I need help with a game I am making (not published yet) its a platformer and I want to know how to jump and also jump 'n run.
ever time I do I end up floating in air

So how are you moving in a y direction?

The best method for something like that is to have a y-velocity and in a loop you change y by y-velocity. If y-velocity is 0 you're not moving vertically, if it's positive you're moving up and if negative you're moving down. Then add gravity by changing y-velocity by a negative constant on each pass of the loop. That means when you're jumping you gradually slow down and then accelerate towards the ground.

Can you post a picture of that in a script? It would really help because I just sounds a bit confusing the way you say it.
