编辑：当游戏开始时，LV1介绍文本开始。一旦scrollV等于maxScrollV，就会出现下一个按钮。点击它，它将自行删除并开始游戏。一旦你击败第一阶段，levelNum自动等于2，我再次从我的主文档类添加这个类。但是，它会反复显示相同的文本，无论级别如何。
urlLoader也始终保持不变？如果是这样，我该怎么改呢？
答案 0 :(得分：1)
可以重复使用URLLoader来使用新的URLRequest实例加载其他数据。重复使用相同的URLLoader实例来加载另一个文件是完全可以的。您的问题不在URLLoader中，而是在逻辑或其他地方。您最好尝试使用调试器来确保变量级别的值正确为2。
::::::::: EDITED :::::::::
您正在clickNext（）调用中从textLoader中删除事件侦听器。 textLoader将加载文件，但不会运行onLoaded（）来更新textBox.text
你的speechBoxCheck（）方法做错了。 1.你必须在speechBox（）方法中只进行1次load（）调用。方法中的条件不是独占的，并且在进行多次load（）调用时可能会导致问题（先前的加载操作将被取消）。考虑“其他如果”链。
建议不要以这种方式加载文件。应避免不必要的I / O操作，尤其是在运行时。仅在需要时加载文件;在这种情况下，它是在级别更改时。
