I've not heard of the physics queries, and, I thought using physics like that was too computationally expensive. Anyway, this is for a class assignment due today, so not enough time for a complete overhaul. I am trying to add a new collider I can reference in the inspector as a SerializeField, but the field is not showing

[rigid island]

btw this is a #💻┃code-beginner . Here you're expected to know the basics of unity..
queries are like raycast, or overlapsphere etc.. there is nothing much to "overhaul"

Collider field should work just fine in inspector, how exactly do you plan on using that to help though ?

[fading swallow]

its working now, there was just an error I did not catch keeping it from updating. I'm sorry I did not realize this fell outside the real of general. Just a CpE taking a game dev elective.

It does not seem it will work since OnTrigger doe not keep track of which collider on the component was entered only that a collider on the component was entered.

[rain minnow]

The Collider is the component; do you mean GameObject? You should place collliders on separate GameObjects attached to your main GameObject . . .

[fading swallow]

Thanks yeah a few people have said this. Thankfully for my grade for today, i was able to assign a layer mask to it in the project settings. Which is a bit of a waste of a layer since there are only so many. but at least it works for its purpose today.

done

i wanted to know if maybe i can upgrade it and make cleaner

[rigid island]

to make it cleaner you should split it into smaller methods, each method should perform a specific functions instead of being all crammed in Update .

Another thing you should probably do is apply rigidbody forces in FixedUpdate

also lerp can use some fixing but no biggie. https://unity.huh.how/lerp/wrong-lerp

thanks

ill apply these tips

Hi! Sorry if this is the wrong channel, I'm not quite sure where to put it. I’m working on a Unity UI system where a shop item can be dragged and dropped onto a border collider to trigger an action. The drag works, but the trigger doesn't fire at all.

I’m dragging a UI element (inside a Canvas) using IBeginDragHandler, IDragHandler, etc.

That element has:
Rigidbody2D (Dynamic)
CircleCollider2D
CanvasGroup
Script with OnTriggerEnter2D(Collider2D other)

The border collider it should trigger has:
BoxCollider2D (Is Trigger ✅)
Rigidbody2D (Dynamic)

Both objects are on Z = 0
I'm using Physics2D, not 3D
The dragged object is a child in a prefab, instantiated into the scene before dragging
The drag works, and the object moves correctly, but OnTriggerEnter2D never fires
I added debug logs — nothing appears

This is the part that isn't working:
private void OnTriggerEnter2D(Collider2D other)
{
    Debug.Log($"Triggered with: {other.gameObject.name}");
    ShopManager.current.ShopButton_Click();

    Color c = img.color;
    c.a = 0f;
    img.color = c;
}

[fresh sandal]

hey I followed your instructions, it works amazing now! Thanks!

@sterile reef the end result!

Now I have to find a way to keep the shadows static....

[sterile reef]

sweet!

[fresh sandal]

Not sure if I want the shadows anyway, oh welll...
Actually, I think I will tackle the shadow missing problem later

Light is such a pain to handle lol

[sterile reef]

instead of disabling the gameobject you can make a new layer WallHide and exclude it from your camera

by setting the layer of the gameobject to be hidden

though i dont know if that also takes away shadows

[fresh sandal]

Interesting, lets see....

Nah, that did not work. Worth the try though

It seems I need to use the ShadowCaster layer trick

[thin pecan]

It didnt work but thanks

[rain minnow]

Canvas UI doesn't work with rigidbody, colliders or collisions. Those are for scene GameObjects . . .

[civic girder]

I'm working on a multi-step (few steps at most) action system for a grid based TRPG.

At each step of the action I want different things, example:

1) highlight valid tiles
2) if tile is clicked, do something
3) show a menu for the attack action if attacking is possible (ends a unit's turn) or just end a unit's turn

The issue is:
I want to allow the user to undo as long as the unit's turn is not ended (while they're still in the action).
This undo "reverts" back to the previous state.
However, I'm not sure how to do that.

Right now this is my pseudo code:

/// <summary>
/// serves as a memory for the action's stack. Helps with chain and undoing
/// </summary>
private struct ActionState
{
    public Action doAction { get; private set; }
    public Action undoAction { get; private set; }

    public ActionState(Action doAction, Action undoAction)
    {
        this.doAction = doAction;
        this.undoAction = undoAction;
    }
}

public override void TakeAction(GridPosition position, Action onMoveCompleteDelegate)
{
    ActionStart(onMoveCompleteDelegate);
    var initialState = new ActionState(() =>
    {
        //do
        MoveUnitToPosition(CastingUnit, position, CastingUnit.GridPosition);
    }, () =>
    { 
       //undo, do the reverse of the Do lambda
        MoveUnitToPosition(CastingUnit, CastingUnit.GridPosition, position);
    });
    // do the step and add it to the stack
    initialState.doAction?.Invoke();
    stateStack.Push(initialState);
    //create another state and show a menu
    PromptAfterMoveAction();
}

//called when the player presses the cancel button
public override bool CancelAction()
{
    //if no states exist, assume canceled
    if(stateStack.Count == 0) return true;
    var state = stateStack.Pop();
    state.undoAction?.Invoke();
    //indicates that all steps have been canceled
    return stateStack.Count == 0;
}

It works so far (early prototyping), but given that some of the logic involves UI (menus, highlighting grid tiles, etc), I'm not sure if this solution would bite me later.
I'm not looking for full-code solutions on here, I'm aware that this is specific to my design system, but what should I look into when dealing with such a mechanic?

[karmic stone]

Hello! I'm currently coding some interaction with unity's terrain using code and scripting api. (Heightmap, 2d float array specifically) I'm trying to get all points in the grid array thats between a min/max point given to the function as a float, and minus some area from their height. however, when doing this, i cannot get why my code, which is min inclusive, maxexclusive, creates a "grid square" that is so much smaller then the bounds that was passed, could anyone give me an opinion on what i did wrong? https://paste.ofcode.org/T2gaEzjbwhL2ahGBKYsKyh
I know that the grid array index is cell - 1, but then the cast means that every part is always the cell below where the area is. cell -1 (for index) then +1 (because i dont want to edit things outside the bounds) for min. for max, its exclusive, so i want it to be 1 above whereever the last index to change is. -1 for array index, and then +1 because i want to edit things right below max value.

[copper inlet]

Wow that's a nice code but try go harder I am getting my codes with this issues of yours

[karmic stone]

i didnt understand your sentance, do you mind trying to say it in a different way?

[steady bobcat]

I would guess that the method to set uses texel size and not world size or some other scale issue. Is the min/max point correct then (its hard to see in your screenshot)?

[karmic stone]

in the screenshot, the green is the index min/max converted to world coords, then created into a bounds. the red is the bounds given (bounds being minx/z and max x/z). it depends on Heightmap texture size and terrain size.

[steady bobcat]

does that green gizmo match the mesh change? again i cannot tell 😆

btw you can use Vector2Int if you wish and id use many args instead of a Tuple here

[karmic stone]

heres another screenshot, and i do use vector2int, once i convert the floats to ints.

that green matches the minx,miny, maxx , maxy calculated in GetMinMaxHeightIndexes

the red matches the area tuple given as an arg to the GetMinMaxHeightIndexes

the green SHOULD be the Minx/y closest to the minx/y of the area, and the maxx/y closest on the outside of the bounds.

[steady bobcat]

new Bounds(minCellWorld + (maxCellWorld - minCellWorld)/2, (maxCellWorld - minCellWorld)/2)
here you half the size too?

and go ortho in scene view to make this not shit to look at plz

[karmic stone]

new bounds(center, extents), center being min + max - min /2

[steady bobcat]

its size not extents?

[steady bobcat]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Bounds-ctor.html

[karmic stone]

ahh, dumb of me. thank you

[steady bobcat]

you can make your life easier by making this a vec sooner and doing a vec/vec or vec * vec operations btw

also you can do (Vector2Int, Vector2Int) to do a tuple

[karmic stone]

Ahh, do it right after minusing the transform.position, thank you rob.

[steady bobcat]

no prob

[karmic stone]

Well, fixed the issue, problem is im trying to do this with a big terrain, creating a smaller terrain with same detail makes my hoeing HIGHLY more accurate

[cloud tundra]

Im setting up procedural room generation with prefab rooms, but i am currently try to avoid overlap with box colliders, but this currently just stops generating any room as it some how detects overlap

Procedural Generation Issues

[young yacht]

if (Gamepad.current == null)
        {
            screenMouse = playerInput.UI.Point.ReadValue<Vector2>();
        }
        else
        {
            screenMouse = Mouse.current.position.ReadValue();
        }

        screenRay = Camera.main.ScreenPointToRay(screenMouse);
        crosshairRect.transform.position = screenMouse; 

        timePlayed = Time.realtimeSinceStartup;
        aimRig.weight = Mathf.Lerp(aimRig.weight, aimWeight, Time.deltaTime * aimSpeed);

can anyone help here? i got a virtual mouse script on my crosshair and i'd like to use the gamepad right stick to move that same crosshair, its working but thing is when i stop the stick motion it snaps back to the left screen corner

i might be overriding something

[civic girder]

what's the type of screenMouse?
if it's vector3 or vector2, it defaults to 0,0 if unset

[vestal arch]

it can't be unset

[civic girder]

yes

hence getting on the left bottom side, an easy way to fix this is to only call the logic:
crosshairRect.transform.position = screenMouse;
IF the cursor/gamepad actually moved.

IIRC, for Mouse, there is a "hasMouseMoved" method or something like that, returns a bool if it has moved or not. (If not, get the mouse delta and check that it is not 0,0)

I'm not sure about gamepad, you might need custom logic if such a method doesn't exist

[vestal arch]

if there is a gamepad, you use the mouse?

[civic girder]

personally no, but sometimes it's good to support different input methods.

In disgaea 5 for example, I played it mostly via keyboard
However, when I'm eating/feeling lazy, I just play with mouse while using my other hand to eat or rest.

