Actionscript 3 使用键盘从阵列中移动贴图,actionscript-3,flash,Actionscript 3,Flash,我想创建一个带有数组的地图。。。我在flash上看到了很多关于平台游戏creatio的教程，但是没有一个人在移动地图所以，我试着自己做。在移动地图之前，我必须创建它，这是我的问题！所以，我让你们看一看三层代码，并提出你们的意见 Flash向我宣布一个错误#1009，他无法访问空对象引用的属性或方法，而我一次也看不到 at Sansnom_fla::MainTimeline/createMap() at Sansnom_fla::MainTimeline/frame1() 第一层 var

我想创建一个带有数组的地图。。。我在flash上看到了很多关于平台游戏creatio的教程，但是没有一个人在移动地图

所以，我试着自己做。在移动地图之前，我必须创建它，这是我的问题！所以，我让你们看一看三层代码，并提出你们的意见

Flash向我宣布一个错误#1009，他无法访问空对象引用的属性或方法，而我一次也看不到

at Sansnom_fla::MainTimeline/createMap()
at Sansnom_fla::MainTimeline/frame1()

第一层

var grid:MovieClip = new MovieClip();   

// liste d'affichage
addChild(grid)                      

createMap()

第二层

function createMap():void{
    for (var i:int=0; i<20; i++){                               
        for (var j:int=0; j<15; j++){                           

            var T:int = 32
            var dT:int = T*.5
            var f:int = map[j][i]

            if(f>0) {
                var t:block = new block()
                t.x= i*T;       
                t.y= j*T;       
                t.gotoAndStop(f)        
                grid.addChild(t)
            }
        }
    }
}

非常感谢！

Ps：正如您所了解的，块是一个movieClip，其中一个帧是一个特定的块。

为什么要在层之间拆分代码？不要那样做。另外，在第2层中调用

map

，它甚至还没有出现（直到第3层的代码运行后才创建），所以我的建议是将它全部粘贴到1层，在1帧上

然后调整代码顺序，如下所示：

var map:Array = [
