   I am toying with adding movement in my game that essentially follows an arc'd path. Can anyone point me in a direction for this or offer tips?

   I have made an arrow shooting game and needed some trigonometry refresher. This site has some good 2D game physics code/math. It isn't objective-C but is well written and easy to understand what they are doing to port it.

   I'm not sure exactly what you are trying to do, have player draw the path or follow a preset arc, or make a bullet arc/fall w/ gravity etc. I'm sure with some specifics someone here has done something similar already that could offer a pointer. For simple physics, just using the math sin/tan/atan/etc is usually pretty easy/fast, but if you want to do more physics based stuff, chipmunk or box2d physics engines included with cocos2d are pretty cool.

   Have you checked out the new bezier actions?
   There's an example in the SpritesTest demo.

   I am wanting to do the traditional bullet shot up, arc then fall across the screen. I didn't realize that we had bezier actions now. I haven't tinkered in 0.8 yet but I might have to give it a look and upgrade.