So I'm not questioning OP's logic, he just needs better handling

[vestal arch]

....are you answering me?

im not asking you

[civic girder]

I know

[vestal arch]

no clue what you're trying to say then lmao

[young yacht]

its Vector3

[young yacht]

if gamepad is null

was testing to see if the problem was using the same input

still snapped

[young yacht]

personally i always prefer single player games using gamepad, unless they're UI heavy

[vestal arch]

look at your code again
if Gamepad.current is null, you read playerInput.UI.Point
if it isn't, aka there is a gamepad, you read Mouse.current.position

[young yacht]

ah thats old code

sorry

was looking at a more recent version on my screen

[young yacht]

if (Gamepad.current == null)
        {
            screenMouse = playerInput.UI.Point.ReadValue<Vector2>();
        } else 
        {
            screenMouse = playerInput.Gamepad.Pointer.ReadValue<Vector2>();
        }

was looking at this

[vestal arch]

gotcha

[young yacht]

i also checked unity's virtualMouse script and found a function they use to update the motion

if (Mathf.Approximately(0, stickValue.x) && Mathf.Approximately(0, stickValue.y))
            {
                // Motion has stopped.
                m_LastTime = default;
                m_LastStickValue = default;
            }
            else
            {
                var currentTime = InputState.currentTime;
                if (Mathf.Approximately(0, m_LastStickValue.x) && Mathf.Approximately(0, m_LastStickValue.y))
                {
                    // Motion has started.
                    m_LastTime = currentTime;
                }

i thought the problem was that m_LastTime = default

tried commenting that code but its still snapping

[vestal arch]

have you tried debugging the values you get from that?

are you sure it can read directly as a pointer?

[young yacht]

yea good idea

let me try

[young yacht]

its reading as a single value

[vestal arch]

...no clue what you mean by that

[young yacht]

if (Mathf.Approximately(0, stickValue.x) && Mathf.Approximately(0, stickValue.y))
            {
                // Motion has stopped.
                m_LastTime = default;
                m_LastStickValue = default;
                Debug.Log(m_LastTime);
            }
            else
            {
                var currentTime = InputState.currentTime;
                if (Mathf.Approximately(0, m_LastStickValue.x) && Mathf.Approximately(0, m_LastStickValue.y))
                {
                    // Motion has started.
                    m_LastTime = currentTime;
                    Debug.Log(currentTime);
                }

[young yacht]

i mean this

[vestal arch]

why are you debugging the time

oh i wasn't specific when i said to debug "the values", sorry

[vestal arch]

i mean the values here

[young yacht]

oh xd

mouse values

gamepad values

maybe best way really is to just have a boolean check if the stick is moving

[vestal arch]

yeah this seems like a delta, not a position

[wise kindle]

using UnityEngine;

[System.Serializable]
public class Connection 
{
    public Node from; //The node where the connection starts
    public Node to; //The node where the connection ends

    public bool bidirectional;
    public float weight;

    public Connection(Node from, Node to, bool bidirectional)
    {
        this.from = from;
        this.to = to;
        this.bidirectional = bidirectional;
        this.weight = Vector3.Distance(from.position, to.position);
    }
    public Connection(Node from, Node to, float weight)
    {
        this.from = from;
        this.to = to;
        this.weight = weight;
        this.weight = Vector3.Distance(from.position, to.position);
    }

}```

This is a Connection Class, there is also a Node class that has a Connection list in it, the issue with the Connection list within the Node class is that it causes infinite nesting, which severely damages performance in unity, how could I avoid this infinite Connection nesting?

[placid edge]

how do i make a raycast ignore all collisions except two types of objects/layers?

[robust dome]

you can use a layermask.

[vestal arch]

the structure isn't an issue in itself, at least one of them is a ref type

are you traversing the structure recursively or something? if so you could keep a "visited" set/list to make sure you don't backtrack

[placid edge]

they also have different layermasks, basically i want to make an enemy that doesnt notice the player if there's another enemy standing between them, but in doing so and setting the layermask to enemy it's detecting itself as they are all copies

[vestal arch]

make the raycast start a little outside the enemy shooting it

[robust dome]

if you want that behaviour it would not make sense to use a layermask then.

you could simply use a CompareTag and see if it hits the enemy or player

then you would have to do what Chris recommended so that your rc is outside of your own collider

this should do the trick.

[woven pendant]

why is this happening

[spice estuary]

Kinda hard to tell without knowing what your Ship script is doing

[woven pendant]

its just rotating the ship gameobject

it has children with rigidbodys, no gravity

and im testing now and its like the velocity is not local

[spice estuary]

If you change the transforms of a parent, the children will be affected

[woven pendant]

how do i get the velocity to also be local?

[spice estuary]

Dynamic rigidbodies don't really go well with parent/child relationships

since they are simulated through physics

[woven pendant]

oh

[placid edge]

it would work that way but the problem is that I have a lot of colliders on my 2d scene, and i need the Raycast/Linecast to ignore those and keep going until it meets either another enemy or the player. Some of these colliders also have their own layermasks ;/

[spice estuary]

That's what the layermask is for. You tell the raycast to test against colliders that are included in the layer(s). Then you can filter anything you want. If the enemy casting the ray is hitting itself, then move the raycast start position so that it isnt inside the source

Alternatively you can use raycastall which doesnt stop when it hits something, but instead returns everything it hits, then you can check what it hit and filter as you need there. A standard raycast is cleaner though, if you can make it work where it doesnt hit the source caster

[placid edge]

yes this solution is working much better thanks, the problem wasnt that it was hitting itself itsthat there's a lot of colliders in the scene it can hit that i dont want it to, so getting them all and filtering it until and if it finds an enemy is the way to go for me

[spice estuary]

Then supplying only the Player and Enemy layermask to the raycast should do the trick

[placid edge]

how do i do both of them, I can see that i can feed it an int that would serve as the number of the layermask, how would i be able to give it both numbers?

[spice estuary]

You can create a serialized field for example:
public LayerMask hitLayer;

then in the inspector it will show as a dropdown where you can select multiple things

then in the raycast you feed it the hitLayer where it asks for the layermask

[placid edge]

ive tried that but couldnt get it to work, where would I dynamically change the layermask?

i previously put it inside where it would detect that it hit said layer

[spice estuary]

It's something that is usually predetermined. For example if I have a script for an enemy that performs an attack, I have the serialized field already set inside the class

then in inspector I would assign which layers this attack should be able to hit

[vestal arch]

the int is the value of the layermask
a layermask is just a bitfield/bitmask wrapped inside a pretty struct

[placid edge]

yes, the order of the layermasks no?

[spice estuary]

Think of it as a whitelist you give the raycast

[vestal arch]

a layermask of 0 means nothing
a layermask of 1 means layer 0
a layermask of 2 means layer 1
a layermask of 3 means layer 0, 1
a layermask of 4 means layer 2

[vestal arch]

no

i think you're confusing 2 terms, you're calling "layers" and "layermasks" both as "layermasks"

[placid edge]

ah, it doesnt start at zero

[vestal arch]

it doesn't start at any value

it just is a value

or you could view it as being many values

https://unity.huh.how/bitmasks.html

[spice estuary]

It's easier to just think of it as a list of Layers

the raycast checks all colliders with the layers included in the mask

[vestal arch]

wdym you couldn't get it to work, getting the dropdown?

[placid edge]

wait a minute, so because the raycast is always aimed at the player, if i simply check to make sure that there isnt an enemy in the way, then that would work?

[spice estuary]

Yes that could also work

It depends what you use it for

If you need to know where you hit the player you would still need to include the player

[vestal arch]

that'd work yeah

[placid edge]

no i wouldnt need that

so i can just set the layermask to enemy and that should work? i think i just complicated this for myself for no reason 😭

[spice estuary]

Yes

anything you put in the layermask, is what the raycast will do hit detection for

[placid edge]

yes i think i overcomplicated it by thinking i needed to detect the player when its already aimed at the player and can simply do a function somewhere else if raycast doesnt detect an obstacle, of which it would only be an enemy

[placid edge]

however this layermask thing is hard to grasp, how does this sequence work?

youre right i dod confuse layers with layermasks

what layermask would i need to use to get the 6th layer which would be the Enemy Layer

or is it something completely different

[spice estuary]

It's easier to just to make a public or serialized layermask variable 😄

then you have a nice UI where you select which ones it should be, and the nice magic works out the bit shifting for u

[placid edge]

ok im gonna have to look this up

[vestal arch]

did you check out #archived-code-general message

[vestal arch]

6th, or layer 6?

[spice estuary]

Feel free, I almost never need to know the nitty gritty for what I've used raycasts for, but it can be very efficient in general for flags and other things

[vestal arch]

the former would be 128, the latter would be 64
but really you should just use the inspector UI to set it, much easier

[vestal arch]

it's just making a serialized field that's of type LayerMask lol

[placid edge]

its just hard to grasp for me 😭

its the layer number 6

so... layermask 64?

should I just write 64 then? its not like ill shuffle my layers around any time soon

[vestal arch]

did you check out the link i posted

[placid edge]

no i didnt lemme scroll up

[vestal arch]

no, you should check the box labelled "Enemy" when you configure the layermask from the inspector

[placid edge]

wait youre so right

i did that before

godammit

[vestal arch]

....we've been telling you to do that the entire time tho?

from way up here lol #archived-code-general message

[placid edge]

i have problems understanding things at times

;/

yep, works like a dream, thanks guys

cant believe i kind of had it at one point and deleted it all before coming here smh my head

[hardy pasture]

How to hide game objects in a generic way, similar to how when you press the eye button in the inspector?

[last quarry]

Is it important that they're not disabled entirely? Just hidden visually?

[hardy pasture]

Yes.

[last quarry]

Will need to disable the renderers then

[hardy pasture]

Also I want it to work in the editor: how when you press the eye symbol.

