1、监听node的状态，比如创建释放等

self:registerScriptHandler(function(event)
        if event == "enter" then 
        
        elseif event == "exit" then 

        elseif event == "enterTransitionFinish" then 

        elseif event == "exitTransitionStart" then 

        elseif event == "cleanup" then 

        end 
end)

2、默认ProgressBar或者siler中的bar背景是缩放形式，如果要改成切割的话，setScale9Enabled(false)即可，如代码所示

local soundSiler = self.mView.soundSlider
soundSiler:setPercent(musicVolume * 100);
soundSiler:loadProgressBarTexture("creator/hall/Texture/SettingDialog/progressBar.png")
soundSiler:setScale9Enabled(false);
soundSiler:addEventListener(function(sender,event)
     local volume = sender:getPercent() / 100.0
     audio.setMusicVolume(volume)
end )

3、spine动画有黑边

第一步，spine导出时候把 “ 预乘Alpha” 取消勾选，然后再加上如下代码

方法一：

cc.Image:setPNGPremultipliedAlphaEnabled(false)

方法二

spineNode::setOpacityModifyRGB(true)

3、如果print没有输出的话

如果不重新编译模拟器的话 需要用release_print代替print...
