate a RT into a material and make it an instance or will all of them update at once?

Really appreciate the insight!

[gentle urchin]

ping pong

Minesweeper, tertris etc

relatively simple. Involves some spawning, some UI, some bounce at a constant velocity etc

[orchid star]

In theory yes

but Im not expert on material coding

Or you can maybe try decals

but it might not be optimal im not sure

[barren flower]

Yeah its rough, decals might work but I dont think they are going to be performant. I actually am currently spawning sprites, but again, I want to be able to draw to the material/texture directly to use it as a mask later

[runic plinth]

Joining in for some ideas, how would I set up a box collision to be static and yet detect physics / hit collision to output the player velocity? (basically detect how hard the player hits the wall) I keep getting this warning but I don't want the box to move.

[barren flower]

On overlap - > is player -> get velocity or whatever

Calculating physics is expensive, you shouldnt have some random box doing physics calcs. Just use overlap triggers!

[runic plinth]

But I need to know how hard player hit the wall ..

[barren flower]

Right

[barren flower]

So you are currently doing that by having the player add impulse to the box, right?

Right, so you are getting the component velocity

[runic plinth]

No idea I just enabled physics on the box and get the velocity

[barren flower]

So instead of on hit, use on overlap

Wait even on hit should work, why are you adding impulse to the box if you dont want it to move

[runic plinth]

How am I adding impulse to the box?

[barren flower]

You tell me, you're the one with 5000 errors telling you thats what you are doing

[barren flower]

Literally read this

[runic plinth]

That's the problem. I don't know how supposedly set that on, I just pressed enable physics and changed some collision settings

[barren flower]

Also you are getting the component velocity of the box, not the actor hitting the box

Right, so disable physics on the immobile object

Get the velocity of the other component, not your own

[runic plinth]

something along those lines?

[barren flower]

put a branch in there in case that cast fails if you want graceful errors, but yeah

[runic plinth]

That only gives me the direction player is facing when rubbing the wall

[barren flower]

No, it should give you the velocity of the player

Try running into the wall really hard

[runic plinth]

If I running dead center I get close to 0 values if I am "side rubbing" I get up to 90?

not sure if velocity is what I need

[warped quail]

Hi, since a long time this is all we see in our Blueprint Debugger call stack anytime we want to use it. Any ideas why?

[random quail]

What is the reason why 'Get Class Defaults' node for the field of type TArray<UDataAsset*> (editable uprop) triggers @@ has an unsafe connection to the @@ output pin that is not fully supported at this time. and are there any workarounds or a way to silence warn since it is a read-only use?

[heady burrow]

Holy shit, I spent a long time trying to understand why my char wont move to a specific point..

[fleet mauve]

Hi everyone. I'm currently trying to switch cameras in a level blueprint by pressing a button. I've gotten the first part to work (switching to the second camera), but when I press the button again I want it to go back to my first person camera. Does anyone know how to reference the first person camera in a level blueprint? Or how to switch back to the first person character. Here's the code I have in my level blueprint at the moment. Again, part A works, just need help with part B.

[fiery swallow]

I think you'll need to cast to your character and get the camera from there

[fleet mauve]

I just took your advice, but my first person camera won't connect to the "New View Target"

[fiery swallow]

zzz... I see "New View Target" Is looking for an actor, not a camera. You need to plug your controlled pawn into new view target

https://gyazo.com/4aaa7752eff374b873c3bdeb624f4656

[fleet mauve]

Hmm just tried it and it doesnt seem to be working

[fiery swallow]

I just tried it in my project and it worked fine, could it be because of the blend settings you set?

New view target just needs to be whatever actor you want to get the camera of

[gentle urchin]

Thea_currency_test

in this case i think

but not really,

since its a controller, and shouldnt have a camera

You could do "get player camera manager" tho

[fleet mauve]

I probably shouldve sent a screenshot of what i did . Here's what i have so far

[fiery swallow]

I tried the one and it didn't work, getting controlled pawn worked, or casting to an actor

[gentle urchin]

Input mode UI only also blocks input to the pawn...

