You don't know which of a or b is going to be the player and which is going to be the platform. You need to check both, but you only check b. Also, which one is the fixture? self.fixture or self.physics.fixture? self.physics.fixture and now i corrected the check for b to also be self.physics.fixture

Thank you!
