[sullen drift]

might came out

[pliant rivet]

okay

did you use any learning resources?

[fleet gorge]

literally just make games and publish them

these things are remembered through practice

[pliant rivet]

i have some. i have one on the playstore too

[fleet gorge]

then you're more than prepared

[sullen drift]

sometimes. all the answers are right, but 1 answer is the most efficient and optimize

[pliant rivet]

i see

[fleet gorge]

they test a bit of version control

[pliant rivet]

they ask about unity services?

[fleet gorge]

that's for the other cert, unity developer

which in addition to everything above also tests on unity cloud, deployment and other services

not as many coding qns

[pliant rivet]

got it. they will test on 2022 lts right?

[fleet gorge]

that I'm not sure

[pliant rivet]

okay

[fleet gorge]

even if they do you'll figure it out

[pliant rivet]

thanks guys you have been a real help to me :>

[fleet gorge]

🎊 good luck for your test

Are you doing this for yourself or is your organisation sponsoring you?

[pliant rivet]

myself

[fleet gorge]

Ah I see

I'm just gonna say that employers won't care about the cert that much, they care more about what you already have out there

[pliant rivet]

i am actually in third year - college rn and i have a semester break so i planned to give the exam

[pliant rivet]

yes i have seen people comment that a lot, i have projects but i don't have certifications..

i am also learning unreal side by side

[dense swan]

    void Start()
    {
  #if UNITY_RELEASE
        // Only destroy FpsCounter in release builds.
        Destroy(gameObject);
  #endif
    }

I'm trying to run script only on release builds. but this doesn't seem to work. Maybe I don't understand what 'release' even mean for unity.
How do I run script only if I ran the game from editor OR from build with "Development Build" checked?

[simple egret]

UNITY_RELEASE is not a symbol defined by Unity so the code in the #if will never be compiled. See https://docs.unity3d.com/6000.0/Documentation/Manual/scripting-symbol-reference.html for the available symbols

Not Editor nor development build should be a #if !UNITY_EDITOR && !DEVELOPMENT_BUILD

[wary veldt]

Why is there no stacktrace for some errors?
For example, now I have error
Can't destroy Transform component of 'Button'. If you want to destroy the game object, please call 'Destroy' on the game object instead. Destroying the transform component is not allowed.
I know that I can simply inspect all of the Destroy calls, but in a big project it would be a real problem
Is there a way to get the exact line problem occurs?

[dense swan]

it works, thanks!
It looks like my question is wrong, but you have given me a correct answer despite that.

[steady bobcat]

I use #if DEBUG for editor/debug builds

[thin aurora]

Because a stacktrace would be for an exception. This is not an exception but rather an error logged internally

You can most likely click the error here to open up the gameobject related to this.

[wary veldt]

nope, it won't do even this

[thin aurora]

That's shitty Unity debugging for you

It's very unclear

[wary veldt]

That's really strange to let you destroy transform as well, just to send an error each time you actually do this

[hexed pecan]

It doesn't destroy the transform

A transform is always needed on a gameobject

Weird that it the error does not have any context though. Maybe the object is already destroyed by something else 🤔

[wary veldt]

sure not, I've already tested it in a blank project

[wary veldt]

Oh, now I see, you can pass Transform as it is a component too, well, it makes a little more sense for me now

[hexed pecan]

Yep!

[mossy shard]

In a grid, how would i find the closest node to a world position without iterating trough each node and calculating the distance between the current node and the world position (inefficient)

[hexed pecan]

You would just remap the world coordinate into grid coordinates with some rounding (floor) and perhaps addition or subtraction if the grid is offset from the world center

I actually just wrote something like that...```cs

    [MethodImpl(MethodImplOptions.AggressiveInlining)]
    private Vector3Int WorldToCellCoord(Vector3 worldPos)
    {
        worldPos /= gridSize;
        return new Vector3Int(Mathf.FloorToInt(worldPos.x), Mathf.FloorToInt(worldPos.y), Mathf.FloorToInt(worldPos.z));
    }

    [MethodImpl(MethodImplOptions.AggressiveInlining)]
    private Vector3 CellToWorldCoord(Vector3Int cellCoord)
    {
        return new Vector3(cellCoord.x * gridSize, cellCoord.y * gridSize, cellCoord.z * gridSize);
    }```

This one does not have offset

@mossy shard Anyway, unity already has a Grid component that handles this stuff for you:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Grid.html

[mossy shard]

oh

thank uuu

[tawny spoke]

so like. Got an existing project, has 1 sln and 6 csproj files. its meant to produce a few dlls with specific guids, to serve as 'stubs' against the vrchat sdk package. I wish to extend it with some additional data types added in later sdk versions. I can open it in jetbrains rider and do code editing/etc, but it doesn't have reference to any of the unity dlls. if I put the existing project into a unity project and open it it ends up destroying the dll separation and bundles them all into one. Am I missing something here?

(for reference: linux)

[visual fjord]

Question general
If I use C# events for a differences systems, Could I do that a gameobject(1) shoot an event to other gameobject(2), this could shoot an event to gameobject(1)?

It's right?

[leaden ice]

GameObjects themselves don't do much of anything

Your scripts can do whatever you want

[compact spire]

Hey everyone, been struggling at this one for a bit. I'm trying to create a grid based placement system for different shaped blocks. If I use a cube collider on each one that fits the cells of the grid, how do I resolve which "side" is being looked at when attempting to place one block on another. I guess this simplifies to, how do I determine which side of a cube collider is being hit when it's hit by a ray?

[leaden ice]

Inspect the normal vector from the Raycast hit and compare it with the 4 cardinal directions

[compact spire]

Interesting

I think that's enough for me to go on, thanks @leaden ice

sweet that worked

[wheat spruce]

Why is my Spline instance persisting even after I stop running the game in the editor?

  public class ZenComponent : MonoBehaviour
  {
    public static Spline PerimeterSpline;
    // Spline sets the perimeter of the garden environment

    private void Awake()
    {
      PerimeterSpline = new Spline();
    }

    private void OnDestroy()
    {
      PerimeterSpline = null;
    }

    private void OnApplicationQuit()
    {
      PerimeterSpline = null;
    }
  }```

[heady iris]

this doesn't have an [ExecuteAlways] attribute on it, does it?

[wheat spruce]

I have a class that uses the spline to instance those box colliders. When the spline first gets created, that box-collider class doesnt construct because at that moment, the Spline hasnt been fully constructed. Stopping the scene and restarting it, the colliders do get built because at that point, the spline is pre-existing

[heady iris]

and do you have Domain Reload disabled?

[heady iris]

This would affect when Awake gets run

[wheat spruce]

and no, theres no attributes on anything

[heady iris]

Can you show the code that's constructing the box colliders?

[wheat spruce]

  public class SplineComponent : MonoBehaviour
  {
    public HandleComponent HandlePrefab;
    private List<HandleComponent> _handles;

    private Spline _spline => ZenComponent.PerimeterSpline;    //SplineComponent was what construct the spline before

    private void Update()
    {
      if(_spline == null)
      {
        return;
      }

      if(_handles == null)
      {
        CreateHandles();

        void CreateHandles()
        {
          _handles = new();
          foreach(var point in _spline.Polygon.Points)
          {
            var handle = Instantiate(HandlePrefab, point.ToVec3(), Quaternion.identity, transform);
            _handles.Add(handle);
          }
        }
      }

      for(int i = 0; i < _handles.Count; i++)
      {
        _spline.SetPoint(i, _handles[i].transform.position.ToVec2());
      }
    }
  }```

[heady iris]

The SplineComponent sets the spline points after it tries to create the handles, so I would expect this to never work correctly.

given the "ZenComponent" name -- is Zenject involved here?

[wheat spruce]

SetPoint? apologies, its a badly named thing. Its actually SetPointPosition

just uses the handles position to drive each point on the spline

[heady iris]

it's using the spline's points to create handles, and then using those handles to set the spline's points..?

[visual fjord]

Yeah, I know, but, It's correct my logic?

[heady iris]

it's a bit self-referential

[wheat spruce]

  public class Spline
  {
    public PolyShape Polygon; // control points

    public Spline()
    {
      Polygon = new PolyShape(8, 4f);
    }

    public void SetPoint(int index, Vector2 vertex)
    {
      if(index >= 0 && index < Polygon.Points.Length)
      {
        Polygon.Points[index] = vertex;
      }
    }
  }```pretty much

[heady iris]

Oh, this has nothing to do with the Splines package, okay

that's where the shape comes from

[wheat spruce]

yeah, thats what im fixing in this refactor

[heady iris]

I would check if OnDestroy or OnApplicationQuit are actually being executed

(along with Awake)

[wheat spruce]

yup

[heady iris]

Is this consistent across every Play Mode entrance and exit?

[wheat spruce]

if I make any changes to the code, it does clear the instance

[heady iris]

Notably, with Domain Reload off, you may see differences on the first Play Mode entrance after a recompile

[wheat spruce]

the video was shown directly after I saved the C#

[heady iris]

(since a domain reload does happen at that point)

[wheat spruce]

it does that the first time, then every other time I enter play the handles get created

[heady iris]

hang on, I have a really dumb idea

this doesn't make any sense because the Spline type is non-serializable and it's in a static field

[wheat spruce]

thats interesting. changed the setting to this, and even after I make changes to the code, it always creates the handles without issue

[heady iris]

but can you slap [System.NonSerialized] on that static field anyway

[heady iris]

That's the opposite of what I was expecting!

[wheat spruce]

same

[heady iris]

well, actually

it's consistent if my crackpot theory is true

[wheat spruce]

[System.NonSerialized] creates handles fine too

[heady iris]

so with domain reload disabled and that attribute on the Spline field, you get the correct behavior every time?

[wheat spruce]

seems like it

[heady iris]

and if you remove the attribute, the handles don't get created on the first play mode entrance after a recompile?

[leaden ice]

What do you mean by "correct"?

If it does what you want it's correct

[wheat spruce]

which makes no sense because if the spline was always being created before the handles get a chance to read the spline, then surely if NonSerialized means what I'd expect, the handles should never be created correctly

[heady iris]

yes, this doesn't make sense for multiple reasons

[wheat spruce]

yeah

[heady iris]

Unity will serialize fields that you haven't actually told it to serialize

for example, private fields

It does this so that you can see them in the inspector's debug view

I had a problem once where it was putting garbage into an InputAction field

so instead of a null, it was some weird default

I fixed that by explicitly telling Unity to not serialize the field

But this situation is different for quite a few reasons

your Spline class isn't serializable at all and that field is static

And even if Unity was somehow trying to serialize the field, it would run the default constructor of Spline, which would populate it correctly

I'm guessing the handles aren't appearing on the first run because the spline has zero points in it

Is PolyShape serializable?

[visual fjord]

Ok

[wheat spruce]

no

let me put everything back to when the handles didnt get created the first time, I want to step through and see whats happening

[heady iris]

Log the number of points in the spline's polygon when you try using it in SplineComponent. You should see a zero when the handles fail to appear

But that also doesn't make sense, because the Awake method in the ZenComponent should run first

[wheat spruce]

ooohhhh

noticed it skips past this on the first ever run (when the handles dont get created correctly until the next playmode)

then on the second run, somehow they begin as null

[heady iris]

the Awake method on ZenComponent is running first, isn't it?

