>>2343935>In Adobe document, which element I should read more to do this?Hmmm, maybe read up a bit about onClipEvent(enterFrame) and onEnterFrame.
http://www.sitepoint.com/forums/showthread.php?484448-onClipEvent(enterFrame)-vs-onEnterFrameControlling the actual playback and reversal uses a variable; something like gotoAndStop(playbackvariable) where playbackvariable controlled by a formula. The formula is the same as in physics; the velocity=distance(difference between previous position versus current position) / time (difference between the span of the currentframe and a previous frame). If you don't care about controlling the slow or quick the velocity is, I think you can get away with just nextFrame(); or prevFrame();
>What keywords you might suggest for me to google? In a sense that it relates the topic in programming way in depth (if any), not general.Generally, just type in "actionscript 2 or 3" + "general description of your query"
>Anyway, just curious, what are you up to after AC?Javascript and C#. If you can understand AC2 or 3, it will be familiar to you.
>>2344368I wouldn't mind helping people out on the programming part if they are truly interested. I can't keep making flash games forever and it would be awesome if people would start making games for me :p. I'm self thought so the resources are available to you online.