[hardy pasture]

My controls don't have the renderer components, they're OnScreenControls.
Well, I guess they're images specifically.

Also when I press on the eye in the editor, it doesn't seem to disable the images either but everything is not visible.

[last quarry]

So on a canvas?

[hardy pasture]

Yes, but not necessarily, I guess.

[last quarry]

Add a canvasgroup, make it transparent

[naive swallow]

Quick question about GLTFast - the documentation is creating a new GltfImport every time a file is loaded, but doesn't seem to use it after the .Load call. Is that necessary or can I re-use the same one if I have to load multiples? The documentation isn't clear either way - it just does them in every section, presumably to make each piece a self-contained snippet of code.
https://docs.unity3d.com/Packages/com.unity.cloud.gltfast@5.2/manual/ImportRuntime.html

[naive swallow]

Guess I'll just have to , but for that I need to actually get it to run multiple imports.

Previously, I was doing this with a Coroutine, but Gltfast is expecting async, and I'm not entirely sure how to "kick off" an async. I get the general concept of it, and I've used it before with async Start and the like, but this one needs to fire when a variable changes (a string representing a directory full of GLTF assets to scan through) which is done in the UI. I have the event and everything all wired up, the user picks a directory and it goes to an ordinary function OnPathChanged, which used to use StartCoroutine to kick off an IEnumerator that loaded the assets one at a time. But now that LoadMeshes function is an async Awaitable LoadMeshes instead. How do I kickstart an async outside of another async?

[steady bobcat]

you just call it and you can await it (as it returns a task) or do nothing or use .ContinueWith() to execute a delegate when it finishes instead.

[naive swallow]

I can't await it since the function that calls it isn't async, and I don't think I can call an async from a UnityEvent

[steady bobcat]

you surely can

async is not like a coroutine where it needs special handling to make the yielding work

[naive swallow]

I don't need this function to do anything after starting the task, I just need it to fart in an elevator on its way out. The task will start loading in the meshes as it goes and fire off events, isn't there a way I can have synchronous code just, queue and abandon an async?

[steady bobcat]

public async UniTask MyCoolAsyncFunc()
{
    await UniTask.Delay(100);
    Debug.Log("foo");
}

MyCoolAsyncFunc();
//do other stuff

ha got there in the end

MyCoolAsyncFunc().ContinueWith(() => Debug.Log("I get called after this is done"));

[naive swallow]

So, this warning can just be ignored? If I don't care about the results of this function I can just call it like this?

[steady bobcat]

yes

[naive swallow]

Neat

I can assign it to a discard to avoid the warning, it looks like

[steady bobcat]

If you use UniTask you can use .Forget() to make it shut up and log exceptions correctly
You may notice that if it throws an exception it wont be logged until you stop playing.

Unity are dumb and added Awaitable too late hence many of their packages use Task when you should not use it in your own code

I use UniTask in projects I work in

[naive swallow]

Does UniTask work with await Task.WhenAll?

[steady bobcat]

It has its own version

[naive swallow]

Okay, I'll see about getting that

[steady bobcat]

Also has helper functions such as:

someUnityEvent.AddListener(UniTask.UnityAction(async () => {}));

[naive swallow]

But as it currently is, Awaitable seems to not be doing anything. I'm gonna do some debugger time and see if that's my fault in the function itself or if it's just not starting the task

[steady bobcat]

avoid doing _ = AsyncThing(); and do AsyncThing().Forget() and also debug to see whats up

[naive swallow]

Okay, it seems at some point in my thread, an exception just gets lost to The Void

I was clicking through it and my entire debugger context just vorped into nothing

I'll go get UniTask

[steady bobcat]

Exceptions in other threads never get logged to the unity console so you want to debug + enable break on exceptions.
Or use the UniTask functions to run code elsewhere OR catch it fully and log them yourself.

[naive swallow]

Yeah, I've stepped on that particular rake before so I knew what to expect when it just silently died. I just kinda need the error to know what went wrong

So I'm gonna try out this UniTask thing

I have a TaskScheduler.FromCurrentSynchronizationContext() that uses the System.Threading namespace, can I just keep that or is there a UniTask equivalent?

[blazing wyvern]

I just spent 40 lines of code on an ADS script and i was just told about ternary operators

Apparently i could do it in like 10 lines

What the fxck

[naive swallow]

Fewer lines is not always better

[blazing wyvern]

I know, i know

[steady bobcat]

UniTask should be using the unity task scheduler already but they use their own things also using the update loop.

[blazing wyvern]

But it still bugs me how easy it could've been instead of me overcomplicating everything

I also learned about coroutines today :>

Probably the most useful thing i've encountered in a while

[naive swallow]

It's the GLTFast importer, it uses ContinueWith and passes TaskScheduler.FromCurrentSynchronizationContext() as the state to it.

[steady bobcat]

Ah, you can use .ToUniTask() and then continue with and not worry

Or in the continue with you can use await UniTask.SwitchToMainThread();

[naive swallow]

Is that an extension method somewhere I need to get? It doesn't recognize that function.

[steady bobcat]

the delegate can be async.

Actually im not 100% on if unitask will use the unity scheduler automatically 🤔

[steady bobcat]

Hmm I presumed it was a thing but perhaps no. Id leave the sync context arg then like they have or go back to the main thread like I said above ^

tis a pain managing this sometimes

Ha guess there is one

[naive swallow]

Aha! There you are you little exception

Now, to find out what it means

[steady bobcat]

Yay progress

[naive swallow]

Okay, found the source of the error

[naive swallow]

Turns out the answer to this one is "No, make a new one every time"

Okay, good news: Async stuff works like a dream, got all the meshes streaming in just as I'd expect.

Bad news: For some reason every east/west facing wall has been infected with a poultergeist

Almost certainly something wrong with my import settings from gltfast, kind of looks like mipmaps gone haywire? Maybe shadows?

It's the Triplanar shader I wrote

No idea why it worked with the TriLib imported mesh but not Gltfast but it certainly does seem to be a me problem, guess I have to go figure it out

[hexed pecan]

Seen similiar stuff when a mesh is missing tangents

[naive swallow]

Maybe TriLib did some sort of auto-correcting? Messing up my tangent math when generating these meshes is certainly within the wheelhouse of "Shit, I would do that wouldn't I?" and I've just never noticed?

Would explain also why it happens only on walls in a very specific orientation

How would I compute the tangents of a triangle, given the vertices and normals?

Looks like I need the Cross Product of the normal and world up?

So now I need to actually learn how to do a Cross Product because my mesh source does not have a convenient Vector3.Cross method

[steady bobcat]

Mesh has functions to do this
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Mesh.RecalculateTangents.html

If you can get it after loading that is

[naive swallow]

I probably could, but I think GetComponenting the mesh filter and pulling the mesh from it would be a significant drain on resources

but maybe there's somewhere further down the pipeline where I do have access to the mesh that I can do? A few frames of static is acceptable if it "pops in" later

[steady bobcat]

Why? It's already a mesh on cpu side and seems like you need to fix this

[naive swallow]

Success! I found somewhere later on in the processing chain that got the mesh filter and just slapped a RecalculateNormals function there and no more static

[naive swallow]

The issue was the GetComponent. There's a lot of meshes, and an extra GetComponent call would have noticeably slowed down loading, so I wanted to find somewhere else to handle that instead of at load

[steady bobcat]

Oh right I see, I presumed it was a few only

Where are the glb files coming from?

[naive swallow]

No, it's like, thousands. And GLTFast gives me the whole instantiated objects, not the meshes themselves

[naive swallow]

A Java program I also maintain so I definitely borked the math on it

[steady bobcat]

Probably the normals are bad? I forget if tangents are calculated or are imported

[naive swallow]

The normals seem fine, problems with those would be visible in the lighting. It's definitely my math because I'm forced to work in a really janky psuedo-vector data structure that sucks and has zero convenience functions

[reef garnet]

anyone here know how linearDamping applies to a rigidbody, like when calculating the resultant force how does it affect that equation

[vestal arch]

there's a formula on the 2d version's docs
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Rigidbody2D-linearDamping.html
not sure if this also applies to the 3d version but it probably does

[reef garnet]

hey thanks

[naive swallow]

So, now that I've got this fancy UniTask library, is there a way I could use it to queue up multiple functions, and run as many of them per frame as it can while keeping up a certain framerate? I have a bunch of stuff that uses AddComponents and other UnityEngine functions, so I can't offload it to another thread. Still, I'd like to make sure the framerate stays as close to 30 while loading them as possible. In a Coroutine, I'd keep a running tally of how long it's taken to execute each function and yield return null when that timer goes over 33ms. Is there a better way to achieve this with UniTask?

[steady bobcat]

well you could replicate the behaviour by awaiting the next frame via await UniTask.Yield();

[naive swallow]

Yeah, but I was wondering if there was some fancy way to queue up a bunch of synchronous functions like UniTask.RunOnThreadPool

Which would be perfect if I could multithread these

[steady bobcat]

well you can delay for an amount of frames so technically you could yourself "queue" up work over many frames at once

[naive swallow]

Yeah but the amount of time they take isn't always static

some of the calls have to do a lot more heavy lifting than others

"Run as many of this as possible without dipping below X framerate" seemed like a common enough use case that I thought UniTask might have a system for doing so other than Stopwatches and Yields

[steady bobcat]

Its probably an over step(for UniTask to provide this) but you can surely make your own utility to run a set of Func<UniTask> and wait till another frame between if some time limit is reached.

[chilly surge]

Are you doing something that must be done on main thread? Because otherwise you could just put everything in a background thread and let it run as long as needed.

[naive swallow]

Yes, lots of Unity functions like AddComponents

[chilly surge]

Yeah I don't think there's something built in, but you could make a method that returns Time.realtimeSinceStartup - Time.unscaledTime > budget ? UniTask.NextFrame() : UniTask.CompletedTask.