[wheat spruce]

let me check

[heady iris]

or is ZenComponent spawning in a bit late?

It feels like you have something that runs outside of Play Mode that's putting a bogus value into that field

[wheat spruce]

SplineComponent calls first

I think?

[heady iris]

right, but SplineComponent is doing its work in Update

[heady iris]

find all references to ZenComponent.PerimeterSpline in your project and make sure you do not have anything else that sets it

I don't see any way for a value to sneak in there

[wheat spruce]

only SplineComponent references that spline, im refactoring to put all my objects into one location (ZenComponent)

[heady iris]

AFAIK Unity doesn't serialize static fields under any circumstances

but given that the NonSerialized attribute had an effect, hm...

[wheat spruce]

basically all these parts are in several classes, now that theyre all working, the refactor will tidy stuff up

[heady iris]

(did you verify this with your IDE?)

[warm rover]

Is there anyway to convert a obj to a navmeshsurface

[wheat spruce]

honestly, I might go back to SplineComponent being the thing that constructs the Spline, not the ZenComponent

[heady iris]

this question does not make sense -- perhaps you're asking how to add a NavMeshSurface to an existing game object?

[wheat spruce]

probably was silly to have Zen construct the Spline

[heady iris]

it's a component just like any other; you'd use AddComponent to attach one at runtime

[wheat spruce]

all seems good now!

public class SplineComponent : MonoBehaviour
{
public HandleComponent HandlePrefab;
private List<HandleComponent> _handles;

public static Spline PerimeterSpline;
public Spline GetSpline() => PerimeterSpline;

private void Awake()
{
  _handles = new();
  PerimeterSpline = new Spline();
}

private void OnDestroy()
{
  PerimeterSpline = null;
}

private void OnApplicationQuit()
{
  PerimeterSpline = null;
}```Now the spline is definitely being erased after the scene stops, and the handles get created without any issue

[rugged pond]

Hello, can someone give a tip how to check if i click on another inventory slot to change active one and if i dont do it to execute another part of code?

Here is what i already have

private void Update()
{
    if (InputUtilities.PressButton("Use") && isActive)
    {
        // try to change slot

        // otherwise use item from current slot
        UseItem();
    }
}

---

public void OnPointerClick(PointerEventData eventData)
{
    if (eventData.button == PointerEventData.InputButton.Left)
    {
        OnLeftClick();
    }
}


public void OnLeftClick()
{
    inventoryManager.DeselectAllSlots();
    selectedSlot.SetActive(true);
    isActive = true;
}

[wheat spruce]

@heady iris what do you think the problem might have been? the behaviour it was doing before seemed really bizzare

[heady iris]

There was clearly an invalid Spline object stored in that static field after recompilation

I just don't see any reason for it to be there

If the type was serializable and the field wasn't static, it would be plausible

(because I've had problems with that before)

[wheat spruce]

what worries me is I would never have spotted the problem until I happened to get the code to clear the static object

[heady iris]

yes, it was quite vexing when I had a similar issue

mysterious bogus object

[wheat spruce]

oh god, this might have explained some issue before where no matter what, something wasnt initialising correctly

[heady iris]

I can't get that exact behavior to happen

    public class Foo
    {
        public List<int> contents;
        
        public Foo()
        {
            contents = new List<int>();
            contents.Add(1);
            contents.Add(2);
            contents.Add(3);
        }
    }

I have a static Foo field on another class, and I check if it's null or not and log its contents

[wheat spruce]

I guess stopping this from happening is the msot important thing

[heady iris]

i also construct an instance in Update if it's null

It's always either null (during the first play session) or valid with three items in the list (during subsequent play sessions)

I guess I should exactly recreate it, by creating a new monobehaviour with the static field on it

[warm rover]

um like make a obj to a navmesh thingy so my agent can walk around on it

sorry for the late reply

[wheat spruce]

Does your code let you click to select anything now?

Surely as long as you can click the inventory slot to select it, the same logic will apply no matter which one is clicked

[heady iris]

Add a NavMeshSurface component to an object in your scene. Ideally, you should have an object called "Level" that has all of the level pieces parented to it

That way, you can switch it to "Current Object Hierarchy" mode. That will keep it from trying to use other random things in your scene

[rugged pond]

I can click on inventory slot to change it but problem is if i have a consumable in my currently active slot and i can use it then i will both use it and change slot while i want to separate it

Triangle-like corners denote active slot

[warm rover]

no im tryna do some other stuff i know how to bake it and stuff

like i need the obj converted to the navmeshsurface

[heady iris]

I have no idea what "converted to the navmeshsurface" means

Are you trying to let an agent walk around on a moving platform, maybe?

Explain what your actual goal is, not your attempted solution

[warm rover]

i have a obj of the navmesh surfaces eg the surfaces it can go on its a mesh. im trying to convert that into a bake kinda the navmeshdata

i need to set the navmeshdata

[heady iris]

Are you trying to update an existing navmesh after moving things around at runtime?

[wheat spruce]

I'm not quite sure, ive got little experience when it comes to inventory type things.
What I would suggest doing is try and get the type of logic you want, but do the testing just with code, not actually using the inventory objects.

Say you had an list with 4 strings, pretend the list is the same as your inventory collection. Press keys 1-4 to set which item is "selected" and then press space to simulate you consuming it to remove it from the list

[warm rover]

my obj i want to be able to turn that into a navmesh everything in that mesh i want to be the walkable surface the obj im sorry if its confusing

[heady iris]

Okay, so you're trying to bake a navmesh while the game is running.

[warm rover]

close trying to convert a obj to the navmesh

[heady iris]

so that you can navigate around a level you generated at runtime, instead of something you built in the editor

[warm rover]

like the surfaces

[wheat spruce]

if you can get that example code behaving exactly how you would in the inventory, you can substitute the list with the collection of items, and then get the code to do the same thing but with the actual game items

[warm rover]

im unable to

[heady iris]

If this is not what you are doing, then I don't understand what you're trying to do. "convert an obj to the navmesh" does not make sense.

[rugged pond]

I see where its going but problem is i use same button (mouse0) to use item and change slot. I can just remove option to change slot by clicking on it and make it by keyboard buttons but if it possible i want to keep both methods

[wheat spruce]

What I mean is clicking on a UI item to set the selection, has a similar principle to "press number 2 to find the second string in a list", its a little more abstract to think about, but its a far simpler context to work in. That simplicity will make it a bit easier to work with, as theres not much that could go wrong with just if keycode(2) { selelect item 2 }. Wheras with clicking the UI element a lot more has a chance for error, making it harder to do the primary goal

[leaden ice]

Can't you just do an if/else

[wheat spruce]

then later on, rather than pressing a key for 2, swap that out with clicking on the second UI item and tell the rest of the code what one was pressed. It will then still do the same "find the second string in the list" but now youve got part of your intended code working in that simpler code

[rugged pond]

I've tried to add if (!change slot) before calling UseItem() but then every time i click somewhere out of inventory it would just not work. Probably bc of broken logic in 'change slot' function so i will invest in it too

[rugged pond]

Will try to recreate it like u said, thanks for tip

[leaden ice]

I mean in the logic for clicking on a slot it should just be like:
if(slot occupied) UseItem()
else ChangeSlot()

[rugged pond]

This would use item at first and if slot is empty it will change it while i want something like if i clicking on non-active slot then this slot become active w/o using item and if i click somewhere out of inventory it just use item from current slot

[bleak olive]

I'm trying to have a functioning multiplayer, but everything I've done to work with this template I'm using has just further screwed it up, I think I might just need to restart and figure it out from scratch

I've never done multiplayer and multiplayer in Godot was always a big no no

[latent latch]

godot eNet is pretty straight forward. I think fishnet docs are pretty weak considering

but fishnet does some have some features like network prediction/extrapolation

[jovial barn]

I'm having a bit of a design problem. I have 3 singletons: wave system, enemy tracker, and waypoint system.

I'm trying to get over my habit of making all my singletons directly dependent on each other but I'm not sure how else to make this structure work. is there a way to make this work with scriptableobjects or some other thing that gets rid of the need for direct dependencies?

I feel like I got a decent start with using events but they still have a one-way dependency that goes in circles, so each system still requires every other system to work

[latent latch]

Is there a reason why EnemyTracker needs to subscribe to the wave system? It's the WaveSystem/GameEventHandler that should be checking out all information needed before spawning your enemies, and subscribing each enemy to the required event handler

[hexed pecan]

Do you have a mesh and you want to use that mesh directly as the navmesh?

[bleak olive]

And those are all things that I need for my game sadly

[inner wasp]

I'm having a bit of trouble drawing a Inventory items icon ontop of the inventory grid slot it's supposed to be drawn on. I'm pretty sure it has to do with the layout not being rebuilt but I'm having trouble getting it to behave the way I want. The issue I'm running into is the position of the InventorySlots don't appear to have been set after the LayoutRebuilder is called. When I step through it I can see that each InventorySlot has the same position.

When an inventory is drawn I have a GridLayout I instantiate a bunch of InventorySlots into,

            // Up here I'm instantiating a bunch of InventorySlot UI elements

            // Force the layout to update so we can rely on the cels being placed accurately.
            LayoutRebuilder.ForceRebuildLayoutImmediate(gridLayout.GetComponent<RectTransform>());

            //After the LayoutRebuilder is called I reference the position of those InventorySlot's to place the ItemIcons properly.
            

Everything is happening within one update, it makes sense that the GridLayout woudln't have time to update.

The reduced snippet I posted is pretty worthless, here's a pastebin link to the offending code.
https://pastebin.com/kvKwqtYv

[vagrant blade]

There's no off topic on this server.

[leaden ice]

you shouldn't need to force any layout updates

just make sure the inventory slot prefabs have the correct anchoring and that you instantiate them with the form of Instantiate that accepts a Transform parent

[inner wasp]

I shouldn't need to force a layout update even if I'm adding a bunch of items to a grid layout and then in the same update trying to reference their position?

[leaden ice]

I guess perhaps if you're trying to reference their positions immediately. What are you using that for?

[dapper pewter]

Anyone know why canceling doesn't work here when rebinding controls? RebindCancelled is never called, it calls RebindComplete when I press Escape.

[inner wasp]

I essentially have two layers to my inventory. A background of "InventorySlots" and a foreground of "ItemIcons" I want drawn ontop of them. I'm using the position of the InventorySlot to decide where to place the ItemIcons on the screen when the UI is drawn.

[leaden ice]

WithCancellingThrough takes an input control path, not an action name.

https://docs.unity3d.com/Packages/com.unity.inputsystem@1.11/api/UnityEngine.InputSystem.InputControlPath.html @dapper pewter

[inner wasp]

In my case I don't know what Inventory is going to be drawn until something like a chest is opened. Since I don't know what inventory is going to be drawn I don't know how large my inventory grid needs to be, I have to draw that all at once.

[leaden ice]

Why not just make the item icons children of the slots?

