[marble halo]

A switch wouldnt need health

Basically like these things from ocarina of time

[heady iris]

it doesn't mean the object has health

it just means the object can be hit

[vagrant blade]

You wouldn't make health a part of the interface. You would create something like IDamageable

And then handle the OnDamage function uniquely

[marble halo]

Ah ok

[simple egret]

You can ignore any parameter you're passing, in the switch implementation
Makes me think of that "adding helicopters in game dev" meme

[marble halo]

Ah interesting

Just thought id ask

So like for an enemy OnDamage would have an int amount

[heady iris]

i usually wind up making a Damage struct/class

it might contain a list of kinds of damage

or just literally be

public struct Damage {
  public float amount;
}

if I'm not quite sure what I'll need yet

[ashen yoke]

yes struct is best

no allocations

[heady iris]

YAGNI -- You Ain't Gonna Need It -- suggests you just make it a float until we change it later

but it's not much extra work to just use the struct from the start

[simple egret]

This, so if you ever need to add stuff later on, no need to go through all call sites to add a parameter

[ashen yoke]

only problem is capturing bunch of modifiers later

[gray mural]

Why does prefab that I Instantiate stay in the Scene, when Game is finished?

or is it always so?

[ashen yoke]

how do you instantiate it

[marble halo]

So if OnDamage(int amount) is in the interface does that mean everything that uses IDamage need an int for how much damage?

[ashen yoke]

at runtime?

[ashen yoke]

yes

interface is a contract

[gray mural]

TMP_Text newTextComponent = Instantiate(textComponentPrefab, textComponentsHolder.transform);

[ashen yoke]

"class is obligated to have this method verbatim"

[heady iris]

where do you do this

[marble halo]

Cause a switch like that wouldnt need the damage amount since theres no health

[gray mural]

private int textComponentIndex
{
    get => m_textComponentIndex;
    set
    {
        while (_textComponents.Count <= value)
        {
            TMP_Text newTextComponent = Instantiate(textComponentPrefab, textComponentsHolder.transform);
            _textComponents.Add(newTextComponent);
        }

        m_textComponentIndex = value;
        _textComponent = _textComponents[value];
    }
}

[marble halo]

but an enemy does

[ashen yoke]

then just dont use the parameter

[heady iris]

if this happens in the editor, then they will stick around

[gray mural]

in the editor?

[heady iris]

you're free to ignore parameters

[gray mural]

how to avoid it?

[ashen yoke]

looks like something is calling it outside of playmode

[heady iris]

Now, there is another option here: separate "damage" from "activation"

[gray mural]

everything in my script is being called outside of playmode actually

[ashen yoke]

@marble halo you can drop a parameter by using _

[heady iris]

You might do that if you have many different kinds of things you "activate"

[marble halo]

ah ok

[heady iris]

so maybe you have elecrtic arrows that do electric things

but!

i like the idea of keeping it all together. so electric arrows do electric damage and turn on electric objects

[simple egret]

Hell, you can even make interfaces "inherit" from others so their methods accumulate

[heady iris]

now there is harmony.

[ashen yoke]

do you have a guard with EditorApplication.playModeStateChanged ?

[heady iris]

hey, game idea is forming here...

wait, this is just bioshock

zap

[gray mural]

I do not use it if that's what you mean

[ashen yoke]

how do you guard it then

Application.isPlaying?

[gray mural]

what do you mean?

I have just written normal script as I always do

nothing special with Aplications in it

[ashen yoke]

you are writing scripts for edit mode

completely different semantics

[gray mural]

what does it mean?

I am writing my script as usually

[ashen yoke]

there are 2 modes, Edit mode and Play mode

for example if you instantiate a prefab in play mode with Instantiate it will work as you expect

if you do the same in editor you are creating a broken/incorrect instance

because while in edit mode the correct way is to use PrefabUtility.Instantiate...

there are a lot of cases like that

lots of things to keep track of

Destroy/DestroyImmidiate for example

[gray mural]

by default it's done in Play mode, right?

[ashen yoke]

what default

i asked you if you do it in play mode you said everything is outside of it

play mode is a state of unity editor

when you press the play button it switches to it

[gray mural]

oh, you mean that

[ashen yoke]

if youre doing editor tooling you have to use editor approach for things

and cleanly separate play/edit behaviors

if you mix them with ExecuteAlways for example

[gray mural]

Unity uses Play mode by default, right?

[ashen yoke]

i dont understand the question

default in what context

[gray mural]

wait, actually that was dumb question

[gray mural]

ok, so Play and Edit behaviours are seperated by default

[crimson atlas]

you can edit during play, however it won't stay after play is finished

whatever edits you do during play, it only affects the play session
everything goes back to what it was before you hit play

[gray mural]

it stays though

[ashen yoke]

that means its created outside of play mode

[crimson atlas]

well it might depend on what you're editing then
(i'm new here btw. asking questions mostly. lol)

[gray mural]

yes, my issue is that intantiated objects stay in Edit

[ashen yoke]

for example you have some Awake/OnEnable in a class with [ExecuteAlways]

[gray mural]

how can it even happen?

[gray mural]

I don't

[ashen yoke]

    [ExecuteAlways]
    [SelectionBase]
    public class Selectable 

[gray mural]

I see

how to avoid it?

[ashen yoke]

i dont think you can avoid it here

but you can modify your code accordingly

also i dont understand why you hid virtual methods

instead of overriding them

that should most likely break the whole thing

[gray mural]

you mean Awake and Start?

[ashen yoke]

yes

[heady iris]

i'm not sure how override vs. new behave with respect to unity messages

[gray mural]

why should I override them?

[ashen yoke]

so that base methods would be called

and your method would be called as well

[gray mural]

do I need them? 🤔

though maybe

[heady iris]

override doesn't mean that both methods get called...

[ashen yoke]

if event system operates on selectable directly, your new methods should not be called at all

[gray mural]

if you call base();

[heady iris]

ah, fair.

[crimson atlas]

pacman game, player collider, ghost collider
which one of the two should i mark for "is trigger"?
i know i can do in any of the two, but is there a best design?

[jaunty needle]

Guys why am I getting this NullReferenceException here?

    {
        stairSpawner.SpawnedStair += IncreaseStairCount;
    }

    {
        stairSpawner = FindObjectOfType<StairSpawner>();
    }

[gray mural]

no objects of this type

[ashen yoke]

a virtual method called on a base class will invoke the highest override first, a method that hides base method on a subclass will not be called if the base method is called on the base class

[simple egret]

OnEnable runs before Start

[heady iris]

right, I was just thrown off by how you said "your method would be called as well"

[jaunty needle]

Ah thank you

[heady iris]

it runs immediately after Awake, too

Awake and OnEnable are instant; Start is before the next Update

[simple egret]

Yeah, so you could move the code from Start to Awake here

[jaunty needle]

Yep that's what I did

[swift falcon]

Can anyone help me figure out this input system code?

[System.Serializable]
    public struct TextIARPair
    {
        public TMP_Text Text;
        public InputActionReference IAR;
    }

    [SerializeField] List<TextIARPair> _textIARPairList = new List<TextIARPair>();

    InputActionRebindingExtensions.RebindingOperation _rebindingOperation;
    InputControls _controls;

    void Start()
    {
        _controls = Get<PlayerInput>().Controls;

        string rebinds = PlayerPrefs.GetString("rebinds", string.Empty);
        if (string.IsNullOrEmpty(rebinds)
            return;        

        _controls.LoadBindingOverridesFromJson(rebinds);

        foreach (var pair in _textIARPairList)
          pair.Text.text = KeybindToText(pair.IAR);
    }

    public void Save()
    {
        string rebinds = _controls.SaveBindingOverridesAsJson();
        PlayerPrefs.SetString("rebinds", rebinds);
    }

    public void StartRebinding(InputActionReference iar)
    {
        TextIARPair pair = FindPair(iar); // Gets pair from list

        _controls.Disable();

        _rebindingOperation = iar.action.PerformInteractiveRebinding()
            .OnMatchWaitForAnother(0.1f)
            .OnComplete(x => RebindComplete(pair))
            .Start();
    }

    void RebindComplete(TextIARPair pair)
    {
        _rebindingOperation.Dispose();

        _controls.Enable();

        Save();
    }

    public void ClearBindings(InputActionReference iar)
    {
        iar.action.RemoveAllBindingOverrides();

        Save();
    }```
When I change a keybind it assigns it correctly but when I leave the pause menu I cannot perform any inputs, also if I restart play mode it doesn't seem to save any of the keybinds. A lot of this stuff is going over my head tbh

[swift falcon]

