Rotating MC

hey there :puzzle:,

i have a circlular MC and 3 buttons…im not to great with rotation and stuff, i was just wondering what do i have to do to make the circle rotate once and gradually slow down when the buttons are click…it would be the same code for any button i dont want any swanky effects just to rotate on the centre axis once then gradually slow down…

so yah what kinda thing would i have to use to make this effect…

thanks :pleased:
