当我正常播放lvl1我的Array版本时，如果我想在其他级别之后执行，则不会构建任何内容。如果我想做其他级别，即使我不执行lvl1，也只构建我的Array的前5列。并且，为了完成，当我完成计时器时，我有这个错误：

这是我的第4帧代码：
import flash.events.MouseEvent;
ScoreFin.text = points.toString();
btnMenu.addEventListener (MouseEvent.CLICK, retourMenu);
function retourMenu (e:MouseEvent):void{
gotoAndStop(2);
}
修改 根据OP的评论：
我有不同级别（LVL2，LVL3，LVL4），当我执行我的函数lvl2，lvl3，{时，这些级别未正确初始化循环中的{1}}范围为lvl4 frame 3。
不是创建数组，而是只创建前五列，而不创建其余列。
答案 0 :(得分：1)
一：您已在级别创建的所有功能中对tableau1进行了硬编码，包括collisions。
二：你在hittest事件上删除tableau1。
三：如果您当前的帧不是3，则您的Pac对象未定义，因为布局被写为关键帧，但您不会删除所有以Pac为目标的侦听器，只删除一个那是附在碰撞块上的。
四：构建数组时，其长度为5，但是您将行和列从0迭代到长度为1，导致您的级别只有5列。相反，您需要在tableau1[0].length之前运行内循环，就像在collisions中一样。
您确实需要学习调试代码，并跟踪调用的内容和来自哪里。
