Can someone help me, I've been creating this level manager code to create new levels but the problem is that in unity it tells me to put the

GameObject Mole = GameObject.FindWithTag("Player")

In a different area of the code, but when I do the code breaks and there is a tun of red underlining a lot of my code.

[slender nymph]

you shouldn't be moving the entire line into the Start method, just assign the variable in Start

but also ideally you wouldn't be using FindXXX anyway because there are typically much better ways to reference an object, like by using a serialized field

[unique pagoda]

I genuinely wish I knew how to code😭💔

[slender nymph]

there are beginner c# courses pinned in this channel that will help you learn

[wild cove]

I'm just beginning, whats a serialized field?

Ik I was doing a mini project for myself to practice what I've learned

[slender nymph]

did you know that typically blue text means it is a link

[wild cove]

No i didnt know that

thanks

[unique pagoda]

Guys I failed so bad

OH MY BAD

I didn't know

That's my bad

[wild cove]

Thank you for the help, that fixed a big problem of mine and the code is now working! And I learned what serialized fields were.

[verbal swift]

game dev beginner has alot of rlly informative tutorials but goddd r they long

idk if youve heard of him but his videos have saved me so many headaches already

https://www.youtube.com/watch?v=Zrt0iEBBkRM one hour of actually applied learning 😢

the chapters r rlly helpful tho

[crimson laurel]

tryna get a random point within a 2d collider, but if one axis is longer than the other, it'll extend on that axis further outside of the bounds

// Script2
public static Vector2 GetRandomPointInsideCollider(Collider2D boxCollider)
    {
        Vector2 extents = boxCollider.transform.localScale / 2f;
        Vector2 point = new Vector2(
            UnityEngine.Random.Range( -extents.x, extents.x ),
            UnityEngine.Random.Range( -extents.y, extents.y )
        );

        return boxCollider.transform.TransformPoint(point);
    }

blue spheres being the points that I want to stay inside the box

[rich adder]

instead of scale why not just use bounds of collider ?

[crimson laurel]

if it's a better method sure, what's the method for getting it?

[rich adder]

https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Collider-bounds.html

you could probably run some type of while loop with a max and use also ?https://docs.unity3d.com/6000.3/Documentation/ScriptReference/Collider.ClosestPoint.html

[rich adder]

this could also work too

  Vector2 RandomPointInBox(BoxCollider2D box){
        Vector2 local = new Vector2(
            Random.Range(-0.5f, 0.5f) * box.size.x,
            Random.Range(-0.5f, 0.5f) * box.size.y
        );
        return box.transform.TransformPoint(local + box.offset);
    }```

[wintry dew]

anyone know how i can make sure the menu size stays reasonable for different aspect ratios? for some it just turns to a single line for others its gigantic

[rich adder]

this isn't a code question

#📲┃ui-ux

[wintry dew]

oh yeah

[crimson laurel]

oh I should've said that it's just a collider2d and not a boxcollider

unfortunately this puts it super far away, but I did have to change boxCollider.size.x -> boxCollider.transform.localScale.y etc

dont think that'd impact it though

I shouldve changed the var name lol

[rich adder]

why not use the specific collider type instead tho? scale just seems idk.. you're getting the whole object not the collider itself

[crimson laurel]

I dunno man, I'm a beginner for a reason

not sure what the best method is, just using what I find

[rich adder]

"best" depends on many things, if you want the point within that collider and its gonna be a box anyway (from your screenshot it seems) the method I sent would be good

[frosty yarrow]

void OnSneak(InputValue val)
{
if (val.isPressed)
{
speed = 5f;
Debug.Log("Sneaking: " + speed);
}
else
{
speed = 10f;
Debug.Log("Normal: " + speed);
}
} when i stop holding it is still sneaking

[twin pivot]

when do you think that piece of code gets triggered?

[rich adder]

probably depends how did you put the action type / mode

[frosty yarrow]

when i press it

the interaction is holding

[twin pivot]

so what do you think happens when you stop holding it

[frosty yarrow]

speed return to normal but when i tetsed is not working

[rich adder]

"Hold" isn't doing what you think its doing, probably

[frosty yarrow]

so like what to do

[rich adder]

You can remove the interactions you have now and just set Action Type to Value

that should give you the hold behavior cause it will trigger isPressed and isPressed = false on let go

[frosty yarrow]

it worked tysm but what is the difference

[rich adder]

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/api/UnityEngine.InputSystem.InputActionType.html#UnityEngine_InputSystem_InputActionType_Value
in this case is just easier but technically you can use button too with performed and canceled but I only know it this way because I don't use SendMessages mode
, gives you kind of like a 0 or 1 held

[frosty yarrow]

alr thx

I really struggle to understand that part 😕 I just finished creating a tilemap so I don't use an external editor anymore but I don't know how to do the next part of linked the stuff to code 😬

[rare condor]

rect.rect.Set(0, 0, settings.texWidth, settings.texHeight);
Debug.Log(settings.texWidth);
.. So strange, the log shows size 100x100 which is totally different than texWidth which i already debugged at same point being over 4000

RectTransform rect = previewImage.GetComponent<RectTransform>();

Basically it's not changing the image component size with code.

[ivory bobcat]

What is a rect? Often, properties like these will have returned a copy and modifying the copy would not reflect on the actual property. Perhaps a warning should have been thrown as well about modifying a non variable.

[rare condor]

I tried to set it directly without variable too

previewImage.GetComponent<RectTransform>().rect.Set(0, 0, settings.texWidth, settings.texHeight);

That doesn't do anything, compiles though.

[ivory bobcat]

This isn't setting it directly...

Don't use the Set method

Like.. transform.position.Set(...) would also not do anything..

[rare condor]

It is a UI image, i just want to set its width and height

[ivory bobcat]

Instead copy the rect, modify the necessary data and assign it back to the text property. A read only property. Simply the calculated rect. You'll need to modify other properties to adjust the calculation.

[keen dew]

rect is read only

You have to set the individual properties

[rare condor]

Well, this seems to be acceptable workaround:
previewImage.transform.localScale = new Vector3(settings.texWidth, settings.texHeight, 1f);

[naive pawn]

are those tiles just plain tiles with the sprites? pretty sure you can make prefabs with tile components to store data

[median hatch]

if (!playerController.isFightMode)
            {
                targetDir.y = 0;
            } else
            {
                float enemyHeight = playerController.playerEnemyList.enemyList[0].transform.position.y - bulletSpawn.transform.position.y;
                targetDir.y += verticalSpeed * enemyHeight * Time.deltaTime;
            }

could anyone help here? i got this isometric game, if im targeting an enemy that is above ground then i want the bullet.y to aim towards them

[keen dew]

What is targetDir used for? It doesn't make sense to multiply a direction by deltatime

enemy position minus bullet position is a direction from the bullet to the enemy that includes the y difference

[median hatch]

Vector3 targetDir = (playerController.aimPoint - bulletSpawn.transform.position).normalized;

its a free aim isometric game

but im struggling with the y axis

because nothing seems to feel intuitive when shooting upwards

[keen dew]

(playerController.playerEnemyList.enemyList[0].transform.position - playerController.aimPoint).normalized.y is the Y axis for the direction

(or possibly - bulletSpawn.transform.position) I'm not sure what those are)

[median hatch]

well the idea is that the bullet.transform.forward will always be where the mouse is

my idea would be to set the bullet.y to the drone, but again even if its correct it feels off, since in some angles you put your mouse on top of the drone and the bullet still misses

i feel like its also a problem from the camera angle itself

[past yarrow]

I don't know what you mean by "plain tiles with the sprites", but I just made a quick png image in Aseprite, then export it to Unity, then created a Tilemap and sliced the png image into multiple colored tiles like you can see in the image, then I painted my level like that 🤷‍♂️

[ivory bobcat]

https://docs.unity3d.com/6000.4/Documentation/Manual/tilemaps/tiles-for-tilemaps/scriptable-tiles/create-scriptable-tile.html
The Paint with the scriptable tile section would explain how to use it in the Unity Editor

[slender nymph]

so you remember how i said that you need to inherit from TileBase to create a tile that you can assign your data to? you can't skip that step and expect it to magically JustWork™

[naive pawn]

that's exactly what i mean by "plain tiles from sprites"

you weren't supposed to do that

[past yarrow]

The issue is I don't know how to do that because it's too vague 😕
From what I understood the steps would be :

• Create a script (what name should I give it as I don't know what would the purpose be)
• Inherit from TileBase
• Give it properties like position (x and y), type (the enum I used before), what else ?
• What's next ?

[slender nymph]

how is "inherit from tilebase" too vague? do you know what inheritance is?

also you were provided with a link that gives an example of doing so

[past yarrow]

No, the inheritence part isn't the "vague" part, the vague part is all the steps and what's the purpose of it because I'm really confused

[past yarrow]

Then I'm really confused on what I'm supposed to do 🙁

[slender nymph]

inherit from tilebase. give that class the properties you want. create tiles using that class. that's literally it. there's no other mystery steps involved

then once you are looping through the tiles you have concrete information you can get directly from the tiles instead of trying to convert colors into that same information

[past yarrow]

"create tiles using that class", this part confuses me because I don't know how to tell unity to take the class that inherit from TileBase and use it in the TilePalette so I can paint with it

[slender nymph]

so have you just ignored the links that have been provided about how to create and use scriptable tiles? the most recent of which was linked to you half an hour ago?

