Turning PMO gravity on and off

[sgn15]

I am using Platform Movement Object for my hero char.

I have a hero character that has an air attack that should move (can move vertical/horizontally, but not because of gravity) in air (meaning without gravity acting on the hero). While the air attack animation is playing, I set both the gravity and max y velocity to 0 and I want to turn them back to their default values and make the hero fall down (like default fall from jump) when the air attack animation is over. Basically the hero will have no gravity during this air attack only.

That or I want to simulate a jump (using Control X ) after the air attack animation finishes (so the hero is literally using the default jump of PMO). How do I use the simulate key functions of Control X?

My jump is the up arrow button.

I only need the action of the event. I already have the correct condition.

Please help. Thanks.

I tried Control X's "disable all keys" using an "Always" condition because I thought my original conditions were wrong but it still never worked.

Anybody can help?

P.S. the smiley in my original post was an X with closing parenthesis and I don't see an "Edit Post" button on it too (first post)
