you are going to have to clarify exactly what you have and what you need to do .

you have mentioned an object then you mentioned
a sprite , it's hard to understand what you want to
rotate if you say object and sprite , is it a 3d object
or is it a 2d sprite ?

being clear will help people help you.

if it's a problem in your code you are going to need
help with , please provide your code.
