Question

我正在尝试使用键盘移动生成的网格... 当我尝试我的.swf文件时，它运行但键盘... 这是一个像马里奥这样的平台游戏，所以你应该对那些没有感觉的代码行做好准备，但我向你保证会这样做！

所以，这是我的AS：

var map:Array = [
                 [1,1,1,1,1,1,10,0,0,11,1,1,1,1,1,1,1,1,1,1],

我现在看到几个问题：

paramMap及其内部函数movingGrid永远不会被任何人调用。您可能希望将它们挂钩到ENTER_FRAME事件侦听器，或者在用户按下某个键时调用它们。
vit的{{1}}和T属性不属于代码的这一部分，因此在测试时会抛出grid。同样适用于ReferenceError。

解决这些问题后，网格对象会正确移动。但是因为它是一个空的动画片段，你实际上还不能看到它。您需要向其添加可见子项或移动现有对象。这是剥离的代码，正确地向左和向右移动checkLateral：

grid

使用键盘移动生成的网格