When I do this I get an empty string back:

string rebinds = _controls.SaveBindingOverridesAsJson();
        Debug.Log(rebinds);```
But this returns the new overriden keybind at the same time:
```cs
string KeybindToText(InputActionReference iar)
    {
        int bindingIndex = iar.action.GetBindingIndexForControl(iar.action.controls[0]);

        string path = iar.action.bindings[bindingIndex].effectivePath;

        return InputControlPath.ToHumanReadableString(path, InputControlPath.HumanReadableStringOptions.UseShortNames);
    }```

So I think there's something wrong with SaveBindingOverridesAsJson() but I'm struggling to think of why

Although considering the fact that the overriden inputs aren't getting detected, the problem is probably there
What's wrong with this code?

// Variables
InputActionRebindingExtensions.RebindingOperation _rebindingOperation;
InputActionReference iar;

// During Binding
_rebindingOperation = iar.action.PerformInteractiveRebinding()
            .OnMatchWaitForAnother(0.1f)
            .OnComplete(x => RebindComplete())
            .Start();

// On Complete
    void RebindComplete()
    {
        _rebindingOperation.Dispose();
    }```
The problem must be within here

[swift falcon]

Ok I found out why the player was unable to move, unrelated problem. But the keybinds still aren't saving

Nor being applied at all

[swift falcon]

Problem is still within here

[swift falcon]

Ayy got it working, problem was with the fact that the InputAction I assigned in the inspector was different to the one I actually used for detecting input and saving/loading. I didn't realise they were different :P whoops

[soft shard]

Why would you need to mark either as "is trigger"? Are you using OnTriggerEnter on a specific object?

[rough sorrel]

One question, is there a way to like lock the cursor to the middle of the screen/hide it but still be able to interact with world canvas elements such as buttons please?

[leaden ice]

Locking the cursor doesn't prevent this

[rough sorrel]

when I lock the cursor I can't use the UI

[rough sorrel]

Like, at first with the mouse unlocked I can click and move the scroll rect, but once I lock it I cannot click or move it anymore

[ionic socket]

I'm having an issue with the Async/Await workflow. Let's say I have methods A(), B(), and C(). Method C() is a async Task that awaits some other Task. within Method A(), there's a loop which calls B() each iteration, and within B(), a loop which calls C() in each iteration. The execution of Method C() stops when it reaches the await statement; however, methods B() and A() each complete their loop statements without waiting for the Task in method C() to be fulfilled.

If I want the await in Method C() to halt the entire chain, does that mean that A() and B() also need to be async methods that are awaited?

For cleanliness purposes, I dislike making every method in the chain an async method because it mostly doesn't ever need to await anything and I find myself adding a lot of "return Task.CompletedTask;" at the end of methods. Is there another way to go about this other than marking every thread that might be awaited downstream without converting them all to async Tasks?

[steel elk]

Async programming tends to "infect" the project like this, at some point you either start blocking or possibly do some black magic with a custom scheduler that blocks in a controlled manner to prevent locking a program up (speaking broadly and coming from Rust, not even sure if that second part can be done in C#)

[heady iris]

it's turtles all the way down

[ashen yoke]

yes

there is no way to "halt" a normal method

[heady iris]

https://learn.microsoft.com/en-us/archive/msdn-magazine/2013/march/async-await-best-practices-in-asynchronous-programming

[ashen yoke]

async method is converted to a state machine

its literally a giant switch under the hood

[heady iris]

same for enumerators, right?

[ashen yoke]

yes

[heady iris]

every vaguely magical C# feature is just a state machine in a trenchcoat

[crimson atlas]

assumed you needed a trigger
did some reading and in the end i don't
however i was left confused as to what occasions require a trigger and what do not use on

[heady iris]

you need a trigger when you need a trigger!

[crimson atlas]

i read the manual on it, but still
pacman and ghosts do not interact with each other in what physics are concerned (there is no physics simulation)
it's basically, collision = one of them goes poof
wouldn't marking as trigger make the collision cheaper or something because no physics simulation?

[heady iris]

when you want to detect things without collisions

[heady iris]

yes, triggers are simpler.

the main draw is that you don't mess with physics.

[crimson atlas]

but isn't a trigger necessarily a collider (with "is trigger" marked)?

[heady iris]

you don't run into an autosave point and bounce off

you just walk into the trigger zone

[crimson atlas]

but can't you make do with a collider (without a rigidbody)?

same thing, "OnCollisionEnter" -> save game

[heady iris]

sure

but then the player can't walk into the zone

it's a collider

[crimson atlas]

OH

so it's going to block stuff?
and "is trigger" makes it allow stuff through?

[heady iris]

yes

[crimson atlas]

didn't realize a collider was going to block stuff unless it had a rigidbody

so no rigidbody necessary to block stuff then?
no idea why i always assumed you needed a rigidbody to block

[heady iris]

colliders are colliders

having a rigidbody is necessary to be affected by physics and to receive collision events

One of the two objects must have a rigidbody to receive any physics messages

[crimson atlas]

wait, on "to receive collision events"

can you give me an example of a collider interaction that requires a rigidbody?

[heady iris]

well, to start

if you have two objects with colliders, and neither has a rigidbody

collisions don't really matter

they ain't moving

if you manually move them into each other, you won't get collision events

OnCollisionEnter, for example

[crimson atlas]

hmmm now it starts to make sense

[heady iris]

One of the two must have a rigidbody for these messages to be sent

https://unity.huh.how/programming/physics-messages/3-collision-matrix-3d
https://unity.huh.how/programming/physics-messages/3-trigger-matrix-3d

[steel elk]

Rigid body = something to be controlled by physics, things without it but with colliders are essentially static objects that can be run into

[crimson atlas]

but pacman and the ghosts don't need rigidbodies to be implemented do they?

i mean i'm not going to use any physics simulation to move them around

[heady iris]

They can use a kinematic rigidbody

[crimson atlas]

how can i implement the object "touch" or "overlap" detection?

[heady iris]

Kinematic rigidbodies are still understood by the physics system

But they aren't affected by physics

[lean sail]

you can detect if they overlap by other means, but might as well still use collision events

[crimson atlas]

so i can't actually code "touch" events without rigidbodies in the end?

i mean with the given tools, not having to resort to coding my own

talking about colliders, rigidbodies, triggers etc etc

and the "oncollision" "ontrigger" events

[heady iris]

Rigidbodies are required.

[lean sail]

Yes u need a rigidbody, otherwise your object isnt really supposed to move and collide

[latent latch]

it's funky but something needs a rigidbody, but like that rigidbody can be kinematic

[heady iris]

It's fine if you aren't making the player be affected by physics

like, the player doesn't get pushed around

[crimson atlas]

now i'm confused as to why make colliders and rigidbodies separate thigns

[heady iris]

although, a kinematic rigidbody also ignores collisions

[heady iris]

a collider is the shape

a rigidbody is what makes you into an object that gets pushed around by physics

[crimson atlas]

so the collider is basically the shape of the rigidbody?

[lean sail]

because a collider and a rigidbody are 2 entirely separate things

[heady iris]

it's the shape of the object

[lean sail]

a rigidbody has no shape

[echo plaza]

Hey there, I'm wondering how I could go about adding a planting mechanic for my game. More specifically, I have a few things I want to try and do.

First, I want to create a box collider that would go around the entire plant model, which is made up of multiple gameobjects. Next, I'd want to apply a material to both the parent model and all of its children.

[steel elk]

It's worth considering that if you're using a physics engine for a Pac-Man clone you might be bringing an automatic shotgun to a knife fight

[crimson atlas]

if i have a collider (no rigidbody) setup, and another collider (with rigidbody) touches it, will it stop moving (and be blocked) by the no-rigidbody collider?

[ashen yoke]

best to think of a collider as just a collider

its just a physics shape

you can have 10 colliders representing a single "object"

object in this case is some abstraction, like a mesh

[crimson atlas]

let me see if i'm starting to understand it better

[heady iris]

yes. because the rigidbody respects colliders.

[lean sail]

yes, you can test this by putting a rigidbody on a cube. Then just put another stretched cube to act as a floor. 2nd cube with no rigidbody

[ashen yoke]

rigidbody treats a group of colliders as a physical object

you can have many colliders under the same rigidbody and they will act as a single physics object

[lean sail]

the only slightly annoying part about many colliders is dealing with which one got hit

[ashen yoke]

that is solved through relaying events to the root

[lean sail]

if that matters for your game

[crimson atlas]

so an object with a collider and no rigidbody would be better suited to serve as a boundary or a no-physics wall of some kind?
whereas if i mark it as "is trigger" i transform that same objecti with collider but no rigidbody in a penetrable/traversable "area" (instead of a wall) that will send "ontrigger" events?

[ashen yoke]

colliders still participate in physics they just dont move

[lean sail]

yea its easily solved, i just dont like having a script on each child object. Maybe its different for me, i got 18 colliders :p

[ashen yoke]

a floor collider doesnt need a rigidbody, it doesnt move

but physx still uses it to compute collisions for rigidbodies

[crimson atlas]

so object+collider (no rb) = "wall"
object+collider (no rb) +isTrigger = "named traversable area"
object+collider+rigidbody = an actual movable object in the physical world

[latent latch]

If you want to ignore rigidbodies completely, just cast (sphere/box) yourself. You wouldn't use OnTriggerEvents but rather your own methods.

[crimson atlas]

i'd like to use the stock functions as much as possible, especially to actually learn them

[latent latch]

You'd have more control on when to check as well which is a plus

[crimson atlas]

i've published a game (shocking right) using all of that but without understanding 20% of it

what if i have an object+rigidbody with a collider set as "isTrigger"
how would such a monster behave?

[lean sail]

kinda, the wording is slightly off. you can still move objects that dont have rigidbodies, but thats just moving the actual transform.position. Rigidbodies allow them to move via forces, have angular rotations, be affected by gravity

Like you can close and open a door without putting a rigidbody on it

[crimson atlas]

ohhhh, the translate vs. force was very insightful

[lean sail]

as for the triggers, u can use them however u want really but yea its more so detecting if something entered an area, or just left the area

[crimson atlas]

but how would a rigidbody with a collider marked as trigger work?

[lean sail]

a trigger is different, your rigidbody would essentially just fall through the floor

[latent latch]

Rigidbodies are mostly for using unity's physics, not primarily a focus (more of a subset) on the collisional aspects, but there is some functionality that it introduces that does help against faster projectiles

[crimson atlas]

do rigidbodies not need colliders in order to collide (to stop, be stopped or physically interact) with other stuff?

[lean sail]

if you give your rigidbody a collider AND trigger, you can use the trigger to detect if things are within your trigger area for example. Like if you had items to pickup from the floor, you dont want to calculate the distance between yourself and every item. You would rather have a trigger that can detect if an item entered its bounds

triggers just have a different use

[crimson atlas]

that means two colliders right? one of them being marked as trigger?

[lean sail]

yea

[crimson atlas]

so marking a collider as a trigger transforms it into something else entirely i guess?

i mean, it stops being a "collider" since it won't collide with anything anymore?

it's just detect overlaps (ontriggerenter)?

[lean sail]

I guess you can word it like that yea. One of the 2 objects still needs a rigidbody though

also 2 triggers cannot collide

[lean sail]

actually i remember this being something weird, someone corrected me on it but i forgot what they said
https://docs.unity3d.com/ScriptReference/Collider.OnTriggerEnter.html

If both GameObjects have Collider.isTrigger enabled, no collision happens
the docs say this but i think that refers to an actual Collision instead of OnTriggerXXX

[heady iris]

This is wrong. The "colliders overview" page contradicts that

https://docs.unity3d.com/Manual/CollidersOverview.html

I think it was true at one point...

i remember reading about people complaining about it

[lean sail]

