Raw Blame History

//========= Copyright Valve Corporation, All rights reserved. ============//
//
// Purpose: Security cameras will track a default target (if they have one)
// until they either acquire an enemy to track or are told to track
// an entity via an input. If they lose their target they will
// revert to tracking their default target. They acquire enemies
// using the relationship table just like any other NPC.
//
// Cameras have two zones of awareness, an inner zone formed by the
// intersection of an inner FOV and an inner radius. The camera is
// fully aware of entities in the inner zone and will acquire enemies
// seen there.
//
// The outer zone of awareness is formed by the intersection of an
// outer FOV and an outer radius. The camera is only vaguely aware
// of entities in the outer zone and will flash amber when enemies
// are there, but will otherwise ignore them.
//
// They can be made angry via an input, at which time they sound an
// alarm and snap a few pictures of whatever they are tracking. They
// can also be set to become angry anytime they acquire an enemy.