[inner wasp]

I run into issues with the rendering order. The next slot in line will render overtop of the ItemIcon since it's higher in the rendering order. If you change the rendering order your InventorySlot will be rendered at the end of the GridLayout instead of at it's correct position.

I guess that points to a bigger architectural issue with what I'm doing.

[dapper pewter]

How do I specify one keyboard control and one controller control for cancelling? If I use */{Cancel}, the user cannot rebind a control to B on an Xbox controller

[leaden ice]

I suspect you can call WithCancellingThrough multiple times?

Not sure

[dapper pewter]

According to the docs it can only be called once

[leaden ice]

There's also the Back https://docs.unity3d.com/Packages/com.unity.inputsystem@1.11/api/UnityEngine.InputSystem.CommonUsages.html#UnityEngine_InputSystem_CommonUsages_Back semantic?

might be better than {Cancel}

[dapper pewter]

Still wouldn't allow rebinding B button. I might have to not allow cancelling for now

[leaden ice]

Not allowing canceling is probably what I would do 🤔

because then you can never bind whatever the cancel button is

[dapper pewter]

Or maybe "Menu" control

[leaden ice]

you can always just bind it back to what it was previously

and you can always make a separate "reset" button for each control that sets it to the default

and/or for the controls overall

[inner wasp]

What Praetor is suggesting is pretty common practice.

[dapper pewter]

Looks like "Esc" is not considered to be the keyboard's "Menu" button so */{Menu} does not work

[dapper pewter]

The workaround:

[flint plume]

im running this 3 times at once every few seconds and itll drop to 50fps, how can i optimise it so it doesnt lag or am i fucked

because I want an enemy tracker that keeps track of newly spawned enemies that can come from multiple sources including the wave system, so I need the enemy tracker to subscribe to the wave system among other things

just so there's a master list of all the enemies

[rotund perch]

How do I make properties appear/disappear depending on what Update Type is set to?

after further research this is probably a code-advanced question

it's complicated stuff but pretty cool

[latent latch]

Custom inspector stuff

https://github.com/dbrizov/NaughtyAttributes
Or buy yourself Odin Inspector if you want to free yourself the time of messing with Unity's tools

[rotund perch]

It looks like it's free, what do you mean buy?

[dusk apex]

Naughty attributes is free. Odin is not.

[rotund perch]

Oh

[dusk apex]

There was an or.

[rotund perch]

Yeah the first one was for custom inspector stuff which is a unity thing

Pretty sure at least

[rotund perch]

does showIf work for operations if two objects are the same

[hexed pecan]

You can make a method that checks if those objects are the same and returns a bool, and use that with ShowIf

Or are you asking something else?

[rotund perch]

I'm not sure that would work outside a function

it's for NaughtyAttributes like @latent latch had sent

yknow what this is way too many resources being put into a script I'll likely use like 5 times

[knotty sun]

Not the point, it's knowledge useful for your future self

[rotund perch]

yeah...

[compact spire]

If I have a game with an in-game editor, like stormworks/from the depths/Kerbal space program ect... When I'm putting together the craft, there is a lot more editor specific data (connection points, ui elements ect) that aren't part of the "in game" objects. It doesn't make sense to include them as that's adding quite a bit of unnecessary overhead per object, but it also doesn't make a whole lot of sense for them to be completely seperate as the editor needs a lot of the game data. Would it work to make the editor object a wrapper around the game object? Or use something like a scriptable object to store the data for both? I don't think sharing a common interface or using partials/abstracts is the answer... but I am not certain.

[rotund perch]

I basically have a list of values for each object that are shown to the in-game editor and then the object can read for itself what those values are and do what it wants with them

Like this

got a bunch of other unnecessary logic in there too

That solution seems a bit line heavy

[rotund perch]

I've been brainstorming other ideas

Maybe having a class that contains all of the other ones so I can just have one array of all of those

using enums or something

but that has the downside of likely making my levels bigger

[compact spire]

I think scriptableObjects might be the key, but it's been a while since I've tinkered with those

[dense yoke]

When it comes to shooting a gun at another player what is better to use as an example a player shoots an arrow at another player? My question is what is better to start or upgrade so that the arrow hits the target which would be the player?

[knotty sun]

you are asking the wrong question. You need to think if you want your projectile to be controlled by physics or not

[dense yoke]

ok

Yes and I don't want to make projectiles that respect physics and others that don't.

[knotty sun]

that statement makes no sense and does not answer the question

[dense yoke]

I don't know how to develop the question in English

[knotty sun]

you asked about shooting an arrow, there are 3 ways to do this

1. using physics
2. not using physics
3. using animation
   which do you want?

[dense yoke]

one

[knotty sun]

so you need an example of firing a projectile using rigidbody physics

what the projectile is is completely irrelevant

[dense yoke]

why irrelevant?

[compact spire]

Once you have a working example of a projectile using physics, you can apply it to arrows or anything else that you want to be affected by physics.

[dapper pewter]

The one problem with this is that each rebinding button is either for keyboard or gamepad and won't allow inputs for the other control type. That's fine, but it also won't accept cancel inputs for the other control type, which would fail Steam full controller support requirements as the player could get into a situation where they are forced to use a keyboard. So I think I will need to add a cancel check in Update

[loud heath]

I keep on getting a NullReferenceException for line 19 in my PlayerHealthBarUI.cs file. This is the line of code: "playerHealthManager.OnHealthChanged += HealthManager_OnHealthChanged; I'm confused and could someone try helping? Thank you in advance

[dapper pewter]

Presumably playerHealthManager is null, is that component definitely in an active parent object?

[leaden ice]

NREs are always the same

You're dereferencing a null reference

[heady iris]

if (input != 100)
    throw new NullReferenceException();

sneaking this into my library somewhere

[leaden ice]

Boo

Easy for people who read stack traces though

[heady iris]

I bet you can construct a completely fake stack trace

[short flare]

pls help. Whenever i make a new project, this shows up and i cannot playtest.

[leaden ice]

I would simply uninstall the Version Control package

Assuming you're not using it

[short flare]

how?

[leaden ice]

From the package manager of course

[short flare]

oh ok thanks

[short flare]

its still there

is there any other cuases?

it said sometghing about a memory leak

[leaden ice]

What packages do you have installed

Show the list

[leaden ice]

Show in the package manager

[short flare]

oh

[leaden ice]

Try deleting your library folder

[short flare]

what does that do?

[short flare]

where

[leaden ice]

In the project folder

It gets rid of stale crap

[short flare]

i dont see a project folder

[cosmic rain]

They mean your project folder. Surely you have it if you have a project.

[short flare]

yeah i have a project folder but i dont see library'

[leaden ice]

In windows explorer or finder

[short flare]

ok, how do i do that

[cosmic rain]

Take a screenshot

[short flare]

this is it right?

[cosmic rain]

Not in unity...

[short flare]

in files??

[cosmic rain]

Yes. In file explorer

And anyways, the folder you selected is "packages". No where near "project folder".

Well, actually near. It's a child folder of the project folder.

[short flare]

so how do i get to library? i am searching for the game

[cosmic rain]

Do you know where your project folder is located? (You should know that, as you specified the path when creating it)

If you don't know, look in the hub. It tells you where.

That is the project folder.
Open it in windows file explorer or whatever your os has. And look at the contents.

[warm rover]

yes

[wide totem]

Hello, I wanted some advice on a pathfinding system i was going to build for an enemy that can climb walls.
Currently, my idea is to have the enemy do the following steps
1 - get the general direction of goal (either front or back)
2 - shoot a raycast in that direction until it collides with a ground object
3 - shoot a raycast upwards/downwards
4 - (where one of my problem is) somehow detect where the 'wall' ends
5 - repeat 2-4

oops didnt mean to hit enter

[wide totem]

my other problem is knowing when to go forwards when the targets position is behind but not accesable

ive triedto search this but havent found anything relating to climbing enemies

[dusk apex]

How do you know it's stopping?

[visual fjord]

Thanks debug.log()

[dusk apex]

Are you manually stopping the coroutine?

Maybe you should explain what's happening and what's not.

ie stop spawn enemy shouldn't have been called but it is etc

[visual fjord]

Well, the coroutine 1 spawn enemies, when shoot an event, the function of this event stop coroutine 1

[scenic pewter]

okay im making this really basic flappy bird game, but im coming across the weirdest thing, im coding a script for the camera to follow the player, its overcomplicated because im trying to fix this bug, where when the game starts, the player just disappears, if i comment the script, the player no longer disappears, why does this happen?

like ive never had this happen

[somber nacelle]

your camera is too close to the player for it to render. you need to put the camera at or below -10 on the Z axis and your player and other objects should be at or above 0. this is the typical pattern used to ensure that issue never happens, though realistically you only need it at least as far away as the camera's near clipping plane

[somber nacelle]

your code sets it to 0

[scenic pewter]

ohh right

im dumb thanks

[somber nacelle]

but also for flappy bird, you typically wouldn't need to move the bird and camera along the x axis. the pipes would be moving along the x axis

[scenic pewter]

right, thanks

@wheat spruce I did end up checking out Stateless. After fighting with it to get it installed (I tried as a nuget package... that didn't work). I've gotten used to it and I think it's going to save me a lot of work.

[warm badger]

how do i remove or destroy the combined mesh that was created by StaticBatchingUtility.Combine? without using resource.unloadunused...() @cosmic rain can you help me regarding this?

[cunning lion]

Hi! I have started to use localization package and dont understand what is the best way to get any information from it? Like its neccessary to wait until LocalizationSettings are initialized, before it starts return any data, so what optio do I have to wait for initialization complete?

Option 1 I see is, (but it doesnt looks like 100% guarantee to fully initialized localization before usage)
IEnumerator Start() {
yield return LocalizationSettings.InitializationOperation;
//next code here in hopes that all methods of this class will be called only after 'Start' execution is finished
}

Option 2 I see is call wait coroutine for each method of this class, but it looks kinda weird

IEnumerator WaitForLocaleInitializationCoroutine(Action action) {
isInitialized = false;
yield return LocalizationSettings.InitializationOperation;
isInitialized = true;
action.Invoke();
}

public void ExecuteAfterInitialization(Action action) {
    StartCoroutine(WaitForLocaleInitializationCoroutine(action));
}

Do you have any ideas how to make it possible call methods of this class in another classes dont thinking about is 'LocalizationSetttings' initialized or not?

[wheat spruce]

Glad to hear! It's pretty strange to work with at first, but it did end up being a really nice way to design state machines

It's mermaid graph feature also turned out to be a really helpful way to see how the machine is set up. Especially to help catch situations where the machine wasn't set up how I expected

[warm rover]

Is there anyway to generate links in runtime

nothing works

build settings dont

[soft shard]

Why might you need build settings to generate links? Links for what specifically? Like a hyperlink that takes you out of the game and to a browser webpage? Or a different kind of "link"?

[warm rover]

offmeshlinks for navmesh

[soft shard]

Ah, sadly I am not familiar enough with NavMesh API to help there - build settings is usually used for choosing the scenes that will be built with a playable version of your game, I assume you meant the nav mesh bake settings which I believe you can do at runtime, though im not sure if that applies for links as well - have you already checked the docs for info about it?

