You also have to remember that they can see just their hand, or maybe their
whole body, so the UTIL_Trace may show there is an entity between the
players vision and an enemy, because they may only see their rifle sticking
out from behind boxes.

Subject: [hlcoders] Enemies within LOS


> What would be the most efficient way to get all enemies within direct LOS?
> My thoughts as of now:
>
> 1.  Get a list of entities within PVS with UTIL_EntitiesInPVS()
> 2.  Filter list for hostile player entities.
> 3.  UTIL_Trace[something] to each.  (Which 'something' is best?)
