Question

当我调试项目时，我收到了222个警告，它只包含两个警告：

Warning: 1082: Migration issue: Method %s will behave differently in ActionScript 3.0 due to the change in scoping for the this keyword. See the entry for warning 1083 for additional information.

另一个：

Warning: 1008: return value for function '%s' has no type declaration

然后，我提供screenshot of warnings。我找到了esp Warning: 1082: Migration issue的解决方案，但遗憾的是，我什么也没找到。我读到了Warning: 1082: Migration issue，它说代码从AS2导入到AS3，但在我的情况下，我从不使用AS2。是的，我从另一个文件导入代码，但是在AS3中。我该如何解决这些错误？关于如何解决它的任何想法？任何建议或帮助将不胜感激。谢谢！

这是我的AS文件中的代码：

我已经评论了1082和1008中的一个警告。您认为这些警告的原因是什么？谢谢！

Answer 1

警告1008足够清楚;您的函数定义不包含返回类型声明。你的所有功能都没有返回任何东西，所以这是无害的。不过，要消除警告，您可以这样做：

public function start(event: MouseEvent):void {

取代

public function start(event: MouseEvent) {

如何修复Adobe Animate CC AS3中的警告1082（迁移问题）和1008？