[warm rover]

ive checked everything including the dll source codes and stuff its ashame i might have to make my own generator

[soft shard]

Hmm, that would give you more control over features and optimization, though it could also be time consuming to build, if you already looked through the github source code, maybe you can try looking for potential solutions on the asset store or other non-official git projects, or possibly try asking again with more details on your research and goals later when more devs might be awake

[warm rover]

yeah thanks its been like 5 days ive been trying to figure this out ive gone thru like 200 github repos about navmesh and there is no hope

[soft shard]

What happens when you try to create a offmeshlink component on a empty object by code?

[wheat spruce]

I'm sorting out my code for the whole terrain system I'm writing. I have a very bad habit of taking a class that should only ever be very simple, then overcomplicating it by adding far too much in.
For instance in my Grid, I ended up adding a lot of logic and functions to it, but all the Grid actually needs is to be very minimal like:

public class Grid
{
public const int CellSize = 0;
public int Width { get; set; }
public int Height { get; set; }
}```

What I'm wondering is what the smart way to build on top of my Grid, without actually going in and messing its simple definition.

Its a side of C#/OOP that I've not played around with all that much

My only real idea is that I want to use the Grid as the base for anything that is based around the grid such as public class TileMap : Grid

[warm rover]

nothing

[wheat spruce]

Thats good when I want to make a whole class do something based on a Grid. But its not actually doing anything special with the Grid class itself.

Part of what I had in my Grid before was for it to use my Rectangle class

public Grid(Rectangle rectangle){
  GridWidth = Mathf.RoundToInt(rectangle.Width + Padding);
  GridHeight = Mathf.RoundToInt(rectangle.Height + Padding);
}
public void SetSizeFromRect(Rectangle rectangle){
  GridWidth = Mathf.RoundToInt(rectangle.Width + Padding);
  GridHeight = Mathf.RoundToInt(rectangle.Height + Padding);
}```

I dont know if it could be possible to do it, but could I do something as if my Grid was a partial class (not that partial is actually what I need)

public partial class Grid{
int Width, Height;
{

public partial class Grid.viaRectangle{
rectangle MyShape;
SetSizeFromRect()
{```Like I could leave the Grid itself unchanged, but have some secondary version that lets me build onto the base

🤔 have I somehow explained dependency injection? its something ive heard of but havent ever used

[mossy snow]

I would avoid clever code. Your example so far seems like something reasonable for Grid to have

[vestal arch]

you sure you want RoundToInt there? trunc/floor might make more sense than rounding there

[wheat spruce]

it starts out that way, but before I know it, I "screw up the simple"

[vestal arch]

rounding is more for approximation or for display, not for literal float to int conversion

[wheat spruce]

I dont, no. Thats why I'm remaking the Grid class

[mossy snow]

if Grid starts having things that don't apply to all grids, you probably want composition instead. Maybe things need a grid, instead of things BEING grids

[vestal arch]

uhh i don't see how changing a conversion method leads to remaking an entire class but ok

[wheat spruce]

I just mean that Grid should only ever be extremely basic

nothing fancy is needed for it, especially having grid depend on other classes even when Grid will commonly be used with those

"oh I need a rectangle to set grid dimensions, so let me make Grid have to contain a rectangle"

[vestal arch]

i mean this is a thing https://docs.unity3d.com/6000.0/Documentation/ScriptReference/RectInt.html

[wheat spruce]

I know Unity has a class for it, but I'd rather have my own shape implemetation

[mossy snow]

if your Grid consists of what you have listed so far (parameters + constructor and a function that just rounds some ints), I'd say it's arguing for its own deletion instead because it doesn't really do anything particularly useful worth existing over

[vestal arch]

why?

[wheat spruce]

main reason, the classes themselves are extremely basic so its not much extra work to create them

also it doesnt lock my code to only work explicitly with the unity API

[vestal arch]

that's not really a reason to remake them

[vestal arch]

so you're intending this to be standalone, unattached to unity?

[wheat spruce]

thats a perfeclty valid reason to make them

[vestal arch]

it isn't even related to remaking them

"it's not hard" isn't a reason to make them, it's just a lack of a reason against making them lol

making a paper airplane isn't hard, but that's not a reason to make them
maybe you wanted to, now that's a reason

[wheat spruce]

I guess deep down, its a preference thing

[vestal arch]

i suppose this as well?

[wheat spruce]

that is a factor, but its not like I'm making the entirety of my code be able to be standalone from unity

I am using Unity afterall

ive always felt more comfortable working in a way where my project wont be fused completely with something

[vestal arch]

i mean if you're only going to be using it for unity, i'd (softly) recommend using unity's stuff so it can integrate with other unity stuff without having to convert all the time

[wheat spruce]

I think Rectangles are the only things Unity has that I probably could use without implementing again

[vestal arch]

if you think you would maybe want to extract it and use it for some non-unity-related case, or perhaps port it to a different context, then yeah that'd be a solid reason to make your own stuff

but having stuff very similar to unity's but just slightly different might cause you some pain in the future, like confusing your own rect with unity's rect, for example
like, in the context of your grid, your rect might be integral, but unity's Rect is floating-point, while RectInt is integral

also if you get used to unity's api, muscle memory might make it inconvenient to use your own api, and vice versa

to be clear; im not exactly trying to convince you to use unity's stuff, im just mentioning this as stuff to keep in mind if you do decide to make your own api

[wheat spruce]

I'm pretty careful these days when it comes to making sure I dont use the wrong class, its caused me problems before where I hadnt realised why I couldnt call certain functions that I knew were in my class

[vestal arch]

something you might not be able to foresee is how your future self will interact with those systems, if your future self will have that same mindset

never get too confident with this stuff lol, it'll come crashing down...
-# definitely not speaking from experience...

if you're making anything long-term, make it so a stranger would be ok with it, since that's effectively what your future self is to your current self

[cold parrot]

A grid is a data structure or indexer that is based on discrete increments, therefore you would base it on integers and cell counts and make float dimensions completely abstract to it. Therefore using unity’s float based shape stuff makes no sense (other than in a public API for convenience) and custom everything is the easiest way to make it simple.

[wheat spruce]

other thing to note is I'll have a number of different geometry objects, because if I have PolyShape CircleShape LineShape HexagonShape BoxShape etc, all with their own Polygon, Circle, Line, Hexagon geometry struct, but only BoxShape uses Unity.Rectangle

[vestal arch]

hmm that inconsistency could be a problem

[wheat spruce]

I'm using my Grid class purely for the the base properties to set up the dimensions and how large cells are. I have a couple different classes that both use the same Grid but have different uses

if I change the grid size, all I have to do is update the base Grid, and my different tilemaps will both be the same after

its the derived classes that have the actual stuff that gets placed inside the grid

[warm rover]

https://github.com/orangeagain/unity-navgen/tree/example i just found this it holy moly 😭 only took 5 days

[cold parrot]

i was just giving you an example for a reason why you would build your own stuff with nobody questioning that decision.

[wheat spruce]

aah, got ya

[cold parrot]

you do whatever feels right to you, else you you won't know when you go off track. You can always do it different next time. Following advice that you don't feel yet leads to more problems than something that is objectively "not ideal" but well understood by you. All code that was ever written is "bad" by some metric, and those who think their code is great are just naive.

[wheat spruce]

also with the dependency injection thing, I sort of understand the idea of it. Could it be used for something like this?

class RectangleGrid
{
public RectangleGrid(Rectangle) : Grid()
}```As in RectangleGrid itself behaves and is used exactly like Grid. I could use a Grid or RectangleGrid to both make a TileMap, but now my RectangleGrid is specially intended to be used with a Rectangle

I just really want to avoid adding loads of extra stuff into the main Grid class, its whats got me into the mess I have where very simple classes end up being impossible to manage if I get carried away

[wheat spruce]

  internal class Grid
  {
    // dimensions of cell
    public const int CellSize = 1;

    // dimensions of grid
    public int Width => _rect?.WidthRound ?? 1;
    public int Height => _rect?.HeightRound ?? 1;

    private Rectangle? _rect;
  }```I suppose this could work, rectangle now is an optional way for the grid to automatically set the dimensions from it, defaulting to a size of 1 when its not set

[marsh geode]

hey fellas, I'm using Newtonsoft.Json along with my unity project since JsonUtility seems limited, but when I serialize something like a Vector2 it adds useless information like

          "x": -0.97618705,
          "y": -0.216930449,
          "magnitude": 1.0,
          "sqrMagnitude": 1.0
        },```

is there any way to exclude this?

[wheat spruce]

whats useless about this data that says what the Vector2 contains?

because thats what a Vector2 is

[sage latch]

I believe you have to make your own vector2 type :/

or actually I think you could use a custom https://www.newtonsoft.com/json/help/html/T_Newtonsoft_Json_JsonConverter.htm

[wheat spruce]

if its only the position you want, just use a tuple (float x, float y) and serialize that and then reconstruct the vector2 when you deserialise

at least that is if json supports tuples

if not, just two different floats

[pulsar ocean]

Hey,
I have a Coroutine where I want to set the Material of an Object to a glow Material for a few seconds. The code I have does work fine during testing in the editor bit it somehow won't change the Material during runtime. I've tested if it calls the method and it does, every part of it gets called (at least the parts I could check: the emission color, the waitforseconds, etc.). Can someone help me? What am I doing wrong?

IEnumerator Glow()
        {
            Material glowMaterial = new Material(originalMaterial);
            glowMaterial.EnableKeyword("_EMISSION");
            glowMaterial.SetColor("_EmissionColor", glowColor * glowIntensity);
            rend.material = glowMaterial;

            yield return new WaitForSeconds(glowTime);
            
            rend.material = originalMaterial;
        }

[surreal thorn]

Hello, did anyone have this issue?

The project was working fine on another computer a year ago, but when i imported it onto a new system just now, it gives me this.

[thin aurora]

No he doesn't

@marsh geode Use this package 👇

For some reason the Unity devs are unable to add proper support for proper serializers and therefore their bad conventions interfere with serializers like Newtonsoft and STJ. The issue is that JsonUtility by default serializes fields but Newtonsoft and other serializers use properties. In this case Unity has properties that should not be included but rather ignored, but this is not done by default.

This package basically fixes all the types. I'm pretty sure you just need to add it and it will work out of the box

[thin aurora]

Try deleting your Library folder and have Unity regenerate it

If it worked before, perhaps it somehow left something out

Otherwise this package is just broken

[surreal thorn]

I already tried it

[surreal thorn]

How so? can I fix it in any way?

[thin aurora]

If you didn't edit it then it's simply not compiling due to a missing namespace

Hard to say because I never used it

[surreal thorn]

It's weird but the Visual Studio doesn't highlight any problems when I open up these scripts

[thin aurora]

This code looks fine, your build likely broke another way and this is simply an after effect of it

I suggest you check for errors

[thin aurora]

Did you try recompiling?

Maybe you have unsaved files?

[marsh geode]

sickkk thanks man!

