Hi. I have some awesome game ideas and know how to use blender3D and blender3D GE acceptionally well. One problem I keep running into is how to make my characters jump. I generally only make them cubes and assign controls. Do I just need to model a character and assign IPOs to certain actions and buttons? Or do I need to do something to the physics? Please Help!!! 
I’m guessing your making your cubes Rigid Bodies. You can either make it just Dynamic instead, or lock all of the rotation axes in the Advanced settings (click the Advanced button in the gamebuttons).
If it’s still “tipping”, then you’ll have to post a blend file to show what you mean.
