for the left/right/wait the instruction preforms for the amount of seconds entered by the player... and then the next instruction starts, for the jump it was tricky because I can't know the time the jump will take... so I must check if the player was on ground again... but that didn't work at the time and I didn't know why so I decided to make all jumps last for 2 seconds... and after reading your comment I tried to fix it... the problem was that I checked if the Player was on ground right after the instruction starts executing... that means right when the player starts to jump and is still on ground...
