You could use this like:

Vector3 example = new(1, 2, 3);
Vector3 test = example.WithY(5);
print(test) // prints (1, 5, 3)```
#

Note you can only write extension methods and not properties. So you could write your own thing to create:

myVector.Example()``` but not```cs
myVector.Example```

#

Yeah, that makes me wonder how the .normalized property is added. I know it's a procedure of square roots and all of that, but I'm just curious on how I could do it, since as far as I know, for Unity it doesn't require the parentheses a method has

leaden ice
#

If you want to do the Distance thing as an extension to GameObject you could do this for example:

  public static float DistanceTo(this GameObject go, Vector3 target) {
    return Vector3.Distance(go.transform.position, target);
  }```
leaden ice
#

Unity's code looks something like this:

public struct Vector3 {
  float x, y, z;

  public Vector3 normalized {
    get {
       float magnitude = this.magnitude;
       return this / magnitude;
    }
  }
}```
#

that lets you do someVector.normalized

wise kindle
#

So it's a constructor?

leaden ice
#

no

#

it's a property

#

properties are just methods with cuter syntax

#

it's the same as if you just wrote

public Vector3 GetNormalizedVector() {
   float magnitude = this.magnitude;
   return this / magnitude;
}```
#

but it just has slightly nicer syntax to work with

#

under the hood it's exactly the same as a method though

#

(btw magnitude is also a property)

wise kindle
#

Got it. I'll check it out once I'm done with dinner

#

I actually have a static class called Generic where I put all my methods and variables I'm going to use across several classes or projects. For example, an enum for language selectors, a method to move towards a place, the formula for decibels based on sound intensity. Is that a good thing to do?

#

So that example you gave me is similar to what I already do

I'm genuinely lost.. why is this making my character jitter like crazy?

#

Specifically when I'm grabbing

#

I don't mean to be that person who wants people to fix their code but I'm just a bit dumbfounded is all. I don't know if I'm missing something obvious

leaden ice
languid hound
#

Even when the Rigidbody is kinematic it does this though

leaden ice
#

or perhaps you're colliding with the thing you're grabbing

#

when which body is kinematic?

languid hound
#

Sorry?

leaden ice
#

which Rigidbody is kinematic

#

the player?

#

The object being grabbed?

languid hound
#

Oh yeah no objects are being grabbed it's just thin air right now. The player rigidbody is kinematic while trying to fix this

leaden ice
#

Well you'd have to explain how your player movement works then

languid hound
#

This is literally all there is right now lol. I have an XR Origin with this slapped on it

#

Compound collider made out of a sphere collider on the camera and parented to the camera is a gameobject with a capsule collider

#

I tried being more "physical" and adjusting the velocity to get the rigidbody to the correct position. This partially worked but when it reached the target position it started to jitter even with no gravity affecting it

leaden ice
#

none of this code moves your character

#

except this

# 
transform.position += (leftHandGripPosition - leftPhysicalHand.transform.position).normalized;```
languid hound
#

Yeah

leaden ice
#

I'm really kinda trying to understand what that line of code is supposed to do

#

because that definitely looks like Jitter hell

#

why are you moving the player here

languid hound
#

It's a prototype I just want to get the player climbing something. I'm aware they're climbing thin air right now because they're only climbing what part of the air they grabbed

#

The whole idea is the transform will be offset by how far away the hand is from where it should be which should in theory correct it

#

And it does.. with a lot of up and down jitter

leaden ice
#

this code will move you by 1 unit every frame

#

which is absolutely going to cause a ton of jitter

#

and overshoot

#

and go back

#

etc

languid hound
#

But there's less than a unit between the grip position and the actual hand which is why I'm confused

#

Printing the distance gives like 0.3 off in the x

leaden ice
#

You're doing .normalized

#

which makes it 1

#

why are you normalizing

#

you definitely don't want to normalize

languid hound
#

Actually that's a good question why am I doing that

#

Hold on

#

Sorry I'm dead inside it's 12:26 right now and I've got a white box strapped to my head

#

Yes that did fix it thank you for pointing out a really stupid mistake

dry violet
#

I need to do a lot of calculations in parallel, how can I make it use the graphics card instead of the processor?

cosmic rain
dry violet
#

any tutorial?

cosmic rain
#

Many. Try googling.

chilly surge
#

If it's still the same question as the one you asked earlier, you should probably think about how to reduce the amount of workload rather than throwing more computing power at it.

dry violet
#

The problem comes because it calculates everyone's paths and when they are all calculated they move, if they don't wait it works perfectly

late lion
#

Moving computation to the graphics card makes less sense if you need the data back on the CPU. It's possible, but not ideal. You won't be able to get the data back immediately, it will have a 1-2 frame delay.

dry violet
#

okay thanks

I'm trying to figure out how to override a struct inside a class. Previously, I tried to use interfaces, but NativeArray can't hold interfaces. I'm trying to use the Job system, but I need to get data from all GameObjects with component in the level. I tried to move it into a struct, but I'm not sure how.

cosmic rain
wheat spade
# cosmic rain Can you provide some more details/code? As it's not entirely clear what you mean...

I have an abstract class that derives from MonoBehavior, a bunch of different classes derive from that class. There is an abstract method that returns a list of vector3s. Each derived class uses different math equations to calculate the list.
Then, in a separate block of code, I get all instances of the class in the level and combine the returned vector3 lists.
This is performance heavy since I have to iterate a lot, it froze the Unity Editor for a long while.
So, I wanted to convert my code to use the Job system. The Job system has strict requirements of thread-safe variable types. It mostly uses structs. I don't know how to move the calculations for returning a Vector3 list while being able to access all instances in a level. If I use interfaces, I can access them all but interfaces is nullable, so NativeArray won't accept it.

chilly surge
cosmic rain
#

Yeah, I'd also profile the issue properly.

chilly surge
#

Yeah for any performance related problems, the first step is always profiling than throwing random solutions at the wall and hoping it improves performance.

wheat spade
#

Am I able to use the Task system for one part and the Job system for another?

cosmic rain
#

Sure. As long as you can code it, everything is allowed.

wheat spade
fervent furnace
#

you can multithread the calculation part for each instance,
but multithread the combine part can make you code runs terribly slow unless the combine doenst mean append list to list (eg list.addrange(another list)).

chilly surge
#

Most Unity APIs also only work on the main thread.

I have a "LootSource" component that I was hoping to dynamically hook up to events in other objects by selecting them in the editor. For example I want to be able to place the LootSource on an enemy, and drag the "OnEnemyDeath" event in from the HP component to trigger the LootSource

#

But if I pull in the component that has the enemy death event it doesn't show up on the list, only functions do

#

well, variables too but not event variables

somber nacelle
#

make a method that invokes the event and subscribe that

river kelp
#

I'm not sure if I understand what you mean

somber nacelle
#

you cannot subscribe an event to a unity event in the inspector. so instead you create a method on the class that owns that event you wanted to subscribe and inside that method you just invoke the event that you were intending to invoke

river kelp
#

But it's not really the invoking that is the issue

#

Like, let's say a treasure chest is a loot source and an enemy is a loot source

#

I don't want enemies or the treasure chest itself to know about the lootsource component

#

So I want the loot source to add its own function as a listener on the event of the enemy

#

so when the enemy dies, it invokes the enemyDied event, which then should have the lootsource component as a listener, spawning loot

#

Even if I can't subscribe to the event in editor, if I could just get a reference to it I could subscribe to it in code

somber nacelle
#

so what specific part of that are you actually having trouble with? because your previous message implied you were trying to subscribe an event to another event

river kelp
#

I'm just trying to add a listener to an event that I select in editor

somber nacelle
#

show the method you are trying to add as a listener

river kelp
#

public void SpawnLoot()
{
}

#

and the event

somber nacelle
#

now show what you see in the menu for the event when you try to add that as the listener

river kelp
#

public UnityEvent zeroHPEvent = new UnityEvent();

#

well I can't do that because I don't have the event

#

the event isn't on the list of things I can place in the variable

somber nacelle
#

what do you mean

#

what variable?

river kelp
#

I want to select that event in the editor

#

I understand that is kind of dumb because this is not an event on this object but rather a reference to a different event on a different object

somber nacelle
#

it's not a reference to another event. you cannot drag an event like that

#

get a reference to the component and add the listener via code through the event on that reference, or just add the SpawnLoot method as a listener in the inspector for the zeroHPEvent

river kelp
#

Ah

#

so instead of trying to pass the event itself to the lootsource in order to runtime add the lootsource function as a listener

#

I just, in editor, add the lootsource as a listener on the event itself

somber nacelle
#

yes. or give the LootSource component a reference to the object that has the event on it to subscribe via code

river kelp
#

the lootsource would have to know about that object right

#

like, the lootsource would know about enemy death

somber nacelle
#

yes

river kelp
#

I think I'll do the other option of just adding the listener to the event

#

Thanks for the assistance!

