should I use StreamReader for LoadData aswell?

[soft shard]

Hmm, not completely sure how you could do it through a Editor script, maybe this could help: https://discussions.unity.com/t/how-to-save-screenshot-of-editor-window/485328/3 - it sounds like the idea is to create a new Texture2D during the Repaint phase of the Editor window

[simple egret]

Better be consistent, if you use the same IO methods on both sides, the code is easier to understand

[errant flame]

yea i guess it so but the real problem is i guess when u take screen shot from game view u can dynamicly change size of the gameview and u can route that pixel data to renderTexture etc therefor we can take a hight res textures with api but in editor size there is not because the size of editor rect is stable and fixed idk how can i do that but i will try xd

[merry stream]

what is the difference between ObjectPool.Dispose/Clear? cant find any documentation on it. Also, does anyone know what could be causing a null reference exception when clearing an object pool during a scene change?

[somber nacelle]

there is literally no difference as Dispose just calls Clear. that exception means that something in the pool was likely actually destroyed rather than just being released to the pool

source for my first claim: https://github.com/Unity-Technologies/UnityCsReference/blob/73c16d00a4c84d96ee9e097f5e289371a92133d3/Runtime/Export/ObjectPool/ObjectPools.cs#L160

[merry stream]

okay, but I am trying to Destroy everything in the pool as well

not just release it

is that not what Clear does?

[somber nacelle]

my point is that you destroyed something that is in the object pool prior to calling Clear

[merry stream]

i see

[somber nacelle]

one way this could happen is if your objectpool is stored on a DDOL object but the pooled objects are not and you switch scenes. naturally everything that isn't DDOL will be destroyed

[merry stream]

yes that's exactly what's happening

so do I just not bother with clearing it?

[somber nacelle]

why not clear it before you switch scenes?

or just create a new objectpool instance so the old one gets GC'd

[merry stream]

well it's subscribed to SceneManager.sceneLoaded

so not sure the order

I will do that

[somber nacelle]

sceneLoaded is called when the new scene is loaded, so naturally that happens after the old scene is unloaded and all of its non-DDOL objects are destroyed

[merry stream]

got it

[wintry jackal]

Hi there!
I had some code that changed a sprite alpha. It worked all right.
But I created some animations for this gameobject that change the color of the sprite.
This animations are not played at the same time that the code changes the color.
But i'm guessing once you tweak the color of the sprite renderer from an animation, you cannot change it through code anymore (the same happens if you change the scale through animations and code, the code tops working)

Can anyone tell me if this is right? Also, is there any way to avoid it?

[somber nacelle]

that is correct. you can avoid this by controlling the sprite renderer's color in only one place rather than on both the animator and in code

[merry stream]

if an object gets destroyed from loading a new scene, is it removed from the object pool as well?

or do I NEED to make a new instance to remove all the null references

[somber nacelle]

no, why would it be? the object pool has no knowledge of scene loading

[wintry jackal]

haha i hate this way to avoid my problem. I want to use both T . T
Thanks for your answer ❤️

[twin yoke]

do I have to reset the dynamic font asset when the game is closed?

[dense yoke]

    {
        MoveDirection = Orientation.forward * VerticalInput + Orientation.right * HorizontalInput;

        if(OnSlope())
        {
            rb.AddForce(GetSlopeMoveDirection() * MoveSpeed * 20f, ForceMode.Force);
        }

        if (Grounded)
        {
            rb.AddForce(MoveDirection.normalized * MoveSpeed * 10f, ForceMode.Force);
        }
        else
        {
            rb.AddForce(MoveDirection.normalized * MoveSpeed * 10f * AirMultiplier, ForceMode.Force);
        }
    }```why does it stop very abruptly when i touch a wall while i'm pressing a,w?

[hexed pecan]

What are you expecting to happen? Wallrun?

[dense yoke]

no

[hexed pecan]

Are you going to elaborate? Lol

You aren't expecting to either wallrun (keep moving along the wall) or stop abruptly, so what do you need instead?

[dense yoke]

I don't want to do Wall Run, I just want it to run and walk, but I don't know why when I touch a wall when I press a, w or d, w it stops abruptly as if there was a wall in front of me.

[hexed pecan]

First I'd try creating a PhysicMaterial with low friction. Maybe set dynamic friction to 0

Then assign that to the rigidbody

And maybe set friction combine to min

[dense yoke]

Ok I'll try that, thanks

[merry stream]

at what point would you guys suggest implementing a dependency injection system? is it bad practice to hold some references (root gameobjects for enemies, loot, etc) on a gamemanager?

[rigid island]

unity doesnt really have a proper dependency injection system, you can make a basic one or use libraries. Basic ones including using methods or events to pass around the ref, good to make bootstrapper scenes with ddols etc

[frosty coral]

how do i fix this

[rigid island]

whats Horizonal

[frosty coral]

left to right

[somber nacelle]

Either spell the axis name correctly or set that one up in the settings like the error message says

[frosty coral]

spelt it wrong mb

[merry stream]

yeah i have a bootstrapper scene but im trying to find a better way to get references for the ddols in further scenes. right now im just using FindObjectOfType etc but I don't like it

[rigid island]

if its ddol just make it a singleton and use that

[merry stream]

wdym

[rigid island]

in your ddol, you didn't make singleton ?
maybe use that instead of FindObject

[merry stream]

no no thats not what i mean

im saying getting references FOR the singletons

the player, root gameobjects to spawn enemies, etc

[rigid island]

ohh I mean if its a singleton just access the instance

there are some objects where i use an event tied to ActiveScene changed or SceneLoaded to pass reference through delegate

[merry stream]

i think youre misunderstanding. for example I have my enemy object pool. It needs a reference to a empty gameobject to parent the enemies to. Since it starts in a bootstrapper scene, these fields within the singleton are null until it gets to a certain scene. Right now, im just using GameObject.Find to find that empty gameObject to spawn the enemies on but i dont really like this way since it needs to check everytime the scene is changed

like it works completely fine but I feel it could get messy especially with wrong strings, etc

[rigid island]

hm yeah at least i would not use string / Find. where is the FindObjectOfType? mind as well slap that onto it

[merry stream]

well its just an empty gameobject so findobjectoftype wouldn't work

i could just make an empty class but eh

i dont like that either

[rigid island]

put a component or have something already in that scene hold reference

imo using a component is at least type safe

[merry stream]

true

[errant flame]

can i override plus minus list view button actions in inspector without touching whole inspector editor things

[rigid island]

and they are supposed to what exactly ?

doubt any way to do this without editor scripting

[soft shard]

You can create your own reoderable list, although it is going to require editor scripting, as navarone mentioned, theres no easy way to modify Unitys inspector code, although all it does is add and remove from a list, then refreshes the drawer for that list to show the updated element, what other functionality might you need for something like that?

[storm wolf]

I have a really dumb (probably) question.

So I am currently trying to make save system and I have this setup

    [Serializable]
    private class CoinData : Data
    {
        public int value;

        public CoinData(int val)
        {
            value = val;
        }
        public static CoinData Create(int val) => new CoinData(val);
    }

This is strictly just an example/test I have set up that saves just an int value. Essentially my saver/loader saves the Data type - the base class is literally just empty - my thought is that each saveable thing can derive from this to implement what it saves and then pass it through the save function that takes in a Data . all is well, I went through the debugger up until the point where it gets turned into JSON:

 string json = JsonUtility.ToJson(data);

 File.WriteAllText(dir + fileName, json);

after this writes to the file, instead of writing the derived CoinData class with its value (which I know it has right before writing) it writes an empty Data class and loses the value entirely. Does the JSON parser not support what im trying to do, am I doing something wrong, or am I just stupid. Help would be appreciated, thanks!

Both classes are [Serializeable]

[wide terrace]

How are you obtaining data?

[storm wolf]

    public static bool Save()
    {
        OnSaveGame?.Invoke();

        SaveData data = new SaveData();

        string dir = Application.persistentDataPath + directory;

        if (!Directory.Exists(dir))
            Directory.CreateDirectory(dir);

        string json = JsonUtility.ToJson(data);

        File.WriteAllText(dir + fileName, json);

        Debug.Log("Saving Game");

        return true;
    }

and as of now I am using this in my constructor:

    public SaveData()
    {
        UnityEngine.Object.FindObjectsByType(typeof(GameObject), FindObjectsSortMode.None)
        .ToList()
        .Where(x => ((GameObject)x).GetComponent<ISaveable>() != null)
        .ToList()
        .ForEach(saveable =>
        {

            string id = ((GameObject)saveable).GetComponent<UniqueID>().ID;
            idToSaveableItems.Add(id, new(((GameObject)saveable).GetComponent<ISaveable>().GetData(), ((GameObject)saveable)));
        });
    }

heres the json:

{"idToSaveableItems":{"keys":["93f53778-351b-44de-b203-5f8ee2e3f5f4","08c14717-39a1-4a49-86e4-0d8e4641ded8"],"values":[{"Data":{},"GameObject":{"instanceID":31886}},{"Data":{},"GameObject":{"instanceID":31878}}]}}

[wide terrace]

Is uhh... ISaveable.GetData() returning a Data, then?

[storm wolf]

correct

[wide terrace]

So I think the issue is that if you're serializing a reference to a Data, the only members available are those which exist on Data, even if the reference points to an instance of a derived class.

There might be a way to make it work using generics... though then you'd need to know the type of Data from within SaveData() ahead of time... hmm...

[storm wolf]

so what then make Data generic and then check for each type that T could be or like

damn that sucks 😭

[wide terrace]

Perhaps you could just have GetData() return the serialized data object?

oh but...

🤔

[storm wolf]

yeah it wouldnt be Data anymore lol

im thinking about your generic proposal im not sure kind of approach I could take yet

[Serializable]
public class Data<T>
{
    public T data;
    public Data(T d)
    {
        data = d;
    }
}

thoughts on something like this

any chance that can get serialized

and then like

  public Data<CoinData> GetData()
  {
      return new Data<CoinData>(CoinData.Create(value));
  }

[wide terrace]

...maaaaybe? 😅

I think that might have the same issue in that SaveData() still wouldn't know the type, since all it knows is that ISaveable.GetData() returns a Data<T>

[storm wolf]

hmm you are probably right

any ideas?

[wide terrace]

Nothing terribly clean or concise... I'll play with something for a bit though and get back to you... I reckon someone else may have more useful thoughts on the matter 👀

[storm wolf]

okay ill play around with it too just @ me if you come up with anything appreciate the efforts

[wide terrace]

It sounds like Newtonsoft Json.net might be able to handle this sort of generic serialization/deserialization stuff with it's TypeNameHandling.Auto... Though it sounds like unless you include some sort of validation prior to deserialization, it could enable users to instantiate any type by modifying the Json.

Other than that, in my limited C# experience I don't see a way around using explicit types in at least half of the serialization/deserialization lifecycle 😦

[storm wolf]

darn 😦 really thought this was doable. Thanks for looking into it I will probably cage it for tonight... all i could find was custom serializer stuff which sounds icky.

guess i will need multiple dictionaries 😪

[proven jasper]

Wanting to prevent user modification is directly at odds with using json at all really

There's zero advantage to a json based approach if you dont actually want users to be able to view and edit save game data, might as well save the space and use binary then

Also as you said, Json.net will handle this fine

[thin hollow]

I'm not sure if I should be asking it here or in #✨┃vfx-and-particles , but seems more like a code question than a particle system setup question...
How do you build pooling system for your particle effects? Or, rather, how do you store and apply particle system setting to particle emitters? I thought you can do it through presets, but it turns out they're UnityEditor and won't be accessible at the runtime.
So I'm not sure how to proceed, either I'll need to make a separate pool manager for every. single. visual. effect. in the game, or just say "fuck it" and instantiate game objects from a prefab ref each time, like a dirty peasant.
Neither feels like a correct solution.