[thin aurora]

It is possible you have unsaved files that do end up fixing the issue, but these won't be included during compilation

[pulsar ocean]

I don't see any errors in my log file though

[thin aurora]

Hard to say from the code you supplied

I suggest you check if the objects exist and/or if the objects it tries to set the material on match

Specifically whatever rend is

[zenith zealot]

silly question, can you do a bar fill with sprites instead of UI elements? every tutorial im finding is about the UI

I have an arrow for aiming and I want it to fill and unfill to show the power behind the shot. I feel this would work better as not part of the UI

[pulsar ocean]

I noticed that it works if I put another object in the scene with the urp lit shader (the same shader my other material uses) that has emission enabled. But what if I don't want that? I don't want to include another object with emission enabled into the scene just for this material to be able to use emission. (and rend is the Renderer)

[zenith zealot]

in fact, using a UI would not be feasible at all due to the nature of this

[zenith zealot]

actually, could a sprite mask work i wonder

[spare dome]

don't crosspost

[balmy plume]

sorry

[young tapir]

If I have two non-kinematic rigidbodies, each with a collider and custom component listening for OnCollisionEnter, and they collide. Will both OnCollisionEnter methods create a separate Collision or do they share one between them?

I'm mainly asking because I'm trying to make my collision system a little more intuitive but I can't think of a better way to stop both scripts play a sound on collision other than adding a tiny delay between when they can play.

[leaden ice]

OnTriggerEnter never creates a Collision

they simply call OnTriggerEnter

with teh Collider as a parameter

it will run on both objects

[heady iris]

You can compare your instance ID to the other side's instance ID to prevent two sounds from playing at once

(check the ID of your game object vs. that of the other game object)

[young tapir]

I feel stupid

I meant to say CollisionEnter, not trigger

[heady iris]

Keep in mind that OnTriggerEnter will run on the object with the Rigidbody on it

[leaden ice]

yes - simple trick:

if (gameObject.GetInstanceID() < other.gameObject.GetInstanceID())```

[heady iris]

ah, okay, so you do get a colliison

[heady iris]

That makes it easier to do this!

compare the instance IDs of the rigidbodies

[leaden ice]

You will not get OnCollisionEnter for two kinematic Rigidbodies ever

[heady iris]

that prevents any ambiguity

non-kinematic

[leaden ice]

you need at least one dynamic body

oh

I misread

[heady iris]

not non-non-kinematic

😉

[leaden ice]

anyway yeah, the whole instance id thing is relevant

[heady iris]

Instance IDs are unpredictable, but they are very useful for creating an ordering between objects!

[young tapir]

That may be useful, but do they not both have a separate collision?

[heady iris]

I think that depends on this setting.

If this is turned on, every single OnCollision* method is passed the same Collision instance

the values just get swapped out

[young tapir]

Ah so that would hopefully ensure the "hit" and "source" colliders are shared between both colliders?

[heady iris]

I don't follow.

I'm just talking about the actual Collision object

[heady iris]

I'm not sure what "have a separate collision" would mean

[young tapir]

If both RBs have the script and they collide, my thinking is that each will have their own other.collider, so both will technically be the other collider

I find it kind of tricky to put into words

[heady iris]

If you have a component on both objects that implements the OnCollisionEnter method, the method will get called twice -- once on each instance of the component

The collision object (which you should not call "other" -- that sounds like what you'd name the Collider parameter for OnTriggerEnter) will contain information about the collision

if we call these two objects "A" and "B", then A's OnCollisionEnter callback will point to B's rigdibody and collider

and vice-versa

[young tapir]

Yeah.. I think that's where my problem lies

I can compare A's collider to B, but it'd also be compared in B, to A

[heady iris]

What is the actual problem?

[zenith zealot]

ayyy a spriate mask worked

[balmy plume]

it does create two seperate instance of the collision one for each object

[leaden ice]

I don't really think their question was actually about the Collision instances. They were really asking if OCE gets called once or twice

[balmy plume]

if both gameobjects have the method then both of them will call it

[young tapir]

I'm curious if they create two Collision instances when they collide, I know both will call OnCollisionEnter

But if they do, that's annoying

[leaden ice]

#archived-code-general message

[balmy plume]

yes the do create two separate collision instance as much as i know

[heady iris]

I don't understand why this would matter to you at all

This would only matter if you were, say, putting the Collision objects into a hash set

[young tapir]

When both collide, they'll both play an audio clip and effect. I reaaaally don't want both to play a separate effect, I want it to become a combined collision that plays an effect based on this ^^

[heady iris]

Okay, but that doesn't answer my question!

You keep saying "two Collision instances"

This makes it sound lke you're asking if the two invocations of OnCollisionEnter get passed the same object or a different object

[leaden ice]

Again your question is actually about whether OnCollisionEnter runs once or twice, not about the Collision object instances. And it's already been answered 3 times over.

[heady iris]

I think you're asking about whether you get two callbacks, yes

[young tapir]

I am fully aware OnCollisionEnter is called twice, as I have already said 🙃

I've already explained my original question to the best of my ability, but I was curious whether they'll produce two different Collisions, or one between the two colliders that hit. Which I got an answer to from Raziel

As far as I know or understand, I've answered your questions as best I can.

[heady iris]

The behavior depends on this Physics setting.

[young tapir]

Which I am, as of current, looking into

[leaden ice]

Why does it matter? How would that help solve your problem?

The Instance ID check is the solution to your problem.

[young tapir]

A small screenshot isn't exactly helpful and Im slightly concerned I'll get my head bitten off if I ask where it is 😛

[heady iris]

Project Settings > Physics

I still do not understand how this is relevant, though

[young tapir]

I explained here ^^

[heady iris]

Your actual problem is "how do I only play one sound when a collision happens?"

Whether or not the Collision object is re-used is irrelevant

[leaden ice]

Yes we understand this, but the collider instance issue doesn't provide a solution to it either way.

[balmy plume]

wait so the instance id will be the same if this setting is turned on?

[heady iris]

No.

Collision is not a unity object.

It does not have an instance ID.

[leaden ice]

Collision doesn't have an InstanceID either way.

[heady iris]

In fact, in both cases, it wouldn't give you enough information to solve the problem

[mossy shard]

does anybody know why i get these random errors when i actually do nothing?

they just like sometimes decide to appear

[balmy plume]

then what is the actual difference?

[leaden ice]

read the full stack trace

[young tapir]

I didn't come with a direct problem, but yes that is something I was trying to fix.

All I was curious about was how the collisions are produced, and what would stop them from producing two, which you have since answered. ^^
Really no need to be hostile especially considering you've helped a ton

[leaden ice]

Whether the Collision object gets reused or not. Reuse means less garbage created, but it also means you might introduce a bug by storing the object somewhere and assuming it won't be overwritten

[heady iris]

I'm not being "hostile". I'm just trying to get to the point.

[balmy plume]

oh okay got it

[heady iris]

You're clearly getting XY-problem'd here and I'm trying to steer you back to your original problem

[mossy shard]

i do not know how the screen position is out of view when i don't move, and i only change the code for something like player health

[young tapir]

Hm. Finishing sentences with ! to indicate you're frustrated at me for a reason I don't understand tends to come off slightly hostile

[leaden ice]

There's no hostility, we're just trying to figure out how you intend on the reuse or not of the Collision object as a solution to your original problem.

[leaden ice]

To read the full stack trace you click on the error and read the full expanded message at the bottom of the console window

[young tapir]

Yes. That was, as I've said, already answered by you. Thank you for the help 😁

Maybe we should all be more mindful of how others might perceive a potentially negative comment on a text app, where you can't properly gauge someone's intent 😄

[mossy shard]

On everybody's soul, how does it help me if it ,,traces" me to a class from the unity library 🙏🏻

[leaden ice]

it helps you because it shows us the source of the error. Can you show the full stack trace?

If indeed it's coming entirely from Unity stuff, it rules out a problem in your code, for the most part

Deductive reasoning.

[zenith zealot]

lmao

yes thats pretty much what i did

tho i used scale in my code to basically scale the size of it in relation to the power of the shot, filling an amount of the aiming arrow proportional to the power of the shot

[vague surge]

Anyone implemented Meta AvatarSDK in Unity6? i feel like the doc is outdated but there's no incompatibility warning from meta (i've noticed prefab are missing, Oculus/Avatar2 folder doesn't have anything useful inside)

[zenith zealot]

[scarlet plank]

Does anyone know how i could create random room generation for a backrooms game

[mossy shard]

in theory is it better to put a bunch of if's and call them async in the update or only have a while

idk how unity handles loops in the update, so i ask

[latent latch]

update itself is just one large loop

[vestal arch]

unity doesn't handle loops in update, the runtime does
unity just says when to call update

[latent latch]

I wouldn't really use while loops in update unless you know what you're doing. Just stick to for loops and add your constraints onto that

[balmy plume]

whats wrong with while loops?

[latent latch]

coroutines are an exception though

[latent latch]

easy enough to get stuck in an infinite loop if you don't add any condition

[balmy plume]

that could happen to for loops too tho

[latent latch]

obviously you can fall into that problem with for loops, but you're still usually adding some constraint onto those so less likely to fall into that problem

[mossy shard]

so all the unity code can stop in an infinte loop?

[mossy shard]

ye, i switched my while to a bunch of if's , but i don't like that everything stops until the while ends

[balmy plume]

just check ur logic so u dont get an infinite loop

[mossy shard]

plus it takes a while to calculate

[heady iris]

If your Update method never returns, the game will freeze.

Unity executes one thing at a time.

It's not running a bunch of methods simultaneously (at least, not generally)

Some things are run in parallel, of course

but all of those MonoBehaviour messages (Start, Awake, Update, OnCollisionEnter, ...) sure ain't

[wheat spruce]

internal abstract class Grid
{
  public static Point[] PointMap;

  public T[] InitializeArray<T>(Func<int, int, T> factory)
  {
    ...
  }

  public Grid()
  {
    if(PointMap == null)
    {
      PointMap = InitializeArray((x, y) => new Point(x, y));
    }
  }
}```Got a similar thing where the static property isnt being cleared when the game is stopped, but I cant do `Grid.PointMap = null` because Grid is abstract

not too sure why I cant even access it from my tilemap class, which is class TileMap : Grid

[heady iris]

don't access it from an instance

you have to access it from the type name itself

[wheat spruce]

ooooohhhh

of course

[heady iris]

note that this isn't giving a separate PointMap field to every child of Grid

there is one and only one PointMap field

[wheat spruce]

yeah, shared between both

[mossy shard]

would it be possible to multi-thread?

[heady iris]

Not if you want to be able to touch Unity objects

That must happen from the main thread

the Jobs system exists to let you do work on other threads (including stuff like mass-updating Transforms)

but you can't just flip a switch and run eight Update methods simultaneously

[wheat spruce]

what is it youre doing to make it so slow?

[mossy shard]

me?

[wheat spruce]

yeah, you said it was taking a while to run

could be a case that you accidentally wrote the loop in a way that it's doing extra work, making it slow to execute

[mossy shard]

i have cooked the most monstrous enemy AI known to mankind🗣️ 🔥

[heady iris]

If you can gather all of the information you need all at once and then never touch a Unity object again, you can pretty easily do that in a Job

[mossy shard]

idk what you mean by an unity object

[heady iris]

anything that's derived from UnityEngine.Object

game objects, components, etc.

