<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">K –<div><div>The reason that skipTo() was picked over a more complicated interface is that only tweens which have start and end can be rewound or fast-forwarded – not the case for physics animations necessarily. But skipTo() can easily be used to rewind and ff:</div><div><br></div><div>Rewind:<span class="Apple-tab-span" style="white-space:pre"> </span>skipTo(0);</div><div>FF: <span class="Apple-tab-span" style="white-space:pre"> </span>skipTo(tween.duration);</div><div><br></div><div>Now, to the heart of your question which is skipTo + parallel or sequence.</div><div><br></div><div>Here is how I think we could implement that functionality:</div><div>1. PlayableBase should have a read-only duration getter that returns the max time of all children</div><div>2. SequenceBase might also need a duration getter that sums all step durations.</div><div>3. SequenceBase should get skipToTime() functionality. Alternatively skipTo could use time and the secondary method could be skipToIndex(). </div><div><br></div><div>The time-based one is easy to implement; you just run a sum of durations on each step and when the sum exceeds the time you back it up one and run skipTo() on the step with the remainder.</div><div><br></div><div>To implement a slider you could calculate a percentage against the Sequence's total duration.</div><div><br></div><div>Does this address your questions? I'm happy to help you add these features to the utils or, give it a shot and post your version!</div><div><br></div><div>- moses</div><div><br></div><div>PS: Go is naturally time-based. Do not use the useFrames option, there is nothing simpler or more intuitive about it. It is a specialty option that should be saved for special cases where you have to process things in frames. </div><div><br></div><div>PPS: Also be sure to take a look at the GoTestBase class included (there's also a GoFlexTestBase). It sets up buttons that let you perform all the play controls on a tween (see the included examples in the com.mosesSupposes.go.tests package). When you run the line super.addButtonUI(), the second param defines the skipTo() amount for that test, and will appear on the button.</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br><div><html>On Apr 21, 2008, at 5:12 AM, Karsten Goetz wrote:</html><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>Hi Coders,</div><div><br></div><div>I like the idea to seperate into different tweens. </div><div>I tried to do something like this a few weeks ago - but the work is not finished and has some bugs. </div><div>I've submited them anyway to SVN in my package ( KarstenGoetz ).
