Collisions With A Flipped Cube

I am creating a game where balls roll around inside a semi-clear box. You use the mouse to turn the box. But when I run the program, the balls just sit there (at 0,0,0)- until I turn the box. Then they fall and go right through the box.

I'm using this collision method:

Collisions SPHERE_TYPE,CUBE_TYPE,3,2

Also, I used the command: FlipMesh to make the box inside out.


Has anyone had collision problems with a flipped mesh?

Thanks

It's not the fact that you flipped the mesh - you probably need to set up an entitybox (for collision type 3), but ultimately it will be the fact that you're moving the object that is supposed to be collided against which screws you. The built-in collision system doesn't cope with that sort of thing.

Thanks for your answer. Okay... so is there any way of doing this? (Balls roll around inside a turning box.)

Can you rotate/turn the camera instead of the box, to make it look as though the box is turning? Then you can move the ball relative to the camera angles?

There's a dynamic collisionlib in the archives which may be able to handle this.

The only problem with that is I would have to change the way gravity is pulling on the balls inside. Good idea though!
