Can't change CharacterComponent's collider shape properties

Release Type: Official Release

Version: 4.1.0.1948

Platform(s): Windows

Describe the bug

Assigning a new ColliderShape into CharacterComponent in code (when game is running) and then calling CharacterComponent.ComposeShape(); causes the application to crash.

To Reproduce

1. Create basic character with CharacterComponent.
2. Assign capsule collider shape using Stride Studio.
3. Assign script which perform this code (ex. when key is pressed)

characterComponent.ColliderShapes[0] = new CapsuleColliderShapeDesc()
{
Length = 0.6f,
LocalOffset = new Vector3(0.0f, 0.70f, 0.0f),
Orientation = ShapeOrientation.UpY, Radius = 0.4f
};

characterPhysics.ComposeShape();

4. This will caus the application to crash.

Expected behavior
CharacterComponent starts to use new collider shape with new property values...

Additional context

• I need to change collider shape because of different character poses, like crouching and so on...

• It seems trying to use Dispose() on any type of collider shape causes it. ColliderShape.Dispose(); is called inside Stride.Engine.PhysicsComponent.ComposeShape() method.

• @Manio143 tip from discord:

I imagine we don't properly remove some reference after the dispose frees the native handle to the bullet collider and we still attempt to use it afterwards which is what causes the crash.

Start with CharacterComponent.ComposeShape() and Stride.Engine.PhysicsComponent.ComposeShape(), then trace how ColliderShape.Dispose() interacts with the native libbulletc handle. Reproduce the crash using the capsule-shape reassignment steps on Windows and verify that composing the new shape no longer crashes and applies the requested collider properties.
