Move & Jump Functionality in 2D Platformer

Question

I'm trying to make my 2d character move and jump when a or d pressed the same time as space pressed. I think I have tried anything but I can't find the solution. What I did wrong?

Answer 1

Your if branches are exclusive. Ie. code is checking if you are pressing right, walk right. If not, check if jump is pressed. This is easily fixed by changing elif to if:

if Input.isactionjustpressed("jump"):
    state = JUMP

You might want to do something similiar with crouching etc.. Think what cases should be possible together, which not. Or move higher priority ones higher in the if cases (check jump first, then walk).

it didn't worked
