Patches item #411879, was updated on 2001-03-28 04:45 You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=305757&aid=411879&group_id=5757 Category: None Group: None Status: Open Priority: 5 Submitted By: Christof Pohl (chripo) Assigned to: Nobody/Anonymous (nobody) Summary: Bug in PathAnimation.prototype.run() Initial Comment: The following "if" statement decides what to do at the end of an animation (loop, reset or simply stop): if (anim.frame>=anim.length/2+1) { if (anim.loops) { anim.frame = 0; } else if (anim.resets) { anim.frame = 0; if (this.dlyr!=null) this.dlyr.moveTo(anim[0],anim[1]); this.stopAnimation(); return; } else { anim.frame = 0; this.stopAnimation(); return; } } Unfortunately, the first "if" statement if (anim.frame>=anim.length/2+1) is wrong: it must be if (anim.frame>=anim.length/2) or there will be one more call of PathAnimation.run(), which will try to do the following: this.newX = anim[anim.frame*2]; this.newY = anim[anim.frame*2+1]; if (this.dlyr!=null) { this.dlyr.invokeEvent("pathrun"); this.dlyr.moveTo(this.newX,this.newY); } Let's say anim.length=10 (anim[0] ... anim[9] do exist) and anim.frame=5. Then (5>=10/2+1) => (5>=6) will return false. But anim[5*2] and anim[5*2+1] (as used in the moveTo() command) are undefined. Luckily, this will not produce an error in IE 5.5 (no other IE versions tested), but in NS4: DynAPI reported an error Error in file "[...]/api/dynlayer.js". Line Number: 187. Message: Can't convert this.x to an integer The value of "this.x" is "undefined" at the time this error message appears (as expected, because moveTo(undefined,undefined) was called by PathAnimation.run()). Please update "pathanim.js" (line 71 in CVS version from 28/03/2001).