# earnest meteor Hello. Can somebody help how to remove path from namespace "Game.AlpinoPlay.Scri...

If your creating scripts from within VS, then itll use the path as a namespace convention, if you create the script from Unitys Project browser, it will not use a namespace by default, and if that folder (or a parent folder) has an assembly definition file with a namespace, Unity will use that namespace when you create a new script from the Project browser - if its just that one file, you could just change the text to whatever you want that namespace to be called

somber nacelle

you can also set a default namespace for scripts created in unity in the project settings

Trying to get this object prefab to spawn in in the position 98x and 38y of the transform object but for some reason is spawning 10k away from that position. What is the issue with this?
prime sinew
#

as in, does it use RectTransform, or Transform?

hard viper
#

use debugger and breakpoint in the code to follow what the variables are doing

versed spade
#

Will have to take a look inot the debugger. Never used it for Unity

prime sinew
#

for UI, you should set the parent in Instantiate

#

then set the anchoredPosition of RectTransform of the object

# 

GameObject ShipItemObj =  GameObject.Instantiate(Shipitem, ShipSelectionContent);
ShipItemObj.GetComponent<RectTransform>().anchoredPosition = position;
#

I'm assuming ShipSelectionContent is a child of a Canvas

I'm making a battle system in my game and basically it kind of works like pokemon in the later gens, The player collides with a battle trigger, (a pokemon for example, or maybe comes into sight of a trainer) and this battle trigger would contain information such as which pokemon the battle should be with, the biome in which the battle is etc. But I think the best way to do this would be using putting the player into a 'Battle Scene' but obviously I'd have to somehow pass this info between scenes. How would i do this, and are there better ways to do it?

DDOL stands for DontDestroyOnLoad, and basically if you mark a GameObject as DDOL, it puts it in a special "scene" that persists alongside your other scenes

I'm trying to create a fade coroutine that isn't specific to any target value. However, it seems to get stuck because it's unable to reach it via Mathf.Lerp. I.e. it gets very close to 0 then bugs out and gives random string like 2.694687E-06

    {
        Color color = renderer.materials[0].color;
        while (color.a != targetAlpha)
        {
            color.a = Mathf.Lerp(color.a, targetAlpha, speed);
            renderer.materials[0].color = color;
            Debug.Log(color.a);
            yield return new WaitForEndOfFrame();
        }
    }```
leaden ice
#

Lerp really wants a duration, not a speed

jagged snow
#

ah ok yes I want a duration actually

leaden ice
# 
    private IEnumerator Fade(MeshRenderer renderer, float targetAlpha, float duration)
    {
        float timer = 0;
        Color color = renderer.materials[0].color;
        while (timer < duration)
        {
            timer += Time.deltaTime;
            color.a = Mathf.Lerp(color.a, targetAlpha, timer / duration);
            renderer.materials[0].color = color;
            Debug.Log(color.a);
            yield return null;
        }
    }```
#

something like this

knotty sun
#

also do not test floats for equality

jagged snow
#

ohh i see how it works now

#

thanks

#

is there a reason why its reaching the target alpha way before the duration?

I set the duration to 10 but its reaching from 1 to 0 in about a second

            yield return Fade(renderer, 1, _fadeDuration);
        }

    }
    private IEnumerator Fade(MeshRenderer renderer, float targetAlpha, float duration)

            renderer.materials[0].color = color;
            Debug.Log(timeElapsed);
            yield return null;
        }
        Debug.Log("TEST");
    }```
leaden ice
#

where do you set _fadeDuration?

jagged snow
#

in the inspector

leaden ice
#

Debug.Log duration see what it says

jagged snow
#

its showing the correct values as the inspector

leaden ice
#

Did you mess with Time.timeScale?

jagged snow
#

Nope its an empty scene with just two cubes and no other scripts besides this one

leaden ice
#

Ok can you show the codew that starts the FadeInAndOut coroutine?

jagged snow
# 
    {
        StartCoroutine(FadeOutObject(_renderer));
    }```
leaden ice
#

That's a different coroutine

jagged snow
#

    {

        while (true)
        {
            yield return Fade(renderer, 0, _fadeDuration);
            Debug.Log("Fade Complete");
            yield return Fade(renderer, 1, _fadeDuration);
        }

    }
    private IEnumerator Fade(MeshRenderer renderer, float targetAlpha, float duration)
    {
        float timeElapsed = 0;
        Debug.Log(duration);
        Color color = renderer.materials[0].color;
        while (timeElapsed < duration)

        }
        Debug.Log("TEST");
    }
}```
#

Here's the class

#

Everything seems to work as intended except that the target alpha is being reached in a fraction of the duration rather than syncing to it

leaden ice
#

seems fine to me... Add more logging I guess until you see what's wrong. I can't really see how this would go wrong other than the duration not being correct somehow, or if somehow the code is running more than once simultaneously 🤔

jagged snow
#

alright

leaden ice
#

basically log like:

Debug.Log($"Duration: {duration} TimeElapsed: {timeElapsed} Real Time: {Time.unscaledTime}");``` make sure they're corresponding
jagged snow
#

they are quite close

#

well importantly they're going up by the same amount

sorry there's an issue with the lerp still

jagged snow
#

ohhhh i got it

#

i know why

#

i had to store the initial alpha

#

trying it now

leaden ice
#

It should be

#

yeah

#

exactly

# 
private IEnumerator Fade(MeshRenderer renderer, float targetAlpha, float duration)
{
    float timeElapsed = 0;
    Debug.Log(duration);
    Color color = renderer.materials[0].color;
    float startingAlpha = color.a;
    while (timeElapsed < duration)
    {
        timeElapsed += Time.deltaTime;
        color.a = Mathf.Lerp(startingAlpha, targetAlpha, timeElapsed / duration);
        renderer.materials[0].color = color;
        //Debug.Log(color.a);
        yield return null;
    }
    Debug.Log("TEST");

yep works now thanks

#

Would be nice if we had math.remap in Mathf too.

Well you sorta can with Lerp and InverseLerp

#

but yea

Yeah... and various clamped/unclamped versions of these methods would also be nice.

#

What's the cost of MethodImplOptions.AggressiveInlining? Are we getting performance in exchange for larger binary executable files or something?

ashen yoke
#

yeah

leaden ice
#

Unnecessary use of this attribute can reduce performance. The attribute might cause implementation limits to be encountered that will result in slower generated code. Always measure performance to ensure it's helpful to apply this attribute.
I wonder what limits they're referring to

knotty sun
#

basically page caching in the CPU and Level 1 and 2 cache

ashen yoke
#

basically use it with small, struct/math methods where inlining benefits more than a call

#

works wonders

#

skips mem lookup, and scope push to the stack as i understand it, main benefit

chilly surge
#

I would think JIT is smart enough to optimize it by inlining already (and surely IL2Cpp even more so)

Use a DDOL singleton for the data which needs to pass between scenes. Not for other stuff.

you store the data in the ddol object and you have to prevent duplicate exists

This is my current script

In the previous scene you call Relay and then the data is accessible in the new scene

#

just make sure you're always setting it via:

BattleRelayInfo.instance.Relay(...);```

How do I incorporate Time.deltaTime into this rotation code?

transform.Rotate(0f, 0.0f, -0.5f, Space.Self);

I tried using transform.rotate(Vector3.right * Time.deltaTime) but it's not rotating fast enough.

#

*some speed

Can an object be essentially "stuck into" a terrain? I'm looking to make objects that can be attached to the ceiling, sort of buried into it, and then when it's dug at with a pick it will break out.

waxen blade
# fervent furnace *some speed

Turns out it's actually not rotating at all. I tried this:

transform.Rotate(Vector3.right * Time.deltaTime * 200f);

Doesn't matter what the speed is at the end, it's not rotating.

naive swallow
gusty aurora
waxen blade
#

I also tried

transform.Rotate(0f, 0.0f, -0.5f * Time.deltaTime, Space.Self);

This is also not rotating. @naive swallow the code is in an IEnumerator Start method in a while loop.