[wide terrace]

Oh, absolutely 👍

The thought that crossed my mind is that if instantiating any type from such a file is enabled, it may be possible to craft an actually malicious JSON file... For things like save files which players may be inclined to share and assume to be innocuous data, that scares me a little bit.

But admittedly it's still probably not much worse than anything else which they might share

I guess it would probably also require some intimate knowledge of the game logic to actually do something malicious with those types

I'm likely overestimating the threat 😅

[proven jasper]

I could swear that Json.net actually has guidance onhow to handle this specifically

I know at the very least it throws up a warning if you enable this sort of object creation without some additional handling

Honestly, I never looked into it more than that though. My philosophy is more along the lines of tossing a disclaimer on the splash and then letting people compile text files to C# at runtime if they'd like

[wide terrace]

I did find some excerpts to that effect which others were quoting, but which I failed to find in the docs. Albeit I didn't dig too much further

[wide terrace]

Yeah that's totally fair 😁

[proven jasper]

https://stackoverflow.com/questions/67929193/is-it-possible-to-prevent-the-json-net-typenamehandling-vulnerability-with-a-mar this seems on point

Is it possible to rotate 2d Colliders? I'm making a 3d top down game but its actually just a 2d top down game with 3d graphics in disguise, so it only requires 2d collision checking. Would be cool if I could just rotate my 2d collider 90 degrees

[mellow sigil]

You should instead rotate the entire game so that it's on the x/y axis

[open plover]

That is a valid option but I would rather not do so

[mellow sigil]

Then you can't use the 2D physics engine

[open plover]

Nothing else I can do?

[mellow sigil]

nothing that would be reasonable by any measure

[errant flame]

for example if i use find property method and add that property auto history methods of inspector will working i mean (CTRL-Z , CTRL-Y etc)

if i add a custom property drawer there is no way to do that i guess do i need to implement also that logics

[errant flame]

        private void OnValueChange(SerializedProperty property, ChangeEvent<string> evt)
        {
            bool isInteger = int.TryParse(evt.newValue, out int value);

            property.stringValue = GPSelectionData.SerializeValue(isInteger ? value : evt.newValue);
            bool needToUpdate = property.serializedObject.ApplyModifiedProperties();
            if (needToUpdate)
            {
                property.serializedObject.Update();
            }
            Undo.RecordObject(property.serializedObject.targetObject, "property");
        }

i made a custom property drawer and use a text field , when i use CTRL-Z on native properties that undo system works well but not for custom ones , so i put a record state on value change callback but when i undo its performed well but there is no graphical changes on property how can i do that

i tried this but not worked after undoRedoPerformed i guess property or serializedObject getting null any idea ?

            Undo.undoRedoPerformed += () => EditorUtility.SetDirty(property.serializedObject.targetObject);

[thin hollow]

Tried to do it this way, but while properties are being copied, I think it somehow breaks the emitter in the process...

[thin aurora]

Consider switching to Newtonsoft. JSONUtility sucks and you should not use it apart from legacy code

Even if you made a mistake in your code, it is unable to detail the issue and would rather return empty objects. Newtonsoft will actually inform you of the issue if there is one. Emphasis on if there is one because JSONUtility can even fail on correct code

Note by default Newtonsoft serializes properties, not fields. This is default with serializers so you will have to either add a property to serialize, or configure it to use fields.

[wintry crescent]

does anyone know if the .transform call is cached by unity? Or is it like getcomponent. It wouldn't make sense to not be cached

should I make my own cache or is it unnecessary

[knotty sun]

unnecessary

[wintry crescent]

so it's cached, then?

[knotty sun]

well, no, not as you are thinking of cached, transform is a C++ object which is referenced by C# code

[wintry crescent]

but there isn't a GetComponent style call - that's my point

[knotty sun]

no

[wintry crescent]

good

thanks

[cold parrot]

It forces a transition into unmanaged code which has a small overhead. If you use the transform in performance critical sections where the transform access is the actual bottleneck you can cache it to gain some performance, that benefit is however gone when you write to it. It would only be noticeable in fully data oriented systems that optimize for cpu cache friendly data access.

[grizzled vine]

I'll ask this in general I suppose:

I've been trying to optimize my AI recently, as, having 50 Navmesh Agents on screen at once right now, causes Frame Rate Drops. This is mostly due to the amount of NavMesh.CalculatePaths that I'm calling.

public bool CanReachPoint(NavMeshAgent inAgent, Vector3 inPoint) {
        NavMeshPath path = new NavMeshPath();
        NavMeshQueryFilter filter = new NavMeshQueryFilter {
            areaMask = inAgent.areaMask,
            agentTypeID = inAgent.agentTypeID
        };

        if (NavMesh.CalculatePath(inAgent.transform.position, inPoint, filter, path) && path.status == NavMeshPathStatus.PathComplete) {
            return true;
        }
        return false;
    }

At the end of the day, my goal is to find a location where the AI can move to around the player, but also, ensuring they can shoot the player from that position. As, my level design could have no path towards the player, but, they could still shoot the player from that location. The current steps I ended up taking, were basically at the start of a level I will build a bunch of "Tether Points" around the world which would update every X frames to check to see if the AI can shoot the player from that location. From there, they check every X frames if they can reach one of those points (Where the code above is.)

The problem I suppose, is, I'm not sure how to optimize it more? As the calculate path call seems heavy.

I guess I could, for example, check to see if the node is apart of the same Navmesh area? Im not sure if thats possible. But the idea being is, if Node A is on Navmesh Area 22, and Node B is on Navmesh Area 23, then checking if they can reach that point is valid. However, if Node A and Node B are both on Navmesh Area 22, there is no point in checking both, as its unlikely they can reach Area22?

[cosmic rain]

Yes. The first one would not compile in a build.

[cosmic rain]

Did you actually do any profiling or are you basing off assumptions?

[grizzled vine]

I've done Profiling, and disabling the CalculatePath causes a massive performance boost.

[cosmic rain]

Can you share the profiling data/findings?

[grizzled vine]

Anything specific you're wanting to see?

[cosmic rain]

Mainly what's taking most of the frame time, how much it's taking and how many calls are made.

[cosmic rain]

Can you expand the topmost update?

[grizzled vine]

A lot of GC.Alloc's

[cosmic rain]

Yeah, so the issue is probably not the path calculations

[grizzled vine]

(Nothing else.)

[cosmic rain]

but GC.

[grizzled vine]

I'm not sure what would be causing the GC to build up like that then hmm.

[cosmic rain]

One cullprit is definitely the .ToList()

That allocates a list each time.

assuming, stateMachineTimers is a dictionary, can't you just foreach a stateMachineTimers.Keys instead?

[grizzled vine]

Cant when modifying it but I'm sure I can work around it.

Using a box collider with 0 on the y scale seems to simulate 2d box collider on a x,z plane

hmmm this might not work, but try setting the duration to something small, like 0.01

Still throwing a lot of GC with

            var key = stateMachineTimers.ElementAt(i).Key;
            stateMachineTimers[key] -= Time.deltaTime;
        }

Though I assume that might be caused by ElementAt now.

[night storm]

why not just iterate over the keyvaluepair?

[cosmic rain]

Yeah. It's probably allocating a list or array behind the scenes as well.

[grizzled vine]

You mean via a foreach?

foreach (var item in stateMachineTimers.Keys) {
            stateMachineTimers[item] -= Time.deltaTime;
        }

The value can't be modified via that.

[whole plaza]

Answer me pls

[vagrant blade]

If the animation is animating the position of the object, it will override any changes you try to make.

Child the animation to a root object instead and drag the root object. This may require you to reanimate the child so that it's position is local space.

foreach(KeyValuePair<string,float> pair in dictionary)

doesnt this work? idk if this allocates anything though

[knotty sun]

It can, the problem is your value is a value type (float), wrap that float in a class and then you can modify it in the foreach

[grizzled vine]

Yeah this was my next thought I was going to try.

[grizzled vine]

Nope, still causing GC.Alloc.

[whole plaza]

this is exactly what i have done

but it just doesnt work

[knotty sun]

what is the type of your TKey ?

[grizzled vine]

String.

It is a <string,float> pair originally, and now its <string,class>

[wintry crescent]

and will everything work, if I just skip the allowSceneActivation thing?

[knotty sun]

that string will be your GC alloc

[wintry crescent]

OH WAIT IM STUPID

no wait
after switching > to < it still doesn't work

[grizzled vine]

Tried moving to a full class/struct based system.

foreach (var item in stateMachineTimers) {
            item.timer -= Time.deltaTime;
        }

Still causing the GC.Alloc.

Did the allocated amount change at least?

It could be more than just that part

                if (scenes[i] < SceneManager.sceneCountInBuildSettings)
                {
                    LoadSceneMode loadSceneMode = i == 0 ? LoadSceneMode.Single : LoadSceneMode.Additive;
                    AsyncOperation loadOP = SceneManager.LoadSceneAsync(scenes[i], loadSceneMode);
                    loadOP.allowSceneActivation = false;
                    loadOperations.Add(loadOP);
                }
            }   
            
            foreach (var operation in loadOperations)
            {
                yield return new WaitUntil(() => operation.isDone);
            }
            foreach(var operation in loadOperations)        
            {
                operation.allowSceneActivation = true;
            }
                Debug.Log("");
            IsLoading = false;
        }```

[grizzled vine]

Nope.

And commenting out the forloop will remove the issue completely.

[knotty sun]

change the foreach to a for

[cosmic rain]

And btw, foreach itself might be allocating as well.

[grizzled vine]

Yeah was just about to try that.

Nope. For loop also causes it.

Hmm. Okay, its not from that. Profiler was just, wrong and isn't digging deep enough apparently. Commented out the rest of the code, manually set timers, and no GC.

[cosmic rain]

You mean that the first time it works correctly, but after that doesn't? Or it is stuck with loading endlessly even on the first coroutine?

[wintry crescent]

stuck loading the requested scenes endlessly, previous scene works as normal

I can see them loading in the inspector

operation.progress >= 0.9f instead of operation.isDone didn't fix the issue when list is bigger than 1

[wintry crescent]

it happens with the first corouitne

[grizzled vine]

Yeah so, back to the

public bool CanReachPoint(NavMeshAgent inAgent, Vector3 inPoint) {
        NavMeshPath path = new NavMeshPath();
        NavMeshQueryFilter filter = new NavMeshQueryFilter {
            areaMask = inAgent.areaMask,
            agentTypeID = inAgent.agentTypeID
        };

        if (NavMesh.CalculatePath(inAgent.transform.position, inPoint, filter, path) && path.status == NavMeshPathStatus.PathComplete) {
            return true;
        }
        return false;
    }

It appears to be due to the Filter and Path as the leading cause of GC.Alloc. I still have SOME commenting it out, but, not nearly as much.

[cosmic rain]

Kinda sounds like you keep on starting the coroutine.

[wintry crescent]

no. I start it once

[cosmic rain]

Path you can cache as a class field. Filter probably as well.

[cosmic rain]

Log something meaningful when you call load scene.

[spare island]

did you do allowSceneActivation = true

once progress is at 0.9

[wintry crescent]

that's what the code should do, I'd hope, yea

[spare island]

unfortunately can't read the code on mobile

[wintry crescent]

private IEnumerator LoadScenes(List<int> scenes)
        {
            Debug.Log("Starting loading the scenes");
            if (IsLoading)
            {
                yield break;
            }

            IsLoading = true;
            List<AsyncOperation> loadOperations = new();
            for (int i = 0; i < scenes.Count; i++)
            {
                if (scenes[i] < SceneManager.sceneCountInBuildSettings)
                {
                    LoadSceneMode loadSceneMode = i == 0 ? LoadSceneMode.Single : LoadSceneMode.Additive;
                    AsyncOperation loadOP = SceneManager.LoadSceneAsync(scenes[i], loadSceneMode);
                    loadOP.allowSceneActivation = false;
                    loadOperations.Add(loadOP);
                }
            }   
            Debug.Log("Loading started");
            int s = 0;
            foreach (var operation in loadOperations)
            {
                yield return new WaitUntil(() => operation.progress >= 0.9f);
                s++;
                Debug.Log(s + " scene Loaded!");
            }

            Debug.Log("Loading ready");
            foreach(var operation in loadOperations)        
            {
                operation.allowSceneActivation = true;
            }

            Debug.Log("allowed scene activation");
            IsLoading = false;
        }

2 scenes are being loaded in this example

[spare island]

I'm assuming you're making a loading screen

[wintry crescent]

and it looks like this

ah wait I got an idea...

