blueprint

[flint crypt]

Hey guys how could I set up an inventory system with a 3D preview that you can rotate?

[vernal lotus]

that's a complex problem

do you already have an inventory system?

[naive stag]

Not working

[vernal lotus]

sorry for a dumb questions

just need to know if you are starting from scratch

[sacred minnow]

hey i need help, and the faster the better, im trying to implement cars into my game, but im having a big issue, the cars work, the player as well, but i cant get the play into the car

im getting this error

i tried to following documentation of the creator of the pack but its outdated

help would be very appreciated, and thanks in advanced

[flint crypt]

I thought it would be, so I decided to take a look at the Horror Engine asset from the marketplace which is sort of what I am trying to achieve. I'll come back if I have any questions I cant figure our though, thanks @vernal lotus

[sacred minnow]

if anyone could help me, please dm me

[vernal lotus]

oke

[naive stag]

Im gonna randomly guess that the problem is with collisions

[sacred minnow]

how come?

[naive stag]

Idk until u show us the code it says the error is at

[naive stag]

in second error u most likely forgot to give reference to an object u want to send data to

[tawdry surge]

Can you show what you have now? The steps I just gave you should work fine

[sacred minnow]

when i click on the error it sends me here

and here

[naive stag]

The problem is that whenever i try to multiply it by anything, the end vector just goes to the upper right corner

[sacred minnow]

its casting to my player (i presume)

[naive stag]

Casts to ur controller and not u

[sacred minnow]

im kinda clueless im recent to coding

[naive stag]

idk tbh, im struggling rn myself

so i cant rlly help

im sorry

[sacred minnow]

i tried nothing happend

like this

[spark robin]

How do you add "handles"/gizmos to a blueprint that can be moved in the level editor? I can remember watching some UE5 project demo where they used gizmos i the 3D viewport to drive some Blueprint logic a while back.

[plucky dawn]

Silly question, and probably was asked before but I couldn't find a consistent anywhere. The official documentation of UE5 tells to use BP_ to create a new blueprint class (https://docs.unrealengine.com/5.0/en-US/recommended-asset-naming-conventions-in-unreal-engine-projects/), but if check the assets in the Lyra project, you see BP and B. Is there a new standard naming convention and the documentation is outdated or this is just something that eventually ended in the project and it's not official?

[copper steppe]

I'm thinking someone might have forgotten the P, maybe? Haven't had that project open myself, but I could see someone missing it once or twice?
But seeing as they haven't changed the conventions in the docs, I would assume that the conoventions are still the same

[elfin wolf]

you get it fixed?

[sacred minnow]

nop

still not working

[elfin wolf]

whats the name of the controller your player character uses? do you know

[gentle urchin]

If its 'Controller' then rename it

100% overlap

[sacred minnow]

i suppose your talking about this file

[elfin wolf]

yeah you want to cast your BP_BasePlayerController and promote the output to a variable

[flint crypt]

Hey guys, so right now, my loot items are instances of an actor called Base Item that are set and instanced on another actor (Base Chest) BeginPlay and I can't seem to figure out how to set up references- how would I begin to add this to an inventory component for my player character?

[sacred minnow]

still nothing

still giving me the same errors

[elfin wolf]

no, from "as Bp base player controller" connect it to a set dc_player_controller node

i assume you want dc_player_controller to equal your player controller

[sacred minnow]

like this i presume

[elfin wolf]

yes

[sacred minnow]

still nothing

same errors

idk if this is good information this screenshot:

[elfin wolf]

yeah that code is too complex to easily troubleshoot, youre gonna just have to rewatch the tutorial your watching or watch a tutorial specifically on casting to understand it

[sacred minnow]

sadly the documentation for this asset pack is outdated

damm

[elfin wolf]

how

[sacred minnow]

i followed this doc/tutorial: https://www.youtube.com/watch?v=HIEbU047Mm0&ab_channel=DigitalDiveStudio

and nothing worked

im trying to get in contact with the asset dev, but nothing, his discord is also dead

[copper steppe]

I don't know why it's so hard for me, but
I've made a RTS controller for a part of my project, everything works fine, however, I want players to be able to rotate the camera, this obviously messes up the direction the camera moves, so I tried fixing it, however I can't seem to get it right. I know I probably need to use the forward vector, but I can't wrap my head around how to do it 🤔 👀

This is a screenshot of forward movement, without considering rotation, any suggestions?

[tawdry surge]

@naive stag I made this quick. It' gives a line in the direction of the trace hit and it goes twice as far as the sphere trace

Impact point and location were giving bad values which is why I switched to getting the hit actor location instead

[topaz badger]

Anyone know how I can get rid of this annoying debug tooltip? It covers the entire node sometimes and makes it so I cant click it.

[slim fern]

top right unselect the debug object

[topaz badger]

ah wow i feel silly, thanks a ton

[slim fern]

no problem i tried to work it out for hours

[topaz badger]

haha, thanks for saving me that time

[trim matrix]

Hello! I have a progress bar that I have attached a binding to and my issue is, after my game gets paused, my function straight up stops ticking. If anyone can help, that would be great but I'm also not sure if this is the place to ask because it is in my UI widget

I'll also ask in the Ui section just in case

I know it stops ticking because after I unpause my game, the string stops printing

[naive stag]

I got your idea, I modified it and now it works perfectly. Thanks a lot

[vernal lotus]

ok

so how exactly do I get the CameraManager to communicate with my PlayerCharacterController and PlayerCharacter blueprints?

[cobalt rose]

Currently want to create my game state blueprint. I notice I can't override HasMatchStarted and similar in the blueprint.. I thought I was supposed to do that.. is it c++ only for that?

(I derived from GameStateBase)

[faint pasture]

uh, are you sure you're doing something where it has to?

[vernal lotus]

what exactly do you mean by "where"?

[faint pasture]

I thought all the match stuff was in Gamestate, not gamestatebase

Gamestatebase is the simpler uh... Base for it

[cobalt rose]

well, those methodes are def. in the GameStateBase

    /** Returns the simulated TimeSeconds on the server, will be synchronized on client and server */
    UFUNCTION(BlueprintCallable, Category=GameState)
    virtual float GetServerWorldTimeSeconds() const;

    /** Returns true if the world has started play (called BeginPlay on actors) */
    UFUNCTION(BlueprintCallable, Category=GameState)
    virtual bool HasBegunPlay() const;

    /** Returns true if the world has started match (called MatchStarted callbacks) */
    UFUNCTION(BlueprintCallable, Category=GameState)
    virtual bool HasMatchStarted() const;

    /** Returns true if the match can be considered ended. Defaults to false. */
    UFUNCTION(BlueprintCallable, Category = Game)
    virtual bool HasMatchEnded() const;

    /** Returns the time that should be used as when a player started */
    UFUNCTION(BlueprintCallable, Category=GameState)
    virtual float GetPlayerStartTime(AController* Controller) const;

[faint pasture]

What are you trying to do that involves PlayerCameraManager at all?

[vernal lotus]

I want to have 3 camera modes

1 deafult for aiming

[faint pasture]

You running a camera component-less setup?

[vernal lotus]

no

it's the default camera + spring arm

2nd mode where it follows character velocity ( can't control camera)

and 3rd where it locks on to the boss

and it all has to be a single camera too

[faint pasture]

If you're going for the camera manager approach I'd just lose all the camera components. Otherwise you can just move that camera component around however you want. I wouldn't try mix and match.

[vernal lotus]

oh ok

I'd rather do it all in the PlayerCharacter blueprint tbh

[faint pasture]

Yeah I'd do that. Just have some enum representing the camera state and switch on it to set things up.

[vernal lotus]

oh an enum

I was doing this:

but it seems kinda evil

[faint pasture]

Yeah dafuq

[vernal lotus]

which switch would that be

I see a million different ones

[faint pasture]

Make some enum with values like Free look, follow, lockon

E_CameraState or whatever

[vernal lotus]

it's this thingy yeah?

[faint pasture]

Then in the character bp make a function UpdateCameraState that has that enum as a parameter.

Then in that function, switch on the enum to do things (disable use control rotation on spring arm, whatever.)

[vernal lotus]

sry I never used enums before

[vernal lotus]

oke

[spark steppe]

1.) create an Actor Blueprint
2.) add an component to the actor (e.g. Static Mesh Component)
3.) Drag the static mesh component on the DefaultSceneRoot in the BP hierarchy to replace the root component (now the Static Mesh seems(!) to be the root)
4.) place the actor in an empty level, and change it's world transform (e.g. move it up)
5.) save and reload the map
6.) actor at 0,0,0?

could someone test this for me?

preferable on UE5

[faint pasture]

Read up on them first. Enums are like a bool but can have many named states

I stead of true/false, you can have Apple/Banana/Cardboard/Ferrari

[vernal lotus]

oooooooo

[faint pasture]

Whatever you wanna call them.

[vernal lotus]

that's

huge

oke

[faint pasture]

And you can switch and select on them.

[vernal lotus]

alright epic

many thanks

[faint pasture]

Switch executes a different path depending on the enum value. Select chooses a different input based on the enum value.

[high fractal]

Is it possible to get a reference to an object attached to a skeletalmesh's socket in runtime?

or an object attached to a bone

[faint pasture]

For example in my projects UI I have a UIState enum, with values InGame, MainMenu, SettingsMenu, etc. When I press keys like escape, it chooses a new Enum from the current Enum (state machine), and then a function runs that shows/hides widgets etc.