[steady bobcat]

I wouldn't do it this way but as I suggested if you wish to avoid placing checks everywhere

[naive swallow]

Basically, I wrapped the expensive-ass function in this:

Stopwatch timer = new Stopwatch();
timer.Start();
long currentTime = 0;
foreach(...){
  long startMills = timer.ElapsedMilliseconds;
  ExpensiveAssFunction();
  long endMills = timer.ElapsedMilliseconds;
  currentTime += (endMills - startMills);

  if (currentTime > 33)
  {
    await UniTask.Yield();
    currentTime = 0;
  }
}

I'll un-magic that number if this works

[chilly surge]

Giving a list of functions is basically just abstracting on top of it, so instead of manually placing checks, you manually split it into multiple functions, it's not much different.

It's actually worse if you need to pass values from one function to the next.

[chilly surge]

Yeah with a method wrapped up like above, you could just do something like:

foreach (...)
{
    // Some expensive work

    await NextFrameIfOver(0.033f);
}

(Well, depends on how you want the budget to be counted)

[night hearth]

Can someone help me in #💻┃code-beginner
I got a Big issue and i cant find the problem 😓

[steady bobcat]

Well they kinda wanted it to be automatic so do you

[chilly surge]

You have to manually decide where is an acceptable place to break into next frame, no matter the approach.

[naive swallow]

That's certainly more automatic than what I have

[chilly surge]

The difference is just "where do I manually insert await NextFrameIfOver(budget)" vs "where do I manually split this function into multiple parts."

[naive swallow]

I hadn't thought of just using unscaledTime as the benchmark... that's a good idea. Lemme give that shot

[rigid island]

don't crosspost next time. Stay in 1 channel

[thick terrace]

one slightly more automatic way i've done this in the past is writing the method in question as a coroutine, then instead of running it directly, make a wrapper method that takes an IEnumerator and iterates through it step by step and waits as necessary between steps. it's not much more automatic than the above, but it means you don't have to actually put any timing specific code in with the real work, just yield return null and let the wrapper method decide what to do, so it's really easy to do things like vary the rate or do other stuff between steps

[hot ledge]

I'm trying to set the color of specific sections of text in a TextMeshProUGUI component using scripts, but I'm struggling to get it working. The most I've been able to do is change the color of the text's underline.

https://codeshare.io/5zEor2

[leaden ice]

You don't need to do anything as drastic as manipulating vertex colors

You can use Rich Text tags: https://docs.unity3d.com/Packages/com.unity.textmeshpro@4.0/manual/RichTextColor.html

[hot ledge]

that's what I resorted to when <color=#FFFF00> didn't work

[leaden ice]

It should work fine 🤔

[hot ledge]

like I said, it only changes the underline

[leaden ice]

maybe an issue with your font or something? 🤔

What if you do it on text that isn't underlined?

does it work then?

[hot ledge]

nothing then

[leaden ice]

What if you switch fonts

[hot ledge]

but, the colors do change if I mess with the vertex color

[hot ledge]

it's gotta be this font, or one very similar

[leaden ice]

Sure but

just for the sake of figuring out the problem

an you try the default font for example

If that also doesn't work then we can at least rule out the font as the issue.

[hot ledge]

issue persists it seems

[leaden ice]

Strange. I've never had an issue with this 🤔

What if you try to change the order of the nesting of the tags?

For example instead of <color><u>text try <u><color>text

[narrow sapphire]

Have you tried 8 characters

[leaden ice]

aalso a good idea^

[narrow sapphire]

That might make sense

[rain minnow]

Be careful with adding. That's a nasty, expensive method . . .

[narrow sapphire]

So you can change the colour of only the underline

[naive swallow]

Yep, that's why I want to run them sequentially instead of all at once, but I can't put them on different threads

[leaden ice]

silly question what if you try this in a separate completely empty scene

Just put a TMP_Text in it alone and play with the font and tags

delete all other objects

Also make sure to look at it in Game View not just scene view

[hot ledge]

oh wait I think I figured it out, Override Tags was enabled

[narrow sapphire]

You didn’t put the color= on this btw

[hot ledge]

it's supposed to work either way I think

yeh there we go

[leaden ice]

Ahh - I forgot about that checkbox

I do think that might be a bug though - the fact that it was coloring only the underline

[hot ledge]

Follow up question:
This text is inside a scroll box, I wanna have it set up so that the box automatically scrolls to the section of the text that's highlighted whenever it's enabled. How would I do that?

would it be possible to grab position values from the vertex index of a character or something similar?

[rain minnow]

Yeah, different threads wouldn't work. Do you have to use AddComponent? Are you able to place the component on the GameObject and enable it?

[naive swallow]

Yes, they're components that need to be there on a fully runtime-initialized gameObject loaded from a mesh in a different directory. Not every component is going to be on every mesh, there's no way around having AddComponents

[narrow sapphire]

Hmm split lines, iterate until you see colour tag then lineheight * line number?

[steady bobcat]

You can get text info about the whole thing and set the relative scroll pos but finding where the text is im not sure 🤔

[hot ledge]

line heights are kinda random cuz of the text wrapping

[narrow sapphire]

No can do then with this setup I think

Not easily at least

Why not make each conversation line separate and spawn them all in when needed

[hot ledge]

because 50 gameobjects being instantiated into a single text box will lag my quest 3 lol

[narrow sapphire]

Then you can reuse the same ones

No need to create and destroy gos yeah ur right tbh

[hot ledge]

I tried that with a different thing in my scene, an ingame debug output view with 100 components

[rain minnow]

Ouch, that seems difficult . . .

[hot ledge]

it was responsible for like half of all of my performance issues lmao

[chilly surge]

Not sure about TMP, but UGUI text has a TextGenerator, you can use that to grab all the positions of characters and lines.

[narrow sapphire]

If performance is that tight that you can’t handle 20 gos for 20 bits of ui text then idk

[hot ledge]

I am using a TextMeshProUGUI component

[narrow sapphire]

Is it necessary to have the entire conversation at once?

[hot ledge]

nope, it's already split into pages

[narrow sapphire]

A solution if it’s ok is to just split up the conversation

More

Important highlighted text could even be its own conversation turn

Makes sense if it’s important

[hot ledge]

with a max line count of 50 I'm already getting 32 pages of text in some places lol

[narrow sapphire]

From a player standpoint it’s a bit of a flash bang to get all this text

At once

More easily engagable if it’s a few lines max at a time

VN style

[hot ledge]

this is less of a game and more of a data science app so the text is the content inherently

[steady bobcat]

I wonder if you use GetTextInfo() and use the character infos it provides? https://docs.unity3d.com/Packages/com.unity.textmeshpro@4.0/api/TMPro.TMP_Text.html#TMPro_TMP_Text_GetTextInfo_System_String_

Not sure if topleft/topright is the character local pos: https://docs.unity3d.com/Packages/com.unity.textmeshpro@4.0/api/TMPro.TMP_CharacterInfo.html#TMPro_TMP_CharacterInfo_topLeft

nothing has a description

[narrow sapphire]

Yes I just saw this on docs while looking through

At same time haha

If you like foreach var wordinfo

Check for the text you need

Then get first character position

Should work

Surprised that exists actually

[steady bobcat]

yea you can loop until you get a match over a range of characters and then use the first to calculate the new scroll pos

[hot ledge]

yeah I think that's working, it seems to be localPos

gotta edit my code's logic a bit to actually get the correct character index but I'll try it

[narrow sapphire]

WordInfo.textcomponent.m_fontColor might be easiest

There’s like a gazillion properties in this TMP_Text class

Ah there’s one that’s just textcomponent.color

[steady bobcat]

If you can insert your own tag and find that then that would be a clean solution
using colour seems bad

yes we know its coloured yellow but its not very reliable vs an exact string match or pre determined char index.

[narrow sapphire]

Lots more effort though

[narrow sapphire]

I wouldn’t be unhappy using color cause it takes 10s with the stipulation of you have to change to this method if you NEED to

Nevermind there is actually textcomponent.string

All the way at the bottom of this 300 entry properties list

[chilly surge]

Not surprised that mesh info is exposed especially since UGUI text also exposes it.

[narrow sapphire]

Though this might not contain the tags

[chilly surge]

I've always wished instead of some weird BBC custom format they use for rich text, they would just expose the internal AST.

[narrow sapphire]

There might not be any way to distinguish without using color or some other actual property of the text

[chilly surge]

Trying to sanitize user content by escaping the BBC tags is hacky and weird, and there are quite a few of Unity games that they just don't bother and you can use BBC tags to change your user name colors and what not.

[steady bobcat]

oh shit you can get link info so you could use this to easily find the character positions for the headings

presuming these can be made to not change the text style

[hot ledge]

hmm.. I can't seem to figure out how to get the right character index

I'm currently doing it by just noting the length of the string one I find the line to highlight

but that apparently doesn't line up with the actual character indices in the textbox

seems like the string length is always longer than the length of the characterInfo array

[steady bobcat]

it surely wont include the tags so the rendered characters len will be less than the input string...

[narrow sapphire]

I think string excludes the tags tho

The scripting docs said ‘string to be displayed’ or something like that

[steady bobcat]

i presumed they were checking the original but you can just loop till you hit a char info matching char 0 of some string and keep going till you get a full match

you just need to know the thing to find such as "foobar"

[hot ledge]

oh wait one of the characterInfo properties is lineNumber

[steady bobcat]

😐 well

Hi!

[steady bone]

Hello everyone, I’ll try to keep it brief.
I’m currently working on a year-end project at my school and I’m using the MultiplayerService for sessions. The problem is that the school’s internet connection is quite slow, so I can’t create sessions and I keep getting timed out (knowing that it works fine at home or using 4G).
I wanted to know if anyone here had any workaround solutions that could help me out? (aside from being on 4G all the time).
Thanks a lot!