ah i once again fell for the misleading wording

[heady iris]

i'm pretty sure the page is asserting that no messages get sent

The same applies when both GameObjects do not have a Rigidbody component.

this is true: no trigger messages get sent

[lean sail]

english is hard

[crimson atlas]

wait

so it's actually impossible to implement "pacman eats ghosts" without rigidbody, be it with OnCollisionEnter or OnTriggerEnter
since any will require at least one rigidbody?

[heady iris]

Yes. If you want collision events, you must have a rigidbody on at least one object

end of story.

Having a rigidbody does not mean that the object is affected by physics

it can be kinematic

kinematic rigidbodies are not affected by forces

you just have to move them with Rigidbody.MovePosition instead of setting the transform's position directly

that's all

[crimson atlas]

hm gotta check my old game source

pretty sure i just use translate

[heady iris]

that might work, sometimes

the problem is that this moves the object without letting the physics system handle it

it might be ok

[crimson atlas]

but yeah a rigidbody and colliders (and triggers) to implement a "one object goes poof" on "touch"

it's the game snake basically, but with smooth movement

i move the snake with translate and rotate purely, no force stuff, it's a top down 2d game

when snake "mouth" collider enters the "fruit" trigger collider, fruit gets eaten

snake grows

i remember i (had to) put a rigidbody in the mouth object

had to or it wouldn't trigger iirc

that's so weird to me thogh. not sure if i'm making sense.

i mean, there are no physics anywhere.
why do i have to place a rigidbody in order for the game to detect the "touching" or "overlapping" of two areas (colliders in this case)

[crimson atlas]

hmm. seems i'm probably looking for a "kinematic"-rb-snake and a "static"-rb-fruit
it's probably how unity would want me to do this

[heady iris]

yes

[crimson atlas]

however i'm not sure i wanna use MovePosition and MoveRotate.

i don't want forces, i'm specifying how many pixels i want it to move, and i'm controlling velocity by script

[heady iris]

Those are not forces.

MovePosition sets the position

[crimson atlas]

oh then that's awesome

[heady iris]

https://docs.unity3d.com/2022.3/Documentation/ScriptReference/Rigidbody.MovePosition.html

[crimson atlas]

so it teleports, but collides along the way lol?

[heady iris]

if you're using continuous collision detection, yes

[crimson atlas]

omg i'm going to have to rewrite my whole snake body movement script
it was just a list of transforms.
i guess it's about to get a lot more complicated

collider and otherCollider is SO unintuitive
collider refers to the OTHER
and otherCollider refers to myself?
is it really like that or i'm missing something?

snake script's OnCollisionEnter's collision.collider returns info about the fruit's collider?
and collision.otherCollider returns info about the snake's own collider?

[tall violet]

fr

[crimson atlas]

lol something's definitely wrong

[simple egret]

.collider is the other collider (the object you collided with)
Then once you get a contact point, there's .thisCollider (yourself) and .otherCollider which is like the Collision's collider property above

[crimson atlas]

but collider and otherCollider are giving me different results, they're behaving invertedly

[jaunty needle]

I'm facing another similiar issue for some reason

[crimson atlas]

hmm i wonder if that might be happening because i'm using transform.translate to move them (and not MovePosition)

[simple egret]

Probably

[jaunty needle]

A nullreferenceexception

[simple egret]

A collision can have multiple contact points

[jaunty needle]

    {
        stairSpawner.ReachedEnd += EndGame;
    }

oop

sorry my bad

same solution

[crimson atlas]

doesn't give me the "thisCollider" option

[simple egret]

Ah I was looking at the 3D Collision class, which is different hang on

[crimson atlas]

head = sickles
the yellowish ball above and behind it = resource

[simple egret]

Yeah seems like otherCollider is yourself, docs are not easy to read on that

[crimson atlas]

the names used are not intuitive

[simple egret]

"the incoming collider" - well both colliders are "incoming", it's relative

[crimson atlas]

besides it's inconsistent with how the 3d version works i guess

[simple egret]

As for the thisCollider and otherCollider, you need to get a contact point for that using GetContact(), they're not on the Collision2D itself

Great, for 2D they're not named the same as for 3D!

ContactPoint2D's thisCollider is just collider

[lusty dune]

Why don't you use collision.tag == tagname ?

[crimson atlas]

but is that "collider" really referring to the script object's collider? and not to the collider of the other guy it hit?

[simple egret]

Actually, no, it's the collider of the other object

[crimson atlas]

exactly

that's where the confusion resides and it's really unintuitive

[simple egret]

otherCollider is yourself, wtf were they on when they decided on the naming

[crimson atlas]

see what i'm saying

tried to google "unity collider otherCollider inverted" but no luck
i refuse to believe nobody ever saw that
i'll take some time to write something on discussions and see what people say

[unreal island]

I'm trying to move my project from editing in windows to linux. I have Unity 2022.2. When I opened the unity editor to the project in ubuntu I got a huge number of errors all saying that GraphicsFormat.R8_UInt (I'm trying to set a RenderTexture.stencilFormat) is unsupported. However when I look online I see this suggested as the most commonly supported format (https://docs.unity3d.com/2022.2/Documentation/ScriptReference/RenderTexture-stencilFormat.html).

How can I figure out what formats I can support / is there anything I can do to make this format supported?

[unreal island]

Thanks sorry

[crimson atlas]

i think i've solved the mistery on "collider" and "otherCollider" naming choices

at some point in the past there was no "otherCollider" (it isn't hard to referece one's own collider to get info)
it was just "collider" and refered to the "other guy"

then they implemented "otherCollider" but left "collider" referring to the other guy (and otherCollider to oneself) so people wouldn't need to rewrite code or something

only reasonable explanation

[woeful spire]

I'm rotating object's localRotation in code. The snippet looks like this.
transform.localRotation = Quaternion.Euler(stopAngleAdd, transform.localRotation.eulerAngles.y, transform.localRotation.eulerAngles.z);
the stopAngleAdd just has the value 8.
When doing this the objects stop either at 8, 0, 0 in rotation (which is what I want)...
Yet other ones stop at 172, 0, 0...
I noticed this is 180 - 8, which is the same value as stopAngleAdd, so I guess I'm missing something with Quaternion.Euler?

the objects could have any degree on the x-axis when the snippet is run, so we never know from what rotation this is done.

[golden vessel]

Hey, can I reinitialize an array? Will it keep the previous elements if I make it bigger? Or should I just use another array?

[woeful spire]

If you want to make it bigger, I'd suggest using a List instead.

this way the length is variable.

[golden vessel]

Hmm let me think maybe I'm going about this wrong to begin with.

[quartz folio]

EulerAngles are derived from the internal quaternion. Euler angles can represent the same rotation in a number of ways, and you have to account for that

[woeful spire]

Okay...
"the same rotation in multiple ways" meaning (0, 0, 0) = (360, 0, 0)?
I'm not sure exactly what this entails I think...

[quartz folio]

More like: 90, 0, 0 might be the same as 0, -90, 90 (please don't test this, it's just an example)

Which is why constructing a rotation from incomplete individual portions of a euler angle that was derived from the internal quaternion is a bad idea

if you're doing this sort of thing it's generally better to keep track of your own individual rotation values and apply them to the transform

instead of reading back from the transform and hoping the representation in eulerAngles is what you expect

[golden vessel]

Why are EulerAngles used for to begin with? Idk much about it but I'm pretty sure you need only two variables to completely define an angle right?

[quartz folio]

What do you mean? They are the rotations around X Y and Z

[woeful spire]

So... in my case it would be a better idea to calculate the rotation needed to end up where I want and apply it?

[quartz folio]

They are only used for authoring and utility purposes, and in some specialised places like animation

[golden vessel]

Well you need only 3 variables to define any point in space from what I remember

But distance shouldn't really matter

If you're interested in angles only

You can go (x,y,z) or (r, phi, theta)

[quartz folio]

I'm not sure what your complete setup looks like, but I recommend keeping track of two floats for your yaw and roll, and use Quaternion.Euler(stopAngleAdd, yaw, rol); instead of grabbing from the transform. But I have no idea if your setup allows for this

[quartz folio]

That's what Euler Angles are though, X Y Z rotations. Are you asking why we use Quaternions?

It's because they don't suffer from gimbal lock

They also interpolate directly instead of having weird axis problems

[golden vessel]

ok thanks for the explanantion, I'm going to google those words 😄

[woeful spire]

Okay, I see. I'm only interested in changing the x-axis's rotation of the object, but I still need to keep track of the other axes to make sure they don't "interfere" with my x-axis-number as it might be interpreted differently if the Z and Y values are strange.
Does that make half-sense the way I wrote it?
I think this makes sense as it goes back to "90, 0, 0 might be the same as 0, -90, 90"-kinda deal. Yes?

[quartz folio]

Yes, that is likely your issue

Another option is to use a compound transform that only applies a rotation in that one axis so you don't have interference from the other rotations

[woeful spire]

This sounds great for this specific use case. I googled compound transform and found nothing though. Is it saving a specific vector and using it to apply rotation? How would that look?

[quartz folio]

Just having another transform under this one

Two transforms in the hierarchy instead of one

[woeful spire]

ahh I see. That way I'd always know the values of the other ones. Hah, that's an interesting use - never would have thought of that.
I'll try the first method and do the other if I can't figure it out. Thanks a lot :)

[neat echo]

is there a simple solution to outlining the voxel that a player is looking at if all the voxels make up a single mesh?

if each voxel was its own mesh then that'd be a lot simpler but they're all a part of one big mesh

i just wanna know if theres a simple way to deal with this or if its gonna be way outside the scope of this project

i should clarify: i want to highlight just the face that the player is looking at

[tiny mantle]

why isn't this spawning the grass where i need it to, the grass tile needs to spawn anywhere between the last tile and 3 tiles in front of it https://gdl.space/elubicayet.cs

[crude mortar]

make a sprite that is just the border highlight you want, raycast from the player to hit the mesh, then use the normal / point of the raycast hit to place the sprite in the right position and with the right rotation

you can get the correct position by rounding then adding an offset, and then just set the forward of the sprite to be the hit.normal

by sprite I just mean something like this

[gray mural]

How do I "name" methods like Awake, Start, OnGUI, Update, LateUpdate etc.?

[real sequoia]

I have a score manager script that increases the score based on height difference. It's working as expected, but instead of increasing the score in the Update function, I want to create an event. I know how to create an event, but I need suggestions on how to trigger that event. For example, in a coin-based score system, touching the coin triggers the event and increases the score. I want to implement a similar concept in my game. Any suggestions or examples would be appreciated.

using UnityEngine;

public class ScoreManager : MonoBehaviour
{

    #region Variables

    [SerializeField] private Transform player;

    // Example - If the scoreIncrementHeight is 2, it means that if the player moves up by 2 meters or 2 grid units, their currentScore will increase by 1.
    [SerializeField] private float scoreIncrementHeight = 2f;

    private float lastRecordedPlayerHeight;

    private float currentPlayerHeight;

    private int currentScore = 0;

    private int highScore;

    private const string HIGHSCORE_PLAYER_PREFS_KEY = "high_score";

    #endregion

    private void Start() {

        currentPlayerHeight = lastRecordedPlayerHeight = player.position.y;

        highScore = PlayerPrefs.GetInt(HIGHSCORE_PLAYER_PREFS_KEY);

    }

    private void Update() {
        IncreaseScoreLogic();
    }

    void IncreaseScoreLogic() {

        currentPlayerHeight = player.position.y;

        float heightDifference = currentPlayerHeight - lastRecordedPlayerHeight;

        if (heightDifference >= scoreIncrementHeight) {

            lastRecordedPlayerHeight = currentPlayerHeight;

            currentScore++;

            // High Score
            if (currentScore > highScore)
                SetNewHighScore();

        }

    } // IncreaseScoreLogic

    void SetNewHighScore() {
        highScore = currentScore;
        PlayerPrefs.SetInt(HIGHSCORE_PLAYER_PREFS_KEY, highScore);
    }

} // Class
```cs

