[shy spruce]

but actually I think you have a point. If I use the colliders to detect the initial hit, and from there, say "only allow this if the boundaries of the inner collider are between -1.0 and 1.0 on both axes" that may work

[violet anvil]

I’ve written a script that uses the jobs system to shift around the objects and camera in my scene to create a “floating origin” - what can I use to achieve the same thing in-editor via let’s say a GUI window/button?

[queen vault]

Hello! I am making a 2d hack and slash game and I would like to have the enemy sprites to get sliced up when the sword object touches them. How can I cut a sprite during runtime into two gameObjects with their own seperate rigidbodies? I would just gib the sprites manually but I want procedural stuff.

[regal lava]

Shaders

[jolly token]

Generate mesh

[regal lava]

Oh, two gameobjects, you'd want multiple meshes yeah

but with sprites that's kinda hard to render, no?

[queen vault]

So would I make a raycast from the player and then split the hit gameObject from the hit.point and the exit point?

I don't know how to generate meshes could somebody throw me a bone?

[jolly token]

Maybe but it’s still just cut off quad, I think It’d be easiest option

[regal lava]

Honestly, probably a shader out there for it. Unless you wanna kick around the body parts, giving each part a rigid body and such.

[queen vault]

You know what.. I think I'll just create a bunch of different GameObjects and just disable the sprite bit and enable the rigidbody one idk

[regal lava]

The easiest way probably is splicing up your sprite yourself, adding a renderer for each limb. Would probably require you to animate it inside of the editor unfortunately.

Damaged limbs would detach then generate their own rigid body.

GUYS.. an Important question... I am my main scene, then I go the tutorial scene... after the tutorial is done WITHOUT ANY KIND OF ERRORS I go back to the main scene, THEN IF I ENTER THE TUTORIAL AGAIN ... I GET AN ERROR THAT A GAME OBJECT IS DESTROYED (even though it's there, and its reference hasn't been modified in anyway)... how can I solve this problem??
AND NO NONE OF THE GAME OBJECTS IN THE TUTORIAL SCENE HAS THE dontdestroyonload

[quartz stratus]

What's the exact error message you're getting?

[visual pilot]

I'm trying to figure out a way to export the Scenes In Build list that shows in the Build Settings window as part of my Unitypackage.
Since the Export Package UI does not allow me to add the list to the export, I'm thinking of going down the EditorWindow API.
It appears to be possible to construct the List<EditorBuildSettingsScene> which is part of the EditorWindow.

I'm looking at the example in the Unity Documentation on page https://docs.unity3d.com/ScriptReference/EditorBuildSettings-scenes.html
but it's unclear to me as to how I can invoke this script, and see what it does.

[obsidian glade]

not sure if it's what you mean but the [MenuItem("Window/Example Window")] attribute will add an option to open the window, under Window -> Example Window

[visual pilot]

Thanks. I can see that and understand how this works in the context of the example.
But how can I use this when I export the package and give it to a colleague?
Would they need to manually invoke Window -> Example Window to populate the list, or can I put it in an Awake() function? If it can be put into an Awake() function, which one should I put it in to ensure it's executed first?

If I keep it in OnGUI, but skip the window creation aspects of the example, I imagine that would do it?

[obsidian glade]

OnGUI is called when the window is open, you could take the button out but it would still need the window to be open

[visual pilot]

When opening a Unity Project from the Hub, what is the 1st user accessible function that is called by Unity? (Independent of Scenes)

Or would I need to (a) put it in the Awake() function of one of my scenes, and (b) always save my project (before exporting) with that scene as the active scene?

[obsidian glade]

perhaps https://docs.unity3d.com/Manual/RunningEditorCodeOnLaunch.html?

[visual pilot]

Ah ha. Thanks. I'll have a look.

Do you think what I'm proposing would work?

Actually, I have to rephrase my earlier comment.....
What is the 1st user accessible function that is run by Unity after Import Package -> Custom Package completes?

[obsidian glade]

I'm not entirely sure what you're trying to do with the scene list but I'm sure you can get something working

[visual pilot]

Thanks for taking the time.
My use case is Peer Review by students studying a course where I'm their tutor.
What the students currently do for their reviews, is to open a new empty project and import the unitypackage the other student submitted.

They then find the scene we told the students to create, load it, and then run it.
But it would be nice if this could be automated.

In our previous workshops, we've always had just one scene, so it was straight forward. But this time, there are several and the students can name them as they wish.

So I want to give the students a template script where they can list their scenes for Unity to add when the import finishes.

I found this: https://forum.unity.com/threads/how-to-run-a-setup-method-when-a-package-is-imported-updated.656470/
Maybe I can figure out a way to get it to work satisfactorily.
I don't mind if I have to give them some simple instructions on how to make it work.

@obsidian glade thanks for the links.

[obsidian glade]

I was wondering why you'd watch a package that would start meddling with the scenes, but that makes sense - the Load attribute may well work as the package is imported anyway

[visual pilot]

Load attribute?

I guess you mean InitializeOnLoadMethod.

[visual pilot]

How can I get a list of scenes in my project? (Not the just the loaded scene, but the whole collection, if I have more than one.)
Neither EditorSceneManager not SceneManager seem to be able to do this for anything but the currently loaded scene, or from the Scenes In Build list.
(Do I need to use BASH to do this?)

[sly grove]

You can only really do this:
https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager-sceneCountInBuildSettings.html
Plus
https://docs.unity3d.com/ScriptReference/SceneManagement.SceneUtility.GetScenePathByBuildIndex.html

[visual pilot]

Yea, I've looked at those.
I looked in the Scene's associated meta file, and each scene has a GUID. Thus, Unity is aware of them. How come it's not possible to find them in the assets list? Using a query like t:scene?

[hushed fable]

AssetDatabase.FindAssets("t:Scene"); Doesn't work?

[visual pilot]

I haven't tried that statement. I'll try now.

My BuildSettings list is empty, and I'm trying to populate it automatically by scanning my project.

[visual pilot]

Yes, that's returning the right number. Cheers.

Thank you!
@obsidian glade : cheers. I think it will work.

[hybrid prism]

Hi, I stuck here
I want to set for each type of writable objects delegate method to write them from theirs type to byte array

Byte here in correct way must be like typeof targetType, but its incorrect way

[regal olive]

@quartz stratus
The thing is when i am in the scene for the first time, it works right... when i am in it in the 2nd time, I WILL HAVE THE ERROR.... I thought most likely it is related to the observer pattern BUT I MADE THE SCRIPT UNSUBSCRIBE WHEN THE GAME OBJECT IS DESTROYED (which is supposed to happen when we leave the scene)...

[undone coral]

public class NetworkWriter {
 private Socket socket;
 public void Write(String value) {
  Write(Encoding.ASCII.GetBytes(value));
 }
 ...
 public void Write(byte[] value) {
  socket.Write(value);
 }
}

you can extend textstream / binarystream instead and add more types to it

you can't author a serialization framework

does that make sense?

[hybrid prism]

Understood, thanks

But message sender/receiver is a big part of library, hard to rework
Can I use reflection and opcodes to create generic statics?
Or no way to implement current architecture?
In reference author used mono.cecil and updated assembly on (after) compiling

[undone coral]

hmm

what are you trying to do?

what is the objective i mean? the big goal?

[hybrid prism]

Library mirror networking
Try to rework it to dedicated server without unity

Or better to use server build?

[undone coral]

hmm this is pretty ambitious

i am not sure how you would use the very valuable "codeweaved" (instrumented) unity components outside of unity

i can see the value generally

[jolly token]

Question: Is there any better way to initiate value on AddComponent but before the component’s Awake is called, other than turning GameObject’s active state on/off?

[hybrid prism]

Oh, thats easy, I import main unity dll with gameobject and other unity components, but they doesnt interfere

[undone coral]

it would be better to deal with the attributes and such without codeweaving

i wouldn't try to do codeweaving

so don't Emit anything

because on the server the performance benefits will not matter for now

[hybrid prism]

If I understand you correctly you can use factory (maybe with pre-setted data in repository(pattern)) or use framework like zenject. it has constructors which called (as i remember) before awake, but i'm not confident in that

[hybrid prism]

What's better?
generic static class with field Action"writer"
Or static class with property writer which search for (type writer) in dictionary?

[undone coral]

really depends how many types. ideally you just have overloaded methods

i think avoiding generics

[jolly token]

You’d still need to call AddComponent with factory. Zenject also couldn’t figure it out and just inject after Awake for AddComponent.

[undone coral]

in mirror what exactly is being written?

is it a whole component that gets passed in? a struct? or one of a finite number of types

i see they do my approach here - https://github.com/vis2k/Mirror/blob/master/Assets/Mirror/Runtime/NetworkWriterExtensions.cs

okay i see what they are doing now

unfortunately their architecture is really jank

[undone coral]

you should declare a dictionary and when a key is missing for the type by name, "codeweave" on demand (i.e. use reflection to just do the serialization)

you can deal with emitting the right stuff later

where is the code that does the actual codeweaving?

so yes you would replace that Writer<T>.Write line

[hybrid prism]

https://github.com/vis2k/Mirror/blob/3ec5ca758e7182d4b8195f8f636c8318012f3e81/Assets/Mirror/Editor/Weaver/Weaver.cs
Then
https://github.com/vis2k/Mirror/blob/6c1dc5255ef76f6dcc8875fba47f46348e1d537c/Assets/Mirror/Editor/Weaver/Processors/ReaderWriterProcessor.cs
Then creates generic statics
https://github.com/vis2k/Mirror/blob/b4d7b355fc00525800fd0fda998b0d4fb1a582cc/Assets/Mirror/Editor/Weaver/Readers.cs

[undone coral]

hmm

yeah

it's hard to see if it actually uses stuff from the unity api

maybe build the assemblies in the editor, then use stubs for UnityEngine.dll

it's so jank

[hybrid prism]

And I dont want to do this😁

[undone coral]

lol

mirror is a pretty jank library

[undone coral]

like mirror isn't even setup as a package.json package

i have a feeling it depends a lot on subtle details of unity

[maiden turtle]

yes, you manually initialize it

[hardy sentinel]

^ from the inspector

@jolly token alternatively, there's OnEnable which I believe is called before Awake

[ruby dove]

Awake is being called before OnEnable, in a per script basis. So It's Awake1 -> OnEnable1 -> Awake2 -> OnEnable2 and so on

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

[hardy sentinel]

but if what you want is to Instantiate the GameObject then initialize it before its Awake method gets called, you should reconsider what you put inside the Awake method

[maiden turtle]

no, i meant it literally

after you create it, you also initialize it

[jolly token]

You can’t with AddComponent 😌

[jolly token]

It’s also called on AddComponent

I’m building DI library and want generic consistent solution.

