Re-run. This is a very handy feature of Orx. You can see the debug borders on the bodies clearly marking where collisions can occur. | Re-run. This is a very handy feature of Orx. You can see the debug borders on the bodies clearly marking where collisions can occur. | ||

And notice that the ball has a spherical body and the borders have box bodies. Yet the ball is still falling through. Clearly something isn't right. | And notice that the ball has a spherical body and the borders have box bodies. Yet the ball is still falling through. Clearly something isn't right. | ||

That takes care of demonstrating physics and gravity, and also collisions between object body parts. If you would like to experiment a little further with physics, collisions and resulting FX, feel free to move on to the [[en:tutorials:physics|Physics Tutorial]]. | That takes care of demonstrating physics and gravity, and also collisions between object body parts.
