CommandCollection is a little ActionScript 3 library around using commands. It includes three tools:

• Process
• BranchProcess
• StateMachine

Process is a essentially a queue, in which you can put commands (synchronous or asynchronous), which will be executed sequentially.

BranchProcess is similar, but allows you to build a tree of commands with the ability of one commands result having an impact on which command comes next.

StateMachine is a classical finite state machine, that supports input commands for each state and is navigable. Means, you can aim for a state and the state machine will calculate a path to the target state and will try to reach it.

CommandCollection comes as .swc for integrating it into your project. You can also find the API documentation here or download it from the source repository under /trunk/docs.
