Hiya
I have this program detecting a collision and calling a function called changeDirection.
In here I need to check which way the character is currently moving and change it to the opposite.
I will attach RollableChar.as It will be missing few functions but these are not needed for this problem.
I have some code in this function but it wont work.
I would appreciate any help possible.
Thank you very much in advance.
