I can't figure out this jumping thing

The idea is: Pressing w (jump button) when not pressing a or d (left and right buttons) you jump straight up, (no problem here) And while pressing a or d the instance variable for jumping is set to 1 or 2 (left and right jumping direction)

So, if jump = 1 and D is pressed I want the player to jump forwards and if jump = 2 and a is pressed I want the player to jump backwards. This is what I can't get working. Any tips?

The platform behaviour by default allows you to jump forwards and backwards so what are you trying to do that's different?

Having it so you cant change direction while in the air. I managed to find a solution to it by adding a couple of variable checks.