[past yarrow]

I quick read it and it confuses me even more

[slender nymph]

well good luck then. you've been at this for days and at this point i'm no longer interested in helping

[past yarrow]

I need to find a video explaining all that stuff

[undone wave]

whenever i load a pretty intensive scene, there's a noticeable lag spike at or near the beginning

this (i presume) means that most of the lag comes from garbage collection

which isn't a problem on its own, but the problem is that for some reason, it keeps happening after the loading animation has completely finished

        transition.SetTrigger("Start");

        if (sceneLoadStarted != null) sceneLoadStarted();

        yield return new WaitForSecondsRealtime(transitionEnterTime / animationFramerate);

        // loading scene added for testing; basically an empty scene that contains nothing
        
        AsyncOperation asyncLoad = SceneManager.LoadSceneAsync("Loading");

        while (!asyncLoad.isDone)
        {
            yield return null;
        }

        // i tried adding GC.Collect() here; didn't improve anything

        

        asyncLoad = SceneManager.LoadSceneAsync(sceneName);

        while (!asyncLoad.isDone)
        {
            yield return null;
        }

        // i tried adding GC.Collect() here as well; didn't improve anything

        // added yield return new WaitForSecondsRealtime(1) to check if this was indeed a problem with the lag spike and not something to do with animators, etc.
        // turns out it was indeed the lag spike affecting the exit transition

        Time.timeScale = 1;
        AudioListener.pause = false;

        transition.SetTrigger("End");

        yield return new WaitForSecondsRealtime(transitionExitTime / animationFramerate);
        if (sceneLoadFinished != null) sceneLoadFinished();```

[naive pawn]

then why haven't you
you've just elected to pretend that the instructions don't exist?

[undone wave]

i think it would need a bunch of optimisation to fix the whole gc issue, but for now, is there a method to contain the lag within the loading screen (between the two SetTriggers)?

current behavior (note the fade out animation instantly snapping)

intended behavior (delay added manually)

[wicked cairn]

You could load the scene additively, meaning your main scene has the functionality & the secondary scene has the map. This way it loads in the background

Oh, I think in the video you already do that my bad

[undone wave]

wait no, could you elaborate a bit further?

[slender nymph]

they're saying to basically use LoadSceneMode.Additive, then you can also control when the old scene gets unloaded and can yield that operation as well, that way you can be sure that the spike you're seeing happens during the transition instead of right at the beginning of the new scene

[undone wave]

ohh, thank you

[slender nymph]

so order of operations would be

wait for additive scene load
wait for old scene unload
transition to new scene

[past yarrow]

I was trying to understand from the explaination I received on this discord first

I have this code for now but don't know what to do with it and if it's complete enough or not:

using UnityEngine;
using UnityEngine.Tilemaps;

public class TileMap : TileBase
{
    private Vector2Int position;
    private EN_TileType tileType;
    
    public override void RefreshTile(Vector3Int position, ITilemap tilemap)
    {
        base.RefreshTile(position, tilemap);
    }

    public override void GetTileData(Vector3Int position, ITilemap tilemap, ref TileData tileData)
    {
        base.GetTileData(position, tilemap, ref tileData);
    }
}

[undone wave]

ok hmm
seems that didn't work

[slender nymph]

show what you tried

[undone wave]

wait no, upon closer inspection it does "work"

the code is pretty simple i think

        Scene currentScene = SceneManager.GetActiveScene();

        AsyncOperation asyncLoad = SceneManager.LoadSceneAsync(sceneName, LoadSceneMode.Additive);

        while (!asyncLoad.isDone)
        {
            yield return null;
        }

        asyncLoad = SceneManager.UnloadSceneAsync(currentScene);

        while (!asyncLoad.isDone)
        {
            yield return null;
        }```

but it does this now

[slender nymph]

is this transition part of the scene that is being unloaded? or is it in its own scene/DDOL scene?

[undone wave]

as far as i know, the entire transition part is in dontdestroyonload

they're all part of the screen manager object

(which in the video is in ddol)

[slender nymph]

then you need to show more context if you need more help with it.

[naive pawn]

you probably shouldn't name it TileMap, since each instance of this represents a single tile, not the tilemap

[undone wave]

can i ask which context exactly i should send?

[undone wave]

first off, this is the entire 'LoadScene(string sceneName)' coroutine, every other script that changes the scene in some way just invokes this through an event

[past yarrow]

so should I call it Tile?

[undone wave]

with that in mind, this is the code for the screen manager

    public static ScreenManager instance;

    public float transitionEnterTime;
    public float transitionExitTime;

    public float animationFramerate;

    public Animator transition;
    public void changeScene(string sceneName)
    {
        StartCoroutine(LoadScene(sceneName));
    }

    static public event Action sceneLoadStarted;
    static public event Action sceneLoadFinished;

    IEnumerator LoadScene(string sceneName)
    {
        ...
    }

    private void Awake()
    {
        if (instance == null)
        {
            instance = this;
        }
        else if (instance != this)
        {
            Destroy(this.gameObject);
        }
        DontDestroyOnLoad(this);

        
    }

    private void Start() // used only for when the game is first started
    {
        StartCoroutine(StartScene());
    }

    IEnumerator StartScene()
    {
        yield return new WaitForSecondsRealtime(transitionExitTime / animationFramerate);
        if (sceneLoadFinished != null) sceneLoadFinished();
    }```

the animator just looks like this
with 'Start' triggering Scene Transition End to -Start
and 'End' triggering the opposite, both of them are just a simple 0<->1 linear alpha transition

and that's literally all the code related to scene loading/screen transitions

any other instance of changing the scene through code just looks something like this

ScreenManager.instance.changeScene(sceneName);```

[naive pawn]

there's a class already named that, so that could get confusing, consider a more specific name

[past yarrow]

like what ?

[undone wave]

nevermind, the problem was with the cameras
i just put the intermediate 'loading' scene back in between the two scenes, and then set the loading scene's camera priority to a value lower than the others, so it is never prioritized if there are other cameras on scene, stopping the flashing

[naive pawn]

CluedoTile, SourceTile, MapTile, RoomTile, etc

[final sluice]

Is there a function I can use to get a vector from an object current position to another point without having to subtract them ?

[past yarrow]

Thanks

[undone wave]

...and a new problem just arose

[undone wave]

the new code works perfectly fine in the editor, but for some reason, it reverts back to the linked video's behavior when i build it

[naive pawn]

subtraction is that function. it's literally a function

[rich adder]

probably not? why would you not want to subtract...thats literally is how direction vectors work
https://docs.unity3d.com/Manual/scripting-vectors.html#:~:text=Subtraction

[naive pawn]

there are the Transform/InverseTransform functions, some take into account the local space including rotations and scaling

you could use those if you have a Transform

[undone wave]

update:
the new code works like this:

• step 1. load 'loading' scene (additive)
• step 2. unload current scene
• step 3. load 'new' scene (additive)
• step 4. unload 'loading' scene

i inserted

Resources.UnloadUnusedAssets();
GC.Collect();```
between step 3 and 4

and now it kind of fixed the issue i replied to

the problem is that now the behavior is completely inconsistent

[final sluice]

I feel stoopid, thank you

[verbal swift]

why are there so many collision functions and why cant i get any of them to work

Im trying to use OnCollisionStay for a grounded check

[naive pawn]

because they are for different things, and likely because you're doing something wrong

[verbal swift]

but its just not returning anything

[naive pawn]

are you working in 2d or 3d?

[verbal swift]

3d

[naive pawn]

that's not how layers work

[verbal swift]

yes ive applied the groundmask to the ground objects

[naive pawn]

when debugging messages, make sure to debug outside of any conditionals

your conditional is wrong there

[verbal swift]

whats the correct way then

[naive pawn]

what's the type of WhatIsGround

[verbal swift]

it couldve went red for me

layermask

[naive pawn]

that's when you have errors, this is a bug

[naive pawn]

and what type is gameObject.layer

[verbal swift]

a layer

[rich adder]

layermask != layer

[verbal swift]

and ive set my layer to ground

[slender nymph]

https://unity.huh.how/bitmasks

[naive pawn]

a layermask is a lot of layers, you can't compare the 2

[verbal swift]

i dont think i can assign a gameobject layer mask in the if statement

how do i make the if statement work then

[rich adder]

there are functions you can use in the LayerMask struct or make your own

eg LayerMask.NameToLayer

[naive pawn]

you don't need to assign anything

[rich adder]

iirc you can also do something like

if ((layerMask.value & (1 << gameObject.layer)) != 0)``` but won't work if you have multiple layers in layermask

[naive pawn]

@verbal swift there is a section that explains how to use a layermask to check a layer in this article.

[naive pawn]

why wouldn't it work

that's the point of &

[verbal swift]

i only use layermask to assign my layer in unity

so i could change it if i wanted 2

i am NOT gonna try wrap my brain around multiple layers

[rich adder]

ohh didn't know that, I just read this a while ago when i saw this on the unity discussions

[naive pawn]

0b101 & 0b100 -> 0b100 != 0
0b101 & 0b010 -> 0b000 == 0
0b101 & 0b001 -> 0b001 != 0

[vague kayak]

hello chat, I'm having an issue where I have an InputActionReference field on a scriptable object and I'm trying to set it with my input actions. For some reason, it's not working at all. I'm able to click the button that shows you the possible assets in your project that you can set it to, and they show up there, but clicking them doesn't set it. Any ideas what could be wrong here? Or is this a bug with unity?

[rich adder]

probably a bug because its an asset so it should not be scene dependent or anything cross references

[vague kayak]

oh boy

looks like it works by making the field of type ScriptableObject and casting to InputActionReference in code... 😭

[rich adder]

thats pretty weird..let me try that

[rich adder]

ya no it works fine for me, must be a bug

[vague kayak]

damn

this is rough

[rich adder]

are you using Unity LTS ?

[vague kayak]

yeah

[rich adder]

scuffed

[naive pawn]

have you tried a restart?

[vague kayak]

several times

[naive pawn]

what about a library reset?

