-------預加載音樂

-------預處理開關
----讀取以前的設置
self.m_IsMusicOpen = GameInfo_Lua:getIntegerForKey_default("Music", 1) ----沒有讀取到，默認爲打開
self.m_IsEffectOpen = GameInfo_Lua:getIntegerForKey_default("Effect", 1) ----沒有讀取到，默認爲打開
end
----預加載背景音樂
function GamePlayMusicPlayer:preloadBackgroundMusic(filename)

end
----播放音效
----level聲音等級，當同時需要播放幾個聲音時，優先播放等級高的----暫定

----播放背景音樂
----一般情況下，請忽略notRecard參數，或者寫false
function GamePlayMusicPlayer:playBackgroundMusic(filename, notRecard)
if not notRecard then
----記錄最後改播放的music

end
----判斷是否要播放

end
end
end

------設置背景音開啓關閉狀態
function GamePlayMusicPlayer:setIsBackgroundMusicOpen(isOpen)
----內存修改

else self.m_IsMusicOpen = -1; end 
else

end
----記錄修改
local rt = 1;
if isOpen then rt = 1 else rt = -1 end

CCUserDefault:sharedUserDefault():flush();
----播放效果修改
if isOpen then
self:playBackgroundMusic(self.m_last_groundMusic, true);----播放最後應該播放的那個音樂，且不記錄
else
self:stopBackgroundMusic();----關閉當前音樂
end
end
