My world objects are triangle meshes and the player are made out of primitive boxes as the collision skin. <br />The only way I can see of doing this is to add and remove the collision skins in the physics system depending on what I want,[url=http://www.floware.fr]michael kors paris[/url], but I am afraid I will get some performance issue. Also, I don't want the passable object to turn back on its collision detection when a player is still inside the object. If I remove the collision skins from the physics system, then there's no way for me to test whether the player is inside a disabled collision skin. <br />Any suggestions as to how I may be able to approach this problem? <br />Walking through the engine code a bit, I thought I had find the solution but it's not working as I thought it should. <br />What I've found out is the CollisionSystem class has this DetectAllCollisions method that does the collision detection calculation (as far as I could tell). It takes in a list of bodies that are currently active as a parameter and I'm assuming those are the bodies that get detected for collisions. There is a SetActive and SetInactive method for the body objects and I thought if I set the bodies to inactive, the collision detection won't be performed. But I was wrong and even though the bodies are inactive, collision detection is still being calculated.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/subSilver/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