You're not allowed to interact with the Unity API from anywhere but the main thread most of the time

So, if you can make a big list of numbers and then go do a bunch of thinking about those numbers, you can do that in a Job (and run it on another thread)

[mossy shard]

oki

all i needed

thank u

[heady iris]

If you're doing a ton of number crunching, you can also look at Burst

It can compile a subset of C# to native code, which is double-plus fast

I use this for code that does gradient descent, for example

I run it in a burst-compiled job on another thread

...well, I could, but I currently just run it on the main thread

[balmy plume]

i thought burst was very unforgiving about memory leaks?

[heady iris]

There are rules about how long your allocations can live, I suppose

e.g. a Temp allocation can't be used in a job at all, and a TempJob allocation is supposed to live just four frames

But that's a Job thing

maybe you're thinking of things like out-of-bounds memory access?

Burst has safety checks in the editor, but I believe those aren't included in the built game

(since those checks can have a significant performance impact)

[balmy plume]

idk about it much as i havent used it a lot but one of the few instance that i did it gave tons of warnings that i had to resolve before i could get my code running

[rugged pond]

Hello, can someone help me to solve a problem with player position. Every time i drop item from my inventory my player moved a bit and by commenting code i found problem in this line GameObject newItem = Instantiate(itemPrefab, spawnPosition, Quaternion.identity); but it should not change player position and only use it to spawn object. I've tried to remove offset and then player moved to the right side every time

[SerializeField] private GameObject player;

---

public void DropItem()
{
    Debug.Log($"{itemSO}, {quantity}, {player.transform.position}");
    dropManager.CreateItem(itemSO, quantity, player.transform.position);
    Debug.Log("Item was dropped");
    EmptySlot();
    Debug.Log("Slot was cleared");
}

---

public void CreateItem(ItemSO item, int amount, Vector3 position)
{
    Vector3 randomOffset = new Vector3(
    UnityEngine.Random.Range
        (-1f, 1f),
        0f,
        0f
    );

    Vector3 spawnPosition = position + randomOffset;

    GameObject newItem = Instantiate(itemPrefab, spawnPosition, Quaternion.identity);

    Item itemComponent = newItem.GetComponent<Item>();
    itemComponent.ExtractSOData(item, amount);
}

[heady iris]

nothing in here moves the player; I presume the item is overlapping the player and pushing them

[balmy plume]

if the item has a collider and its spawning in player's tranform.postion then it deflects the player

this is a general problem that occurs a lot just spawn the prefap at an offset

[rugged pond]

I've tried to use DropItem w/o any items in active slot and even in this case player moved

Oh, i guess i found problem. Game just create empty objects and move player

[heady iris]

well, does it still spawn something?

that's all that matters

[balmy plume]

ya cuzz it still passes and spawns an empty object

[scarlet plank]

is there any way that i can save whats i have in play mode to my editor

Nvm

[balmy plume]

I dont think that is possible without adding a script for it, its better to just remember the changes and change them in the editor manually

[latent latch]

You can prefab stuff and it will save its state

[balmy plume]

i am sure there are some extensions for that

[scarlet plank]

I just copied and pasted the assets lol

Im making a backrooms game it was for wall generation

But i can just copy paste the walls

Like they were

[heady iris]

you can write code that runs in edit mode

you have to be more careful in there, of course -- such as correctly registering new objects with the undo system

[grizzled ferry]

Does anyone know why my MultiColumnListView doesn't display the NoneElement properly?

It's just a label

[heady iris]

I forget the name, but there's an "inspect" view (a lot like in a browser's dev tools) to look at the UIToolkit layout

That might help

[grizzled ferry]

Does it have to do with the way I'm making it? I'm just instantiating a Visual Tree that contains the message label

table.makeNoneElement = noPlayerPrefsMsg.Instantiate;```

[heady iris]

It kind of looks like the label is displaying in the Value column, instead of taking up the entire row

[grizzled ferry]

if I resize the value column it doesnt move though

[rigid island]

more of a #🧰┃ui-toolkit question probably

[grizzled ferry]

I found the label... It seems to be outside the list

[grizzled ferry]

oh yeah my bad

[balmy plume]

Is there a way to make the camera less choppy ?
So my camera is attached to a parent CameraHolder, and Player object has an empty tranform cameraPostion, and the camera holder's postion is being updated to the cameraPostion's position, player has rigidbody and is set to Interpolate, and still while moving the camera is kinda choppy, is there a better way to implement this?

[soft escarp]

how do i import cinemachine package to my code?

[soft escarp]

cinemachine

i tried everything and settled it with cm

[balmy plume]

could u link the doc for it?

[soft escarp]

#🎥┃cinemachine

idk if there is a doc for it but its a unity package and its pretty easy to set up

[balmy plume]

okay this should solve the problem ty!

[balmy plume]

are u asking this or were u telling me?

[soft escarp]

asking

[balmy plume]

package manager

[soft escarp]

i meant something like using Cinemachine; or smth

i have the camera imported for a long time

[balmy plume]

oh i have no idea i have never used this lol

[steady bobcat]

if using asm defs, add a reference to the cine machine ones

[spare dome]

https://docs.unity3d.com/Packages/com.unity.cinemachine@2.3/manual/index.html
https://docs.unity3d.com/Manual/com.unity.cinemachine.html

[balmy plume]

ty

[spare dome]

You don't need to use cinemachine but it is recommended by many, if you would want to fix your current issue we would need to see your code

I have not used it in a long time

[soft escarp]

uhh, i dont understand anything you said rn
what assembly definitions?

[steady bobcat]

https://docs.unity3d.com/6000.0/Documentation/Manual/assembly-definitions-creating.html

if you use these you have to add references to others to access the code in them (e.g. cinemachine, addressables, unity iap)

[balmy plume]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;


public class CameraRotation : MonoBehaviour
{
    private Vector2 turn;
    private bool isEnabled;
    [SerializeField] private float mouseSens;
    public Transform oreientation;
    private void Awake() {
        isEnabled=false;
    }

    private void Update() {     
        if(Input.GetKeyDown(KeyCode.LeftControl)&&!isEnabled){
            isEnabled=true;
            Cursor.visible=false;
            Cursor.lockState=CursorLockMode.Locked;
        }
        else if(Input.GetKeyDown(KeyCode.LeftControl)&&isEnabled){
            isEnabled=false;
            Cursor.lockState=CursorLockMode.None;
            Cursor.visible=true;
        }
        if(isEnabled)
            enableRotation();
    }

    private void enableRotation(){
        turn.x+=Input.GetAxis("Mouse X")*mouseSens;
        turn.y+=Input.GetAxis("Mouse Y")*mouseSens;
        turn.y=Mathf.Clamp(turn.y,-90f,90);
        transform.rotation=Quaternion.Euler(-turn.y,turn.x,0);
        oreientation.rotation=Quaternion.Euler(0,turn.x,0);
    }
}

for the camera postition its just

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraPosition : MonoBehaviour
{
    public Transform cameraPosition;

    private void Update() {
        transform.position=cameraPosition.position;
    }
}

[spare dome]

does it stutter when moving and rotating the camera? If so use lateupdate for the enablerotation function to see if that fixes it

[balmy plume]

it doesnt stutter normally only when i move does it stutter

[spare dome]

I would try using lateupdate, other than that I do not see any issues with your code

[balmy plume]

ya i am trying lateupdate to see if that fixes it

[balmy plume]

i tried it but there doesnt seem to be any change

ig i have to look up doc for cinemachine afterall

[soft escarp]

also try enabling vsync, i didnt try this back when i tried to make stutterless camera

and even when cm stutters try vsync

[balmy plume]

okay i will try that ty

[balmy plume]

its better definitely but not exactly fixed so i am gonna try the cinemachine anyway ... also cuz the input system is kinda sick

[steady bobcat]

Cinemachine will make it work as it smoothes out the following and focusing it does. You can do the same manually

[heady iris]

Camera jitter occurs when something changes at a different interval than the framerate

such as when you follow a non-interpolated rigidbody

[wheat spruce]

internal class PaintableTexture
{
  public RenderTexture Tex; // texture which the player has painted color onto

  private ComputeShader _painter; // to compute the texture
  private PaintBrushInfo _brush; // properties of the paint brush (brush positon, paint/erase state, size)

  public PaintableTexture()
  {
    TextureExtensions.CreateRenderTexture(out Tex);
  }
}```Is it possible to have some sort of custom texture class? I've got something like this, and I like the idea of making this class itself exist like a normal texture

few forum posts ive seen say its not possible to derive a class from RenderTextyre

[dry tendon]

Hey I have recently started with unity and I have an weapon, reload and gun switch function. Tho when I switch the gun I have to shoot before the ammo and mag text updates on screen. How do I fix that?

[still jungle]

"exist like normal texture" if you mean that it have to be stored as an asset as a custom Texture, you can apply custom extenstion and write scripted importer for it

[dry tendon]

The SelectWeapon function is in a different script

[thin aurora]

This script seems to do multiple things. Behaviour of a weapon, drawing UI, and animation of a weapon.
I could give an answer on fixing it, but the real answer would be that you should separate this script into three different scripts that communicate to eachother through events, rather than compacting them all into a system that now heaivly relies on eachother.

That way you also have your own Update method and you can fire without worrying of the UI, for example

[dry tendon]

That sounds complicated

[soft shard]

Looks like your only updating your UI in Update wheen you shoot, you could move it to a function and have that function called from OnEnable, or what I like to do, is setup an event and have UI in a different script, that way other systems can trigger a UI update without needing to go through other logic that eventually updates the UI

[wheat spruce]

I just mean so "PaintableTexture" itself would be RenderTexture, that way I can write the code it needs to do its task inside of the class, but then I can just give the material the PaintableTexture as if it was a normal texture

[thin aurora]

Making three scripts rather than 1 is complicated?

Honestly, it sounds like you might need to take more time learning C# basics if this confuses you

Events are quite basic

[dry tendon]

I mean yeah the script in gerneral has multiple functions that are all for the weapon. Splitting every single one in another script would be like +9 scripts

[heady iris]

"complicated" is when one god-object does everything (:

[thin aurora]

That sounds like a very good idea

You should look up 'KISS'

Or 'SRP', which is also applicable

https://www.bytehide.com/blog/kiss-principle-csharp
https://www.c-sharpcorner.com/article/single-responsibility-principle-srp-in-net-core/

[still jungle]

or apply the MVC pattern, and split your code, so you have full controll of what happens and when

[heady iris]

i really want to make a game that strictly follows MVC

probably alongside trying out rollback multiplayer

[still jungle]

first you have to find good guidance to apply it for unity which is a hard task itself

[thin aurora]

In short, you should have a script that handles your input (not necessarily tied to your weapon, just a general input listener), if you fire you tell your weapon component to fire. When you fire, you call an event "OnFire" and your UI hooks onto this event and updates accordingly with the new bullet count. Your weapon class can also play the animation. This is coupling done right.