[lament ginkgo]

Making a game similar to a point n click adventure from the 90s. Basically it'll consist of like 4 chapters, and each chapter will be an entire level in UE. What would be the best way to setup default states for each chapter? Stuff like starting position, camera, inventory, etc. I was thinking variables in the level blueprint but I think you can only add defaults in the BP editor, right?

[copper steppe]

From what I can see the best solution for that would be
And then if true set the reference

[high fractal]

Thanks Benj! I am having trouble setting the reference. My object is an Instance of a BP_Weapon. I need a primitive component object reference for a trace component to work.

[spark steppe]

anyone?

[high fractal]

Not experiencing this issue Ben, sorry.

[spark steppe]

UE5?

[high fractal]

Correct

[spark steppe]

thanks for testing

[vernal lotus]

I'm starting to think enums aren't fit for this

[bronze quiver]

are yout trying to change the actor's transform?

[spark steppe]

yes, but it resets for me if i alter the actors root component

[vernal lotus]

cuz I need this to update per frame, always

for every state

and then also interpolate between states

[bronze quiver]

I think thats because you are trying to make the Mesh the Default scene root.

[spark steppe]

i'm pretty sure that it's causing it

i just want some reproductions before i submit an bug report

maybe even track it down to a specific change in ue source

[bronze quiver]

Maybe I dont understand the error your having.
All I know is, if I'm trying to alter the transform of the mesh, don't make it the scene root and it will remain the same. Keep the default root as is.

[spark steppe]

i'm not altering it in the BP

i'm changing the location of the actor in the world, and it wont save that location with a custom root component

[blazing beacon]

hey, I have a problem with the resolution of my standalone game. not sure if this is the right channel to post it to - let me know if I should rather use anoither one.
if I switch my standalone game to fullscreen mode with a 4K desktop resolution, it pins itself in the upper left corner of the screen and changes its resolution to UHD (I think), but never the fullscreen. can anyone point me into the right direction of how to tackle this? thanks! 🙂

[copper steppe]

Maybe something like #graphics ?

[faint pasture]

You don't necessarily interpolate between states, just interpolate the results.

When you crouch, you don't crouch instantly, but you can have a state bCrouched. Same idea

[slim fern]

Now my AI is moving to the first waypoint but after that it stops working if anyone can help i can post the Blueprints

[runic parrot]

Hi! I found myself doing this a lot

that being a print with a "Message-6 random letters"

so i can find that specific print later on with a "Search on blueprints"

does anyone know if it's posible to create a shortcut to a custom node that is the same as the print node but with -'6RANDOM LETTERS' As a default?

Or maybe just override the print node with that default text

[bronze quiver]

I know I can just flip the door around, but how do I get the skull to enter based on the players facing direction?

[versed sun]

Find Look at Rotation

start is the skull, Target is player

NM, i read your question wrong

i think you want something with Dot Product, i forget how it works

[trim matrix]

I don't understand how RInterp to works

Plugging in the right rotators it just snaps to the new rotation without any interpolation

It's the delta time and speed thing that's confusimg

[bronze quiver]

yea, I need to get the players position and some how get the positive/negative of the facing x/y direction and blend that with the key position.

Just need to figure out the syntax

[tight schooner]

Do RInterp on Event Tick. For delta time, use the output on the Event Tick node, or use Get World Delta Seconds. Set speed to 1 and then adjust to taste

[tawdry surge]

Get the forward vector of the player and the door. Plug them into a dot product node. Positive return value means one side, negative the other

[atomic solstice]

how do I change double precision float to float?
for some reason a code I copied won't connect the nodes (dot returns double-precision float but Set "current Speed" node asks for normal float)
EDIT: never mind, it's just a bug. I'm using UE5, I guess the code is from UE4 so all I had to do was remake the nodes inside UE5. I guess everything got upgraded to double.

[trim matrix]

thank you

[prime stump]

Hi, i have this timeline that has a 30 second float track on it which goes from 0 to 1, how can I make it so the cloud coverage is set to 10 by the last second of the timeline? right now it hits 10 at about 10-11 seconds into the timeline

[versed sun]

i think you want your Lerp A to be 0

[bronze quiver]

Thanks for the help. I dont think its working though as its being driven through the timeline node. It dot product did change the behavior though, it just started from the middle and didnt animate.

[tawdry surge]

You need to use the output from the dot product and do a >0 check
Use that in a branch or a select node to get it to animate how you like

[prime stump]

If i do that the cloud coverage variable will be set to 0 which i dont want, i need it to keep the current cloud coverage and add to it

[wicked osprey]

Guys, can you please upload a tutorial on a belated camera rotation. For example, when turning to the side, the camera will first turn and only then the character's body will turn behind it

[trim matrix]

Is there a way to know if a key is held?

[quartz mauve]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Game/Player/IsInputKeyDown/

[wicked osprey]

Is this done via IK or is there another method?

[bronze quiver]

Oh okay, and then just make a separate animation facing the opposite direction?

[tawdry surge]

Or invert the current one

[buoyant moat]

Hello ppl, does anyone have an idea why the BeginCursorOver event is not firing in game ?

• I have enabled MouseOverEvents for the Player controller
• The StaticMesh of the actor in question has its collision profile set to BlockAll

Is there something else I might have missed?

[zealous moth]

@buoyant moat add a print string. Iirc if events have no follow up they are ignored

@wicked osprey that can be done using the animbp.

[heady jay]

How can I attach a physics constraint to a player and object during runtime? Thank you!

[unique turret]

Hey guys, this is pretty basic stuff, but casting does my head in. Here's what I'm trying to set up: A light switch that will cast to scene actors (lights) and toggle them on and off. I have six different light styles, and have parented them all to a BP_lightsParent. I can cast from the switch to the parent no problem - I just can't figure out how to pass the command along to the child light actor.

[onyx frigate]

@faint pastureHello ! It works like a charm except the relative location of the radar is not taken in account

this formula

That's my local rotation rotation is seems

[potent laurel]

casting is not that sort of thing, ignore the word "cast" in that way. however you make the parent actors switch on do the same way for the child actors. i have very little info to go by here but lets say you make the parent class turn on by "getting" the light(parentclass) then "Turn on" function.
for the child you would also, "get" the light(childclass) then "Turn on" function

if thats how you are doing it

[barren relic]

I have a shooting animation and a running animation, can I use a blend space to have my character shoot while running instead of making a new animation for it

my game is on a 2d plane btw

[onyx frigate]

Guys, I have a radar which is working fine.
The pink dot in the blue circle is the position of the enemy (green ball) vs the player pawn.

but I want my radar to have a relative rotation and the point to follow it.

Any idea to do that ?

if instead of the point I spawn an actor attached to the radar (blue sphere, which is a child actor), the enemy indicator actor will be rotated as well right ?

[potent laurel]

can you show how you are doing the radar

try "FindLookatRotation"

then maybe "SetRenderAngle"

[finite island]

Hello peeps

I am trying to move to level 2, after i complete level 1, so everything working fine, except that when i move to level 2 , either the character freeze or the level 2 freeze
this is part of level 1 blueprint that moves you to level 2

any idea?

[hollow inlet]

sorry I know this is late, but look at how they do it in Lyra, it's pretty neat

[finite island]

?\

[hollow inlet]

i don't really know anything about level loading, sorry.. the 'delay' node is kind of suspicious

[potent laurel]

what blueprint is this @finite island

[finite island]

level 1 blueprint

the delay is basically related to "fade"

so at the end of level 1, it fade, then it moves you to level 2

[onyx frigate]

@potent laurel that's how I spawn/draw the point

[potent laurel]

can you show me more

[onyx frigate]

I am just missing the rotation to be able to show the enemy indicator correctly if the radar is rotated inside the pawn

[potent laurel]

what event

[onyx frigate]

Tick

changing the position of the indicator on tick

[potent laurel]

gotcha

[onyx frigate]

My radar is rotated toward the camera like this:

the red arrow indicats the forward vector of the radar

[potent laurel]

so its the enemy rotation thats wrong?

[onyx frigate]

If I leave the radar with no relative rotation the formula works pefectly

the location of the enemy indicator (which is shown rn in the screenshot doesn't take the radar rotation in account). it's as if the forward vector was still pointing forward

if the rotation would have been taken in account the orange cube would have been shown on the yellow dot

(which I added in paint)

[finite island]

any idea?

[onyx frigate]

but because my formula doesn't take the relative rotation, it is shown as if the radar was facing forward instead of it's relative forward: red arrow

see what I mean ?

and right now my radar has this rotation (and always this one):

i don't understand how I can use this rotation in the formula below

[gentle crest]

does anyone know if you can make a blueprint that has like a bullet mesh that will follow a line trace?

[unique turret]

Thanks for the reply - gonna play with that in the morning.

Question?: I have 2 actors, Host and Client. I'd like the Client to move closer to the Host each second, then stop when it gets to the host. What does this look like in blueprints using set location? Its for reelin in an lure.

Newbie here, which BP class do I put this into? I tried the level BP but it doesn't seem to work (cycles through each camera and takes a screenshot in run-time) https://d3kjluh73b9h9o.cloudfront.net/original/4X/5/0/2/502783cce00b6bf26d7baa8991e78d9ebb8e4303.jpeg

You must translate 3d to 2d space. Is tge radar not always facing 'north' as players forward?

[desert flame]

Stupid question but does gamemodes variables transfer between 2 levels? If not, where should save game variables for multiplayer?

In one game in multiplayer you teleport level to level, but need to still be able to store alive players and kick players etc.