[gray mural]

using UnityEngine;

public class CoinCollector : MonoBehaviour
{
    public static event Action<int> OnCoinCollected;

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            OnCoinCollected?.Invoke(1);

            Destroy(gameObject);
        }
    }
}

// e.g. your ScoreManager class

private int _currentScore;

private void OnEnable() => CoinCollector.OnCoinCollected += CollectCoin; // + on enabke

private void OnDisable() => CoinCollector.OnCoinCollected -= CollectCoin; // - on disable

private void CollectCoin(int value) => _currentScore += value; // do when collecting coin

[real sequoia]

Thank you for the quick response. What you share is also i found on google but in my game score gets increased based on height difference in that case how to trigger an event

private void Update()
{
    currentPlayerHeight = player.position.y;

    float heightDifference = currentPlayerHeight - lastRecordedPlayerHeight;

    if (heightDifference >= scoreIncrementHeight)
    {
        // Trigger the event here
    }
}

But in this case, using event is no good because what i am doing before is same as this

[gray mural]

I don't get it

[real sequoia]

I don't want to put my increase score logic in Update, that's why I am using event to make my score manager optimize.

[real sequoia]

Sorry English is not my first language, that's why its hard for me to make a clear point.

[gray mural]

my English is poor too, continue, please

[gray mural]

yes, I have shown you how to do this without using Update

oh, I see

[gray mural]

but I still think you need to trigger it in Update

do you still need to trigger in in OnTriggerEnter?

or just within Update?

[fervent furnace]

unfortunately you have to do it in update to continue check whether the new input data is > than old record

[real sequoia]

No, in my game score increases based on height difference, I don't have any coin using which I can trigger event inside OnTriggerEnter

[gray mural]

ok, so you should do it in Update, LateUpdate, FixedUpdate

[real sequoia]

Ok got it

[gray mural]

there is no other option, as far as I know

[real sequoia]

So last question, inside which function I should call my increase score logic, which is more optimize

[real sequoia]

This point is clear now.

[gray mural]

I wound call it in Update

[lean sail]

what if you have a trigger placed so the bottom is at your previous highest point, then anytime you are within the trigger, send the trigger higher

[real sequoia]

I also heard inside FixedUpdate only put physics related logic

[gray mural]

I guess, yes

[fervent furnace]

now the physics engine have to keep track the one more collider and fire the event if you touch it

[lean sail]

Therefore it's the physics engines problem, not mine

[lean sail]

U can put other logic inside, but if you're looking at highest point you'll likely want to do that frame by frame (update)

[real sequoia]

Got it.

[fervent furnace]

you just throw the workload from your logic to physics engine in Fixed update....

[real sequoia]

So its not a good way to put other than physics related logic in Fixed Update right?

[fervent furnace]

i just reply to the idea of using collider
the problem is wherever you put it you "optimize" it by changing it sampling interval

[real sequoia]

Got it. But I am little bit confused with Fixed Update function, can I put other logics which are not related to physics inside Fixed Update?

[fervent furnace]

you can

[real sequoia]

Is this a good way? Everyone does it?

[fervent furnace]

if your logic need to sample in constant time interval then you may want to put it in fixed update
but apart from physics i cant come up with other example

[real sequoia]

Thank you everyone for your quick responses.