[hardy sentinel]

Awake is for self-initialization only.. should only have access to stuff that are already initialized from the inspector

if you want to give it an extra 'turn', only access stuff you want to be initialized inbetween on Start

[maiden turtle]

you can, you just do it

add component, then initialize

[maiden turtle]

oh

that changes the context entirely

yeah, you either have to go with a global containter used in awake, or make them implement some IInitializable which would take the containter, or use reflection

but either way, you'd either have to hack it with globals, or abstract away adding components

[undone coral]

pooling

it's true inactive game objects

but you can make a facade i think

can you overload AddComponent in an extension method?

there is a dirty way to do this 🙂

where it will get from a pool

[jolly token]

Yeah that would be fallback, but I’m researching if there is a way because it’s better to support Unity messages

[jolly token]

How can I pool a Component and attach to exiting game object?

I don’t mind having overload or alternative API to add component

[sly grove]

not possible

components cannot be detached. They live and die on a single GO

[jolly token]

exactly

But he mentioned pooling 🤔

[iron garden]

Hello everyone, not sure if this is the right channel to ask this: Is it possible to share a screenshot through a QR code with zxing? And does it work with WebGL?

[dull cipher]

Is anyone here familiar with the Bézier Path Creator?

[sly grove]

which one

[dull cipher]

https://assetstore.unity.com/packages/tools/utilities/b-zier-path-creator-136082#description

[sly grove]

what about it

[undone coral]

you cannot 😦

i think you'd be best off doing

[dull cipher]

I'm trying to add nodes to my path in script.

but every time, i have to make a new one or what?

[sly grove]

hmm i used that tool a long time ago for a project, pretty sure it has a SetNodes or something function

[dull cipher]

ok ill look into it

[sly grove]

Isn't this just Lerp?

Vector2.Lerp(uv0, uv1, intersectionValue)

[lament salmon]

nah it's like a 'remap'

he wants to remap from range 0.5...0.8 to 0...1

right?

[sly grove]

I guess are you trying to calculate 0.65 or 0.5

[sly grove]

that's inverse lerp

this is exactly what the lerp function does

[lament salmon]

I feel dumb now, I always overlooked that function, thx!

[sly grove]

i mean you're not wrong, it's a remap function, but 0-1 is a special case

[lament salmon]

well I learned something new which is awesome

[sly grove]

Remap is basically InverseLerp from the old range, then Lerp to the new range, but if the new range is 0-1, you're done after the InverseLerp

if you want to return 0.65, that's Lerp

[sly grove]

Like this

well it'd be a Vector2 like (0.65, 0.65)

[maiden turtle]

there is no other callback for initialization, and you can't detect component addition from the outside, as far as I'm aware

I'd add an extension method for game object called AddAndInitializeComponent that would take the di container as the first argument, and then just pass that around

or something similar

[dull cipher]

Do you know how to generate a new BezierPath in a script? The documentation shows this:

But I'm confused on how to use this method, if I have an array of vector3's, how would i go about generating a bezierpath?

Its probably like VectorPath path = new (What goes Here?)().GeneratePath(ArrayOfPoints, false);

[maiden turtle]

but probably don't call it just AddComponent, that could be confusing

[maiden turtle]

I think the method is not in the lib, it's given as example usage

[dull cipher]

ohhhhh

im so dumb

[dull cipher]

thanks

[regal olive]

QUESTION how do I check if I subscribed to an even already, do i have to use a bool??

[fickle obsidian]

events themselves only expose operators for registering/unregistering, on the specific class with the subscribed listener, you would need to use something like a flag(like your bool) to say "hey, I've subscribed". are you trying to limit your listener to only subscribe one time, or some other reason? context is always helpful

[regal olive]

the flag is what I meant by using a bool.. so thank you for answering!
2nd, I have an event that i need so subscribe to but will do different things depending on the team. and it might happen in the middle of the game, so I might subscribe to the event more than once

[dusty bane]

A long time ago I read somewhere that uint should be preferred over int in shaders (HLSL) for performance reasons.
Is this true?

I am searching google now and mostly finding CPU-sided info and CUDA documents saying that int is faster since it can ignore handling overflow cases, since they are undefined.

[frail ibex]

Ran into a weird issue that feels like gimbal lock but isn't today. Hoping someone here could help out:

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

public class CameraTilter : MonoBehaviour
{
    [SerializeField]
    private Transform center;
    [SerializeField]
    private Transform tiltToMatch;

    [SerializeField]
    public Transform looker;

    float lastControllerY;

    CameraController controller;

    private void Start()
    {
        controller = FindObjectOfType<CameraController>();
        lastControllerY = controller.transform.eulerAngles.y;
        controller.flipCamera = false;
    }


    void Update()
    {
        //center is the fulcrum of the staff, tiltToMatch is the top of the staff that it tracks
        Vector3 direction = tiltToMatch.position - center.position;
        direction.Normalize();
        center.up = direction;

        Debug.DrawRay(center.position, center.forward * 100, Color.red);

        Quaternion lookerRot = looker.transform.localRotation;
        float rotateBy = controller.transform.eulerAngles.y - lastControllerY;
        lookerRot *= Quaternion.AngleAxis(rotateBy, Vector3.up);
        looker.transform.localRotation = lookerRot;

        lastControllerY = controller.transform.eulerAngles.y;

    }
}

I have this script that I use to tilt the camera in the direction of a staff that pivots around a fixed point. If this staff upside down, as it nears the center, the forwards vector of the transform spins out a bunch. If I specifically negate the "direction" vector before assigning it to center.up, the problem is fixed. Problem is, I can't just do this when the staff is upside down because if the staff is attached to a vertical wall, and you go from pointing upwards to downwards, the player's view gets flipped.

This is it without flipping the direction (so it goes straight from the fulcrum to the top of the staff), it spins out near the center.

And this is it when flipped, aka the expected behavior.

--also, I don't know if this is the correct place for this, lmk if I should change to another channel

[regal olive]

Staff? I usually use a wand for this kind of stuff.

[undone coral]

the intellectually honest answer is there isn't a static recommendation for these things

[dusty bane]

@undone coral thank you. I will make a synthetic test (related to my work) if I become motivated.

[undone coral]

if i were studying performance practices i would look at hlsl shaders authored by the gpu vendors

the latest ones

and use their latest GPUs

and adopt those practices

[regal olive]

@regal olive that might have been what I saw a long time ago

(the compiler warnings like that poster)

[regal olive]

my google-fu is on point today

[dusty bane]

🙂 nice, thank you

[frail ibex]

wands are too short 😄

[regal olive]

I've experienced a very similar issue to yours. But I'm only familiar in dealing with vectors and angles. The issues in the video I guess is that quick transition when passing over the plane.

[undone coral]

that article doesn't test ampere gpus. ou can see that in turing, optimized latency is near 0 avg

imo it is probably 0 with compiler optimization turned on on ampere

so you maybe do not have to worry about this anymore on new gpus

[dusty bane]

I do remember seeing that the recent generations of Nvidia GPUs can do simultaneous integer (int/uint) and float operations, that might be another detail that helps.

[jolly token]

How about calculating preferred rotation to keep forward rather than assigning to center.up?

[chilly nymph]

GPU instancing for webgl?

[maiden turtle]

you can get the invocation list and check if you delegate is there

should work

[hardy nymph]

What is the best way to get all the data of a component in JSON format ?

I just want to send it to a server.

[flint sage]

That's a bad way to go about things, for example, you won't be able to handle gameobject/component references

[hardy nymph]

Hmm, currently the data I'm sending to the server includes all the game objects and their children and their children, so on etc - and just the names of the components. So I was thinking , for-example if someone makes changes in a component on the web it knows which gameobject it is - by the name and the name of its parents so that's how I'll be able to find that game object in unity I hope that makes sense .

This is the website

Hierarchy*

I just need a way to get all the data from a specific component and send it to the server.

[frail ibex]

Hey thank you for responding, I'm not sure I get your solution. Just to be sure the problem is clear, I went ahead and made a more abstracted out demo.

All 3 of them have their transform.up vectors set to the direction towards their target.

The first one just does that, but spins out if the target is below the pivot point.

The second instead gets set to the inverse of the direction, so it works well below the pivot but spins out above it.

The third is my closest solution, where it swaps to the regular direction when the target is above the pivot, and swaps to the inverse when it's below, but it isn't continuous, so it doesn't work. My ideal solution is one exactly like the third, but without that jump when the target goes above/below the pivot.

For the life of me I can't figure it out.

    void Update()
    {
        Vector3 dir = (target.position - transform.position).normalized;
        if (TrackOppositeDirection)
            dir *= -1;
        else if (SwitchDirection && dir.y < 0)
            dir *= -1;
        transform.up = dir;
    }

And this is the code each is running

[frail ibex]

Nevermind, figured it out. Instead of transform.up = dir; doing

this.transform.rotation = Quaternion.FromToRotation(this.transform.up, dir) * this.transform.rotation;

Fixes it

[regal olive]

I see.. Thank you

[snow flint]

hi, wondering if someone could advise me on the best approach for this

i have a druid unit in my game actions this unit will have will allow them to transform into a bear or cat or whatever, how should i handle the changing of the unit model at runetime? the unit models will be read in file a supplied path from a json file

i dont think instantiating a new model would be the best way>? but its the only way i can think of

[maiden turtle]

why not?

[tidal solstice]

instantiating a new model might save you a lot of headache down the line.

if your bear/cat/whatever models have different animation rigs, then you would not only have to change the mesh, but also tamper with your animator's settings too. on top of that, if you want to be able to equip items (armor, accessories like hats, etc.) on any form, then you need to have separate sockets for each model your druid unit uses.

imo you reduce coding overhead by just having a prefab you can load with your desired mesh, animator, and sockets.

ofc, if your unit can change forms a lot, then performance might be an issue, so what you can do is pool the models and reuse them as needed.

