AS2 to AS3 help please (hints or anything)

[ghostly_1]

Hello everyone,

I am a huge noob in flash, I am to change a code from AS2 to AS3, this function (is a display tracking) should send a request for a server, and load the movie after, please tell me how to change it, some alternatives, some hints, but remember, keep the level low.

var EMISJE = "http://server.com/_"+Math.ceil(Math.random()*1000000000)+"/id=234"; 

_root.MAI_catchEmision = function(url) {
if (_root.MAI_catchEmision_run == undefined || _root.MAI_catchEmision_run == false) {
_root.createEmptyMovieClip("MAI_catchEmision_target_mc",_root.getNextHighestDep th());
_root.MAI_catchEmision_run = true;
_root.MAI_catchEmision_target_mc._x = Stage.width+10;
_root.MAI_catchEmision_target_mc._y = Stage.height+10;
_root.MAI_catchEmision_target_mc.loadMovie(url);
}
}

Thank you very much

I don't know what significance the first line has to the rest of the code, but it would not change.

var EMISJE = "http://server.com/_"+Math.ceil(Math.random()*1000000000)+"/id=234";

function MAI_catchEmision (url) {
if (MAI_catchEmision_run == undefined || MAI_catchEmision_run == false) {
  var MAI_catchEmision_target_mc:MovieClip = new MoiveClip();
  addChild(MAI_catchEmision_target_mc);
  MAI_catchEmision_run = true;
  MAI_catchEmision_target_mc._x = stage.stageWidth+10;
  MAI_catchEmision_target_mc._y = stage.stageHeight+10;
  var ldr:Loader = new Loader();
  var req:URLRequest = new URLRequest(url);
  var ldr.load(req);
  MAI_catchEmision_target_mc.addChild(ldr);
}
}

sorry fogot the last line:

_root.MAI_catchEmision(EMISJE);

so does this code work in AS3??

[Ned Murphy]

MAI_catchEmision(EMISJE);

What type of file is linked by that URL?  I have my doubts it would work even with AS2 if that is not an image or swf file.

[ghostly_1]

its an jpg file

[Ned Murphy]

I still have my doubts mainly because I  would epect to see a "jpg" somewhere at the end of that url in order for it to work, but if it somehow does deliver a jpeg image to the Loader, then it should work.  The only way to be sure is to try it, and that's up to you.

Thanks for your help,

I get only one error at the line:

  var ldr.load(req);

The error is:

1086: Syntax error: expecting semicolon before dot.

What could be done?

remove the var keyword

ldr.load(req);

By the way, you can add a Loader instance directly to the stage since it's a DisplayObjectContainer, rather than having to create a MovieClip instance first.

So this:

 var MAI_catchEmision_target_mc:MovieClip = new MoiveClip();
 addChild(MAI_catchEmision_target_mc);
 MAI_catchEmision_run = true;
 MAI_catchEmision_target_mc._x = stage.stageWidth+10;
 MAI_catchEmision_target_mc._y = stage.stageHeight+10;
 var ldr:Loader = new Loader();
 var req:URLRequest = new URLRequest(url);
 ldr.load(req);
 MAI_catchEmision_target_mc.addChild(ldr);

Can be reduced to:

  MAI_catchEmision_run = true;
  var req:URLRequest = new URLRequest(url);
  var ldr:Loader = new Loader();
  ldr.x = stage.stageWidth+10;
  ldr.y = stage.stageHeight+10;
  ldr.load(req);
  addChild(ldr);

read the docs on Loader:

http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/display/Loader.html

Also note that properties that had an underscore in AS2 no longer have one in AS3.

_x -> x

_y -> y

_width -> width

_height -> height

etc..