I'm stupid. It works now

had to move the allowSceneActivation to the previous foreach loop

[spare island]

I don't get why that works but if it does 👍

I'm using a package from github, but wanted to tweak it a bit so just dropped it's source in my Assets/. The package has a namespace - the rest of my code doesn't. I can use the package code in mine no problem via adding a using statement. But I wanted to add variable of my monobehaviours into one of its definitions and I can't, I'm getting error CS0246: The type or namespace name 'RagdollController' could not be found (are you missing a using directive or an assembly reference?) The external code contains asmdef files (one for runtime and one for the editor part) is there a way I can edit the asmdef's to allow referencing my Asset/Scripts code?
(I think I could move the code into my Scripts directory and remove the included asmdef files, but maybe there's a right way to do it?)

[spare dome]

Osteel helped you then

[whole plaza]

yeah

click my message above then scroll up

wdym by "doesn't accept"?

[open plover]

Says it needs at least one triangle to be valid

[rigid island]

show the object you're trying to drag and where you placed the script

[cosmic rain]

Did you assign the triangles/indices array?

[cosmic rain]

So, no then.

[craggy falcon]

hey, im following a tutorial for a natural-feeling character controller. ive copied the code exactly - the errror I am getting is relating to the MonoBehaviour part of the class. The class is public, the name is exact(yes, including capitalisation) and the script editor does not notice any errors. However, Unity won't let me add it to any gameobjects because, aparrently it doesn't derive from MonoBehaviour. Can somebody explain what I'm doing wrong here? ^^; it seems like it should work, but i just can't see any errors. I've copied working code letter for letter and i've checked 5 times, capitalisation throghout the script is exact.

(The script im working on is a custom InputManager script, and I've created a GameObject to attach it to called INPUT, again copying the tutorial to a T. I've done exactly what he's done, yet it isn't working and I don't quite understand why because as far as I can tell, everything is correct)

[cosmic rain]

A valid mesh has to have triangles assigned as well.

[rigid island]

I would advise you go through this maybe ?

[open plover]

ok im fixing it

[rigid island]

keep reading

[open plover]

yep just saw that part

[cosmic rain]

I don't know if it was different at the time of the tutorial writing, or it's simply a mistake, but you need to define the triangles. Look at the next section of the tutorial.

[open plover]

yes I didn't see that pat

[rigid island]

please use links for large code as it was stated in the bot

[open plover]

I'm guessing I would need 2 triangles for a simple square?

[cosmic rain]

Yes.

[craggy falcon]

oh sorry, i didn't realise it was that large. I'm a little unsure how to work it though - give me a sec and I'll fix it

[rigid island]

do you have another class named PlayerInput

[craggy falcon]

It wasn't stated in the tutorial, but it was pre-attached when he began recording. He's not shown any other scripts before cracking on with everything else so I'm not too sure. I'm just copying what he's shown

[knotty sun]

can you link the video

[craggy falcon]

https://www.youtube.com/watch?v=zHSWG05byEc

I've just followed the steps he's showing in order

[rigid island]

send link to script again, also yeah half the shit isnt even shown..not a fan of that style

[open plover]

still the same issue

[craggy falcon]

sorry, how do I link it exactly? ^^; (im pretty new to text formatting on Discord and such, sorry)

[open plover]

added this

[rigid island]

paste the code inside one of the links the bot linked, hit save and send link

[cosmic rain]

Share the updated code..

[grizzled vine]

Yeah so I'm now back to the following code causing the problems:

public bool CanReachPoint(NavMeshAgent inAgent, Vector3 inPoint, NavMeshQueryFilter inFilter) {
        // if (NavMesh.CalculatePath(inAgent.transform.position, inPoint, NavMesh.AllAreas, path) && path.status == NavMeshPathStatus.PathComplete) {
        //     return true;
        // }
        return false;
    }

Commenting out the CalculatePath, the game runs perfectly fine/smooth. Using the NavMeshQueryFIlter which is cached on Start, causes more GC.Alloc to appear than using NavMesh.AllAreas. However, both cause massive performance hit.

[rigid island]

probably be better instead of calculating path on each enemy , you have 1 script calculate path for each one

[grizzled vine]

The function gets called via:

public bool HasPossiblePoint(NavMeshAgent inAgent, NavMeshQueryFilter inFilter, AITargetSystem.ShootHeights inShootHeight) {
        foreach (var item in tetherPoints[GetHeightModifierAsFloat(inShootHeight)]) {
            if (item.canSeePlayer && CanReachPoint(inAgent, item.point, inFilter)) {
                return true;
            }
        }

        return false;
    }

Where I first check to see if they can even see the player from that point, before checking to see if they can reach it.

[open plover]

ok I fixed the error but this is just a triangle and not a square

[knotty sun]

I was wondering whether you might want to consider the problem from a different perspective, have the Player figure out where it can be seen from and then tell the AI's this info

[open plover]

I better follow a guide cuz I had no idea how meshes worked prior to 10 mins

[craggy falcon]

would you prefer a specific link? idrk how these work ^^;

[cosmic rain]

Well, the indices you shared earlier are for a triangle. Not a square.

[rigid island]

any is fine
https://gdl.space is easiest

[craggy falcon]

okay, thanks for letting me know :)

[grizzled vine]

Thats already handled elsewhere. I use a HiveMind system where that figures all that information out, and is already performant.

[craggy falcon]

do I just paste it and then save it?

OHH i got it

[craggy falcon]

https://gdl.space/xihoxadage.cpp
I think this is it!

[grizzled vine]

?? That wouldn't work. A path from Point A to Point B where each enemy is a different Point A?

[rigid island]

yeah .
how about the error message

[cosmic rain]

Did you profile after moving the filter and path to Start? What allocates the garbage at that point?

[craggy falcon]

It wont let me copy/paste text, shall i screenshot it?

(I copy it but nothing pastes but what I previouslt had in my clipboard)

[rigid island]

wdym wouldn't work? I do it lol sometimes its better than having a MB on each enemy doing calculations

[open plover]

working now

[rigid island]

yea

[grizzled vine]

The calculate path itself causes it. No question at all at this point in time.

[open plover]

I'm just trying to create an 2d box collider on the x,z plane idk if this is an overkill

[rigid island]

there might be another script named InputManager ?

[cosmic rain]

Share the profiler data

[grizzled vine]

If an enemy a is in one corner of the map, and enemy b is elsewhere, and they both want to go to the same point, that is a different path...

[cosmic rain]

Also, capture it with deep profiling on.

[rigid island]

yes but rather than 2mbs calculating that i found it cheaper 1 mb calculates paths for each

since each instance is another MB that needs to call backend code

[cosmic rain]

Might be wrong, but it seems like they're doing that already.

[rigid island]

ohh are they ? didn't see the full code , I just assumed from method but yea does seem to take Agent as param ?

[storm wolf]

Hmm this sounds good. I will attempt the switch and report back

[cosmic rain]

Yeah, they didn't share the whole code, so I'm assuming here as well.

[rigid island]

I just had a crazy epiphany with MB recently through profiling and testing that , eager to share 😛

[cosmic rain]

It seems like HasPossiblePoint is what's allocating. Not the CanReachPoint

Also, it's allocating just 100 Byte. But you're allocating 12.7kb in total on that frame

This isn't even what's taking most of the frame time

[grizzled vine]

There are 50~ of these happening.

[cosmic rain]

Well, there's something really wrong with the way you structured your code and it's really hard to guess from the little pieces of info that you're giving us.,

None of the stuff in this screenshot is taking any considerable time.

You should Share more of the profiling data, sorted by cpu time and/or the gc allocations as well as the relevant code

[languid hound]

No idea if I'm being stupid but does anyone see something wrong with this coroutine? When I set my duration to something like 60 it only lasts a second

    public IEnumerator SmoothTransitionToZPos(float newPos, float duration)
    {
        float counter = 0f;
        float temp = 0f;

        while (counter < duration)
        {
            counter += Time.deltaTime;
            temp = Mathf.SmoothStep(0, 1, counter / duration);
            zPos = Mathf.Lerp(zPos, newPos, temp);

            yield return null;
        }

        zPos = newPos;
    }

I've never used SmoothStep much so I don't know if it's something to do with that

I tried dividing the deltaTime that was added onto the counter as well but that gave the same result

[rigid island]

idk about smoothstep but lerp is wrong

[languid hound]

How come?

[rigid island]

nvm actually, Mathf.SmoothStep is affecting it so you have to fix that first if its wrong . In example unity uses Time.time

[craggy falcon]

there is a secondary one in the ordinary packages section... do I move the location of the one I've edited? or delete the second inputmanager?

[languid hound]

I tried without lerp but it seems to go super fast with that too

Sorry not lerp I mean smoothstep

[rigid island]

yeah its not lerp, its smooth step

[languid hound]

I don't use smoothstep currently and the issue still occurs

[rigid island]

https://docs.unity3d.com/ScriptReference/Mathf.SmoothStep.html
the example here doesnt use time.deltaTime
I suspect thats the issue

[rigid island]

show updated code

[languid hound]

Literally just this. I'll try to use the method they use in that doc to elapse time though

    public IEnumerator SmoothTransitionToZPos(float newPos, float duration)
    {
        float counter = 0f;

        while (counter < duration)
        {
            counter += Time.deltaTime / duration;
            zPos = Mathf.Lerp(zPos, newPos, counter);

            yield return null;
        }
    }

[rigid island]

ehh maybe rename yours with F2
never heard of the other one, better safe than sorry though

[grizzled vine]

There are 50 * 140 = 7,000~ calls to Calculate Path right now taking up 0.03ms per Calculation on average. (Some are shorter mind you) which equates to the total 142ms per frame.

I'm not sure what else you're asking to see, but it adds up perfectly fine.

[craggy falcon]

Okie dokie. just looked and I can't delete it anyway, so I'll do that now :)

ah rats can't rename it

[rigid island]

https://unity.huh.how/lerp/coroutines
look at this example for lerp

you just put / duration in wrong spot

ur only dividing the time between frame not the accumulated value

[cosmic rain]

So you have 50 of these FiniteStateMachine.Update?

[grizzled vine]

Correct.

[cosmic rain]

I'm asking to see the whole picture. With the profiler data sorted correctly.

[rigid island]

why not

is it trying to rename the other one as well ?

[craggy falcon]

it's just blacked out, alongside delete. I moved one elsewhere, deleted it, and then it replaced itself and it's as if it was never removed in the first place

[rigid island]

well idk that sounds like something werid is happening, or take a ss of it

[craggy falcon]

and suddenly I'm getting errors now. I missed a semicolon, but it's telling me that there's still one expected on the line? which is so weird? since it's been updated and saved, ONE error is gone, but there's two others from the same line. damn Unity's not been my friend this week. I've failed 3 different setups. I really hoped this one would work.

[craggy falcon]

Lemme get a ss

[cosmic rain]

Okay, then one simple solution would be not to update all the agents every frame. Update one or several of them each frame. But to be honest, that many calls to calculate path are really unreasonable. Might be better to come up with a better system.

[cosmic rain]

It's also likely that the GC is contributing a lot to it. Might want to get rid of that 100 byte allocation.