#

If I remove the multiplication of Time.deltaTime it does rotate again.

leaden ice
#

which is very slow

waxen blade
# 
            while (transform.position != targetPosition)
            {
                transform.position = Vector3.MoveTowards(
                      transform.position,
                      targetPosition,
                      speed * Time.deltaTime
                 );
                transform.Rotate(0f, 0.0f, -0.5f, Space.Self);
                yield return null;
            }
leaden ice
#

maybe you're just not seeing it because it's so slow

#

(it would take 10 minutes to rotate once at this speed)

waxen blade
#

Okay, I think you're right.

#

-0.5f works fine without deltaTime

leaden ice
#

you need to make the number bigger

waxen blade
#

But with it of course I need to really increase that value

leaden ice
#

and leave deltaTime in

#

yeah

#

think of it as "degrees per second"

#

which is what it is

waxen blade
#

Switching it to -200f gave me close to the original -0.5f

#

Just need to tweak it a little more. Thanks everyone.

leaden ice
waxen blade
#

Z is what I need, so that wouldn't have worked for me.

leaden ice

yep it would have needed to be Vector3.forward or Vector3.back

Hi guys, i have funny idea for game mechanic, but got into troubles trying to iplement it:
I'm recording sound from my micro in game to a clip. then my npc need to detect my voice tone from this clip somehow. I tried to get it somehow, but i realized i have no idea how to get this tone of sound. Please help me with advice what to do?

naive swallow
#

By "tone" do you mean literally tone as in the pitch or tone as in what sort of emotion the voice is conveying? One of them is really hard, the other is borderline impossible

dense pond
#

idk how to call it normaly like just main sound

#

like notes in music

fervent furnace
#

amplitude / frequency
notes is more like frequency

dense pond
#

yes but how to get this

dull glade
#

So I'm using the input comp in unity but I don't want player 2 to have his own screen but share it with player 1. But unity insists the player 2 must assign a camera. So what I want is split screen with 2 players per screen.

chilly surge
# dense pond yes but how to get this

Understand the differences between amplitude and frequency first, and decide on which one you actually want.
You can grab the audio data and then process it to get the one you want. Amplitude is just the volume, frequency you have to do a FFT and Unity has API for it IIRC.

How do I prevent input on UI using new input system?
Even if I switch between different input types, input system still lets me click on UI with mouse/keyboard/gamepad.

#

Is this the reason? That list of UI/Click etc?

leaden ice
#

yes

#

that's the reason

#

if you don't want any input on the UI to do anything you remove those or even the input module entirely

#

but then of course your UI won't be interactable at all

covert swift
#

i have a game where you can pick up things. but when you go near the wall, the object goes through it. Does anyone have a script or any ideas that makes it so it collides with the walls?

gusty aurora
#

increase your character's hitbox or add another hitbox in front

I want to click an UI button which starts a dialog scene, during dialog I use different set of controls(action map), but the UI is still interactable.

rigid island
leaden ice
covert swift
#

ok

leaden ice
#

or just disable the input module/event system

upper pilot
# leaden ice disable the UI action map

From what I read so far, only 1 action map is enabled at any point right?
So if I set "default action map" in player input system then it should automatically disable UI action map?

leaden ice
upper pilot
#

So multiple action maps can be enabled at any point?
How do I ensure that is not the case?

#

I thought thats the point of action maps tho.

leaden ice
#

The PlayerInput component has a concept of "current action map" but that's purely a PlayerInput thing

upper pilot
#

do I even need player input? 😄

leaden ice
#

are you using it?

#

You need it if you're using it to handle input

#

if not, you don't need it no

upper pilot
#

I do want to handle input somehow in script, like read current input to decide what to do, but UI input should be handled by Unity.

#

for example player movement is handled by me based on the input.

leaden ice
#

handled by you sure but using which technique?

#

There are several ways to use the input system^

#

anyway - the PlayerInput current action map will not affect the Input Module

#

so you'll need to disable the input module or disable the action map it's connected with

upper pilot
#

Either Using an Actions Asset or the Using an Actions Asset and a PlayerInput component
I have to read on those again, I forgot the differences 😄

#

ah yeah most likely 3rd option, without player input.

#

I dont want to setup events in the inspector.

#

Input Actions file has only 1 instance right?
So even if its attached to an event system, as long as I get reference to the input actions file I can disable/enable actions and it will disable/enable in event system as well?
or do I need to get reference to that action on the event system?

leaden ice
#

you can create as many instances as you like

#

it all comes down to your code

upper pilot
#

I want 1 instance, so I can disable/enable certain input.

# 

    CustomInput CustomInput = new();

  void Init()
  {
        CustomInput.UI.Disable();
        CustomInput.Combat.Disable();
        CustomInput.Overworld.Disable();
  }
leaden ice
#

So the issue with this snippet^ is you are using the generated C# class

#

and to do that you need to new() up your own instance of it

#

and that won't be the same instance that the input module refers to

upper pilot
#

I wasnt able to get proper reference to my input system so I could do CustomInput.UI
Do I have to get input action asset from EventSystem and do FindActionMap("UI");?

leaden ice
#

One alternative:

[SerializeField] InputActionAsset myAsset;

void Init() {
     myAsset.FindActionMap("UI").Disable();
     myAsset.FindActionMap("Combat").Disable();
     myAsset.FindActionMap("Overworld").Disable();
}```
#

you lose the nice autocomplete/compile time checking though

upper pilot
#

What is InputActionAsset?

leaden ice
#

I do wish they would provide a way to do like:

CustomInput CustomInput = new();
CustomInput.TargetAt(myAsset);```
upper pilot
#

nvm my VS got confused, but it figured it out

leaden ice
upper pilot
upper pilot
# 
        myAsset = MainEventSystem.GetComponent<InputSystemUIInputModule>().actionsAsset;
leaden ice
leaden ice
upper pilot
#

But earlier you said that they have separate instances

#

or was it something else

leaden ice
leaden ice
upper pilot
#

oh thats good then

#

so the asset file is like SO, its already an asset instance.

#

Hopefully I cant override input asset in script like I can SOs?

#

Tho that might be needed if I want to change input through game settings and such.

#

So does PlayerInput script do the same thing as I did above? i.e. Disable all action maps except "current action map"?

leaden ice
#

PlayerInput makes its own copy

#

and yes disables all but one map on that copy

upper pilot
#

yeah I cant do that unless I set this copy to event system.

public class PlayerInputController : PersistentSingleton<PlayerInputController>
{
    [SerializeField] InputActionAsset CustomInputAsset;

    protected override void Awake()
    {
        base.Awake();
        Init();
    }

    private void Init()
    {
        EventSystem MainEventSystem = EventSystem.current;
        CustomInputAsset = MainEventSystem.GetComponent<InputSystemUIInputModule>().actionsAsset;
        DisableAllInputs();
    }

    private void DisableAllInputs()
    {
        CustomInputAsset.FindActionMap("UI").Disable();
        CustomInputAsset.FindActionMap("Combat").Disable();
        CustomInputAsset.FindActionMap("Overworld").Disable();
    }

    public void EnableUIInput()
    {
        DisableAllInputs();
        CustomInputAsset.FindActionMap("UI").Enable();
    }
    public void EnableCombatInput()
    {
        DisableAllInputs();
        CustomInputAsset.FindActionMap("Combat").Enable();
    }
    public void EnableOverworldInput()
    {
        DisableAllInputs();
        CustomInputAsset.FindActionMap("Overworld").Enable();
    }
}

Is this correct way of doing it?

#

I should probably use PlayerInput, just need to be sure to set EventSystem to use same reference.
But if the above code is good, then I might as well stick with it 😛

I have a bug where calling DestroyImmediate(this) in Reset raises an error.

#

Can anyone confirm it is indeed a Unity bug not an issue on my side ?

rigid island

gusty aurora
#

private void Reset() { Object.DestroyImmediate(this); }

#

Does it also raise an error in your version of Unity

rigid island
gusty aurora
#

this is a component though

#

What else ? There is another way to remove a component ?

rigid island
#

even more reason to use Destroy

#

DestroyImmidiate is meant for Editor and removing assets

rigid island
gusty aurora
#

"Destroy may not be called from edit mode! Use DestroyImmediate instead."

rigid island
#

oh ur doing in editor?

rigid island
gusty aurora
#

Destroying object "" is not allowed at this time.

rigid island
#

hmm yea DestroyImmediate should work here since its editor..

