Beehive at GitHup

Features:

• Allows you to write scripted Behaviour Trees that can be edited and reloaded at run time.
• Supports reading properties from your Agents (things controlled by the Behaviour Tree) using reflection
• Supports special coroutines which makes some more straight forward.
• Utility selectors, where a function describes the ordering of sub-tasks, instead of using the order in the script.
• A Lisp like scripting language for computing values, used in Utility tasks and optional tasks.

For information on Behaviour Trees, see Wikipedia: Behavior Trees (artificial intelligence, robotics and control).

I'm no good at writing sample / filler text, so go write something yourself.

Here's an example of a Behaviour Tree script, it's for a movie goer that;

• Runs to the exit if there's an alarm
• Goes to the bathroom if the need is great enough
• Watches the movie if everything is working out.

(BehaviourTree :RunningTaskHysterisis=10 
    (?
        (→  :if=IsAlarmOn /* Comments are allowed */     
            (→ 
                (GoToExit) 
                (Exit))
            (Panic :Message=""I can't find the exit!""))     
        (→  :if=(> BathroomNeed 0.8)
            (?
                (→ 
                    (GoToBathroom) 
                    (UseBathroom))
                (Panic :Message=""I can't find the bathroom!"")))
        (→
            (GoToCinema)
            (ReserveSeat)
            (GoToSelectedTile)
            (RunOnce 
              :Name=""Here's a name for you""
              (DebugLog (Format ""This seems {0} to be working {1}"" 1 5.5)))
            (StayInCenterOfSelectedTile))))

I'm releasing this code because I hope to use it to create my AI in upcoming Ludum Dares, and I invite you to try it out too!