[steady bobcat]

Does it let you specify the timeout time?

how bad is the internet, can you check via https://fast.com ?

[steady bone]

It doesn't look so bad at first glance, but the problem doesn't occur all the time, and in the evening when there are fewer people, it works without too much trouble.

My theory is that the client is trying to join the session when it hasn't been created

Since the function is in async

I don't have a lot of knowledge on the subject, so I don't have an overview, if someone can tell me the potential causes of this issues

[narrow sapphire]

I would show ur code in networking channel

From my experience in n4e the designs were such that that isn’t possible

Idk if n4go is much different but I’d assume you’d want the same

Okay, i'm doing it

So basically, when we want to dash horizontally we just press Shift, and if we want to dash upwards we need to press Z, but we just want only one button to dash in every direction, sadly we cant find the solution
Here's the code (2 parts separated) : https://scriptbin.xyz/odixudatac.cs

[vestal arch]

if you aren't using w/s for anything you could use wasd to aim the dash as well

[lament estuary]

Yea we thought about that but we can't seem to find how to really do it like that

[vestal arch]

i mean do you have the dash mechanic itself done?

[narrow sapphire]

Input axes from wasd into a normalised vector

[vestal arch]

you would just dash in the direction specified by wasd

[narrow sapphire]

And check holding space to dash up

[lament estuary]

Okay i'll try to do it like that, and tell you if it works

Thanks

[neon plank]

I have a little math problem and I'm having trouble solving it.
I have a character that must look up a target by rotating its neck (vertical and horizontal rotation). However necks has a limit and so I must to clamp it somehow.
I have this values:

• A Vector3 baseDirection which is the base direction of the head (the "forward" vector).
• A Vector3 targetDirection which is the (unconstrained) direction towards the target.
• A float maxHorizontal which is the maximum number of degrees the head can rotate horizontally.
• A float maxUpward which is the maximum number of degrees the head can rotate upwards.
• A float maxDownward which is the maximum number of degrees the head can rotate downwards.
  And I must to use this in order to get a Vector3 newDirection which is the (constrianed) direction towards the target in which the character won't break its neck .
  But I don't know how to get that.

I was trying with:

Quaternion delta = Quaternion.FromToRotation(baseDirection, targetDirection);
Vector3 angles = delta.eulerAngles;
angles = Normalize(angles); // Convert range to [-180;180]
angles.y = math.clamp(angles.y, -maxUpward, aimingTargetMaximumHorizontalAngle);
angles.x = math.clamp(angles.x, -maxDownward, maxUpward);
Quaternion newDelta = Quaternion.Euler(angles);
Vector3 newDirection = newDelta * baseDirection;

But it doesn't work. I'm not sure how to solve this.

    public void Reposition()
    {
        player.transform.position = repositionObject.transform.position;
    }
}

why is this simple script not working on build but works on development?

[hexed pecan]

Try debugging it in a development build

[steady bobcat]

any runtime errors? im going to guess player becomes null

[young yacht]

fixed

using System.Collections;
using UnityEngine;

public class RepositionPlayer : MonoBehaviour
{
    //where the player should spawn
    [SerializeField] GameObject player;
    [SerializeField] GameObject repositionObject;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    IEnumerator Start()
    {
        yield return null;
        
        player = GameObject.FindGameObjectWithTag("Player");

        Reposition();
    }

    public void Reposition()
    {
        player.transform.position = repositionObject.transform.position;
    }
}

[steady bobcat]

why is player also serialized if you then find it by tag?

Finding by tag is un reliable and you should always prefer serialized fields of the needed component type when possible.
e.g. [SerializeField] Player player;

[young yacht]

this repositionPlayer object is in every scene

its not manually referenced

hence the tag reference

[steady bobcat]

Perhaps a static reference to the player should be preffered then or you can better integrate this into your scene loading logic (e.g load scene, get spawn pos, move player to spawn pos)

Finding by name/tag is fine when a beginner but not a good practice long term

[young yacht]

hm i see

i'll check on static references

thanks!

[young yacht]

what about a C# event?

[steady bobcat]

well if you have the ability to invoke an event and have the player listen then yea do that.
I like to have a component in newly loaded scenes (e.g. for a level) that is used to facilitate initialisation and setup (e.g. has ref to start pos and is directly read and applied to the player in level load logic)

[steady bobcat]

Just make sure you unsub monobehaviour functions from events when they get destroyed to prevent future issues

[young yacht]

so you have a OnLoadManager kinda?

sets up everything nicely on every scene start

[young yacht]

yea i do that already otherwise memory leak goes brr

[steady bobcat]

Games I have worked on recently have a LevelLoadService (not mono) and a LevelInit and LevelController in the level scene. this is found by the service when the scene is loaded.

[young yacht]

hm i might do that in future projects

this is my first proper project so its full of shitty practices

learned about C# events halfway through

[steady bobcat]

events are great. UnityEvent exists also which lets you serialize subscriptions in the inspector (has a cost due to needing reflection to resolve at runtime)

[young yacht]

i tried both but C# events just seem way more intuitive

and having to set up all events manually with UnityEvents just doesnt cut it for me

[steady bobcat]

you can sub in code too but yea a c# event is preferred for code only stuff

Hello I'm working on VR game and encounter problem when I want to attach and detach object to another game object. When I detach game object (grab) the size will be smaller. does anyone know how to solve it?

public class OnCollisionTrash : MonoBehaviour

    public Transform slotObject;
    public GameObject attachedTrash;
    private bool isAttached = false;

    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Trash") && !isAttached)
        {
            // Attach trash to slot
            other.transform.SetParent(slotObject, true);
            other.transform.position = slotObject.position;

            // Optional: Stop movement
            Rigidbody rb = other.GetComponent<Rigidbody>();
            if (rb != null)
            {

[wary ferry]

Is there any built in file picker in unity that isn’t the editor utility one?

[hexed pecan]

Pretty sure you need to use a third party asset/package for that

[wary ferry]

Huh wild I really thought their would be something built in for that

Thanks for the answer!

[steady bobcat]

I presume its not a thing because many platforms just wont have one that works the same as pc/mac/linux.

but in editor they know its gonna be one of 3 platforms so its easier to use the os provided one

[eager yacht]

https://github.com/keiwando/nativefileso
https://github.com/gkngkc/UnityStandaloneFileBrowser
There are options on github

[wary ferry]

This looks great I’ll probably go with using this

[wary ferry]

Hmm I guess that’s fair… but they have lots of other features that have to host separate code for each operating system, I’d hope that they have at least something that tries to work

[delicate flax]

just so you know, there is a bug in that lib during builds (from unity 2023.3+ iirc)
https://github.com/gkngkc/UnityStandaloneFileBrowser/issues/145
the fix is posted in the issues tab on the github

Hi, is anyone familiar with making particle system with collision on? my cubic smoke kept clip through floors, it sometimes work and sometimes don't. I want to do a rocket landing smoke effect.

I did add rigidbody to my terrain tiles. Sometimes the particles worked some times it doesn't like in the video. Two of them worked but other two didn't. There are times that they all worked.

here are my particle collision settings. Not sure more information is needed.

Thanks

I'm trying to use EditorSceneManager.GetSceneByName to get the scene name while in editor. It works for one scene but not another.

I have 2 scenes, PrimaryScene and SecondaryScene.
PrimaryScene works when using that call, but SecondaryScene fails. They're both in the same directory

[somber tapir]

are they both added to the build?

[hexed oak]

yes

index 0 and 1

Though that may change between projects, it's not guaranteed

[steady bobcat]

you can search for the asset by name btw

[hexed oak]

oh my god EditorSceneManager only returns information if the scene is loaded in the hierarchy

that is so stupid, the whole point of using it is to get the scene name so I can load it into the hierarchy

[steady bobcat]

so search for the asset and load it then with the editor scene manager

AssetDatabase.FindAssets("t:Scene MyCoolScene");

[hexed oak]

yeah that's gonna have to be how I do it

[wild elbow]

Are script-only stack traces supposed to work when logging in non-development builds? Up until recently I swear they did and were just missing line numbers. But now it's just the log message and no stack. I don't see any relevant changes in our project's code or packages, I've looked at all the build and player settings, I'm checking Application.Get/SetStackTraceLogType() at runtime. And it all looks fine. If I turn on full stacks, it works, but script-only just fails. What am I doing wrong? (Unity 2022.3.42f1, mono scripting back end, Windows build)

[steady bobcat]

Is this for managed exceptions or for crashes?

[neat tundra]

so I'm really not sure what the heck is going on

[wild elbow]

it's for all uses of the Debug.Log* API

[hexed oak]

As it turns out, in other projects, I have scenes that are named PrimaryScene1, SecondaryScene3, SecondaryScene4, etc.

I have the correct name of the scene that I need defined in a scriptable object, but using AssetDatabase.FindAssets($"t:Scene {mySceneName}"); causes it to return the wrong scene--basically a total crapshoot if it finds the one I want or not.

[steady bobcat]

well its gonna return all matches for the search so i guess its then up to you to find the correct one?

[hexed oak]

yeah actually, I'll just iterate them to match the string name I have. FindAssets returns an array of guids. Gotta get the actual asset

[steady bobcat]

yea you can convert guid to asset path and then load with this

[hexed oak]

yep, got it working! Thank you!

[gilded jackal]

Hi im having issues here but the scenes are in the build settings?

