我正在尝试对一个在地图中移动的角色（perso）进行编程，生成一个数组。我的变量“t”调用了我的“Tuiles”MovieClip，创建了一个网格（格栅），在我的“地图”数组上每个“1”都有新的瓷砖。我首先用一个瓦片子修复了碰撞函数，所以，我创建了“地图”和“网格”函数。我需要“t”变量来创建世界和角色碰撞。如果我将变量放在我的函数“creeDecor”上，Flash 会生成它，但说我的碰撞函数不存在变量“t”。如果我将“t”变量作为一般变量放在我的代码顶部，Flash 会在舞台右下角生成一个平铺，碰撞功能运行良好......

我怎么能把它们混合两次？可能吗 ？

我让你我的整个代码。如果您希望它工作，您只需创建一个 MovieClip 类名称“Tuiles”（正方形：32*32）和第二个 MC“Perso”。

//Creation of perso

var perso:Perso = new Perso();

var grille:MovieClip = new MovieClip();

var t:Tuiles = new Tuiles();

var T:int = 32;

你想做很多不同Tuiles的事情，并检查每个人的碰撞。听起来您最初是在制作新Tuiles的creeDecor()，但除非您将新瓷砖存储在此之外，否则只creeDecor()知道它们。（这就是为什么 Flasht说不存在于collision().）这个关于函数范围的页面可能会有所帮助，如果您还没有阅读该文档的其余部分，那么它可能会有所帮助。

因此，您可能会Tuiles在顶层准备所有您的列表，例如：

var tList:Vector.<Tuiles> = new Vector.<Tuiles>();

这意味着两者都creeDecor()可以collision()看到tList。然后就像你以前做的那样，每次你需要一个新Tuiles的，并将它们添加到列表中：creeDecor()

if(f>0)  {
    var newT:Tuiles = new Tuiles();
    tList.push(newT);
    // Set up newT's position etc...

然后，您可以使用“for each... in”为每个Tuilesin运行命中测试tList

for each (var t:Tuiles in tList) {
    if (perso.hitTestObject(t))
        // Your collision code...
    }
}

如果你只有简单的方块，那么进行碰撞检测的方法可能比使用hitTestObject多次更快，因此如果速度较慢，调整它可能是一个很好的下一步。