[snow flint]

I though instantiating a new model at run time would be expensive, i thought maybe some sort of pooling and enabling and disabling when neeeded

ah nice, ok im thinking about it the right way then, thank you guys as always

[distant pivot]

Hi, I'm having issues finding the right rotation/quarternion for adding meshes above other meshes :
the top ones are "fine" but i need to rotate my trees (and other stuff) according the plane. Except the planes have a 0,0,0,0 rotation, i need to find the rotation in code
Here's the code I'm using to create the trees :

    public void AddSomePrefabs(List<GameObject> forestPrefabs, Transform plane)
    {
        Collider collider = this.GetComponent<Collider>();
        int random = Random.Range(0, 5);
        if (forestPrefabs.Count > 0)
        {
            for (int i = 0; i < random; i++)
            {
                int index = Random.Range(0, forestPrefabs.Count);

                Vector3 randomPositionOnMesh = new Vector3(
                         UnityEngine.Random.Range(collider.bounds.min.x + margin, collider.bounds.max.x - margin),
                         collider.bounds.center.y,
                         UnityEngine.Random.Range(collider.bounds.min.z + margin, collider.bounds.max.z - margin)
                     );
                GameObject prefab = Instantiate(forestPrefabs[index], randomPositionOnMesh, plane.rotation);
                prefab.transform.SetParent(plane);
            }
        }
    }

Ask in #🔀┃art-asset-workflow

[rugged radish]

you have the up vectors for all the objects (tile center - planet center) and you have Quaternion.FromToRotation

[distant pivot]

thanks, i'll look into it

[livid kraken]

I have a q. Can Time.time differ between Update and LateUpdate ?

[somber swift]

I think unity updates the Time.time only once every frame, why not try yourself?

You can use Time.realtimeSinceStartup if you need more accurate time

[jolly token]

Alright. Thank you for detailed video. Can you tell me what is looker, center, tiltToMatch and controller in your code? I think it might be problem that you’re using eulerAngle converted from Quaternion

[livid kraken]

I am trying it and it does not differ. The thigs is I am looking at "Someone elses code" spooky I know. And there is this really strange check, where he stores the current time in Update and if it does not match up he does a early bail in LateUpdate, but for the life of me I cant think of a scenario where this will even fire. Perhaps its to guard vs a hude lag spike ikd

[somber swift]

That sounds weird. Even in huge lag spike, I dont think unity will update the timer between update and lateupdate.

[livid kraken]

exactly, so I'm wondering why the f did he do it in the first place

I mean its a rather complicated system involving procedural animation and motion matching so it's not like it was written by some noob

[somber swift]

Maybe there is a chance that the object is disabled between Update and LateUpdate call and then enabled few frames later after Update so only LateUpdate would be called and the point of the check would be to make sure it is the same frame as earlier, although it would make more sense to use Time.frameCount or simply toggle a bool when disabling the object or something like that. I'm not aware of the way Unity calls Update and LateUpdate functions so I'm not even sure if this would be technically possible but that's the only thing I could imagine

[regal olive]

Hello, is there a way to run a unity game without popping a window? For context my game needs to run and produce frames without any window being open.

I'm trying to convert some thread-safe Java code into C# (I need to replicate some functions of a back-end java server a Unity game needs to interface with). The code in question is a synchronized hash table access. In java, it looks like this, for put, get, and remove:

public void removePerceivedPlayer(PerceivedPlayer perception)
{
  perceivedPlayerMap[perception.getEntityId()]
  synchronized(lock)
  {
    perceivedPlayerMap.Remove(string.valueOf(perception.getEntityId()));
  }
}

I've created a ConcurrentDictionary to hold this data on the C# end of this, but I'm not sure how to actually synchronize it. Is it as simple as just doing concurrentDictionary[x] = y? No need for any fancy other stuff, C# just handles it? Or do I need to do something else?

[undone coral]

object perceivedPlayerMapLock = new();
public void RemovePerceivedPlayer(PerceivedPlayer perception)
{
  lock(perceivedPlayerMapLock)
  {
    perceivedPlayerMap.Remove(perception.getEntityId().ToString());
  }
}

[plain abyss]

Okay, so, even with a ConcurrentDictionary, I still need to use the lock syntax?

Can do

[undone coral]

uh

you can just use a regular dictionary

concurrent dictionary is not a synchronized map

[plain abyss]

Okay, so, I'll switch back to normal dict and do this lock thing instead

[undone coral]

it is thread safe, but that doesn't mean it's correct, if that makes sense

i think if your java code uses synchronized

like if it does multiple things to a dictinoary

in a method call

you still want to use lock in your C# code

[plain abyss]

It's weird but despite the fact that I am generally bad at Java I understand java threading much better than I understand C# threading, because most of my C# is Unity code which is single threaded

[jolly token]

So ConcurrentDictionary is concurrent but not transactional

[undone coral]

that is correct

[jolly token]

If you need transaction like check if it contains key A then get A
Other thread could've removed A between contains and getter for example
That case you would want to use lock

[undone coral]

synchronized isn't transactional either

it's not atomic either

i'm not sure what the right word is

"only one block can be executing per thing used as an argument to synchronized / lock"

[jolly token]

I think I heard ConcurrentDictionary also allocates on many operations

[icy aspen]

Hi guys, I have a question, is there a way to open up the mobile keyboard on both android and ios with some code? If not, how can i make one and let it work?

[undone coral]

concurrentdictionary and concurrenthashmap are meant to be used for caching

[jolly token]

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

[icy aspen]

thanks

[icy aspen]

it's not working... i used this code:

[devout hare]

What are you actually trying to do? If the game has an input field where you expect the player to type something, it'll pop up the virtual keyboard automatically when it gets focus

[icy aspen]

no it doesnt, maybe its because im using webgl idk

[devout hare]

If it doesn't do that then you can't fix it by trying to open the keyboard manually

mobile input fields work in Unity 2022 onwards

[icy aspen]

can u explain more please?

[devout hare]

I ... don't know how

What version of Unity are you using?

[brisk pasture]

you mention webgl

it might not be a thing for webgl

since that mode was designed for a browser and a physical keyboard. so you might have to find a way to call it from js

[devout hare]

It is, starting from Unity 2022

[livid kraken]

Doc its a 2k line monster sharing the code wont help us understand haha

[coarse charm]

hello, I have a character with animations, it has idle walk run etc animation, I want to add a weapon like a sword or a gun, but I want it to move along with the current animation, how could I achieve that?

[sly grove]

just child it to the appropriate bone in your character's rig. This is not a code question, it's an #🏃┃animation question

[coarse charm]

aight ill ask there, I did child it to the hand bone, but it remains static not following the bone movement but rather the space position

thanks

[undone coral]

lol

is it the matchmoving asset?

i don't think LateUpdate's Time.time is different than Update's

but i feel like the Time Illusion in unity is fluid

there is no static advice about time

[icy aspen]

im now trying it with the 2022 beta release

but i already tried it with the stable 2022 release

is there anything in particular i have to do to let this work for webgl @devout hare

[meager pivot]

Now, I'm designing a game system that allows players to I can design my own magic and I want to know if I can convert string from json or etc and use it to work in Script or not. The way we have designed it, the system will need 1 is the function of magic 2. To use this magic, I press E to use the skill and string that is in the json file in the Parameter "How Controll" to work in the script accordingly. picture

My use of language might be weird. I'm not good at it. 😢

[brisk pasture]

yeah there are a few json libraries you can use with Unity

https://docs.unity3d.com/Packages/com.unity.nuget.newtonsoft-json@3.0/manual/index.html

[maiden turtle]

I don't think you can do this, not in unity

like compiling and running a string

[brisk pasture]

you cant compile and run a string, but you can read in data from a json string and use it

[maiden turtle]

you should be able to load a dll if you're not doing an iltocpp build

[brisk pasture]

still would no recommend that

like would go for a data oriented design for this

or implement something like a lua scripting engine or ironpython into your game

[maiden turtle]

well, loading assemblies dynamically is good for modding

and both lua and python suck

compared to c sharp

[brisk pasture]

loading assemblies is good for modding, but not the best if you want to do stuff in game

and lua sucks for making a whole game yes, but its a more simple syntax that is nice for if you game allows in game scripting of events

[maiden turtle]

you mean the fact that the import process would be harder?

for a regular user

[brisk pasture]

import process, but also if its for a mechanic and not full on modding you do not want to expose everything

[maiden turtle]

it's less work for the dev, and more possibilities for the modder

yes, it is slightly harder to export-import, but with proper tooling it can be made easy

and given the fact that lua sucks, I'd go for assemblies any day of the week

[undone coral]

you are on the start of a very long journey. you can look how spellsource and xmage do this

they are both open source

[compact matrix]

i am so close to building this server

anyone know how to fix this?

[undone coral]

add the appropriate editor module in the hub

[compact matrix]

thanks

[rugged oar]

do yall have any idea why this isn't working? Is it because it's an awake?

[jolly token]

Probably so. I think ActiveScene changes after Awake called?

[brisk pasture]

it also might make more sense to not have a condition to check scene

could just have a script in the GameOver scene that calls for things to be locked on Start

no need to check the scene name, if you know it will only invoke start if in that scene

[rugged oar]

okay it's weird, it is like resolving. I put in debug logs to print the visiblity and and the lockmode but neither of them work

or wait

it says lockmode none and and visible. true which is what I want

but it isn't looking very true

[obtuse flume]

Suppose I need the following functionality:

• An array of type GameEffect that is displayed in the inspector
• Many implementations of GameEffect with their own logic and fields to be put into this array
• A way to display these fields in the editor, not requiring me to re-write the custom editor script upon adding new fields
• Preferably not using ScriptableObjects to avoid 20 CreateAssetMenu entries and clutter in the game files (I hear there might be a way around that?)

Here is what I am trying, but I can't help but feel it may be overcomplicating things:

• GameEffect is just a plain old serializable classes
• I use a custom editor and reflection to display all the fields and keep them editable

It feels like I'm almost re-inventing the wheel by writing my own editor that displays non-inherited fields, but I don't know how else to do it:

                foreach (var field in gameEffect.GetType().GetFields())
                {
                    switch (Type.GetTypeCode(field.FieldType))
                    {
                        case TypeCode.Int32:
                            field.SetValue(gameEffect, EditorGUILayout.IntField(field.Name, (int)field.GetValue(gameEffect)));
                            break;
                        case TypeCode.Boolean:
                            field.SetValue(gameEffect, EditorGUILayout.Toggle(field.Name, (bool)field.GetValue(gameEffect)));
                            break;
                        ...
                    }
                }

[hardy sentinel]

well for one your inspector looks neat!

for two -- you didn't reinvent the wheel, you invented rendering polymorphic lists in Unity Inspector

[brisk pasture]

there is a nicer syntax for that switch as well

[hardy sentinel]

but if you're into this kind of stuff, you can buy the Odin Inspector asset and just keep a [OdinSerialize, ShowInInspector] List<GameEffect> gameEffects;
-- which you can populate from the inspector with plain C# objects that derive from GameEffect

[brisk pasture]

you can switch directly on a base type, and have all the cases just be the wanted extending type + a var to save it into if that branhc is choosen

[regal lava]

It's unfortunate that Unity's support for custom inspectors is pretty disappointing. I'll eventually automate my assetmenu when I get tired of editing it. Odin is nice though.

