[help] terrain hit

I'm trying to build a scrolling terrain with a hit test function but it won't work

code:

---

var tileW = 100;

function buildTerrain() {

        _root.attachMovie("empty", "world", 1);

        _root.world._y = 0;

        _root.world._x = 0;

        for (var i = 0; i<6; i++) {

                var thename = "t_"+i;

                _root.world.attachMovie("terrain", thename, i+1);

                _root.world[thename]._y = 350;

                _root.world[thename]._x = i*tileW;

                var type = math.floor(math.random()*10);

                _root.world[thename].gotoAndStop(type);

                //trace(type);

                _root.world[thename].onEnterFrame = function() {

                        this._x -= 5;

                        if (this._x<=-100) {

                                this._x += 600;

                                var type = math.floor(math.random()*10);

                                this.gotoAndStop(type);

                        }

                };

        }

}

buildTerrain();



_root.world.onEnterFrame=function(){

        _root.world._x-=_root.world.speed

        if (_root.world.hitTest(_root.chopper._x,_root.choppe  r._y,true)){

                _root.world.speed = 0 }}

where is my flaw at?

var type = math.floor(math.random()*10);
trace("type "+type);

That actually made a window open when I tested it that said output and generated a bunch of what seemed to be random numbers. that just kept generating

the trace was showing you what "type" came out to be, you were asking for a random number, and so it was giving it to you.

So do I need to change something or what?

_root.world._x-=_root.world.speed <--- ? => ;

Okay:
math.random:
Method; returns n, where 0 <= n < 1.

(It returns a Integer (element of N)).

math.floor:
Method; returns the floor of the number or expression specified in the parameter x. The floor is the closest integer that is less than or equal to the specified number or expression.

(It floors a Double (element of Q) to an Integer (element of N)).

-> You have an Integer which is element of N which you convert again to an Integer element of N with exactly the same value!

var tileW = 100;

	function buildTerrain() {

		_root.attachMovie("empty", "world", 1);

		_root.world._y = 0;

		_root.world._x = 0;

		for (var i = 0; i<6; i++) {

			var thename = "t_"+i;

			_root.world.attachMovie("terrain", thename, i+1);

			_root.world[thename]._y = 350;

			_root.world[thename]._x = i*tileW;

			var type = math.random()*10;

			_root.world[thename].gotoAndStop(type);

			//trace(type);

			_root.world[thename].onEnterFrame = function() {

				this._x -= 5;

				if (this._x<=-100) {

					this._x += 600;

					var type = math.random()*10;

					this.gotoAndStop(type);

				}

			};

		}

	}

	buildTerrain();

	_root.world.onEnterFrame = function() {

		_root.world._x -= _root.world.speed;

		if (_root.world.hitTest(_root.chopper._x, _root.chopper._y, true)) {

			_root.world.speed = 0;

		}

	};
