I'm trying to program my first game without templates, a third person shooter. The gameplay and graphics will be similar to American Mcgee's Alice. But the plot will be differnt and all that. It will follow the same principle though: The world's gone up-side down, the hero has to set it right.

At the moment, I'm trying to make a script that jumps when I press space; but I don't know how to do that. >.<
