I haven't worked all the geometry functions available yet ;) don't know the arcade engine
but here's a good source: http://www.2dcurves.com/conicsection/conicsectionc.html that's the place for curves ;) other wise wolfram's reference is absolutely great. but coming to thing of it, my pie control must do something like that... http://www.monsieurx.com/modules.php?name=News&file=article&sid=162 there's a setting button to offset the fields in and out of the center of the pie chart. That's the one you are looking for... the pseudo script would say r = radius of circle xy = center of circle or arc xyR[1..4] are the polygon's rects, for each item I in xyR if distance xy -> I > r you're out of the circle... cheers Xavier > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > Scott Rossi > Sent: Saturday, November 05, 2005 7:13 AM > To: How to use Revolution > Subject: Constrain Within Circle? > > Anyone have a formula to constrain object dragging within a > circular region? > > I'm guessing something like Arcade Engine has this in it, but > I really only need this one function. > > Thanks & Regards, > > Scott Rossi > Creative Director > Tactile Media, Multimedia & Design > ----- > E: [EMAIL PROTECTED] > W: http://www.tactilemedia.com > > _______________________________________________ > use-revolution mailing list > [email protected] > Please visit this url to subscribe, unsubscribe and manage > your subscription preferences: > http://lists.runrev.com/mailman/listinfo/use-revolution _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