Pretty sure im using camera manager in my project.... ..

[fiery swallow]

Set Input mode ui only.. can you disable that and try again?

[fiery swallow]

Perhaps, im not saying you're wrong. I'm just saying that didn't work when I tried it

[pale orbit]

How can i handle different game modes on the same map?

[fleet mauve]

Yess it worked!

I guess the input UI was causing issues

[fiery swallow]

Yeah you'll just need to re enable input after you're done with ui stuff

Or have the ui automatically place the camera back to normal

[fleet mauve]

Yeah the reason I had that there was so the player wouldnt move around when going to that second camera

But im just happy its working as of now ill cross that bridge when i need to lol thanks again

[gentle urchin]

Just checked , and you're right Moxie ^^

PlayerCameraManager seem to hold the current camera ref, nothing else

never really used the manager beyond such a test 😛

[sacred minnow]

guys i made a fully working stamina system and i works fine, now i'm trying to add a simple feature, every time the stamina bar is full i want to hide the stamina bar, and only make it visible when the bar is below the value 95 (100 being the max), im bad at BP's,

so i suppose i need to and a branch with (if integer <= 95) to set visibility) and connect it to return node?

thanks in advance

[gentle urchin]

I'd suggest doing it on an event based setup and not using the bindings but...

if you like bindings then you can add another binding for visibility

and as you say, just do a is Health >= 95 boolean, connected to a select into the visibility

Or branch and hardcoded visibilities

[fiery swallow]

https://forums.unrealengine.com/t/openlevel-with-options/41808/3

[gentle urchin]

think the latter is less expensive

[sacred minnow]

ok let me try, thank you

[icy pilot]

Doubt

[random quail]

why you would think so?

[feral ice]

hello i have been strugling how to get this to work. Spawning a lot of line traces just shooting down and center is the red.

I came up with this

but when i just drag the location away from 0(in y axis) the distances bwtween each line in y axis gets larger. It should always stay the same

like this

[maiden wadi]

@feral ice I would recommend something like this to simplify your math a little. Should also do what you want with the same inputs you're using.

The above will also rotate with the actor if you need it to.

[rugged wigeon]

does ue4 have any built in bp funcs that take an integer, increment it, and if it's greater than some threshold, going back to a min value? Or more literally, incrementing through an array and hitting the first element if it's at the end?

don't need guidance on how to do that. just curious if there's something built in.

[last abyss]

it keeps increasing because of: distance between each + temp y + actorlocation(Y) = temp y so if actorlocation Y is 20 and say distance between each is 20
20 + 0 + 20 = 40, first time
20 + 40 + 20 = 80, second time
20 + 80 + 20 = 120 third time
etc. basically the actor location drives the distance, not the distance between each using that method. all you really have to do to fix it is move the + node before setting the temp y to the make vector Y to fix your problem.

[white field]

quantize

there are some quantize nodes as well

[runic plinth]

So my AI goes through walls like they don't exist. Walls block the player but not the AI. Kinda first time I work with AI, for what and where should I look?

[gentle urchin]

Nothing built in for that

[maiden wadi]

Select node.

About as close to built in as you'd get for that.

[dawn gazelle]

There is the "wrap" node that will take any value and map it to between a start and end value, but it doesn't seem to work correctly (it'll give starting index +1 when at the max+1) (Min at 0, Max at 100, input value is 101 it'll return 1)

I did make myself a function in a library that works though:

So say you have Min at 0, Max at 100, and your input value is 101, it'll return 0. 102, it'll return 1. etc.

[feral ice]

ok thank you for the solution!

[feral ice]

how do you mean? Move which +?

[trim matrix]

Hi everyone, so i was cleaning up and moving some stuff into my project, i'm very new so i was trying to not broke everything lol, i was almost done everything is ok aside the thirdpersoncharacter blueprints

get messed up a bit

[last abyss]

hopefully this makes sense, the same at the bottom make vector

[trim matrix]

this is actually my thirdperson BP location

[feral ice]

it kinda worked still some bugs but your solution solved it. But how do i add an instance at each point?