[rigid island]

yes because its part of a Package probably and read only

rename yours instead ofc

but that only renames the file

open the class and rename that using F2 it *should * rename the file too

[grizzled vine]

Which was my original question... Lol I was trying to figure out a better System here.

The goal is to let them find a location that: A: They can shoot the player (Calculated for the entire Level every X frames and is Performant.) and B: That they can reach via NavMesh.

[craggy falcon]

huh... how come it'd let me edit it then? i find that very confusing Unity >:/ (nbh just realising after alot of research Unity has tonnes of non-specific errors and allow things that shouldn't be allowed sometimes lol.)

[craggy falcon]

alrighty, i'll give it a go

[rigid island]

yeah idk everyone has different packages, I usually just use namespaces to avoid naming conflicts

[craggy falcon]

it blows my mind how people can use Unity as if it's as simple as reading a book 😭 i know one day I will reach that level of mastery, if only Unity had more specific errors and solutions lol

[rigid island]

it takes time and experience thats all

eventually you will run into the same issues and you ~~slowly ~~ learn how to avoid them altogether

[grizzled vine]

Removed and same performance.

[craggy falcon]

GOD i hope so. it's now telling me that the class can't be found. I've renamed it, COPIED AND PASTED the name, so I don't know how it can't match. AND it still has these line end errors depiste me fixing that one. god knows.

[rigid island]

did you rename the class and did it rename the file ?

can you ss it
btw next time this would be in the #💻┃code-beginner section

[cosmic rain]

For starters, you can split the workload into several systems:

• update several of the positions every frame and cache the state of whether the player is reachable/hittable from there. Maybe have a separate list of these positions sorted by most desireable(player is reachable) to less.
• update several npcs every frame. If they need to move to a new position, check if they can get to the most desirable position first. If yes, break the looping and reserve the position.

[craggy falcon]

I did yea, lemme grab it.

[craggy falcon]

Might just pick a different name by adding just a letter or something and removing "player".

[ionic blaze]

The class 'Editor' was depricated in the latest version of Unity (6.0.15), but the link in the release notes as to why wasn't put in. What should we be using instead of deriving from Editor? It's caused havoc in the project from all the editor scripts that derived from Editor. Anyone know how to handle this yet?

[spare dome]

you have to rename the script name and the name in the script for a script to work

[cosmic rain]

Then there are game design considerations that could help. For example: enemies shouldn't change their destination while already moving somewhere. That would save you a lot of calls to navmesh.

[spare dome]

you have spaces on the actual script name but no spaces in the actual script

[craggy falcon]

that's what I did, that's why I'm confused.

[spare dome]

you renamed the actual script in the project window?

[craggy falcon]

OH i fixed it. I had a mistype but the error did NOT specify that the word I had typed was "not an argument" or whatnot. It was talking about the END of the line wierdly enough

I have attached the script to the game object now. Hooray for indirect and non-specific unity errors! /sar /silly

thanks for your help guys - it was probably more than just that and what I was told has also helped for future projects. Thanks so much <3
Not gonna be the last you see of me though lol. Sure i'll see you soon!

[grizzled vine]

I do the first already. The first is if they can shoot the player. This takes my Tether Point count down from 500~ to 140~. So thats already cutting the number of possible points up. I'm also only checking the points that are within Camera View (As they can technically only shoot the player when in Camera View.)

Every X Frames is what I'm doing as well in this case. Though its possible this is bugged looking into it a little bit more right now.

And lastly on your other comment about Game Design: Enemies can change their position, however, only after X seconds. Otherwise, they move, stop for X seconds while attempting to shoot the player there, then move away.

[cosmic rain]

Not "every x frames". "X object updates at most every frame"

[grizzled vine]

Right, you're talking more about staggering them.

[cosmic rain]

I don't know what these 140 points are doing, but if it's heavy, then spread it across several frames, as I mentioned.

[cosmic rain]

Staggering?

[grizzled vine]

Staggering/Spreading it throughout all the frames.

And 140 Points aren't heavy at all.

[cosmic rain]

Even if you update one out of 50 npcs every frame, updating all of them is less than a second at 60 fps. The player wouldn't be able to notice any difference, unless they have access to debug info and see exactly when the decision of each npc is made.

[cosmic rain]

Yeah, spreading through the frames. Never heard "staggering" being used in that context.

Anyways I'm off to sleep.

[ionic blaze]

Found the issue. Probuild 6.0.2 introduces a root namespace 'Editor' which breaks every editor script in the engine. Reverted to probuilder 6.0.1 to fix the issue.

[storm wolf]

Hey so I have switched to newtonsoft. Everything saves correctly. The problem before was it was saving the Data class as just empty. This time it does SAVE the data correctly, but the data gets lost when it is loaded.

{"idToSaveableItems":{"08c14717-39a1-4a49-86e4-0d8e4641ded8":{"value":66789},"93f53778-351b-44de-b203-5f8ee2e3f5f4":{"value":1423}}}

heres the json that is in the file, but when the json gets converted back into a SaveData this is what I get:

(cc @wide terrace ) #archived-code-general message

[grizzled vine]

At the end of the day, is it possible to check what Navmesh Section a point is on? Take for example these two areas. If a agent is unable to reach the bottom right corner of the navmesh, they are obviously unable to reach anywhere else on it due to the navmesh gap shown inbetween the red and the purple.

If its possible to know if a point is apart of the red navmesh vs the purple one, I feel as if I could improve performance greatly in this case.

[knotty sun]

https://docs.unity3d.com/ScriptReference/AI.NavMesh.SamplePosition.html

[grizzled vine]

This only samples it and returns a point on the navmesh, unless the returned mask returns a different number for each section. This is a singular navmesh in this case, not multiple

[odd void]

i want to implement a third person camera wich looks at the player when moving the camera, it works on the x-axis but not the y-axis... what can i change about my code?

https://hastebin.com/share/jerikujeba.csharp

[knotty sun]

this will return false if the point is not in the area(s) specified

[storm wolf]

Save/Load system parsing issue

[grizzled vine]

But the area in the red and the area in the purple are considered the same navmesh area. It's a singular navmesh, where it's just one wall blocking it for example.

[knotty sun]

This is starting to turn into a typical XY problem, it's like you're trying to fight your way out of a paper bag instead of just removing the bag. Take a step back and re-evaluate your whole system and approach to it

[lean sail]

Not sure exactly what you're trying to do either but you could use Bounds to see if the point is at this location. Put an object at the center there and a Bounds roughly on the same shape

[grizzled vine]

Basically, the main goal, is to locate a location on the Navmesh that:

1: The AI can move to.
2: The AI can shoot the player at.

The shooting the player I pre calculate globally for all enemies, however the being able to reach the position, I need to check with CalculatePath, which is expensive when you run it over 7000~ times.

[north vine]

does anyone else experience bugginess when using gameobject arrays in inspector? i have to restart my editor whenever i want to add something to an array, is there a workaround?

[gray mural]

How do you add them?

[gray mural]

Works fine on my device. What exactly is not right for you?

[north vine]

hmm maybe it's caused by some plugin i have installed then, or maybe it's the current unity version i have, either way i get this spam in log and have to restart editor:

[gray mural]

Does restarting editor mean restarting Unity?

[north vine]

yeah

[gray mural]

And it's not fixed every time?

[north vine]

when i restart the editor it gets fixed, it's some sort of editor bug i guess

[gray mural]

Why do you ask the question if it's fixed?

[north vine]

well i have to restart every time i add something to an array it's unusable... it only fixes that one element every time i restart

[gray mural]

The majority of Unity bugs are fixed by reloading Unity once

[gray mural]

Oh, I see

Please, show the code

Is it a simple array of GameObjects?

[north vine]

it's a public List<GameObject>

[gray mural]

The issue is probably in one of your packages

[north vine]

will take a look at packages then, thanks

[gray mural]

This answer mentions the version control package

[storm wolf]

Or try upgrading your editor version too if looking into the packages doesnt work

[knotty sun]

I would suggest there is a problem with your asset database. Close your project, delete the Library folder and reopen your project, this may take some time

[lean sail]

If you're running it 7000+ times often, I'd first see why that happens and put a limit or reduce the amount of logic being done.
Theres not really a way around it unless you can somehow precalculate this too

Thatd imply no collision avoidance on other agents though

[north vine]

tried this, didnt help

[knotty sun]

which version of Unity are you using?

[north vine]

2022.3.9f1, should i update to a newer one?

[knotty sun]

definitely, 2022.3 was not stable before .11

[craggy falcon]

why would this code need a comma? Error is telling me Syntax error, ',' expected

[Range(0f, 1f)] public float HeadWidth 0.75f; (From an earlier post in #💻┃code-beginner)

0.75f; is underlined red but im not sure what the error is?

[knotty sun]

did you configure your IDE?

[spare dome]

you need an =

before the 0.75f

[craggy falcon]

yep, it's underlining and everything now, it's just doing a thing

[knotty sun]

just compare this line with the one before it. Notice the difference?

[craggy falcon]

Oh. thanks, i missed that. it's not in his code and his doesn't have an error! man im noticing these tutorials must have something that nullifies their errors. it's been like 3 different tutorials that seem to show no errors when they're coding when there are mistakes i've had to correct in mine before

god my mind slipped that

(plus why can't Unity tell me i'm missing an equals sign 😭 over a comma)

[spare dome]

they either dont have thier IDE configured or they just write it correctly

[knotty sun]

because. following C# syntax, it thinks you are trying to decalre 2 varaibles rather than one and 2 variables would be seperated by a comma

[craggy falcon]

ahh right.

[north vine]

updating to 2022.3.42f1 seems to have fixed the issue, thanks! 🙂

[knotty sun]

excellent

[stone echo]

Having trouble figuring out tweening for my project. I have a camera that zooms in and out on button press using tweening over 0.2seconds (zoomto is a tween call):

[gray mural]

Is it possible to get the distance between the Vector2.zero and Vector2.right anchors in local coordinates without reassigning the anchors twice or enumerating through every parent's parent?

[stone echo]

I also want the camera to follow the platformer when in platformer mode:

This however doesn't work because if put in update, its snapping to the location mid tween which makes things break. What is the best way to deal with this?

[rigid island]

RectTransformUtility you could use I think

[gray mural]

I am not sure, are you having troubles with continuously zooming the camera in?

[gray mural]

It does not seem to have any suitable methods

[rigid island]

oh wait I think I misread what you're asking

[gray mural]

Here, I am basically asking how to keep the RectTransform's position same when changing anchors & pivot

[rigid island]

not sure what that means, wouldnt you just store it in a var ? then change anchor min and max, assign pivot then use old pos again

[tacit lance]

I'm aware this is super niche, but I'm kinda just playing around with what I might turn into a package later.
I have a scriptable object that allows you to add elements to a list, and some data associated to each element. They are then stored in a dictionary to be accessed in runtime.

Obviously, later accessing specific things through code by indexing the dictionary by their name is super error prone, and something to avoid. In an ideal world, I would be defining the keys in an enum instead, but in the interest of making it a standalone package I'd like it to be possible to define things with little to no code.

This brings me to: is it possible to use source generators to generate an enum with variants according to the scriptable object? Is this an acceptable solution? Is there a better one?

[knotty sun]

tbh using a source generator for something this trivial is a bit of overkill

[primal raptor]

how do I make the texture random

[rigid island]

https://github.com/jensnt/TerrainHeightBlend-Shader?tab=readme-ov-file#avoid-texture-tile-repetition

[cold parrot]

the real solution is this, other techniques like noise-blending also work: https://medium.com/@jasonbooth_86226/stochastic-texturing-3c2e58d76a14

[craggy falcon]

ugh man. So i followed the guys code, completed it. One error.
I'm getting what is said to be the most common of all - "object reference not set to an instance of an object". It has prevented anything I have coded from working.

I have my InputManager(named PInputManager) where the error is supposedly. I will link the code now.