[hardy sentinel]

you realize Odin was build on Unity right? 😆

Unity's support for custom inspectors is excellent imo!

just yeah not as high level as it could be for a lot of stuff -- especially when it comes to serialization of non-UnityEngine.Object objects

[obtuse flume]

At the very least it is a good practice exercise to make my own editors 🤷

[hardy sentinel]

oh you don't have to stop making editors if you use odin 😛
https://cdn.discordapp.com/attachments/789984871413448754/790251142872825856/2020-12-20_18-14-13.mp4

and this is plain Unity iirc (no Odin): https://www.youtube.com/watch?v=PRcPX7__k_4

[obtuse flume]

Wow it lets you customize so much those are clean

[jolly token]

Odin charges too much if you are in company with revenue, also serialize your object with custom logic which makes it hard to remove

[brisk pasture]

alot of it is pretty easy stuff to recreate if needed per case

[jolly token]

Yes many of them features have open source version

[brisk pasture]

at work projects are long lived enough we do a lot of per project tools

but also got packages with stuff we carry project to project

[hardy sentinel]

@obtuse flume I wonder how hard it'd be to turn that small part with reflection & temp serializing into something reusable

... like a serializer/inspector that supports polymorphic lists 😆

also you probably don't need the types to be scriptable objects at this point (?)

[obtuse flume]

Yea definitely not

[hardy sentinel]

so theoretically could use on any polymorphic list

[obtuse flume]

yeah

you just need to add [SerializedReference] attribute to the list so unity doesn't revert the objects to their generic type when serializing

[regal olive]

so i have a problem, when i reload my scene, my update function doesnt work in one of my scripts.. i did testing and the script is running but only the "Start" method runs not the rest any idea why?

[sly grove]

Update won't run if the object is destroyed or disabled

[regal olive]

my object isnt in the scene to begin with

[sly grove]

Doesn't matter

[regal olive]

the script spawns the objects in slowly from the top of the screen

[sly grove]

The spawner isn't in the scene?

[regal olive]

The spawner is

[sly grove]

Isn't that what you're asking about

Or something else

You shared the spawner script

[regal olive]

well the spawner just isnt spawning

but it is in the scene when it reloads

[sly grove]

The spawner itself isn't spawning? Or it's not spawning the other objects?

[regal olive]

its not spawning other objects

[sly grove]

Well is update running or no?

Use debug.log

[regal olive]

let me see

[sly grove]

I'd guess perhaps you've set time scale to 0?

[regal olive]

well i have pause menu

and it does that

[sly grove]

So are you doing that?

[regal olive]

but it un pauses when you press esc

[sly grove]

Because that will make this not work if time scale is 0

Anyway do the log thing

That's step 1

[regal olive]

Yea the logs are going

so the update function is working

weird

[sly grove]

Print the timescale

[regal olive]

Okay

lmaooo

fixed

yea it was the timescale

ty i honestly wouldve never thought of that

[ruby viper]

While not an advanced coding problem per se, I'm not a C# beginner and am in complete incomprehension of what's happening with my code. Maybe a C# master can help?
These two screenshots are taken one "step over" apart, with the actual current values being displayed.
How can Mathf.Clamp(130 + 0.004, 0, 130) result in 100.004 ?
For the record, before we step into this function, the previous value of this.internalLife was indeed 100. So it's like the actual computation is Mathf.Clamp(100 + 0.004, 0, 130).
Which doesn't make sense since at this point this.internalLife is 130 🤔

(this is a piece of code that handles life regeneration, and this issue arises when the stats of the entity change the maximum life)

[orchid marsh]

I'm assuming max life was set to 100 and changed back to 130 sometime before the next step.

[regal olive]

Any clean and easy ways to implement method composition in C#? I have a set of methods that have several steps, each of which can be fulfilled in different ways through different code. I have a set of final classes which use these methods in very specific and custom ways.
Is there any easy way to implement such methods that are composed through a set of steps, which can vary between said methods?

[regal lava]

If this is a single hierarchy, then you'd just virtualize your methods and override them when necessary, using the Base keyword if you need previous functionalities.

[regal olive]

Problem is that I would have to override the entire method. I wish to override only a very specific, logically united block of code in the method.

Making that block of code its own method, and overriding that, is one way to solve the problem, but that results in messy parameters, return types and also some logic inbetween these logic steps (as I'm now splitting one method, which has all types of fields & return-checks), which I'm wondering if could be removed by syntaxis with some feature of C#.

If such feature exists.

[orchid marsh]

Have a delegate and process that for ambiguous morphing behaviors?

[regal olive]

Furthermore, I would like this to be specifically by the pattern of composition, as there is another inheritance line that messes with it. Say A goes to B and C, and B goes to B1 and B2, and C goes to C1 and C2. If B2 and C2 now have similar code, I could not shorten it through inheritance, since multiple inheritance in C# does not exist. I could with composition, though (by B2 and C2 creating the same object as a "logic-executor")

[orchid marsh]

Assuming you're only needing to inject some statements that needs to vary.

[regal olive]

May you please elaborate?

I'm not experienced with delegates.

[orchid marsh]

You'll probably want to look em up. It's a pretty broad topic.

[regal olive]

Alright.

Ah, I see what they are. That would be one solution, but I don't know how different it is from making an abstract empty class for every single logic step (which consists of between 4-8 lines) of every single method (around 3 of them), then extending from those to the specific variations of behaviour in that logic step, and then making an object of the wished behaviour in the code. It is composition, but not encompassing properties or methods, but (together) concrete execution of a method, hence composition in methods.

With delegates, I would simply pass the wished delegate in the method execution.

If it's not possible to pass pre-defined delegates, this would actually make it worse, as then I would have to duplicate code.

The reason I wouldn't like the above implementation is because I would have to make 8-12 classes, as there are 2 of such composable methods, each with around 4-6 logical steps. Think of the naming as well of these classes. "methodA-StepB-ImplementationC". Or rather, something like "addItem-InitialCheck-FullCheck" (the dashes are actually underscores in this case. Discord would format stupidity if I used them)

Am I doing something terribly stupid or is this (composable methods) a legit C# design pattern?

All of this is for shortening and preventing duplicated code as much as possible, btw.

[regal lava]

Probably want to write a mock up before attempting it. Large classes aren't usually what you should be aiming for even though the general idea of OOP is of that. Interfaces implementations are also a great way to lessen the amount of work you'd need to do implementing similar logics for different classes.

[regal olive]

What I'm thinking is something like this:

abstract class BaseTest {

  public void composableMethod(int input) {
    if (!legalInput(input)) { return; }
    int result = calculateResult(input)
    postCalculateResult();
  }

  protected abstract bool legalInput(int input);
  protected abstract int calculateResult(int input);
  protected abstract void postCalculateResult();

}

class TestA : BaseTest {
  protected override bool legalInput(int input) {
    return input > 0;
  }

  protected override int calculateResult(int input) {
    input++;
  }

  protected override void postCalculateResult() {
    Debug.Log("Incremented input!");
  }
}

class TestAAlternate : TestA {

  protected override int calculateResult(int input) {
    input--;
  }

  protected override void postCalculateResult() {
    Debug.Log("Decremented input!");
  }

}

Here we see a class BaseTest which sets the structure for the other classes. TestA and TestAAlternate have thus the public method composableMethod(), which can be called. This method is executed in different ways at precise steps, as shown by the extension and overriding of the certain logic steps in it, such as legalInput(), which checks the parameters, and postCalculateResult(), which can execute something after the main behaviour.

Keep in mind, in my case these methods are much bigger and more complex. In this case, you could simply write some duplicate code, but in my case, it's not feasible.

Notice how TestAAlternate doesn't need to change legalInput(), and thanks to this pattern, it simply derives from the previous implementation.

[ripe kite]

Hey everyone! I have a task - to make a level system for our game. The levels should have following features:

1. Should have metadata, containing its displayed name, description, number of players and supported game modes.
2. Should support streaming
3. Preferably be a single file

I know how to do this by splitting the level into scene data and metadata, but is there a way to make it a single file? Metadata should be retrievable without loading the level whole.

Did anyone ever try to make something like this?

[regal olive]

abstract class BaseTest {

  public void composableMethod(int input) {
    if (!legalInput(input)) { return; }
    int result = calculateResult(input)
    postCalculateResult();
  }

  protected abstract bool legalInput(int input);
  protected abstract int calculateResult(int input);
  protected abstract void postCalculateResult();

}
//Here are the component classes
class LegalInputChecker {
  public bool execute(int input) {
    return input > 0;
  }
}

class InputIncrementer {
  public int execute(int input) {
    input++; //I know this won't work and I should use wrappers instead
  }
}

class InputDecrementer {
  public int execute(int input) {
    input--; //I know this won't work and I should use wrappers instead
  }
}

class IncrementAcknowledger {
  public void execute() {
    Debug.Log("Incremented input!");
  }
}

class DecrementAcknowledger {
  public void execute() {
    Debug.Log("Decremented input!");
  }
}

//Here implementations with a fully composed method through creating //behaviour objects that handle certain logic step.
class TestA : BaseTest {
  protected override bool legalInput(int input) {
    return new LegalInputChecker().execute(input);
  }

  protected override int calculateResult(int input) {
    return new InputIncrementer().execute(input);
  }

  protected override void postCalculateResult() {
    return new IncrementAcknowledger.execute();
  }
}

class TestB : TestBase {

  protected override bool legalInput(int input) {
    return new LegalInputChecker().execute(input);
  }

  protected override int calculateResult(int input) {
    return new InputDecrementer().execute(input);
  }

  protected override void postCalculateResult() {
    return new DecrementAcknowledger.execute();
  }

}

Here we have an implementation of my idea using component classes. This way inheritance can be cleared for something else, while no behavioural code is duplicated (the wished behaviour is accomplished by instantiating the correct component class)

Major benefit is simpler hierarchy and also it doesn't occupy inheritance of the Test classes.

