Sorry I misread title
You could put an instance variable in player set to jump=0 and have it set to 1 when jumping. In your collision event with wall have it condition out jump=0.
You might find it easier to turn off wall collision and use is-overlapping instead then if its overlapping wall and jump=1 it ignores overlap and passes through otherwise have it stop movement and maybe move back a pixel or two. The key is you need to set the jumped items collision/overlap and not the players.
