我是 as3 的新手，但我一直在学习。我正在创建一个带有文本字段输入的容器，以便用户可以创建一个“帖子”。当动画从舞台中移除时会触发此事件，它在完成后会自动执行。

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，因为用户很可能希望花费 2 分钟以上的时间来发帖。我一生都无法弄清楚为什么会发生这种情况，这可能是垃圾收集问题吗？

非常感谢您的任何帮助，谢谢，

您是否知道您的 alpha 增量器没有舍入问题？我会检查 alpha 的整数值，而不是真正的浮点值。或者，对一些小的 FUZZ 值进行模糊比较（alpha >= 1-FUZZ && alpha <= 1+FUZZ）。
