Actionscript 3 为什么在我的代码中，当它试图显示一个对象（AS3）时会出现延迟？

我最近用as3写了一个flash程序。在项目的主类中，我有一个addChild方法，它给了我一些问题。问题是，当我运行这部电影时，孩子应该在舞台上展示，在渲染图像之前，时间会有很大的延迟

下面是主类中的代码：（下面是精确的代码行）

我尝试了不同的方法，但没有找到解决办法。我已经在另一台计算机上运行了该程序，但仍有延迟。 我只是想知道我的代码是否有问题，我必须修改，或者它是否是一个flash错误

谢谢你的阅读

是因为您将帧速率设置为0吗？我认为卡丁是正确的。“帧速率的有效范围为每秒0.01到1000帧。”-AS3参考。问题是，Flash的生命周期是：执行脚本-渲染帧-空闲-执行脚本-渲染帧-空闲-等等。如果设置低帧速率，脚本将变得无响应，并且每100秒会对您的任何交互做出一次响应。尝试将空闲帧速率设置为10。为什么

stage.frameRate=0？除了停止计时器外，如果您使用了Enter_Frame，那么您还应该删除那些
Enter_Frame
侦听器（稍后重新添加以恢复动画）是的。当帧速率过低时，刷新和响应能力会急剧下降。添加和删除enterframe事件监听器是非常好的选择。谢谢大家。我试着把听者移走，效果很好。再次非常感谢。：）
