[crude panther]

Hello, Im trying to make a new game but im stuck in the ball part, i dont have the knowledge to be able to make the player stay in top of a ball and being able to make it move and jump, my plan its to be able to move and jump and the player be able to walk normally in top of a ball. so if someone told me how to do it. it would be of great help. Thanks you :)

this is my first game so i just dont know how to this :(
