Right, I was thinking of making it an Input Number command - so when 5 is input, a conditional event (parallel process) checking for it makes the hero jump up then down.

But then there's the problem that input number means a little window pops up waiting for you the find the number 5 and press enter.

Instead, I've found a tutorial for jumping that may look complicated, but works pretty effectively, or so I'm told:

And here's a second one --> http://www.blade2k.net/writings/0/1/...c6a20152f68fa6

Hope it helps.
