我想用数组创建一个地图...我在flash上​​看到很多关于平台游戏创建的教程，但没有人用地图移动。

所以，我试着自己做。在移动我的地图之前，我必须创建它，这就是我的问题！所以，我让你看看三层代码并发表你的意见。

Flash 通知我一个错误 #1009，他无法访问空对象引用的属性或方法，我一次也看不到？

非常感谢 ！Ps：正如你所了解的，block 是一个movieClip，其中一帧是一个特定的块。

为什么要在层之间拆分代码？不要那样做。map此外，您甚至在第 2 层还存在之前就调用了它（直到第 3 层的代码运行后才创建它）所以我的建议是将它全部粘贴到 1 层的 1 帧上。

然后像这样调整您的代码顺序：

var map:Array = [
                 [1,1,1,1,1,1,10,0,0,11,1,1,1,1,1,1,1,1,1,1],
                 [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
                 [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
                 [1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,7,0,1],
                 [1,0,0,0,0,0,6,1,0,0,4,4,4,4,0,0,6,1,0,1],
                 [1,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
                 [1,0,0,0,1,6,0,0,0,0,0,0,0,0,0,0,0,0,0,1],
                 [1,0,0,0,0,6,0,0,0,0,0,0,0,0,0,0,0,0,0,1],

                grid.addChild(t)

        }
    }
}

var grid:MovieClip = new MovieClip();   

// liste d'affichage
addChild(grid);

createMap();

也不要忘记;角色，你有错过他们的习惯。无论如何，希望这会有所帮助！
