Instance Method Details

#controls(*args) ⇒ Object

Example Usage: game.rb:

class Game < Shattered::Game
  def initialize
    ...
    player = Player.new # Where player includes Shattered::Model
    player.controls.on # this is the same as 'player.controls("player.controls").on'
  end
end

player.controls:

# command => condition
levitate => hold :a

# Note that both the command and the condition are instance_eval'ed

You can turn off an actor’s controls by calling:

player.controls.off

Controls default as off.

Note 1: Controls are only expected to be ‘method => action’ pairs, they are not meant logic at all, even though they can.

Note 2: Controls are meant to be user edittable - a user interface for defining keys.
