Trouble hitTesting an array.

[Vadersapien]

Hey everyone,
I am having trouble hitTesting items in an array...here is my full code:

stop();

var gameStarted:Boolean = false;
var gamePaused:Boolean = false;
var generateSpeed:Number = 7;
var speed:Number = 0;
var score:Number = 0;
var health:Number = 100;
var spiderArray:Array = [];

hud.pauseBar._visible = false;

menuSound.stop();
inGameSound.start();

this.createEmptyMovieClip('spiders',this.getNextHighestDepth());

this.onEnterFrame = function() {
    if (!gamePaused && gameStarted) {
        score++;
    }

    if (score == 1000 || score == 2000 || score == 3000 || score == 4000 || score == 5000) {
        generateSpeed += 3.5;
    }

    if (score == 6000) {
        generateSpeed = 28;
    }

    if (generateSpeed>28) {
        generateSpeed = 28;
    }

    if (health<0) {
        health = 0;
    }

    if (health == 0) {
        delete this.onEnterFrame;
        gameStarted = false;
        inGameSound.stop();
        gameOverSound.start();
    }
};

hud.onEnterFrame = function() {
    if (gameStarted && !gamePaused) {
        this.swapDepths(this.getNextHighestDepth());
    }
};

car.onEnterFrame = function() {
    if (gameStarted && !gamePaused) {
        if (Key.isDown(Key.UP)) {
            this._y -= speed/2;
        }

        if (Key.isDown(Key.DOWN)) {
            this._y += speed;
        }

        if (Key.isDown(Key.LEFT)) {
            this._x -= speed;
        }

        if (Key.isDown(Key.RIGHT)) {
            this._x += speed;
        }
        speed += 0.3;

        if (speed>=15) {
            speed = 15;
        }

        if (this._x<=37.35) {
            this._x = 37.35;
        }

        if (this._x>=762.65) {
            this._x = 762.65;
        }

        if (this._y<=42.65) {
            this._y = 42.65;
        }

        if (this._y>=507.40) {
            this._y = 507.40;
        }
        
        for(x in spiderArray){
            if (this.hitTest(_root[spiderArray[x]])) {
                _root[spiderArray[x]].removeMovieClip();
                this.removeMovieClip();
                spiderArray.splice(x, 1);
            }
        }
    }
};

grass.onEnterFrame = function() {
    if (gameStarted && !gamePaused) {
        this._y += speed;
    }

    if (this._y>0) {
        this._y = -200;
    }
};

spiderGenerator.onEnterFrame = function() {
    if (!gamePaused && gameStarted) {
        this._y -= generateSpeed;
    }

    if (this._y<0) {
        growSpider();
        this._y = 600;
    }
};

function growSpider() {
    if (!gamePaused && gameStarted) {
        spiderCount = 0;
        while (spiderCount<Math.floor(Math.random()*(9-7))+7) {
            spiderCount++;
            randomX = Math.floor(Math.random()*(745-55))+55;
            spider = spiders.attachMovie('Spider', 'Spider'+spiders.getNextHighestDepth(), spiders.getNextHighestDepth(), {_x:randomX, _y:-32});
            spiderArray.push(spider._name);

            spider.onEnterFrame = function() {
                if (!gamePaused) {
                    this._y += speed/2;
                    this.play();
                }

                if (this._y>=632) {
                    this.removeMovieClip();
                }
            };
        }
    }
}

function transitionToNextFrame() {
    nextFrame();
} 

Any ideas why it's not working?

Only thing that immediately sticks out is that wherever you have 'spiders' it should be:

"spiders"

Give that a try.

Tried it, but still no go...

Hard to tell then really mate without having the FLA. Hit testing with loops and such is always a bit of a funny one.

Unfortunately the only way you can find out what's going wrong is just by tracing stuff all over the place to see if it outputs what it should. Try tracing every 'x in spiderArray' for every iteration of your loop to see what it returns.

Also, trace when you push your new spiders into the array. The depths don't look quite right to me but I could be wrong. Just as a temporary sort of 'test', replace your attachMovie line with this:

spiders.attachMovie("Spider", "Spider"+spiderCount, spiderCount, {_x:randomX, _y:-32}); 

If that works you might not end up with the depths how you wanted but you'll have to play around with it. I've had a lot of problems before with getNetHighestDepth()+this+that etc. when attaching movies. Let me know how you get on.

I got it working eventually...it had to be:

 for(x in spiderArray){
            if (this.hitTest(_root.spiders[spiderArray[x]])) {
                _root.spiders[spiderArray[x]].removeMovieClip();
                spiderArray.splice(x, 1);
            }
        } 

Such a simple mistake...

Aha nice one. Yeah they always are!!

Good feeling when you finally overcome something like that and you can move on. Until something else goes wrong!