[lean sail]

well sometimes u cant really separate out some logic. Like if you need to compare values (the height), check if something happened, then apply some physics function, u cant just take those comparisions and place them in update. Most of what I have in fixed update isnt pure physics functions

but most of it is eventually used for physics

[real sequoia]

Got it.

[valid trench]

hi im trying to make a platform fighter (similar to smash bros) and i was making the knockback functionality.
according to the wiki, this is the knockback formula used in the game. what is this function exactly returning? how can i apply knocback based on whatever this function returns? do i just multiply the value to my velocity? i did try that but it didnt really work. also how can i get the angle for the knockback and stuff too?

[lean sail]

can u send the link on this page? it should define what these variables are

[valid trench]

i have an understanding of what the variables are

i just dont know what value im getting

like

what im supposed to be doing with it

https://www.ssbwiki.com/Knockback

thats the link

[lean sail]

the value returned is just a number, so they likely have an angle they apply this force at

[valid trench]

i tried getting an angle but its not working

my idea of the angle wwas

[lean sail]

the angle used seems almost arbitrary, it says it depends on the players gravity but thats likely just due to the formula

[valid trench]

transform.position of the player getting attacked - whatever the centre of the attack collider is returns the direction

[lean sail]

u probably have to make it up per move tbh

[valid trench]

and then for angle i saw some thread doing something like this

[lean sail]

I assume that wont really work for a lot of interactions, imagine a tall and short character fight. one would only launch the other down towards the floor

[valid trench]

the angle?

[valid trench]

oh yeah that makes sense

how else can i do this then?

get the angle i mean

like the angle where the player is supposed to be launched towards

[valid trench]

and im assuming the returned value of this function is the force that is to be applied

[lean sail]

I dont know much of how the game works, I really would just make up an angle depending on the move. At least this way, moves will consistently launch in a certain direction

[lean sail]

yes i think so too

[valid trench]

but how would the "making up" work

what im tyring to get is

wait let me draw this somewhere

ok this is confusing but the idea is

[lean sail]

as in you predetermine some range of angles, this is just like game design, not a coding calculation. The calculation is just going from the left or right vector, to the rotated one

[valid trench]

blue is the player getting hit, red is the attacking collider, and green is the direction the player gets thrown toward

[lean sail]

the green would be like 45 degrees then, thats really all. You just associate some angle to moves

[valid trench]

i see

wait i watched this video ill timestamp it

one sec

https://youtu.be/CxvdO_kkXmY?t=41

[lean sail]

this seems more like something u need to watch more than me :p

[valid trench]

i dont really understand how they get that exact angle

like where they derive it from

[lean sail]

some parts of the wiki you linked still leads me to believe these angles are predetermined, but either adjusted or the force is adjusted based on factors

[valid trench]

yeah i did watch it but didnt find anything about the angles

[vernal plank]

why
var folders = AssetDatabase.GetSubFolders("Assets/Silex-Materials_Pack/Textures");
with Debug.Log(folders); returns nothing System.String[]
while trying to print one element of the array returns it ?

can you print the whole array without looping

[lean sail]

one part in the wiki states

In Ultimate, moves that launch at angles between 70° and 110° now instead cause characters'....
which further makes me think that the angles are predetermined, but adjusted

[valid trench]

thats like

the sakurai angle or something

so like

[lean sail]

you can with string.join, but you should just loop through. Also debug the length to see if its truly nothing

[valid trench]

idrk much about it but the general idea i got is that they first derive the angle, and then perform some sakurai angle thing based on that initial angle and the knockback from the attack

[lean sail]

Just saying i have no clue what sakurai angle means

and i dont really intend to learn

[valid trench]

yeah i dont either lmao

know what it means

alright ill try taking a look at the wiki again and let you know if i get somewhere

[lean sail]

really for your game, just getting something working is better and then try to adjust it

you dont need to make a smash clone. And not many people are gonna notice your angles dont 100% line up to their calculations

Predetermined angle + adjustment due to weight, place hit at, force, and health are perfectly fine

[buoyant crane]

very likely the angles are hard-coded per hit box (exception is the sakurai angle which has some conditions) https://www.ssbwiki.com/Hitbox

[valid trench]

i see

[valid trench]

that makes sense

[earnest gazelle]

Hey, one question, typically in voxel based games, how are voxels selected for example for digging?
It is an isometric game but the camera can rotate
Screen space (2d rect) or world space? A player presses the mouse button and drag it, then drop.
I would say screen space. What do you think?
In 3d model softwares like Maya, it is screen space by default.

Hey so i have a little Problem, if i write something with Input.touches it doesnt do it. Anything that has this in it for ex. Debug.log it doesnt do it and i didnt find anything about it

[gaunt blade]

hey, so something really confusing is happening

        {

            float prevAngle = 0;
            for (float i = 360/steps; i <= 360; i=i+360/steps)
            {
                Vector2 vertex1 = new Vector2(this.radius * Mathf.Sin(prevAngle), this.radius * Mathf.Cos(prevAngle));
            }
        }```

For some reason, it's not recognizing the multiplication operator within the Vector2 object instantiation.

And so it's throwing an error instead of doing multiplication

Anyone know why this might be the case?

The code for the entire class is this:

    {
        private Vector2 center;
        private float radius;

        public Vector2 getCenter() { return center; }

        public float getRadius() { return radius; }

        public void render(float lineWidth, float steps)
        {

            float prevAngle = 0;
            for (float i = 360/steps; i <= 360; i=i+360/steps)
            {
                Vector2 vertex1 = new Vector2(this.radius * Mathf.Sin(prevAngle), this.radius * Mathf.Cos(prevAngle));
            }
        }
        public Circle(Vector2 center, float radius)
        {
            this.radius = radius;
            this.center = center;
        }

    }```

I really don't see a reason that it'd struggle to identify the multiplication operator.

Actually nvm, I just restarted visual studio and it fixed itself. Weird bug with the IDE ig?

[royal pulsar]

how do i decide between a behaviour tree and a state machine? is it simply an issue of complexity? I have a simple AI that at this point will only roam and chase the player upon line of sight.

[cold parrot]

FSM if you deal primarily with events that happen on state transitions, BT if you are primarily concerned with sequencing a non-trivial action plan over time. Ideally you combine both: FSM handling triggers and implementing state’s internal behavior with shallow BTs.

I have a ScriptableObject that contains some properties that are used in game. When I change the values in the inspector, it seems all fine. When I deselect and select it again, all values are back to what they were before I changed anything. And they are not reset to their default values, just some values I used a while ago. Currently it's impossible to change the property values now. It just always resets back. Any idea what could cause this?

that's what I was talking about

[gray mural]

what?

[knotty sun]

what did you think it was based on?

[vernal plank]

yeah and it doesn't have c: too

[gray mural]

macOS is not linux

[knotty sun]

MacOs is linux with a custom GUI

[vernal plank]

even tho mac is not linux both they are unix based

so they are pretty much have the same terminal and same structure but macOS is locked

[gray mural]

it's not so

[vernal plank]

or in a better world mac is more restrictive

[gray mural]

restrictive?

[vernal plank]

Well Linux is Unix-like
And Mac is Unix based

this is so confusing lmao

[gray mural]

is it comfortable to use linux?

[vernal plank]

once you get used to it yeah
when you starting out its pure pain

[gray mural]

everything is actually for Windows.

every video, tutorial or docs

[vernal plank]

once you get used to it you would never go back to windows

unity seems fine on linux

never had an issue

i also use unreal godot

zbrush

substance designer

[gray mural]

Scratch too?

[vernal plank]

what ?

[gray mural]

sounds like you should consider using something one

[gray mural]

Scratch is also GameEngine

[vernal plank]

ill look it out
btw you can try linux on a live USB env

[gray mural]

the hardest one
https://scratch.mit.edu/projects/editor/?tutorial=getStarted

[vernal plank]

before you even install it

[gray mural]

that's something I won't probably understand 🫠

[vernal plank]

you dont have to install it as your daily driver to try it you can get a USB stick and boot your system from it

[gray mural]

oh, I see

[vernal plank]

if you ever wanna try it hit me up you can add me too

id love to help back

[gray mural]

I am ok with windows 😁 thanks though

[urban marsh]

Hello everyone !
I am trying to code a script that would put a UI element A at the same position and size as another element B which is elsewhere in the hierarchy.
I tried changing the transform.position, including before/after changing parents, but I can not manage to get a good result.
Anybody knows how to handle that ?

[dark knoll]

Each time I deselect my ScriptableObject asset it reverts all changes to properties back to what they were before. I never had this issue before, what could it be?

In fact I can only change the values by editing the .asset file in a separate texteditor now...

[leaden ice]

Show the code for it

And explain which things you are trying to change

[night sparrow]

i have a question in unity's editor.
say i have abstractclass base, and said class have 3 classes that implement it: class1, class2, class3.

i have another script which has public base variable
is it possible in the editor to assign class to variable

[dark knoll]

Short version of it (it has quite a lot of properties):

[CreateAssetMenu(fileName = "settings", menuName = "Settings")]
public class Settings : ScriptableObject
{
[Tooltip("What temperature will be tundra.")]
[Range(0f, 1f)]public float TundraThreshold = 0.3f;
}

If I change this value in the inspector, for example to 0.2, when I deselect the asset, it will just revert it back to what it was before, no matter what.

