Jumping

Argh... I'm having some problems. When I try to make a common event that allows you to jump by pressing a button, the whole jumping thing is messed up. Here's a rough thing of what it looks like (If replaces the conditional branches ):

If Key (Whatever) is pressed, then:
  If Sprite faces left:
    Move event: Jump (-2,0)

And so on. Oddly enough, on one press, the guy jumps then jumps back, jumps then jumps again, or regularly jump. Is this just a problem with my RPG Maker?

No, but you will need to put a wait event. The program runs so fast that it might be going through the event twice before you lift your finger from the key.

Yep, that's it, set it maybe to around 10 and that should fix it.