[last abyss]

that wasn't my solution, but if that works its better right?

[feral ice]

i just replaced all your "make literal" with variables.

but you see the points where it hits here. I want to spawn a grass mesh on each point. How do i do that?

it spawns it out of place and spawns a lot of them in the right corner

[pearl beacon]

Im having some issues on my inventory function for dropping a item from slot, so when its dropped, it spawns the item into the world, but as long as there is no item actor in the world from scratch it does not spawn it, anyone have a clue why?

[maiden wadi]

@feral iceThat node uses a difference space. If you want to do it off of the return location of the trace, use AddInstanceWorldSpace. Otherwise you need to convert the trace location into the local space of the ISM Component.

[cyan schooner]

Any reason why my animation blueprint would break after migrating to another project where I have the same skeleton, anims and statemachines setup ?

[feral ice]

ah i see! It worked

[maiden wadi]

Most ISM or HISM component stuff is optimized to work in the local space of the component.

[dawn gazelle]

Copy and pasting between blueprints can sometimes do this as the referenced objects / variables don't exist.
You just need to fix up the issues you have by reviewing the errors and resetting the values that aren't correct.

Eg. This first node here no longer has the save game object class set in it.

And that has a cascading effect on the rest of your issues.

And this one here, you need to recreate the cast to the appropriate save game class.

[odd roost]

Hi All, does anyone know how to fix this issue? I have 3 component sections of my landscape where it's visually just off from the other component sections

[tight schooner]

I have an esoteric question. I made a blueprint child class of a Hierarchical Instanced Static Mesh Component that has some mesh & material & collision settings pre-configured. (It's a data-only BP.)

I can do that, right? Like UE4's not gonna explode?

Are there limits to BP-subclassing things like mesh components? Like, could I put functions in there?

[brazen pike]

That's something I wanna know too... I'm sure it's possible because it would be stupid if not

The UI seems to suggest I could put functions in a mesh component subclass. My question is whether I should

Character BP Side

ItemBP side

Im having issues with a error reading following

[tight schooner]

"Accessed none" means there's no data. Your "get actor of class" node isn't finding an ItemBP

[pearl beacon]

Okey i switched it to cast to ItemBP, made a variable ItemRef, and set the type to Item BP, but it still reads none, why is that?

[tight schooner]

The basic issue seems to be there's no ItemBP spawned into the world; it can't get an actor that doesn't exist.

That's all I can say from my end

If an ItemBP does exist at some point, maybe you're calling GetActorOfClass at the wrong time, like before it exists or after it's destroyed; idk.

[pearl beacon]

Does it require an actor to be in the world at all times?

[tight schooner]

Only when the node GetActorOfClass is called, and any of the nodes using the reference that pops out of it.

The reference becomes invalid if you destroy the actor ofc, but it seems like GetActorOfClass isn't finding an actor to begin with

[feral ice]

why does it create a lot of static mesh at origin(0,0,0)

[pearl beacon]

ye i traded it out for a "Cast to ItemBP" instead,

but the ItemRef is not finding anything

[tight schooner]

All that "Cast" does is check if a supplied object reference is of a certain class or not... it won't do a better job at finding an actor than GetActorOfClass per se

[pearl beacon]

Okey so im better off just using Get Actor of Class and just storing a itembp underneath the map to tackle the issue?

[tight schooner]

Maybe. I don't know anything about your project, but if an ItemBP is hand-placed into the level and you use GetActorOfClass, it'll return a reference to whatever ItemBP happens to exist in your world.

(If there are multiple, it arbitrarily picks one.)

[pearl beacon]

Nah, i got one but im trying to make it so that upon the function to "dropfromslot" is triggered, it will clear out hte slot, and pass the variables over to an item that is to be spawned into the world

[tight schooner]

I'm kind of baffled looking over your screenshot... It looks like you got a function in ItemBP that spawns an ItemBP

but ItemBP #1 can't spawn an ItemBP #2 because ItemBP #1 doesn't exist yet

[pearl beacon]

Yea, i am i supossed to keep it in ThirdCharacterBP?

