Hello, and thank you for you reply
When i don't add mass; my object still jump after collision.
I don't want to increase the force needed for the jump.
I just want to add a little amount of mass, after each collision. The jump will decrease, until my object can't pass obstacles, driving to a game over.
But when my object enter in collision, it keeps adding mass, so my object drops and it can't jump anymore.
I attached a screenshot of my FSM, and after one collision, the "add mass" was active even when there were no collisions.
