bitmapdata problem

[NoSkills]

i don't know why my line width doesn't decrease after my fertig flag is set to 1

here's what it looks like:
http://ize.badne.ws/meh/worm.swf

and the fla:
http://ize.badne.ws/meh/worm.fla

if thickness is above 70 it sets the fertig flag to 1 and then SHOULD decrease the line width again... it doesn't though.... i have no idea why because the thickness variable IS decreased

the (crappy) code:

//when fertig is 1 and thickness is still over 10 it should decrease the width again...
//it doesn't tho :(

var worm:Sprite = new Sprite();
addChild(worm);
worm.graphics.lineStyle(3,0xff0000);
worm.x=300;
worm.y=0;

var ypos:int=0;
var xpos:int=0;
var thickness:Number=1;

var bmap=new flash.display.BitmapData(600,400,true,0x00000000);

var fertig:Boolean=0;

var myMatrix:Matrix = new Matrix ();

var tempBitmap:Bitmap=new Bitmap(bmap);
stage.addChild(tempBitmap);

myMatrix.translate(300-(thickness/2),0);

var myRandom:Number;

stage.addEventListener(Event.ENTER_FRAME, gameloop);
function gameloop(myevent:Event):void {
    myRandom=5*Math.random();
    worm.cacheAsBitmap=true;
    tempBitmap.cacheAsBitmap=true;
    if (fertig!=1) {
        worm.graphics.lineStyle(2,0x00ffff);
        worm.graphics.lineTo(xpos+thickness+myRandom,ypos);
        
        thickness+=0.5;
        trace(thickness);
        bmap.draw(worm,myMatrix);
        myMatrix.translate(-myRandom+2.25,0);
        bmap.scroll(0,1);
    } else {
        if (thickness>10) {
            trace(thickness)
            worm.graphics.lineStyle(2,0x00ff00);
            worm.graphics.lineTo(xpos+thickness+myRandom,ypos);
            thickness-=0.5;
            bmap.draw(worm,myMatrix);
            myMatrix.translate(-myRandom+2.25,0);
            bmap.scroll(0,1);
        } else {
            tempBitmap.y+=1;
        }
    }
    
    if (thickness>70) {
        fertig=1;
    }
    
    worm.graphics.clear();
}

You are giving a Boolean var a numerical value. You have to give it the value false or true.

0 means false in boolean
1 means true
so my code is correct in that part

[cancerinform]

not in Flash. You get a warning. But you are right, fixing that does not solve the problem.

I have played around with that script. I think what is happening is that once the line has a certain length like 70 px or 100 px it stays that way and is not cleared.