[steady bobcat]

LoadingScreen != LoadingScene
names dont match 🙂

[gilded jackal]

now im asking this because ive been staring at these too long and my brains scrambled can u see which one is missmatches

[steady bobcat]

the error states the scene name you used and this doesn't match any of the ones in the build settings list

[gilded jackal]

but here are them together

U see there both titled LoadingScene

[steady bobcat]

read it again and think 😐

[fiery steeple]

Hey, I have these areas that I need the player and NPCs to be at certain time and if they're not in those areas at certain time they will receive a strike and after 3 strikes they're punished. So what's the proper way to communicate from the script that's on those areas (Box Collider with "Trigger" set to true) to the DailyRoutineManager that handles all aspect of checking if they were in those areas at the right time, punishing them, etc... ?

right now I have this :

• DayNightCycle.cs handles the DayNight timer of 24 hours and it has an Action called OnGameTimeChanged that's called everytime the time changes
• DailyRoutineManager.cs that subscribes to OnGameTimeChanged to do all the checking about the players and NPCs
• OnAreaEnter.cs that's on those BoxCollision ( Trigger) that detects when those players or NPCS enter those overlap box

So I need to connect them in some way to make all this system work

[rigid island]

make an event that when a certain player enters / exits an area it stores it in some type of collection, then when OnGameTimeChanged and you need to check if they are in that certain spot in collection, if they are not then you punish those not in that collection

[slim pelican]

what is the best way to implement anti corner-snagging? I've tried using a (yellow) vertical raycast in front of the player (slightly behind the actual horizontal raycasts) and it works surprisingly well but I was wondering if this is a known method that has any downsides to it, or if theres a much better method

(also please ignore the blue raycasts, those arent the horiziontal collision raycasts)

[trim schooner]

Their names are literally in the errors

[near granite]

Yea I tried

[naive swallow]

Basically the best way to make any sort of character controller is to make them look like Pinhead with all the raycasts coming out of them at all times. In general, people don't do enough raycasts when making a character controller

[leaden ice]

you could also do a boxcast

[slim pelican]

I considered that and it did work well but it took around 40 raycasts to stop any noticeable snagging and jittering. Isnt that dar too many?

[slim pelican]

It's kinematic rigidbody so I need to know the direction to halt movement

[naive swallow]

*Kylo Ren meme*
MORE!

[slim pelican]

Actually? Idk if that's bad practice or not to just spam raycasts even if I can afford to do so

[naive swallow]

It's partially a joke, but also don't be afraid to just spam raycasts everywhere, they're incredibly cheap

[novel cypress]

Hello, I would like to know th best practice to manage multiple managers. For example, let's say I have Level Manager, Inventory Manager and Game Manager in my Level scene. When the player will go back to the Menu scene, all these Managers will be useless, and they could even break the game since some references (like player for example) won't be found. So, what is the best way to tell which managers I need and in which scenes ?

[naive swallow]

Best way is to ensure one-way data access to the managers, and the managers don't reference any specific objects in the scene that might not be there. That way, them being around in scenes they're not needed in is no big deal - things just won't actually be referencing them

the way id do it is have a generic "file" interface that supports being opened/closed or whatever you'd need, then have each unique file type implement it's own behavior, but that's having never really used SOs

boxcast gives you that

[slim pelican]

Does it? I thought the data only told you if it collided with something and not the side it came from

Interesting.

[leaden ice]

you're probably confusing OverlapBox or CheckBox with BoxCast

[slim pelican]

Why do some people prefer doing simple raycasts over using a boxcast sometimes then if it does the job better (seemingly)

[leaden ice]

different tools for different purposes

if you want to cast a ray through the scene, use raycast
If you want to cast a box through the scene, use boxcast

[slim pelican]

Sorry I meant specifically for collisions

[leaden ice]

what about them

[slim pelican]

I've seen many people use simple line raycasts for kinematic collision detection so I'm unsure why they'd chose to do that over a boxocast

[leaden ice]

Probably because they don't know any better

[slim pelican]

Fair enough lol

[leaden ice]

I'd say most of the time it's a capsule shaped character and CapsuleCast.

[slim pelican]

I've done all of my collisions and movement features (auto stepping) with raycasts on a boxcollider 😭

Works fine except when walking into vertices or walking along a vertex (the player bobs up and down because the corner can go between the vertical collision raycasts

[fiery steeple]

Hey,
are there advantages / drawbacks to use tag over component / script + TryGetComponent() and vice versa please ?

[vestal arch]

using tags you need magic strings

[fiery steeple]

magic strings ?

[vestal arch]

if you're using this for static references, you should use serialized references instead

[fiery steeple]

I'm not sure to understand what this means 🤔

[vestal arch]

specific strings as identifiers, if you typo the string it breaks

[vestal arch]

if you want to just get the player or camera or whatever statically, you could set them in the inspector instead

[fiery steeple]

but in the IDE if you use CompareTag, it suggests you all the existing tags so you don't have to type them by hand

[vestal arch]

that doesn't change the fact that they're magic strings though

if you rename a tag it also breaks

[fiery steeple]

oh yeah, so it's better to use Components and TryGetComponent<>() ?

[somber nacelle]

it suggests you all the existing tags so you don't have to type them by hand
pretty sure that's a rider-only thing and the vs and vs code definitely don't do that

[fiery steeple]

Oh yeah I'm using Rider

[somber nacelle]

lol yeah i could tell based on the fact that you have tags in your intellisense

[vestal arch]

it's better to used serialized references if possible

but tags aren't really comparable to getcomponent calls anyways, so not sure what you're really asking

[somber nacelle]

if the options are compare tag vs trygetcomponent it sounds like this is likely for collisions rather than having direct references

[vestal arch]

tags give you gameobjects, getcomponent gives you components

[fiery steeple]

Can't always do that. Here for instance I have an area that I need to check what entered it and if it's a Player or an NPC execute some code, so I could give both the same tag but it doesn't look like the best way as if I need those to have other tags I can't do that anymore, so that's why I thought about giving them a script component called "Entity" and check the thing entering the area if it has that script.

[somber nacelle]

but TryGetComponent is typically going to be better if you're going to need to get the component. if you're not then a CompareTag is just fine and you can make it ever so slightly better by using a TagHandle rather than passing the string directly to the method

[fiery steeple]

I'm asking because I'm facing that problem in my last message☝️

[fiery steeple]

Yes because I need to check an ID on the thing entering that trigger box, if it's a player or one of the NPCs, I need to save those in a list

[steady bobcat]

then i guess you get the component and read the id from that

[shell scarab]

Hey, can anyone help with displaying an animation for a calculated random outcome? Doesn’t have to be an actual animation, could be animated with code.

For example a dice roll, it would be calculated but then needs to be animated to show the dice land on that number.

Or another example spin the wheel type thing, where the number chosen is calculated but it needs to land on the right number visually.

Km not sure where to start with this, and i cant find anything at all through googling, although im not sure exactly what to google for this.

[cosmic rain]

This is quite difficult to implement and most games just fake it.

[shell scarab]

not sure how it’s faked

[cosmic rain]

There could be many ways. For example, with the dices, there could be only one or several animations, and they know what side they would end up falling on, so they set the initial rotation or the assigned textures such that the desired outcome is displayed.

[cold parrot]

make up a random dice roll simulation so you know the outcome, put values on the sides that you want, run it again with the numbers

[shell scarab]

im still not exactly sure how this helps and i feel its missing a ton of context. Can you explain in what way this dice roll effect would be shown to the player? And i think this quickly gets more complicated if there are multiple dice.

[night harness]

if the random outcome is calculated, generally displaying said outcome is "calculated". a majority of games do not pre-calculate random outcomes then dynamically handle displaying them (in this case the physics of a dice rolling)

[cosmic rain]

Let's say an animation always ends up showning side A on top in the end. Then before starting the animation, they calculate the random result(1-6 for example), and set side A to have that result. Then run the animation

[shell scarab]

So for a set of 4 dice i’d have 1,296 animations?

that doesnt seem practical

[cosmic rain]

No. You only need 1 animation

[night harness]

no you'd have 6 animations that can be played on 1 dice 4 times

[cosmic rain]

You seem to be missing the point

[shell scarab]

Oh okay, this actually just gave me the point!!

I see what you’re saying now

One animation, and just place the faces on the sides so that the one you want ends up on top

Is that what you’re saying?

[cosmic rain]

Yes

is there any way in unity to make [CallerFilePath] use relative paths instead of absolute? I know how to do that in .NET but I have no idea how to do that in unity

[last raven]

I found a way by adding -pathmap:PATH=. but now I have the problem that I have to hardcode PATH, I don't know how to use environment/project variables in csc.rsp file

I tried -pathmap:$(MSBuildThisFileDirectory)=. and -pathmap:$(SolutionDir)=. but neither work

is it possible to add C# compiler options in editor scripts before build?

[vapid swift]

hi

Can someone tell me why despite having using Unity.Services.Multiplayer; in my code

Lobby can't be resolved?

Assets\Scripts\MainMenuHandler.cs(10,13): error CS0246: The type or namespace name 'Lobby' could not be found (are you missing a using directive or an assembly reference?)

thanks in advance

[last raven]

because using only dumps names in the namespace into file global scope so you don't have to type fully qualified name but it does not actually add any references to project/assembly/package

make sure that package containing that class is actually added to project

[vapid swift]

yeah

[vapid swift]

I think I did

I mean I installed it from the Package Manager

[last raven]

look if you need to maybe add assembly reference manually with -r:assemblyname parameter csc.rsp file or into asmdef file if your code is in the library

[vapid swift]

i don't even know what this assembly stuff is 😭

[night harness]

is that class even in that package

can you link the api reference for it

[vapid swift]

it hould be

https://docs.unity.com/ugs/en-us/manual/lobby/manual/unity-lobby-service

[night harness]

what version of unity are you on

[vapid swift]

6.0

i dont have any asmdef files

[somber nacelle]

Does that package even include a type called Lobby?

[vapid swift]

From what I know it should

[somber nacelle]

Hint: look in the documentation

[last raven]

you don't but packages usually have, but unity ones should all be set to "auto referenced" so you don't have to do anything else usually and yes, you're right, based on documentation it should have Lobby class but it's in the Unity.Services.Lobbies.Models

[vapid swift]

Well I don't really understand the documentation

Which is why I'm asking here

[last raven]

https://docs.unity3d.com/Packages/com.unity.services.multiplayer@1.1/api/Unity.Services.Lobbies.Models.Lobby.html?q=Lobby

[vapid swift]

it says "Lobby" is in the Multiplayer Services SDK

[last raven]

doc is pretty garbage like all unity docs

[somber nacelle]

Is your IDE configured so you see red underlines for errors in your code?

