Actionscript 3 AS3物体在1.5-2分钟后莫名其妙地消失

我是as3新手，但一直在学习。 我正在创建一个带有文本字段输入的容器，这样用户就可以创建一个“post”。当动画从舞台移除时会触发此操作，动画完成后会自动执行此操作

然而，大约1.5-2分钟后，容器莫名其妙地消失了。这是一个问题，因为用户可能需要花费2分钟以上的时间来发表文章。 我一辈子都搞不清楚为什么会发生这种情况，这可能是垃圾收集的问题吗

非常感谢您的帮助，谢谢

丹

你知道你的alpha递增器没有舍入问题吗？我将检查alpha的整数值，而不是实际的浮点值。或者，模糊比较alpha>=1-fuzz&&alpha是否使用此函数同时创建多篇文章？我明白你关于垃圾收集的观点，但它不应该删除stage元素，因为你声明了变量，它应该足以保护它免受垃圾的影响……alpha值在增加，所以即使条件没有触发，这也不应该是他的问题。无论如何，总的来说，这是一件好事。
