Is it possible to load "Flax" in my C# WinForms/WPF application and and use Flax as a control in part of a form?

You can see and select items that are not a valid type on the list with following error.

Steps:

• Create new Script.
• Edit Script. Change its type from Script to for example Actor
• Reload Scripts (or wait for auto reload)
• Select our new script from AddScript button
• Exception

Input.InputText is a null terminated string.

Test code:

        private void Update()
        {
            string text = Input.InputText;
            if (!string.IsNullOrWhiteSpace(text))

I've been trying to make something akin to constructors for generic scripts.

Steps to reproduce:

Add the following script

public class GenericScript<T> : Script
{
    public static GenericScript<T> Make()
    {
        var script = New<GenericScript<T>>();
        script.Enabled = false;

        return script;
    }

    public static GenericScript<U> Make<U>()
    {
        var script = New<GenericScript<U>>();
        script.Enabled = false;

        return script;
    }
}

Attempt to create an instance of it in some other script's Start()

// Simply crashes
var otherTest = GenericScript<Vector3>.Make();
Actor.AddScript(otherTest);

// Also just crashes
var otherTest = GenericScript<Vector3>.Make<Vector3>();
Actor.AddScript(otherTest);

It should result in Flax crashing.

When importing music into a folder and then opening the folder, the FlaxEngine crashes.

Steps to reproduce:

1. Find some music, I used a random .mp3 file
2. Open the Content folder
3. Drag and drop the music into the SceneData sub-folder
   
   
4. Import it and wait until it's done
5. You currently can't see the imported music, because it's in a sub-folder
6. Open the sub-folder. Crash.

Interestingly this doesn't always happen. If it didn't crash, just delete the imported music and try again.

Hey it's me again, I've found few typos when digging through generated API

• BoxBrush's UsePerspective property should be named ScaleInLightmap (based on internal calls + summary)
• DirectionalLight's ShadowsMode and MinimumRoughness properties have switched Internal calls corresponding with them
• PhysicalActor doesn't have .Gen.cs counterpart (I'm not sure if it's a bug or not)
• PointLight's ScaledRadius calls Get/SetSourceLength instead of Get/SetScaledRadius... MinimumRoughness and Color property are missing summaries (they are blank)

OnCollisionExit is called when Rigidbody stops overlapping another collider. OnCollisionEnter is not called again even if Exit was previously called and rigidbody is in sitting on a collider (due to gravity).
OnCollisionStay is called in that state.

Expected logic:
OnCollisionEnter - Is called once when collider begins collision with another collider
OnCollisionStay - Is called each fixed update when collider touches with another collider (One fixed update after Enter)
OnCollisionExit - Is called when collider ends collision with another collider

OnCollisionExit is not called sometimes

Snipset - Attach to rigidbody with collider

using FlaxEngine;

namespace MyProject
{
	public class Script0 : Script
	{

	    private void OnCollisionEnter(Collision c)
	    {

There is no really reproduction steps, but general steps what has happened with no real reproduction yet.

• Lunch Flax with the prepared project that has a script attached to an Object Update() {Debug.Log("T");}
• Make modifications to the script, play the game, and repeat this point multiple times. (First modification should remove Debug.Log("T") for better effect)
• See after a few tries multiple things happen:

New Script with default values is attached
2.
T is logged again
3. Another reload has 50-50 chances of a crash or things will go back to normal (your current script)

Hey,

I've probably found a "bug", the property MousePosition in GUI/Window.cs (line 98) is marked as bool instead of Vector2... this is also in Window.Gen.cs (line 98, 621 and 623).

I originally wanted to pull my edits but, because the edits would be in generated part of API i rejected that idea.

Issue description:

If an object have list that is serializable and can be displayed in the Properties window, and this window is visible (list can be retracted) high CPU spikes are produced under GUI.OnUpdate self. The more elements the higher impact.

The expected result would be to NOT serialize lists displayed in Properties unless they are expanded.

Steps to reproduce:
Create empty actor, attach this script. Select this actor on scene

    public class Foo : Script
    {
        public List<string> List = new List<string>();
        private void Update()
        {
            List.Add("RANDOM ITEM CONTENT");
        }
    }

NOTE: Impact is higher if object in list is more complex. For this example i have 20ms per frame of serialization time (even with 1 item in it)

Flax version:

0.3.6176

public class TestScript : Script
{
    private void Update()
    {
        Assert.AreEqual(0, Input.MousePosition.X); //Currently is 3.402823E+38
        Assert.AreEqual(0, Input.MousePosition.Y); //Currently is 3.402823E+38
    }
}

Attach to Flax returns this error amount of files you have in the project.

