I’m stumped with a problem I’m having with hitTest. I got the object to move around using the arrow keys, and in one test I got the object to stick to a wall and not move, but I changed some code around and now it doesn’t recogize the hitTest at all.

```auto
if (key.isDown(key.DOWN)) {
	if (_root.block.hitTest(this._x, (this._y+speed), false) != "true") {
		this._y += speed;
	}
}

```

The object will still move but will pass through the block(s).

[http://flub.ath.cx/~delirium/test.fla](http://flub.ath.cx/~delirium/test.fla) is where the full code is. Any help would be much appreciated!
