void actor_to_screen(int *x, int *y)

Is this the correct syntax for the script editor?
actor_to_screen(&xmouse, &ymouse) //convert mouse coordinates to screen coordinates.
What use would this have in a game or program?
TIA
actor_to_screen(&xmouse, &ymouse) //convert mouse coordinates to screen coordinates.
What use would this have in a game or program?