I must say I'm pleased I can at least change it by just editing the asset in a txt editor, I was going nuts before I realized that simple solution

[night sparrow]

more in depth:

public class DataClasses
{
  public abstract class Base {}
  public class FirstClass : Base {}
  public class SecondClass : Base {}
}

and in another script:

public class Whatever: MonoBehaviour
{
  public DataClasses.Base variable;
}

i want in the editor to choose if variable is FirstClass or SecondClass

[simple egret]

Without making a custom inspector for your Whatever class, you can't. Unity doesn't support polymorphic serialization

[craggy veldt]

you can use SerializeReference for this

[mossy snow]

another option is to make your base class a ScriptableObject, and all your subclasses will have to be assets

[night sparrow]

can you give an example on how i can do this?

[craggy veldt]

https://docs.unity3d.com/ScriptReference/SerializeReference.html

[craggy veldt]

pls don't 🥹

[mossy snow]

Why not? It's data, and he won't have to create an inspector or do anything hacky to choose his variable

[night sparrow]

i can't seem to get this to work in the editor at least, as i understood it, it just helps unity serialize objects correctly instead of just saving base

[mossy snow]

SerializeReference has never worked well for me, if it's simple you can use my suggestion, otherwise you might as well use something like odin

[craggy veldt]

read the docs very carefully, see the Dos and Donts.. and the docs is very throughly explaining on how to use it

[craggy veldt]

it's one of the most beautiful thing ever happened to Unity 🥹 ... and for once the docs is very good at explaining how to use it properly

[mossy snow]

I strongly suggest you try and use it first. Their example is janky for a reason

[craggy veldt]

been abusing it for awhile now 😄

it's splendid

[night sparrow]

That's what i did:

public class DataClasses
{
  [Serializable]
  public abstract class Base {}
[Serializable]
  public class FirstClass : Base {}
  [Serializable]
  public class SecondClass : Base {}
}

public class Whatever: MonoBehaviour
{
  [SerializeReference]
  public DataClasses.Base variable;
}

[craggy veldt]

bruh

[night sparrow]

?

[craggy veldt]

are you sure you read the docs properly?

[serialiazereference] Base baseClass = new FirstClass()

[hushed needle]

Hi, I'm currently watching a video to implement the A* algorithm in unity, my game is a top-down 2d map (like enter the gungeon) but his game is a top-down 3d map . he Wrote a code to adjust the weight of each grid(like, in snow you are much slower than flat surface) which doesn't work for me because I can't do the same in 2D. Any idea how to do the same in 2d? his code:

[fervent furnace]

i use physics2d.overlapcircle

[heady iris]

Are you using an actual Grid component?

If so, you can convert a world-space position to a grid-space position.

(and then find the tile for that grid-space position, if one exists)

or is this not tilemap-based?

[hushed needle]

for grid, i built a grid class myself. and yes tile map based

[heady iris]

can you take a world-space position and turn it into a grid-space position?

[hushed needle]

i have a method for this

[heady iris]

then you just need to figure out which grid space you're on and then get the tile at that space

no need for physics at all

[hushed needle]

how can i do this without physics?

[heady iris]

by doing this.

your question is "how do I find the tile at a certain position?"

you don't need to do any raycasting for this. you already have a regular grid of tiles.

[hushed needle]

Oh sorry I misunderstood, I can't do that.

[heady iris]

Then I'd suggest implementing that.

It's very important to be able to convert back-and-forth between world and grid space.

[hushed needle]

I have two separate grids, one for a* and one for painting. I need to create a method to check my drawing grid at a* grid position, right?

[heady iris]

Right.

You want to know what kind of tile is present at that spot

so you might need to go A* grid -> world space -> drawing grid

[hushed needle]

I didn't even know I could interact with my drawing grid.

lol

thanks

[heady iris]

i mean, it's your grid :p

[gray mural]

Is it possible to make myProperty.Length return whatever I want ?

myProperty is obviously a string property

[heady iris]

.Length will be a property from the string

maybe you can derive from the string class and override the .Length property? sounds weird

[gray mural]

it's impossible to change

[heady iris]

you'd have to return your own modified string type

[gray mural]

for example

private string foo
{
    get => bar;
    set => foo = value;
}

// foo = "fdsfsdfsdfsdfs"

// foo.Length; // returns e.g. 0 

[gray mural]

is it possible?

[knotty sun]

of course, overide the Length variable

[heady iris]

string is a sealed type

what are you trying to accomplish here

[gray mural]

I need it to return 0, when it is "\u200B"

[heady iris]

the non-printing space character?

[gray mural]

yes, zero-width space

[heady iris]

when the string is nothing but a zero-width space?

[gray mural]

yes

[heady iris]

are you trying to count visible characters here?

[gray mural]

my string is either something or "\u200B"

I need it to return 0 when it's "\u200B", otherwise just normal Length

...

if (value.Length == 0)
    value = "\u200B";

_textComponent.text = value;

...

[heady iris]

perhaps you can just keep value as an empty string

and then set the text component to contain a zero-width space anyway

[gray mural]

no.

[gray mural]

I access _textComponent through text

private string text
{
    get => _textComponent.text;
    set
    {
        if (value == null)
            value = string.Empty;

        value = value.Replace("\0", string.Empty).Replace("\u200B", string.Empty);

        _caretPosition = value.Length;

        if (value.Length == 0)
            value = "\u200B";

        _textComponent.text = value;

        AlignCaret();
    }
}

anyway, how do I override Length, as you have mentioned earlier?

[simple egret]

You can't, you're better off using an extension method (cannot make extension properties in C#) that returns your desired length, and call that one instead

[heady iris]

oh, true, extension methods would help here

you just couldn't clobber the original property (even if you had extension properties)

[gray mural]

ok, I simply check text now then

_caretPosition = (text == "\u200B") ? 0 : text.Length;

[heady iris]

yeah, there you go

of course, what if the user wants to enter a zero width space? :p

[gray mural]

I haven't thought of it first

[gray mural]

they cannot

zero width space does not exist on keyboard

[heady iris]

well, sure, but neither do emojis

[gray mural]

and user cannot copypaste in my input field

[gray mural]

so you say there is u200B in emojis ?

[heady iris]

ah yeah, if you can't even copy paste, then i guess it's not relevant

I just think it's good to not have any "special" strings

it'd be nicer to have a flag that tells you if the field is empty

[gray mural]

I need /u200B, because it's the only normal way to access TMP_CharacterInfo

[heady iris]

ah, so you need to have something in there

[gray mural]

yes, I do

[heady iris]

i mean you would still have a zero-width space in there; the "text" property would just be an empty string

[gray mural]

well, text returns _textComponent.text

I don't think I should seperate them somehow

and that's exactly what TMP_InputField uses

I have been investigating their code

m_TextComponent.text = processed + "\u200B"; // Extra space is added for Caret tracking.

why does Vector2.up, in the context of transform.translate gives me a "local" up (that points to the forward direction my transform is facing), but in the context of rigidbody.MovePosition gives me a "global" up (that points always "up" regardless of my transform's rotation)?

[small trench]

Doesn't matter where you use it
Vector3.up will always give you the global Up (Positive Y axis)

I think you are using local while using translate

It's transform.up that will give you the local y axis of the object

[leaden ice]

Because that's how translate works. It interprets the vector as a local vector

[jaunty sleet]

Hey guys, I have a script in my game called rhythm cube. I have a list of references to the copies of the script on my objects in the scene. I use this code: foreach (RhythmCube cube in rhythmCubes)
cube.StopAllCoroutines(); To try and stop all the coroutines the scripts are running, and it doesn't work. Any ideas?

[leaden ice]

If you look at the docs there's actually a second parameter where you can specify Space.World or Space.Local

[small trench]

https://docs.unity3d.com/ScriptReference/Transform.Translate.html

[leaden ice]

It's simply just because that's how they wrote Translate

[leaden ice]

Define "doesn't work"

[jaunty sleet]

It doesnt stop the coroutines. I can see that they are still running after this code has been triggered

[crimson atlas]

there's a MovePosition overload that allows me to tell it Vector2.up is local?

