    local layer = cc.Layer:create()
    layer:setIgnoreAnchorPointForPosition(false)--(setAnchorPoint对layer没用)设置锚点为(0.5,0.5)，默认锚点在(0,0),

    local layerColor = cc.LayerColor:create(cc.c3b(255, 255, 255),width,height)--cc.c4b(255, 255, 255,255)
    layerColor:changeWidth(width)--Change width in Points.
    layerColor:changeHeight(height)--Change height in Points.
    layerColor:changeWidthAndHeight(width,height)--Change height in Points.
    layerColor:setContentSize(Size)--Sets the untransformed size of the node.

    local layerGradient = cc.LayerGradient:create(cc.c3b(255, 255, 255),cc.c3b(0,0,0),cc.p(1,1))--cc.c4b(255, 255, 255,255)

    local layerMultiplex = cc.LayerMultiplex:create(Layer_1,Layer_2,Layer_3...)
    local layerMultiplex = cc.LayerMultiplex:createWithArray(Vector)--Creates a LayerMultiplex with an array of layers.
    layerMultiplex:addLayer(Layer)--Add a certain layer to LayerMultiplex.
    layerMultiplex:switchTo(int)--int(从0开始），Switches to a certain layer indexed by n.
    layerMultiplex:switchToAndReleaseMe(int)--不能用release the current layer and switches to another layer indexed by n

    local function onNodeEvent(event)
    	if event == "enter" then--判断是否为退出层事件,enter
    		layer:unsheduleUpdate()--停止游戏调度
        elseif event == "exit" then
    	end
    end
    layer:registerScriptHandler(onNodeEvent)--注册层事件监听器
										--sprite也可以注册层级事件监听器
