Field::StateManager Class Reference

#include <StateManager.hh>

Description

Base class that represents different "states" for an object.

Some objects inherit from this class in order to define unique behavior depending on what the current "state" of the object is. For example, FireSnakes may be falling from the sun, resting, or jumping. Each state has an "enter" and a "calc" function. The object that inherits this class is responsible for defining how many states there are and must specify the enter and calc functions for each of those states. The object is also responsible for defining the transition points (i.e. the criteria to move from one state to another).