Cons are worse performance due to creation of the component classes (they hold no values though, so little memory usage), and also a ton of component classes for every implementation of every logical step of every composable method.

My main question now is:

Am I doing something terribly stupid or is this (composite methods) a legit C# design pattern?

[maiden turtle]

you're essentially doing a strategy pattern

a totally legit thing

read gof design patterns for some more context

to eliminate the memory usage, make them into singletons (they have no state anyway)

or use delegates if a lot of classes feel hairy

you don't need wrappers btw, pass the int by ref

or reassign the returned value

[maiden turtle]

is metadata key value pairs or just a struct? wdym exactly by streaming?

a single file essentially means you are limited to a single scriptable object type or monobehavior type

[ripe kite]

A struct

[maiden turtle]

other then that, you can stick your whole game in a single file, for all the compiler cares

[ripe kite]

I'm currently trying to embed scene into a scriptable object. That would probably be enough.

[maiden turtle]

AssetReference?

have that as one of the fields of the metadata

are the levels known in advance?

[ripe kite]

AssetDatabase.AddObjectToAsset - i'm trying to do this.

[maiden turtle]

ah no I don't think that would work with scenes

[ripe kite]

Yup. They will be created and edited in the unity editor.

[maiden turtle]

or prefabs even

[ripe kite]

Hm... Ok. Metadata fields then. But I couldn't find good examples of working with the metadata fields. Could you point me at some examples?

[maiden turtle]

you need a scriptable objects with an array of those structs, make that hold an AssetReference to the scene. Or get the scene by loading it by index

metadata files?

just make a scriptable object with all the info

or an object for each of the levels, if you're felling like it

I'd just stick it in an array though

I don't know what you're referring to when you say metadata files

In unity, metadata files are just guids of the asset

(most of the time)

or do you want to write to those?

[ripe kite]

I've meant .meta file. I feel, that's not what you've meant 😄

[maiden turtle]

you want to store data there?

I'm pretty sure that data is only for the editor

and I've never seen people write to it

some built-in unity things do save data there

but other than that, I haven't seen it be used for anything besides ids

[ripe kite]

Well, I just don't want to clutter the editor with additional files. I wanted my level designers to be able to create a file, edit/delete/rename/copy the files and make the editor do everything else. I'll try storing the metadata in the separate scriptable object, and write a custom inspector for a scene file that will edit corresponding SO. Is it possible?

[maiden turtle]

I don't think you'd be able to do a scene inspector, you could do a window that would find the so of the current scene

[maiden turtle]

you make a function that takes a bunch of delegates as inputs, and then just call them in the correct order

but yeah, I've mentioned strategy already

[proud sable]

Anyone know a way to access vertices on a Mesh when it's not read/write enabled? Tried using Mesh.AcquireReadOnlyMeshData(mesh) and accessing the NativeArray outputs but it still cries about the mesh being readonly?

This is for modded content which I can't manually enable read/write on

I can use unsafe accessor if the only way is directly accessing memory to yoink them

[light falcon]

I am getting these errors

            inputActions.Disable();
            actionMap.Enable();
        }

this is my inputmanager. I have no idea what the error is complaining about....

I should note that I'm creating the input manager using [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.AfterSceneLoad)]

[regal lava]

Invoke new() in start

[jolly token]

Probably the static field initializer is the problem.

I'm currently trying to embed scene into a scriptable object. That would probably be enough.
you've figured out how to take the two worst ideas and compound them into something so bad, it is going to be legendary on this server

[undone coral]

this is fine

[ruby viper]

So in case you care, this was actually a bug with C# IL. I'm not exactly sure what causes it, but binding the property's result to a temporary actually fixes the variable. Here is the side-by-side IL. This is a bit nuts and I've never seen that before but... Whatever I guess

[undone coral]

it sounds like your implementation of internalLife is buggy

what is it?

also possibly MaxLife

i think it's MaxLife that is buggy

i don't see a bug in the IL

those are just two different methods

[ruby viper]

internalLife is a float, MaxLife is a property that returns a float (and doesn't mutate internalLife)

Those aren't two different methods, basically the buggy version is:

this.internalLife = Mathf.Clamp(this.internalLife + amount, 0, this.MaxLife);

And the non-buggy version is:

var maxLife = this.MaxLife;
this.internalLife = Mathf.Clamp(this.internalLife + amount, 0, maxLife);

As you can see in the IL, the only real difference is that MaxLife is called earlier. But I'm not too versed in reading IL so there might be something else. Either way it definitely looks like a language issue (and I'm not kidding, the code above 100% fixes the issue).

[undone coral]

well you didn't share the code for MaxLife

so that's probably it

i don't know what else to say

uh, looks like a PEBKAC issue to me. Look at your original screenshot. InternalLife is 100, MaxLife is 130, you add 0.0043566, so what is result of:
Mathf.Clamp(100 + 0.0043566, 0f, 130)? 100.0043566 is the correct output, so it all looks right to me

[undone coral]

yeah

looks right to me

i mean there's obviously nothing wrong with the code

@ruby viper so uh, you know, i don't know why you thought there was an issue

[ruby viper]

I take it you guys never actually used a debugger, but the two screenshots are one step apart, in the order in which they're posted.

[gray pulsar]

it seems like the line where internalLife shows a value of 130 in the debugger is the debugger showing an unreliable value

[long ivy]

or the MaxLife property is modifying internalLife

[undone coral]

well why not post the source for maxlife

there's no bug in the IL or in the code

i figure you wanna get to the bottom of this

[gray pulsar]

ah, yeah, if the setter for MaxLife called AddLife before assigning the new value you'd get this

[ruby viper]

I wrote that MaxLife doesn't mutate internalLife

[undone coral]

lol

[ruby viper]

There is no setter for MaxLife

I can post the source code tomorrow, sure thing.

[obsidian glade]

certainly a bold move to claim a language/compiler fault with basic usage of properties and clamp

[ruby viper]

How else would you explain that the "fix" simply is to bind the value to a variable before using it? C# is such a high level language that it doesn't even make more sense.

This isn't like there are race conditions or anything considering this is running in "regular" Unity.

[long ivy]

MaxLife is actually a method running extra code. It doesn't need to have a setter to mutate anything, and your debugger output indicates it (or something it calls/uses) is modifying the value of internalLife. The output of Mathf.Clamp is within range, so that's definitely not the issue. That leaves your MaxLife call

[ruby viper]

I'm posting the code tomorrow for sure!

[obsidian glade]

that, or as Tachyon11 suggested, something unreliable in the values being retrieved by the debugger

[jolly token]

Is it actual value of variable? Did you log it? Or you stepped out of the method and the value is not valid anymore hence the color is red.

[sage radish]

I know you said you've given up, but the reason you can't use any of these methods is because a read only mesh isn't stored anywhere in RAM, only in GPU memory. You should be able to read the data directly from the GPU if you're using Unity 2021.2+ with the Mesh.GetVertexBuffer() method.

[undone coral]

there is nothing wrong with the code or IL nepho posted

it is likely the user is misreading the debugger or there is a glitch in MaxLife

[inland prairie]

Is there a way to register to a SKinnedMeshRenderer material change? I have a bug in which a material is being changed by something and no where in my code that is being done so I want to put a breakpoint and see who is changing it, however I dont have idea how to observe that change

[undone coral]

what do you mean, the material is being changed by something?

it still has material and materials (SetMaterial and SetMaterials) fields, you can set breakpoints on those

but that's probably not your issue

[inland prairie]

thx but nope that is not the issue. SkinnedMeshRenderer's materials array is being changed by some script or something

I'm tryig to figure out which is that something, problem is that I cannot create a breakpoint on the value of materials being changed so I could observe who is setting them

[undone coral]

you can

why do you say you can't

in Rider at least i can

you can also "find usages"

[inland prairie]

well, thing is that SKinnedMeshRenderer is a class by Unity

[undone coral]

https://www.jetbrains.com/help/rider/Debugging_External_Code.html

it lets you set breakpoints in decompiled code

i do it all the time

would that be helpful?

[inland prairie]

oh really

lt me try

but

let me check something first

it might be possible

this is in the Decompiled code of a Renderer

yeah, that works nicely

@undone coral thanks!

[drowsy falcon]

Anyone have a good 2D top-view pathfinding algorithm? I have implemented A* for my project and its been working just fine, but they look very unrealistic and static

by unrealistic and static I mean a group of characters moving in a straight line, taking the exactly same path + they look like a single character without collision when moving all together

most internet resources are either side-view or nav mesh thing that applies to a 3d project

[gray pulsar]

pathfinding is not the problem you're trying to solve. You should look into steering behaviors. You use them layered on top of a pathfinding algorithm to control the details of how characters move (ie spreading out, clumping up, queuing, etc etc) while still having the pathfinding control the overall path they take

[regal lava]

A* probably one of the better algorithms for pathfinding I've tried, but that doesn't mean it'll have everything written for you. Formational logic is pretty tricky itself, and it's very specific to each game, so that's something that you'd want to figure out and code yourself.

[undone coral]

what kind of game is it?

[drowsy falcon]

It is a city builder

Grid based

[drowsy falcon]

Yeah, it sounds about right

[drowsy falcon]

Ive implemented my version of A* to fit my game, but i need a clue to add some "randomness" that would make units spread out and take slightly different path every time

Adding a collider to each unit doesnt seem like a good idea, maybe add a random offset to the path they take?

[regal lava]

For RTS games, I've seen some designs by grouping units by local space and calculations relative to their distances, and using final path time calculations to add some distance between each unit. But having a bunch of units idling and taking their own path regardless of those nearby does seem quite a problem.

Colliders are an easy way out though, and you do see that in games a lot

Probably too taxing if you got a lot of units

[drowsy falcon]

Well i dont think i want my units to collide in my game

In my game walkable "road" cells are placed and units have to walk ON it

Just like city builder games where you place roads

So i want my units to spread out, but not too much so that they dont get out of the road

So collider not the best approach

Thinking about it, random offsets might work

[regal lava]

Yeah, seems tricky if you want it very fluid. It's just really depends how much is going to be active on your screen at once, so if you can just pool a bunch of units off screen you can maybe get away with adding temporary collider logic to those that are active.