[undone surge]

when im using a widget switcher if i create the widget blueprints to be switched by it do i have to create them as the children of the main widget blueprint or can i just make them separately and then drag and drop them under the widget switcher in my canvas panel

[bronze hill]

is there way to set 'owner' other than Possess? i only know possessing can set owner. in my case i need to control multiple pawns, i set 'owner' variable with player controller but it's not real owner.

[elfin wolf]

probably using a game instance

[desert flame]

But game instance isnt for multiplyer

[tawdry surge]

You can't possess multiple pawns at once. However you can set them to be owned by the pawn you are possessing.
Either by assigning it at spawn or using the set owner node

[elfin wolf]

it is, read into https://forums.unrealengine.com/t/storing-variables-in-multiplayer-over-multiple-maps/481349 or https://forums.unrealengine.com/t/transfer-a-variable-from-1-map-to-another-per-character-in-multiplayer/228057/8

I'm developing a TPS game and I have a camera related question. PlayerCameraManager has its own camera. I have two choices. Either I will not use the PlayerCameraManager and use the camera I added from the component, or I will remove it and use the camera that PlayerCameraManager added. What are the best practices here? For what purposes and how does it make sense to use the PlayerCameraManager?

[sudden nimbus]

just use the camera where you have it

use SetViewTarget on PlayerController as necessary since PlayerCameraManager is driven by PlayerController

no need to try to bend your gameplay code to whatever camera is in player camera manager -- most of the time its first one it finds on your PlayerController possessed Character

[sudden nimbus]

see the above, because i forgot to ping

That's the simple way and works fine in many cases, however the player camera manager has benefits if you want more control

[sudden nimbus]

yes if you start using its API directly you can do lovely things separate from playercontroller 🙂

[high fractal]

Been racking my brain for days now trying to connect Lyra's weapon setup to a combat component. All I need is a reference to a primitive object but Lyra has Lyra Equipment Instance Objects. I've tried putting the components on the weapons themselves but then I can't get the activate collision to fire at all. Anyone have a clue as to how I could proceed? Thanks!

[wild zodiac]

Hey anyone played much with generating splines? I'm trying to get my ai to do some 'dinosaur movement' behaviour, and get them to follow a spline! Unfortunately the spline I generate from path points along a navmesh suck and was wondering if anyone had any suggestions to be able to get a more smooth transition?

[sudden nimbus]

could be a great topic for #gameplay-ai

we love that stuff 😄

[wild zodiac]

Wasn't sure where to post, but I'll rehash that over there! 🙂

Can someone give me a lead how this pp could be done?? Id pay the person but his product and sells page has been removed from market place

[tawdry surge]

There's plenty of youtube tutorials on outline materials. Both post processing and otherwise

[sudden nimbus]

And there is also #hire-a-freelancer et al to advertise hiring requests

[trim matrix]

ok question but it is possible to make a blueprint that destroy a diffrent actor that isnt in the triggerbox right?

[thin panther]

Yes as long as you get its reference

[trim matrix]

I knew it! all i need is to figure out how to make tge reference

[compact thorn]

Hey guys Idk if this is the right channel for this, But iam having so much problems with the cars in my project I just cant make them to work. wheels turing wrong side they dont even drive, If anyone can help me I would really appreciate it

[slim fern]

well for one how is anyone meant to help when you dont post a blueprint or anything and also dont ask in multiple channels considering you posted 5 minutes ago in #ue5-general

[compact thorn]

There is littearly nothink in BP, you dont need just the animation BP, and the inputs for forward and steering stuff, I was asking in general if someone had that problem

[slim fern]

if theres nothing in the BP why are you posting in a BP channel?

Also how are you trying to move

[compact thorn]

Thats why I said idk if this is the right channel for this.. ahah nwm ill figure it out

[bronze hill]

Thank you very much!

[white elbow]

how do I detect if player stands on an object? (I need to make him unable to grab it)

[slim fern]

Trigger box

then override the on actor begin overlap and then disable grabbing

then on end overlap enable it again

[trim matrix]

Thanks a lot

[compact thorn]

Now for real, I figured almost everythink out, Now iam confused why my car only steers to right!

[thin panther]

Your a and d move in the same direction there

So does forward and backward actually

[compact thorn]

Ohh I see so I should just make 2 seperate line steering L and steering R

[thin panther]

No

Just invert the scale

On one

[compact thorn]

Ahhh thanks

[compact thorn]

Your a god love you❤

[thin panther]

No problem

[white elbow]

there's gotta be a way to detect the component a player is standing on through CMC

[lime yoke]

Guys, I'm trying to use the scale of the client start camera shake with a variable, but instead of using the value of the variable, it automatically changes to 0.

I'm not sure if this is a bug or what.

Version es 4.27.2.

[rich jungle]

Kind of a dumb question

Does changing a variable to the same value have a cost with regards to graphics?

Like if I go "set material" to the same material, does that have a cost or does the engine cull that call if it's un-necessary

[obtuse current]

Divide viewport size by it

[grave sandal]

ok, changed it, still getting stuck in the corners the same way, except with some margin :/

[zealous moth]

nothing happens. the address is already set so if you set it to the same thing, nothing changes.

[rich jungle]

thanks :)

[west sky]

Scenario! I have two BP scripts:

• ProximitySpin sets the relative rotation and position of its Owner using the "Move Component To" node
• ProximityFollow sets the position of its Owner using "VInterp To" combined with "Set Actor Location"

Each script has other logic associated with it, but these factors are the points of friction. I would like to apply both of these scripts to the same object and have their position-setting behaviors be compatible. If I were using Unity, I could create an empty parent object and attach one of the scripts to that and the other to the child. Attempting the same structure with these two scripts in UE results in wildly unpredictable behavior. Using both scripts on a single object causees one to override the other.

I've attached both scripts here so you can see what I'm up to. To use them:

• open a default Third Person project
• attach either script to a Movable static mesh actor in the scene
• add a large sphere or box collision component to that actor
• when the third person player walks inside of that collider, the behavior will trigger (For "ProximityFollow", the object will drift toward you. For "ProximitySpin, the object will spin to random positions at set intervals, spinning faster while you're farther away from it and slower when you're close to it)

The most obvious solution that I can see to this would be to find a way to exclude the position-setting behavior of "MoveComponentTo", which I'm using in ProximitySpin to set the rotation over time, yet don't actually need the translation part and am forced to utilize it. I suspect that involves recreating all the behavior of MoveComponentTo with a large series of nodes, excluding the Target Relative Location behavior. But if there's a simpler way to just exclude that pin, I'm all ears. Otherwise, I'm really just interested from a theoretical standpoint how I could have two scripts setting the position and get them to coexist, like I thought I could achieve by attaching one to the parent and one to the child, but with which I haven't found success.

[tawdry surge]

Rather than using "move to" I'd use interp nodes and then you can set rotation and location separately

[white elbow]

how do I set maximum force that a physics handle can apply?

[west sky]

That's what I figured, though I'd also want to recreate the nice Ease In / Ease Out functions of Move To. But say that, theoretically, I did have two separate BP scripts that I wanted to set translation with. Like, imagine one causes an object to oscillate back and forth locally and the other causes it to rise up and down. Ignoring the fact that's a strange thing to want to accomplish, is there a way one might have them operate in tandem?

[real notch]

Hullo! Question about collision objects as components in an object. I have capsule collisions under a SM components. I'm trying to toggle the collision on/off of all the capsule objects under the SM component. This doesn't seem to work. I do set collision (no collision) on the fire corridor. It doesn't pass it down to it's children? I can do the set collision (no collision) on each capsules... but I want to do something more efficient 😄

[cursive grove]

is there a way to expose these variables in the details panel?
I added a blueprint with editable variables as a CAC into another BP, but every time I have to open the viewport, click the body and go to 'default' and change it. But it is also buggy and messes with the rest

[spark steppe]

no, it's not possible

[tawdry surge]

They are already in the details panel in the level.
By default you are looking at the class details.. Go up slightly to the component section and select the component you want to mess with.

[stable fossil]

Is there a way to trigger this function when the variable "In Field of View" is changed?

like some sort of event that detects if a variable is changed

[tawdry surge]

@west sky yes, you'd essentially have to have one set the local/relative X location and the other set the Z
They won't overwrite each other because they are each only handling one axis

[cursive grove]

Ugh why is this so difficult,, nothing in ue4 works with logic 😭
now trying to make a list for socket names, does not seem to work with enumerate

[tawdry surge]

Why not just use an array of names?
One is actually already provided if you call "get all socket names"

[cursive grove]

Yea but still I want to be able to choose

[tawdry surge]

So make a select node and feed in your choice

[spark steppe]

no, you would want to create a setter method for that

like, SetFOV(float Value), which then sets your variable, and does everything else that's necessary

[stable fossil]

The variable is changed in the editor during play

[lucid ingot]

can some one help me with this and tell me why this is not working? Its weapon sway. I added them in for the pitch and yaw.

[prime stump]

Hi, i have this timeline that has a 30 second float track on it which goes from 0 to 1, i'm trying to make it so that it smoothly increases the current cloud coverage up to 10, but over the 30 second period so it only hits 10 when its at 30 seconds? right now it hits 10 at 10-11 seconds into the timeline, anyone know how i can make it work?

[worthy tendon]

Lerp A is increasing. So when cloud coverage reaches 5, you are lerping between 5 and 10 with alpha as 0.5 gives you 7.5

Lerp A node should be constant. In this case 0.

