As I needed that for our game earlier today, I did some research and found out that is not natively supported yet.
It looks like that was once supported in sprite.add by entering a negative number to frame count. But that is not the case anymore.
I found some other posts requesting an update to spriteInstance.timeScale allowing it to support 0 (for pause) and negative numbers for reverse playback. That kind of implementation would be very very useful.
Another option would be using a new [loopParam] setting for sprite.add . For example -3 might play it backwards once and -4 play it backwards in loop, similar to current bounce playback settings.
Or object:reverse() (currently for movieclips only) might be extended to support sprites…
Right now I solved my problem by using sprite.newSpriteMultiSet() but native support would be much easier than applying that ‘hack’ to my already working code…
Thanks for looking…
