hitTestPoint AS3

programming
1

Im trying to use hitTestPoint to detect if a enemy has hit a wall. I have the code working for the player, which is located on the main stage (the player doesn’t move, the map scrolls). The map, with the enemies is located in a MC - mainmap. mainmap contains walls MC and an instance of enemy. I can’t seem to get the code to work for the enemy’s hitTest. Any ideas to where Im going wrong? Maybe this is the wrong method to use.

SWF:

Code on the enemy:

for (var i:int = 0; i < thisParent.walls.numChildren; i++) {
		var obj:MovieClip=thisParent.walls.getChildAt(i) as MovieClip;
		if (obj.hitTestPoint(this.x+35,this.y)) {
			this.x-=enemySpeed;
		}
		if (obj.hitTestPoint(this.x-35,this.y)) {
			this.x+=enemySpeed;
		}
		if (obj.hitTestPoint(this.x,this.y+40)) {
			this.y-=enemySpeed;			}
		if (obj.hitTestPoint(this.x,this.y-40)) {
			this.y+=enemySpeed;
		}
}

Any help would be great!
