This method is superior to the classic frame animation technique, everything being controlled from the programming code more precise than before.
Here are some key features of "TweenLite":
· onComplete, onStart, onUpdate callbacks (plus the ability to pass any number of variables to them)
· autoAlpha (toggles visibility of an object off when the alpha hits zero)
· Tween multiple properties with a single call
· Delay any tween by a set amount (good for sequencing)
· Tween the tint of any MovieClip/Sprite VERY easily
· Tween the volume of any MovieClip
· Unique "from()" call that allows you to use the current properties as the end values
· Use relative values
· Tween arrays of numeric values with a single call
· TweenLite automatically overwrites tweens of the same object by default in order to avoid conflicts (this behavior can easily be turned off too)
· Useful delayedCall() allows you to call any function after a set amount of time and even pass any number of arguments
· Has a big brother, "TweenFilterLite" that extends TweenLite and adds the ability to tween filters and advanced effects like saturation, hue, contrast, brightness, colorization, etc.