[vague kayak]

havent done that

good idea

[grand snow]

Does it matter if the inputs are set as the project global ones or not?

[vague kayak]

didn't work

[vague kayak]

i dont know, how would you create an input action outside of the global ones?

[grand snow]

Well you can but dont worry about it

[eager needle]

Hey guys. Got some positionning issue 😄 on my 2d side scroller. The goal is to make an ennemi shoot a laser at a player. but since the enemi is patrolling, the forward direction of it is changing depending on the patrol side. I can't make it use the red vector in local space to generate linerenderer from the spawnpoint on the ennemy eye to the forward direction.

the turkey point left but the ray is shoot on the right.

[slender nymph]

i feel like you've already been instructed in this channel how to fix that but you chose to ignore that advice

[eager needle]

I haven't ignored it actually. I flipped the sprite to make it by default on the right as advised.

[naive pawn]

and how do you turn around?

that wasn't the only thing i advised

if you're flipping the sprite or using a different sprite to turn around, you will either need to mirror the laser origin programmatically or have 2 origins for either direction

if you're rotating or scaling the gameobject to turn around, you can use the direction vectors of that laser origin directly, because it will be turned around as well

[eager needle]

I changed the way I am patrolling. I now use transform.translate and doing a ground check to see when I need to change direction to go on the other side.so it's not just a flip anymore. the whole objet is changing direction. the laser origin is a child of the enemy so my understanding it's going to change direction as well. the thing here is to find the proper forward direction of the laserOrigin. to instantiante the index 1 of the line renderer on the proper side.

[slender nymph]

is the red arrow for the laserOrigin pointing in the direction of its "forward" direction? if so, then its transform.right is the forward direction

[eager needle]

oh nevermind. I just checked. the local direction is not changing when the enemy change side. so that is the issue.

[naive pawn]

this doesn't really answer my question. what exactly are you using to "flip" the object

[eager needle]

gotcha. here is the flip

void Flip()
    {
        enemyRenderer.flipX = !enemyRenderer.flipX;
        
        Vector3 localPos = groundCheck.localPosition;
        localPos.x *= -1;
        groundCheck.localPosition = localPos;


        speed = -speed; // Inverse la direction
    }

[naive pawn]

so you aren't flipping the object, just a few specific things

the sprite and the ground check and the direction of travel, but notably, you have not flipped the laser position

if you actually flip the object, anything using local space will also be flipped

you can do so by rotating or scaling the transform, like i mentioned

[naive pawn]

just a tip, with that kind of thing, you'd also probably want to store what direction you're facing and then check that when you actually use the speed or whatever, rather than having this hidden state

you already have a state, just make it explicit to make it easier to work with

but that probably won't be very necessary once you just flip the whole object

[eager needle]

Ok. thanks for the advice ( again). I will implement some rotation in there so I will be able to properly use the vector. sorry to have listen on the first time.

[zealous talon]

hi, i wanna make a flash effect (like most rpg) when my enemy is taking damage in my rpg. the problem is that all tutorials that i find use sprite renderer, and i have a model took from sketchfab. does anyone have any idea on how to do that

of course the models are not mine, but i hope i explained the idea

a shader / material swap

[frail hawk]

post processing is also a solution

[stone glacier]

by the way, how to make an npc following you smooth? like transform.LookAt(Player); is moving too instant, and i want to add a small delay to it, and some noise?

and how to script that npc's chooses a path? like they not following you straight, and not walking to walls

i cant imagine the logics for these things

[rich adder]

simple. navmesh

[stone glacier]

this is so cool, thanks, i learned the basics

so basicly i make an empty object, give a navmesh surface script to it, generate the world in the empty with ground layer, give the enemies agent script, and then bake it when the game is ready?

because it will be a random generated sandbox game

For my game, I’m relatively new to coding and I’m wondering how to go about coding a mechanic similar to the drill wisp in sonic colors. Basically I want to be able to dash into a wall, and then be able to pop out on the other side

Does anyone have any ideas? And how complicated would it be

https://youtu.be/I6AJH0UFvDo?si=C6kwNFiC19u0l41D

[tired python]

trying to make the box collider and sprite have the same area, can anyone see the problem here?

how the hell do i even begin to manage this from a script?

the constant required to make them the same size would be so peculiar

[thorn holly]

You could leave the sprite scale as 1 and then adjust the collider radius instead of scale of the collider gameobject

If that makes sense

If you do it that way they all have scales of 1 1 1

[tired python]

and i only need to change the colliders scale in that case?

[thorn holly]

Don’t change the scale through transform, change it in collider settings

I think the property is called radius

Under circle collider 2d component

[tired python]

oh ya sry

i already have a radius set...

and i changed all the scales to 1

doesn't rly work i guess

[thorn holly]

Change all the scales to 1 and then…change the radius?

It’s not set in stone

You can set the radius

[tired python]

changing the radius doesn't change the circle sprite, i want the circle collider and the circle sprite to match in radius

[thorn holly]

Ah, in that case set all the scales to 1, set the circle collider radius to match the sprite, then scale up the colliders transform - because the sprite gameobject is a child of the collider, the sprite transform will scale with the collider transform

[tired python]

thx, works. so i am assuming that if i wanna add upgrade features to the tower later on which can increase the range, ima have to increase the Scale in script?

[thorn holly]

Yes, increase the scale of the parent object and it’ll increase the scale of the child as well

So in this case the parent is the collider so increase the scale of the collider transform

[tired python]

[tired python]

I have been using
public class UnitRelocatorScript : MonoBehaviour, DragHandler,IPointerClickHandler but when i stop dragging the gameObject this script is attached to, the OnPointerClick gets called out too

I want it to be such that, if I am dragging the object, only the OnDrag method gets called, whereas if I only click on the object, only the OnPointerClick gets called

cus the way it is now, it recognises dragging as a click too

[cosmic dagger]

Probably because when you release the drag and let go of the mouse, it also releases, which registers a click . . .

[tired python]

i mean...i know that, i don't want it to be like this.

[tired python]

i kinda guessed that was what was happening using logs

[cosmic dagger]

I thought you just said you don't want it to be like that . . .

[tired python]

did that clear up the confusion?

[cosmic dagger]

Does it recognize dragging as clicking, or does it only register a click when you release the mouse, regardless of the mouse being dragged beforehand?

[tired python]

latter

[cosmic dagger]

I would use a bool check. If you're dragging an object, set the variable, then check that variable in the pointer click method. If it's true, then you know it was a drag and not supposed to be a click . . .

[tired python]

hmm, i always have confusion as to when i should use flags cus i don't know about all the events there are and i worry that there might be an event out there which does exactly what i want and i might just be overcomplicating stuff

[cosmic dagger]

Just check the documentation. If you search for pointer events, you'll see all the different events under "Interfaces" of the "EventSystem . . ."

[cosmic dagger]

Basically, Unity registers both inputs because the mouse releases on the same object when the drag ends

Inside of OnPointerClick, you can check if the position of the object (being dragged) is the same. If it's the same, it was a click; if the position is different, it was a drag, and therefore, not meant to be a click . . .

Oh, even better, PointerEventData has an isDragging bool. Check that inside of OnPointerClick to determine if it was a drag or not . . .

[tired python]

ehhhhh, this works, do i really have to do it the way you suggested?

[cosmic dagger]

If it works for you, that's fine. I'd use the last method I suggested. That seems the easiest, but it's your game, your choice . . .

[tired python]

thx a lot

[brave patio]

Hey guys does anyone know why OnCollisionStay2D and OnTriggerStay2D only detect if the player is on its borders? Both work as intended when the two rigidbodies are overlapping in borders, but once one is inside the other it seems to not function at all.

Works fine in the first image, but in the second image it doesnt detect any collision

[naive pawn]

which one are you using? are they colliding or is one a trigger?

it's probably because the outer shape only has edge collision

you'd need to have it generate polygons (or a similar option)

[ivory bobcat]

On collision stay should not allow the two objects to overlap

If they're inside one another (and no longer repelling each other) they could possibly be resting. Where...

Collision stay events are not sent for sleeping Rigidbodies.
https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionStay2D.html
When Rigidbodies fall to rest - a box landing on the floor - they will start sleeping. Sleeping is an optimization which allows the Physics Engine to stop processing those rigidbodies.
https://docs.unity3d.com/410/Documentation/Components/RigidbodySleeping.html

[brave patio]

That ones a trigger

Switching it to Polygon rather then outline fixed it - Thank you so much!!

I need help with my code above. I have a GameObject List called allObject and when I proceed to clear it. The List stay without any effect to it. Even if I tried to remove the object directly it still sticks. Can someone help me find where it being added constantly at or jyust where I messed up?

[keen dew]

Well you add more stuff to it on the next line after .Clear() ?

[safe root]

What do you mean? What other thing need to be added?

[keen dew]

I don't quite understand what the problem is

allObject.Clear();
allObject.AddRange(foundObjects);

After this allObject will contain foundObjects. Why do you expect it to be empty?

[safe root]

So the reason I have it like that is cause i'm trying to get rid of a object that is now a null but it doesn't work

The null is still there even after I tried to remove it twice

[sour fulcrum]

AddRange doesn't do any null checking or anything

if your adding a range that includes a null that will include that null

[keen dew]

Where are you trying to remove it? Nothing else in that code modifies allObject

[safe root]

But the foundObject should be changing everytime as the Object with the objectToFind String will be less as that object got destoryed

[safe root]

In the OnCollisionEnter I have this line

allObject.Remove(collision.gameObject);

[keen dew]

That does nothing because you don't use the list after doing that. FindNearestObject clears the list so whatever you did to it earlier is also cleared

[safe root]

I understand that, but that code, I had before I did the FindNearestObject clear and still. That object did not get removed from the list

[sour fulcrum]

semi offtopic but unless this code assumes more objects will spawn or be removed during the search you should really get the objects by tag before the while loop rather than at the start of it

[keen dew]

Either it wasn't in the list or you didn't check properly

[safe root]

Object are activly spawning

[sour fulcrum]

find related functions are pretty bulky performance wise and having them in a loop like that is a bit of a red flag

[safe root]

It's in the list as when the Object get's Destroyed. The object becomes null

[sour fulcrum]

Ideally those objects should be telling the roomba (or something else) about their existence when they spawn and despawn

rather than you constantly checking for them

[safe root]

I wasn't to sure how to do that so I came with best thing I could

[sour fulcrum]

This is a very common beginner conclusion no stress

have you used singleton's before?