#

I think Reset event might be the issue

rigid island

it makes sense though how can it reset something you're trying to destroy

#

sounds self-conflicting

I have a Tilemap that represents the ground in my game. I would like to be able to store some data on each of these tiles.

My first thought was to just do...

public class GroundTile : Tile { public bool isSandy; }

However, this prevents me from using different kinds of tiles. I'd like to be able to use RuleTile, for example.

#

I'm not sure how I should best handle this.

#

I could make an interface that I derive from in multiple "empty" classes

# 
public class GroundRuleTile : RuleTile, IGroundTile { public bool IsSandy => true; }
#

But then I have to repeat myself for every kind of tile I'd like to use

#

My other thought was to abandon making this a tile entirely, and to just have something like

# 
public class GroundElement : ScriptableObject {
  public TileBase tile;
  public bool isSandy;
}
#

But now I have to store a Dictionary<Vector3Int, GroundElement> and make sure it stays consistent with the tilemap

#

and I also can't paint ground tiles now

#

since...well, they are not tiles

heady iris
#

I guess I could invert things:

public interface IGroundTile {
  public GroundData Data { get; }
}

public class GroundRuleTile : RuleTile, IGroundTile {
  [SerializeField] GroundData data;
  public GroundData Data => data;
}
#

where GroundData is a bag of data

heady iris
#

(e.g. if i had to remember a health value for each ground tile)

#

ah, shoot, Tilemap.GetTile wants a TileBase, so I can't just give it an interface type

I am trying to run some code

        UpdateText(2f, "Rebooting.");
        UpdateText(3f, "Rebooting..");
        UpdateText(4f, "Rebooting...");
        UpdateText(5f, "Activating...");
        UpdateText(6f, "... Active ...");
        yield return null;
    }

    IEnumerator UpdateText(float Seconds, string Text)
    {
        yield return new WaitForSeconds(Seconds);
        renderText.text = Text;
    }

My question is does StartCoroutine work in VR? When I run this nothing happens.
If it does work what am I missing?

leaden ice
rigid island
leaden ice
#

You need to use yield return UpdateText(2f, "Rebooting."); to actually start it

#

or yield return StartCoroutine(UpdateText(2f, "Rebooting."));

ah i'm stupid >_< I just assumed that that UpdateText Already Did that.

How do I use PointerEvent in script?
Without adding PointerEvent component to the object

MonoBehaviour, IPointerClickHandler, IPointerEnterHandler, IPointerExitHandler

I have those on my class, that class is attached to an object with a Button component(button has graphic too)
None of these events fire when I hover/click on the button.(Button itself is not reacting to hover(color not changing))

#

Regular buttons work fine if I put them in the same place in hierarchy.

#

Ok so apparently Graphic has to be on the same component for a button to work :?

you can inherit from it and override those functions

#

So I have a DropTable that contains weighted items. It has a method "GiveItem" which causes it to randomly select an item by weight and return it.
I want to be able to pull the Random implementation out of the class so it doesn't have a dependency on Unity's Random class. Any tips?

calm hinge
ember mirage
rigid island
#

or make a bool

leaden ice
rigid island
#

set a bool and return out of the function just incase

#

but yeah making a method for when health gets removed is better

#

and / or method for Win condition to be called directly

calm hinge

#

so you can control what happens when number changes to what u want

{
  if (playerHealth <= 0) return;
  playerHealth -= amount;
  if (playerHealth <=0) 
  {
    sceneController.LoadScene("EndLose");
  }
//rest of the stuff
}
leaden ice
dawn nebula
leaden ice
#

Yes

dawn nebula
#

Meh, I can create a wrapper for it I guess.

leaden ice
#

I'm saying use an interface and provide different implementations for the interface

#

yes you'd need a wrapper to implement the iface

ember mirage
#

and make that playerHealth private

#

if you need to aaccess it elsewhere make a property public int PlayerHealth => playerHealth;

#

you can modify the TakeDamage if you have heals

ah

if you have a singleton

#

why are you doing scoreKeeper = FindObjectOfType<ScoreKeeper>();

#

the whole point is
static ScoreKeeper instance;

#

but should also be public

#

so you can access that specific instance like ScoreKeeper.instance.score

#

or use the method you have

#

but should still be public instance

#

score.text = ScoreKeeper.instance.GetScore().ToString("000000000");

I have a weird behaviour in my in my Editor right now, for some reason when i play, the objects in the scene are getting "refreshed" and it says: "This GameObject only exists at runtime", anyone else had this behaviour? If yes, is there a way to fix it?

Where did you get that SDK number from?

rigid island
#

what?

nimble cairn
#

SDK v 6 was installed with the C# extension to facilitate VS Code

rigid island
#

restart PC after installation

rigid island
#

should work with 8 too, but have you updated the Unity plugin to latest and everything

nimble cairn
#

Let me try that

rigid island
#

C# extension is old, now its C# DevKit for it

nimble cairn
#

I was about to ask

#

Do you use the dev kit

rigid island
#

well yeah anything I do in .NET needs it on VSCode

nimble cairn
#

So do I use Visual Studio Code Editor or Visual Studio Editor

rigid island
#

Use whichever want you want to use

I am currently rewriting my script to use preinstantiated prefabs instead of creating and deleting every frame. How can I move all colliders in results[] that are greater than the length of hits[] back to vector3.zero? ```cs
private void Start()
{
scannerVertical *= scannerHeight;
results = new Collider[8];
foreach (Collider i in results)
{
Instantiate(scannable, transform.position, transform.rotation, transform);
}
}
private void Update()
{
RotateRay();
int hits = Physics.OverlapCapsuleNonAlloc(player.transform.position - scannerVertical, player.transform.position + scannerVertical, scannerRange, results, layerMask);

for (int i = 0; i < hits; i++)
{
    Vector3 colliderPosition = results[i].transform.position;
    Vector3 desiredPosition = colliderPosition - new Vector3(player.transform.position.x, 0, player.transform.position.z);
    Vector3 position = this.gameObject.transform.TransformPoint(desiredPosition / (scannerRange * transform.localScale.x)/2);
    transform.GetChild(i + 1).transform.position = position;
}

}```

I don't think it matters here. You alternatively could subtract the amount you processed from the amount you need to process and have a second loop. The int i doesn't have to start from 0.

#

if you're doing mesh gen, usually you're implemeting most of it yourself

#

but, unity does provide some utility with colliders when it comes to convex hulls, so maybe if there's a way to use that

heady iris
#

Are you positioning objects at the points your query hit at?

#

I'm just confused by the scannable stuff up top

dense estuary
# heady iris I don't understand what this is doing.

Scannable is a icon that is displayed on a radar screen, the overlap capsule is being used to to detect objects within a radius of the player. First I allocate the array, then I create an icon for each collider in the array, in the for loop I calculate the positions of icons on the radar, then move the icons to the positions. My issue currently is that if an object is in the radius of the player, then leaves that radius, the icon just sits where it left off. My goal is to reset the position of the icon that's no longer being used to the center of the radar screen (Vector3.zero), when the hits array shrinks.

heady iris
#

Ooh, they aren’t colliders. That’s what was throwing me off

heady iris
dense estuary
#

Ik ow I can just set them back to Vector3.zero

#

But how can I detect if they are unused?

heady iris
#

The icon at index i is unused if i isn’t less than the number of hits.

dense estuary
#

Huh, thats makes sense, thank you very much.

I'm trying to change a TextMeshPro material preset's glow color.

Surely there's a better way than this:

MaterialPropertyBlock block = new MaterialPropertyBlock();

block.SetColor(ShaderUtilities.ID_GlowColor, Color.red);

textMeshPro.GetComponent<MeshRenderer>().SetPropertyBlock(block);
#

This isn't even changing the material preset, it's changing an instance of it! Very sloppy.

Hello everyone 🙂
I have a kinda weird discovery/question. We have a game on steam, everything is fine but the game will crash ONLY when players has this exactly GPU:
"Intel(R) Iris(R) Xe Graphics"

We have 3 bug reports with this and all 3 of them has this GPU. Is there something wrong with this GPU and Unity games?

