Add a getter/setter called reverse, then in your subclass override the setup() method to flip the settings when playing in reverse. Note that that method factors for LinearGoRepeater.easeOnCycle and other params.</div><div><br></div><div>I agree with Joel that you're very quickly going to want to add Start Value functionality; but you can also add caching functionality that snapshot current values.</div><div><br></div><div>All of this is suggestive of a more complicated tween API, so I would warn you that by desiring this one complex feature you are going to end up developing a robust system to support it. I do suggest you use subclasses where possible, and create a different Sequence class (like SequenceCA branches from SequenceBase).</div><div><br></div><div>BTW: What Fuse did was, it did not cache start values and could not rewind (due to all of these complexities!), but it was able to Fast Forward. During FF what it did was actually play each action with 0 duration, since remember in Fuse you could have wild card values etc., and it used the special caveat in ZigoEngine called skipLevel to indicate that callbacks and events should be skipped during those 0-second tweens. ZigoEngine was programmed to literally set the values for 0-second tweens, instead of running the tween. So, Fuse had all of that extra functionality that Go does not, but even Fuse shied away from Rewind which simply would have added a ton of code – not worth it for just one feature.</div><div><br></div><div>Good luck!</div><div>m</div><div><br><div><div>On Apr 21, 2008, at 1:34 PM, Karsten Goetz wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "> <div><br></div><div>ja, play reverse :-) There is this one line in LinearGo in update():</div><div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" face="'Courier New'"><br></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Courier New" size="3" style="font: 12.0px Courier New">_easeParams[0] = (currentTime - _startTime);</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" face="'Courier New'"><br></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" face="'Courier New'">I was hacking around a bit and you would cry if you could see what I've done to it... </font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" face="'Courier New'">Well, I think that reverse playing (not rewind? - my english, arghhhh) could be done with:</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" face="'Courier New'"><br></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" face="'Courier New'">play rewind</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font class="Apple-style-span" face="'Courier New'"><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Courier New" size="3" color="#00009b" style="font: 12.0px Courier New; color: #00009b">_easeParams</font><font face="Courier New" size="3" style="font: 12.0px Courier New">[0] = </font><font face="Courier New" size="3" color="#00009b" style="font: 12.0px Courier New; color: #00009b">_rewindTime</font><font face="Courier New" size="3" style="font: 12.0px Courier New"> - (currentTime - _startTime);</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">play forward</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><font face="Courier New" size="3" color="#00009b" style="font: normal normal normal 12px/normal 'Courier New'; color: rgb(0, 0, 155); ">_easeParams</font><font face="Courier New" size="3" style="font: normal normal normal 12px/normal 'Courier New'; ">[0] = </font><font face="Courier New" size="3" color="#00009b" style="font: normal normal normal 12px/normal 'Courier New'; color: rgb(0, 0, 155); ">_rewindTime</font><font face="Courier New" size="3" style="font: normal normal normal 12px/normal 'Courier New'; "> + (currentTime - _startTime);</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_rewindtime is the time set when changed the direction.
