Note:In the Nexus building (the d3_c17_10b map) these were seen entrenched within the floor, and could only be killed by blast damage, like lobbing a hand grenade inside its lift. That lift, and the ability to destroy the turret, is not part of this entity. (The lift was a func_door brush rig, and the player really killed an invisible npc_bullseye, filtered to be killed by blast damage only by a filter_damage_type, that signalled the turret to descend and lock.
Note:This entity may be neutral to the player by default! In such cases, an ai_relationship will be required.
Important:This entity operates in a very particular way. On spawn, it remembers its origin position as the "closed" position. It considers itself "closed" unless its Z coordinate is more than 1 unit away from that remembered position. If it is "closed", it will not produce the scanning beam effect and sounds (but will still attack things it hates).
As such, to make it work the same way as in Half-Life 2, it must be parented to another entity that can move up and down, and thus be moved up or down for more than 1 unit of distance. Once it moves, it'll start scanning. The Enable input will then make the turret fully active.
Bug:Rotating the turret after it activated causes the laser effect to dislocate from the gun.
Note:Some keyvalues, spawnflags, effect flags, inputs, or outputs might not affect an NPC, based on the functionality and coding of the NPC.
