我一直在努力使用 Flash 预加载器。我只希望它用当前百分比更新屏幕上的文本。现在它基本上可以作为跟踪输出正确的百分比,但它不会更新我在屏幕上的文本字段。但是,一旦跟踪达到 100%,代码会在屏幕上输出“100”,但直到全部加载完毕。我没有 Flash IDE,只是在 FlashDevelop 中使用纯 Actionscript。这是我的代码:
package
{
import flash.display.Sprite;
import flash.events.Event;
import flash.display.Loader;
import flash.events.ProgressEvent;
import flash.net.URLRequest;
import flash.net.URLLoader;
import flash.display.Loader;
import flash.text.TextField;
import flash.text.TextFormat;
import flash.text.TextFieldType;
public class Main extends Sprite
{
public var myLoader:Loader = new Loader();
public var image:String = "tmp/Avengers-poster.jpg";
private var Title:TextField;
private var txt:String;
private var Form:TextField;
public function Main():void {
textbox("This is the title","box",100,100,200,30);
myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressStatus);
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaderReady);
var fileRequest:URLRequest = new URLRequest(image);
myLoader.load(fileRequest);
}
public function onProgressStatus(e:ProgressEvent):void {
// this is where progress will be monitored
var perc:int = Math.ceil((e.bytesLoaded/e.bytesTotal)*100);
txt = perc.toString();
Title.text = txt;
addChild (Title);
trace(perc);
}
public function onLoaderReady(e:Event):void {
// the image is now loaded, so let's add it to the display tree!
addChild(myLoader);
}
private function textbox (title_str:String,form_name:String,x:int,y:int,width:int,height:int):void {
Title = new TextField ();
Title.text = title_str;
Title.selectable = false;
Title.setTextFormat (new TextFormat ("Arial", 12, 0x777777, true));
txt = ".";
Title.x = x;
Title.y = y;
addChild (Title);
}
}
}
谢谢你的帮助。