#

other intergrated GPU works fine, only this Iris Xe model

It's not fully related to Unity, but maybe someone can answer this off-topic like question:
I can code pretty decently, but when I face a math related stuff - I'm completely lost even at basics of basic trigonometry problems, because in math I'm at level of "basic operations, some foundation of vectors and that's all, buddy", lol. Sometimes I don't even know what to google to find a good formula or decent algorithm, because of my poor math knowledge
Can ChatGPT be used for this type of tasks of googling or pointing to needed formula? Like just as source of constructing/finding formulas and then I'm just implement them in code by myself, not just "hey, write me some code to move a player"
Anyone using it like this within Unity development? I know that I can't trust anything like a saint word from ChatGPT, but maybe it can point me what to google next
I'm using 4th model version of ChatGPT, not free version, btw

#

yeah I've used chatgpt (and sometimes still do) and I have to like guide it through fixing a problem that it made...

i disagree, chatGPT is very helpful for find out about stuff, i use it almost all the time, just yesterday i found out about how i can use custom JsonConverters for my usecase from it

So if you can't ask a proper question then the answer will be horrible, like 99% of beginners will have

I have a different experience with using chat gpt to assist with learning a new technology and I can say that it helped a lot. You just need to understand how to work with it and what to be careful of.

but in that usecase asking about what math formulas to use where i think chatGPT can provide a good answer to where you can start your research

you're using the wrong component type for the GetComponent call. TextMeshPro is the 3d text object. you want TextMeshProUGUI

or you can use TMP_Text which both of those inherit from

it raycasts

dark tide
latent latch
#

I'm not too sure if it's a unique raycast of sorts, but it does raycasts in the scene and on the UI, so maybe it just uses what's available.

upper pilot
#

I see, is there anything special about raycast?

#

Compared to regular mouse events, or is raycast just Unity way of calling mouse events?

latent latch
#

Like mouseover? That probably uses raycasts too

upper pilot
#

I guess Unity is 3d, so it might need to "cast" forward into space to detect things

chilly surge
#

As for how Unity magically knows your component implements those interfaces without you registering in any way, I would assume it's some kind of reflection magic.

latent latch
#

One thing to note that if you do have a IPointerHandler in the world scene and on the UI and your pointer is over both, you will detect both IPointerInterfaces

chilly surge
#

It confused me when I learned about it too, then I just shrugged and moved on.

upper pilot
#

Is that the case if I implement 2 buttons without having custom IPointerHandler in my script?

latent latch
#

Nah, this is why I believe it uses multiple raycasts

upper pilot
#

oh

latent latch
#

I mean, it must use different raycasts because it's detecting at different locations of the scene

upper pilot
#

maybe raycast passes through(afaik there is a way to block that)

#

so it gets a list of objects it passed through

latent latch
#

On the UI it stops at first blocked

upper pilot
#

so anything in canvas(world space or regular) will be blocked at first element?

#

Thats good, I had the issue when I added onMouseStay/Enter for 2d sprites and those were detected even if UI covered them.
Since then I learned that there is a World Space Canvas and I use it since then 😄

latent latch
#

Yeah, so anything that has a box that you can tick "Raycast Target" or Blocks Raycast will be the target of that raycast.

latent latch
#

UI and Scene are different locations

#

It does a physics raycasts and some graphics raycasts from what it seems

upper pilot
#

What is a use case for OnMouseEnter/Exit for games?
Isnt it better to use world space canvas and draw buttons on top of your character sprites if you want to click on them, or is it more about using collisions for clicking 2d sprites in the game?

#

For 2D games ^

latent latch
#

Not too sure about 2D games, but UI does give you some components like buttons, but beyond that I don't see why you cant do a world space type of UI

somber nacelle
upper pilot
somber nacelle
#

use world space canvases for world space UI

upper pilot
#

Got it

#

I do use it for UI, its kinda hard to explain since the game world is static.
I have a list of zones(buttons) and you click on them for a character to "walk" towards them.
Character is 2D sprite, but the background/area buttons are on World space canvas.

#

I did it first using sprites, but I had issues with onMouseEnter events that would fire with UI covering them and I couldnt find an easy way to block the world space raycast(?) with UI.

#

Also using world space "ui" uses different scaling methods, all UI "sprites" have to be scaled like 200 times

somber nacelle
#

i personally prefer the event system interfaces over OnMouseEnter and the like. especially since i'm fairly certain OnMouseEnter doesn't work with the input system

upper pilot
#

I am still figuring this part out, I wish that I could somehow make it 1:1 ratio, but nothing works as of yet, so my current ratio is 100:1(world space canvas vs regular canvas)

somber nacelle
#

and your objects do not need to be UI objects to take advantage of those interfaces

latent latch
#

yeah no reasonto use OnMouse events when you have IPointer

somber nacelle
#

that's how you fix that

upper pilot
#

Meaning I need a specific set of sprites at higher resolution if I want to use them?

somber nacelle
#

huh?

upper pilot
#

so I avoid having to set their scale to 100 for them to be at "correct" size.

#

or in some cases its the other way around and I set scale of some objects to 0.01

#

Depends if I use canvas world space or just 2d sprites.

somber nacelle
#

again, the way you fix your issue is that you stop using UI to make your world space stuff

upper pilot
#

I am most likely missing something simple, but this is where I am now 😄

#

so I have to not use world space canvas, but instead use 2d sprites?

somber nacelle
#

yes. why would you use UI objects to make your environment in the first place

upper pilot
#

its not really environment, but I wasnt ready to use tilesets for this project as it doesnt fit.

#

Its really just buttons on the flat background.

#

only character is moving

#

but maybe I went too deep in the wrong direction 😐

#

so in order for my world space canvas(ignoring the fact that its environment) requires me to set up camera Size to 500 from 5(x100) in order to show properly.
Camera resolution: 1920x1080
World space canvas Background(child element of canvas) 4096x4096
With the above settings(camera size 500) my camera covers that canvas 1:1

#

Is there a way to go back to camera size 5 and have same ratio?
I was told yesterday that I should use w/e camera size I need, but it seems weird that I have to make it 100x bigger.

somber nacelle
#

and again, all of this could be avoided if you stop trying to make your game environment out of a world space canvas

upper pilot
#

ah ok I think that I know the issue I had.
My character sprite is 2024x2024

#

so I need to change its scale to 0.1 or so

somber nacelle
#

alright i guess we're just ignoring everything now so good luck with that

upper pilot
#

I mean this is not canvas character, its 2d sprite.

#

with camera set back to 5 size.

#

so its not UI

#

I dont see how else to resize character if its 2024x2024 file.

somber nacelle
#

change its pixels per unit setting in the import settings

upper pilot
#

Either importing at lower resolution or changing object scale right?

#

Thanks 😄

#

Setting it from 100 to 1000 fixed it

#

Is that proper way of doing it tho?

somber nacelle
#

yes (assuming you are referring to what i suggested and didn't just ignore that and continue referring to your own suggestion)

upper pilot
#

Thanks

#

That solves scaling issue for sure haha

#

2d sprite(not canvas, not UI) scale 1, pixel per unit of that image used in the sprite is set to 1000 from default 100.
it looks good now, since I believe the above means that 2024x2024 displays as 202x202 or so.

#

which covers ~20% of height in 1920x1080 camera setting

#

Which looks good, thats what I was stuck on, not understanding why it didnt scale the way I wanted.

#

base image was too big and pixel per unit was default 100

somber nacelle
#

don't think of it in terms of resolution. think in terms of units in world space. a 2024x2024 image set to 1000 pixels per unit takes up approximate 2 square units in world space

#

the amount of world space visible in your camera is dependent on the resolution of the game view and the orthographic size of the camera

upper pilot
#

size 5, 1920x1080

#

so 216 units in height?

somber nacelle
#

no not 216 units. 2 units

#

because 1000 pixels == 1 unit

upper pilot
#

ah

#

but that would mean the image should cover whole camera if the above is correct, but it covers about 15-20%

somber nacelle
#

no . . . it covers 2 units of world space

#

stop thinking in resolution, i am talking about world space

upper pilot
#

but the above means I have 2 units of world space in height?

somber nacelle
#

yes but that is irrelevant to the resolution of the game

#

because world space is not the same as screen space

upper pilot
#

How can I convert/compare those? so I know the settings I need in order for a character to take certain amount of screen space?

somber nacelle
#

world space does not change based on the resolution of the game. just how much of the world space you can see based on the orthographic size of your camera

chilly surge
#

Your coffee mug has the same physical size in the real world, no matter if you take a close up photo of it or a photo from across the room.

upper pilot
#

yeah I get that part, trying to figure some math.
If we agreed that 2024x2024 character at 1000pixels per unit takes 2 world space units, but it takes ~20% of 1080 camera at size 5, then there has to be a way to get the size of the camera in world space units.

somber nacelle
#

why

upper pilot
#

So when I import my sprites I know what pixel per unit to use for them to be visible in the game at correct size.