Reminder, I've followed this guy's code exactly. I don't understand what's wrong.

https://gdl.space/paradunojo.cs - PInputManager
https://gdl.space/wusevetimi.cs - PlayerMovementStats
https://gdl.space/xaciwuwoqe.cs - PlayerMovement

I hope it's understandable that I'm confused. Anything I find on this says "Find what's null, find why it's null" but I'm not too sure why it's null. Movement is brought up a few times throughout and VS isn't finding any issues. Whatever this is has completely stonewalled the rest of the code. Nothing works, I can't move the character whatsoever. Shall I just restart hours of work? Or is there a super simple solution I'm not seeing/can't find?

The comments to the tutorial do no good either. nobody else in the comments have had this issue but me

[somber nacelle]

your PInputManager is probably not attached to a GameObject that also has a PlayerInput component

[craggy falcon]

I have attached it, just now. no change

[somber nacelle]

are you reading the first error in your console?

also when you attached it, you did so outside of play mode then tried it again, right? you didn't just attach it during play mode after the error appeared and expected it to magically call Awake again, right?

[craggy falcon]

It's the one and only error on my console.

[craggy falcon]

and it's a habit of mine to stop play mode, and then test after implementing changes, or stop then start again if i've made changes while in play mode. so yes i've tried that too

[somber nacelle]

show the exact error message

also you are following a terrible tutorial if it is telling you to make everything static just to access the values from the input

[craggy falcon]

i just went for one that has the type of controls I'm after

[somber nacelle]

well it's terrible if that is how it wants you to set things up. don't abuse static just for easy referencing

[craggy falcon]

alright, i didn't know, sorry

[somber nacelle]

put this line on line 23: Debug.Assert(PlayerInput != null, $"PlayerInput is null on {name}", this);

[craggy falcon]

i was simply following the tutorial, that's it

[craggy falcon]

which script?

oh wait im stupid sorrry

blind that is

[somber nacelle]

oops i missed a t in the method name

[craggy falcon]

okay no wait it's late and i dont want to mess up any further which script am i putting this in?

[somber nacelle]

obviously the one with the error where you have a PlayerInput variable

[craggy falcon]

i was gonna finish this and go to bed like an hour ago but then ADHD kicked in realising it would just... not be working so im running on a single marshmallow from like 30 minutes ago

[craggy falcon]

alright, sorry

[somber nacelle]

don't make that everyone else's problem. if you are too unfocused or tired to comprehend instructions or debug the issue yourself, then go sleep and come back to it with a fresh mind

[craggy falcon]

i would probably be like this anyway since im a little newer to how C# works, but im also just wanting to get this done. i've been working at different styles of player movements for absolute days and this is the one im closest to finally managing since it turned out my software was out of date because my PC is due a fix.
I'm not too unfocused to comprehend instructions, im just a bit cautious in case i ruin it more since in the past that's how it's been - i'm so close to managing this. I only wanted a bit of help/an explaination, sorry if that's an issue or anything, im not a total beginner but when i've been trying to fix 1 thing for hours i kind of have to resort to help at some point

[somber nacelle]

okay well have you bothered adding the line i suggested so we can see what is going on?

[craggy falcon]

im working on it, on top of helping a friend with something

debug is a new concept to me, i'm assuming the {name} field is where i'd put the "move" in the line i got an error on in right?

it's different to the other code im used to with debugging so i'm just making sure

[somber nacelle]

you don't change anything at all, you just copy/paste it exactly as is

[craggy falcon]

it uh... almost froze my computer, wow

gdi my memory just maxed out

hang on i gotta shut some things down and try that again

[somber nacelle]

that is entirely unrelated to the Debug.Assert call

[craggy falcon]

i know, my computer just has some memory maxing issues, as i'd mentioned it's due a fix up soon

i just have to restart. common daily issue i'm having as of late

okay im gonna have to restart my computer. whole taskbar is duplicating anything i do over and over. brb

On startup. will check again shortly

[craggy falcon]

pasted on that line. Went into play mode to initiate where the error normally shows up. What's meant to happen with the debug?

[somber nacelle]

it's supposed to print another error before the one that was already happening

[craggy falcon]

That has not happened, just the error that was originally there

[somber nacelle]

show the full stack trace for the error then and screenshot the *inspector for * the object that this component is attached to

[craggy falcon]

i'll copy+repaste incase i accidentally added/removed anythig then give that a go

Okay, looking up how to find the full stack trace and it seems people have been having to manually enable it in more recent versions of Unity? Anything I find on it says that. I'm confused.
Im a little more versed in older versions of Unity but this is different than it used to be. I had to do this once before a few years back and it was easy.

How do i go about finding full stack traces for errors? (might help for the future too. im still learning)

[somber nacelle]

just click the error message and look at the extended information for it in the console

https://unity.huh.how/stack-traces

[craggy falcon]

i am clicking it. and right clicking it. nothing changes unless I double click it, where it just takes me to my code editor. it doesn't dropdown, for whatever reason

[craggy falcon]

all there is is what i screenshotted earlier

[somber nacelle]

screenshot your entire console window then

with that error message selected

[craggy falcon]

this is it. i have clicked it. in every place i can

it just repeats it below.

which doesnt change on clicking,

[somber nacelle]

and just to be clear, you did save the code and let it recompile to test with the Debug.Assert call, right?

[craggy falcon]

yes, thats when my computer froze. i re-pasted in case anything went wrong keyboard-wise, saved, and let it recompile since it didn;t get a chance.

[somber nacelle]

and you put it on line 23 like i asked and not perhaps after the line that is throwing the exception?

[craggy falcon]

just so you know I know how all this works, I know how coding software and game engines work. Unity and C# are just newer to me, and the way it debugs. I'm used to a visual novel maker, which uses the same save/manual reload/etc etc.

yes.

[craggy falcon]

i did mention.

[somber nacelle]

okay well i'm still waiting for you to show the inspector for the object with that component on it

[craggy falcon]

was only trying to sort out the first issue.

this is exact to the tutorial, too.

[somber nacelle]

i guarantee it is not because you missed a step

compare what the tutorial's Player Input component looks like with what yours looks like, you missed something

[craggy falcon]

i am beginning to realise how non-specific unity errors are, eventually i'll learn what it could be... unity seems to like to keep things a mystery and make things difficult for learners. lol

but, im willing to learn

let me check. though i did check several times, i'll check again. sometimes it's that ooone check that does it

[craggy falcon]

by component do you mean whats showing in script, or on the inspector?

[somber nacelle]

in the inspector

[craggy falcon]

ah. there we go. one thing he didn't mention

[somber nacelle]

yes, there's also a helpful message in your screenshot that should have made that fairly obvious

[craggy falcon]

i'm aware, but i was not looking at his inspector before since he just briefly swung past it and didn't mention anything needed adding

[somber nacelle]

sure but your inspector is the one with the helpful message telling you that nothing had been assigned

[craggy falcon]

again, unity's errors are pretty vague i've noticed. it takes me to a line in a script when the issue's sat in the inspector on a different app.
i think my issue is that the software I'm used to is alot more specific with it's errors and what percisely is wrong, and where it is. The engine is entirely coding a game, without all of the assets and stuff like Unity. So that's probably why I'm a little more confused with this than what I'm used to

[craggy falcon]

that is why I mentioned that it was something he hadn't mentioned. I hadn't bothered looking at my inspector because he just skimmed past it

issue is, he says nothing of what that item is, what it contains or where it's even stored...

[somber nacelle]

like i said before, it's a bad tutorial.

[craggy falcon]

i'll figure out from here im sure. thanks

well it's better than the other ones i've used - this is the only one left with a single error that i can fix

[somber nacelle]

it's teaching terrible coding practice and apparently not explaining what it is doing, so if that is somehow the only one you've found that you can follow, then perhaps start smaller

[craggy falcon]

i have tried, but again, this is the only one that's actually a) been one I'm almost able to complete and b) does what I want

I'm not making anything too serious out of this. im simply going to just learn from it - examine the working code, learn what makes it tick, what does what, etc

then i can just find other ways implementing the same kind of logic down the line as I learn more

it's how I did it with the other program anyway

[somber nacelle]

if the tutorial isn't explaining any of what it is doing, then how do you expect to learn from it? also you're learning how to do things the wrong way anyway. so it's just overall a shit tutorial that you won't learn anything useful from

but if you want to continue with shit tutorials instead of learning how to do things the proper way, you do you. i won't be helping you further

[craggy falcon]

well i am learning from it, im analysing it myself and taking bits from it

[craggy falcon]

okay, but you don't really have to be rude about it. you didn't have to help me at all but you did. I'm grateful you did, by the way. Just got to figure out this UI input module and i should be all set

[somber nacelle]

you're the one insisting on following a terrible tutorial that is teaching you incorrectly just because you can't comprehend other tutorials because you also refuse to start smaller like was suggested. there are beginner courses pinned in #💻┃code-beginner
start with those if you don't want to learn how to do things correctly

[craggy falcon]

okay, jeez. i was only practicing and fiddling around and wanted a bit of help. i'll continue fiddling around with other code and such. im not refusing anything, i want to finish what i've spent hours on before moving onto something else. i don't really see why that's an issue - everybody's different. I'm just learning, analysing and experimenting in my own way and asking for help along the way. you really don't have to be rude about that.
thank you for the suggestions.

i'll probably just find some resources and then leave the server. I don't exactly feel welcome here with the way you've said some things in a patronising manner when all i needed was a bit of help and guidance. just seems to be a progammer server thing - if one does not know all, one is not worthy of knowledge. it's been every programming server i've been in, and i have had to learn two other languages by myself without outside help like these servers because everybody just seems annoyed that im asking for help. I will find ways to learn outside of this server. It doesn't feel like a productive environment to learn after looking through some chat history. It just feels like other toxic enviroments i've found myself in. Thanks for the help, but i'll find my own way out from now own. clearly this was not the right way to go about finding help.

we were all beginners once, but it just feels like a sin in the programming community to be a beginner or someone who doesn't know every corner of something, even a little bit. its not just here but Ren'py and some HTML servers ive been in too. and not just with me. I've sat back and watched it happen. In forums and everything. Maybe i'll just stick to myself from here on out

again, thanks for the help. farewell

[somber nacelle]

if one does not know all, one is not worthy of knowledge
considering that is literally the opposite of what i'm saying, you're just bitching just to bitch at this point.
my entire point is that the resource you are currently using to learn from is teaching you incorrectly. the knowledge you gain from that will only hinder your development because it is wrong. I pointed you to resources that would actually be beneficial to you. but if you're just going to cry about being bullied because i'm pointing out that you refuse to actually learn how to do things correctly then i am absolutely blocking you. i don't help people who actively refuse to learn.

[tacit lance]

This is a stupid question, and I have no idea where to ask this, but...
When the inspector has the * to indicate unsaved changes, how do I save? I've just been selecting different things to force the inspector to switch to something else and open the dialogue to save or discard lol

Surely there's a keybind or something?

[somber nacelle]

things like asmdefs (like what is in your screenshot) have an Apply button to apply changes. also not a code question

[tacit lance]

I know, but as I said, I could not find any channels that seemed remotely relevant. If there's a better place, I'd appreciate a pointer 🙂

how do i interact with drawn tiles on a tilemap in runtime? as in stretching existing tiles like a square tool

[cosmic rain]

I don't think there are tools to modify placed tiles in the editor. If you really need that functionality, you'll need to write your own tool.

unfortunately 😔, i figured out a workaround with CellToWorld though, so at least i could get a list of the cell positions

Hello friends, I have a question about the Particle System in Games. What is the best way to create Particles for the game? Should I learn Unity Particle System or do you recommend a 3rd party program?