[leaden ice]

YOu'd have to show the code, clearly you've messed something up along the way

[leaden ice]

no

there's a Translate overload that allows you to tell it whether it's local or world space

read the docs

MovePosition is always in world space

#archived-code-general message

[small trench]

Just use transform.up
When you want to move it locally

[crimson atlas]

yeah i just did.
i was wondering if there's a classier way of achieving the same result but with MovePosition (to still process the physics stuff etc)

[leaden ice]

What uv said

[jaunty sleet]

Here is my code https://paste.ofcode.org/RCwxjUPcdUyaxdAA8C99bD

[crimson atlas]

but if i use transform.up won't it not do physics stuff (collider/rigidbody)?

i was told to use MovePosition instead of transform.Translate exactly for that reason

[leaden ice]

As per line 49 - all of your coroutines are running on THIS object, not the cubes themselves

unless there's some other coroutine involved

[jaunty sleet]

Oh, that makes sense

I guess the coroutine doesn't have to only run on the script its code is from

[leaden ice]

In other words - replace:

        foreach (RhythmCube cube in rhythmCubes)
            cube.StopAllCoroutines();```
with:
```cs
StopAllCoroutines();```

[jaunty sleet]

thanks

[leaden ice]

it runs wherever you called StartCoroutine from

[leaden ice]

transform.up not Vector2.up if you want local

[leaden ice]

transform.up is just a vector

it's just data

it doesn't do anything

you were told to use MovePosition instead of Translate

and that's still true

[leaden ice]

note that you can and probably should replace this code with:

rigidbody.velocity = transform.up * moveSpeed;```

MovePosition doesn't actually respect collisions properly

especially if this object is dynamic

[crimson atlas]

no need for the deltatime stuff in this case?

[quick elbow]

Should I use a CharacterController or RigidBody for an FPS game with vaulting, jumping, etc. Or is this simply a matter of personal preference?

[small trench]

But doesn't setting velocity mean it will override the physics calculations unity does?
Correct me if I am wrong

[leaden ice]

deltaTime will break it.

velocity already is a per-second quantity

[leaden ice]

which physics calculations in particular

MovePosition is much more disruptive to physics calculations than setting velocity

[crimson atlas]

it' kinetic btw. all manual move

[small trench]

Yes should always be using AddForce for non kinematic bodies

[leaden ice]

then either will work about the same

[crimson atlas]

wow it worked flawlessly

[leaden ice]

You know that the result of AddForce is just to modify the velocity?

[small trench]

Well the velocity calculations for that frame?

[small trench]

Yes but it does consider the mass?

[crimson atlas]

and it does make MUCH more sense that "setting velocity" is way better than just "teleporting" to maintain physics alright

[leaden ice]

sure but that's just a matter of math

deciding which velocity to set to

which you can do yourself too

[small trench]

[crimson atlas]

and solved my second problem which was this ugly conversion of "transform.up" into "new Vector2(transform.up.x, transform.up.y)" to correct some "amibuity" error VS popped up in some Vector2 vs Vector3 stuff

seems velocity will accept both?

[leaden ice]

this is because you had math involving a Vector2 added or subtracted from a Vector3

both V2 + V2 and V3 + V3 are valid

and it doesn't know if you want to convert the V2 to a V3 or vice versa

since both are valid

ultimately it doesn't matter but the compiler needs to just be told which

[crimson atlas]

so it's an "error" i could've just ignored?

[leaden ice]

no you can't ignore it

but you can solve it in many ways that are all equally valid

[leaden ice]

e.g.

rb.MovePosition(rb.position + (Vector2)transform.up);

rb.MovePosition((Vector3)rb.position + transform.up);``` would both work

[crimson atlas]

AHH i spent like 30 minutes trying <>, (), [], "as" lmao
didn't realize it goes before the variable

[leaden ice]

as would work too but is kinda sketchy here lol

rb.MovePosition(rb.position + (transform.up as Vector2));

although idk if that would get angry about nullables or something here

[final aspen]

https://hatebin.com/oigdrmybhr | https://hatebin.com/igfkydeuet i made these two scripts with help from youtube (thats why i want to make a drawer but its with the "doorOpen" or "doorClose" name) to make a drawer that open and closes i dooed the animations of it opening and closing and i maded this 2 scripts but its now working when i aim in the drawer my crosshair dont turn red and i cant press mouse0 to open it, pls help

[heady iris]

don't crosspost.

[final aspen]

i deleted other posts

i posted it here why i think this is not a beginners case

[crimson atlas]

now i wonder if there's some rigidbody.rotationVelocity i'm not aware of lol

[heady iris]

angular velocity

it's a float in 2D

[leaden ice]

yes it's called... that^

[crimson atlas]

omg https://docs.unity3d.com/ScriptReference/Rigidbody2D-angularVelocity.html

it's like i'm being introduced by a whole new world

[leaden ice]

loooking at docs == big brain

[leaden ice]

A new fantastic point of view

[crimson atlas]

lol

can i just set it like i set "velocity" won't it break anything?

[heady iris]

well, it's different from velocity...

[leaden ice]

it will make your thing spin

if you count spinning as breaking things

[heady iris]

it's a good trick

[leaden ice]

(or not spin, you know, depending)

[heady iris]

[crimson atlas]

oh yeah i just want to replace my rigidbody.rotation with this new guy

[leaden ice]

good idea

[crimson atlas]

dude i already feel like a pro coder

[heady iris]

position : velocity :: rotation : angularVelocity

scale : ?

actually, that's a good indication that scale is "weird" compared to the other two fundamental properties

[crimson atlas]

i'm even using overloads to avoid having to come up with weird names that would probably confuse me
Turn(CallBack context) subscribes to an input event and calls a local Turn(no arg) to make stuff happen

[heady iris]

i just read values directly from actions if I need them every frame

InputActionReference is lovely

[crimson atlas]

i explained that wrong though

i have a Turn(context) which just assigns values to a local var (just so i don't need to do that every single fixedupdate)

and another Turn (that is necessarily executed every fixedupdate) that grabs value from the local var

i guess all i did was take a check out of fixedupdate and have it happen only when value changes (inputaction event)

not a big deal i guess but personal progress

is it OK to link chatGPT "conversations" (the new feature they put out)?

in the subject of unity coding obvisouly

[sleek bough]

It's irrelevant here, especially in this channel.

[heady iris]

i would rather not be exposed to the spam machine

[crimson atlas]

it does get things wrong though lol
for example it also thinks (probably because of the variable names) that "collider" refers to ourselves and "otherCollider" to the 'other guy', however it's the other way around

[heady iris]

yes, because it's a large language model

it produces text that is likely to follow the prompt

ask it how to set the static friction of a 2D physics material

it will probably explain how to do that, even though 2D physics materials do not have static friction

(i would be impressed if it actually correctly responded that there is only friction)

[crimson atlas]

it is, and it probably uses its training with the unity docs to answer that kind of stuff
and from reading unity docs you really think "otherCollider" is the other guy.
only through you experience you learn it's the other way around

[heady iris]

well, no, you read the docs and they say what the variables mean

[crimson atlas]

what do you mean?

[heady iris]

you read the documentation. it tells you the answer.

collider:

The incoming Collider2D involved in the collision with the otherCollider.

otherCollider:

The other Collider2D involved in the collision with the collider.

[crimson atlas]

all the docs say to differentiate between them (besides referring to one as "collider" and the other as "other collider" is to say "collider" is the incoming one)
isn't incoming the guy which is moving?

[heady iris]

it's the one that is coming in and hitting us

i agree that otherCollider should have been named ownCollider or something

[crimson atlas]

exactly

to name something "otherCollider" while it's giving information about "myself" (the script's object) is like making an effort for people to confuse it

the other problem with the word "incoming" is
if A (script) is moving and hits B

B is the "incoming" guy (despite it being a static object)

is it the same with Collider (3D)?

at least it's described much more directly (and unambiguously)

[simple egret]

Oh hey, still on this? Yeah 3D is much more explicit on this even for contact points, thisCollider, otherCollider

[royal pulsar]

private Vector2 CreateRandomDestination()
    {
        Vector2 currentPosition = transform.position;
        float newX = Random.Range(-maxDistance, maxDistance);
        float newY = Random.Range(-maxDistance, maxDistance);
        Vector2 destination = new Vector2(newX, newY) + currentPosition;

        while (DestinationBlocked(currentPosition, destination))
        {
            newX = Random.Range(-maxDistance, maxDistance);
            newY = Random.Range(-maxDistance, maxDistance);
            destination = new Vector2(newX, newY) + currentPosition;
        }

        return destination;

private Vector2 CreateRandomDestination()
    {
        Vector2 currentPosition = transform.position;
        float newX = Random.Range(-maxDistance, maxDistance);
        float newY = Random.Range(-maxDistance, maxDistance);
        Vector2 destination = new Vector2(newX, newY) + currentPosition;

        if (DestinationBlocked(currentPosition, destination))
        {
            return new CreateRandomDestination();
        }

        return destination;

is one of these solutions preferred over the other?

i guess the recursion is doing the same thing

[heady iris]

recursion could eventually cause a stack overflow if it goes on for a long time

[knotty sun]

one is a potential infinite loop, the other is a potential stack overflow, neither of which are desired outcomes

[royal pulsar]