#

I might be doing it wrong 😐

somber nacelle
#

you are 100% thinking about this wrong

#

don't worry about the game's resolution. worry about the number of world space units you want something to take up. and you can clearly see how many units your camera can view in the scene view

upper pilot
#

Right, so is it wrong to ask: How many world space units my camera takes so I can compare it to units per pixel on my sprite?

somber nacelle
#

but you shouldn't be sizing those relative to the camera. you should size them relative to how big in the world you want them to be. then change the camera to view the correct number of units

upper pilot
#

Because the numbers we discussed dont seem to match on the screen

#

Right

#

I got that

somber nacelle
#

christ i'm done

upper pilot
#

I need something to use as a base size so I can import everything else relative to its size

somber nacelle
#

use the world space as the base size. 1 unit == 1 meter

upper pilot
#

Ok so this works after I changed camera size to 1...from 5.
camera size 1 seems to give you 1 unit in height(not sure about width)
So my character at 1000pixels per unit cover 1 unit.
Tho afaik height unit is calculated as camera height * 2, which makes more sens as my sprite is 2k resolution so 1000px per unit = 2 units.

#

Mystery solved, thanks. Math checks out <_<

#

I wont use camera as a reference of the size of my sprites, but I just wanted to understand where those numbers come from.

somber nacelle
#

So my character at 1000pixels per unit cover 1 unit.
except if your character is 2000 pixels tall then it covers 2 units. because as i have pointed out numerous times now, the resolution of your game view window is not relevant to the pixels per unit setting for your sprites. that setting affects how many pixels of the image occupy a single unit of world space

upper pilot
#

now I can import my sprites with 100pixels per unit and set camera to 50 size. if I got it right.

upper pilot
somber nacelle
#

do you though?

upper pilot
#

2000x2000 sprite, 1000px per unit = 2000/1000 = 2 units

somber nacelle
#

great! do you also understand that that measuremeant has nothing at all to do with your game window's resolution?

upper pilot
#

and camera size * 2 = height in units. meaning camera size 1 = 2 units in height

#

yes I look at camera size now, not resolution.

#

I will do last test by changing resolution of camera just to see if it still matches, just to be sure 😄

#

Resolution of the game*

#

Yep works as expected, thanks. All solved

#

800x600 makes character take full height too without changing anything.

#

Sorry for having you go through this, but this helped.

somber nacelle
#

yeah it's all solved until you come back with gigantic objects that are 50 meters tall and world space UI for your environment

upper pilot
#

At that time I will have another tool I can use to understand whats going on, so I probably wont make that mistake, and If I do I should be able to solve it.

Guys what is the cleanest way to make my async method die with my gameobject? It stops when exiting play mode alright but uh...
It doesn't stop after being destroyed.

Attaching a destroy cancellation token sounds about right, but thing is that I need to write this everywhere I want something to flash once-
Task.Run(() => highlighter.Flash(Color.white, 0.2f), destroyCancellationToken);
Which just doesn't sound appealing, especially since it also means that I'd better not forget to do that instead of calling it directly.

somber nacelle
#

using cancellation tokens is the cleanest way to stop your async methods/tasks

upper pilot
# upper pilot Resolution of the game*

And here was my issue too, I assumed that camera has resolution, but afaik its game settings that give you resolution. I got confused with Canvas which lets you set up resolution/pixel per unit and such.

pastel patio
somber nacelle
#

no, you don't need to use Task.Run and you shouldn't use that for anything that is going to touch unity's API since that schedules things on the thread pool. but you can (and should) still use cancellation tokens with your own async methods

chilly surge
somber nacelle
#

ah yeah, that too. the cancellation token for Task.Run is just for if the work hasn't started yet

#

your method would still to accept a cancellation token as a parameter to stop mid task

pastel patio
#

I thought that it just gets stopped when the source monobehaviour of the token gets destroyed?
Following Unitask logic it'd probably be a token source on each monobehaviour where the token came from?

chilly surge
#

The proper way to do cooperative cancelling, is for your highlighter.Flash method to accept an argument of cancellation token, and the method itself uses that cancellation token to do whatever its logic needs to do with cancelling.

pastel patio
#

Ah... Damn, literally has to check manually as before then

chilly surge
#

Task.Run also accepts a cancellation token, but it doesn't do what you think it does. Task.Run schedules something to be run, and that cancellation token is for cancelling the scheduling. So if a task has already finished scheduling and is running, the token does nothing.

somber nacelle
#

yep. although good news, if you are unity 2022+ monobehaviour has a destroyCancellationToken so you technically wouldn't even need to pass one in if the method you are calling is an instance method on the monoBehaviour

pastel patio
#

Though uh, why use destroy cancellation token if you have to do it yourself when you can just do: if (this == null) <- I tried that and it do return true when the behaviour's destroyed

chilly surge
#

That is also cooperative cancelling, it's just cancelling the scheduling of the task not the task itself.

somber nacelle
chilly surge
#

Not only that, cancellation token is required for cooperative cancelling.

pastel patio
#

Right... Okay I'll go read some extra stuff and just add those manual check ig

chilly surge
#

If your highligher.Flash doesn't call other tasks, then sure you can just keep null checking. But what if your highlighter.Flash needs to call something else?

#

The answer is by passing the cancellation token you receive, to that something else, so that something else also knows how to cancel.

pastel patio
#

Thanks guys, cya

pastel patio
#

Didn't think that it just always comes back down to that though :1

chilly surge
#

Yep.

pastel patio
#

Uh, just wanna confirm then, is it normal to add checks after every single await?

chilly surge
#

No.

#

When an async method accepts a cancellation token, as a convention it means that that method supports cooperative cancelling. So for a case like this:

async Task DoSomething(CancellationToken token)
{
    await DoSomethingElse(token);
    // should I check if token has been cancelled here?
}

Notice DoSomethingElse accepts a token, that means it supports cooperative cancelling, so the fact that that line of code has completed running, it means the token wasn't cancelled and you don't need to check it again.

#

If that DoSomethingElse does not accept a token argument, by convention it means it does not support cooprative cancelling, and once started it must run to completion with you having no way to tell it to stop, and in that case you would have to check the token after the await.

pastel patio
#

Uh, maybe my mistake is returning if the token is cancelled then, since what you wrote there hints that by convention cancellation of DoSomethingElse does not let the code pick up after the call...

chilly surge
#

If it's cancelled, you should throw OperationCanceledException.

#

Cancellation token also has ThrowIfCancellationRequested method you can call if you don't need to do any clean up.

#

But tldr:

// If your method supports cooperative cancelling, make it accept a token
async Task MyMethod(CancellationToken token)
{
    // Call other methods that support cooperative cancelling and pass them the token
    await OtherMethodA(token);
    // You don't need to check if token is cancelled here

    // Call other methods that does not support cooperative cancelling
    await OtherMethodB();
    // You have to check token here in some way
    token.ThrowIfCancellationRequested();
}
pastel patio
#

That does mean that it's used with try catch?

#

Since otherwise it might cascade undesirably far

chilly surge
#

Throwing OperationCanceledException is how tasks signal cancellation all the way up the chain, you are not supposed to catch it.

pastel patio
#

I don't remember why I wanted to do that in the past so... Alright '^^

#

Thank you Burrito, bye bye

thick terrace
#

i think it's usually fine to catch it in an empty catch block in top level locations like button click handlers, getting a bunch of OperationCancelledExceptions hitting the logs from ordinary stuff like the player clicking fast and cancelling previous actions is just unhelpful noise most of the time

#

for that exception specifically of course, don't catch everything haha

catch (OperationCanceledException) {
 // ignore
}
chilly surge
#

Yeah it's fine for top level since you are not bubbling up higher anymore.

I have added a overlap check so that none of the spawning items get overlapped on top of each other. Now I want to add some minimum distance so that they aren't very close to each other. Any tips on how can I achieve that?