Oooh, so i need to pass that functionality over to my characters bp?

[tight schooner]

Yeah, or otherwise something that already exists in the world needs to execute the spawning code

Can't really say structurally where it should go cuz I never made an inventory system myself

[pearl beacon]

Oooh ok, my bad, i will do this now then, cheers

[tight schooner]

You should debug it; make sure every part of that node graph is doing what you expect; producing the values you expect etc... I can't debug it myself merely by looking at your screenshot.

[pearl beacon]

welp, now its just picking it up at once when dropping it

[cursive path]

I have question abount widget how to make it so big and move inside it by mouse

[pearl beacon]

What do you mean? you can resize it as a window, inside the ui editor, and you can use "Set Show Mouse Cursor" to get the cursror active

[cursive path]

I know this but i mean that i want to be like window when i move up

Similar to scroll to all side

Seem i bad in explaining

[pearl beacon]

Yea, its a little hard to understand you mate, my bad 😅

[cursive path]

Do you know salt and sanctuary game?

[pearl beacon]

i dont im afraid

Hi sorry in advance for the very NOOB question but I am trying to cast to my Behavior Tree service to get access to a function. Question is, what do I use as an object for the service cast. I tried a Blackboard reference, no joy... so what to use. Thanks

[coral sand]

how could i access or generate the average of the 3 vertices of the current primitive in a material

[upbeat otter]

How can I "save" a variable to another level such as a simple text string in a widget containing a url

[earnest tangle]

If you're opening them as separate levels, easiest way to do it is probably have a variable on your game instance class and save it there, since the game instance persists between levels

[upbeat otter]

yeah i tried it and it working but I just dont know how to replicate it now, thanks for your help though

[iron heron]

i am stupid

yes my indexes were inverse

Trying to do an onclicked for an actor. Static mesh works but skeletal mesh wont, how can I fix this?

[signal warren]

hi
i'm currently having a Player Character who can equip/unequip a sword actor

should i use child actor or just use actor?

i've read that child actor is more expensive than traditional actor and have limitations (i've have to change my bp graph to fit with the child actor function)

[fiery swallow]

Well if you have multiple swords you really should be going with child actors... And what limitations?

[runic plinth]

if anyone here, how would I simulate higher velocity for hit events if I won't allow sprint? I was thinking something like get distance traveled in a straight line and get that value to add into the normal player velocity but I think it's redundant. Any ideas?

[civic briar]

How can I make the debug capsule follow the rotation of my characters pawn?

[shadow root]

try doing the same thing you're doing with the location but with rotation. get the capsule component rotation and plug it into the draw debug rotation

[civic briar]

That just rotates the capsule in place

@shadow root

[atomic salmon]

Or just directly make your capsule component visible in game

[civic briar]

I did that but im creating an offset from the capsule

If i move the capsule itself it moves everything because its the root component

i tried to draw it from the camera itself.... but take a look at my problem in #ue4-general

[shadow root]

are you adding a value to the rotation the same way as the location? that could be what's causing it to spin

[atomic salmon]

Yes I see that now. The debug capsule is always in world space, so if you are trying to have it displaced to the right of your character you need to use its right vector to offset it

[civic briar]

All I did was plug in the relative rotation from the capsule to the rotation in the draw debug

@atomic salmon I am using the right offset based off the relative location of the capsule component. When i try to get the relative pos from the camera, it doesnt use the camera im specifying

weird

[atomic salmon]

If the capsule component is the root, its relative location is in world space

[civic briar]

This works using the capsule component location but it does not work for the relative pos of the camera for some reason

image above does everything but rotate around the capsule in the direction of the camera (which is what i am trying to achieve

Can someone tell me where the random Camera Actor is coming from ?

[atomic salmon]

Are you possessing your pawn?

