Arrow Firing

I want to make this a game eventually, but I’m not that far yet. Right now it just fires the arrows. I tried to make them fly realistically so the arrows follow parabolic flight paths. I’d appreciate any game ideas or any suggestions for how to make it better.

(and I know the arrow should rotate around the center, but now the registration point is at the tail, not a huge problem, but on some of the steeper angles it messes up the rotating a bit. I’m just too tired and lazy to fix it now.)

click and drag to set power and angle and release to fire. click path and it will trace the path of the arrows you fire.