[stable osprey]

Anyone knows why it freaks out at angles near -90 even if I use the proper way? Here's my code:

IEnumerator AttackWithSword() {
    canAttack = false;
    Debug.Log("Started"); // Verified this only runs once

    var t = 0f; // Raise the sword up slightly -- charge the attack
    while ((t += Time.deltaTime) < chargeTime) { sword.eulerAngles = sword.eulerAngles.WithX(Mathf.LerpAngle(-90, -110, t / chargeTime)); yield return null; }

    t = 0f; // Drop the sword down in a slashing motion
    while ((t += Time.deltaTime) < dischargeTime) { sword.eulerAngles = sword.eulerAngles.WithX(Mathf.LerpAngle(-110, 15, t / dischargeTime)); yield return null; }

    t = 0f; // Recharge and bring the sword back to its original position
    while ((t += Time.deltaTime) < 0.5f) { sword.eulerAngles = sword.eulerAngles.WithX(Mathf.LerpAngle(15, -90, t / 0.5f)); yield return null; }

    canAttack = true;
}

Here's the video

I've verified that LerpAngle returns the correct angle, but the actual value in game is still janky. Same if I use ..rotation = Quaternion.Euler(..); or just use localEulerAngles

... and same if I just add 360 to all negative angles like so: Mathf.LerpAngle(360 - 90, 360 - 110, t / chargeTime)

[mossy snow]

See https://docs.unity3d.com/ScriptReference/Quaternion-eulerAngles.html. Unity does all rotations in Quaternions, so your code is flawed by assuming the angles it's reading back are consistent

[stable osprey]

I do know that, but is there something specific you're suggesting here?

[mossy snow]

don't do your rotations in world space; don't read from eulerAngles; store the initial local rotation and modify that using Quaternions (see Quaternion.AngleAxis)

[stable osprey]

I currently fixed by keeping the Y and Z components locked so it won't freak out, but I couldn't make it work with Quaternions since my animations are in EulerAngles and Quaternion.Euler didn't work

var (t, originalAngle) = (0f, sword.eulerAngles); // Raise the sword up slightly -- charge the attack
while ((t += Time.deltaTime) < chargeTime) { sword.eulerAngles = new(Mathf.LerpAngle(-90, -110, t / chargeTime), originalAngle.y, originalAngle.z); yield return null; }

t = 0f; // Drop the sword down in a slashing motion
while ((t += Time.deltaTime) < dischargeTime) { sword.eulerAngles = new(Mathf.LerpAngle(-110, 15, t / dischargeTime), originalAngle.y, originalAngle.z); yield return null; }

t = 0f; // Recharge and bring the sword back to its original position
while ((t += Time.deltaTime) < 0.5f) { sword.eulerAngles = new(Mathf.LerpAngle(15, -90, t / 0.5f), sword.eulerAngles.y, sword.eulerAngles.z); yield return null; }

[mossy snow]

that looks like the same code, just without using your extensions

[stable osprey]

the difference is that this one uses originalAngle instead of currentSwordAngle

[mossy snow]

but you're still reading from sword.eulerAngles every frame

[stable osprey]

no, that's inside a coroutine and originalAngle is initialized only at the beginning. Sorry for the weird formatting

[mossy snow]

the last while loop reads sword.eulerAngles.y and .z on each loop, so it has the potential to glitch out. And you're still doing the rotations in world space which is weird to me unless your player is absolutely locked into place with no chance of turning, moving, or getting hit

[stable osprey]

yeah that's fine I think since the object rotates.. and the reason it works is the angle.x never surpasses -90, so the quaternion can only be read one way

how would you suggest doing it with a quaternion multiplication and local space?

[mossy snow]

unless you know a lot more about how Unity has implemented its rotations than I do, that seems a weird and bad assumption to make. There are multiple ways to represent any euler rotation

[stable osprey]

would ideally like to have it work with abstract rotation/just follow the parent's rotation (the sword's rotation except the X axis), so totally interested in doing that

while ((t += Time.deltaTime) < chargeTime) {
    LookAt((target.position - transform.position).WithY(0)); // What I would have liked to work. but doesn't cause of cached angle
    sword.eulerAngles = new(Mathf.LerpAngle(-90, -110, t / chargeTime), originalAngle.y, originalAngle.z);
    yield return null;
}

hm I guess I could use .forward = like always, since the sword's end always points forward 😆
.forward never failed me and this is the first time I need this weird thing.. just thought it'd be quicker to make the animation prototype via code lol little did I know

something along the lines of Quaternion.LookRotation(desiredSwordForward, -transform.right)

🥳 thanks @mossy snow

LookAt((target.position - transform.position).WithY(0)); // Rotate towards the target
var desiredForward = Quaternion.Euler(Mathf.LerpAngle(0, -20, t / chargeTime), transform.eulerAngles.y, transform.eulerAngles.z) * Vector3.up;
sword.rotation = Quaternion.LookRotation(desiredForward, transform.right);

literally not a clue why this works and what would I have to do to change it.. just bruteforced it.. definitely need more coffee for this

[mossy snow]

you shot yourself in the foot again by reading from euler angles, and you're still doing world space rotation. Did you try rotating your test cylinder around +Y?

[stable osprey]

yeah it works on seemingly all angles 😁 Open to finding better ways though, I currently don't like the fact it takes 2 lines and still isn't really readable lol

[mossy snow]

does sword have any parent transform?

[stable osprey]

Sword's parent is the test enemy

I know my setup is doomed.. was really hoping for 5 min prototype before slapping in assets/anims but then math got the better of me

[stable osprey]

also, this in this context is the parent (TestEnemy)

Is it still not possible to configure two actions for a single-click (using the Press interaction) and a double-click (using the Multi-Tap interaction) on the same button without writing custom logic such as a coroutine? I'm using Unity Input System version 1.8.2, and have activated the flag for pre-empt actions. Independing of the settings, the single click is always notified.

[knotty sun]

do not cross post

[leaden ice]

Those interactions won't support it, no. You would need to write your own code or a custom interaction. The single click would need to wait some time before triggering to be sure it's not part of a double click

Btw the press interaction is not necessary most of the time

[stable osprey]

@mossy snow with some adjustments I made a horizontalAttack variant as well 😆

var t = 0f; // Tilt the sword backwards slightly -- charge the attack
do { AnimateSwordRotation(-50, 20, t / chargeTime); yield return null; } while ((t += Time.deltaTime) < chargeTime);

t = 0f; // Swing the sword towards the middle in a slashing motion
do { AnimateSwordRotation(20, -100, t / dischargeTime); yield return null; } while ((t += Time.deltaTime) < dischargeTime);

t = 0f; // Recharge and bring the sword back to its original position
do { AnimateSwordRotation(-100, -50, t / rechargeTime); yield return null; } while ((t += Time.deltaTime) < rechargeTime);

// Helper methods
Vector3 GetSwordAngle(float angleY) => Quaternion.Euler(0, angleY, 0) * transform.right * (rightHanded ? 1 : -1);
Quaternion GetSwordLookRotation(float angleY) => Quaternion.LookRotation(GetSwordAngle(angleY), transform.up);
void AnimateSwordRotation(float lerpMin, float lerpMax, float currentT) {
    if (!rightHanded) { lerpMin *= -1; lerpMax *= -1; }
    sword.rotation = GetSwordLookRotation(Mathf.LerpAngle(lerpMin, lerpMax, currentT));
}

not ideal since I don't have full control of the angles there but happy this works so far.

[stable osprey]

Context for anyone game-math-savvy: I'd like to animate the sword as shown here, but ideally in a way that'll allow me to work directly with local angles without relying on hacks like transform.up/right to acquire the rotations. Issue with code above is that it's a pain to include other axises in the animation. I don't really have to include them, but it'd be nice.

[knotty sun]

This spaghetti is unreadable, undebugable and unmaintainable, you are not doing yourself any favours whatsoever

[lean sail]

could you not just use real animations for this?
id also just consider using gameobjects as starting/ending placements if you cant. Hard agree with steve, this code is bad for you

the transforms would store everything directly, and lets you visualize it in inspector.

[gray mural]

I would consider creating a CustomYieldInstruction if you want your animations to be adjustable

Also, you can create an IEnumerator, if dealing with more your-like approach

private IEnumerator AnimateSwordRotation(float lerpMin, float lerpMax, float time)
{
    float t = 0f;

    yield return new WaitUntil(() =>
    {
        AnimateSwordRotation(lerpMin, lerpMax, t / time); 
        return (t += Time.deltaTime) > time;
    });   
}

yield return AnimateSwordRotation(-50, 20, chargeTime);
yield return AnimateSwordRotation(20, -100, dischargeTime);
yield return AnimateSwordRotation(-100, -50, rechargeTime);

[stable osprey]

very input

[stable osprey]

yeah initially it was supposed to be a quick & dirty placeholder until animations kick in, but at this point I don't see a reason to add animations anymore

regarding the code I kinda condensed it to post here without using up too much space, but it's kinda the code style I prefer anyway:

[gray mural]

So, you prefer repeating yourself as much as possible?

[stable osprey]

thanks! I'm more interested in the math inside the helper methods though -- making a system that could straight up animate from/to any angle without needing new code

[stable osprey]

no that response was regarding bawsi's usage of animation files

e.g.: for vertical attacks, the helper methods were these:

very slightly different than the ones for the horizontal attacks, but require different code anyway

[gray mural]

I'm talking about you repeating your code too many times, when it can be simplified to this

[stable osprey]

I'd like to turn this in a unified system that could straight up animate from/to any angle without needing new code

[stable osprey]

I hadn't responded to you yet when you asked that xD seconds later I said like your approach

-- or meant to say it lol.. sorry, I'm kinda sleep-deprived

[lean sail]

i didnt say anything about the code style. the actual logic here being done is just bad.
Consider these 2 messages that you wrote

at this point I don't see a reason to add animations anymore

Issue with code above is that it's a pain to include other axises in the animation

Adding any new feature to this is gonna be a pain in the ass. I wouldnt even continue with this solution at all

[lean sail]

Aka, the animator.

[gray mural]

I don't think animator can be used when the player chooses how to wield the sword themselves

[lean sail]

nothing being done here needs to be done this way. Id even first opt for using empty game objects as a start/end point for these "animations" before whatever this is. But it most defintitely can be done via animations or at least animation rigging

[stable osprey]

hmm when you put it like that 🤔 I'm pretty sure I have had bad exp with animator vs coroutines in game jams but that was many years ago.. I'll give the animator jam another go next jam

yeah pretty sure my issue was chaining logic & making modular animation sequences -- nevermind injecting some parts into the animation (like timed thrust in this case)

How can I make the mesh collider on the floor align

If the pivot is in the middle of the cube, then its bounds go from -0.5f to 0.5f instead of going from 0f to 1f.

[errant flame]

    [CustomEditor(typeof(GPNodeData))]
    public class GPNodeDataDrawer : Editor
    {
        public override VisualElement CreateInspectorGUI()
        {
            VisualElement defaultInspector = new VisualElement();
            InspectorElement.FillDefaultInspector(defaultInspector, serializedObject, this);
            defaultInspector.Add(new Label("asd"));
            return defaultInspector;
        }
    }

Does anyone know why i cant add extra label to defaultInspector in this block ?

[hard estuary]

Works for me. I would check namespaces to make sure your Label comes from UnityEngine.UIElements. Keep in mind that you need to use PropertyDrawer and CreatePropertyGUI instead of Editor and CreateInspectorGUI if you want your code to define how the object is drawn as property.

[errant flame]

@hard estuary I just want to make this if node type is selector than i need to add 2 selection data fields more to that block what is the easiest way to do that add property drawer on NodeData class or add custom editor or something to SO script

if i was get it i can use custom editor on only mono and so files right ?

[hard estuary]

I've noticed Editor doesn't work if it's being written as property inside another Editor/Property. I assume they call something like new PropertyField when drawing those, which is drawing properties, not editors. I haven't checked what's inside though.

[errant flame]

@hard estuary I would like to say that I am a little confused, how can I reach the goal I want to reach in the shortest way as I explained on the visual?