   {
       bool isSpawnPosValid = false;
       int attemptCount = 0;
       int maxAttempts = 200;

       Collider2D[] colliders;


       while (!isSpawnPosValid && attemptCount < maxAttempts)
       {

           bool isInvalidCollision = false;
           colliders = Physics2D.OverlapCircleAll(spawnPos, radius);

           foreach (Collider2D col in colliders)
           {

               if (((1 << col.gameObject.layer) & layersEnemyCannotSpawnOn) != 0)
               {
                  
                       isInvalidCollision = true;
                     
                       break;
                  
                   
               }

           }


           if (!isInvalidCollision)
           {
               isSpawnPosValid = true;
           }
           attemptCount++;
       }

       // If no invalid collisions found, spawn position is valid
       if (!isSpawnPosValid)
       {
           Debug.Log("No valid spawn");
           return false;
       }


       return true;

   }```
pastel patio
#

Yeah, though I can't come up with an example of when I'd better use it which preferring to catch it, since getting destroyed is generally a bit of a complete ending to all functions?

My character keeps randomly getting stuck on something when moving. I've attached the player movement script, but what happens is if I keep moving left and right, my character will randomly just stop in a certain spot. It's velocity goes from 5 to fluctuating from 0-1.5 (or -1.5-0). The character gameobject has a polygon collider 2d and it's on a tilemap which has a tilemap collider 2d. any ideas as to why this is happenng?

void Update()
    {
        float moveDirHor = Input.GetAxisRaw("Horizontal");
        float moveDirVer = Input.GetAxisRaw("Vertical");
        Rigidbody2D rg = GetComponent<Rigidbody2D>();

        if (moveDirHor != 0)
        {
            if (rg.velocity.x < movementSpeed && rg.velocity.x > movementSpeed*-1)
            {
                rg.velocity += new Vector2(moveDirHor * (movementSpeed/50), 0f);
            }
        }
    }
plucky inlet
#

is that spot identifable or is it anywhere on the tilemap collider?

chilly surge
pastel patio
#

True

chilly surge
#

Although most of the time you can just do it with finally, or using if it's just cleaning up IDisposable.

pastel patio
#

Uh nvm, I might be looking too roughly there, need to doublecheck

#

Also best get and store the rigidbody instead of getting it each update

karmic stratus
pastel patio
#

Unless if that's what you intend of course

#

For the rest, no, I don't see why this script will cause such an odd behaviour

karmic stratus
pastel patio
#

Oh, reminds me, maybe it got stuck on the edge of a collider? Just a blind guess but I remember being annoyed about that before

#

Just try change your character's collider to a circular or capsule collider, if the bug doesn't happen anymore then it's definitely that

#

And honestly, you shouldn't use a polygon collider for your character unless if you have a good reason to

#

It's just extra weight for unnecessary precision, you see?

karmic stratus
#

yeah I see your point. switching to a circular collider seems to have fixed it, thanks!

pastel patio
#

No problem

karmic stratus
pastel patio
#

No matter how evenly put the floor is

karmic stratus
#

ahhh makes sense. thanks for the help!

#

guess I gotta be more careful with square colliders now lol

pastel patio

Good luck and have fun

# frail dust any ideas?

Note on quick glance: Rather then checking layers yourself, I'm quite certain you can add a layermask to the overlapCircle

#

Which filters out which layers you want and don't want to check for

#

And change layersEnemiesCannotSpawnOn to a layermask

#

(Sidenote: LayerMask is essentially representable by a series of bits that acts as true/false for each layer)

#

Also, for minimum distance you can just make the circleCast larger? If you want to do it more fancily you can make a value called like... Margin or so

dense estuary
#

Is there a way to find the angle between two directions resulting ina value between 0 and 360. Currently I am using Vector3.angle, but that returns a value between 0 and 180.

pastel patio
#

It doesn't quite make sense to get an angle difference between 0 and 360?

#

But... If you're just trying to do it clockwise exclusively

#

Some basic math should cut it

ashen yoke
#

it has potential to spend astronomical time looping in search of a position, a better approach is to use some sort of grid

pastel patio
#

It's not an inefficient approach if you ask me

#

It depends on how much of the spawn area is occupied

ashen yoke
#

its what you came to in the end i guess, basically you treat space as if it was a grid with some spacing, and you do flood fill on positions, adding them to a HashSet to see if this position was already checked

frail dust
frail dust
#

which spoils my concept of endless runner game

frail dust
frail dust
ashen yoke
#

i dont see anything complex in it, but its your choice

pastel patio
#

A grid could be necessary but if there's always a lot of free space... It's a waste of memory and unnecessary complexity

ashen yoke
#

there is no memory, there is no grid

#

grid is a position that is floored to some value

#

no 2d/3d arrays

#

all you have to do is select a cell size and any initial position round it to this cell size, this is the abstract grid

pastel patio
#

Well, even so, you're allocating a list/hashset to cache values when it could be solved in 1~5 tries, if there's a lot of space, it's insignificant difference and a small chance to become such a lag spike

hard viper
frail dust
#

guys lets not discuss the overlaps, just the min distance between items. I explain a bit more, its a car endless runner game.. Suppose there are 2 lanes, and 2 cars spawn, both are on different consequent lanes. But the y distance between them is so less that the player cant move within that gap

hard viper
#

but that only makes sense for 2D

pastel patio
frail dust
#

yes

hard viper
#

to distinguish 270 degrees from 90, you need some other info in 3D

frail dust
#

topdown

ashen yoke
frail dust
#

2d

hard viper
#

so it would need to be a function of at least 3 vectors, not 2

pastel patio
#

Uh sorry, zom is the dev, I was just guessing

frail dust
#

i think we all are on different pages lol

frail dust
hard viper
#

what I would do is define a function of Vec 1, vec 2, and orientation vector.

frail dust
#

Loup&Soup is discussing about other question ig

pastel patio
#

Anyhow, if you want distance between all enemies, a simple approach is to make a mask for enemies and increase the check range for that specific layer

hard viper
#

i’m talking to oddysey dev

frail dust
pastel patio
#

A tad bit more complex approach is to store and check the distance to each enemy, I guess

dense estuary
# hard viper but that only makes sense for 2D

I currently am comparing the angle of a rotating line and the angle returned by vector3.angle, to place an icon on a map when the lines rotation is a roughly the same value as the angle returned by vector3.angle. However, because the angle of the rotating line is always a value between 0 and 360, it causes an icon to spawn within 90 degrees of the line. So I need a way to find a value between 0 and 360 instead.

frail dust
pastel patio
#

There are of course even more "sophisticated" ways but it's likely gonna be overkill

frail dust
# 
    {
      if (((1 << col.gameObject.layer) & layersEnemyCannotSpawnOn) != 0)
      {
        if (col.gameObject.tag == "Cars")
        {
          // Check distance to existing car
          float distanceToCar = Vector2.Distance(spawnPosition, col.transform.position);
          if (distanceToCar < minSpawnDistance)
          {
            isInvalidCollision = true;
            break;
          }
        }
       
      }
    }````

I tried the distance check but this didnt work
pastel patio
#

Uh, really you should learn to use layermasks, it works for me and makes things look a whole lot simpler '^^

frail dust
#

Yeah I will try the layer mask

#

I have learnt a bit from codingmonkey

#

also i did use the layermask to do the OR operation for overlap check which worked

hard viper
frail dust
#

all i need to do is the min distance

pastel patio
pastel patio
hard viper
#

signed angles are more complex to parse in 3D, whereas they can be properly defined in 2D

frail dust
#

not overlapping, but close

pastel patio
#

Oh wait, first I should ask

#

Which plane is the world spread out in? XY or XZ?

frail dust
#

XY

pastel patio
#

Misunderstanding my bad

#

I thought XZ cus topdown

frail dust
#

its still a topdown tho

pastel patio
#

But then saw 2d collider and realized that I messed up

frail dust
#

u remember those 2d car racing games that were endless runner

hard viper
#

a lot of games keep Y as the axis in which you jump

frail dust
#

so what do you think ? @pastel patio

pastel patio
#

Looks about right

#

I don't really see why that piece of code messed up

fervent furnace
#

your spawn position (function parameter) is fixed and other things is fixed, then the result is deterministic