[prime stump]

That makes sense, but my problem there is that it sets the cloud coverage variable to 0, i need it to keep the current cloud coverage (which is set to 4 at the moment) and increase it up to 10 over the 30 seconds

[worthy tendon]

I would connect exexution pin to "Play" instead of Play from Start

@prime stump try this.

you set the position of timeline based on current cloud coverage. in your case, cloud coverage is 4, then 4/10 = 0.4 and since duration is 30 seconds, 0.4*30 = 12 so the timeline would start from 12 seconds and it wouldn't start from 0.

note that this only works as long as Cloud Coverage is between 0 and 10.

and notice dont connect to PlayFromStart because that would reset playback position to 0.

[crimson jolt]

Is it possible to save the edits made to a variable during an editor play session? For example, let's say I hit play and some changes are made to an array variable in a blueprint. When I exit the session these changes are lost, is it possible to not have the array reset? In other words, to edit the default value

[worthy tendon]

Right click on actor, then

[crimson jolt]

Hm it doesn't show up under Play From Here, any idea why? Also is it possible to only keep changes for a specific variable? Seems kinda dangerous otherwise, could screw lots of variables up

Nvm, I found it! Need to be playing while selecting the actor

But the other question still stands

[worthy tendon]

I dont think There is an option to keep specific variables. but you can copy properties manually which is of course not always easy.

[crimson jolt]

Hm well fortunately in this case, I can unplug all functionality and just edit the array since it doesn't depend on anything else

[worthy tendon]

keep in mind, all actors are copied from editor world to PIE world, so most variables would be same, just be careful about variables that change including actor transform.

[crimson jolt]

Alright, thanks!

[naive stag]

How can I get a ref to third person character in a random bp?

[elfin wolf]

you probably want to use the "get player character" node

[naive stag]

tried, didnt work

actually

i can cast after it

so ye that will work

it worked, thank you

[slim wave]

Hello there !
I'm trying to make a 2D grid with loop in blueprint but i need it one frame at a time
So i made a ForLoop but with a Delay inside
The problem is that i only have the first raw on X and the last on Y, i don't get all the "slot" of the grid like i have with a simple ForLoop
I don't know if it's even possible but i know you can multi-thread it in cpp but don't know how in BP
It's for a minecraft like generation, for generation the chunk
My code work perfectly to do that, but it's all in one frame and i need it one frame at a time for each chunk
Thanks !

What i have with ForLoop :

What i have with ForLoopWithDelay

My ForLoopWithDelay

And how i use it

If someone can save me, it would be super great 😅

(please tag me if you have a answer or if something is not clear)

[worthy tendon]

delay doesn't give you multi threading though, once delay expires, it continues on the game thread.

[spark robin]

Can I add getter/setters to existing variables?

[slim wave]

I just want to make 1 chuck per frame, not searching to do a real multi thread and everything

[worthy tendon]

you can add get/set functions but you can't change existing variables get/set behavior.

[worthy tendon]

if you want to do it per frame, do it in Tick event. it runs exactly once per frame. you can have a counter that increments every tick. and use that counter to get X,Y index for your grid.

[spark robin]

Can I then replace all get/set nodes of that particular variable with a function?

[tawdry surge]

@slim wave any reason you don't forget the for loop and just run it on tick?
That way each frame you can increment the current chunk and once you hit the end either stop or go back to 0

[slim wave]

I am in the tick with the ForLoop, but i make all the loop iteration in one frame

[tawdry surge]

Thats how for loops generally work

[worthy tendon]

what's the delay for?

[tawdry surge]

Instead of that just make the tick do the looping

[slim wave]

Yeah that's why i wanted a 1 frame delay between loopbody

[spark robin]

use the sleep node to delay until next frame, set the sleep duration to lowest possible Edit: oh wait its called "Delay"

[slim wave]

I see the idea but don't know how to make it so it's a square around a certain area like i have right now

[worthy tendon]

you don't need delay at all. or i am confused

[tawdry surge]

It's identical logic, just instead of a for loop, increment the current index in your chunk list.
Each frame will then only generate one

[spark robin]

This would print hello indefinetely. You could hook it up to begin play

[slim wave]

🤔
That's my code without any delay

it generate me a 3x3 chunk around the player

I see how i can generate 1 chunk under the player in the tick, but not a 3x3

[bronze quiver]

@tawdry surge

[tawdry surge]

That's overly complicated for generating a grid but leaving that alone.
Just delete the for loops and make a current index variable.
Increment it at the end.

[worthy tendon]

if you have access to c++ there is a way to add get/set function without need to change anything in blueprint. but if you are in blueprint only, then you have to search for that variable (use FindAll tool) and replace them with get/set functions.

[spark robin]

What would that look like?

[slim wave]

i don't see how to do it without loop and don't know how and where to use a index variable for the tick

[tawdry surge]

One minute
I have a similar BP i can share

[worthy tendon]

there is BlueprintSetter and BlueprintGetter keywords for UPROPERTY. oh and the variable you are trying to fix should be also in c++. @spark robin

[dusky crane]

if i get class and check if its equal to a parent class, does it return true?

[spark robin]

I see, so what file do I open to add those keywords/macros?

Im working in a C++ project already

[worthy tendon]

no

[dusky crane]

alright, thanks!

[exotic current]

hey hey i have a question i need to get data from a object to an task can anybody help

[runic parrot]

Has anyone have luck on using rigify for ue5 base rig?

[spark robin]

I had a pretty decent experience using Mixamo (and the mixamo rig, not using the default UE rig)

[worthy tendon]

this video seems to explain (i haven't watched)
https://www.youtube.com/watch?v=VMQ_Yw5uM5I

[spark robin]

He is using the C++ class as parent there though

Its a little bit annoying that I cant sort of just replace all instances of a node with another :l In text based programming its quite easy in comparison 😛

[worthy tendon]

if parent class is not c++ you can't do that. you have to fix manually.

[worthy tendon]

there is a tool in ue5 to replace functions with functions, or variables with other variables. but there is no tool to replace a variable with get/set functions.

[tawdry surge]

This is mine with a for loop because mine I want to happen in one frame

this is an on tick version

[slim wave]

I gonna try this

Number of Tiles = x number on X and Y, right ?

[runic parrot]

i'm thinking on just going for that, but i don't want to loose all the default settings from ue5 : (

In your experience, how much took you to replicate the default mannequin functions?

[tawdry surge]

@slim wave yeah its my total number

[slim wave]

Got it to work, but it make me random size on one axe

[tawdry surge]

This is for a chess board, so mine is 64

[slim wave]

Like here, just 2 on X

[tawdry surge]

It's pry an issue with the end of the code where its picking if it should change rows

Are you doing >= or just >

[slim wave]

Same as you <

[tawdry surge]

Set y length to 4 or add an =

[slim wave]

This should work in logic, no ? 🤔

For exemple, RenderDistance is at 6, so i should have a 6x6 square

[urban relic]

Hi, I am trying to improve the jump mechanic for my little pawn. I am using a pawn instead of a character because the 'player' is a ball that rolls around. I'm hoping to improve my 'check jump valid' method, but not sure what the best approach would be. Is there a better way to check if a pawn is jumping other than the component velocity?

[tawdry surge]

No you'd get 11 tiles

Or 12

[slim wave]

🤔

[tawdry surge]

You'd need 36 to get a 6×6

[mental trellis]

Not 36 then?

😄

[slim wave]

Well, i have a 7x12 square

[feral ice]

How do I use the outer cone in the spotlight as a trigger box so if any object is inside of the outer cone it will make the object red

[slim wave]

Ok my bad founded

Multiply by himself

not x2

i'm dumb

sorry

[tawdry surge]

Haha np
Was just confused how you got 7x12

[slim wave]

Math 🙃

[tawdry surge]

If you don't need it to keep generating anything after it's done with the square you can call disable tick to make it stop

Or move it to a timer by event or function

[slim wave]

Well, after that i need to generate in continue around the player ^^

like i did with the loop

[tawdry surge]

Ah ok

[slim wave]

This lovely math

Thanks a lot, you unlocked me ^^

[tawdry surge]

Np

[molten roost]

im working on my first game with my friends and i need to rotate my particles with player's rotation, this is what i have so far, but it doesnt rotate:

[high fractal]

Lmao @ Piss

[tawdry surge]

you mean set it's initial rotation or actually follow the player

[molten roost]

follow the player

[molten roost]

dont ask 💀

[jolly sentinel]

Hi, is it possible to create a character/Avatar customisation system using the Ready Player Me SDK buy doing the image upload within Unreal Engine?

[onyx frigate]

Hello guys, I am using Physics to move my pawn and I have an issue:
the pawn flips when Pitch hits a certain value. I have set bUseControllerRotationPitch = false.
Any idea ?

I would to limit the rotation up to the point where it might flip (to avoid flipping)

clamp rotation on tick ?

[sacred elm]

Is there any reason a newly created player controller would not be able to move? I’ve got physics turned on and it’s also got it’s collisions set

Also I think clamping it might help

[zealous moth]

Well physics is 1 thing and controller rotation is another. So if you use physics, it will do the physics thing.
If your pawn has a physics asset, you can increase the dampening to prevent or at least pseudo lock the rotating

[zealous moth]

in game or after you start?

