.NET Headers 2.0

[Rekindled Phoenix]

Thank you for all your hard work!

Hi and great work. It's good to see solid support for C# and continuity in development ... although I'm struggling with event callbacks, to be precise with the collision callback!

 

I don't get it working. I always receive a FatalExecutionEngineError which reads as follows:

 

The runtime has encountered a fatal error. The address of the error was at 0x662cee12, on thread 0x1950. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

 

Some code to it:

var groundBody = new Body.Box(10, 0.1f, 5) {CollisionType = 1};
var ground = new Mesh.Cube { Color = Leadwerks.Color.SandyBrown, Scale = { X = 5, Y = 0.2f, Z = 2 }, Parent = groundBody };

groundBody.Position = new Vector3( 0, -0.5f, -1 );

var sphereBody = new Body.Sphere(0.045f) {  Mass = 1, CollisionType = 1, Elasticity = 2f};
var sphere = new Mesh.Sphere { Scale = new Vector3(0.05f, 0.05f, 0.05f), Parent = sphereBody, Position = sphereBody.Position};

sphereBody.Position = new Vector3(0, -0.65f, 0);

sphereBody.Callback(sphereCollisionCallback, (int)EntityCallbackType.Collision);

 

The main loop:

while (!Window.HasRequestedClose)
{
     if ( Leadwerks.Keyboard.KeyHit(Key.U)) {
           sphereBody.Velocity = sphereBody.CalculateVelocity(new Vector3(0, 1, 0), 3.125f);
     }

    Timing.Update();
    Framework.Update();
    Framework.Render();

    Leadwerks.Graphics.Flip();
}

 

And the callback itself:

 

        public void sphereCollisionCallback(IntPtr entity1, IntPtr entity2, Vector3 _position, Vector3 _normal, Vector3 _force, float speed) {
           Core.HideEntity(entity2);
       }

 

Is this a bug in the implementation of the headers when handling callbacks / delegates internally?

Did I make some mistake somewhere?

 

I am using Visual Studio 2010 Prof, Windows 7 x64 and the latest C# Headers 2.0 from Aug. 26th.

 

Glad for any help I can get ...

 

Best regards

Are you utilizing our custom engine DLL, or the one provided with the SDK?

[alphabit]

The one provided with the headers. But also tried in my desperation with the 2.40, 2.32 and 2.31 ( knowing that it shouldn't work anyway).

[CopperCircle]

The new headers are great, thanks. Look forward to the rest of the tutorials also. Keep up the good work.

FatalExecutionEngineError

 

I have attached a small test class that should reproduce the behaviour. Simply call it quick and dirty using:

 

new TestCollisionCallback().RunTest();

 

 

Edit:

And press the "U" Key once or a couple of times, so that you see a sphere jumping up and falling down (I admit, it's way too fast).

As soon as collision is detected, the error occurs.

 

Best regards
