Question

我试图编辑这个糟糕的蛇版动作脚本，用作我正在使用的网站中的娱乐内容。我的问题是1010错误，对我来说似乎没有意义。我试过调试没有成功。

显示的第一个输出内容如下：

对于可以在运行时编辑的任何文本，应嵌入字体，而不是使用＆＃34;使用设备字体＆＃34;设置。使用文字＆gt;字体嵌入命令嵌入字体。

每当我的蛇吃食物（可以这么说）时，我都会收到错误：

TypeError：错误＃1010：术语未定义且没有属性。在Main / onEnterFrame（）

完整的代码是：

基于我们的谈话，这似乎是解决方案

对于字体，找到动态的文本字段，然后在属性面板中选择嵌入，然后检查您需要嵌入的字符，否则它们可能不会在运行时显示
运行时1010错误，在你的onEnterFrame方法中，似乎有一个空参数：head，stage，snake或txtScore。