Oh yeah

So maybe a counter and after x tries it stops searching?

[knotty sun]

yes, also set a bool to know that it has 'timed out'

[gray mural]

does anyone know how words in TMP_Text are transferred to a new line?

perhaps "where?"

or in TextMeshProUGUI..

I guess in GenerateTextMesh()

[crimson atlas]

so when making a list of gameobjects that compose the player (snake segments in my case)
i see people using a list of "Transforms"
why not "GameObjects" or even "Rigidbodies" instead?

[gray mural]

because they change Transform's values

[simple egret]

It goes down to what is accessed a lot when using a list item. If you store GameObject but access their position, you'll have to do .transform.position every time

[gray mural]

and it sounds more logical to use Transform, not GameObect or Rigidbody

[crimson atlas]

so if i'm going to mess with velocity and angularVelocity instead of positions and rotations directly, i should probably reference a list of Rigidbodys right?

[neat echo]

ah cool! this sounds a lot easier than the shader solution i was thinking of

[gray mural]

yes

unless you don't need its Transform

[rocky laurel]

Is it possible to make a scene reload if a certain error pops up in the console? Let me know.

[vernal plank]

Texture propte = material.GetTexture("_MainTex"); this is doing what expected
material.SetTexture("_MainTex", extexture); this is not assighing the texture

w h y

Material material = AssetDatabase.LoadAssetAtPath(materialPath, typeof(Material)) as Material;

do i need render component

Am trying to change material texture with editor script

the material has a graph shader

but i dont wanna change the graph shader

i wanna change the material instance (its a normal mat)

[vernal plank]

bascilly the second one is retuning no error i wonder if i can debug it somehow and see what its doing

[crimson atlas]

is a static class adequate for implementation of a game manager (unique) class?

[vernal plank]

public class AssetDatabaseExamplesTest : MonoBehaviour
{
    [MenuItem("AssetDatabase/printmat")]
    static void SubFolderExample()
    {
        var folders = AssetDatabase.GetSubFolders("Assets/Silex-Materials_Pack/Textures");
        string foldvar = folders[3];
        string[] files =  Directory.GetFiles(foldvar+"/", "*.png", SearchOption.TopDirectoryOnly);
        string wellyay = files[0];

        string materialPath = "Assets/Silex-Materials_Pack/Materials/test/Mat_test.mat";

        Texture extexture = (Texture)AssetDatabase.LoadAssetAtPath(wellyay, typeof(Texture));
        // Texture2D extexture = (Texture2D)AssetDatabase.LoadAssetAtPath(wellyay, typeof(Texture2D));

        Material material = AssetDatabase.LoadAssetAtPath(materialPath, typeof(Material)) as Material;
        // Debug.Log(material);
        material.SetTexture("_MainTex", extexture);
        Debug.Log("well",extexture);

its editor script

its public class i guess

am trying to change the texture of a material

without effecting its shader

[potent sleet]

make the instance of the clas static

[rocky laurel]

how do i fix this? Bonzi is going forward, like he should, but Peedy seems to sink. They both use the same AI wander script.

[simple egret]

The green one has its forward axis pointing down, probably.

But also don't post your question in multiple channels, and especially don't repost your question every minute as soon as it gets buried by other conversations.

[urban berry]

I'm running into this really weird issue all of a sudden where Unity keeps tagging some of its own built-in components as not recognizable as monobehaviours

so prefabs lose their links to these scripts
It was happening to NetworkTransport before, and now it's happening to NetworkObjects
If I go into the prefab and reassign the script it "works" but as soon as I exit the prefab and it saves it, it loses the link on the prefab again and shows up as a missing script

[rocky laurel]

does this mean the forward axis is down?

The blue arrow (you're in rotation mode, switch back to move mode) points down

Probably

[rocky laurel]

is it pointing down

[simple egret]

Well use your eyes, definitely not

[rocky laurel]

lol

whats the issue then

this ones working, and its the same

[simple egret]

It points backwards though, but it might be a setup issue

[pliant locust]

does anyone here really good at coding C3 scripts?

c#

[urban berry]

The blue vector is the Z forward vector and should be pointing forwards, not back

[pliant locust]

anyone?

[simple egret]

Make sure your Move tool is in Pivot Local mode first. These are two buttons above the scene view

[tacit portal]

yoho friendly ppl

void OnTriggerEnter2D(Collider2D col)
    {
        if(col.CompareTag("Player"))
        {
            maxHP--;
            ShowFloatingText();
            if(maxHP == 0)
            {
                gameObject.SetActive(false);
            }
            
        }
    }

    void ShowFloatingText()
    {
        Instantiate(popUp, transform.position, Quaternion.identity, transform);
        Debug.Log(maxHP);
    }

the pop up text isnt showing for some reason. When i debug, then the hp is properly reduced with each hit, but only after it reached 0, does the pop up GO get instatiated, according to the hierarchy

It'll look like this

[rocky laurel]

still sinks.

[simple egret]

Never seen that happen, do you have editor scripts running anywhere? It might be just Unity freaking out once again!

[simple egret]

Post a screenshot with the arrows set up to Pivot / Local mode: #archived-code-general message

[urban berry]

Have you set up your pivot and coordinate mode yet?

[crimson atlas]

do i necessarily have to attach my "GameManager" script to a GameObject in order for it to execute its awake, start, update etc functions?

[urban berry]

yeah it's oddly specific

[rocky laurel]

this is pivot local

[simple egret]

Well the blue axis is up now

[urban berry]

please review my screenshot regarding pivot and coordinate system for the correct settings #archived-code-general message
make the settings match with what I posted there

[simple egret]

Meaning your AI wandering system actually pushes objects along the backward direction

[rocky laurel]

how do i change it

[simple egret]

These were probably exported from Blender, but as Blender is Z-up, it's broken

[rocky laurel]

oh

right

[simple egret]

You'll have to export again, with the correct axis settings

[simple egret]

What Unity version are you on? Might want to backup then upgrade / downgrade to see if that solves it

[urban berry]

I tried punching in "No monobehaviour scripts in the file" in a search and.... Apparently this is a thing! Well, I might be able to solve it with a Reimport All... Fingers crossed.

I'm gonna try this before doing the downgrade since it's a lower hanging fruit

[rocky laurel]

in blender, what next

[simple egret]

I have very limited blender experience

Ask there

[urban berry]

Okay... Well, let's look at the axes in Blender

blender uses a Z up

Unity uses a Y up

I think you can fix the problem with your export settings

[simple egret]

Yeah I remember seeing that, eh just try random combinations until it works

There's a 1/27 chance of getting it right the first time, good luck!

[potent sleet]

also this channel is for CODE related issues

this isn't one

[cobalt gyro]

if variables are private by default then whats the purpose of using the private keyword

[simple egret]

Being explicit about it

[urban berry]

yeah, he didn't know that going into this... we diagnosed it down to a modelling issue just now, maybe cut him a teeny bit of slack?

but here's something for @rocky laurel before you go to the modelling help department. This is in the export options. Muck with those.

[simple egret]

Did you know that classes and other types that are not marked with an access modifier such as private, are internal by default? So it's not always private, better be explicit about it!

[rocky laurel]

all working. thanks so much for your help!

[cobalt gyro]

Thanks for the info

[simple egret]

Oh that's actually simpler now, before you had X / Y / Z and individual configurations for each. Way more readable now in that version

[urban berry]

plus, by not making something public (and choosing something like private) it limits the scope of what OTHER objects can see that variable (and it can clean up your intellisense suggestions)

but, by default, public variables are SERIALIZED (meaning they show up in the inspector and these values are STORED in scene data or asset data

[pliant locust]

can i actually get help

[urban berry]

But you can add [SerializeField] to force this same behaviour upon any non-public members
and it will only work upon serializable data types

[pliant locust]

cuz im following the tutorial step by step and this one part isn't working

[urban berry]

ask your question, don't ask to ask!
it's faster that way

[pliant locust]

i dont understand dont ask to ask

it makes no sence

[urban berry]

don't ask if it's okay if you can ask a question

just ask your question

state the problem, let's see how your tutorial is breaking

we'll git er dun

[simple egret]

It eliminates the "can I ask you guys something" preliminary question that just wasting some time

It optimizes the time and space here, and as programmers oh boy do we like optimization

[pliant locust]

so basically it says to add a gird layout group to my toolbar ui image, i can add it, but when i duplicate my inventory slot (like the tutorial says) i doesnt do anything, when it should be spreading them out

oh so basically saying, can i get help, instead you state your problem

[urban berry]

okay, we need a screenshot of the UI (that is broken) plus a shot of your hierarchy, plus a shot of your inspector

we'll move from there

[pliant locust]

can i just send one full screenshot?

[urban berry]

go for it

[pliant locust]

not full photo but that's all ya asked for so thereeee

lol

[urban berry]

nono that's fine

[pliant locust]

when i duplicate the inventoy slot it should be looking something like this

but when i do duplicate it it does nowthing

nothing8

nothing***

[urban berry]

so they all get centered?

[pliant locust]

yeah

but when i duplicate it nothing happens

[urban berry]

well, what DOES happen is all of the slot objects are being tiled atop each other

may we see an inspector screenshot of the inventoryslot object as well?
