Please help with Physics and rotation

Games
#1

Hy all,

I have a simple game. Is a ball falling over some walls (like platform walls and floors), but the player can rotate the walls and the floors, (all this walls are inside a circle, and the player can rotate the circle).

The problem is that if I rotate the walls and the floors quickly, my ball cross the walls and the floors, like if there are not collision.

I set the walls and the floors as “static” and the ball as “dynamic”.

I please any kind of advise or suggestion.

I think you need to set the ball as a “bullet”. Then the collision detection is done more carefully (but at the expense of computation time). See the physics docs for bullet related APIs.

In addition, you might also find it helpful to set physics.setPositionIterations to a value higher than the default (which is 8).

Thanks,

Yes I try these but nothing. I also try all the possibilities to fix this that appears here:

Objects are going through walls: http://www.coronalabs.com/blog/2011/08/08/solutions-to-common-physics-challenges/

But nothing happens…

I´m reading that when the speed is big, is common to have bugs in Physics Objetcs.

Any other solution? [import]uid: 128859 topic_id: 30040 reply_id: 120302[/import]
