答案 0 :(得分：1)
我不得不抱怨你的代码很乱。 您应该将代码重构为几个类，以减少重复的代码等。
关于问题。 有问题的一行就是这一行：
block.xSpeed = styles[index][i][j][1];
为了简单起见，我假设index，i和j为0。 我们来看一下样式的定义：
private var styles:Array = [
[
[0, //and so on
根据上述假设：
styles[0][0][0]是上面代码段中的数字0。将[1]添加到该行的末尾会尝试在此编号中查找属性1，该属性不存在。
不是无休止地将数组相互嵌套，而是构建最能描述数据的数据结构。 不要对原始数据进行操作，而是提供在数据结构中访问它的方法。
而不是map[i][j]，执行以下操作：map.get(i, j)这允许您自行测试此函数，在错误的参数值上抛出错误等。
我还建议将数据序列化/反序列化为对象。在某些数组中，您可以读取属性，而不是某些数字。这使代码更具可读性。
