Re: [問題] FLEX中 mxml與as
經過C大的指點 我把程式做了修改，黃色是我做了修改的部份
※ 引述《forgot75421 (伏加特Ｉ》之銘言：
先說聲抱歉 我的中文實在是太差 講不出我所想表達的
所以我把我的程式碼貼上來
下面是mxml檔
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="vertical" fontSize="16" >
<mx:Script>
<![CDATA[
import mx.rpc.events.ResultEvent;
private var localstring:String="../amfphp/services/flex/box.dae";
當我在裡面填入localstring時是OK的 可以執行
private var obj3d:PV3D = new PV3D(localstring);
可是當我把它改成String(testvalue.text)就不能了
private var obj3d:PV3D = new PV3D(String(testvalue.text));
錯誤是 無法存取NULL物件的參考屬性或方法
private function PV3DModel():void{
this.PV3DArea.addChild(this.obj3d);
}
]]>
</mx:Script>
<mx:Button label="Button" click="PV3DModel()"/>
<mx:Label id="testvalue" text="../amfphp/services/flex/box.dae"/>
<mx:HBox width="100%" height="100%">
<mx:Panel width="100%" height="100%" title="PV3D">
<mx:UIComponent id="PV3DArea" width="100%" height="100%"/>
</mx:Panel>
</mx:HBox>
</mx:Application>
下面是as檔
package
{
import flash.display.Sprite;
import flash.events.Event;
import org.papervision3d.objects.parsers.DAE;
import org.papervision3d.view.BasicView;
public class PV3D extends Sprite
{
private var view:BasicView;
private var dae:DAE;
public var _localstring:String;
public function PV3D(st:String)
{
this._localstring=st;
init3D();
PV3DObject();
}
private function init3D():void{
view = new BasicView(0,0,true,true,"Target")
this.addChild(view);
this.addEventListener(Event.ENTER_FRAME, onEventRender3D)
}
private function onEventRender3D(e:Event):void{
dae.rotationY -= 5;
view.singleRender();
}
private function PV3DObject():void{
dae = new DAE();
dae.load(this._localstring);
dae.scale=5;
view.scene.addChild(dae);
}
}
}
我在想會不會是一開始load時它會先去跑Script然後才跑後面的程式??
