Poor mans jump mechanic

So I’m trying to make a jump mechanic in an isometric rpg. I just got this program and know very little.
But basically I’ve created a jump animation that works when you hit space.
How ever I’m trying to find away to turn off collision for the duration of the jump animation.
Any tips on how to do this?

Add a condition variable isJumping is = 0 to the event for collisions and in the event to change the animation to jumping make variable isJumping to 1 and make it 0 in the event that makes the character go back to the regular animation.

thanks, Imma try to decipher what ya mean and implement it.