[drowsy falcon]

Hey, i solved the buff system that i asked the other day, btw, thanks

[regal lava]

Oh nice gj ;p

[maiden turtle]

you can increase the cost of tiles close to units where the tiles have been selected as the path by said units. that way it would be less likely for the units to go by the same path. repeat the calculations at regular intervals

I've read this idea somewhere

[ripe kite]

Thanks

No, seriously. I need a normal Starcraft 2 style map file. Unity doesn't support that in any "normal" way. I'm left with two options: either write my own file format or trying to pull a squirrel on a fridge by making some Frankenstein monster out of unity supported entities.

[terse bobcat]

Hello everyone, im trying to spawn items random, but sometimes it gets spanwed inside a wall as you can see in the screenshot can someone tell me what im doing wrong?

{
    public GameObject item;

    void Start()
    {

        int i = 0;
        while (i < 4)
        {
            Vector3 randomSpawnPosition = new Vector3(Random.Range(-30, 30), 0.6f, Random.Range(-30, 30));
            bool isItemOnGround = Physics.Raycast(randomSpawnPosition, -Vector3.up, out RaycastHit hit);

            if (isItemOnGround)
            {

                int maxColliders = 10;
                Collider[] hitColliders = new Collider[maxColliders];
                int numColliders = Physics.OverlapSphereNonAlloc(randomSpawnPosition, 0.5f, hitColliders);
                for (int k = 0; k < numColliders; k++)
                {
                    bool isParentWall = hitColliders[k].transform.parent.name.Contains("Wall");
                    if(isParentWall)
                    {
                        Vector3 distance = item.transform.position - hitColliders[k].transform.position;
                        print("X: " + distance.x + " | Z:" + distance.z + " | " + hitColliders[k].name);
                        print(item.name + " has a distance from collider: " + distance);
                        print(" ");
                    }
                }

                item.name = "";
                item.name = "index: " + i;
                Instantiate(item, randomSpawnPosition, Quaternion.identity);
                ++i;
            }
            else
            {
                continue;
            }
        }
    }
}```

[upbeat path]

You generate randomSpawnPosition

Vector3 randomSpawnPosition = new Vector3(Random.Range(-30, 30), 0.6f, Random.Range(-30, 30));

You instantiate at randomSpawnPosition

Instantiate(item, randomSpawnPosition, Quaternion.identity);

But nowhere do you modify randomSpawnPosition if it is inside a wall

[terse bobcat]

yea i need help because i could find the right soulution yet

[terse bobcat]

do you have an idea?

[upbeat path]

well the obvious solution is to check if randomSpawnPosition is inside a wall and if it is move it

[terse bobcat]

yea i know as you can see in the code i did already, but the wall detection is not that good. So this is why i asked here if someone can help me

[upbeat path]

there is no code there that checks randomSpawnPosition

[terse bobcat]

i know did you looked at my code? Is there maybe a way to get gameobjects in a certain radius? This: int numColliders = Physics.OverlapSphereNonAlloc(randomSpawnPosition, 0.5f, hitColliders); does not work fine

[upbeat path]

you are doing

Vector3 distance = item.transform.position - hitColliders[k].transform.position;

I think that should be

Vector3 distance = randomSpawnPosition - hitColliders[k].transform.position;

[terse bobcat]

oh yea youre right 🙂

[upbeat path]

but even then it will not work correctly, you need to use the bounds of the wall

[terse bobcat]

but it wont effect the wall detection because Physics.OverlapSphereNonAlloc(randomSpawnPosition, 0.5f, hitColliders); does not work fine.

[terse bobcat]

Do you maybe know if there is a way to get gameobjects in a radius based on transform position

[regal lava]

Use overlapsphere

The one you're using only returns an int and not the ref to the colliders

[upbeat path]

OverlapSphere will do it as long as the gameobjects have colliders

but again, think about what you are doing, you are checking centre point to centre point, you should be checking if randomSpawnPosition is inside the bounds of the found colliders

[terse bobcat]

okay i got it thanks 🙂 @regal lava overlapsphere was the solution 🙂

[ruby viper]

Following up on my messages of yesterday, here is the full code leading to the weird behaviour. It doesn't fit in a single discord message so I hosted the code on github, here: https://gist.github.com/tbarusseau/709c25d7c8f35f73b5de9a3273eb0f5a
Pinging whoever might be interested in taking a look @undone coral @jolly token @gray pulsar @obsidian glade @long ivy @orchid marsh

[obsidian glade]

had a brief look - it seems like you're updating the value this.MaxLife may take when you call it (or rather, the branch in how it's calculated) which could cause problems in what is displayed in the debugger

[ruby viper]

Repeating again, this has nothing to do with the debugger, considering binding the value to a variable fixes the issue. Even ignoring whatever's displayed in the debugger, the behavior can be observed in game. Yes the debugger step is omega-weird, but the exact same thing happens in-game. I repeat: the weird behavior displayed in my debugger screenshots is also observed in-game.

And btw thanks for taking a look! Sorry if I sound rude, it's just that I've been repeating the same things over and over 😆

[obsidian glade]

what is this.SetLifeUnclamped(this.Life * modifier); doing?

[ruby viper]

Woops sorry, adding it to the gist right now

Updated. It just sets this.internalLife without any clamping or checks. This is to avoid possible infinite recursions.

So basically this is the part that updates this.internalLife in PostProcess, after modifying it. The value it's set at in this method is the value that's returned at the very first this.MaxLife property getter call.

I know it's a bit convoluted but it's the only way I found to have a clean and somewhat idiomatic way of handling stat calculations with an arbitrary number of modifiers

[obsidian glade]

so your this.MaxLife call is indeed modifying this.internalLife?

[ruby viper]

(also there is Linq in there but let's pretend it doesn't exist)

Uh, I guess it is

I see it now 🙈

Is it causing an issue because

                                                                             v updates internalLife during the Clamp
                   v old value                    v old value
            this.internalLife = Mathf.Clamp(this.internalLife + amount, 0, this.MaxLife);

?

[obsidian glade]

at this point I'm not entirely sure what you're trying to do - there's also a this.Life property being used

overall I think this code needs a cleanup of the properties so they aren't causing side effects like this to begin with

[ruby viper]

this.Life is just a public getter to this.internalLife

You're right, I need to clean this mess up

I think adding an explicit call to the update methods in private API would get rid of that kind of behaviours

[jolly token]

Then your problem is method argument evaluation order

If MaxLife evaluated first then this.internalLife + amount is after modification, if other way around then this.internalLife + amount is before modification.

And in C# it’s latter, they evaluated from left to right

[hardy nymph]

How do i convert a string to a component type ?

I have a string, consider this

string typeName = "Light";

I want to use this in GetComponent to get the "Light" component

of a game object

[sly grove]

GetComponent(typeName) works

[hardy nymph]

gameObject.GetComponent<> () // here I need to use the 'typeName' to refer to the light component

hm

oh

[sly grove]

but it's also... probably a bad way to do things

why are you doing it this way

[hardy nymph]

I get the type name in some json data, from a website.

[undone coral]

we discussed this

there is a package that lets you represent the scene in JSON

you should use that package

it makes it possible to round trip

its purpose is to enable USD support in Unity

which is really stupid but that's what someone somewhere wants

[hardy nymph]

Yea I'll look into it

[undone coral]

you are undertaking something that is

really hard for you

and you are using reflection when you do not need to

using reflection has made things much harder

you still haven't really explained why you are automating the unity editor through a website @hardy nymph

[hardy nymph]

Not sure if scene serialization will be relevant I want to send minimum amount of data from and to the web which is relevant , for speed. Here's an example:

Here I can edit the name, values of the components and it edits in the unity (in real time)

it sends only the relevant data, the serialized data of a component to unity

[undone coral]

you still haven't really explained why you are automating the unity editor through a website

there is already a text format for the scene files, the .unity file is a yaml format

you could easily edit the scene file, and ask the editor to reload the scene

and it would Just Work

those text fields correspond exactly to what you are making

why are you automating the unity editor through a website?

right now your approach is doomed

[hardy nymph]

I think the problem with reloading scene will be that it will reload the scripts.

Currently when the editor script is loaded it makes a socket connection. I guess I can have some kind of a check if it's possible.

[hardy nymph]

that was funny wording 🤣

maybe it is doomed, I'm not very experienced in this stuff but learning with time .

[hardy nymph]

it's just for some future projects, like later I might want to control the editor through a mobile phone (unity for mobile, something like that)

and for that I was thinking how can I show the scene in the phone, maybe by sending frames I guess

[frozen badger]

Anyone have any opinions on which Netcode setup is the easiest to work with?

I've got a slow-paced turn based game and I'm wondering what to use. I've seen UNet, Mirror, and the new "Netcode for GameObjects" but have yet to try any of them out

[sly grove]

honestly for a slow paced turn-based game I would even consider non-realtime solutions

You have the luxury to rely on TCP and could use e.g. websockets

[jolly token]

True, custom tcp server is a fit for turn based game

[frozen badger]

I could, but I don't want to be bogged down in the multiplayer code part if I can avoid it, but I guess that might be too much to ask for..

[undone coral]

yes but why?

[frozen badger]

Like, theoretically I could just replicate the entire game state to everyone right?

[undone coral]

for turn based games, you should probably use a pre-existing database-backed state

i believe there is something suitable in playfab, gamesparks

[frozen badger]

Ah, hm. That seems like a lot of back end for something smaller. It's a short single round game without persistency between rounds

[peak jacinth]

I might be thinking of something else, but I believe that GameSparks is about to be shutdown towards the end of this month.

[undone coral]

too bad

[rugged apex]

Is PhotonNetwork.IsConnectedAndReady a local check, or does it ping the server each time it's called?

[rugged apex]

Possibly Firebase? I built an REST API connection engine for it once.

[misty glade]

How could I serialize some objects that are external to Unity (in property drawers)? I'd like to get some inspector-run-time insight into the data without needing to debug.

public class MissionState // external POCO
{
  public string MyString;
}


public class MissionStateManager : MonoBehaviour // unity
{
  public MissionState MyMissionState; // <-- I want to see MyMissionState.MyString in the inspector.
}

Easiest I can think of is wrapping every property of the POCO in a public getter but that seems tedious..

[sly grove]

this is #💻┃code-beginner stuff but your class needs the [Serializable] attribute

[thick mulch]

Looking for someone who can help with a native plugin using android Visualizer API to fetch FFT data. I already have the data (created a Java plugin and get the data in Unity) but it seems to be not completely accurate. If someone knows a bit about this topic and can help polish the data, so that I get a nice looking frequency spectrum, I can offer 200$.

