im trying to make a ball bounce off a wall but with no y axis involved. so it just stays on a certain height. but when i get the ball moving and it collides with the wall. it rolls downwards. ( i have yet to figure out how to make it go in the opposite direction yet) if it were to roll on the x or z axis due to its sphere shape, thats understandable, but why is it rolling downwards? is it also because of its shape? i am using rigidbody for this sphere and have disable gravity already. i am ASSUMING i can just stop this by checking if it is touching a wall and just make it stop moving but at the same time i just want to know why this is happening.