[keen dew]

It won't be destroyed until the end of frame. So what happens is you call Destroy -> FindGameObjectsWithTag finds the object -> end of frame it becomes null

[safe root]

I have not, taking a look at video right now

[safe root]

I see, but then why doesn't the clear not work still?

[keen dew]

Because you add all the stuff that FindGameObjectsWithTag found back into the list

And FindGameObjectsWithTag found the thing that you tried to remove

[safe root]

Oh, is it not resetting?

[keen dew]

What is not resetting?

[safe root]

The FindGameObjectWithTag. As I thought, once a object is deleted, that tag is not gone since the object activly not there no more to be read. SO when it comes back to the top to restart the cycle, FindGameObjectOfTag would redo it's list with everything but the object that got destoryed

[keen dew]

Yes but #💻┃code-beginner message <-- the object is not yet destroyed when you call FindGameObjectWithTag

[sour fulcrum]

Ok, it's worth knowing but basicially what it does is gives you a good way to find a specific object from anywhere, the reason i bring it up is to do the thing i suggested you would basicially be like

public class RoombaTargetOrSomethingRather : MonoBehaviour
{
  RoombaAI roomba;
  private void OnEnable()
  {
    roomba = //Find this via a Singleton or even by tag if you want but that's unideal longterm
    roomba.RegisterTarget(this) //This means the object/component runnning this code (itself)
  }

  private void OnDisable()
  {
    roomba.UnregisterTarget(this)
  }
}

public class RoombaAI : MonoBehaviour
{

  public void RegisterTarget(RoombaTarget target)
  {
    //Probably add to your list
  }

  public void UnregisterTarget(RoombaTarget target)
  {
    //Probably remove to your list
  }
}

If you flip the logic like this (the many telling the single thing when they exist and don't exist rather than the single thing looking for the many) it ends up working a lot more smoother conceptually and practically

It's like your friend is coming over and your waiting to hear the door bell ring rather than just lurking at the window

[safe root]

I delayed the destoryed and still nothing happened

[safe root]

Oh, this seems a lot more useful. I'll have to do some studying

[sour fulcrum]

Yeah, once you do it once you will probably understand it nicely

Ideally you would use a Singleton for this but since that's a new concept for you feel free to just find it by a tag or something so your not learning two things at once

[keen dew]

Well that would make it worse, wouldn't it? You need to delay the FindGameObjectWithTag call instead

[sour fulcrum]

(sorry for completely re-routing your help btw Nitku, just seems like shifting to that different approch will solve a lot of problems fundementally)

[safe root]

It's something to try update my code, once I get this version working first

[keen dew]

Yeah don't get me wrong, this is solving the original problem but not a good way to do it in general

[safe root]

Gotcha, but I do have this one question. I just can't seemed to get, even after delaying the destory. The allObject.Remove(collision.gameObject); still doesn't function

[keen dew]

How do you know that?

[safe root]

Cause the object stays in the list, I can see the list in the inspector

[ivory bobcat]

You need to delay the repopulation of the collection rather than destroy. Destroy doesn't happen immediately.

[safe root]

By a WaitForSecond?

[keen dew]

You can't use the inspector to check that because right after that you call Remove you start the FindNearestObject coroutine which modifies the list again. So you're seeing what FindNearestObject does, not what OnCollisionEnter does

yield return null is enough

[sour fulcrum]

(this waits a frame)

[safe root]

I see, I really didn't think how fast that list was getting active cause of destory not happening as soon I thought it would. Thank you

[safe root]

This also just help me a but cause I just seen what {Get; Private Set:} is and that also gonna be nice to use

[sour fulcrum]

properties are cool yeah

if you want them to show up in inspector you need to do [field: SerializeField] on them btw

[safe root]

I know that, I've use that a bit now. Just never seen {Get; Private Set:} so that fun to learn

[pallid forum]

Hey there, I'm trying to learn how to code tapping on an object (for mobile)
So uhh.. the problem is... I think the raycasting isn't finding anything. Not sure why, but possibly the position that given to it is incorrect. Can someone help me to fix this please?

here's what I check so far:

1. I did not forgot to add collider
2. Both Action ref is fine. (tapAction is Button type and TouchPosAction is Vector2 value)

here's the code

public class TapDetector : MonoBehaviour
{
    public Camera mainCamera;
    public InputActionReference tapAction;
    public InputActionReference touchPositionAction;

    private void OnEnable()
    {
        tapAction.action.performed += OnTap;
        tapAction.action.Enable();
        touchPositionAction.action.Enable();
    }

    private void OnDisable()
    {
        tapAction.action.performed -= OnTap;
    }

    private void OnTap(InputAction.CallbackContext context)
    {
        Debug.Log("Tap detected");
        
        Ray ray = mainCamera.ScreenPointToRay(touchPositionAction.action.ReadValue<Vector2>());
        RaycastHit hit;
        Debug.Log("Ray origin: " + ray.origin + ", direction: " + ray.direction);
        if (Physics.Raycast(ray, out hit))
        {
            Debug.Log("Hit object: " + hit.collider.gameObject.name);
        }
        else
        {
            Debug.Log("No object hit");
        }
    }
}```

Dang, this is big wall of code.

[keen dew]

You have the logs there so you should know if it finds anything or not, does it print the "no object hit" log?

[pallid forum]

Yes, It printed that.

[keen dew]

Do the objects have 3D colliders?

[pallid forum]

Oh dang, I didn't see that coming.
Yeah, it has 2D. So uhh, do I change it to 2D?

[keen dew]

Physics2D raycast, yes

Possibly need to use ScreenToWorldPoint as well

[pallid forum]

Alright, I'll check and make some changes. I'll let you know if it's fix.

[pallid forum]

I don't think I do know how to figure this out on my own.
Where do I use ScreenToWorldPoint?

[frail hawk]

can we clarify, are your objects normal gameObjects or ui elements

i see many beginners mix things and wonder why it won´t work

[pallid forum]

I think it's gameObject?
I create 2D sprite of those things that are in create section. The capsule, triangle, cirle and square.

[keen dew]

It should be something like this:

Vector2 worldPoint = mainCamera.ScreenToWorldPoint(touchPositionAction.action.ReadValue<Vector2>());
RaycastHit2D hit = Physics2D.Raycast(worldPoint, Vector2.zero);

if (hit.collider != null)
{
    ...
}

[pallid forum]

Sooo, yeah I think everything is fine except one thing.
It turned out that the TouchPos value always giving out this

no change of number. Only this number.

What could possibly be the cause?

Is my action map wrong?

[frail hawk]

are you displaying the worldPoint

[pallid forum]

not sure if I do?
what do you mean by that?

[frail hawk]

you now that message you have there, what is it

[keen dew]

It's not clear what you're logging. Show the code you have now

[pallid forum]

private void OnTap(InputAction.CallbackContext context)
    {
        Debug.Log("Tap detected");
        Ray ray = mainCamera.ScreenPointToRay(touchPositionAction.action.ReadValue<Vector2>());

        Vector2 worldPoint = mainCamera.ScreenToWorldPoint(touchPositionAction.action.ReadValue<Vector2>());
        RaycastHit2D hit = Physics2D.Raycast(worldPoint, Vector2.zero);
        Debug.Log("Ray origin: " + ray.origin + ", direction: " + ray.direction);
        if (hit.collider != null)
        {
            Debug.Log("Hit object: " + hit.collider.gameObject.name);
        }
        else
        {
            Debug.Log("No object hit");
        }
    }```

anyways, I didn't change any other part than this.

[keen dew]

The code doesn't use ray anymore so it doesn't matter what its value is. You can just delete it

[pallid forum]

oh yeah.

but, how about that it is not finding any object?

[neat bay]

I'm so confused - baked a flowmap using ray casts in a scene and a predetermined flow direction if the ray doesn't hit anything. Printing the color, the green value is 0.5 - in a color picker, the green value is 0.5 - VISUALLY, the green looks about 0.5 - but according to the shader green is nowhere near 0.5

Heres the code for baking a missed ray, but i don tthink this is the problem since the flow map baked correctly

Color undisturbedFlowDirectionColor = FlowDirectionToColor(undisturbedFlowDirection);
Debug.Log(undisturbedFlowDirectionColor);

private Color FlowDirectionToColor(Vector2 direction)
{
    Vector2 normalizedDirection = direction.normalized;
    Vector2 remappedDirection = new Vector2(normalizedDirection.x / 2.0f + 0.5f, normalizedDirection.y / 2.0f + 0.5f);

    return new Color(remappedDirection.x, remappedDirection.y, 0);
}

[neat bay]

the orange is the "undisturbed flow" and are the pixels that should have a green value of 0.5

the undisturbed flow direction is set in the inspector as (1, 0)

a visual bug

• try restarting
• are you on an older patch or an unstable release?
• are your drivers up to date? what os are you on?

[daring star]

restarting helps but it happens again

[daring star]

no, im on lts

[naive pawn]

that doesn't exactly fully answer that question, you could be on a buggy patch release of an LTS minor version

what version are you on?

