I have a cool idea, I know its been done before, but its lots of fun.

basically my spaceship will face the mouse cursor at all times, so when I click the left mouse button it will shoot at the mouse cursor and if I click the right mouse button it will go forward.

the problem is I cant figure out how to make it face the mouse cursor. I have read the beginners guide book and it doesn't cover this.

of course we can rotate the sprite, but how do you rotate the sprite to face the mouse cursor? I know you would probably need to get the mousex() and the mousey() , but what do you do with those?

Any help would be appreciated.

thanks,
tone

look at the atanfull() command, it returns the angle between two points.
