Simple Option Stacker is the only Stack-based Finite State Machine available on the Unity Asset Store, to date. The SFSM system is a HUGE improvement on the normal FSM, and greatly simplyfies the process of writing an AI.

Under constant development - Want a feature implemented? No reason to spend extra development time! Send your requests to imre@angelo.no and we will include it in the next update.

Super efficient - Run thousands of instances and experience improved performance.

Coroutine support - Simple Option Stacker can pause and resume coroutines just as easily as any other method.

Full argument support - Any behaviour is easily pushed with any number of arguments, which are efficiently stored and handled by Simple Option Stacker.

Easy implementation - Super easy to implement, seting up SFSM can be done in seconds, even in the largest of projects.

Multipurpose - The underlying Pushdown Automaton structure means Simple Option Stacker is perfect for Finite State Machines, as well as navigational menu screens, network protocols, and other asynchronous behaviors. You could use Simple Option Stacker for something totally unrelated aswell, like a deck of cards!

No dlls - There is no hidden code in this asset! All scripts are C#.

Still not impressed? This package comes with fully playable examples! (The RTS demo will return in 1.7)

Compatible with all versions of both Unity free and pro. Works on all known platforms?
