impostor cylindrical impostor should be collidable from inside

[jellix]

Hi,

a collision with a cylindrical imposter is only triggered when my "bullet" hits the outer surface of the impostor.

But my bullet should collide on the inside of the cylinder.

I've used "flipFaces()" with the mesh that the impostor is used on without an effect.

... is my question clear so far?

Hi Jelix

You can get that with a CannonJS meshImpostor, but might not be possible with a cylinderImpostor.

AND, only spheres collide with CannonJS meshImpostors.

Others may comment and have better ideas.

Notice the setPhysicsState on a setEnabled(false) cylinder?  Notice that when you enable 'cyl', you can't see it... thru the wireframe cyl2 (even though the wireframe cyl2 is scaled larger)?

It's all part of the magic... of BJS

Hi Wingnut,

thanks for that. In my case it seems like it might be the best to develp a special engine on my own.

You can use bouding box states for this as well to see if an object is contained.  Also I'm not sure but I think if you flip the.l normals of the object it should treat it like a container.  Don't quote me on that though.
