Problem In GE

I have created a tower with many cubes. When I start the game, every cube just jumps up in the air. Can someone tell me how I can fix that problem.

Just guessing that all the cubes are rigid body or dynamic; you should try just stacking one or two, to make sure the tower holds before trying to make a building out of them. Try making sure that the collision margin is set to 0 (I think that’s correct), or giving the cubes a collision mesh that is simple and exact (i.e., each cube’s faces don’t overrun into the faces of the cubes next to them).

Ok, thanks shall try :smiley:

Also check the bounds are set to cube…

Enable Physics Visualization in the render options. That may help you.
