what are you using? if you are using dbc theres some functions i saw a while back to rotate sprite and if you using dbp i think i herd that it has a rotate sprite command and darkgdk i have no idea lol. and you can use MouseX() and MouseY() (for dbc and maybe dbp) to get the mouse position and then rotate it toward it.

Do you want a smooth rotation towards the mouse cursor? Or just a always 'point at' mouse cursor?

Well, first thing you need to do is find the angle from point A(object) to point B(mouse) Simple use of SIN() COS() will accomplish this. Then it's a matter of setting the object's angle. Either setting it, or adding a curvevalue().

I think the command ATANFULL is generally accepted as the best way to do this.