If this is confusing, there is a server full of people who can explain the idea

[dry tendon]

So from what i understood I should make a new script for every single function that does something and make them communicate

[thin aurora]

You don't necessarily need an event here, but why would your weapon care about the UI? The UI cares about the weapon because it needs to know when and what to update on fire, so therefore the role is reversed with an event

[thin aurora]

Not every single function, just the "categories" you could say

So general input, the weapon's firing behaviour and animation and the UI would be a good start

You could put the input into the weapon, but why should your weapon care about input? It cares about how it should behave

[still jungle]

well if you want to store your PaintableTexture as standalone custom asset of RenderTexture, you suppose to use ScriptedImporter, or change the approach to use it as a normal RenderTexture and keeps some data in scriptableObject

[dry tendon]

I do think thats right but I would have to reference almost all scripts in the weapon script for stuff like this

[thin aurora]

You can do this, but instead of calling Reload you get the current weapon of the player, find the Weapon component or whatever you call it, and call Reload

This isn't scalable anyway. Would you have this code in every single weapon class of every weapon? 🤔

[dry tendon]

No I have made an general weapon script which goes on every gun, where I can adjust all settings like the fire rate, ammo mag and so on

[balmy plume]

pretty sure it is interpolated

[dry tendon]

So all I would have to do it add the weapon script change settings and done

[wheat spruce]

@dry tendon

public class YourWeapon : MonoBehaviour {
void Update() {
  //here is where you would call the different Weapon classes
}}

public class WeaponUI {
//functions that update the UI
//ie to update the ammo count
}

public class WeaponInputEvents {
//events that occur when the player presses buttons
//ie reloading
}

public class WeaponFunctions {
//functions the weapon will use to do its thing
}```Imagine having something like this

[dry tendon]

Alright

[still jungle]

        {
            nextFire = 1 / fireRate;

            ammo--;
// < -- move it here?
            magText.text = mag.ToString();
            ammoText.text = ammo + "/" + magAmmo;

            Fire(); // just move the fire up
        }```

anyway just fixed according to your question the fire have to execute before you change the ui, so just move the fire up

[dry tendon]

Oh wait lemme try

[dry tendon]

Alright if I switch the gun once now it works but once I switch them again it doesnt update until I fire again

I mean I thought about updating the text every few seconds but that would just waste performance

[mossy shard]

How come i only sometimes get this error:

and it doesn't effect anything, everything works perfectly

it just gets on my nerves

i have checked the line where the error appears, the sizes, everything is perfect and works normally, but it just decides to pop up sometimes

[latent latch]

If you're not sure of an error implies, it's worth atleast a google to give you an idea

[still jungle]

because the logic for updating UI only execute when you press fire button?

[dry tendon]

Yea just noticed

[mossy shard]

it's due to the sizes

of my lists

the exact error speaks of a node that has this error on a specific x and y position, but it works perfectly

[dry tendon]

I do think an ez fix would be this

[still jungle]

just place the code in switching logic

[latent latch]

If you're making an infinite type grid, you don't need to populate every index. You should be using the list as a lookup table and only populate/access what's actually instantiated

[still jungle]

anyway you should separate UI logic from the controlling logic

[dry tendon]

Yea i am on that too

[mossy shard]

that's the problem , it's not infinite

and that it only pops up SOMETIMES

by this point, i believe this is no longer a logical issue but rather an emotional one 🙏🏻 🙏🏻

[still jungle]

if it repeats it means there is logic behind it, so it can be recreated and tracked down

[mossy shard]

i was jokin, :))))

[dry tendon]

Do you think the animation of reloading should also be in the reload function?

[still jungle]

according to your code standard yes, you can place it in reload but dont forget to first reset the animation then set it to play

but in this case your reload will reload the ammo instantly and the animation will keep playing and can be interrupted

[dry tendon]

Im pretty sure you cant press anything until the animation ends

Except walk

And sprint and jump

[still jungle]

too much "ifs" to even read the code, i assumed that you dont have implemented it since you ask for it. Yest there is logic that prevent reloading when the animation is playing.

[dry tendon]

I dont even know if the timer is useful

I have it set to 3 sec but that doesnt make sense because you can not reload while the animation is playing

[still jungle]

its up to you to program the logic, if you dont need it then remove it

[balmy plume]

oh man finally the stutter is gone after implementing cinemachine vcam

[halcyon swallow]

if i do FindgameobjectwithTag and their are multiple objects sharing that tag
will it create errors? or just pick one of them

nevermind it returns an array instead

[cosmic rain]

You're probably using the plural version of the method. The singular one would just return the first object it finds.

[dusk apex]

Unless you've got to do that perhaps consider referencing the object through the Editor inspector or when instantiated, if created during runtime.

[halcyon swallow]

speaking of instantiation
i have some little capsules that duplicate themselves by instancing their own prefab
but the duplicates that are instanced dont have a reference to their prefab
i tried Resources.load() but that only works once, second generation capsules are also missing the reference

[rain minnow]

what do you mean by, "reference to their prefab?"

an object instantiated from a prefab does not have a link or reference to the prefab (unless you manually assign it upon instantiation) . . .

[halcyon swallow]

the little capsule contains istelf as its own prefab
but the instances of those instances are missing it

i tried calling resource load in the awake function but im confused why it only works once

i then thought awake was just buggy so put it in update but that ddint do anything either

[rain minnow]

so in the first pic, the inspector is the Creature prefab with the same Creature prefab as the Creatureprefab variable?

[halcyon swallow]

yep

are prefabs not allowed to call themselves or something?

[rain minnow]

they (the prefab) doesn't call anything, but you can store a prefab as a variable in a script attached to the same prefab . . .

[halcyon swallow]

i found out that putting Resources.load inside of the instantiate function worked
Even though that makes little sense

[rain minnow]

here you go; i just tested it. this is a prefab with its own prefab as a variable. i made the prefab spawn itself (using the variable) every five seconds and it worked. each instance had the prefab variable assigned when instantiated . . .

[halcyon swallow]

weird

maybe i have some random line of code somewhere preventing it from working like that

[rain minnow]

huh? Instantiate already creates an instance, why are you loading using Resources?

also, you can't edit the Instantiate method. how are you creating the instance?

[halcyon swallow]

GameObject child = Instantiate(Resources.Load<GameObject>("Creature")
works
creatureprefab = (Resources.Load<GameObject>("Creature")
GameObject child = Instantiate(creatureprefab) does not

[rain minnow]

it doesn't work, as in, the prefab variable is empty, right?

[rain minnow]

i just tested this and it worked

    private IEnumerator Start()
    {
        yield return new WaitForSeconds(5f);

        var instance = Resources.Load<Projectile>("Projectile");
        Instantiate(instance, transform);
    }```
each instance still had a reference to the prefab they spawned from . . .

[halcyon swallow]

weird
i have no idea why my code is fucked 🤷‍♂️

[rain minnow]

why are you using Resources in the first place? typically, you place the prefab in a variable and instantiate that . . .

[compact spire]

Hey everyone, I'm trying to setup a runtime scaling widget and I can't seem to get the algorithm correct for dragging the single axis handles with the mouse along one axis. Anyone aware of a good example they can point me towards?

[long flicker]

is there a way to make a rawimages size expand when hovering over it

im guessing it would be done with an event trigger?

[thin aurora]

Don't crosspost your question

Just because there are multiple code channels doesnt mean you can post in all of them

[long flicker]

i didnt mean to send int his one

[quick token]

is there a way to have an object follow another objects position, without having it be a child (so it doesn't copy the scale and rotation)

for now im just using a general script i made. but i feel like i remember unity having a built in way of doing it

[quartz folio]

A position constraint

Or any of the other constraint components

[quick token]

oh right, i didn't install the animation rigging package yet

thanks for the help, i thought unity had some kind of component for it lol

[quartz folio]

You don't need to install a package.

[void basalt]

I have a 144hz monitor and I don't seem to have any of these jitter problems that everyone else has. You don't need cinemachine to make unity games run smooth.

[fervent badger]

Potential culprit:

using UnityEngine;

public class DerivativeRotation : MonoBehaviour
{
    [SerializeField] Transform Target;

    private void Update()
    {
        transform.eulerAngles = new Vector3(0, Target.eulerAngles.y, 0);
    }
}

The player is taking the rotation of the camera

[fervent badger]

Yes, but I prefer the Cinemachine solution because it's less of a burden

I'll come back to this later. Just had a mental breakdown from this project

[void basalt]

Ideally you should be rotating your rigidbody via either torque or angularVelocity, but I can still get perfectly smooth non jitter movement in my unity projects by forcing the rotation for my first person controllers. I'd imagine cinemachine might be causing issues for you.

[wintry crescent]

Hey just to double check, I'm not crazy that this is the best way to ensure a GameObject/component is valid?

if (myGameObject != null)
{
    if (myGameObject) 
    {
        myGameObject.DoStuff();
    }
}

this double if structure seems weird

[balmy plume]

since when does gamObject return a Boolean?

[wintry crescent]

since always, I think

[vestal arch]

you could just combine them, but in this case, you only need 1. both checks do the same thing

[vestal arch]

it has an implicit boolean conversion.

[balmy plume]

oh that makes more sense

[wintry crescent]

why do I remember that I need to check it for null...? was it for components?

[vestal arch]

see the examples: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Object-operator_Object.html

[robust dome]

i think he is looking for TryGetComponent

[vestal arch]

the boolean check does the same thing as the null check

[balmy plume]

if ur checking for null already then why exactly are u checking for Boolean ?

[vestal arch]

for GetComponent, if it doesn't exist it returns null
both null and invalid objects in unity compare equal to null, and are falsy, while valid/existant objects compare unequal to null, and are truthy

[quartz folio]

https://unity.huh.how/unity-null

[wintry crescent]

because it can be not null (a reference to a destroyed object for instance) but still isn't a valid object

[quartz folio]

Huh I just noticed I says native C#, that should be native C++, but I'll probably remove references to the language from that sentence entirely

[quartz folio]

Read the resource above

[balmy plume]

dude cs is confusing

[thin aurora]

It's not, Unity is

Implicit conversion is not something you should just randomly add like this

[vestal arch]

but it will still compare equal to null; that behavior is overloaded

[balmy plume]

it was my understanding that once an object gets destroyed the reference becomes null like in any other language

[thin aurora]

Nobody would realize that an implicit conversion of a boolean checks if it's destroyed

That's just horrible practice

[wintry crescent]

it doesn't seem to answer my question though

[quartz folio]

That's not how any language works

[vestal arch]

destroying an object isn't really a thing in most languages
in c/c++ nothing becomes null, they become invalid pointers

[thin aurora]

Even better, Unity would have been a lot better if it didn't override the equality check and added implicit boolean conversion, and just added an isDestroyed boolean to check if a gameobject exists

But no, we have broken equality checks instead

[quartz folio]

The equality operator already checks for both real null and object lifetime

[thin aurora]

Broken because half the equality checks no longer work the same way as == I should specify

[quartz folio]

The implicit cast to bool is identical

[balmy plume]

so the only way to check the validity of a GameObject is this implicit boolean check?