[daring star]

6000.0.63f1

[ivory bobcat]

Are you receiving any errors in the console window?

[daring star]

no

[ivory bobcat]

Maybe try the latest LTS?

[naive pawn]

there's a new patch, perhaps try that

[naive pawn]

6.0 to 6.3 is a non-insignificant jump afaik?

especially considering minor versions seem to basically be treated as semver major currently

[runic lance]

yeah it's a significant commitment to update minor version

from my experience 6.3 is still not very stable either

they could also try resetting the layout or checking if there's any custom editor scripts running

[mild furnace]

Ugh vscode has gotten significantly slower yet again.
Its more efficient to close vscode if I want to compile and test in editor

Maybe its time to revert back to a version ~2022 and use the old vscode unity package

[naive pawn]

compiling doesn't have anything to do with vscode

that's done in unity

[ivory bobcat]

I'm assuming that's a typo and that you're on the latest LTS. Are you using Odin?

[naive pawn]

why would you assume that's a typo...

[thorn holly]

Why would you assume that out of curiosity

[ivory bobcat]

An Odin known issue had been reported with the current LTS if you are https://issuetracker.unity3d.com/issues/the-inspector-breaks-when-serializing-custom-odininspector-component

[thorn holly]

I don’t know if this goes for everyone else but I usually don’t update to LTS once I start a project unless there’s some super useful feature added

So if they started their project before LTS came out they probably didn’t update

[ivory bobcat]

The version they had stated was
6000.0.63f1 where's the current LTS is
6000.6.3f1

[naive pawn]

the current LTS stream is 6000.3

6000.5 is in alpha, i don't think 6000.6 exists yet

i mean, either it's that and the copied the incorrect version (which, it's shown at the top of the editor, so i honestly kind of doubt)
or it's a different issue
i don't see why you'd assume the first one, it doesn't seem overly more likely to me

[ivory bobcat]

Ah, you're right. It's a bit early here. Wasn't even able to properly read the image I had posted

[mild furnace]

regardless, trying to compile or enter play mode while vscode is open takes an obscene amount of time 1-2 minutes.
when vscode is closed, it takes only a few seconds

[ivory bobcat]

Pretty sure that isn't the issue

[mild furnace]

It seems to be an issue with the package, all the other software I'm using runs fine

[naive pawn]

to make sure we're on the same page, you're saying there's an issue with the visual studio package in unity?

[mild furnace]

Thats what it seems like,
i've tried disabling most features in vscode extensions to no avail

[naive pawn]

somewhat of a hunch, does it fix itself if you restart unity or your computer?

[mild furnace]

Nah, I've also clean reinstalled unity and vscode, cleared caches etc.
Task manager shows vscode spiking heavily on cpu every time I click back into the unity editor or try to enter play mode

So I assume the unity package is doing something weird, maybe rescanning the entire project or trying to sync up with vscode

Been working on this project since late 2021 and had no issues, but vscode has been gradually auto updating with unwanted features

[thorn holly]

May I ask why you use vs code over vs community?

[mild furnace]

Because it used to be lightweight and user friendly

[naive pawn]

have you tried disabling all extensions? (in vscode)

[thorn holly]

Fair nuff

[nimble apex]

vsc is basically a text editor , ofc its better than notepad , but yeah , u should know text editor is lightweight right?
were just making it behaving like IDE by stuffing it with plugins

[mild furnace]

Yeah, last I checked it was a process from the c# dev kit causing performance issues

With all disabled, no issues but I dont get intellisense or tools to navigate the project

[nimble apex]

but no matter what coding tools u use , if its configured and can detect unity API, its the good IDE , the rest is about ur own skill

[mild furnace]

The main reason I'm here is that this tool has suddenly become unusable after 3-4 years of constant use

[naive pawn]

what version of unity/visual studio extension?

[mild furnace]

Process explorer is pointing me to language server

Unity 2021.2.20f1, unity extension 1.2.0

Thinking I may just run the extension version way back after clean uninstall

[naive pawn]

if you have newer unity versions installed, have you tried with those? do those also show a significant different when linked to vscode

[ivory bobcat]

Just for clarity, what you're experiencing now.. is still related to what you've had issues with in the past? Is this occurring only if you had edited the script or simply from alt tabbing? An empty project? I'm pretty sure you're aware already but unless you've set up assembly definitions: when you make changes to code, it and all of it's dependencies (including imported assets) are recompiled unless someone had set them up (some third party assets have not)

[mild furnace]

Same issue yeah.
The cpu spikes still occur when alt tabbing after no edits but are much worse when I do make changes.
I havent tried an empty project. Just tested on a small unity 6 project, same issue. Its actually lagging my whole pc so discord push-to-talk sounds wont fire.

[steel warren]

Are there people here who can write scripts well in unity in C#? I'm just wondering where you learned this and how, I really ask a knowledgeable person to answer. I know the basics of C#, but I'm very far from writing scripts and don't know where to learn it. YouTube is bullshit, so is gpt, and I'm not aware of any normal websites. Thus, depression arises due to a simple misunderstanding of where to study.🙏

being good at programming involves both knowledge and experience
a lot of experience can substitute a small lack of knowledge and vice versa, experience can help you get more knowledge and vice versa

there are many good resources out there for programming - for c#, there are some pinned in this channel
but playing around to really understand code and be able to internalize that helps a lot

there are plenty of resources for that basic "understand logic" part, like ted-ed's think like a coder series

[rocky canyon]

🖐️ I code pretty decent.. I'm at the point i can basically do anything I want to build.. ⚠️ It may not be the best way, but i'll make it Happn Capn.. I can always go back and fix and refactor it later (that's a secret, it helps me learn new things to refactor bad things)...

but i'm self taught.. just practicing and building out little systems here and there..
https://www.youtube.com/playlist?list=PLFt_AvWsXl0fnA91TcmkRyhhixX9CO3Lw i used this playlist when i got started.. it really helped me get an idea of how the coding worked.. (basically you start with variables and methods and go from there) and then learning to assign things.. https://unity.huh.how/ this page has useful information like how to assign variables correctly...

beyond that jus check the pinned comments to find resources and you'll have the company men suggest using unity learn resources.. from their website

anyway best of luck.. happy coding 🍀
TLDR: learn everywhere and build any and everything... just jump in and start familiarizing yourself with the editor and jumping to code and back
and after that just start

[naive pawn]

(in general) there's 3 major parts to programming:

• Language - The syntax, structure, and paradigm of each language
• Library - The interfaces and utilities that each environment or toolset provides
• Logic - The algorithms to do work at runtime

Logic is almost completely transferrable between each language and environment, you just have to learn the specific Language and Library that you're using
Language is also shared quite a bit between languages

of course, learning 1 part at a time is easier than learning everything at once, which is why tools like scratch or code.org are popular as coding courses for beginners, especially kids, because it only focuses on the Logic aspect

there's also that ^

i only knew things like html, javascript, and a little php when i came across Unity..
I personally learned c# and Unity hand-in-hand.. not sure any of those past langauges really helped but I picked it up pretty quickly.. im a quick learner anyways.. it just takes a minute to really solidify what i've learned

[naive pawn]

i learned them alongside each other, but i already knew how to program in general beforehand in js and java

[rocky canyon]

been building and scripting in Unity for 4 years now.. and If I had to write a Command / Console type script today I couldn't do it.. I'd have to google it and learn how 😅

[naive pawn]

it always helps to know things before hand

the first language you learn is always the hardest lol

[rocky canyon]

thats because like he pointed out early theres different pieces of coding.. and once you figure out how scripting works in general the language you're writing in is just about learning the new syntax and stuff

html didn't do me any favors tho 🤣

except already knowing how to use rich-text

[steel warren]

Well, it's just that you're smart and I'm not. My first language is C#, and at first I only watched videos on the YouTube channel +-110, but these are THE BASICS. And I've already searched on various websites and channels, but I still haven't figured out if they're normal or not, so I decided to write here.

[steel warren]

Well, yes, if you know 1 language well, then everything is easier there.

[rocky canyon]

if you use unity learn it'll guide you through piecing together your first scripts..

it'll get easier with time..

you sorta have to wait for that "eureka" moment.. when it all decides to click in your head..

but keep experimenting up until then.. and even afterwards

instead of "give me all the basics" work through things until you get stuck. or until you come across something you don't quite understand.. and then come back here and ask that question.. or to explain..

thats the best use of this discord ☝️

[steel warren]

Well, it happens, but the main thing is to know how and what to do, and everything else fades into the background and gets forgotten.

[steel warren]

I'm sorry if I'm distracting you. Could you please tell me which courses I need to take in unity learn? I would just say that there are a lot of them and it's not very clear where to start.

[naive pawn]

beginner scripting would be a good start, it's linked in the pinned message

though if you have some experience with code in general, there'll probably be some parts you can skip over or speed through

[nocturne kayak]

Personnally i would just learn C# basics and try to create my own thing , so You learn how to search and find information on the internet.

[naive pawn]

well, you still need to learn how to interface with unity with messages and serialized fields for example

[nocturne kayak]

yes ofc !

[remote spade]

Im not a knowledgeable person but i started with the microsoft c# tutorial ( https://learn.microsoft.com/it-it/shows/csharp-for-beginners/ ) and then i tried to do random projects with c# after that i got to unity where i started by watching a tutorial just to understand where to look and now i just use the documentation to understand what i dont

[steel warren]

I know the basics of C# but I didn't know what to do next, and then someone gave me some advice.

[nocturne kayak]

Same :)

[remote spade]

Oh and if you dont know what to do for like a “project” ask ai for ideas

[steel warren]

Thank you for your advice.

