"Line of sight" problem

[alxmrg37]

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!

I have seen people shoot out a sight bullet to see if anything was between the enemy and the player.

Daily Click might have some article posted about different ways to do this.

Thanks- yeah, I think I know how to do that, but I remember someone made a tutorial a long time ago that used some "look at" function- perhaps it was an extension (my memory of it is pretty hazy.) The sight bullet should work though, thanks.

There's a very good line of sight system by LAJ <here>.

I wish someone would integrate this into an extension (e.g. advanced direction object, which is needed for it anyway), in a real easy way of use - like a condition (which is of course negatable):
[events]
* [obj_ado] Obstacle in line (X1, Y1, X2, Y2)
[/events]

Does anyone know who's in charge of the advanced direction object these days?

There isn't much (one tutorial link) on the wiki about line of sight. So if you guys find anything please add it there.
