TweenMaxVars.startAt bug [SOLVED]

[bas]

hi i found a possible bug with TweenMaxVars (version 5.1) and the startAt method. The generated object in the vars property contains a repeatDelay property while utilizing the startAt method, not - as one would expect - an startAt property.

 

consider the following

 

vars = new TweenMaxVars().prop('z', 0).startAt(new TweenMaxVars().prop('z', -200)).vars;
trace(ObjectUtil.toString(vars));

(Object)#0
 repeatDelay = (com.greensock.data::TweenMaxVars)#1
   isGSVars = true
   vars = (Object)#2
     z = -200
 z = 0

 

change in data.TweenMaxVars

public function startAt(vars:TweenMaxVars):TweenMaxVars {
    return _set("repeatDelay", vars);
}

to

public function startAt(vars:TweenMaxVars):TweenMaxVars {
    return _set("startAt", vars.vars);
}

and the vars object is what is expected

trace(ObjectUtil.toString(vars));
(String) = (Object)#0
 startAt = (Object)#1
   z = -200
 z = 0

Great catch! Sorry about that - copy & paste strikes again.

 

It's fixed in the latest version.

cool - thanks - however

 

i still get an exception, it seems because vars is an instance of TweenMaxVars

 

ReferenceError: Error #1037: Cannot assign to a method overwrite on com.greensock.data.TweenMaxVars.

which originates from in TweenMax.as

override protected function init():void {
		if (this.vars.startAt) {
			this.vars.startAt.overwrite = 0;

 

my suggested patch was to extract the anonymous vars object from the TweenMaxVars instance before calling the _set method... That solves it, but perhaps it could be done differently...

 

suggested change (works for me):

public function startAt(vars:TweenMaxVars):TweenMaxVars {
return _set("startAt", vars);
}

to

public function startAt(vars:TweenMaxVars):TweenMaxVars {
return _set("startAt", vars.vars);
}

Exactly what I did in the latest version - sorry about that. It's available at http://www.greensock.com/tweenmax/ (and in your Club GreenSock account if you're a member).
