Short hop: You will need a a few moves for this. A jump startup move that chains into a short hop move, A short hop move with it's input set to on release.

Double jump: You can use basic moves for this, but the double jump keeps it's current X force, meaning if you do a forward jump and try to double jump back it won't change X forces.
You could try a move file for the double jump instead.

I mistyped regarding the basic move double jump, I meant to say if you do a forward jump you can't do a double jump back as the jump will keep it's current X force.
I'll see if we can get that behavior changed code wise sometime.

Startup is your call really, 4 is a nice solid quick amount.

My jump looks way to high to be a short hop does it have to do the animation?
