#Machine.js Make behaviour trees in JavaScript

v1.1 [see changelog]

By mary rose cook

##What is Machine.js?

Machine.js lets you use a hierarchical state machine to control a JavaScript object.

Define a behaviour tree as JSON.

{
      identifier: "idle", strategy: "prioritised",
      children: [
          {
              identifier: "photosynthesise", strategy: "sequential",
              children: [
                  { identifier: "makeEnergy" },
                  { identifier: "grow" },
                  { identifier: "emitOxygen" },
              ]
          },
          { identifier: "gatherSun" },
          { identifier: "gatherWater" },
      ]
  };

For each leaf state, define a function that enacts the behaviour for that state. So, for the gatherSun state, define a function that gathers sun.
For each state, define a can function that returns true if the actor may move to that state. So, for the gatherSun state, define a function canGatherSun that returns true if the sun is out.

##Licence

The code is open source, under the MIT licence. It uses Base.js by Dean Edwards.
