我正在尝试编写一个在地图中移动的角色（perso），并使用数组生成。 我的变量“t”调用了我的“Tuiles”MovieClip，在我的“map”数组上创建了一个网格（格栅），每个格子都为“1”。 我首先使用一个tile Child修复了碰撞功能，因此，我创建了“map”和“grid”函数。我需要世界创造的“t”变量和角色碰撞。 如果我将变量放在我的函数“creeDecor”上，Flash会生成它很好但是我的碰撞函数不存在变量“t”。 如果我将“t”变量放在我的代码之上作为一般变量，Flash会在舞台的右下方生成一个平铺，碰撞功能正常...
我怎么能把它们混合两次？ 有可能吗？
我告诉你我的整个代码。如果你想要它工作，你只需创建一个MovieClip类名称“Tuiles”（方形：32 * 32）和第二个MC“Perso”。

答案 0 :(得分：1)
你想要制作许多不同的Tuiles，并检查每一个的碰撞。听起来你最初在Tuiles中制作了新的creeDecor()，但除非你将新的瓷砖存储在其中，否则只有creeDecor()知道它们。 （这就是为什么Flash说t collision()中不存在Tuiles。）This page about Function scope可能会有所帮助，如果你还没有阅读它，那么该文档的其余部分也是如此。< / p>
因此，您可以在顶层准备一份所有var tList:Vector.<Tuiles> = new Vector.<Tuiles>();
的列表，例如：
creeDecor()这意味着collision()和tList都可以看到Tuiles。然后就像之前一样，每次需要时在creeDecor()中创建新if(f>0) {
var newT:Tuiles = new Tuiles();
tList.push(newT);
// Set up newT's position etc...
，然后将它们添加到列表中：
Tuiles然后，您可以使用"for each... in"
为tList中的每个for each (var t:Tuiles in tList) {
if (perso.hitTestObject(t))
// Your collision code...
}
}
运行您的点击测试
hitTestObject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{{1}}多次更快，所以如果它很慢，那么调整它可能是一个很好的下一步。
