Hint: the launcher can actually do two things at once if you add together the command codes (1=up + 4=right gives 5= upright) or even fire and move at the same time.
Another neat trick is to tell it to fire for less than the full time- say 3.3 seconds. Now your launcher is armed. If you make it fire again, it'll do so without the long wind up.
Have fun, try wxLua for a gui. I'll upload the source shortly too. Email me at mediocuresurferATgmailDOTcom if you get any use out of it. Lua powered rockets
