I see. Im already awareness of this issue. Because of this, I'm trying to use a "boudingbox" around the player. Player have the PLATFORM behavior, while this "boundingbox" have the PHYSICS one.
Then, i "stick" both together, to make physics interations with world (like pull/push crates, even in a inclined surface).
If you check the little prototype at decodeweb.com.br/newgame you will see what is the problem. When I try to push the box, the box moves. But sometimes, it "passes" through it, specially when you pushes from right.
If I use only the physics in objects, the same problem occurs. The Capx file is in the first post.
Thanks for the help!
