节能的Flash（AS3）数据到XML

问题描述

我一直都在interwebs，包括堆栈溢出，几个小时，试图找出信息保存在Flash转换为XML文件的一个坚实的，可行的例子。

I've been all over the interwebs, including Stack Overflow, for hours, trying to identify a solid, workable example of saving information in Flash into an XML file.

我想采取两种不同类型的对象的位置和每个列表导出到XML。我们将调用对象的球和蝙蝠

I want to take the positions of two different types of objects and export the lists of each to XML. We'll call the objects ball and bat.

所以，我很想有XML的样子是这样的：

So, I'd love to have the XML look something like:

<objects>
    <ball xPos=34 yPos=43/>
    <ball xPos=12 yPos=94/>
    <bat xPos=1 yPos=39/>
</objects>

听起来很简单，但我一直没能找到一个体面的例子正是AS3 code能做到这一点。这些数据是在影片剪辑的两个向量，所以我会用球棒[I] .X和蝙蝠[I] .Y输入值。

Sounds simple enough, but I haven't been able to find a single decent example for exactly what AS3 code can accomplish this. The data is in two vectors of MovieClips, so I'd be using bats[i].x and bats[i].y for input values.

我怎样才能创建这个XML，并将其保存在某处地方查看？感谢您的所有帮助，这已经被证明非常令人沮丧。

How can I create this XML, and save it somewhere local to view? Thank you for any help at all, this has proved extremely frustrating.

推荐答案

与XML在AS3工作是很容易，所以要扩大TheDarkIn1978的一些code答案：

Working with XML in AS3 is really easy, so to expand on TheDarkIn1978's answer with some code:

创建XML对象：

var objs:XML = new XML( <objects /> ); // create the <objects /> node

// for your objects
var ball1:XML = new XML ( <ball /> ); // create the <ball /> node
ball1.@xPos = 12; // add 12 as an attribute named "xPos"
ball1.@yPos = 42; // add 42 as an attribute named "yPos"
objs.appendChild( ball1 ); // add the <ball> node to <objects>

// an example of using variables in your xml
var name:String = "something";
var sx:XML = new XML( <{name} /> ); // creates a node <something />

使用的TheDarkIn1978的到 XML 类AS3了解更多信息。

保存您的文件：

// saving out a file
var f:FileReference = new FileReference;
f.save( sx, "myXML.xml" ); // saves under the name myXML.xml, "sx" being your root XML node

的COM $ P $保存前pssing你的XML（有大的XML文件，这样可以节省大量的）：

Compressing your XML before saving (with large XML files, this can save a lot):

// compressing before saving
var f:FileReference = new FileReference;

var bytes:ByteArray = new ByteArray;
bytes.writeUTFBytes( myXML ); // "myXML" being your root XML node
bytes.compress(); // compress it

f.save( bytes, "myXML.xml" );

装载在COM pressed XML，uncom pressing它，并检索XML对象：

Loading in a compressed XML, uncompressing it, and retrieving the XML object:

// uncompressing a compressed xml
var loader = new URLLoader;
loader.dataFormat = URLLoaderDataFormat.BINARY;

// listen for our events
loader.addEventListener( Event.COMPLETE, this._onLoad );
loader.addEventListener( IOErrorEvent.IO_ERROR, this._onFail ); // not shown
loader.addEventListener( SecurityErrorEvent.SECURITY_ERROR, this._onSecurityError ); // not shown

private function _onLoad( e:Event ):void
{
    var loader:URLLoader = e.target as URLLoader;

    // get the data as a bytearray
    var ba:ByteArray = loader.data as ByteArray;

    // uncompress it
    try
    {
        ba.uncompress();
    }
    catch ( e:Error )
    {
        trace( "The ByteArray wasn't compressed!" );
    }

    // get our xml data
    myXML = XML( ba );
}

我创建了COM pressing / uncom pressing XML文件的简单工具。你可以得到的SWF和源的<一个href="http://divillysausages.com/blog/xml_com$p$pssor_uncom$p$pssor">http://divillysausages.com/blog/xml_com$p$pssor_uncom$p$pssor如果你有兴趣
