Hi~
I have a few questions using ogrenew in my map editor program. First, I implemented mouse dragging so that the position and direction of the object can be adjusted after creation. Then the problem came. If I place the object without dragging, the tree collision works. If I rotated it or moved it, my car could drive right through it. I wonder whether I have to use "body" all the time in order to do some move and rotation? Currently I'm using only the object node. Another problem is that SSCube.mesh is a very weird geometry created at runtime, will it work with TreeCollision if I just pass its scene node to TreeCollision?
Appreciate any help...
Solution:
I see no point to setup physics during editing mode, so I keep track of all scene nodes and setup physics when switching to play mode all in once.