[civic briar]

yes

everything works fine as well

unless i try to reference the camera in BP

it gets the wrong camera ? even though it says it is getting the one inherited from the cpp class

[young oriole]

I'm following a tutorial and I notice his SplineMesh is under his arc_spline but is not. and it won't let me drop in there. Does this matter at all?

[atomic salmon]

Is that derived from Character or a custom class?

[civic briar]

Custom class

whats weird.... if i (get) the camera relative location and print the position... it shows the correct position

[atomic salmon]

There may be something in code which activates and external camera

[civic briar]

Could the camera be automatically spawned from the character movement component ? I used a Character class when creating this

Maybe i didnt answer you correctly to begin with

[atomic salmon]

The standard Character doesn’t have an “external” camera.

[civic briar]

hmm.... then wtf is happening lol

[atomic salmon]

Unless it’s using a spectator mode

[atomic salmon]

But you need to transition the player to spectator specifically for that to activate

[civic briar]

I am using this in the cpp to auto possess

[atomic salmon]

Something strange is going on. That part should be fine.

[atomic salmon]

Where does the CameraActor come from?

[civic briar]

noooo idea lolll

i have the camera in the .h and then i set it up in the constructor in the cpp

[atomic salmon]

I would create a separate test level, place just your character in it and test it there

Or delete the CameraActor from this one if you don’t need it

[tawdry raft]

Sorry to barge in here but anyone know how I can make a actor rotation loop whenever I'm locked onto a target?

[civic briar]

i cant delete the camera actor because its automatically spawned; if we are talking about the same camera

[atomic salmon]

FindLookAtRotation on tick

[atomic salmon]

Ok spawned by what?

[civic briar]

New level.... No change

thats the issue. Idk where the hell its coming from

[tawdry raft]

Where would I place that in here?

[atomic salmon]

Then it is spawned by your character @civic briar

[atomic salmon]

You already have it

But it is linked to an input

If you want to lock onto your target that code needs to be called on tick

[civic briar]

I don't understand. I have a camera component on the character BP in the scene. This is other camera is separate and i have no clue how its getting spawned

[atomic salmon]

@tawdry raft As long as you want to maintain the lock

[tawdry raft]

I want it to maintain the entire time the camera is locked on, but now that I think about it, I will instead go for when the button is held

[civic briar]

So i have confirmed that 2 seperate cams are in the scene at runtime

[atomic salmon]

So from the button you set a locked Boolean to true when pressed and too false when released. Then from tick you run that code if the Boolean is true

[civic briar]

Get this when i try to delete it from the scene at runtime

[tawdry raft]

Alright, gonna give that a try!

[civic briar]

Where does PlayerCameraManager come from

[atomic salmon]

Ok, do you have a custom player controller?

Or a custom game mode

[civic briar]

When you say "custom" do you mean... made from c++ NONE or c++ Character class and i created all the functionality myself

Also, i created a BP gamemode derived from the default

[tawdry raft]

I may have messed up

[civic briar]

Okay maybe its coming from here

[atomic salmon]

All I can think of being 4 AM here is that there is something wrong in your custom character which triggers some default code somewhere

Maybe you can try with a default character and see if it still does it?

[atomic salmon]

You need an On Tick Event

From the input event you just set the Boolean

Then from On Tick you check if that Boolean is true with a Branch

If it is true you run your rotation code

If it is false you do nothing because you are not locked to the target

[civic briar]

Heres where its coming from

But why is this code being executed

[atomic salmon]

That’s the standard Camera Actor, but usually it doesn’t spawn by itself. Looks like something is spawning it.

[civic briar]

This is default. I think its referring to the Character class camera

But like you said. It shouldnt be auto spawning

[atomic salmon]

I think the camera manager is spawning that camera actor because it doesn’t recognize the camera within your character

[civic briar]

Potential UE5 Bug ?

[atomic salmon]

Or double check your code

Sounds too obvious to be a regression

[civic briar]

I have triple checked it

unless i am doing it wrong and dont know

Header

[tawdry raft]

Did you mean Event Tick?

