Change player movement

Hi, My player is ball and whenever i try to collide it with any 3d object model then the camera will change in different direction(that's ok just i need) but i want to change player movement on each direction not like fixed from start . Just make horizontal to vertical and then it will more easy to control ball , whenever camera change .
