i like the effect that ur crosshair gets bigger when u hold down ur mouse.
looks like a solid game so far, add sound, a menu some achievements / skills and ur first game is ready to go!
btw i think you cant move before you shoot for the first time. maybe add some text telling us to click so it can start.
heat seeking ? wouldn’t simple ai work ? the rocket class has to know where the x / y of the target are.
btw you can’t remove attachMovie part, that’s where the mc is added to stage
imho the error’s at the declaration of the class (or the RocketSeek function), if i were you i’d remove (or // it) everything below the attachMovie part, to see if the MC is even added correctly. then i’d add one by one
