cocos2dx+lua 键盘监听事件

local MainScene = class("MainScene", cc.Node)
function MainScene:ctor()
	self:KeyboardEvent()
end


function MainScene:KeyboardEvent()  
	--键盘按键按下回调函数
    local function keyboardPressed(keyCode, event)  
        print(keyCode)--输出keycode
    end 

	--键盘按键松开回调函数
    local function keyboardReleased(keyCode, event)

    end
    --注册键盘监听事件
    local listener = cc.EventListenerKeyboard:create()  
    --绑定回调函数
    listener:registerScriptHandler(keyboardPressed, cc.Handler.EVENT_KEYBOARD_PRESSED)  
    listener:registerScriptHandler(keyboardReleased, cc.Handler.EVENT_KEYBOARD_RELEASED)  
    local eventDispatcher = self:getEventDispatcher()  
    eventDispatcher:addEventListenerWithSceneGraphPriority(listener, self)  
end
