Ekstern Loader

Load presentation

Tilgængelige variabler defineret øverst.
I en class, skal de stå i class definitionen, før constructer’en (hoved-functionen).

var film1:URLRequest = new URLRequest("undermappenavn/anim_playback.swf");
var film2:URLRequest = new URLRequest("undermappenavn/bat_ball_2a.swf");
var film3:URLRequest = new URLRequest("undermappenavn/fruit_extra_new_b.swf");

I en class, vil denne typisk stå i constructor’en:

var ldr:Loader = new Loader();

I nedenstående script loades og vises hver film i hver sin knap-funktion:

film1_but.addEventListener(MouseEvent.MOUSE_DOWN,film1_Handler);
function film1_Handler(e:MouseEvent):void {
    SoundMixer.stopAll();
    ldr.load(film1);
    box_mc.addChild(ldr);
    stage.frameRate=12;
}
film2_but.addEventListener(MouseEvent.MOUSE_DOWN,film2_Handler);
function film2_Handler(e:MouseEvent):void {
    SoundMixer.stopAll();
    ldr.load(film2);
    box_mc.addChild(ldr);
    stage.frameRate=32;
}
film3_but.addEventListener(MouseEvent.MOUSE_DOWN,film3_Handler);
function film3_Handler(e:MouseEvent):void {
    SoundMixer.stopAll();
    ldr.load(film3);
    box_mc.addChild(ldr);
    stage.frameRate=32;
}

Nedenstående knap-funktioner tømmer loaderen, ændrer boksens egenskaber, og til sidst ‘taler’ direkte til den loadede swf’s egen tidslinie :

unload_but.addEventListener(MouseEvent.MOUSE_DOWN,unload_Handler);
function unload_Handler(e:MouseEvent):void {
    SoundMixer.stopAll();
    ldr.unloadAndStop();
    stage.frameRate=12;
}
distort_but.addEventListener(MouseEvent.MOUSE_DOWN,distort_Handler);
function distort_Handler(e:MouseEvent):void {
    box_mc.scaleX = box_mc.scaleY = .6;
    box_mc.rotation=9;
}
normal_but.addEventListener(MouseEvent.MOUSE_DOWN,normal_Handler);
function normal_Handler(e:MouseEvent):void {
    box_mc.scaleX = box_mc.scaleY = .6;
    box_mc.x = 180;
    box_mc.y = 64;
    box_mc.rotation=0;
}
cheat_but.addEventListener(MouseEvent.MOUSE_DOWN,cheat_Handler);
function cheat_Handler(e:MouseEvent):void {
    MovieClip(ldr.content).gotoAndStop("win");
/*
tilsvarende, kaldt fra den loadede swf's tidslinie, ville være:
//////////
MovieClip(parent.parent).play();
/////////
*/
}

Preloader ekstern

Den nemmeste relaterede tutorial – er nok denneher:
monkeyflash.com/flash/creating_a_custom_preloader

var ldr:Loader = new Loader();
 
ldr.load(new URLRequest("content.swf"));
 
ldr.contentLoaderInfo.addEventListener(Event.OPEN, loadOpen);
ldr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);
ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
 
function loadOpen(e:Event):void {
    trace("Loading begun");
} 
 
function loadProgress(e:ProgressEvent):void {
    var percentLoaded:Number = e.bytesLoaded/e.bytesTotal;
    percentLoaded = Math.round(percentLoaded * 100);
    trace("Loading: "+percentLoaded+"%");
}
 
function loadComplete(e:Event):void {
    addChild(ldr);
    trace("Complete");
}

Knapper i array

Edited 16 March 2011 • admin TOC • be the first to comment 
var files:Array=new Array("0.swf","1b.swf","3_load text_scroller.swf");
var buts:Array=new Array("but1","but2","but3");
// buts[0] er "but1", buts[1] er "but2", osv.

Her kan loader funktionaliteten indflettes

for (var b:uint; b<buts.length; b++) {
	var but:Object=getChildByName(buts[b]);
	but.addEventListener(MouseEvent.CLICK, butClick);
	// hver but får sin egen variabel:fil med tilknyttet filnavn
	but.fil="eventuel_undermappe/"+files[b];
}
function butClick(e:MouseEvent) {
        SoundMixer.stopAll();
	ldr.load(new URLRequest(e.target.fil));
}
