When working with Blenders physic simulation, I always wondered why it's so hard to setup some simple colliding objects. In order to do so, I have to perform the following steps (Blender 2.53):
- insert some animation data for the object which is going to collide with the rest
- switch to the logic Buttons, add some stuff starting this animation when the GE is launched
- switch render engine to "Blender Game"
- then it's possible to add rigid body physics to my objects
- check "Record Animation" in the Game menu
- start the Game engine and stop it after some time
- switch back to normal Blender Render....
Now I've got a critical mass of F-Curves, which is, according to the complexity of my scene, really hard to manage...
It would have been a lot easier, if I took Soft Body instead and made them really hard... :)
But why? Is there a reason for this procedure? In my opinion it's really strange that there are a lot of advanced features like Smoke, Fluid or Cloth, but no simple collision of two objects...
I know very little about the internals of Blender... It's probably a problem of the interaction of Bullet Physics and all the other, non-bullet-physics. But even if there are such problems, it's a really no-go in Blender 2.5's awesome straight workflow to follow the above described steps in order to get an animation of falling cubes... Newbies even might render this problem impossible... which is sad!