[civic briar]

cpp

[atomic salmon]

That’s why I was suggesting to try with a standard character

[civic briar]

thats the only place

[atomic salmon]

Yes

[tawdry raft]

I already have that for the camera targeting attached to a sequencer, but it's fine if I copy it and paste it for the SetActorRotation?

[civic briar]

Actually idk if its my character class calling it. I check in a new level and changed the gamemode back to default and to use the spectator gamemode and the random camera actor still spawned in the scene

[atomic salmon]

Yes. Just make sure you don’t break the sequencer part of the code

[civic briar]

https://answers.unrealengine.com/questions/588156/camera-actor-spawning-at-the-start-of-the-game.html

Seems to be a known issue

[atomic salmon]

It happens when the camera manager cannot find a player camera

[civic briar]

I see

[atomic salmon]

Need to catch some sleep now sorry

[civic briar]

Thanks for the help though

[tawdry raft]

Thank you, I'll get this working eventually

[civic briar]

Ill hit you up when i find it lol

[atomic salmon]

Please do!

[vocal urchin]

How does one show splines at runtime? I just need a debug visual.

[burnt citrus]

Hey I need help
I'm making FPS with TP Mesh
Then I have to make FP weapon and TP weapon effects synchronized
but I have no idea... is there good idea?

[atomic salmon]

@vocal urchinyou can issue a show splines from the console at runtime.

Or use a Execute Console Command node and do it from code

[vocal urchin]

Good call, thanks 🙂

[astral stirrup]

hello, good morning. im having some issues referencing a texture2d by name. i have a few exr files created by unreal, with some numbers in the name and using import file as texture 2d and giving it a full path (as a string) doesnt seem to work for me in this instance

[void needle]

does someone know why everything reflects light, and how ti fix it?

[astral stirrup]

classic, when i finally ask i figure it out somehow 🙂 seems my export was a bit off, changed min alpha, and set it to ui element. one of these worked for me

[void needle]

okay, i fixed it

[amber rock]

hi people, I trying to set default value for inherited variable in constructor, but i can't figure out how to do that? is it even possible ?
i had config and i want to transfer some varibales from config to blueprint. I created same variable in base blueprint class, and trying to find a way to set default vaules in cgild classes as copy of config values

[astral stirrup]

one last question on the matter, do i have to use the ImportFileAsTexture2D if the file is already an asset or is there a faster way of doing it? even with 10 icons it causes a hickup every time i open the menu

[vernal ore]

Does anything look wrong here? My vehicle wont move at all

[astral stirrup]

do u have ur axis defined in project settings>input?

[vernal ore]

I do

[astral stirrup]

the only other thing that comes to mind is some setting in the vehicle movement component

but maybe someone with more knowledge could help more

[vernal ore]

My wheel rotation works, I just wont move 😢

Anyone know?

[stable fjord]

how to turn off foliage movement in UE4 for whole project?

[lost solstice]

how would one go about properly using a player controller component... It seems a bit complicated just looking at it

[lofty hound]

Whats the logic for determining crit chance? i have a character with 5% chance to crit, how do i implement via BP?

[astral stirrup]

@lofty hound try RandomIntegerInRange node

combined with a branch node to test against your chance

[fiery swallow]

Are you talking about just playercontroller blueprint?

[lost solstice]

yeah that one

like why is there a camera and such

[fiery swallow]

The camera in the player controller I believe is what allows the actual player to see through camera actors, or pawns that have camera components. It's not really something you need to worry about unless you plan to switch viewing cameras between different pawns

[earnest tangle]

I don't think there's a camera on the player controller?

It's just in the pawn

[fiery swallow]

I don't think he meant an actual camera, but there is something like it in there

[earnest tangle]

iirc it has a camera manager or something like that, which is used for the purposes you mentioned yeah

[fiery swallow]

@lost solstice
It's not really that complicated though, it's mostly the same as a regular character blueprint, It just has different blueprints you can use that are specific to the controller... You could actually script everything in controller the same way you can do everything in an actor... It's not really a good idea though

[sacred current]

Guys How Can I get the previous tick of a float variable on tick event and store it?

