attachmovie, hitTest & multidimentional array question...

Hi all

I'm trying to make a game (my first) and I'm having trouble making my dynamically attached bullets and enemies collide. I've tried so many variations, tutorials, forum searches... to no avail.

Here's my code:

bulletArr = new Array();
var bulletCount = 0;
badArr = new Array();
var badCount = 0;
var badAmount = 0;
onEnterFrame = function() {
    if (Key.isDown(Key.SPACE)) {
        bulletCount ++; 
        var bulletName = bulletArr.push("bullet" + bulletCount);
        attachMovie("bullet", bulletName, bulletCount)
        this[bulletName]._y = random(Stage.height);
    }
    badAmount ++;
    if (badAmount > 50) {
        badCount ++;
        var badName = badArr.push("bad" + badCount);
        attachMovie("bad", badName, badCount);
        this[badName]._x = random(Stage.width);
        this[badName]._y = random(Stage.height);
        badAmount = 0;
    }
    this[bulletName].onEnterFrame = function() {
        this._x += 10;
        if (this._x > 560) {
            this.removeMovieClip();
        }
        for (i=0; i<badArr.length; i++) {
           if (this.hitTest(badArr)) {
                badArr._alpha -= 50;
            }
        }
    }
}

Any help is appreciated.

Thanks

badArr is an array of strings.  you need to help flash resolve those strings to movieclips using array notation  or, even easier just add the movieclip references to your arrays:


bulletArr = new Array();
var bulletCount = 0;

badArr = new Array();
var badCount = 0;
var badAmount = 0;

onEnterFrame = function() {
    if (Key.isDown(Key.SPACE)) {
        bulletCount ++; 
        var bulletName = "bullet" + bulletCount;
        var bmc:MovieClip = attachMovie("bullet", bulletName, bulletCount)
        bulletArr.push(mc);
        bmc._y = random(Stage.height);
    }
    badAmount ++;
    if (badAmount > 50) {
        badCount ++;
        var badName = "bad" + badCount;
        var mc:MovieClip = attachMovie("bad", badName, badCount);
        badArr.push(mc);
        mc._x = random(Stage.width);
        mc._y = random(Stage.height);
        badAmount = 0;
    }
    bmc.onEnterFrame = function() {
        this._x += 10;
        if (this._x > 560) {
            this.removeMovieClip();
        }
        for (i=0; i<badArr.length; i++) {
           if (this.hitTest(badArr)) {
                badArr._alpha -= 50;
                if(badArr._alpha<=0){
                   var mc:MovieClip = badArr;
                   badArr.splice(i,1);
                   mc.removeMovieClip();
                }
            }
        }
    }
}

Any help is appreciated.

Thank you soooooo much, I was pulling out my hair...

I'm really curious, do you help people here for the joy of teaching, or as a job? I don't mean to be rude/forward. Whatever the reason, it is very much appreciated.

Thanks
