Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *params, &block) ⇒ Object

Creation through controls is usually done with an instance_eval of a block and this allows for a flexible interface.

Parameters:

  • name (String, Symbol) —

    the name or the alias of the control as it will be used within the course of the game.