[thin aurora]

AFAIK yes (and == / !=)

[vestal arch]

public implicit operator bool() {
  return this != null;
}

[wintry crescent]

is there something else that I might be mistaking it for, then? I can remember that I learned this double if structure for a reason

[quartz folio]

I've never seen this before you posted it

[vestal arch]

idk why you'd have a double if structure like this for any kind of validity check

[wintry crescent]

that's pretty weird...

[vestal arch]

if anything it'd be a single if with 2 conditions ANDed together

[simple egret]

Yep never seen this kind of structure before either, both do the same thing for types deriving UnityEngine.Object

[wintry crescent]

wish they fixed that, though

[quartz folio]

They can't

[thin aurora]

Can't fix without breaking everything sadly

[simple egret]

These are not overridable so they can't

[wintry crescent]

how about when CoreCLR gets here?

[quartz folio]

Doesn't change anything

[vestal arch]

isn't is a syntax thing, not an operator? it wouldn't be operator overloadable

[thin aurora]

is is pattern matching, so not overrideable

[wintry crescent]

it'd be pretty cool if ?. worked, though

[quartz folio]

They may choose to refactor this for U 7, requiring everyone to port their code, but I don't have my hopes up

[thin aurora]

People often say that you should prefer is null over == null but that would only make sense if you used a broken null comparison like this

Also is is not really supported in Expressions if you care about that, so it can't be applied everywhere

[wintry crescent]

wait, so it CAN be done?

[vestal arch]

i think they mean to not use the overloads

[wintry crescent]

I associate coreCLR with u 7 because if it's not here when u7 is here I'm gonna cry :(

[simple egret]

Given that they redo the whole Unity object lifetime system from scratch, yes. But that's a huge task, and they probably won't

[sleek bough]

You can still use it just fine if you remember to null the references of the object you destroy. It could be a problem though if anyone else working on the project and not aware of it.

[quartz folio]

By requiring every null check in user and internal code involving a Unity Object to be changed

[wintry crescent]

but that won't make the .? work, would it

[simple egret]

It would, ?. compiles into a bunch of is not null checks

[wintry crescent]

but how would a destroyed object become null then

[vestal arch]

wouldn't that not work with references not being turned into null

[quartz folio]

It wouldn't, you'd need to still check a property to see if it was destroyed

[wintry crescent]

exactly, ugh :C

[quartz folio]

But at least you would know that null checks would actually be reference checks and not an expensive jump into native code

[simple egret]

Yeah unless they program their own thing to "inject" a supplementary check (with a source generator and an interceptor) it's not doable

[wintry crescent]

yeah I don't think that would happen

[quartz folio]

We've got an extension method in our project that does the null check and swaps it for a real null so after that point you can use the modern null operators. But most of the code is ECS so it's not used in many places

[thin aurora]

Yeah I feel like you might be best off making some inheriting class on Monobehaviour that overrides the null check a second time and adds an isDestroyed boolean

Unfortunately this doesn't work for purely Component inherited classes, though

[unique delta]

If i run this code i get this outpout: 1 , instead of "A"https://pastebin.com/mcKjnCvt

[thin aurora]

Well, I don't https://dotnetfiddle.net/5jN1MH

So I suggest you debug your file and make sure the code is saved and compiling

From the little you shared I get the feeling your editor is not configured, in which case perhaps you might be able to share a screenshot of your editor window to verify

[balmy plume]

not that there is anything wrong with the code, but whatever you are trying to achieve with the code there has to be a better way to write that code to be more user friendly

[thin aurora]

Can't really give my opinion on complexity since this more or less looks like pseudo code and can be anything

[wheat spruce]

I've got my tilemap system to set the material type of each tile (indicated by colour), the goal now is to construct the mesh to represent the terrain.
What I'm unsure of is what would be a decent approach for that.

1: I could generate a different mesh for each material type, like what I did in the second image, then later put all the pieces back together
2: instead of doing it separately, maybe something like marching squares, I go over each tile, figure out what should go there and construct the whole mesh in one place

Im leaning towards 2, just as marching squares seems like they'd offer a lot of benefit down the road (especially as I've got a planned idea that will use marching cubes)

[unique delta]

Sorry for the delay. If i put the numbers instead of index and second index it works. Do you know why?

[balmy plume]

honestly idk it works fine for me maybe check ur ide configurations

[unique delta]

i don t think that s the problem

[balmy plume]

try running the script in an online compiler

[simple egret]

<@&502884371011731486> scam

[heady iris]

i need to implement marching * at some point

(maybe marching simplexes in 3D)

it'd be worth learning for sure

[steady bobcat]

GPU instancing and batching will easily make drawing the tiles faster (if they all are a quad)

[sacred python]

how can i map the uv according to the mesh?
i dont want each face to be painted on

[heady iris]

if you want to create a UV map, you'd do that in Blender

The default cube's UV map has each face use the entire texture

you want an actual unwrapping of the cube

[hexed pecan]

Default coob is unwrapped:

[sacred python]

ok bu what if i have a iregular mesh? like somehing impoted?
later i dont want to use the cube anymore

[heady iris]

in Unity, I mean

[hexed pecan]

Aah

[heady iris]

same deal: you'd create the UV map in Blender as part of creating the model

[hexed pecan]

I always associate "default cube" with blender

[heady iris]

true, it made me think of Blender too :p

[heady iris]

you'd just make sure that no faces are overlapping

[sacred python]

hmm i understand
thank you guys

[wheat spruce]

yeah, its what I'll do. Made a start designing it in Houdini, gives me instant feedback to see if what I'm writing will work. So far so good with it finding the 4 points for each square

[rotund perch]

is there any possible way to call a delegate remotely? (not in the script)

I don't entirely understand delegates yet but I understand the basics of how to use them

[heady iris]

you can pass a delegate typed object around like any other object

public void RunIt(System.Action action) {
  action();
}

this method will accept any zero-argument function that returns void and immediately execute it

[rotund perch]

  public delegate void OnPlay();
  public static event OnPlay onPlayStarted;

I have this in one script, editorManager

I change scenes then want to call this without an editorManager using my TestLoader script, but it says I can't do editorManager.onPlayStarted(), only use += or -= unless inside editorManager

[heady iris]

event only lets the type that owns it invoke the delegate

anyone can add or remove callbacks

If you need to be able to invoke onPlayStarted from anywhere, just add a public method that invokes it

[rotund perch]

yeah I've got a public static void startPlayDelegate() => onPlayStarted(); in editorManager but I'm getting

NullReferenceException: Object reference not set to an instance of an object
editorManager.startPlayDelegate () (at Assets/Scripts/editorManager.cs:984)
TestLoader.Start () (at Assets/TestLoader.cs:16)

[wintry crescent]

I have a script (not written by me and pretty complex so it's tough to copy the relevant parts here) that derives from MaskableGraphic. Maskable (the property) is set to true, but the graphic isn't being masked, while its child components (normal text/images) are being properly masked - does anyone have an idea where should I start looking to figure it out?

[rotund perch]

are you using a custom shader?

@wintry crescent

[wintry crescent]

nope

[rotund perch]

huh, that's usually the culprit for me

I would check the docs for MaskableGraphic

[thin aurora]

Unrelated but please get into the habit of using PascalCase for class names and method names. camelCase is used in Javascript

That said, what specifically is line 984 here?

[wintry crescent]

I have a script that makes a rounded rectangle - it works AS the mask, but it doesn't work when it's being masked

[thin aurora]

Note that if this is an event, if nothing is subscribed to it it will be null

[rotund perch]

that's the function that I showed with the lambda

[wintry crescent]

as you can see, it masks other things properly...

[thin aurora]

It can't be null so that's not it

Again, unless onPlayStarted returns a delegate or event

Oh I see the code above now

It's an event

[simple egret]

Given the name, seems like an event yep

[thin aurora]

-public static void startPlayDelegate() => onPlayStarted();
+public static void startPlayDelegate() => onPlayStarted?();
or
+public static void startPlayDelegate() => onPlayStarted?.Invoke();

[rotund perch]

Maybe my code isn't subscribing to it in time

what does the ? do?

[thin aurora]

Null coalescing

[simple egret]

(Runs the stuff after the ?. only if the stuff before is not null)

[rotund perch]

oh cool so I don't need to have a if(x != null) thing

[simple egret]

Yup

[rotund perch]

that will save me a lot of space

[thin aurora]

Or in this case ?() is syntactic sugar for ?.Invoke() I believe

[simple egret]

?. compiles into a full blown if statement, if I remember correctly

It's syntax sugar, so there's no performance difference

[rotund perch]

Ok so the issue is that when I do the load function, it instantiates a bunch of objects, but then the objects didn't have time to subscribe to the event. I was using a Start() function to subscribe to it but if I switch it to Awake() it works

[heady iris]

note that you should not use this for Unity object types -- it'll only catch a genuine null

a destroyed unity object compares equal to null, but that's not an actual null reference

[heady iris]

I know that Unity does some ~evil stuff~ when doing UI masking. it creates a copy of the material that uses a different shader.

I'm not sure where I'd start looking though

[ashen oyster]

Hey is there a nicer way to do this?

    private bool _jump;

    private void Update()
    {
        if (_input.Player.Jump.triggered) _jump = true;
    }

    private void FixedUpdate()
    {
        if (_jump)
        {
            _jump = false;
            PhysicsJump(); //dummy function
        }
    }

[rotund perch]

is this the new input system?

[ashen oyster]

Indeed

[rotund perch]

ok

I'm pretty sure there's a buttondown equivalent

let me check

[vestal arch]

you could do PhysicsJump in the if in Update directly, depending on what PhysicsJump does

[vestal arch]

that's the equivalent with actions

[knotty sun]

Only make the input an event but otherwise the logic does not change

[ashen oyster]

No thanks I'm using the new input system :)

[rotund perch]

Yeah I know I'm talking about an equivalent of ButtonDown that exists for the new one.

There's a WasPressedThisFrame() function for InputActions

[rotund perch]

that works too

Not sure if WasPressedThisFrame works for fixedUpdate though

[vestal arch]

input is frame-bound
checking for press/release frames doesn't work

[vestal arch]

triggered for a button type action is one of those equivalents

[ashen oyster]

Physics jump edits the velocity, but in fixedupdate other things edit the velocity by assignment as well

So it's crucial where it appear in the fixed updat function

[vestal arch]

then this is probably fine

[ashen oyster]

Well yeah it's fine but I hate how it makes everything so messy 😭

[vestal arch]

well how exactly do those "other things" edit the velocity?

do they not respect the y velocity or something?

[ashen oyster]

They don't

If you hit your head it gets set to 0

or if you touch the floor!

so it would get set 2 -> 0 -> update position, then it doesn't jump

[vestal arch]

why not just let the physics system handle that?

[ashen oyster]

that's a non-option

I'm making a precision platformer

[vestal arch]

how is that a non-option?

you're literally just redoing what the physics system would already do

[ashen oyster]

I'm not gonna explain why, just know I can't

[vestal arch]

well that just sounds like https://xyproblem.info now

what's the issue when letting physics handle collisions?

[ashen oyster]

It's not, I need fine tuned control over all movement. The physics engine is just in the way

I do use a kinematic body
