Try this:

```php
 
onClipEvent (load) {
s = 5;
b = this.getBounds(this);
function move(x, y) {
if (!_root.limits.hitTest(_x+x+b.xmin+5, _y+y+b.ymin+5, true)) {
if (!_root.limits.hitTest(_x+x+b.xmax-5, _y+y+b.ymin+5, true)) {
	if (!_root.limits.hitTest(_x+x+b.xmin+5, _y+y+b.ymax-5, true)) {
	 if (!_root.limits.hitTest(_x+x+b.xmax-5, _y+y+b.ymax-5, true)) {
	 _x += x;
	 _y += y;
	 }
	}
}
}
}
}
onClipEvent (enterFrame) { 
if (Key.isDown(Key.UP)) {
move(0, -s);
}
if (Key.isDown(Key.DOWN)) {
move(0, s);
}
if (Key.isDown(Key.RIGHT)) {
move(s, 0);
}
if (Key.isDown(Key.LEFT)) {
move(-s, 0);
}
}

```

Hope that helps. Its not mine, but it was taught to me 😃

P.S. its for da walls. I dont know how to make a hitTest for ALL the mcs.