Debugging is imposible for filles (all files?) that has thrown this error. I have only one instance of VS open.

I attempted to automatically reimport files when their source file changes. However, sometimes, I was faced with the following error:

Assertion failed!
File: Engine\Content\Storage\FlaxStorage.cpp
Line: 1057

Expression: _chunksLock == 0

Steps to reproduce:

It's a bit hard to reproduce; usually it takes quite a number of edits in various files until the error occurs.

Also, after the error happens, this happens when I try to clean up the temporary files I created:

The following code seems to cause it.

BinaryAssetItem item = Editor.ContentDatabase.Find(SOMEPATH) as BinaryAssetItem;
if (FlaxEngine.Content.Load(item.ID) is BinaryAsset test)
{
    test.WaitForLoaded();
    test.Reimport();

The Flax Launcher doesn't escape user input. For example document.getElementById('projects-content').innerHTML = generatedHtml; where generatedHTML includes the project name.

Steps to reproduce:

1. Create a new project
2. Edit the Project.xml to include the following

<Project>
	<Name>ZZXXMyProject'&lt;br&gt;hi&lt;br&gt;&lt;img width=150 src=&quot;https://images.pexels.com/photos/20787/pexels-photo.jpg?auto=compress&amp;cs=tinysrgb&amp;dpr=1&amp;w=500&quot;&gt;</Name>

4. Open the Flax launcher and stare at the cute cat picture.

There are various tools to save you the trouble of manually encoding HTML.

Additional information:
This can be abused by getting someone else to download your project. For example, by uploading your project to GitHub and advertising it on Reddit.

Then, the attacker could trivially inject JavaScript into the Launcher and do potentially undesired things.

The easiest way to pull this attack off is by editing the <Name>ProjectName</Name>

3. Open the FlaxAPI.sln file using Visual Studio and edit the FlaxEngine Project Properties as follows:
   
4. Click on Attach to Flax. This starts Flax or attaches to the current Flax instance.

When changing the type of a serialized variable to a different one, it might be nice if Flax attempted to convert them.

e.g. I changed a float to an int

Exception has been thrown during ManagedSerialization::Deserialize.
Input string '30.9876175' is not a valid integer. Path 'Count', line 1, position 136.

I'm not entirely sure if this is an issue or works as intended ™️ .

Anyways, I was using the FlaxEngine JSON serialisation and attempted to serialize a private field from the base class. To my surprise, this didn't work.

(After a bit of digging, it seems that this GetFields call right here doesn't return private fields from the base class)

Steps to reproduce:

[Serializable]
public class BaseClass
{
    [Serialize]
    private string _wellHidden = "you won't find me";
}

[Serializable]
public class DerivedClass : BaseClass
{
    [Serialize]
    private string _derivedHidden = "you might find me, I'm in the derived class";

    public string VeryPublic = "easy to find";

    [NoSerialize]
    public string NotSerialized = "not serialized";
}

and

Debug.LogError(FlaxEngine.Json.JsonSerializer.Serialize(new BaseClass()));
/* Outputs
{
	"_wellHidden": "you won't find me"
}
*/


Debug.LogError(FlaxEngine.Json.JsonSerializer.Serialize(new DerivedClass()));
/* Outputs, note how _wellHidden does not show up here:
{
	"_derivedHidden": "you might find me, I'm in the derived class",
	"VeryPublic": "easy to find"
}
*/

Hi,
Excellent work on your engine, I'm also working on .NET game engine with Vulkan, DirectX12 and Metal, probably will emulate some next gen rendering features (like CommandBuffer) on OpenGL for mobile, the engine is here https://github.com/amerkoleci/Alimer and I will start to commit code from my private repository there.

Any plan to have some beta/WIP release?
I saw you've done lot of job but at the moment is not possible to test anything.

Thanks,
Amer

It'd be nice if UI controls had a green outline when selecting them. Especially panels, since they are invisible by default.

Steps to reproduce:

Add a new panel. You can't see it.

To visualize what it looks like, you have to manually change the background color.