[last raven]

so try using Unity.Services.Lobbies.Models.Lobby instead

[vapid swift]

thank you very much, I'll try that

[somber nacelle]

Instead, since the namespaces have been changed in the latest version, they should use the quick actions in their IDE to add the correct namespace

[vapid swift]

I got the C# and Unity Extensions for VSCode, nothing is turning red when somethings wrong

[last raven]

it should work

you might need to configure it

I use it and it works for me

[vapid swift]

damn

[somber nacelle]

https://unity.huh.how/ide-configuration/visual-studio-code

[last raven]

make sure unity also has VSCode extension, VSCode is selected as editor and you use "regenerate .csproj"

that might help

[vapid swift]

well now im getting totally different errors

but that should be due to the Lobby finally getting recognized

thank you very much guys! 🙂

[last raven]

if you correctly configure VSCode you can fix that with Ctrl+. on these classes

also if you want to use C# 10 in unity you can also do that

[somber nacelle]

for future reference for everyone here:

[last raven]

is it possible to use environment variables in csc.rsp file?

[vague cosmos]

Hi there, i was experimenting with using input system to make a local multiplayer game, but using the player input component and player input manager, i can only join with the keyboard, and my controller (Xbox series controller) does not work. I checked in the input debugger, and the controller is being detected, so i'm kinda at a loss

Here are the related screenshots

[leaden ice]

likely control scheme related

[quick elbow]

Why use IL2CPP vs. Mono? I see that generally IL2CPP offers better performance. I imagine that is still true since it's AOT compilation. However, I also see IL2CPP can introduce a lot of weird errors

[leaden ice]

• Better Performance
• It's available on more target platforms than Mono

[quick elbow]

Thanks. I have used IL2CPP in the past because my previous projects required it for the platform we were targeting. Working on a different project for PC now so contemplating Mono vs. IL2CPP. I remember we had a lot of weird issues with IL2CPP

[leaden ice]

I find that IL2CPP issues are quire rare and usually isolated to reflection-based stuff.

[quick elbow]

Good to know. My prior projects were for Universal Windows Platform... which doesn't really get much support. So I imagine that was a part of our problem

[leaden ice]

probably yes

[tepid shore]

somehow this script makes my fps go from over 280 to barely 90

[violet nymph]

Use the profiler because it's not likely to do that unless you have a billion of them running (over exaggeration, but you get the point)

[tepid shore]

the lag was due to the Vector3 being a public and showing in the editor

probably some wierd issue with the unity editor playmode

[violet nymph]

Serialization causing lag is weird

[tepid shore]

yeah

turning it to private fixed the issue

[south summit]

is there a #support here? Because i need some help

[young tapir]

With?

[vestal arch]

they're all help channels #🔎┃find-a-channel

why are you using unity 2017 lol

[violet nymph]

Should ask in #💻┃unity-talk as I don't think that there's a channel for that

Definitely not code related

[south summit]

Making a Wii U game, and it needs that specific reason

[south summit]

Ok, will ask in there

[cold parrot]

old U version, unsupported target platform, issues getting stuff to run --> red flags, likely some things invovled that we don't talk about here

[steady bobcat]

Remember that person who was using unity 5

Best to keep up with the oldest version with support which is 2022 rn (2021 I think has extended pro support)

[vapid swift]

Can someone tell me what it means if you get this error, despite having set all dependencies (dragging the Button Component into the Button Field of the Canvas > MainMenuHandler Script in this case) ?

Initialization error: Object reference not set to an instance of an object
UnityEngine.Debug:LogError (object)
MainMenuHandler/<Start>d__7:MoveNext () (at Assets/Scripts/MainMenuHandler.cs:84)
System.Runtime.CompilerServices.AsyncVoidMethodBuilder:Start<MainMenuHandler/<Start>d__7> (MainMenuHandler/<Start>d__7&)
MainMenuHandler:Start ()

[vestal arch]

well, check what's on MainMenuHandler line 84

perhaps something was unassigned at runtime

[vapid swift]

Debug.LogError("Initialization error: " + e.Message);

[vestal arch]

or maybe you're looking at the wrong component

[vestal arch]

oh you're logging that manually, rather than having it throw itself?

[vapid swift]

I just catch an exception there and log that

here's what I do that throws the error:
playButton.interactable = true;

I just access the button and set interactable to true

[vestal arch]

add gameObject to the log as the second argument, so you can see which object it's logging from

it might not be the one you're looking at in the inspector

[vapid swift]

ohh okay

[dense rock]