[misty glade]

Erm... I don't have control over the MissionState class is what I'm trying to say...

If I could slap Serializable on it I would 🙂

[sly grove]

Then you'd have to write a custom editor for your MonoBehaviour

[misty glade]

Hm... yeah. I suppose I could do something fancy and enumerate the fields with reflection and expose them that way, but that seems complicated..

[sly grove]

you wouldn't need reflection to write a custom editor

in any case you won't be able to save that data unless it's serializable

[misty glade]

Hm.. How do I cast/reference the object in a custom drawer? I'd like to make a custom drawer for an object of type PlayerWorkingMissions which is a custom type, but .. this doesn't seem to be legal:

    [CustomPropertyDrawer(typeof(PlayerWorkingMissions))]
    public class PlayerWorkingMissionsPropertyDrawer : PropertyDrawer
    {
        public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
        {
            if (property.objectReferenceValue is PlayerWorkingMissions pwm) //CS8121    An expression of type 'Object' cannot be handled by a pattern of type 'PlayerWorkingMissions'.
            {

            }
        }
    }

[sly grove]

so you're probably better off just making a parallel serializable object that you can convert to/ffrom the external one as needed

[misty glade]

like a serializable object that simply holds a reference to the non-serializable object?

[sly grove]

no

like a serialized object that holds the data you want to save

Unity assets and scenes can only save serialized data

if the data is not serialized, it will not be saved in the scene or the prefab or SO or whatever

[misty glade]

hm.. I don't mind that, I'm more interested in just seeing some information at runtime without having to stop and debug

I'm assuming reading the data is half of the bargain of [Serializable] though, right?

[surreal vessel]

so im using some method to instantiate an object, and in some cases i might want a component somewhere in the children of that object.

however i do this a lot so calling GetComponentInChildren() everytime will tank the performance

is there some way to only return it if its needed?

or maybe the compiler strips that so that it doesnt run when its not used? although i doubt that

i could make 2 methods, one that returns one that doesn but maybe theres a better way

[sly grove]

#archived-code-general I'd say, but almost every one of my prefabs just has a root script on it which directly references any relevant children

It's very rare any external script should actually need to directly reference any object deep within a prefab

[jolly token]

Having direct reference is the better way
Other than that it's just up to your logic

[sly grove]

All interaction with the prefab is generally done through said root script as well in my setups.

[surreal vessel]

im lokking for maybe a c# feature, maybe something like out parameters that are optional? im not sure

also the prefab is swapped during runtime

its all very dynamic so i cant just have references ready

[sly grove]

I'm not sure what you're saying follows from what you're describing

just because the prefabs are swapped out at runtime doesn't mean you can't have references ready

[jolly token]

There is method overloading or default argument... but this is starting to feel like #archived-code-general

[surreal vessel]

ok i guess ill go with Func() and FuncReturn() that returns what i need

Func() is just void

[sly grove]

I'm not really following. I thought we were talking about referencing components

seems like an XY problem now

[surreal vessel]

that was never my question

im asking whether there is a way to not return something if i dont need it

[sly grove]

in some cases i might want a component somewhere in the children of that object.
however i do this a lot so calling GetComponentInChildren() everytime will tank the performance
is there some way to only return it if its needed
Seems like you were asking how to get a component 🤔

[surreal vessel]

no

[sly grove]

Are you looking for the TryGet pattern?

[surreal vessel]

also no

this is talking about performance

[sly grove]

you've lost me then

[surreal vessel]

i have a method that returns something, however in that method it uses GetComponentInChildren() to get that thing to return

but

in most use cases of that method i dont actually need that return value

[sly grove]

you could return an object that lazily calls GetComponentInChildren if you access that particular property

[surreal vessel]

so its a bit pointless running something as expensive as that tens of times per second if i dont do anythign with it 99% of the time

hmm perhaps

[sly grove]

I'm still not convinced it ever makes sense to be calling GetComponentInChildren anyway vs direct references and good api design

[surreal vessel]

that seems a bit extra tho since it would just be a wrapper to that one thing

i instantiate a gameobject so there needs to be some way i get access to a component on it

[sly grove]

why

[jolly token]

Why just call GetComponentInChildren from caller

[sly grove]

or that

[surreal vessel]

to change some of the values which i sometimes might

[sly grove]

but why do you need a component deep in the prefab?

Have a script on the root of the prefab

which handles all of that

opaquely

[surreal vessel]

yea usually it is on the root but sometimes it might be a gameobject with children which each have that component

[sly grove]

My answer is still the same

even more so in that case actually

Common use case is instantiating rows in a UI

A CharacterDetailRow for example should handle setting all the individual Text and Image coimponents inside itself

the thing that instantiates it shouldn't do anything except pass a CharacterDescription to it

[surreal vessel]

yes the thing im instantiating does manage itself but rarely i might need to change some properties on it

[sly grove]

in that one tiny rare case, (which I don't think actually exists), just do what cathei said

otherwise, never call GetComponentInChildren

[jolly token]

If you really want something tricky... you could make hidden cache component to prefab root 😛

[surreal vessel]

i suppose i can return just the gameobject

not the component#

which should be no cost

makes a little less sense but it sort of solves this without 2 methods

[hollow stream]

Anyone have a good solution to having NavMeshAgents avoid each other?

Getting really weird interactions when applying a NavMeshObstacle to the Agents, I know they're not supposed to have both components but its the only solution I can think of right now... Disabling the NavMeshObstacle and enabling the NavMeshAgent in the same frame causes the unit to jump outside of the carved NavMesh from the Obstacle.

[sly grove]

disable carving?

[hollow stream]

Its a turned based combat game, so the idea is once its the unit's turn then it would disable the NavMeshObstacle and activate the NavMeshAgent, but it seems that this both happens within the same frame and doesn't give enough time for the NavMesh to "heal" the carving

Thus forcing it to jump outside of its own carving

[hollow stream]

Disabling the carving doesn't work either in this scenario btw

[sly grove]

can you just add a one frame delay between?

[hollow stream]

One frame doesn't seem to be enough

Any way to detect once a NavMesh has healed its carved out space from a NavMeshObstacle?

[odd veldt]

Hi, why the profiler shows there 2 PlayerLoops?

[undone coral]

editor scripts have Update too

it's just trying to express the difference between what you'd see in the player versus the editor

there is only one PlayerLoop the profiler is just expressing something specific in the timeline

[burnt palm]

I've got a 'Guid' does not contain a definition for 'TryWriteBytes' but can see it in the documentation?... not sure how to go about ...?? updating the core library?

My Guid reference show ..\2019.4.39f1\Editor\Data\MonoBleedingEdge\lib\mono\4.7.1-api\mscorlib.dll

Microsoft documentation shows it in .NET 5, 6, and 7 RC 1?? does 4.x in Unity and the 4.7.1 reference mean it's running .NET 7.1?

[thin mesa]

no, .NET 5+ is not yet supported. the 4.x means .NET 4

[burnt palm]

so this is 5.x.x ? I better try to find 4.7 than and confirm/deny it's existance.. I mean.. this is a Mirror script, they use 2021, but are supposed to support 2019 LTS.. I don't get why I'm missing this method though 🤔

[thin mesa]

https://learn.microsoft.com/en-us/dotnet/api/system.guid?view=netframework-4.7.1

ah I see the drop down now

and yes the method is not there 🤔

so.. I fixed an earlier problem by adding System.Memory.dll to my plugins... I wonder if I can import something like System.Runtime.InteropServices for an updated Guid struct? not used to fussing with stuff like this..

latest version on nuget didn't fix the error 😮‍💨

[undone coral]

?

what is your objective

[burnt palm]

There is a line in a Mirror script I was trying to update to that wants to use Guid.TryToWrite(), but 2019 doesn't have a TryToWrite method

[undone coral]

i would just replace it

I think I have 2021 installed, let me see if it's in there..

I don't know the severity/application of what the line/script is doing personally, could be important as is

only had 2020 installed, it doesn't have it either though

I think it's Sunday night for all of their crew, I'll wait on the problem till they're more online tomorrow (Monday noon already for me)

[jolly token]

Umm just make an extension method will save your headache

[burnt palm]

Is the full code visible somewhere to just copy paste? That's probably what they did, installing 2021 to look... it should work off the asset store as is though so, I kinda wanna talk to them anyway

TryWriteBytes supported from .netstandard 2.1, they are supported from 2021

[burnt palm]

alright, let me try this..

What's the most in-depth resource on Unity's UI there is? I can't find much except the "guide" on Unity's website which aren't very technical. Thanks in advance.

[regal olive]

Hello, I can't find any documentation on how unity rendering behaves in batchmode, anyone got any clue?

[flint sage]

It doesn't

[jolly token]

The ugui source itself is available
https://github.com/Unity-Technologies/uGUI

[random dust]

Why though

There's a lot of configuration in this so I doubt making it smaller is going to make it easier

A big file does not mean the code is bloated

Hi! I'm working on a little game jam game with some friends and we have this drawing system, but theres actually a problem! So one of the features we want to put into our game, is the ability to put away your drawing, rotate the player, and then put your drawing back. The player can't move, so the main problem is really rotation.
Our drawing system works by raycasting onto a "canvas" object and then at certain intervals of distance, adding the hit.point to the positions of a line renderer. Every new stroke is a new object, with a new line renderer (so that the ends of strokes dont connect) The problem with line renderers is that you can't rotate them when you're using world space. We tried using local space, but that ended up making the lines show up in a completely different spot.
My first attempt at solving this is making a list of all of the drawing objects, then making a list of arrays that contain their offset to the canvas. Then I take that list of arrays, and for each individual point, i apply the offset + the canvas position to every position in each list of linerenderer positions when i want to redisplay them. This works great (except the first point, for some reason, snaps to the position of the canvas with no offset?). However, when i try to apply rotations to the drawing, basically everything gets messed up. As you can see in the attached image, the drawing itself remains pretty much the same as it was when i put it down, but it ends up in a really weird position, it rotates really weirdly, and the first point still snaps to the canvas position. I've been throwing myself at this for like, 3 hours tonight, and this is my 2.5nd attempt this jam (attempts 1 and 1.5: i.imgur.com/JqO3Hgv.png). Can somebody help me out? Thanks :(

Hii ! Im looking for someone who could help me convert the java code into unity C#.

public void onClick() {
                Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:" + phoneNumber));

                startActivity(callIntent);
            }
        });

Help is much appreciated!

