PhysicsShape.getBoundingBox() returns empty object

Bugs

Hi everyone,

Here is a playgroudn: https://playground.babylonjs.com/#Z8HTUN#904

The bounding box is an empty object. Tracing this from here to here there is just a type cast from “{}” to “BoundingBox”.

Couldnt find anything bounding boxy here: havok/packages/havok/HavokPhysics.d.ts at main · BabylonJS/havok · GitHub

Dirty quick fix: https://playground.babylonjs.com/#Z8HTUN#905

FYI, use case is to dispose/merge the mesh after creating PhysicsShape from it. The PhysicsBody just gets a TransformNode. Since the mesh is disposed, it would be useful to query the bounding box from the shape.

Best wishes
Joe

Indeed! Implementation is empty for shape bounding box. Is there some methods available with Havok we can expose? I didn’t find anything in the d.ts interface @eoin

Otherwise, it’s possible to do more or less like you did @Joe_Kerr and store the bbox in the physicsShape.

We do have functionality inside the WASM. We can certainly expose it; will get it into the next update.
