You probably need to rework the way jump works in your game.
You should add an “is_on_floor” condition.
You may need place a hidden hitbox against the wall and add an condition to prevent the player from jumping when in collision with it, that’s if you’re not planning on doing a wall jump/grab.
great, glad I could help.