[remote spade]

Np i like to help

[deft loom]

hey folks im following a tutorial on getting a simple character controller up and working. I made the input map, write the requisite code in a player controller script, and now I just added a Player Input component to my player. I changed behavior to Invoke Unity Events, and then under Events > Gameplay > I added my player controller to the Move CallbackContext. Then in the tutorial the guy clicks the "No Function" dropdown and adds a callback function that we added in our player controller (which I verified does exist) - but for some reason I don't see any options. What could the issue be?

[slender nymph]

https://unity.huh.how/unity-events/incorrect-assignment

[deft loom]

Thanks! That got me a bit further, though now I don't see the "OnMove" function from the player controller. What am I missing now?

[slender nymph]

is it public and is the parameter the correct type?

also why would you subscribe "OnMove" to the Device Lost Event?

[deft loom]

oh whoops I meant to add it to the move under the gameplay dropdown, selected the wrong one without realizing it. Its there now, thank you!

[hexed swan]

hello i'm trying to make a supposedly simple script to create an image from a camera but it gives me this error when i name it

[deft loom]

There's so many moving parts its overwhelming. Idk how I would even begin going about learning this stuff without a step-by-step tutorial. It doesn't feel like simply learning a new programming language or web framework where the path to start making stuff is fairly linear

[slender nymph]

you likely have compile errors

[hexed swan]

if gives me that message even if its a newly created script with nothing in it, if i name it

[slender nymph]

probably because you have compile errors

[slender nymph]

have you considered that you might have compile errors

[hexed swan]

how can i have a compile error if there is nothing in it

[slender nymph]

i didn't say "a compile error in that specific file" i said "compile errors". any compile error prevents all of your code from being compiled

[hexed swan]

this?

[slender nymph]

yes, that is a compile error. you have two methods with the exact same signature. and if you didn't see red underlines in your code when writing that bit, then you need to get your IDE configured 👇

[stone oar]

heyo, question: how to detect when character controller is moving upwards? what's the best method?

[slender nymph]

your own code is what moves it upwards, yes? so when whatever code you have that moves it has a positive upward velocity then you know it is moving upwards

[stone oar]

currently im thinking about recording position a frame before and then comparing

[stone oar]

well the thing is - it doesnt do that

[slender nymph]

how

[stone oar]

sometimes velocity.y will be negative when moving too fast upwards

no idea why, movement in playmode works well

[slender nymph]

show your actual code then

[stone oar]

can't really tell you without pasting the entire code

[slender nymph]

so right before you call player.Move on line 175 you can check if it is moving upwards because at that point your totalVelocity is what is being used to control whether it moves upward or not

[stone oar]

with Debug.Log(totalVelocity.y); and moving up and down, stopping sometimes and so on. can't really tell when it's good to check for upward movement when digits are going this crazy

[floral garden]

what do you want to do ?

[stone oar]

well detect when player moves upwards, but i only really need it for slopes so i just reused the code for detecting when player is on the slope to determine if player is moving up the slope or not

[mortal jasper]

You should normalize

So you get 1 0 or -1

[midnight tree]

Show the parameter of these changes in the inspector?

[stone oar]

i forgot to mention that i already fixed the problem here and that the solution i mentioned is the one that worked for me

[rain solar]

anyone have a resource for procedural grass? when i looked it up its only blender tutorials, which is clearly not procedural

[solar hill]

Which procedural grass video did you watch that wasnt procedural?

[rain solar]

every single video involving blender

[solar hill]

Im seeing multitude of procedural grass videos and pretty much 100% of the ones that claim to be procedural... are exactly that.

Plus it doesnt take much to recreate a blender node set up in the shadergraph, most nodes already share a lot of functionality

[surreal shore]

what do i do i cant open any projects and i have tried redownloading it multiple times

[verbal dome]

What does that mean exactly, do you want individual procedural grass blades? Or procedurally placed grass? Or what

[rain solar]

grass that isnt drawn on when a map is made

drawn on by hand

[obsidian grotto]

is there any better documentation for onParticleTrigger?

or even examples, looked a bit online and it seems like all discussions related to it are like 5 years old at least lol

[verbal dome]

I don't think the particle system has changed in the past 5 years

[verbal dome]

What's the issue with your code or the unity documentation?

[obsidian grotto]

I just can't really figure out anything the function does lol. Like pretty much all I know is that it's a callback function that is called when the trigger is triggered, but aside from that there's no information on getting what it collided with, what system the particle came from, etc.

looked around a bit more and not even sure if the triggers will really work tbh so may just try to do it with regular collisions

that said the reason I wanted to use triggers as opposed to regular colliders was so that it didn't have the physics associated with a collider..

any way to achieve that?

[verbal dome]

OnParticleCollision docs say this:

This message is sent to scripts attached to Particle Systems and to the Collider that was hit.
So maybe it's the same for OnParticleTrigger? The doc is a bit lacking, yes

[obsidian grotto]

I'll give that a shot!

[verbal dome]

Let me know if it's called on the object that has the trigger collider

If not, then idk how to check which one you hit

[obsidian grotto]

also the reason I said I don't think it'll work is that apparently you need to give it a list of things it can collide with but I'm doing this as a prefab so yeahh

[verbal dome]

What do you need to happen when a particle collides/hits a trigger?

[obsidian grotto]

I just want to deal some damage to a player/enemy

[verbal dome]

Should the particle disappear after that?

[obsidian grotto]

so pretty much grab the game object it collides with, check if it's the player, if it is then we also check what kind of particle we are and how much damage should be delt, then from the player grab a certain script and call the damage method

[obsidian grotto]

nope it should persist

[verbal dome]

Then yeah particle collisions (non trigger) probably won't do since it would stop/bounce off

Also depends what kinda colliders you want to use on the enemy

[obsidian grotto]

it's just a regular box collider 2d

someone on stackoverflow shared this and I think it may work?

// Source - https://stackoverflow.com/a

// Retrieved 2025-12-28, License - CC BY-SA 4.0

private void OnParticleTrigger()  
    {

        //Get all particles that entered a box collider
        List<ParticleSystem.Particle> enteredParticles = new List<ParticleSystem.Particle>();
        int enterCount = waterPS.GetTriggerParticles(ParticleSystemTriggerEventType.Enter, enteredParticles);

        //Get all fires
        GameObject[] fires = GameObject.FindGameObjectsWithTag("Fire");

        foreach (ParticleSystem.Particle particle in enteredParticles)
        {
            for (int i = 0; i < fires.Length; i++)
            {
                Collider collider = fires[i].GetComponent<Collider>();
                if (collider.bounds.Contains(particle.position))
                {
                    fires[i].GetComponent<Fire>().Damage();
                }
            }
        }
    }

just seems kinda jank lmao

[verbal dome]

That's a super brute force way to do it

[grand snow]

good god if that does a find by tag each time a particle enters a trigger 😐

[verbal dome]

I don't think this works with 2D physics

Are you making a bullet hell game or something?

[obsidian grotto]

nah it'll be a regular amount of particles sending off triggers

like 10 enemies attacking you at once at most

[verbal dome]

How many particles we talking about

~1 per enemy?

[obsidian grotto]

yep

and attacking like once per second

[verbal dome]

Using particle collisions for gameplay logic (like damage) feels yucky to me

I'd just do some raycasts or use rigidbodies

[obsidian grotto]

fair enough 😭 high key it's for a game jam and I wanna up my particle game lol

also my thought process was that I'd make a bunch of particle system prefabs and slap them into enemy prefabs and stuff would work like that

but ig now that I think about it some more the logic should be fairly straightforward to do smth similar for rigidbodies

[verbal dome]

You can always have particle systems on the object that has the rigidbody

[obsidian grotto]

oh true!

will prolly go with that lol

yo!
Im looking for resources regarding mouse drag and drop in 3d, but making it feel magnetic/springy. So not just following EXACT mouseposition or raycast.
No luck yet looking on google/youtube.
thanks! 🙂

[frosty hound]

There's no off topic here, thanks.

[cosmic dagger]

look for pointer events tutorials, or google: pointer events for 3d objects unity . . .

[grand snow]

You can utilize Vector2 MoveTowards along with the event system point drag events (https://docs.unity3d.com/Packages/com.unity.ugui@1.0/api/UnityEngine.EventSystems.IDragHandler.html)

3D colliders + PhysicsRaycaster also required

What's wrong with my camera?Am I rotating the pivot the wrong way?

This is my script

using System.Collections;
using Unity.Cinemachine;
using Unity.VisualScripting;
using UnityEngine;
using UnityEngine.InputSystem;

//-----Script body-----\\
public class CameraFollow : MonoBehaviour
{
    //-----Public Variables-----\\
    public GameObject Pivot;

    
    [Range(0, 10)]
    public float TurnSpeed;

    //-----Private Variables-----\\
    private PlayerInputs PlayerInputs;

    private InputAction MouseDelta;

    private void Awake()
    {
        transform.position = Pivot.transform.position - new Vector3(0, 0, -10);
        transform.LookAt(Pivot.transform.position);

        PlayerInputs = new PlayerInputs { };

    }

    private void OnEnable()
    {
        MouseDelta = PlayerInputs.Default.MouseDelta;
        MouseDelta.Enable();

    }

    private void OnDisable()
    {
        MouseDelta.Disable();
    }

    void Update()
    {
        if (Pivot != null && Mouse.current.rightButton.isPressed)
        {
            CameraOrbit();
        }
    }

    private void CameraOrbit()
    {
        Vector2 Axis = MouseDelta.ReadValue<Vector2>();
        float xAxis = Axis.x * TurnSpeed;
        float yAxis = Axis.y * TurnSpeed;

        Pivot.transform.Rotate(xAxis,yAxis,0);
    }
}```

I have problems at the CameraOrbit()

I think im rotating it wrong

Could someone tell me why my camera is drunk?