I wrote a little script to spawn a bunch of (temporary) prefab actors. It spawns them OnEnable and destroys them OnDisable. So far, everything worked beautifully.

However, after adding [ExecuteInEditMode] to it, things broke down. It spawned actors without removing them. This might be a bug?

Also, a quick fix is using [Serialize].

[ExecuteInEditMode]
public class TenSpawner : Script
{
	public Prefab PrefabToSpawn { get; set; }
	public int Count = 10;
	
        // Quick fix
	// [Serialize]
	private Actor _container;

	private void OnEnable()
	{
		// Safety check
		if (PrefabToSpawn == null) return;
		
		// Create a new container/reuse the existing one
		if (_container == null)
		{
			_container = New<EmptyActor>();
			this.Actor.AddChild(_container, false);
		}
		else
		{
			_container.DestroyChildren();
		}

		// Add a bunch of children to it
		for (int i = 0; i < Count; i++)
		{
			var spawnedActor = PrefabManager.SpawnPrefab(PrefabToSpawn, _container);
		}
	}

	private void OnDisable()
	{
		// Clean up after yourself
		Destroy(_container);
	}
}

Problem: Path doesn't update when you change project name.
Expected behaviour: Update project path when you change project name.

ScreenToClient returns the wrong result when a control is scaled.

I created 2 UIControls (buttons) and scaled one of them. If the scale is 1,1, everything is fine, otherwise, the results are messed up.

public class Screen2ClientBug : Script
    {
        public UIControl ScaledControl;
        private Button _buttWithScale;

        public UIControl ScreenMousePosGrabber;
        private Button _screenMousePosButt;

        private void Start()
        {
            _buttWithScale = ScaledControl.Get<Button>();
            _screenMousePosButt = ScreenMousePosGrabber.Get<Button>();
        }

        private void Update()
        {
           //Both control's positions are (0,0), so this works perfectly fine
            var n = _screenMousePosButt.ClientToScreen(Input.MousePosition);

            _buttWithScale.Text = _buttWithScale.ScreenToClient(n).ToString();
        }
    }

I just tried out WebSockets again, it looks like there is an issue with a missing DLL?

Steps to reproduce:

// All certificates are now valid
ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;

// WebSocket
var x = new ClientWebSocket();
x.ConnectAsync(new Uri("wss://echo.websocket.org"), new System.Threading.CancellationTokenSource().Token);

2. Use the Game Cooker to build the project.
3. Start the built .exe
4. Check out the logs %localappdata%/<Company Name>/<Project Name>/Logs

Running the project in the editor and checking out the Logs folder also works.

I tried to create a script that destroys itself after completing it's task

Steps to reproduce:

Apparently this causes a silent crash. If you add the Enabled = false line, it seems to work.

public class Script0 : Script 
{
private void Start()
{
	//Enabled = false; // Can apparently prevent the crash
	Destroy(this);
}
private void Update()
{
	// Without "Update" Flax doesn't crash either
}
// It might also be possible to cause this by adding OnDisable() and whatnot
}

{
  public RigidBody Ship; // Make sure that this rigidbody doesn't have a collider

When throwing an exception its cached internally even if manually try-catched

try
{
	throw new Exception("E");
}
catch (Exception e)
{
	Debug.LogException(e);
}

Expected result:
The exception is only displayed once on LogException debug log.

I'm not sure if this is a bug with Flax or if I just messed up something.

Anyways, I just modified https://github.com/stefnotch/keyboard-letters-game to "properly" handle multiple keys being pressed at the same time. However, the TextRender doesn't seem to always cooperate. It quite frequently messes up and only shows one or 2 keys instead of all of them.
e.g. Something like FxEg instead of FlaxEngine. Or, w instead of aw.

To reproduce:

1. Download the latest code ( https://github.com/stefnotch/keyboard-letters-game )
2. Open it with Flax
3. Play around with it
4. Make sure your keyboard can actually handle multiple keys being pressed at the same time (keyboard rollover)
5. Spam a lot of keys at the same time
6. Bug should occur.

Screenshot:

As you can see, the code is setting "WADS" as the string, however only "WAD" gets displayed.

In the main editor window, where you can look at the scene and edit it, there seems to be a small, invisible something. The approximate location of it has been marked in the image:

When you right click there, instead of being able to drag the scene, nothing happens.