[onyx frigate]

it's just that I noticed that If I leave this setting on the controller the applyforce/impulse doesn't work

I do have some dampening but I want to keep it at its value. Dampening is not an option in my case

[zealous moth]

why the controller? you should do that on a pawn or something

[onyx frigate]

I do that on root component of the pawn that is physics enabled

but applyforce is done in the controller though, on the component

[sacred elm]

Like when I press start, it will be affected by physics, but not the inputs

[onyx frigate]

and that's why I have to change those settings to make it work

[zealous moth]

show a pic

both of you

of your setup

[onyx frigate]

sir yes sir

[zealous moth]

you use terms a bit incorrectly so I am confused as to what you are doing

[sacred elm]

It might take a little bit because I’m not at the computer

Sorry

[onyx frigate]

no worries, thanks !

Lookup function (bUsePhysicsMovements = true), Pawn hierarchy: PhysicsComponentToUse = CollisionComponent / Settings for controller in code (yes, that's on the pawn, sorry)

last screenshot didn't work

[dusky crane]

is it okay if i run an interface 20 times per second?

it retrieves all gameplaytags on a given actor

[onyx frigate]

make sense boss ?

also, for some reason applying the force on the collision component rotates everything under it, but not the actor himself

the rotation of the pawn is always 0 while rotation of the collision component is changing

not sure if that's a bug, a mistake from me, or something else

[sacred elm]

so I'm just trying to use the capsule's forward vector to affect the movement input

but even when I fully replicate the third person template, it won't move

this is the capsule's details panel

@zealous moth

[brazen leaf]

Are there blueprint nodes for calling out to an API and returning the response?

[mental trellis]

Calling out how?

[brazen leaf]

Is that a plugin? (it is https://www.unrealengine.com/marketplace/en-US/product/varest-plugin?sessionInvalidated=true)

[zealous moth]

I would bring it up in the #cpp channel since I am not sure what the repercussions would be of hardcoding it that way.

[onyx frigate]

Well it's the same as doing in a BP

[warm terrace]

Does anyone know how to toggle visibility of a static mesh in a array using collision. I have a array of static mesh cubes and a animated cube that collides through them. Id like to toggle the visibility of only the mesh in the array that the animated cube come into contact with.

[onyx frigate]

Just that I do nothing in BP except tests mostly

Is the pawn supposed to flip ? Because it doesn't feel normal at all :p

I read using the controller fix the issue but with forces ... Not sure

[neon spear]

Is it bad practice to have something like this on the event tick

since it constantly is checking

I can also put it on the end of anything that deals damage so it only checks when player health is changed

but then this big chunk is gonna have to be copy pasted a million times into a bunch of different things

so which is worse for performance? Having it on event tick or having it run this health check everytime player health is changed by something (something being like a bullet making collision with me or i use an ability that does self inflicting damage)

[warm terrace]

or if this has been asked before point me to the thread. I checked but the way Ive seen using on begin overlap I cant get to work with a array

[neon spear]

Put it there as in at the end of everything that deals damage? And I can’t make it a function cause functions can’t have delays

[onyx frigate]

Hey, you could have a collision sphere / cube with overlap, and get the list of the actors, then apply the sethidden setting

[warm terrace]

I tried that maybe I didnt set it up right

[onyx frigate]

onoverlapbegin and end would be your triggers to hide / set visible

probably

both colliding elements must be at overlap

if one is iignore, nothing will happen at all

[warm terrace]

I can do this to a single static mesh but its doesn't seem to work with array. Even if I get all children component of the array it just turns them all off. Also I cant set collision for array like I see people do for this set up

I'm still learning but is something like this requiring a construction scripts?

[teal talon]

Question: I have Point A and I need point B to move to point A a little at a time. Not using pathing. What does the math/blueprint look like for this?

[onyx frigate]

Have the cubes as separate child actors

[warm terrace]

get world location from point A and use move component

[onyx frigate]

Then you'll have access to all actors stuff

[bronze quiver]

If a blueprint is executing will you always see the connectors fire off? When you simulate

[warm terrace]

@onyx frigate they are separate child actors

[teal talon]

but it ask me where to move it to, I don't want to tp to the A, I want to move 1 step closer, then another step closer the next second/click, what is the math on having 3 cords at a, and 3 cords at b, how do I get the locations between them to move to. How do I deal with negitive cords too. So I'm -100 on z. Vs z 100

[tawdry surge]

@bronze quiver No.
Generally the debug object isn't set.
As long as it is tho, it will

[warm terrace]

@teal talon You could get world location from each point and use a distance 3d to get the exact distance

[teal talon]

thank you, I didn't see that in the options.

[warm terrace]

@onyx frigate

this does not recognize the individual mesh of the array. And if I try to add a index or set visibility before collision happens it breaks

[pale flare]

im trying to just move the camera up/down and not the entire character but i need to clamp how far up and down

[tawdry surge]

You need a for each loop to iterate over the whole array

[pale flare]

right now the camera can do a full 360 lol

[warm terrace]

@tawdry surge a for each breaks it

[pale flare]

wdym

[warm terrace]

if I place a for loop between get children comp and toggle vis nothing happens

but I remove the toggle works but just for all

[pale flare]

i think you @'d the wrong person but lemme look lol

[warm terrace]

I did my bad

[pale flare]

@warm terrace do for each in array

[unique turret]

Hey guys, simple question: is it bad to place a loop within a loop?

[tawdry surge]

In BP, yes

[unique turret]

Hmmm, okay, so how should I be implementing something like this? (This is an event begin play, where I'm checking if the light (self) is connected to a light switch - and if it is, to match its on/off state:

(the first loop is getting all light switch actors, the second loop is running the array of lights attached to the switch).

[wraith cave]

Guys I wanna make blueprint node that helps me move my character forward without physics

I am currently using this do you guys have any better idea

[wraith cave]

and also how can i increase my float variable over time? I wanna make like an endless runner and the speed increases over time

[pale flare]

should inputs be in the player controller or the character

[wraith cave]

player controller

[pale flare]

understood :)

[wraith cave]

Oh wait i thought you asking about mine nvm

lemme see yours

[sacred elm]

wait, did anyone actually answer my question? Sorry if I missed it

[pale flare]

im just trying to get my camera to move and not the character

so im tryin to figure out where to put my inputs

[tawdry surge]

@unique turret I'd make an event in the light switch actor that sets the visibility on all of it's lights.

@pale flare is use control yaw turned off?

[wraith cave]

Lemme send you a screenshot from my old project

[pale flare]

its turned on

[tawdry surge]

Turn it off

[pale flare]

thank you

i think its workin

anyway to change where the player controller camera spawns

[dusk dust]

Hello friends

I would appreciate an answer

has anyone sample a render target on a procedural mesh grid? if so, how?

[onyx frigate]

Use other actor from overlap

Not your array. You want the one overlapping

[tawdry surge]

@pale flare if you have a camera component attached to a spring arm in your character, you controller will automatically set your view target to that one

[pale flare]

basically if i attach a camera i can no longer look up or down

if there is no camera everything is perfect but my view is in the com

im sure its probably a simple fix but im struggling lol

[tawdry surge]

Did you do the up and down movement logic?

[flat coral]

Is there a good reason I can't reparent an object to an actor?

[pale flare]

just the basic stuff

i tried just rotating the camera

[tawdry surge]

Yeah.. that should work

[pale flare]

which worked but my camera could do a 360

lol

id prefer not to be able to look behind me like a horror movie

[tawdry surge]

You can use the camera manager class to limit that

It's assigned in the controller's details panel

[pale flare]

gotcha and the camera will inherit that?

[pale flare]

i did this but the camera still does a 360

[tawdry surge]

Add control pitch

Not relative rotation

[pale flare]

that can only reference self not that camera

[pale flare]

so when i do that the camera cant go up or down at all

[tawdry surge]

The camera component should be using control pitch and yaw in its details panel

[neon spear]

how do i have an event constantly checking if i am less than 1 hp

[mental trellis]

Why not have a setter functions that checks if you're less than 1 hp?

[neon spear]

im still learning so to me as far as im aware i dont know how to have the game know i fell below 1hp without it being a tick or checking after every time i take damage

since its something that needs to be checked constantly

[broken wadi]

Are you using Event Any Damage?

[mental trellis]

Surely it only needs to be checked when hp changes ?

[tawdry surge]

@pale flare use pawn control rotation

[pale flare]

when you take damage make it check your health

[pale flare]

oki ill try

[neon spear]

have that now. Wanted to make sure im having it all setup efficiently as to not waste resources or make it more intensive

[neon spear]

thats what i have now

ill resend the image

[broken wadi]

On your Event Any Damage you can check the current health to see if it’s equal to 1hp.

[pale flare]

i believe that worked

[neon spear]

https://media.discordapp.net/attachments/221798862938046464/983472757025165362/unknown.png

i use variables not the damage nodes

i should mess around with that maybe

[broken wadi]

Use Apply Damage and Event Any Damage

[neon spear]

so event any damage will trigger anytime any damage is dealth with the apply damage node?

[pale flare]

yeah try to have as little as possible on event tick

[neon spear]

and then the any damage can run a check on if im less than 1 hp

?

[mental trellis]

It's not a problem having things on tick. It's a problem of having a lot of things on tick.

[broken wadi]

Yea basically

[neon spear]

yea i havent tried that but ill look into that

this all just kinda makes sense to me what i have now

trying to take it one step at a time

but ill try and learn those events

thanks guys

[broken wadi]

You can also add health by using negative damage for like a medpack item

[pale flare]

here is a very simple way to do it

[haughty egret]

Anyone know a way to easily clear the localization cache? Seems we're getting some weird BS happening with old text caching.