[hard estuary]

Try this:

    [CustomPropertyDrawer(typeof(GPNodeData))]
    public class GPNodeDataDrawer : PropertyDrawer
    {
        public override VisualElement CreatePropertyGUI(SerializedProperty property)
        {
            VisualElement defaultInspector = new VisualElement();
            InspectorElement.FillDefaultInspector(defaultInspector, property.serializedObject, this);
            defaultInspector.Add(new Label("asd"));
            return defaultInspector;
        }
    }

[errant flame]

In FillDefaultInspector last parameter want an editor instance that not accpect this i guess there is a comp err

[hard estuary]

I should've checked it before sending it. 😓 After making several attempts, don't think there is a way of drawing the default property drawer. base.CreatePropertyGUI returns null, other ways either miss something or draw everything recursively. But there is a chance I'm missing something.

I think I would just draw every property by hand. It's more work (especially if you have a lot of fields/properties), but at least it's a stable solution.

[errant flame]

i guess i move forward with custom editor window for that and draw everything one by one with my ui elements and bind them to the serialized properties other methods wont work at least i cant

yea I agree with you 😄

[tame smelt]

I built my unity application and distributed it. People are able to play the game with windows. However, with windows 7 and 8 specifically, the following error is appearing for them: DllNotFoundException: FirebaseCppApp-12_0_0.

I appreciate any help on this as I tried so many things and searched the internet but no luck

Unity is not able to find this although in the game files it does exist

[knotty sun]

which coding backend did you build with

[tame smelt]

its just Unity C#, no other scripts

with compression method of default

[knotty sun]

SO you don't know how you built your project

[tame smelt]

I am trying to understand you question

[knotty sun]

it's simple enough, Unity has several options to build your code with, which ones did you use

[tame smelt]

the default one, I tried other compressions as well

[knotty sun]

try
Project Settings->Player->Other Settings->Configuration

[tame smelt]

alright

[knotty sun]

So you are using Mono and .Net Standard 2.1 which is not supported by Windows 7 or 8

[tame smelt]

I see

what versions can support them if you don't mind me asking

[knotty sun]

.Net Framework, you can try Mono or IL2CPP

[tame smelt]

thanks

[knotty sun]

Just make sure your Firebase plugin supports .Net Framework, you may need to replace it with an OLDER version

[tame smelt]

hmm thats true thanks for that

[knotty sun]

fyi the framework version you are looking for, if required is 4.7.2

[tame smelt]

alright

[ivory pasture]

how do you draw the circle made from physics2d.overlapcircle?

[knotty sun]

there is no circle option, best you've got is Debug.DrawSphere

[ivory pasture]

wow, well that's unfortunate

thanks for the info though

[knotty sun]

yes it does and is against server rules

[haughty lance]

ah, sorry

should i delete the message or

[knotty sun]

best, yes

[haughty lance]

there we go

[ivory pasture]

what's the use of Vector2 direction in CircleCast?

[night storm]

the direction where the circle goes

[ivory pasture]

there's already Vector2 origin, float radius, where is the direction supposed to go to?

[night storm]

origin is where the circle starts. radius is how big the circle is. direction is where the circle is shot towards. distance is how far it's shot

[ivory pasture]

oh my god 🤦, thanks for the explanation

[undone leaf]

why is W moving me backwards and s moving me forwards here?

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

public class SpaceshipControl : MonoBehaviour
{
public float moveSpeed = 20f;
public float rotationSpeed = 100f;
public float mouseSensitivity = 1f; // Sensitivity for mouse look
private float pitch = 0f; // Current pitch angle
private float yaw = 0f; // Current yaw angle

void Update()
{
// Handle movement forward and backward
float moveDirection = Input.GetAxis("Vertical");
transform.Translate(Vector3.forward * moveDirection * moveSpeed * Time.deltaTime);

// Handle rotation left and right (Yaw)
float rotationDirection = Input.GetAxis("Horizontal");
transform.Rotate(Vector3.up, rotationDirection * rotationSpeed * Time.deltaTime);

// Handle pitch up and down (using E and Q)
if (Input.GetKey(KeyCode.E))
{
    transform.Rotate(Vector3.right, -rotationSpeed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.Q))
{
    transform.Rotate(Vector3.right, rotationSpeed * Time.deltaTime);
}

// Adjust speed dynamically
if (Input.GetKey(KeyCode.W))
{
    moveSpeed += 1f * Time.deltaTime; // Increase speed
}
if (Input.GetKey(KeyCode.S))
{
    moveSpeed -= 1f * Time.deltaTime; // Decrease speed
}

}
}

[hard estuary]

Have you checked if the model is rotated in the same direction as the GameObject this script is attached to?

[undone leaf]

how do I rotate it without making it face a diferent direction?

[spring creek]

That is not what they are saying

You have to make sure the model is rotated in the right direction before exporting it from blender or wherever

[undone leaf]

understood

[hard estuary]

The model is facing the right direction, if it's the same as the blue arrow here.

Moving it forward will move it in the same direction as blue (Y axis) arrow.

[undone leaf]

didn't work

it was working before, but it just kind of stopped

[hard estuary]

It's also worth noting, that the transform's Forward is a local variable.

[hard estuary]

How is your Vertical Input configured? If it includes W and S, then it will change both direction and speed. In such case, if your speed becomes a negative number, then the movement will be reversed (because negative moveDirection multiplied by negative moveSpeed will result in a positive value).

[spiral palm]

how would i press a button in code?

like emulate the press function

[spring creek]

You're going to need to provide a LOT more information.

Do you mean DETECT input?

[hard estuary]

button.OnPointerClick(new UnityEngine.EventSystems.PointerEventData(EventSystem.current));
Or use OnSubmit instead.

[spring creek]

Hmm, write a wrapper function, have the input call that function, or call it externally

Ah, a ui button

[spiral palm]

alr cool

yes

i have a render textue which im using to emulate button presses and i need to tell a button to act like it's pressed

(it's a render texture because the menu is rendered onto a 3d mesh

[stone echo]

Having some trouble with async scene loading, heres my script:

but when I check my hierarchy, GameScene is loading forever

if I remove the allowSceneActivation=false, the scene switches to GameScene immediately, but with the allowSceneActivation=false, it doesnt actually preload, does anyone have any ideas what could be causing this?

For the record, when I press PlayGame (when the async.allowSceneActivation=true is uncommented), it finishes loading the scene

but not asynchronously^

[leaden solstice]

Did you read the docs?
https://docs.unity3d.com/ScriptReference/AsyncOperation-allowSceneActivation.html

[merry stream]

im having issues with simultaneous couroutines bypassing my cooldown system. For example, two different abilites share a cooldown, this works fine when one ability is pressed within a few ms of the other, but when I hold both keys, both abilities are used at the same time, bypassing the cooldown check. I believe this might have something to do with how couroutines function? not sure. This also occurs when I activate both abilities sequentially in an update loop. It seems the cooldown isn't being checked for the 2nd ability and is applying it second time

[cosmic rain]

What does CheckCooldown do?

[cosmic rain]

Debug the longestCooldown here before returning. Then reproduce the issue and see what value it has.

[leaden solstice]

Are you trying to do Unreal GAS on Unity

[merry stream]

yessir

[merry stream]

the cooldown is being checked twice since its checked before input and after activation

[craggy oyster]

how would i setup a script to disable a component of type i dont know?

[cosmic rain]

Step through that method to see why longest duration remains 0.

[cosmic rain]

Components don't have enabled property.

[craggy oyster]

yea i kind of figured that one out XD

is there a way to do this without getting the type of the component

[cosmic rain]

You need to know the specific type that implements the enabled property. Honestly, this kind of code is pretty bad imho. What are you trying to achieve?

[craggy oyster]

i need to do this for my inventory system

i cant disable my items because i need to get references for them

so im opting to disable the components that make them an item instead

[merry stream]

yeah i don't understand why it works completely fine otherwise

[cosmic rain]

Why do you not have a reference to them?

[knotty sun]

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

[cosmic rain]

Did you step through the code?

[craggy oyster]

all items are childrens of the player

and all are disabled

until you equip them use them etc.

[cosmic rain]

That doesn't explain why you don't have a reference to them..?
Just make a list on the player and put them on the list.

Or on an inventory component if you have one.

[craggy oyster]

cant get their component if the item object is disabled

[craggy oyster]

this is what im doing

[cosmic rain]

So you do have a reference..?

[cosmic rain]

Why not add the item to the list when you add it to the player/instantiate it. Or at editing time if you only add them in the editor.

[craggy oyster]

i could do that but it would make problems in my system i havent figured out

i can sense it

[cosmic rain]

Wat, why adding a new field would make problems?

[craggy oyster]

it wouldnt be organized for one

if want to make a new item for my game with my plan i just create it and make it a child of the player

[cosmic rain]

Wdym..? How is it organized now if you even don't have a reference to your items??

[craggy oyster]

it will be once i figure that out 😅

[merry stream]

yeah, its like the second ability doesn't see the first cooldown effect yet

therefore, it allows it through and applies another identical cooldown

[cosmic rain]

If you want to avoid manually assigning them to the list, you can do that at awake/start.

[craggy oyster]

oh i just saw this

see i didnt have to do all that thnks steve

[cosmic rain]

Wdym by a "cooldown effect"?

And if it doesn't, that probably means that you don't yet apply cooldown at that point.

[merry stream]

both abilities apply the same effect which holds a cooldown tag

i dont see how thats possible since the first ability should complete beforce the second one is activated

[cosmic rain]

Then debug the timing of applying that tag and see why it doesn't happen before the second ability starts.

[merry stream]

thats why I thought it was a couroutine issue but i could be completely wrong

[cosmic rain]

It is most likely. I see that you're yielding in several places. If the cooldown is applied after the yield, it would happen on the next frame.

While the other ability is started on the same frame.

That's just an assumption though. You need to debug properly

[merry stream]

i believe you're right, ill continue debugging but could yield new WaitForEndOfFrame solve the issue?

[cosmic rain]

No, that would have the same problem, as the other ability would start right away, before the end of frame. Honestly, I don't see why you need to yield there in the first place.

[merry stream]

where?

[cosmic rain]

In TryActivate. That's the only code you shared that has yield return.

[merry stream]

they are all couroutines since some abilities are done over time

im not sure how i could avoid using them

[cosmic rain]

I don't think basing the whole system on coroutines is a good idea. But that yield return in itself is not the problem. The problem is where you apply the cooldown. You should apply it right away when the ability is passing the can activate check.

[merry stream]

ill try it, whats an alternative to achieve the same effects though?

[cosmic rain]

Finite state machine. An ability can be a class with Update method that you'd call and it would execute the over time logic if needed.

[merry stream]

so using Time.time within loops etc

[cosmic rain]

Wdym?

What loops?

[merry stream]

update loop

[cosmic rain]

Mmm... Yes, but I'm not sure we're on the same page.

I'd have something like an AbilityManager plain class instance on the player controller. And I would call it's Update method from the player controller MonoBehaviour.Update. The AbilityManager would then in turn call the update of any active ability that it manages.

[merry stream]

hm, thats completely different to how i have my whole system setup so not sure

i fixed the issue by doing this but now of course pre activate won't work since it wont wait for it to finish

[cosmic rain]

I mean, if you really need to have it the way you had(which is a bad idea imho), you could just call SetCooldown() right after the can activate check and don't need any other changes.

[merry stream]

why is it a bad idea exactly? just for the issue i was having or are there other issues that might come up down the line?

i still dont really see how your suggestion would achieve the same effect though

[cosmic rain]

The issue that you were having is a symptom that it's going in a wrong direction. Coroutines have many limitations, like them being canceled as soon as the executing object is disabled. It can also be confusing how unity chains coroutines and in what order it executes what. If you update the abilities yourself, you have full control of that and don't need to delegate anything to unity and hope that it does it correctly.

