   I want to reset a running animation to a particular frame. Even more so, when a user touches an animated sprite, I want to get the frame number at that touch, and based upon it reset the animation to some different frame number.

   So, for example if I have a 100 frame animation, and it's running, and the user taps it at frame 30, I want to jump the animation to frame 60; if he taps at frame 90 (say) I want to jump the animation to frame 20. And, of course I want the sprite to continue to animate. So: I need to be able to get the tapped frame, and to set the next frame in the animation sequence.

   Suggestions on 1) if this is even possible; 2) the calls or where to look, would be greatly appreciated. (I did look around here on the forum, and in the sprite.m code... where some internal methods look like _maybe..._...

   Wondering if anyone just happens to know....

   TIA

   Aha! It's in CocosNode! :-)

   H1! How did you manage to do that? I need to run an AtlasAnimation and leave the sprite showing the last frame of it.
   Thanks!

   Look at the very end of the CocosNode file. There are many animation related methods all covering what it looks like you need.

   Hi,

   I have a related question. I'm not looking to capture touches to skip around my animation, but instead have another event (like a Chipmunk collision) which cause frames to skip around or even be replaced. The general principle is that a character's animation moves in a loop. As the character gets hit, its appearance changes to reflect the loss in health. However, right now, I am stopping the animation and creating a new one. But the problem is that this results in a jump where the character was in the middle of an animation when it got hit, and now it jumps back to the beginning. I don't see anything in Cocosnode which will help me with this, but maybe I'm missing something...

   Thanks,
   Scott

   yeah, I'm missing what these helper methods for animation are in CocosNode... I see some stuff in IntervalAction, but nothing that lets you jump to a specific frame... that would be very helpful. Any thoughts?

   At the bottom of the CocosNode header (since v.0.7.1) there are the following protocols:

   @protocol CocosAnimation <NSObject>
   @protocol CocosNodeFrames <NSObject>

   I haven't used these, but the methods included here are probably what you are after.