[broken wadi]

There’s also other useful nodes like Apply Radial Damage for an easy to setup area of effect. @neon spear

[pale flare]

^

[neon spear]

Alright I gotta upgrade my damage blueprints then

thank you!

[pale flare]

👍

[neon spear]

so im insta dying

[sharp sigil]

How come I can't find a for loop node in BP lol

[neon spear]

the value on jump recoil is 10

and it does 100

do i have the lines messed up

[pale flare]

show me what is to the left

[sharp sigil]

Seems to only happen on widgets

[pale flare]

chances are it is triggering multiple times

[pale flare]

so the reason could be that you are setting your health to the "explosive jump recoil"

after apply damage remove set cur hp

[neon spear]

this apply damage box

doesnt even know what my hp is

right?

should i attached my current hp to the damaged actor circle?

[pale flare]

so basically the apply damage sends a message to the actor saying hey here is some damage

[neon spear]

well the actor technically doesnt have health

[pale flare]

and your actor has the node "event any damage" and it spews out the number

[neon spear]

i think the problem is then

[pale flare]

all it is, is a message basically

[tawdry surge]

tater is right. you are setting current hp to the damage amount

[neon spear]

this is also what i have

[neon spear]

okay ill try and fidget that

[pale flare]

if you look at this, you first have to subtract the damage from your health

[neon spear]

yea i did that but i think i mustve missed an earlier earlier step

cause how is the event supposed to know what my health is

all i have is a variable called health

that isnt connected to the apply damage thing

[pale flare]

make sure your health variable's default value is 100

[faint pasture]

Your health is the health variable. What's the problem?

When you take damage, set health to be equal to health minus damage, then check if you're dead.

[neon spear]

okokokok that was my first time using that

i got it all now working

i didnt know at first that this was what told the game what my health was

i didnt have that setup right

thank you thank you all

[faint pasture]

@neon spearYou can just give your variables readable names. CurrentHealth is better, a year from now you might be scratching your head trying to read some of your variable names.

[neon spear]

event any damage and apply damage are all connected without actually being in a line and when any damage is detected from apply damage it is to subtract that damage value from your current hp and apply it to your current hp

thats what i didnt get

at first

[neon spear]

youre right i was following guides but i should just do a neat consistent way to understand it all

even if the text is slightly longer

[faint pasture]

Hence my name. They're ok for when you have no clue what you're looking at, but as soon as you can, try to do something tiny on your own. You'll learn 100x faster.

[neon spear]

i learnt basic hud stuff

some doors and collision overlap

delays

emitters player lcoation sound stuff variable stuff

im trying to make a mini game with what i know

and make stuff i dont know how to yet

thanks for the advice

[dusk dust]

Hello friends
I would appreciate an answer
has anyone sampled a render target on a procedural mesh grid in blueprints? if so, how?

[faint pasture]

If it's possible, it's super duper hard and C++ territory for sure. How big of a render target are you talking, and how often is it changing?

wait

[dusk dust]

it will be changing pretty often i think, right now its 512x512

its a heightmap

[faint pasture]

are you talking about using the render target data for CPU stuff, or just sampling the render target in a material ON the mesh?

[dusk dust]

i want to loop through the vertices on my procedural mesh and offset them based on the height values in the render target, no materials involved

[faint pasture]

There's a GetPixelColor node, good luck, it'll be slow.

[dusk dust]

oof

[faint pasture]

If you figure out how to get the render target data back on to the CPU for gameplay purposes in a simple and fast way, let me know. I started out thinking about doing that for my field of view mechanic but am now going in a different direction.

[dusk dust]

sure ill let you know

[faint pasture]

@dusk dustFrom all my research and dev on it, GPU -> CPU for gameplay is a non-starter. You'll need to get deep into the weeds in C++ to get it even somewhat performant I think.

[dusk dust]

ah man

its just crazy how this isnt a well implemented feature

[faint pasture]

I'm not aware of an engine where it is. Old article but this can get you thinking about the approach.

[runic parrot]

Hi! does anyone know if there's a way to run some event/method when game instance starts?
I want to populate some variables on the game instance, like "Player settings".
I can populate them when the controller of the main menu starts, but it makes more sense to let the GI handle that

[teal talon]

Thank you, that worked really well. Lots more to do, but you rock solved a frustrating issue.

[flat coral]

BTW Do BPs have streams yet?

Like iterable streaming

[blissful gull]

how do you async load a streaming level in BP?

i tried this:

and it doesnt make it visible after loading

oh wait nvm i see what's going wrong

[drowsy rapids]

Hello BP gurus, how does one get a blueprint editor utility actor to tick / update in the editor realtime?

I've tried the timer with a call in editor function but the official docs say that BP utility actors don't allow call in editor 😩

[icy dragon]

Isn't Editor Utility BP always run once?

https://docs.unrealengine.com/4.27/en-US/ProductionPipelines/ScriptingAndAutomation/Blueprints/

[twin shale]

Hey, I have a hopefully quick question. I have an AI with a Widget Component. In the AI I am specifically setting rotation on owning client to face the player camera. The component is not replicating, however, the rotation is still replicating to all clients. How do I stop the Widget Component from replicating its rotation to all players?

[dark crow]

https://chriszuko.com/ue4-how-to-editor-tick/

But this requires cpp, if you are comfortable with it, it's basically a solution

[thin panther]

#umg

[drowsy rapids]

Ooh awesome!! Thank you so much!!

[tepid shore]

Is this an error that'll hurt me? I don't want any, but whenever i use this function on nothing it returns this error?

Nothing breaks with this error

[foggy escarp]

its nice to avoid any errors even if to make it easier to debug later on.

You could do a check for valid.

[tepid shore]

ope yup

I added another branch for the return value on the line trace so it doesn't execute no matter

whoops

[warm bane]

Ey, when i spawn my character, it just falls over 😂

[undone surge]

is it better to create widget designs custom in photoshop or something including text and then just use them on buttons in widgets or use designs from UE itself. For like simple texts like lists of items what is more common ?

[surreal peak]

You usually design the icons and borders outside UE as textures, but use everything else from UE

Specifically since UMG is meant to be used with lots of custom widgets that can be reused by exposing parameters. E.g. a button with a text that has the text exposed

[undone surge]

i see

what about fonds

fonts

[surreal peak]

You import them

[undone surge]

like i have to import fonts so is it just better to design the enter UI outside UE and then just put invisible buttons over it ? @surreal peak

[surreal peak]

Despite the graphic part of the UI, stuff should be inside ue

Text and fonts specifically so you can properly localize the text and ensure your font actually supports all the different languages

Again the only stuff you'd design outside is maybe a mockup and then the actual graphics. But everything else is usually ue

[undone surge]

alright thank you

[barren relic]

If I have an fps and I want to have a line trace in the direction of the players input rather than the character's forward vector, is that possible to do?

I might sleep soon so if you have some info for me let me know

[surreal peak]

Depends on what your goal is, but to answer the question directly: Acceleration on the CharacterMovementComponent can be normalized, which results in the InputDirection.

[barren relic]

thank you, i'll try that and see if it works in the morning

[barren relic]

something like this then?

not sure where the end is supposed to be, I need it to be a certain distance from the the player in the direction they're holding.

[surreal peak]

Yeah that should work. Not sure if the acceleration is sort of invalid if you deactivate the CMC or stuff like that, but I would start with this.

[barren relic]

im going to add some fixes and see if it fires correctly

[surreal peak]

That's always the same boring math.
Start = GetActorLocation
End = GetActorLocation + (Direction * Length)

Length being some float or double variable fwiw

[barren relic]

does my math look right

[surreal peak]

Yes

45 is a bit short, but yes

You can simply use the debug draw mode on the line trace node to make sure you are doing it correctly

[barren relic]

right of course

Line trace is firing as intended, thank you

[golden garnet]

How do I set the rotation of a 3rd person camera to a given rotator? I'm working with UE5. The internet says that UE4 has a specific command, (something like "set control rotation,") but no such command seems to exist for UE5

Context: I'm trying to get a 3rd person camera to rotate around the character so it always keeps the player between it and a set point.

[grave apex]

I have an actor component that implements an interface, and Im trying to send it a message via this, but it's not triggering

(this is in an actor component)

is there some secret I need to send interface messages to actor components?

it seems like the first set of nodes should realize the actor implements the interface via the actor component

[golden garnet]

(Set Controller Yaw Input doesn't work for what I'm doing, I tried deriving an amount I need to rotate the camera by and plugging it in, but it multiplies the input by some odd amount that I can't seem to access in the math)

(Camera booms don't rotate, apparently, and rotating the camera just rotates the camera around its own, personal axis, obviously, and attaching the camera boom to an added component like a cube doesn't do anything... I can rotate the cube, but the camera and boom don't rotate with it.)

(This seems like it should have a REALLY obvious way to do what I'm trying to do... all I'm doing is trying to reorient the camera. But nothing seems to work.)

[silver finch]

Hi all!
I have an instanced material with some exposed parameters.
I want to be able to change the values of said parameters at runtime.
So far i've managed to change the color with an keyboard input but i want to complicate things a bit.
I want to have 4 keys for each parameter so when i press one of them i will then be able to change that value with + - buttons for example.
So it should be something like.. if key 1 is pressed enable control of param 1 with + -, if key 2 is pressed enable control of param 2 with + - and so on..
This is my first unreal project and this sounds like a fairly simple thing to do but i'm unable to find a suitable tutorial : (

[atomic solstice]

Can someone help explain why this BP keeps screenshotting an extra random photo?
i.e. I have 3 cameras but end up with 4 screenshots.