[earnest tangle]

Depends on what the variable is really

[astral stirrup]

@sacred current have 2 variables, before u set the current one, set the value of the 2nd one to what the first one is

[earnest tangle]

You need to save its value somewhere before you change it

[astral stirrup]

if that makes sense

[sacred current]

basically I have my speed char variable and I want to check when the speed is not increasing so i can trigger a stop animation state

[earnest tangle]

Yeah just stick it into a variable and compare

iirc there's a way to get the previous velocity from character movement comp as well

if you use that

[astral stirrup]

true u dont need the var for the speed coz the movement comp has one already

just save that value probably around the end of your tick event

to compare that when it fires again

i got a bit of an issue too, do i have to use the ImportFileAsTexture2D if the file is already an asset or is there a faster way of doing it? even with 10 icons it causes a hickup every time i open the menu

this is sort of what im doing atm

should i just bite the bullet, and keep using the import, just refresh the image whenever actual changes are made (since it runs every time the menu opens atm)

[earnest tangle]

I think the import func is for image files

so if you already have the files imported in the editor, you don't need to import them again

[astral stirrup]

how would i access them through this name lookup?

i feel like i went through the entire node list and couldnt find anything

[earnest tangle]

iirc if you want them in this fashion you'd need to use the asset registry

I'm not sure how much of that is exposed to BP's but at least some of it should be

alternatively an easier method might be to just have an array of textures in your widget, and assign your textures into it in the editor

it's a bit of manual management but it's the most straightforward way to do it

[astral stirrup]

ah fantastic thank you looking into it now

[quiet stag]

guys i am trying to use ALT MIDDLE MOUSE to move the PIVOT and its not moving the piviot point its moving the ENTIRE thing...in the blueprint

I GOT IT 😛

[astral stirrup]

trying to get it to work with a data table and i cant reference them now for some reason, made a struct for it, holding the setups and the appropriate image (texture2d object ref - same as in the import which worked) the rows in the data table are being found correctly, but the texture doesnt load

[south merlin]

I must of spent 5 or 6 hours trying to debug why AI Move To wasn't working with a flying enemy. Only to discover flying enemies dont' work with nav meshes. LOL

[rich crown]

Hello, This might be a noob question , but the default tab seems to be missing on the right, i want to add a mesh.

[lofty hound]

Any idea why this is working? right numbers are coming out but bool is always set to false?

[last abyss]

because everytime u run an execute node you get a different value from the random float in range

so when you print string it gives a random float in range, then when you branch it gives another random float in range.

Anyone else having that UMG bug... When you add a user-created widget inside another widget then you update something in the user-created widget it doesn't update unless you remove it and add it back again or restart the engine? (4.26.2)

[burnt nest]

#umg might know 🙂

[willow yacht]

what do you mean might know? I'm talking about the widget blueprint class

[burnt nest]

I mean that if you don't get any help here, you might try in #umg since it's UMG related. 🙂

[earnest tangle]

it's called Component Begin Overlap or something like that

it'll probably look something like "Event Component Begin Overlap (Name of your static mesh component is here)"

or that :)

[fallen glade]

does anyone know how to fix this error? Do I have to keep the scale to like 0.00001

np

[earnest tangle]

Yeah I don't think you can scale to 0 🤔

What do you need that for? Are you trying to hide it or something?

[fallen glade]

yeah it's just a mesh that i make appear disappear, an attack of opportunity marker if you're familiar with rpgs

[earnest tangle]

Ah

Yeah probably just hide it the regular way

[fallen glade]

fair enough, thanks! 🙂

done this to keep the animation

[runic plinth]

Hey all, these Do Once nodes are triggering twice. Any suggestions?

[fallen glade]

yes, you might have 2 actors doing the same thing?

if you place a break node on them where does the input comes from ? @runic plinth
