How to create a realistic jump in bge I'm  trying to create a FPS game in blender game engine. When I do KeyBoard[Spacebar] sensor and hook it up to a simple motion of z +1 or something like that, the guys pops up really fast as if he didn't have any motion between being on the ground and being in the air. Is there a way to make a more realistic, more slow jump in BGE?
You can do this by using the Linear velocity setting under simple motion. This will make your character's jump motion look much more realistic. 

If you are using Character physics, you can simply use this setting.



You can change the settings for the character's jump speed and power in the Physics tab.



If you are using a dynamic object, or a rigid body object, you can use linear velocity along the z axis.
