Actionscript works in one frame but not the other...?

[iamali]

Hi all,

I'm working on this electronic sheep creator for my Masters degree (don't ask haha..) which is online at www.aegreen.co.uk/creativetech/ . The problem I'm having is that a piece of actionscript I'm using for saving the sheep as a jpg using BitmapData works in one frame with one movie clip but not in another frame..

In frame 1 I create two movie clips - mc_modifysheep and mc_dna:

on(release) {
	_root.createEmptyMovieClip("mc_modifysheep", 1)
		mc_modifysheep._x = 150;
		mc_modifysheep._y = 70;
		mc_modifysheep.attachMovie("sheep_body", "body", 1, {_x:42, _y:65});
		mc_modifysheep.attachMovie("sheep_head", "head", 2, {_x:0, _y:0});
		mc_modifysheep.attachMovie("sheep_legs", "legs", 3, {_x:77, _y:215});
		_global.bodycolour = "default";
		_global.headcolour = "default";
		_global.legscolour = "default";

	_root.createEmptyMovieClip("mc_dna", 2)
		mc_dna._x = 0;
		mc_dna._y = 0;
		mc_dna.attachMovie("mc_DNA_empty", "DNA empty", 1, {_x:8, _y:360});
		mc_dna.attachMovie("mc_dna_default_default_top", "top", 2, {_x:45, _y:374});
		mc_dna.attachMovie("mc_dna_default_default_right", "right", 3, {_x:65, _y:400});
		mc_dna.attachMovie("mc_dna_default_default_left", "left", 4, {_x:32, _y:401});
	
	gotoandstop(2);
}

the sheep in 'mc_modifysheep' and the dna in 'mc_dna' are built up over frames 2 and 3 and then in frame 4 the user decides whether the sheep is given freedom or captivity. If freedom is chosen then the user is prompted to name their sheep and the movie clip mc_modifysheep is saved as a jpg on the server using BitmapData and PHP. If captivity is chosen then the user is prompted to name the dna and the movie clip mc_dna is meant to be saved as a jpg on the server but only a white blank jpg is produced, not what is contained in mc_dna.. I've tried all sorts but I can't figure out why it's doing this..

Here's the code I'm using, that works, to save the mc_modifysheep:

import flash.display.BitmapData;
btn_freedom.onPress = function() {
	freedom();
};

function freedom() {
	snap_sheep = new BitmapData(305, 290);
	snap_sheep.draw(mc_modifysheep);

	var pixels:Array = new Array();
	var w:Number = snap_sheep.width;
	var h:Number = snap_sheep.height;
	var a:Number = 0;
	
	var sn:String = txt_Freedom.text;
	high = 99999;
	low = 00000;
	ran = Math.floor(Math.random()*(Number(high)+1-Number(low)))+Number(low);
	var rn:Number = ran
	var filename:String = dn+sn;

		for (var a = 0; a <= w; a++) {
			for (var b = 0; b <= h; b++) {
						var tmp = snap_sheep.getPixel(a, b).toString(16);
						pixels.push(tmp);
			}
		}
		
	var freedomoutput:LoadVars = new LoadVars();
	freedomoutput.img = pixels.toString();
	freedomoutput.height = h;
	freedomoutput.width = w;
	freedomoutput.filename_sheep = filename;
	freedomoutput.send("save_sheep.php", "_self", "POST");
}
stop();

and here's the near identical code apart from different variable/movieclip names I'm using to try and save (but failing) mc_dna:

import flash.display.BitmapData;
btn_capt.onPress = function() {
	capt();
};

function capt() {
	snap_dna = new BitmapData(305, 290);
	snap_dna.draw(mc_dna);

	var pixels:Array = new Array();
	var w:Number = snap_dna.width;
	var h:Number = snap_dna.height;
	var a:Number = 0;
	
	var dn:String = txt_Capt.text;
	high = 99999;
	low = 00000;
	ran = Math.floor(Math.random()*(Number(high)+1-Number(low)))+Number(low);
	var rn:Number = ran
	var filename:String = dn+rn;

		for (var a = 0; a <= w; a++) {
			for (var b = 0; b <= h; b++) {
						var tmp = snap_dna.getPixel(a, b).toString(16);
						pixels.push(tmp);
			}
		}
		
	var captoutput:LoadVars = new LoadVars();
	captoutput.img = pixels.toString();
	captoutput.height = h;
	captoutput.width = w;
	captoutput.filename_dna = filename;
	captoutput.send("save_dna.php", "_self", "POST");
}
stop();

I know it's a problem with the flash and not the PHP as I've tested for that, definately in the flash. I just don't understand how the same code can capture mc_modifysheep, but not mc_dna. argh!!!

If you need to take a look at the FLA file it's up at www.aegreen.co.uk/creativetech/dohumansdream.fla

Thanks everyone!!

Could it be that you're importing BitmapData twice?

ooh, so i should only import it on the first frame and not the second? i'll try that

nope it hasn't worked removing one of them