I have some weird problem where I use

Destroy(gameObject, 5f);
```Now if the 5s aren't up when I exit the play mode, the object is apparently saved in the scene. Is there a reason for that? context might be important, it's instantiated as child of a dontDestroyOnLoad object

[vapid swift]

Initialization error: Object reference not set to an instance of an object
UnityEngine.Debug:LogError (object,UnityEngine.Object)
MainMenuHandler/<Start>d__7:MoveNext () (at Assets/Scripts/MainMenuHandler.cs:84)
System.Runtime.CompilerServices.AsyncVoidMethodBuilder:Start<MainMenuHandler/<Start>d__7> (MainMenuHandler/<Start>d__7&)
MainMenuHandler:Start ()

Now it logs this

the exact same as before???

[vestal arch]

click (or double click? i forget) the error to highlight what object it's from

[vapid swift]

yeah

it's Canvas as I thought

[civic girder]

In a game where the UI is part of the gameplay (like pokemon, FF, etc).

What type of class is responsible for controlling the UI?

Like would the battle system be calling the UIManager?
Or the turn system calling the UI?
Or others?

[vestal arch]

are you sure it's this line

[latent latch]

CombatManager with CombatUIManager
Usually the idea is the UI invokes events it has subscribed on the CombatManager, but if you don't care too much for that I'd just reference it directly.

[vapid swift]

no

XD

try
        {
            await AuthManager.Instance.InitializeAsync();
            isInitialized = true;

            // Slight delay to ensure UI updates
            await Task.Delay(100);

            playButton.interactable = true; // Enable the Play button after initialization
            if (statusText != null) statusText.text = "Ready! Click Play to join.";
        }
        catch (System.Exception e)
        {
            if (statusText != null) statusText.text = "Initialization failed: " + e.Message;
            Debug.LogError("Initialization error: " + e.Message, gameObject);
        }

that's the entire try catch block

[vestal arch]

try narrowing it down then

or could just comment out the try/catch bits so it points to where the error actually comes from

[vapid swift]

yeah so i let it log itself

just throw the exception

I'll try that

ohhhh

now it makes more sense

NullReferenceException: Object reference not set to an instance of an object
MainMenuHandler.Start () (at Assets/Scripts/MainMenuHandler.cs:72)
System.Runtime.CompilerServices.AsyncMethodBuilderCore+<>c.<ThrowAsync>b__7_0 (System.Object state) (at <314938d17f3848e8ac683e11b27f62ee>:0)

Line 72: await AuthManager.Instance.InitializeAsync();

[civic girder]

So if I understand correctly, supposing I'd want to show different stuff.

Like turn number or damage dealt or possible moves or confirmation for a move (like "are you sure you want to evolve this unit?")

The CombatManager is responsible for listening to all these events and preparing the relevant data for the CombatUIManager, right?

[vestal arch]

yeah that was the other thing it couldve been, i was suspecting that lol

[latent latch]

The CombatManager does not need to know about a UI at all basically, and usually for decoupling reasons you'd have some event system where the UI would subscribe to so it bridges it between it and the CombatManager, but we're talking about the most proper case here but in reality I've dont have time for that.

So, if you do want callbacks from the CombatManager, a bi-directional reference can suffice

[civic girder]

Yeah I meant as events.
I just mean like: instead of each action doing an event that the UIManager listens to (which may cause different events to interfere or make it hard to track down references),
Would the combatManager act as a proxy that processes the events then raises the appropriate UI events? Or did I misunderstand?

[latent latch]

UIManager -> Invokes event for what the user has selected -> delegates to a method inside of CombatManager (for example the player pressed Attack)
UIManager however may also need callbacks for say stuff like updating statistics like health and game state related information, so it'll also have to subscribe to those methods on the CombatManager.

This would require some reference to bind those events, but otherwise you can also make a event bus that acts as the inbetween (proxy)

[brisk axle]

https://gist.github.com/nehalist/d56b93150e980a5adff418c2b49e5df3

[wicked scroll]

put each ability in its own file and add the AssetMenuAttribute there, otherwise how does it know which one to create? then you need to actually create an instance of that

[brisk axle]

everything is in one file, it was just easier to create the gist this way 🙂

if creating an instance of these abilities is the only way to achieve that; is there an alterantive? having multiple Dashes seems counter productive

[wicked scroll]

you would only create one

there's lots of alternatives

[brisk axle]

okay, let's ask differently: would this approach be any kind of bad practice?

[wicked scroll]

not necessarily, plenty of folks go that route

like anything, it depends on what you're trying to accomplish

[brisk axle]

since a lot of ppl talk about scriptable objects as data containers it seems a bit weird since I'd like to implement the logic of how an ability works also in that class

would that be possible or even wrong?

[brisk axle]

simply put: an ability system that can dynamically add/remove abilities, where abilities (like dash, shoot, etc.) implement the logic of how they work

[wicked scroll]

it can work, you just end up having to pass a lot of things into those method calls or some kind of larger context

[wicked scroll]

sure but that's just 'I want to be able to implement anything in my video game completely abstractly' which is not really anything

[brisk axle]

true 🤷‍♂️ 😄

[wicked scroll]

this architecture is essentially commands/actions with some weird indirection in exchange for being easily editor configurable

whether that tradeoff is worth it will be up to you

[brisk axle]

ok thanks

[steady moat]

Instead, you should use ScriptableObject as "Factory". By example,

public abstract class AbilityDefinition : ScriptableObject {
    public abstract Ability Instantiate();
}

public class FireballAbilityDefinition : AbilityDefinition {
    public override Ability Instantiate()
    {
        return new FireballAbility();
    };
}

[astral sky]

I'm getting hundreds of these messages about the font and they're flooding my logs making them unreadable
I have "Include Font Data" toggled, I do not understand

[vestal arch]

this is a code channel, try #🖼️┃2d-tools, #📲┃ui-ux, or #💻┃unity-talk

[steady moat]

You can add [TAG] into your owns log if you are simply attempting to see your own log and are not interested in fixing the issues. Also, you can use the Collapse option such that error that repeats are all under the same log.

[astral sky]

Collapse helps in the editor but not in the player.log

[steady moat]

If you are inspecting the log manually, you can use a tool to do a search and replace.

Notepad++ and regex can probably works.

[astral sky]

I really don't want to be replacing 900k of lines every time I run the test runner

actually 16k, but point stands, I want to fix this, not ignore it

[sonic trench]

In basic terms,

oops wait

In basic terms,
If I have a rigidbody2D, and on the Update() function i have an 'if (Input.GetKeyDown(x))' {PerformJump()},
is there a way to call the function only on the next FixedUpdate() frame? is it worth the effort?

[vestal arch]

is there a way to call the function only on the next FixedUpdate() frame?
yes
is it worth the effort?
depends on how you're jumping, i guess?
if you're just doing an impulse-type addforce, then, no, you can do that whenever. it doesn't need to be in fixedupdate

[sonic trench]

Just realized I didn't explain what the function does, but yeah, it adds an impulse of force.

[vestal arch]

i mean, "performjump" is pretty self-explanatory

but if there's more stuff that does rely on being on fixedupdate, then it's not too hard to do

just queue it up and consume that in the fixedupdate

[sonic trench]

So if I wanted to do a timed-jump mechanic, like with short jumps and high jumps based on the time holding the key, should that be done in fixed update?

[vestal arch]

could be a bool if it should only be called once, could be an int if it could be called multiple times (if the key was pressed multiple times in that 0.02s gap), could be a list/queue of actions to handle multiple functions with the same behavior

[vestal arch]

should what be done in fixed update?

[sonic trench]

Nvm I can work through it myself lol

Making it too complicated in my head

[vestal arch]

there's a lot of ways to do that system, it might be split up over update/fixedupdate

[sonic trench]

yeah, for my needs I've mostly been sticking to fixed update, Its just GetKeyDown thats been giving me trouble

doesn't seem unreasonable for unity to be able to queue something like that internally, but I'm using a dated version anyway lmao

[vestal arch]

input is frame-bound, they update on frames only

GetKeyDown is true for the 1 frame it was pressed on
if FixedUpdate happens to miss that frame, too bad

it's just not logically correct

[somber wyvern]

HI! I am trying to import a shared library I have written into unity, but I am having some trouble. On import, I get the following error:

"TypeCache is unable to load info on field .FindServerForPlayerResponse::<FoundServer>k__BackingField. Are you missing a reference?"

Basically saying that its having trouble with a backing field for one of the values. However, the way that I have the shared lib written shouldnt really have any issues, the field it refers to is just a bool, and when I try to remove it, it just says that the issue was found with the next variable I had defined there, so I am just assuming its an overall issue with the DLL, which googling seems to conform

The library is only a few files that have response/request packet data, an example is as follows:

using Network.Attributes;
using Network.Packets;

[PacketRequest(typeof(FindServerForPlayerRequest))]
public class FindServerForPlayerResponse : ResponsePacket
{
    public FindServerForPlayerResponse(bool foundServer, int serverId, string name, string publicIpAddress, int port, FindServerForPlayerRequest request) : base(request)
    {
        FoundServer = foundServer;
        ServerId = serverId;
        Name = name;
        PublicIpAddress = publicIpAddress;
        Port = port;
    }

    public bool FoundServer { get; set; } = false;
    public int ServerId { get; set; } = 0;
    public string Name { get; set; } = "";
    public string PublicIpAddress { get; set; } = "";
    public int Port { get; set; } = 0;
}

Ive tried changing the framework it targets, ive tried changing unity to target the .net framwork or .net core in the player settings but nothing clicks

If anyone has dealt with a similar issue, please let me know if you know how to solve this sort of thing

[leaden ice]

Is anything referencing this class? Maybe it's getting stripped or something

[somber wyvern]

Yes I have a few other projectrs that reference the project in my solution and use the class

It compiles and works just fine in the normal vs/C# context but just has trouble when brought into unity

[somber wyvern]

Update: Found it! I needed to manually type that the target was dotnet standard 2.1 in the actual csproj file and unity finally accepted it

Thanks for help regardless :D

[sonic trench]

I know this isnt really a unity (or even coding) question, but is there a way to turn off these spaces in visual studio?

Yes, you will probably find something on google pretty quickly.

[fast glade]

found some really confusing and inconsistent code, i set a class in my mono behaviour that's supposed to be null at the start of the game(which i supposedly achieve by putting class = null at the start function). But for some reason it doesnt work sometimes

[steady bobcat]

if the field has no value by default and is not serializable, it will remain null. Share the code

[fast glade]

isnt there a format for sharing code? i forgot how to do that

[naive swallow]

A class can't be null. A variable that holds an instance of a class can be null. A reference variable is null until you set it.

[steady bobcat]

i presume they meant a field but tru

[fast glade]

sorry, i did mean an instance of a class. It keeps reapearring as new instance instead of staying null until my code replaces it

also would putting [NonSerialized] help my case?

[steady bobcat]

yes but share the code...

[naive swallow]

A variable doesn't just stop being null without your code setting it to something

[fast glade]

yep that's what ive been trying to figure out, but for now atleast i managed to solve the problem by just putting the nonserialized attribute before the class instance

[steady bobcat]

what was the field type then?

[fast glade]

it was [HideInInspector] before

i did some research

[steady bobcat]

yea that doesn't stop serialization

[fast glade]

and with the HII attribute it just gives it a default value anyways :p

while nonserialized automatically sets it as a null from the beginning

[steady bobcat]

yea any serialized field gets given a value (e.g a List will not be null as unity will give it a value)

[fast glade]

what im confused about now is how it didnt turn null when i literally wrote "classInstance = null" at the start function

[steady bobcat]

what i dont understand is WHAT IS THE TYPE

[fast glade]

class type? a custom one

and the class type is serializable so that i could other instances of it on the inspector

[steady bobcat]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/SerializeReference.html

without using this, a class field cannot store null via unity serialization

[fast glade]

thx 😭

[steady bobcat]

I presume the inspector overrode the value to not be null due to it being SerializeField

in a build it should act differently

Otherwise use a custom inspector to draw this information

[fast glade]

ye i think that by putting serializable on the class itself, all instances are all bound the not be null

[steady bobcat]

no its due to this quirk with unity serialization and only this situation shows this behaviour
anywhere else the class acts like we expect

[fast glade]

dang, I gotta read that documentation on how serialization works and shit

[steady bobcat]

the serialize ref doc page explains how it allows storing sub types and null

[fast glade]

ty for that again

[steady bobcat]

from the page:

// This field must use serialize reference so that serialization can store
        // a reference to another Node object, or null.  By-value
        // can never properly represent this sort of self-referencing structure.
        [SerializeReference]
        public Node m_Next = null;

[woeful hamlet]

I'm making a rotating tiles puzzle, as in, there's a grid of stationary square tiles (GameObjects, not Tilemap tiles) depicting various pipe segments, and you have to click and rotate all of them to make the pipes connect from one side to the other.

The visual part was easy, but now I'm wondering if my idea for checking the connections is too complicated because I'm missing some convenient Unity feature.
My thought is for each Tile to have a list of Directions (as an Enum) its pipes are pointing, and references to its neighbours, so whenever it rotates, it can poll its neighbours which Directions they're pointing, and there's a left/right or up/down match between them, save that Direction(s) in a 'connection' list, then tell all its neighbours to update.
And when checking the connection (at the end, not dynamically on every update), I'd start from the entrance tile and recursively find its furthest connection by asking all neighbours for their furthest connection, until I get back a bunch of Null for dead ends, or the exit tile.
I'm aware this description is kinda rough and inaccurate, but it's not about the implementation yet, but the general idea. Am I missing some Unity/C# feature that would make a lot of that work redundant, or am I generally on the right track?

[unkempt meadow]

Guys, is there anything better than a character controller if I don't want all the forces from a rigidbody?

I don't trust my own hardcoded collision. Is there really not anything else?

[steady bobcat]

If you have a grid of tiles and know their directions you can walk from the start to end to check if the path is complete. There are many famous algorithms that can do pathfinding such as A* or Dijkstra's algorithm

[vestal arch]

wdym "all the forces"?

you can disable gravity and linear damping if you want

[unkempt meadow]

I meant if I used a rigidbody instead

[vestal arch]

yeah what do you mean by "all the forces"

you can disable the built-in forces and you could just not AddForce if you don't want to

what's the issue with a rigidbody

[unkempt meadow]

it just jumps around and jitters

it fucks around a lot

which a char controller doesn't do

but char controller has some limitations that make it unviable to me

and with a kinematic rb without gravity, I thought moverotation would check collisions while rotating but it doesn't

[vestal arch]

are you controlling the transform

or what

[unkempt meadow]

wym

yea?

[vestal arch]

then you're using it wrong yeah

[unkempt meadow]

oh no sorry

[vestal arch]

rigidbody controls transform

[unkempt meadow]

no I used moverotation

move position sorry

or the other one
