[Golist] Resume on LinearGo that hasn't started ruins sync

[Stephen Downs]

There seems to be a flaw in the way that the setup call in LinearGo  
works when dealing with instances that haven't started yet and are  
responding to a resume call.

Here's an example scenario:

LinearGo instance with:
	delay: 2.5
	duration: 3.0

Steps to replicate:
1) Start the LinearGo.
2) Pause the LinearGo at 2 seconds.
3) Resume the LinearGo.

Expected results:
LinearGo would begin play at 0.5 seconds after step 3 (finishing the  
rest of it's delay phase, then starting the tween animation).

Actual results:
LinearGo begins play after another 2.5 seconds (as if it was reset).


Workaround:
Here's a kludge patch to the resume function you can implement in your  
LinearGo extended class:


		override public function resume() : Boolean {
			if (_state != PlayStates.PAUSED)
				return false;
			var mult:Number = Math.max(0, timeMultiplier) * (_useFrames ? 1 :  
1000);
			var currentTime:Number = (_useFrames ? _currentFrame : getTimer());
			var offsetTime:Number = currentTime - (_pauseTime - _startTime);
			if (!_started) {
				var offset:Number = (_useFrames ? Math.round(_delay * mult) :  
(_delay * mult));
				offsetTime -= offset;
			}
			setup(offsetTime);
			_pauseTime = NaN;
			_state = (_startTime > currentTime ? PlayStates.PLAYING_DELAY :  
PlayStates.PLAYING);
			dispatch(GoEvent.RESUME);
			return true;
		}


I imagine this flaw also kicks in when using skipTo as well.