[cosmic rain]

What effect though? The only thing I've seen is a coroutine that activates the ability. I really don't see why you can't do the same with simple update logic.

[merry stream]

being able to abstract whatever preactivation the ability may use and wait for it before activating the ability itself

[cosmic rain]

Sure, super easy.

[merry stream]

but yeah i do see that you could avoid coroutines

[cosmic rain]

Just have a state machine in the ability with state like PreActivate, Updating, Ending or something and call the corresponding virtual methods.

[merry stream]

let me try it

something like this?

[cosmic rain]

No. Why does the state machine need to be in the TryActivate. It should be in Update or something. TryActivate should just make a check and set the ability state to Started/PreActivate or something. And probably set the cooldown as well.

[merry stream]

this is not a monobehaviour

https://gdl.space/koxasotufe.cs

[cosmic rain]

It doesn't need to be. I already covered the update part in details a few messages ago.

[merry stream]

i see

[cosmic rain]

PlayerController.Update => AbilityController.Update => all active abilities update.

Anyways, I'm off to sleep. Good luck.

[merry stream]

thanks

good night

Main benefits of GAS is how it works with Unreal replication system, and prediction

If you are not doing multiplayer it could be much simpler

[merry stream]

my system is not as complicated as GAS

its just to have modularity and ability to make stuff with the inspector

i do need a system like this though since my game is and APRG similar to path of exile etc

it would be a nightmare to calculate everything cleanly without it

[craggy oyster]

hey i was using scriptable objects to define data for my guns

and now that im making an inventory system i realized it doesnt work for my situation as different guns using the same scriptable object would not work

what solution is there?

[vagrant blade]

Create a different SO definition for each gun?

[craggy oyster]

you mean making a new SO for each duplicate of the gun?

[vagrant blade]

No, you create a unique SO for each unique kind of item/gun, and when you spawn that item, you use that SO definition to set it up.

[craggy oyster]

yea i know that works great but what happens when you have two of the same gun as an item

they will share each others data

[vagrant blade]

Well, you should have one item with a Quantity property set to 2

But if in your case you have unique ones, just count them. Have items store a reference to the SO they're using, so you can iterate and count.

[craggy oyster]

how would this help?

[vagrant blade]

Because you can show the item in your inventory with X2 on it? Otherwise, I don't understand what your actual issue is.

[craggy oyster]

ok

[vagrant blade]

I'm going off "I realized it doesn't work for my situation" where you don't actually describe said situation.

[craggy oyster]

omg im so stupid

i dont know why im even trying to do this

i was using SO's to handle all gun information like damage ammo and etc

so when i had two guns of the same SO they would share the ammo

[west lotus]

So real qucik queation. i have a SO that holds a list of a class and that class holds a list of other SO’s. Im trying to parse the second level so’s from a file. It works but in the inspector it says type missmatch and the data does not survive domain reload. I suppose I need to actually create the editor assets right?

[craggy oyster]

when i can just make the ammo variable local to the script

😭

[merry stream]

is there a way to use physics2d to draw a quarter circle or something similar to simulate a sword slash. Right now im just using overlap circle to take a circle some distance infront of the player but the shape is off

if not, what way is generally used

[somber nacelle]

overlap circle to get all objects in a circle around the area you'd like to check. then loop through them and use something like Vector3.Dot to determine how close they are to straight ahead of the object (or the direction of the slash) they are, if they are within some threshold apply the damage

[merry stream]

great thanks

The answer was yes I need to actually create the scriptable object assets first

[sturdy thorn]

my bad!

[spare dome]

well ofcourse the key wont follow because you dont even have a reference for the key

my suggestion is to spawn the key again on the player when in new scene

if you know they would have it

[sturdy thorn]

https://pastebin.com/tm6arKL4

[spare dome]

when loading into a new scene you can check if a player had a key or object then spawn the key again on the player, or you can just spawn key on player when entering new scene if you know that the player already has a key

[warm aspen]

For scalability I would try to make a system that stores whatever the player is carrying at the moment and loads it on the next scene with the player. Then it can work with other items and makes opportunity for other level design choices in the future

[sturdy thorn]

okay, will try

thanks!

[long scarab]

hey there, i'm making a resolution dropdown for my game's settings and was wondering if theres a simple way to filter Screen.resolutions by aspect ratio? i could make a predetermined list and call indices from there, but it would be nice to grab available refresh rate from the player's machine

[waxen jasper]

Do skyboxes work in 2D URP? I've read they don't yet there seems to be documentation on it and haven't had any luck

[lean sail]

You just make your own list if you want something specific. Screen.resolutions is just a list of supported resolutions, the width, height, and refresh rate.

[lean sail]

this is a coding channel

[leaden ice]

Write some code to filter it yourself.

[worldly hull]

i know unity default video player is AVfoundation

but somehow it seems that this built in features is encrypted and i cant access any codes regarding to this

which is normal tho, u cant access the engine source code anyway

the problem is, the video player is not working as expected in M2 silicon imac

is there an alternate way for me to change the code without using another video player?

[thick terrace]

it depends what kind of problems you're having but iirc you're not likely to be able to change any of the internal details of how it works so you might be better off looking for a 3rd-party asset

[worldly hull]

i need to change the "tolerance" of it to broken video

like at least i need to access the script file for the video player

[lucid hollow]

Do someone know why the object dont destroy itself even if the value is the right value ?

  {

      if (GameObject.FindGameObjectWithTag("MainCamera").GetComponent<Coincounter>().currentCoins == 1)
      {
          Destroy(gameObject);
      }
  }

[knotty sun]

how do you know the Destroy is being executed? Debug your code

[gray mural]

That's because the value is not the right value

[lucid hollow]

i mean i try and he is not but i dont knwo why

[gray mural]

Well, it's not the problem with the Destroy method

Also, I don't know what you mean by "i try and he is not"

[queen saffron]

Hi, is it possible to create highlight effect on Game Object Elements (Vertices and Faces) in runtime without deconstruct the object into seperate vertices and faces of each one describe a complete entity of vertex or face?
like assigning individual face to unique color

[lucid hollow]

strange because in the hiercahy in my Go the value is the same as what i want

[lucid hollow]

i want to answer to steve to said i already debug it and nothing happen

[gray mural]

If no error is thrown, either currentCoints does not equal to 1, or OnTriggerEnter2D is not called

[gray mural]

Define "nothing happen"?

[lucid hollow]

the object stay in the scene and in the game when current coins get a value of one

[lucid hollow]

thanks do you maybe know why Ontrggerenter2d will not be called ?

[gray mural]

When no collision happens

[hexed pecan]

https://unity.huh.how/physics-messages/trigger-messages-2d

[lucid hollow]

i'm stupid i don't know why y was using trigger the colison was to upgrade the current coins score but not the method to destroy it

so my problem is resolve thanks you all

[lean sail]

Not entirely sure what effect you're going for, but this should all be possible through shaders

[chilly surge]

Is there an editor tool for monitoring UnityWebRequest? Something like browser dev tool network tag, where you can inspect each request, headers, payload, response, timing, etc.

[gray mural]

Is it possible to check whether a type is serializable in Unity's Inspector? Type.IsSerializable returns True if System.SerializableAttribute is added, but despite returning true for decimal, its serialization is not supported by Unity

So, I have an Inspector for generic struct, and I want to check whether the type is serializable, because, otherwise, it throws an error in GetPropertyHeight

[late lion]

I found this, but it's not part of UnityEditor or UnityEngine, but a separate assembly I don't think you can reference in the project.
https://github.com/Unity-Technologies/UnityCsReference/blob/73c16d00a4c84d96ee9e097f5e289371a92133d3/Tools/Unity.SerializationLogic/UnitySerializationLogic.cs#L218

But you could copy the class, if you don't find any other way.

[gray mural]

Got it, thanks a lot.
I've found out that SerializedProperty.FindPropertyRelative(string) returns null when the Type is not serializable. Not the cleanest solution, but it works and is pretty simple

[chrome mural]

i have a path

a bezier path

i store the curve data into 2 List<Vector2>

List<Vector2> anchorPoints
List<Vector2> controlPoints

how do i make something move along :<

i have the formula for the bezier

but it works for 2 anchor and 2 control points!

i have many 😢

[indigo tree]

Can I see how you are getting that?

[knotty sun]

you can query a Bezier curve for any point along the curve

[chrome mural]

the yellow curve is done with Handles.DrawBezier()

altho the bezier formula looks something like this

Bezier(anchor1, anchor2, control1, control2, t)

[knotty sun]

and t is the thing you need, it's how far along the curve you are

[chrome mural]

yes

tho this are 4 curves in the photo

[knotty sun]

I meant that is what you feed in, it will return the necessary point

[chrome mural]

how do i know if the thing is on 1, 2, 3 or 4

[knotty sun]

no, there is one curve, defined by 4 points

[chrome mural]

wat

[static matrix]

how can I refer to a button in its script?
i have this code:

public void MenuNav(GameObject Activate){
        gameObject.SetActive(false);
        Activate.SetActive(true);
    }

on a script im using to hold all the functions for my buttons on the menu, but when I place it on a button and click, it turns off the buttonlogic object, not the button
how can I make it turn off the button clicked?

ofc I could just make another script

[indigo tree]

The is the UI button component, right?

[static matrix]

its one curve, and its defined by the four points

1+2+3 is just one number, defined by three numbers

[static matrix]

yes

ill just make a different script though, it'll be faster

[chrome mural]

Movement along Bezier

[indigo tree]

Is this what you want?

private Button button;```

[static matrix]

well of course I could do that, but that means creating a new variable whenever I want to make another menu screen

[indigo tree]

Is this just a data organization thing?

Trying to avoid boilerplates and such?

[static matrix]

well i'd like to avoid adding an additional script component to every single button I have that disables itself
its cool, I just opted to do that instead, really not that bad

[chrome mural]

would you help me in the thread?

[indigo tree]

Make the buttons subscribe to methods in a menu script

[static matrix]

ah
ok

ill look into that

[chrome mural]

plz help 🥹

[static matrix]

help with what????

what do you need to know

[chrome mural]

a bezier IS 4 points

ok

but i got many beziers

you see?

https://cdn.discordapp.com/attachments/763495187787677697/1275104308727255070/image.png?ex=66c4aced&is=66c35b6d&hm=1acfb8f48451181b4e416e890a3ae3af87d8bf6497dde66ed9a60f841d7b673c&

[static matrix]

you have one bezier

comprised of four (actually looks like its five) points

five is a single number
composed of five ones

[chrome mural]

wat

[knotty sun]

why do you think this?

[static matrix]

beziers (to my knowledge) look at the points and angles you've provided it, and creates a curve

[chrome mural]

because formula takes 4 points i got 15 :<

[static matrix]

bezier shouldn't take a specific number of points, it should be able to use as many as it needs?

[chrome mural]

this is 1 bezier curve

[static matrix]

correct

[chrome mural]

does it?

[spare dome]

yes thats how beziers work

[chrome mural]

so i can make a formula with as many points as i need?

ahhh

silly me

im tired

[static matrix]

im not sure
but that bezier clearly has two points
(unless the green dots are also counted as points)

[static matrix]

fair

[chrome mural]

2 anchors and 2 controls

yes

[knotty sun]

Ah, finally, the penny dropped

[vagrant blade]

At this point, you should just use Unity's spline package

[chrome mural]

i know but i wanted to take the challenge

and its just overkill for what i need also

[spare dome]

better to use spline then

[static matrix]

forumists on their way to tell people that doing anything by yourself is a terrible idea:

[spare dome]

a challenge is not what you want

[static matrix]

well you can use spline if you want
probably more powerful
but if your are more comfortable manually making the curves, then do that

[vagrant blade]

Challenging yourself is fine, as long as that's all it is. It isn't the approach if it's also being used as progress to complete something.