(note the pivot is supposed to move up when I move the mouse up, right when right,...)

I did search this

On google

But no one had a drunk rotation to their camera pivot

Its just mine

[verbal dome]

A more robust way of doing rotations like this is to keep track of the angles manually (float xAngle, yAngle). Modify those according to the input and then make a new rotation (with Quaternion.Euler(xAngle, yAngle, 0) for example) and assign that to the transform rotation/localRotation

[verbal swift]

How do I make the horizontal inputs stronger than vertical ones

[grand snow]

scale the read values to achieve the effect

e.g. * new Vector2(1.25f, 1f)

[verbal swift]

Its in 3d and orientation dependant but I wish I could use a vector2 😭

Im trying to make it so the A and D keys add more force than W and S while sliding

[grand snow]

Erm no the input you read is 2d so you adjust this

are you confused with something else or using some pre made movement?

[rocky canyon]

one approach is using a multiplier on the horizontal input value

just like scaling like rob said ^

that way ur vertical input would be like -1, 1 for example and the horizontal would max out at -1.25 and 1.25

[rich adder]

also if you're using new input system they have it as well

[grand snow]

^ This would mean you need different actions active depending on the game state

Id personally just scale input where you process it and know the players state/movement type

[rich adder]

hmm I just found it useful when dealing with controller axis vs mouse, my mouse always tended to be more sensitive and had to scale it back 0.5f iirc

[remote spade]

in this case how do i get the sprite renderer in the player/sprite gameobject

[naive pawn]

from the floor?

[remote spade]

player

[naive pawn]

use a serialized reference

[slender nymph]

https://unity.huh.how/references/serializing-component-references

[remote spade]

no i mean how can i get them trough script

GameObject playerobj = GameObject.Find("Player");
SpriteRenderer sr = playerobj.GetComponent<SpriteRenderer>();

[slender nymph]

use a serialized reference

then you don't need to use Find (also why would you be using Find("Player") from the player?

[remote spade]

its not from the player

[slender nymph]

when asked you said it was from the player

[remote spade]

the sprite under the player yes

not from the player

[slender nymph]

when Chris asked "from the floor?" that was in reference to where you are trying to do this from, not where the sprite is that you are trying to get

[remote spade]

im trying to do it from a object that is not Instantiate yet

[slender nymph]

https://unity.huh.how/references/prefabs-referencing-components

[naive pawn]

why do you need to access the sprite directly from another object anyways

[naive pawn]

sounds very much like an x/y problem to me

in general you'd just tell the player that something happened and then the player would manage its own graphics or whatever

[remote spade]

a what?

[naive pawn]

an x/y problem

i linked to an article that explains what that is

[slender nymph]

-# hint: blue text means it is a clickable link

[remote spade]

yh probably

[rich adder]

so instead, "What’s the best way to solve X?"

[slender nymph]

if even you think it is an xy problem after reading that page, then considering heeding the advice on that page and ask about your actual intention

[remote spade]

i cant articulate that in english

[naive pawn]

articulate it in your native language as pass it through google translate then, perhaps

[rich adder]

you seem to do fine so far, try.. what you actually want to achieve ?

[remote spade]

i want to make the player shoot a arrow, if the player looks at the left side the arrow should have negative speed for it to go to the left, but idk how to change the speed of the arrow depending on the direction the player is facing

[slender nymph]

how do you determine which direction the player faces

also your arrow doesn't need a reference to the sprite to determine that, your player should just instantiate it facing the right direction in the first place

[remote spade]

i just flip the sprite if the horizontal input is negative

[slender nymph]

then it's just a matter of moving it forward in the direction the arrow is facing

[slender nymph]

you might want to consider rotating the entire player object 180 degrees instead of flipping the sprite, that way all parts of the player will always face the correct direction and you won't need to always check what direction the sprite is facing when attempting to do certain things that depend on the direction the player faces

[remote spade]

andd how do i rotate the whole thing

[slender nymph]

well that's easily googleable, but it's literally just transform.Rotate or assign to the transform.rotation property

[remote spade]

oke thanks

[remote spade]

and sorry if i was annoying

[naive pawn]

you could also use scaling to flip (not saying that's better than rotation, just another option)

[stark helm]

I did try doing that, but now my camera is a little less drunk

Its like

Weird, I looked tutorials with cameras, but mine is still drunk

[slender nymph]

show your code

O so that's why I cant rotate

Do I use something else?

[naive pawn]

if you want to set euler angles, that would be setting eulerAngles, or creating a Quaternion using Quaternion.Euler

[naive pawn]

btw, mousedelta is already per-frame. you should not use deltaTime for it

[stark helm]

Ok thanks Chris

I will test now

Chris

I messed up

wait

I will switch the angles

Because its weird

YES

IT WORKS

but why are the y and x inversed...?

well it doesnt matter

Thanks Chris

You helped me complete this after 4 days of useless googling

You are a pro

[polar marsh]

Learning C# for a week now learned all the basics and some advance stuff but parameters are getting hard on me

[floral garden]

you mean function parameter ?

[polar marsh]

Yes

[wintry quarry]

parameters are part of the basics

[floral garden]

there is a lot to learn on it

[polar marsh]

Hmm maybe I didn't understand them correctly or it's just my brain

[naive pawn]

is there a specific question you have or a detail you need help with?

[jaunty wing]

private void Roll(InputAction.CallbackContext context)
{
if (context.performed)
{
action.Roll();
print("ROLL");
}
}

how would I go about stopping an action from preforming multiple times when i press the keybind?

[grand snow]

Check the phase too

Or you subscribe to the correct event for the action in the first place

[naive pawn]

that's what .performed is, no?

[frosty hound]

Performed is called twice. You need to check the phase to get a single call.

[naive pawn]

isn't performed, well, the phase

it's started -> performed -> canceled, right? and the timing diagram for button type with no interaction shows performed only occuring once

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.17/manual/Interactions.html#predefined-interactions

[frosty hound]

Right, I'm confusing myself I think

[balmy vortex]

hi is there a list somewhere of common performance optimizations you can apply in most unity projects?

or does smth like that not exist yet

[plush palm]

I took a long break from coding and came back to Unity not suggesting types "int, floats, GameObject" why?

uhm i need help with an error

[solar hill]

Damn man dont spill it out all at once

[gilded cypress]

ima take a picture and show you

it must be easy

can we fix it??

[rich adder]

looks like you have two Start() methods in the same class

[gilded cypress]

uhh what do you mean

[rich adder]

https://learn.microsoft.com/en-us/shows/csharp-fundamentals-for-absolute-beginners/

[gilded cypress]

just tell me how to fix it wwith out videos

[plush palm]

He did tell you how

[teal viper]

How much are you paying?

[plush palm]

You're calling Start() twice in the same script

[gilded cypress]

im good

oh

[rich adder]

not calling, defined
(you can call methods as many times as you please)

[fickle plume]

@gilded cypress This is a learning community, if you are not here to learn, you're in the wrong place.

[gilded cypress]

im making a vr game

my friends expect it soon

i mean really soon

[rich adder]

tell you're friends you have no clue how to csharp

and should learn its basics

[solar hill]

Does it involve apes of some kind

[teal viper]

So they have to wait

[solar hill]

I bet it does

[gilded cypress]

rude 🙁

@gilded cypress There's no off-topic here either. #📖┃code-of-conduct Focus on the learning.

[solar hill]

Oh nvm they litterally have gorilla tag in their name

[gilded cypress]

uhh yeah i make gtag content

plus games

[solar hill]

Do you want the brace to be under the for loop?

You on vs?

[plush palm]

Yeah I do, I've checked my settings. I'm not sure why it's auto completing to be the same line. I am on VS

[solar hill]

Did you restart the editor?

[plush palm]

Yeah I have 🙁

[solar hill]

You can try doing ctrl + k, i think that reformats a document in visual studio

Put your cursor down anywhere inside of the file first

[plush palm]

I think I just fixed it, but just turning off the auto complete braces

Yeah that fixed it, since I hit enter and it creates them on the line i like, thanks anyways Kuzmo 😛

[fickle plume]

I think they fall in place when you press enter, it might expect further input to format

or when closing bracket, then reformat triggers

[solar hill]

At least its not copilot magically enabling itself every time you launch vs code

[plush palm]

Sadly it didn't reformat on closing bracket either

[rich adder]

sad but true

[hearty marsh]

Beginner dev here, how would I be best to go about creating a hero collector style game similar to Star Wars Galaxy of Heroes, Marvel Strike Force, Raid Shadow Legends? Images attached for the sort of game. Battle screen, squad select screen, and individual character screen

[rich adder]

in what sense?

you want someone to explain the entire game system?

[hearty marsh]

Just trying to figure out where I would start to make a game like that, as I really have no clue where to start

Hello 🙂

Creating an OS system inside a game hehe

Well, its a simulator.
OS/hacking simulator to be direct
With nice format supportive text editor and whole bunch of other features too. Drag and drop to desktop also, file explorer etc for apps, files, folders.
Glad its finally in a working state.

Worked hard

[teal viper]

Whatever you like more or plan to work on in the future.

[drifting cosmos]

Is giving an object a reference an expensive thing like when an object spawns calling a function on it to set a reference

I have like 40 objects that I could give a reference to but i don't need to if it will be to expensive on the server

[frosty hound]

If you have to give something a reference, then you have to do it.

You can't really avoid it if you're spawning something and then passing info along to it.

[wintry dew]

is there any way to get rid of this warning? i dont have access to like unity source code so i dont know how to make the pro builder stuff "serializable"

[sour fulcrum]

i don't believe so

[twin pivot]

You ignore it like the rest of us

[crystal lake]

what IDE do i choose?

i used Visual Studio few times but couldn't adapt in it

[verbal dome]

From my experience Visual Studio Code is the lightest, Rider has way more features but has worse performance

Rider has a free license for non-commercial projects

What was the issue with Visual Studio?

