Adds a state machine to an entity. The entity is in one state at a time. Each state plays a Sequence when the entity enters the state and another when it leaves the state. StateMachineDef supplies the states and their sequences, and states supplies the map entities that each sequence plays on.

Initial state. When the component is created, the current state is the DefaultState of the EntityStateMachine. No sequence plays at that point.

State changes. State changes arrive from the server, each with the new state and the time at which it began. For each change, the client:

  1. stops the running exit sequence and plays the OutSequence of the current state;
  2. stores the new state and its start time;
  3. stops the running entry sequence and plays the InSequence of the new state, seeked to the time since the start time, and at least 0.

Activation. When the entity activates, the client plays the InSequence of the current state again, seeked the same way. An entity that activates late therefore joins the state at the point that the state has reached.

Object bindings. A sequence plays only if both EntityStateMachine.states and states have an entry for the state, and the entry in states has a binding list for the role (InSequence or OutSequence). Each binding names a selector of the sequence and a map entity by name. Before the sequence plays, the client binds each entity to its selector. Bindings whose entity does not exist are skipped.