#

adding any non random thing wont affact the result, it is still deterministic

pastel patio
#

It's a piece of code to randomly place stuff

#

So there's a random value in it

#

Spawnposition and probably all the previous cars

frail dust
# 
    {
        while (true)
        {
            randomPrefabIndex = Random.Range(0, carPrefab.Length);
            GetRandomSpawnPosition();

            canSpawnHere = CheckForValidPosition(spawnPos);
            if (canSpawnHere)
            {
                Instantiate(carPrefab[randomPrefabIndex], spawnPos, Quaternion.identity);
            }

            float time = 0f;
            yield return new WaitForSeconds(time);
        }

    }

    private Vector2 GetRandomSpawnPosition()
    {

        randomLaneIndex = Random.Range(0, Lm.GetCurrentLaneCount());
        laneWidth = Lm.GetCurrentLaneWidth(randomLaneIndex);
        middleLanePosition = Lm.GetLanePosition(randomLaneIndex) + laneWidth / 2f;
        spawnPos = new Vector2(middleLanePosition, Random.Range(10.25f, 50f) + minSpawnDistance);

        return spawnPos;
    }```

Thats how i recieve the random spawn position everytime a prefab is selected

#

i say because we’ve been having a lot of big code blocks this morning

fervent furnace
#

btw try and error approach should work, just overlap circle with a random center, if no any other game objects then this is valid position

frail dust
#

yes

#

it basically tells

#

if it aint valid, then again choose a random pos

pastel patio
frail dust
#

it just doesnt change anything

fervent furnace
#

the spawnpoint didnt change during iteration

#

so iteration wont change anything

frail dust
#

yes but then it should break the loop

#

it will break the loop, increase attempt

#

if attempt = 200, then IEnumerator will select next prefab to be spawned

#

with a new random pos

pastel patio
#

Not after 200 attempts?

frail dust
#

it will go upto 200 attempts

#

its not changing the spawn pos

pastel patio
#

Uhm, wait, you're testing 200 times at the same place before switching location?

frail dust
#

yes

#

the next time a coroutine is called

pastel patio
#

What changes in each one of the 200 times tho?

frail dust
#

just booleans

fervent furnace
# 
public bool Method(int a){
  for(int iteration=200;iteraion>0;--iteration){
    if(a>10){return true;}
  }
  return false
}
```do you think than the iteration can change the result?
frail dust
#

that dictate whether the pos is safe to be spawned upon

pastel patio
#

Riiiight...

#

Really

#

Pick a random position each iteration

frail dust
pastel patio
#

You know why, right?

frail dust
#

So I call the GetRandomPos everytime it fails to find right spawn pos?

pastel patio
frail dust
#

if(isInvalidCollision)
{
GetRandomSpawnPosition();
}

pastel patio
frail dust
#

lemme just try it

hard viper
#

why are you doing multiple attempts

#

of the same code

frail dust
fervent furnace
#

btw there should be a deterministic algorithm to solve it by overlapping the circle on the lanes and doing a boolean subtraction on the mesh, so you can get some polygon areas, then the next step is to shrink the polygon by the radius of the new collider should be spawned to get the real set of spawning points (the shrunken polygons)
But this is so hard that i would still use try and error or copy other code.

hard viper
#

in general, I would change this function signature to:
private bool TryGetValidSpawnPoint(Vector2 proposedSpawnPos, out Vector2 validSpawnPos)

#

if it fails, return false.
If succeeds, return true, and out the valid position

frail dust
frail dust
#

but the number of attempts isnt the main problem rn

hard viper
#

this is just a general architecture thing

frail dust
#

yeah i agree

hard viper
#

In my code, I have a CheckSpawnBlock method that solely checks if a given position is valid for spawning, or if the thing is spawnblocked

#

i do not iteratively try to spawn it anyway at a few different random positions if it fails

#

it is private bool CheckSpawnBlock(Vector2 pos)

frail dust
frail dust
hard viper
#

if I needed to try multiple iterations, I would make a separate method that calls CheckSpawnBlock at a couple of locations, using the signature I said above; TryGetValidSpawnPos

#

basically, split the check from any sort of iteration

#

these are two totally separate tasks

frail dust
#

thats true

hard viper
#

TryGetValidSpawnPos might need multiple different parameters later for things like search range, number of iterations, RNG seed, etc.

#

all of this is separate from checking validity of a specific spot

#

my recommendation is not to use any RNG, but a hard coded array of offsets to test at.

#

like, first check spawn point, then spawn point + (0.1, 0), then spawn point + (-0.1,0)….

frail dust
#

more like a linked list

hard viper
#

any IEnumerable would work

frail dust
#

in which i give it a range of y positions to select

hard viper
#

i would not try very hard to force something to spawn if it is really blocked tho

#

depends on how important it is for it to spawn

#

if it is a boss or something, it should probably force its spawn, and try to shove out things that are in its way

frail dust
#

understood, i will retry my approach

hard viper
#

yeah. i wouldn’t even try attempts at all. If blocked, block it. If it’s important, spawn it anyway, and push shit out of its way

#

Unity’s physics engine should do decent depenetration for overlapped crap anyway

Hi all - I'm looking for guidance on recreating a mechanic I've seen in many different games.

#

These little characters follow the main player, but they recreate his movements and always remain at a distance.

#

How can this be done? I tried getting delayed positions using a TrailRenderer, but it's been extremely finnicky so far. There must be an easier solution.

latent latch
#

seems like just queueing a bunch transformational info over some duration

#

could do a bunch of matrix4x4s

cosmic rain
#

Just position and rotation would probably be enough.

craggy veldt
coral cosmos
#

Pizza Tower! It's my favorite new game from last year. I'd recommend it.

craggy veldt
coral cosmos
latent latch
#

lerping and adding some delay between each would be fine

#

similar to how you'd do it with animation curves

craggy veldt
#

you dont need to

#

it's just dampening

#

the ease in/out will be added automatically

white perch
#

Hi guys, if u write documentation of your projects - where do you do that?

coral cosmos
#

github, probably

latent latch
#

I mean, they seem to be not just lerping towards the main character, but following a route

coral cosmos
latent latch
#

so* there needs to be some positional caching

cosmic rain
coral cosmos
#

Is that done on the player itself? Populating and repopulating an array of positions?

craggy veldt
# coral cosmos These little characters follow the main player, but they recreate his movements ...

you can copy the formula here for the ease in/out.. there's a TypeScript version in it, you can just convert it to c#, they're quite similar it will work https://easings.net/

Easing functions specify the speed of animation to make the movement more natural. Real objects don’t just move at a constant speed, and do not start and stop in an instant. This page helps you choose the right easing function.

coral cosmos
#

Whatever it is, it's gotta be light on performance.

ashen yoke
#

in that video i think there is a combination of methods, when player is moving they use the stored positions with offset, while standing they switch to a lerping to a point behind the player

coral cosmos
#

Yeah, that second bit I can take care of fairly easily.

#

It's just lerping to the player with an offset.

#

The former is more difficult, as each follower needs a specific delay.

craggy veldt
#

it's not linear, you need to smooth dampened them

ashen yoke
#

in the video the delay seems to be a fixed value for every follower, like 0.1 seconds, because it seems to scale with speed

coral cosmos
#

Yep.

latent latch
#

well, t being some distance constraint because you don't want them to fall behind if the character is too far ahead

#

so yeah not exactly linear (actually if speeds are the same then it should be very much linear)

coral cosmos
#

Well, they'll always catch up I think.

#

It's not like the player going too fast will ruin it. A distance cap is something I can put in later if I feel it's necessary.

ashen yoke
#

if you have some circular buffer where a cursor is the player, and you sample player position at known intervals, in FixedUpdate for example you will know how the index offset in the buffer corresponds to time

#

so if its sampled every 0.02 seconds 5 indeces difference is 0.1 second, so each follower just looks at the index that corresponds to it

craggy veldt
#

it's just smooth damp + offset 😅

transform.position = Vector3.SmoothDamp(transform.position, targetToFollow, ref velocity, speed);
#

toy around with the velocity

#

you'll get the same effect as that video

ashen yoke
#

problem with smooth damp is that it will introduce that rubber banding effect with speed, it works but as seen in video some followers are left very far behind, may be desireable idk

craggy veldt
#

you can do exactly that, you just need to set the velocity value small enough

#

either way you can make your own from the website I linked above

#

just convert the math formulas to c#

ashen yoke
#

there probably is an easing lib for c# on github

craggy veldt

so check your division there

shouldnt normal be already normalized?

#

you also dont need -1 length-1 i think

#

rather total / length

#

for an average if you are doing it that way

There's a few problems doing it that way as you can get a cluster of points in one position despite a bunch of other areas.
