Loading the Panorama Actionscript 3.0
import flash.display.*;
import .URLRequest;
import flash.events.Event;
var loader:Loader = new Loader();
var url:String = "panorama.swf";
var urlReq:URLRequest = new URLRequest(url); var vr:MovieClip;// panorama movieclip
// This is done after the swf is loaded.
function finished_loading (e:Event){
}
function initHandler(event:Event):void{
trace("initHandler: "+ event);
vr = MovieClip(loader.content);// cast 'DisplayObject' to 'MovieClip'
// vr.isFlash10=false; // Disable Flash 10 rendering if the container is Flash 9
}
function initPanorama(e:Event){
// check if the panorama object is available and initialize it if((vr!=null)&&(vr.pano!=null)){
removeEventListener(Event.ENTER_FRAME, initPanorama);
vr.x=50;
vr.y=50;
vr.pano.setWindowSize(400,300);
}
}
// call initPanorama every frame
addEventListener(Event.ENTER_FRAME, initPanorama);
// Tell the loader to call 'finished_loading' after the swf is loaded. loader.contentLoaderInfo.addEventListener( PLETE, finished_loading);
// Tell the loader to call 'initHandler' after the swf is initialized. loader.contentLoaderInfo.addEventListener(Event.INIT, initHandler);
loader.load(urlReq);
addChild(loader);// add your swf directly to the stage
If you like to remove the panorama use the following code:
vr.cleanup();
removeChild(loader);
You need to call the cleanup method to avoid errors like "Cannot access a property or method of a null object reference" because ActionScript doesn't provide a destructor for objects. Actionscript 2.0
Only for Flash 8 export in Pano2VR 2.x - deprecated
var vr:MovieClip = _root.createEmptyMovieClip("vr", 1);
vr._lockroot=true;
// move the upper left corner
vr._x=100;
vr._y=200;
var myLoader = new MovieClipLoader();
var myListener = new Object();
myListener.onLoadStart = function(){
// Set the dimensions and position of the pano
vr.window_width=500;
vr.window_height=380;
vr.window_x=100;
vr.window_y=10;
};
myListener.onLoadInit = function(){
// your initalisation of the pano, add Hotspots,...
// You can also set the window size here but you need to use the API vr.pano.setWindowSize(500,380);
};
myLoader.addListener(myListener);
myLoader.loadClip("mypanorama.swf", vr);
I never managed to use loadMovie properly, so if you really want to use it you are on your own. The demo at
/samples/pano2qtvr/flashtour/ includes the .fla file with the complete source code. Panorama API calls
After the panorama is initialized and loaded you can make the following API calls at runtime
Changing the view
.pano.getPan();// returns the current pan angle
.pano.setPan(angle_in_degrees:Number);// sets the current pan angle
.pano.changePan(offset_in_degrees:Number);// change the current pan angle
.pano.getTilt();// returns the current tilt angle