Guessing it's because this actor variable doesn't have a default value of my first camera but I can't seem to change this default value. It just stays as "None"

[golden garnet]

Just tried to grab the controller for player 0 to try to rotate that aaaaaand it killed Unreal engine dead. (Something about a render error.) Which also took discord down with it so now I'm on my phone waiting for discord to open. I am frustrated and hungry and am going to go eat.

No idea why something as basic as rotating the players camera around the player is so unintuitive. I've tried everything ----
I've tried the command add controller input yaw (or something like that,) but I can't figure out the math for how to get it to move to a specific angle, (presumably you would add the difference between the float value of the current rotation and the desired rotation, but add controller input yaw multiplies whatever float you add in by some number I can't find anywhere.)
I've tried rotating the camera boom, but I guess they dont rotate. (Rotating them in the component viewer does nothing to anything else. Apparently all the boom does is change the cameras location to keep it from intersecting things.) I've tried moving the camera manually, but the camera does weird stuff as the pawn itself rotates.
I thought about removing the camera from the player and making a new pawn for it that follows them, and I might still resort to that, but it looks like a nightmare of it's own, (I'll need to figure out how to make a pawn spawn another pawn, would should hypothetically be easy, but while I havent looked it up online l---- I got distracted by my new idea for a way to rotate the camera --- I couldn't find a relevant command on my own.)
I've managed to rotate the camera around it's own axis, and move it around, but its motion is bumped around and the pawn's movement, naturally, so that's a no go, unless I want to somehow adjust for that, but that seems like itd be very inefficient and clunky...

So I'm about at my wit's end.

Sorry for big paragraph

[undone surge]

if i have an actor like a widget in which i want to make some variable is there a way i can keep track of the variable if the widget gets destroyed

[cosmic kelp]

Store it in a variable in another blueprint. Such as Game Instance or possibly game level. Depends on what you might be doing.

[undone surge]

alright

[cosmic kelp]

For example, I have a volume setting that I need to remember from a Main Menu. The player may go press pause while playing and decide they want to change that volume on that pause menu. So I have a variable that stores the volume level setting in the Game Instance.

[undone surge]

i see

thnx

[tawdry surge]

@golden garnet just outta curiosity has anyone suggested you take a look at this?
https://dev.epicgames.com/community/learning/courses/kry/build-a-third-person-character-from-scratch/mDv/build-a-third-person-character-from-scratch-introduction

[golden garnet]

No, but I'll take a look. Sorry for being frustrated, I was feeling hangry.

[undone surge]

@cosmic kelp i made a separate bp. how do i reference the variables from that? do i cast or just create a variable of that bp

[mental trellis]

Either one will require an instance/object of that other bp

It won't just get it from thin air.

[undone surge]

i referenced it by creating and obj variable of that bp but its not storing the updated data of the variable

[next zodiac]

Hello. Sorry to bother, I've been looking around for this for quite a while now and I haven't been able to find exactly what I'm looking for, so I figure i'd rather ask more experienced people who have certainly come across this situation.
I'm studying the Blueprint method in Unreal and I decided to give it a try and create my first prototype. However, for the kind of game I want to build I will need to create arrays/data tables similar to the one on this image.
This can be commonly found on .dat files as well, where tables of data are structured like this. However, after looking at blueprints, I noticed it's impossible to layout an array like this.

I've also looked at Data Tables and Structs, but apparently theres nothing like this, or perhaps I've been looking on the wrong place. What BP would I have to use to lay out a structure like this?

[mental trellis]

Create a struct that defines a row.

Create an array or data table that defines the table.

How did the array/struct combination not do what you want?

[next zodiac]

I haven't gone to the combination yet. But in C# for example, I can create that array directly, as you can see in the image. So i was looking for a direct counterpart in Unreal Blueprints. I noticed that by creating an array you'd only get 2 colums: ID and whatever variable you set.

Maps only allow for 2 columns, as well as data tables, so I was wondering what i was missing, or if this is was a limitation

I'll certainly give the combination a go 😄

[barren flower]

@next zodiac you are talking about an array of structs

if you want to do this in blueprint, create a struct with those headers, and just make an array of them

[next zodiac]

this Item_Data is also an enum

thank you @mental trellis and @barren flower

I'll looking into the structs + array combination 🙂

[barren flower]

https://d3kjluh73b9h9o.cloudfront.net/optimized/4X/7/2/e/72ef6350307134b79b68fafdc173851617ba0775_2_690x226.jpeg

This is what you want

Okay gang, now I have a question. I'm importing over a thousand meshes, and its slow as heck, like 14% over 3 hours

Each mesh has a ton of materials I think is the problem

is there a way to batch import this stuff, rather than relying on unreals importer, which seems painfully slow

[mental trellis]

For static data like that, you really do want to use a data table, though.

[tawdry surge]

There's probably a plug in but it won't be free

[jovial lagoon]

guys I have a Map (dictionary) and I would like to sort it by the values... how can I do that?

[barren flower]

Im not sure if this is part of the extended library plugin or vanilla

but you can can drag off and get just the values, and then plug that into a sort node

If you are talking about like, actually re-ordering the map, the point of them is that they are unordered and thus extremely fast to access

You would in that case need to create another temporary map and do your own sorting algo. Loop through and find the smallest, then add that to the new map then the next, then the next, and keep looping till its sorted

[jovial lagoon]

ok

[lapis flower]

any idea how i can get this to work?

[jovial lagoon]

the point is that after that I need to loop through them and I need to have them in order

[mental trellis]

Tmaps aren't great for that.

Is there a reason you're using a map over an array?

[jovial lagoon]

I have to save the player and his time in it

[loud sky]

Hi, how can I transform an actors movement so that it only moves along one local axis of another actor? Like it is tied to the local rail of an actor but can still move freely along it?

[mental trellis]

If it's a small map, it really makes no difference how you do it.

[vast crow]

Can't disable collision for HISM

• I disabled it in code

HISMMeshComponent->bDisableCollision = true;
HISMMeshComponent->SetCollisionEnabled(ECollisionEnabled::NoCollision);

• I removed everything related to collision in the asset

What's going on?

[jovial lagoon]

what do you mean?

[elfin wolf]

try "get owning actor"

instead of get pawn owner

[mental trellis]

Just grab the values from the map, sort them and loop through that.

Or create an array of structs based on the map, sort that array and look through it.

How many entries are you going to have in this map?

[jovial lagoon]

I am asking how to sort them

[mental trellis]

Do arrays not have a sort function?

[jovial lagoon]

may vary

[jovial lagoon]

no idea

[mental trellis]

Oh well.

#cpp

[tawdry surge]

There's a plug in for a BP array helper library

Includes sorting

[jovial lagoon]

-.-

[tawdry surge]

Should be free last I checked

[elfin wolf]

https://www.unrealengine.com/marketplace/en-US/product/array-helper-bp-library

who knows why its not included

[paper galleon]

Most people do such in cpp

[mental trellis]

PredicateSort in BP. Neat.

[tawdry surge]

Pry cuz container sorting should be in cpp

[mental trellis]

Vary from what to what? 1 to a bajillion?

1 to 4?

[paper galleon]

It can get quite expensive so not much point to doing it in bp

[jovial lagoon]

1 to 5

why does that a change?

[mental trellis]

So sorting that array, even with the worst sorting algorithm in the world, is not going to be expensive.

Get that plugin ^

[jovial lagoon]

yeah ok, so I'll need to make my sorting algorithem

[mental trellis]

However

Do you need to maintain the key->value relationships with the sort?

[paper galleon]

You can just get the plugin too

[mental trellis]

E.g. player 1 has time 50m, player2 has time 40m, player3 has time 5m

etc

[jovial lagoon]

yes

[mental trellis]

Then you need to convert your map to an array of structs and then sort that.

Or you will lose your associations

Unless you sort the keys, not the values, and use the map's key/value pairing in the sorting predicate

[jovial lagoon]

I think I can use a find(?)

[tawdry surge]

Or just use a regular float array, and just assign each player an index number that corresponds to their time

[mental trellis]

E.g. Sort(A, B) { return Map[A] < Map[B] }

What will that solve, MW?

If you sort the floats, you're still going to lose the index association

[jovial lagoon]

well... if I sort the array... I'll then find the Player that has the same time

[tawdry surge]

Arrays are sorted. If player one is given index 0 then I just need that

[jovial lagoon]

and work with that

maybe(?)

[mental trellis]

Arrays are not sorted.

They can be.

[tawdry surge]

Not sorted. I meant they don't change positions

[mental trellis]

But if you sort an array of {1,5,3} you will end up with {1,3,5} and now player 2's value (5) is now wrong (3)

Either way, you need to sort the keys or an array containing both the keys and values

[tawdry surge]

You can track who owns what data with tracking the index rather than having a map and doing a bunch of work to reorder

[mental trellis]

Find will search for a specific value, not really useable for sorting

[mental trellis]

That's exactly what his map does, it maps player to value, you don't need an index with a map.

[jovial lagoon]

I know... but if I sorted the time array, I can find who had that time that way

[mental trellis]

And it would not solve his problem

That is true, @jovial lagoon

Unless 2 players have the same time.

Then instead of player 1, player 2, player 3 - you will end up with plaeyr 1, player 2, player 2

[jovial lagoon]

true

[paper galleon]

It's not that complicated use a struct and write your own sorting algorithm.

