Knowing Mouse's Position?

Is there a way to change the mouse's position? I read the wiki and there is X,Y for the mouse but the cannot be set by a value... Is there another way?

No, for security reasons; tricking players into buying items.

Depending on what you're wanting to do with it, you could use "mouse.Hit", though I think you also have to take their screen size into account for it to work ideally.
