In many ways TweenLite is the heart of the GreenSock animation library it stores all the core features necessary to create interactive animations and beyond using the plug-in architecture. In our first chapter our focus was on the core library features - TweenNano been able animation. We now cross over into TweenLite where the possibilities of intricate interactive animations begin. In this chapter we will learn how to react when the animation completes, we will create custom uses, use delays, kill animations and explore the various variables of the library.