[jovial lagoon]

but unlikely

[mental trellis]

Because unlikely bugs you can foresee bug ignore are fine?

[jovial lagoon]

not saying that

I'm still fixing it

[mental trellis]

Get your array of keys (player references, I assume)

And then sort that list based on the value in the map

When you compare Player 1 and Player 2, actually compare the values in the map associated with those players

[jovial lagoon]

ok... a duble sort

interesting

[mental trellis]

No, not a double sort.

Just sorting by secondary/associated data.

[jovial lagoon]

I mean

I'll have to change the positions of the players also, using the sort of the times

[mental trellis]

You would sort the keys array (which would not change the map, the map generates an entirely new array and gives it to you when you ask for its keys)

This is why sorting tmaps is bad

[vast crow]

ok, ALL OF THAT finally disabled collision

                variation.MeshComponent->bDisableCollision = true;
                variation.MeshComponent->SetCollisionEnabled(ECollisionEnabled::NoCollision);
                variation.MeshComponent->SetGenerateOverlapEvents(false);
                variation.MeshComponent->SetCollisionObjectType(ECollisionChannel::ECC_WorldStatic);
                variation.MeshComponent->SetCollisionResponseToAllChannels(ECollisionResponse::ECR_Ignore);

Even though ->IsCollisionEnabled() still returns true, but that is fixable

I think that's enough unreal engine for today...

[jovial lagoon]

I know it is

But I didn't want to change it, so I was looking for a solution

but ok

[mental trellis]

It's cool. You have a very small map. Optimising this part and screwing over your other code is pointless.

Just go with it.

[jovial lagoon]

thanks

[oblique warren]

Hello everyone

I just recently started learning UE5 and was scrubbing through the advanced locomotion system

[untold fossil]

I have a super weird issue. In my game players can take a seat in a lander craft to go down to the planet and back to a space station. The system uses possession of pawns (seat is a pawn). When the lander craft reaches the planet surface and you leave the seat it works perfectly. But when the lander craft goes up again to the space station and I leave my seat my character is suddenly teleported a huge amount up in the Z direction. Now I've tried everything I can think of, turning off all of my code, trying different ways to have the character leave the vehicle, but every time when I reach the space station and leave my seat my character is teleported up. I suspect it has something to with the character movement component we use in our character (Unreal default). I'm thinking it may have something to do with the ground check or whatever. Does anyone know what could cause this?

[oblique warren]

I just wanna know how to create the node on the top without creating 2 nodes like on the bottom

[tawdry surge]

Right click the pin on movement model
Split struct

[oblique warren]

ah thanks

[naive stag]

How do I make AI charecter to move

I wrote a script and it works, but for some reason the character itself is just stuck to the same place and not even falling down

[mental trellis]

So how do you know it works?

[naive stag]

First of all, I got it from a tutorial because i needed basic info on how AI works
Second of all. It runs input and returns output through successfully

[icy dragon]

First of all, have you give it navigation meshes/invokers?

[naive stag]

I have no clue what that is.

You mean the target mesh it will move to?

[icy dragon]

That's the missing piece of the puzzle.
Basically them AIs use navigation meshes on the map surfaces so that they know where to go to other location.

[naive stag]

Great and how can I do that

[naive stag]

It’s still not doing anything

I have been trying to fix it

But I can’t

[naive stag]

everything that i did

is there something that im missing?

[tawdry surge]

You have a nav mesh in the level?

[naive stag]

no, idk how to add one

[tawdry surge]

Place actor panel
Nav mesh volume

[naive stag]

in bp?

or in the level

[tawdry surge]

No in the level

It has to surround anything you want the ai to be able to walk on

[naive stag]

where can i find it

[tawdry surge]

Hit p on the keyboard to show the visualization.
It's in the place actors panel.
Search nav mesh volume

[naive stag]

where do i hit p

nvm

i found it

thanks it works

how do i add animations doe?

[limber jacinth]

[dire flint]

hey guys. i have run into a snag and im not sure how to get around it. I am trying to create a bp_controller to use as a single control setup for multiple pawns (characters with different skins essentially) I currently have input controls from gamepad axis to control the movement but i cannot find a way to output anything from inside the controller to the controlled pawn. everything i have tried to put in says "target self is not a pawn" (which i know it isnt) but i cant seem to find a way to define a pawn. even dragging the pawn itself into the node editor didnt let me set it as the target. I dont want to have to create the entire control code for every pawn but im not seeing any other way around this. the closest i have found is "get owned pawn" which only targets the HUD and still requires a defined pawn.

GetControlledPawn will return the pawn the controller is controlling. Is that what you are looking for?

[dire flint]

loading it back up atm ive tried so many ways i dont remember if i tried that without looking at it

i think the getcontrolledpawn is what i ended up with in my current code without error.

which led me to realizing that the engine doesnt natively recognize gamepad inputs

ok this is what i had ended up with

movexdirection and moveydirection are the binds for the gamepad x and y axis inputs

everything else was named by the engine

i think this may already work but i havent been able to get the gamepad going to test it.

[limber jacinth]

It does not appear to be giving them a direction. Try removing GetActorLocation from movex AddMovementInput, pull from GetControlledPawn and get ActorForwardVector and plug that into the AddMovementInput. If that works, remove it from the second one, pull from pawn and GetRightVector and plug into the second one.

[dire flint]

the control is for a dual stick setup. left stick is up down left right not forward back left right. i dont need the characters orientation at this point. just its current location so that i can move its current location.

[limber jacinth]

Fair, but by passing in GetActorLocation I would think you are not telling what world direction you want it to move. You are passing in the current location and a value to move in the exact same spot you are already in. I could be wrong, I have never programmed for gamepads though.

[dire flint]

i was just seeing the same thing in it.

i got the axis to tell it how much to scale the movement but i see that it isnt telling it a world direction to move

[limber jacinth]

It might be worth a test to use ForwardVector in the top one. This is the Pawn's X direction and not necessarily forward and back.

[dire flint]

the get actor location is most likely a coordinate not a direction

ok so swap get actor location with get forward direction. brb lemme see what it does lol

[limber jacinth]

The ole "Plug stuff in until it works" method 😄

[dire flint]

well see now it wants a rotator not a pawn...

omg i think its stable...

[limber jacinth]

Did you just grab GetForwardVector? Try this one.

From the pawn

[dire flint]

oooh

good find

oh dang...

mine wont work...

im pulling the forward vector from the inputs not the actor

although finding the 'make rot from xy' is lovely. going to allow me to combine the 2 axis into one input.

[limber jacinth]

Yeah, you might have to cast it to a character. Sorry, feel like I may have confused the issue more for you.

[dire flint]

oh... i dont need the actor's vector. i need the world's north vector...

[teal nexus]

I have a BP actor with bunch of static mesh components inside of it. No code. I need to decompose this actor, so to speak, into meshes back into the level, while retaining all transforms. How do I do this ?

[dire flint]

and i dont need to define a direction if i hard code the add move to a specific value

sometimes simple wins out

this will scale the x direction based on the x axis input and same for y

i can make him move faster or slower by increasing or decreasing the x and y directions

now on to figuring out how to install this gamepad into unreal 5

thx

Im not sure how to word this on google but basically from where I spawn this will launch me diagonally to the right. With Blueprints is it possible for it to launch me to the right of where im facing as opposed to me being forced to look a certain direction in order for me to launch to the right ( i have mouse and camera locked together already) Do i add an invisible mesh to my character diagonally off of me that follows me and i can set it to launch me towards that mesh or something? If its too complicated to explain I can research it on my own I just need to know what to type in. Is this camera blueprints? ect

[thin panther]

Use get right vector

Its all possible, just needs some knowledge of vector math

[neon spear]

alright ill learn vectors next

thank you

[jovial lagoon]

done ❤️

Hey all, I have a construction script for a flickering light BP, where I’m using a Random Float in Range for two Set Scalar Parameter Value nodes - one to affect the Point Light’s Light Function and another for an emissive Material. The problem is that using the same Random Float in Range node appears to output different values for both these Scalar Parameters. How would I generate the same random number for both the Point Light’s Light Function and the Static Mesh’s emissive Material within the same Blueprint?

[brazen pike]

Could set a local variable

[zealous cedar]

Could you explain how, briefly? I’ll look into it also! Would this maintain the random per BP instance I need when placing multiples of this actor around my scene?

[brazen pike]

You right click on the output of the random float and click the option that says local variable. I honestly can't remember if you can or can't use local var in conscruction script, so if it doesn't say local variable just make it a normal variable. Works the same

then you get that variable and connect it to the set scalar parameters

[zealous cedar]

Fantastic! It works! Thank-you, I’ll look into variables more now I’m delving into BPs.
Quick question, I plugged the exec from the Set Light Function Material into the Set Random Local Float Variable just after it - is this okay, or should I establish this local variable beforehand, such as after the Construction Script node at the start? Does it matter at all?

[brazen pike]

Can you send a screenshot?

I'm not quite following

[mental trellis]

If it works!

[white elbow]

How come OnComponentBeginOverlap doesn't detect overlapping with default cubes?

[glass stump]

are you using box collision?

[mental trellis]

Maybe they don't have collision?

[prime stump]

Hi, does anyone know if there is any difference in performance between placing meshes individually or using a spline tool to place them?

[glass stump]

How do I save variables that are not of the player character?

[mental trellis]

What sort of variables?

[white elbow]

figured it out, default cubes by default don't generate overlap events

I thought it only has to be ticked on the overlapping component only
