我遇到使用trace（）;
的问题例如，在我的项目（和其他项目）的多个点，我有跟踪语句，直到最近才起作用。由于某些原因，在之前工作的相同项目中，跟踪不再在“输出”窗口中显示任何内容。
我检查并完成了以下操作：
有没有人有任何想法？我添加了完整的代码。

查看代码的顶部，这是一个轻微的重新安排。在这个实验中，我冒昧地初始化你的'_FIELD'变量。试试吧。这会解决您的问题吗？
var mineField:Array = new Array;
var FIELD_H:int = 10;
var FIELD_W:int = 20;
for (var i:uint=0; i<FIELD_H; i++)
{
mineField[i]=new Array();
for (var j:uint=0; j<FIELD_W; j++)
{
mineField[i].push(0);
}
}
trace(mineField);

<强>第一
您的Main Class编写错误。如果已导入，则编译器应输出以下error message：
1114：public属性只能在包中使用。
因为类的一般形式是：
package myPackage
{
class MyClass
{
}
}
另一方面
具体而言，由于您可能尚未导入error message，因此未发生此Main class：
档案＆gt; ActionScript设置＆gt;文件类：Main
