一个概念类似于AS3指针？ [英] a concept similar to pointers in as3?

问题描述

是否有指针的一个概念或任何类似于AS3？

Is there a concept of pointers or anything similar to that in as3?

我已经使用的概念

var mc1:MovieClip;
var mc2:MovieClip();
var mcCommon:MovieClip = new MovieClip();
mcCommon["myptr"] = mc1;
mcCommon["myptr"] = mc2;

我会在哪里去阅读和了解更多关于这个概念。我想获得简单的答案，因为我不是在AS3的专家。我仍然在学习。

Where would I get to read and learn more about this concept. I'd like to get simple answers, as I am not an expert in as3. I'm still learning.

推荐答案

如果你特别问的是code，首先它应该是这样的：

If you are asking specifically about the code, first of all it should look like this:

var mc1:MovieClip;
var mc2:MovieClip;
var mcCommon:MovieClip = new MovieClip();
mcCommon["myptr"] = mc1;
mcCommon["myptr"] = mc2;

虽然两个MC1和MC2实际上是空。

Though both mc1 and mc2 are actually null.

语法mcCommon [myptr]是指您创建一个名为myptr的影片剪辑mcCommon财产。所以，你可以在以后检索该属性的使用mcCommon [myptr]的内容。最后一行实际上将覆盖该属性的内容（如果它不是空，当然）。你可以这样做，因为MovieClip类是动态的。在其他（非动态）情况下，你不能像这样创建的属性。

The syntax mcCommon["myptr"] means that you create a property named "myptr" on MovieClip mcCommon. So you can later retrieve the content of this property using mcCommon["myptr"]. The last line actually overwrites the content of the property (if it wasn't null of course). You can do that because MovieClip class is dynamic. On other (non-dynamic) instances you can't create properties like this.
