How do I regulate the jump?

Hello Guys,

I am creating a platform game, and I was wondering how can I regulate the jump?

I mean for example: In Mario depends of how long you pressed the button, how high Mario jumps.

So, I would like to know if exist some way to do this.

Regards,

What I do, is this:

half the y-velocity if:

jump is released, and

y-velocity < 0, and

player is jumping.

Something along these lines should work fairly well.

Hello sqiddster thanks for your reply.

But I didn't understand what events/actions use...

Could you please give me a more detailed explanation?

Thanks in advance!
