quick中用lua自定义Layer不调用onEnter的

Cocos2d-x Lua
#1

ocal PlayerLayer = class(“PlayerLayer”, function ()
return display.newLayer()
end)

function PlayerLayer:ctor()
print(“PlayerLayer:ctor”)
ui.newTTFLabel({text = “PlayerLayer”, size = 64, align = ui.TEXT_ALIGN_CENTER})
:pos(100, 100)
:addTo(self)
end

function PlayerLayer:onEnter()
self.super:onEnter()
print(“PlayerLayer:onEnter”)
– body
end

function PlayerLayer:onExit()
self.super:onExit()
print(“PlayerLayer:onExit”)
– body
end

function PlayerLayer:sayHello( )
– body
print(“PlayerLayer:sayHello”)
end

//…
scene:addChild( PlayerLayer.new())之后为什么不会调用onEnter,onExit函数呢？