(Note that VS and VS Code are different programs)

[crystal lake]

forgot that, yeah i used VSC

[crystal lake]

projects hierarchy i think

basically starting a project was quite difficult

managing folders and stuff

[verbal dome]

Hmm, well I do project organization on the unity side, not in the IDE, so can't comment on that

Doesn't sound like an IDE-specific issue

[crystal lake]

you're right, it was the problem when i used to make a game on python

[verbal dome]

Ah, well that shouldn't be an issue with unity

You can create folders and scripts in the unity editor's Project window

And move them around

[crystal lake]

yeah yeah, thanks

[verbal dome]

I started with VS Code and later moved to Rider, it was handy because Rider lets you import VS Code keymappings so it felt familiar from the get go

[crystal lake]

okay i'll keep that in mind

[naive pawn]

this is intellicode, not intellisense/autoocmplete/snippets. it's AI, i don't think you can really control its output

[naive pawn]

you can uninstall copilot

[frail hawk]

it can be turned off on the bottom it says snooze, press it a few times and it will shut up

i highly recommend to turn it off, especially for beginners, it is doing too much of the job

it doesnt work

[verbal dome]

Did you add this component to an object?

[latent sorrel]

i think so

[verbal dome]

If yes, check your console for input manager errors (or other errors)

[latent sorrel]

thanks it works now but i dont now how

[frail hawk]

important: your script and class name differ

[verbal dome]

Next time it happens, open the console in unity and look for errors

[mortal jasper]

What is the bad thing?

[frail hawk]

the bad thing is this should not work

[verbal dome]

I think that requirement was removed in newer unity versions

[teal viper]

Still, a good idea to keep them consistent.

[verbal dome]

Mhm

[frail hawk]

ok if they really removed that requirement, then it was a bad feature

[latent sorrel]

@verbal dome but now i fell throw the ground

[verbal dome]

Well the code you showed is not for physical movement anyway

If you want physics, use a rigidbody, make sure things have colliders and move the object with rigidbody methods, not transform

[stark helm]

Quick Question, how do I get the cursor's position on the screen using the new input system?

[stark helm]

Is this a good place to learn Unity?

[verbal dome]

So I have heard

[glass berry]

How can I make when the player click e te door open with animation

[real thunder]

How do you initialize a new struct with values in one string? Do I have to make a constructor? Not sure I use right terms, here are snippets

public struct TargetAndTeam
    {
        public Transform trans;
        public int team;
    }
//then somehwere else
  targets.Add(new TargetAndTeam(target, team));

what am looking for

[verbal dome]

You can do new TargetAndTeam { trans = target, team = team }

Without having to make a constructor

(you mean in one line, not one string)

[real thunder]

yeah thanks, I had a feeling I was doing that without a constructor but somehow googling didn't help

[verbal dome]

It's called an object initializer

I think

[latent sorrel]

Sorry that i need your help so often, but is playerController the same as CharacterController

[verbal dome]

No, playerController is not a built-in thing in unity

Probably a custom class from whatever tutorial you are watching/reading

CharacterController is a built-in component

[latent sorrel]

Unity says that the cameraTransform of the PlayerController has not been assinged, what should i do now?

[naive pawn]

assign it

[latent sorrel]

how

[naive pawn]

drag something into that slot in the inspector

[latent sorrel]

but i dont find PlayerControll in the inspector

i found it sorry, my bad

[naive pawn]

have you gone through unity essentials in unity learn

[frail hawk]

first you would determine wheter you are in the range to open door or not. this can be done in many ways for example with a raycast or a ontriggerenter. then you need the player input and finally you would trigger the animation.

[stark helm]

What method would I use to prevent the camera going through objects?

Does anyone have any ideas?

[stark helm]

What is a PlayerControll?

[stark helm]

What?Sorry to ping, what is CharacterController?

And what does it do?

[real thunder]

it's like RigidBody but easier to control yet kidna ignore most physic interactions

[ivory bobcat]

https://docs.unity3d.com/6000.3/Documentation/ScriptReference/CharacterController.html

[ivory bobcat]

https://docs.unity3d.com/6000.3/Documentation/Manual/class-CharacterController.html

The Character Controller is mainly used for third-person or first-person player control that does not make use of Rigidbody physics.

[frail hawk]

a collider on the camera

[verbal dome]

A collider alone wont do anything really

I bet cinemachine has something for camera collisions though?

[frail hawk]

cm is always the number one choice unless you want something really simple or prototype

[gilded badge]

What VSCode extensions should I install for Unity 2D anc C#?

my tutorial has autocompletion on gameObject and I don't, is that because I am missing an extension?

[teal viper]

There's no such thing as unity 2d. You're probably thinking of the 2d template, which has nothing to do with code.

thanks that wiorked

[ancient nimbus]

how can i smooth that out?

    if (PlayerRigidBody.linearVelocity.y > 0)
    {
        PlayerRigidBody.rotation = FlapRotation;
    } else
        PlayerRigidBody.rotation = -FlapRotation;

[nocturne kayak]

Lerp maybe ?

[ancient nimbus]

i'll try that, thanks

[nocturne kayak]

No problem :)

[frail hawk]

and do it the right way, when it comes to lerping there are many ways on how you shouldnt do it

[ancient nimbus]

omg i'm so happy, i'm making a working script with no tutorial, FINALLYY

[naive pawn]

have some interpolation between them instead of snapping to the rotation, for example with lerp or movetowards or smoothdamp or any other interpolation function

wow my connection is terrible right now lmao

[ancient nimbus]

i think i'm gonna make a public float called LerpSpeed and multiply it by time.delta time in the (a, b, t) T

[naive pawn]

that's called wrong lerp and you should not do that

https://unity.huh.how/lerp/wrong-lerp

[ancient nimbus]

i read thru that but i don't get it

[verbal dome]

@nocturne kayak FYI, Slerp is a better choice for rotations instead of Lerp

Especially when the angle difference is large

[nocturne kayak]

Oh okay, I didn't know that.

[nocturne kayak]

thank you

[ancient nimbus]

how can i use that?

[verbal dome]

Google and see example in the documentation

Quaternion.Slerp

[nocturne kayak]

So using the wrong LERP will result in fewer FPS than Lerp *

[naive pawn]

no

[verbal dome]

This isnt about lerp vs wrong lerp

And no

Ah chris mentioned it

[naive pawn]

wronglerp (compared to any lerp, including slerp) means your output is framerate-dependant and asymptotic

[ancient nimbus]

i'm not using quaternions i'm using floats tho

[verbal dome]

Oh its 2D

[ancient nimbus]

yup

[verbal dome]

Mathf.LerpAngle

[ivory bobcat]

Wrong lerp moves towards the target value at some fraction
(important:) but never really gets there

[verbal dome]

Wraps around 360 degrees correctly

[nocturne kayak]

Oh okay i get it now thanks y'all

[verbal dome]

You probably want to use MoveRotation instead of rotatuon though, otherwise interpolation breaks

If you use that

At least thats how it works for 3D rigidbody... Think its the same in 2D

[ancient nimbus]

yup but the thing tho, is that it's not smooth

[ancient nimbus]

yup

but is it possible to lerp the moverotation?

or tho slerp or whatever

[verbal dome]

Yes, use the current rotation as the input

Something like
rb.MoveRotation(Mathf.LerpAngle(rb.rotation, ...))

[ancient nimbus]

PlayerRigidBody.MoveRotation(Mathf.Lerp(PlayerRigidBody.rotation, FlapRotation, FlapRotationLerpSpeed * Time.deltaTime);

oh lerpangle right

alright lets test dis

[ivory bobcat]

Or use some animation curve for the third parameter to modify the rate

[verbal dome]

Oh true these are predefined values

I was thinking the classic lerp(current, end, t)

I mean both work but anim curve gives more control

[ancient nimbus]

amazing yayy

thanks guys

[ivory bobcat]

I feel that wrong lerp is quite too fast and it never really getting there (to the target value) deters me from using it.

[verbal dome]

Can combine it with a MoveTowards with a tiny value to make sure it reaches the end

But yeah the "better" lerp isn't hard to implement anyway

[naive pawn]

this is also wrong lerp

[nocturne kayak]

Do you have any idea why i have 30 fps when i'am using lerp to move a cube ? **{
public GameObject Cube ;
public Transform PointB;
public Vector3 startpos;

public float duree = 15f ;
public float elapsedTime = 0f;
private void Awake()
{
    startpos = Cube.transform.position;
}

void Update()
{
 if (elapsedTime < duree)
 {
    elapsedTime += Time.deltaTime;
        float t = elapsedTime / duree;
        transform.position = Vector3.Lerp(startpos, PointB.position, t);
    }
}

}
**

[naive pawn]

those 2 things are kinda unrelated

[ancient nimbus]

whatever it's not even that noticeable

[nocturne kayak]

oh ?

[naive pawn]

the change can be noticable if your fps changes

why would they be related

[nocturne kayak]

its only dropping when the cube is moving

[naive pawn]

to be clear - wronglerp does not make it jittery or whatever. that's not something you're gonna notice
wronglerp means that the behavior is inconsistent because it's framerate-dependant, and that the value will asymptote.

[ancient nimbus]

that's weird because i put time.delta time

[naive pawn]

there's so many things it could be
you haven't given any info as to what it might be
if it's an actual perf issue, use the profiler
but just moving a position isn't going to be outrageously expensive

[naive pawn]

just including deltaTime doesn't make something automatically framerate-independant, you have to use it correctly. in the case of wrong lerp, it is not being used correctly
