Npc metropolice

Entity Description

This NPC is a Combine Civil Protection officer, an enemy from Half-Life 2. They are usually seen suppressing civilians, and will attack the player on sight. They can carry up to two deployable manhacks on their shoulder(s).

Their ai focuses on slowly advancing on an enemy and overwhelming them with numbers. They'll rarely take cover unless on low health or damaged repeatedly.

If a metrocop is armed with an SMG and the player is in the airboat, he can "stitch" by shooting a meandering, closing path of bullets into the water in front of the vehicle.

Note:Some keyvalues, spawnflags, effect flags, inputs, or outputs might not affect an NPC, based on the functionality and coding of the NPC.

RappelNPC:

Waiting to Rappel? (waitingtorappel) <boolean>

If yes, this NPC spawns suspended in air and awaits a BeginRappel input. It will then spawn a zipline and slide down. When it hits the ground, NPC will cut away the line and try to move forward a few feet to make room for the next NPC. The NPC will not attempt to clear its landing space if it cannot do so by taking a few steps forward.

Weapons ([todo internal name (i)]) <choices>

What weapon this Metrocop should spawn with. Choices are:

• Pistol
  Tip:Cops have bad aim with the pistol, so they will periodically take a couple steps toward the player if they can path to him.
• SMG1
• Stun Stick
• Shotgun
  Bug:This NPC doesn't have proper animations for this weapon.  [todo tested in ?]
• Nothing

Number of Manhacks ([todo internal name (i)]) <choices>

Each Metrocop can carry and deploy up to two npc_manhacks.

Pistol starts drawn ([todo internal name (i)]) <boolean>

If the Metrocop's weapon is the Pistol, it will start in its hands. If set to no, the pistol is holstered. No effects with other weapons.

Bug:If a cop has his pistol holstered and he is running a script, such as an standoff, he might end up shooting with an invisible gun!  [todo tested in ?]

Fade Corpse : [512]

Think outside PVS : [1024]

Allows this NPC to run its regular AI outside of any player's PVS.

Template NPC : [2048]

Do Alternate collision for this NPC (player avoidance) : [4096]

Don't drop weapons : [8192]

Ignore player push : [16384] (in all games since )

Entity won't give way to player.

• Simple cops: Lowers the cop's health to 26 instead of 40 and uses more dramatic flinch animations for certain hit-boxes. Used in the early canal levels of the game.
• Always stitch: This forces the behavior to occur. If the metrocop is armed with an SMG and the player is beneath them, they will shoot a meandering, closing, path of bullets.
• No chatter: Gags the NPC, additionally preventing some metrocop-specific speech that gagging itself doesn't.
• Arrest enemies: Causes the cop to "arrest" an opponent it hates. Demonstration Video.
• No far stitching: Stops stitching if the player is over 6000 units away. (Is that in inches?)
• Prevent manhack toss: Don't use my manhack. See the EnableManhackToss input.
• Allowed to respond to thrown objects: The officer can chase players who have annoyed them. Does not override the settings of an ai_goal_police.
• Mid-range attacks (halfway between normal + long-range): Change the metrocop's preferred attack distance.
