I won't waste your time since I know this has been beaten to death with posts and tutorials, but for the enemy "line of sight" problem (an AI's ability to tell whether there is an obstacle between itself and you or not) does anyone have a quick link to a post or tutorial, or know what keywords I should search for in the forum? I remember there being a lot of posts in the old forum about this, but I can't seem to find any anymore. Thanks!