[shadow seal]

Not much to work off there

That could very well be C# code

Also "Unity C#" isn't a thing, it's just C#

[regal olive]

Yeah well this gives errors when compiling.
I have seen an example online of converting something similar : https://forum.unity.com/threads/redirect-to-app-settings.461140/ [second respond]
but i havnt managed to get it working

[shadow seal]

Well work through the errors

But again, we don't have much to go off here

[regal olive]

I think the problem is the fact that it is meant for java and not c#

[shadow seal]

Not at all

[tame tartan]

what is this code supposed to do?

[regal olive]

Call a phone number directly

without the dial screen

[shadow seal]

So you've provided almost nothing

There has to be more than that

[regal olive]

Im pretty sure it will work thanks to the Intent object

[tame tartan]

well there are no built-in features for calling phones in unity 😅 it seems like a lot of what this code does is based on an existing api that does a majority of the work for you

is this Intent object similar to a delegate?

[regal olive]

Imma be honest, I have no idea

I just know it works using java on Android

[shadow seal]

So it works in an entirely different set of circumstances

Have you thought about researching "Phone a number in C#" instead

[regal olive]

Yeah didn't find anything

[regal lava]

What does this have to do with Unity?

[regal olive]

I need it for my app

[shadow seal]

Very little

[tame tartan]

yeah a lot of these things are part of the android API :p

[shadow seal]

That's an idea, "Use Android API in Unity"

[regal olive]

Cool thank imma check it out

Thanks for the help, appreciate it

[regal olive]

what do you mean?

[austere marsh]

is it possible to grab the emission pass from the gpu buffer?

[undone coral]

in HDRP you can see if it's an AOV pass. the hdrp source code is pretty well written and you should be able to find where emission is by searching it

[undone coral]

you can try Application.OpenURL($"tel:{phoneNumber}")

https://docs.unity3d.com/ScriptReference/Application.OpenURL.html

[undone coral]

We tried using local space, but that ended up making the lines show up in a completely different spot.
did you try lineRenderer.transform.InverseTransformPoint to convert a world position to a local position in the line renderer?

you should use local space.

[tame tartan]

yeah! i actually saw a stack overflow article recommending a similar thing, and i tried it! it definitely changed the transform in a meaningful, but it wasnt success and i couldnt wrap my head around how to make it work, so after trying it i went back to trying ideas i was more familiar with

[undone coral]

what is your objective?

[undone coral]

hmm

you wrote a lot

are you asking, how do i rotate a line renderer?

that's what it sounds like you are asking

[tame tartan]

yes. i need to rotate a line renderer around the axis of the player

[undone coral]

the axis of the player
the player isn't an axis

[tame tartan]

player's up*

lol

[undone coral]

i think you need to use local space for the line renderer

if you wanted to add a point to a line renderer from world space, transform it to the local space of the line renderer

[tame tartan]

yeah, so that works. i can add points in local space and the points will appear where the player turns to, but they wont rotate to face the player

[undone coral]

wont rotate to face the player
do you mean the path's mesh is oriented the wrong direction?

that's a different problem

[tame tartan]

let me draw out an example

yeah

[undone coral]

so

there is a setting in line renderer

Alignment

did you try experimenting with this setting?

it should be set to View

[undone coral]

the points will appear where the player turns to
?

[undone coral]

okay

[tame tartan]

the lines will transform to the new position of the canvas. that part is solved. the main problem is that the lines wont rotate with the canvas

p much

[undone coral]

okay maybe let's start from the beginning

you are saying you want to be able to draw onto a rectangle naturalistically?

it should behave naturally?

as though we are in a 3d world drawing onto a page?

[tame tartan]

yes, as in, i should be able to draw onto a page, then turn my camera and the page, then have it turn along with the page

[undone coral]

because you wrote so much, it makes it sound like there's some non-naturalistic behavior you want to achieve

then have it turn along with the page
you keep saying this

[tame tartan]

like

[undone coral]

are you describing a bug, or some non-naturalistic behavior

[regal olive]

My objective is to send the frames generated by unity to another process. It works in non batch mode. I'd like to know more about what batch mode does.

[tame tartan]

i am saying that i want the lines to appear as if they stick on the page

like on a real piece of paper pretty much

[undone coral]

so a naturalistic drawing

[tame tartan]

ya

[undone coral]

there's nothing unnatural about the behavior

[tame tartan]

they do this if i dont rotate the camera

[undone coral]

you are describing

[tame tartan]

yaya

[undone coral]

okay

[tame tartan]

https://i.imgur.com/6NPaglp.png

they work if you dont rotate the camera

[undone coral]

well did you try setting the alignment to view?

otherwise, you can set it to Transform Z

and make sure the transform of the line renderer is pointing straight up

then it will just work

[tame tartan]

hmm okay, let me try that and report back to you

[undone coral]

what is the application?

[tame tartan]

oh its already set to view lol

[undone coral]

batchmode skips a player loop entry that renders all your cameras by default.

if you want to render a camera you can do something

[regal olive]

The application is playing the game in a browser page. I send the frames over a websocket and display them in a canvas.

[undone coral]

okay

that's what i thought

that is not going to work

[regal olive]

Why not?

[regal olive]

Thanks I didnt know about LateUpdate

[undone coral]

why does the application have to be batchmode?

i think this is going to be incomprehensibly hard for you

[regal olive]

Because no window has to be opened whatsover

[undone coral]

why exactly

what is your game?

or what is the goal?

the bigger goal

[regal olive]

The goal is that the user will ultimately only play in the browser (we have our reasons)

[undone coral]

the answer is complicated, but the brief reason is the performance is too poor

it isn't practical to try to develop this yourself

[regal olive]

in batchmode?

[undone coral]

in any mode

[regal olive]

it works fine without batchmode

[undone coral]

hmm

[regal olive]

its not 60 fps but its close

[undone coral]

hmm

well listen i make a unity streaming backend

i probably know more about this than anyone else

[regal olive]

we dont need 60 fps so

[undone coral]

no, it's not even going to work with 10fps

[regal olive]

it works at nearly 50

[undone coral]

it will barely work at all

hmm

i don't think you know what's going on yet is the thing

it's up to you

do you want to learn more or do you want to argue with me

[regal olive]

I want to learn more, I wanna know if batchmode will work

[undone coral]

well what is the big picture?

like what are you really trying to do? what is the game / the product?

[regal olive]

hmm it's online shopping, metashops

[undone coral]

okay

[undone coral]

here is a demo of how my technology works - https://player.appmana.com/watch/bonneville

i think you are very far from getting to that goal

which is okay

is it essential that you write all of this yourself?

[undone coral]

you should set it to transform z, and parent the line renderer to the canvas page

then set transform z to be pointing out of the page

then use local space for the line renderer

hope that helps

[tame tartan]

https://images-ext-1.discordapp.net/external/8AtwHXIki8w2W2KuxNIPgxDc2ZNS05w9JMiPwhjIS-k/https/i.imgur.com/WeZn7E9.png

so this is pretty much what happens with transform Z alignment(top) and view alignment(bottom)

p sure that these relate to the alignment of the material of each segment of line rather than the actual position of the line

[undone coral]

i think you are doing a lot of stuff sort of wrong

it is really hard to tell

i think your raycasts are funky too

and you have a lot of code going on

[regal olive]

yeah essentially, I just used unity render streaming for the input part, but I may drop it in the future

I'll watch your demo thank you

[undone coral]

how many years do you have to work on this?

[tame tartan]

i mean the drawings are offset to the canvas correctly, if they were to rotate in place to be flush with the paper, they would be fine

[undone coral]

i think you're conceiving of this as mashing up a lot of open source software, and i'm cautioning you that this is really hard

consider this: you weren't aware of LateUpdate

[slender stag]

Is there an asset to get feedback from the user and upload it as an issue to a private repository?

[undone coral]

crashalytics can do this i think

[slender stag]

Ima look it up, cause idk if my searching skills are getting worse by day, but can't find stuff these past few days

[undone coral]

i also googled "unity report bug from in game post to github"

and found a bunch of results

[regal olive]

a month I guess

I'll try LateUpdate

[undone coral]

okay well

are you a student?

[regal olive]

no, I'm a web developer, I just started a new job in game development

[undone coral]

why does it all have to be written by you?

[slender stag]

I looked for 'unity feedback create git issue' lol

[undone coral]

are you sure you can't use another service?

[undone coral]

lol

yeah i found like instabug and other stuff

i think back in the day i used crashalytics 🙂

[regal olive]

I don't know, we found nothing doing what we needed, and I thought it wasn't that hard to do myself, so I did it

[undone coral]

okay well it's really crazy hard

i understand you have some stuff in front of you that makes it look like it's easy

[regal olive]

it works though, it's just that damn batchmode that isn't working as I guessed it would

[undone coral]

it won't work period

[regal olive]

why not?

[undone coral]

well in order to get it to work, you're going to need a year or two of time

not one month

[regal olive]

but it works rn

[undone coral]

it really depends what you need to have working in a month

a demo for someone? a working website for many people?

[regal olive]

yeah a working website, in 2 weeks

[undone coral]

how do you plan to run your copies of a unity player?

[regal olive]

wym?

[undone coral]

well

do you guys have a budget?

like how much money can you spend running the thing that is rendering the items in the web shop

[regal olive]

yeah a bit

[undone coral]

how much is a bit?

[regal olive]

oh, I understand the confusion

the game runs on the user computer

[undone coral]

hmm...

what is the product?

like what are you making?

[regal olive]

well, sorry but I cannot give too many details, I already said too much probably

[undone coral]

yes, but i know so much about this

surely you see that it's high yield to help me understand

[regal olive]

my original question was about getting documentation on batchmode

[undone coral]

you're not going to be able to start the game correctly in batchmode

because you don't know enough about all this stuff

and there is no documentation

because nobody does this

except like me

[regal olive]

why?

[undone coral]

okay well i think you should ask for more time

you should probably ask for 6 months

if you made a promise for 2 weeks, i mean, maybe you are working for the kind of shop that just delivers something incomplete

i don't know

[regal olive]

that's not my question

[undone coral]

it's hard to say

[undone coral]

because you don't know enough about the internals of unity to make it work

what do you mean why?

[regal olive]

yeah but it seems you do

why do you think the game wouldn't run correctly on batchmode?

[undone coral]

okay

did you try what i said

[undone coral]

i don't think the thing i authored can help you but i think you'll figure it all out 🙂

[regal olive]

wym what thing

[undone coral]

i really think you should ask for more time
