■[ruby][wii][cocoa]RubyとWiiリモコンをつなぐ

WiiRemoteFrameworkを使うにはCocoaの知識が必要だしメソッド名もCocoa的で

Rubyぽくないのでラッパーをつくった。

require 'osx/cocoa'
OSX.require_framework "WiiRemote"

class WiiRemo < OSX::NSObject
  @@instance = nil
  def self.start_search(&found_block)
    raise "already initialized" if @@instance
    @@instance = WiiRemo.alloc.init(&found_block)
    puts @@instance.inspect
  end
  def self.stop_search
    @@instance.stop
    @@instance = nil
  end

  def initialize
    @discovery = nil
  end

  def init(&found_block)
    @discovery = OSX::WiiRemoteDiscovery.alloc.init
    @discovery.setDelegate(self)
    @found_block = found_block
    @discovery.start
    return self
  end
  
  def stop
    @discovery.stop
  end

  def WiiRemoteDiscovered(remote)
    puts "WiiRemoteDiscovered remote=#{remote.inspect}"
    remote_proxy = RemoteProxy.alloc.init(remote)
    @found_block.call(remote_proxy)
  end

  def WiiRemoteDiscoveryError(code)
    #puts "WiiRemoteDiscoveryError code=%x" % code
  end

  ## WiiRemoteDiscovery callback
  objc_method :WiiRemoteDiscovered,     %w{void id}
  objc_method :WiiRemoteDiscoveryError, %w{void int}
  
  class RemoteProxy < OSX::NSObject
    def init(remote)
      @remote = remote
      @remote.setDelegate(self)

      when 1: @client.nuncyaku_acc(ax, ay, az)
      else raise "unknown acc type #{type}"
      end
    end

    def joyStickChanged_tiltX_tiltY_wiiRemote(type, tilt_x, tilt_y, wiiRemote)

ODEにつなごうとしたんだけどQuaternionがわからなくて飽きてしまった！！
