Entity Description
Story-wise, these NPCs are officially known as "Civil Protection" and are the Combine's thought police and the primary police force seen throughout City 17 and its surrounding areas. They beat citizens in the beginning of Half-Life 2 and get beaten by citizens at the end of Half-Life 2. npc_metropolice is much weaker than npc_combine_s in strength, arsenal, and tactics, but its animations are (fittingly) much more natural and help to establish an effective authoritative atmosphere under the right circumstances.

Other than this, however, tactics are mostly limited to taking cover to reload and retreating when taking enough damage. This can change drastically with the help of external elements like ai_goal_standoff or ai_goal_assault, both of which npc_metropolice has unique lines for, or scripted events.
If a npc_metropolice is armed with an SMG and the player is in the airboat, the cop can "stitch" by shooting a meandering, closing path of bullets into the water in front of the vehicle. See the "Always stitch" and "No far stitching" spawnflags for more control over usage and range.

Throughout the chapter Point Insertion of Half-Life 2, npc_metropolice will act very differently. This is due to a global state, gordon_precriminal, that completely changes their attitude towards the player. They will essentially treat them as a regular citizen. (albeit differently from npc_citizen) They will always watch the player when within a certain distance and have unique idle sentences that suggest a calm and secure atmosphere.
They will issue and remember warnings to the player when they do anything to make them angry, ranging from walking into them to hitting them with an empty tin can. They have three warnings, but most agitators go directly to the third warning.
The most common agitator is getting too close to a npc_metropolice. If no warnings have been given, the npc_metropolice will push the player away and give them a warning. If the player has already been warned, the npc_metropolice will threateningly activate their stunstick before pushing them away again and warning them a second time. If the player has been warned three times, they will attack the player with their stunstick from that point forward with no additional consequences of pestering them further. The npc_metropolice will still react differently to the player's presence with the third warning, activating their baton as soon as the player gets within watching distance.
Another agitator is throwing a physics object at the npc_metropolice. This will instantly set the warnings to 3 and cause them to chase the player for 3-7 seconds. If they cannot respond to this (in a script or lacks the "Allowed to respond to thrown objects" spawnflag), the nearest npc_metropolice allowed to respond will chase the player instead.
The only other agitator is pressing +USE on them, which simply adds a warning to the number of warnings or, if the player has already been given 3 warnings, causes them or a nearby npc_metropolice to chase the player.
This behavior is almost completely absent if the npc_metropolice is wielding anything other than a weapon_stunstick. Their behavior will only consist of pushing.
Todo: Test non-stunstick-wielding pre-criminal cops that are allowed to respond to thrown physics objects
All of this behavior is changed drastically with the use of ai_goal_police.
Note:Some keyvalues, spawnflags, effect flags, inputs, or outputs might not affect an NPC, based on the functionality and coding of the NPC.Dedicated Console Variables
- sk_metropolice_health <int>
- A metrocop's spawn health.
- sk_metropolice_stitch_reaction <int>
- How close to the airboat should Metrocops begin stitching.
- sk_metropolice_stitch_at_hitcount <int>
- Number of times a stitching Metrocop can hit a nearby player.
- sk_metropolice_stitch_behind_hitcount <int>
- Number of times a stitching Metrocop can hit a player looking at it.
- sk_metropolice_stitch_tight_hitcount <int>
- Number of times a stitching Metrocop can hit a player from behind.
- sk_metropolice_stitch_along_hitcount <int>
- Number of times a stitching Metrocop can hit a player looking left/right.
Keyvalues
|
CBaseCombatCharacter:
CAI_BaseNPC:
DamageFilter:
|
RappelNPC:
- Waiting to Rappel? (waitingtorappel) <boolean>
- If yes, this NPC spawns suspended in air and awaits a
BeginRappelinput. 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
- Pistol
- 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>
- Whether or not the NPC's pistol should start holstered. The pistol cannot be unholstered with the UnholsterWeapon input and can only be unholstered when the NPC spots an enemy. Has no effect on other weapons.Note:When an officer's pistol starts undrawn, it actually starts invisible and becomes visible after they play the unholoster animation. They will still use pistol animations and they are susceptible to the bug below.
Flags
BaseNPC flags
- Wait Till Seen : [1]
- Prevents this NPC from seeing (or being seen) until it enters a player's viewcone.
- Gag : [2]
- Won't make IDLE sounds until it's angry.
- Fall to ground (unchecked means teleport to ground) : [4]
- Drop Healthkit : [8]
- Causes this NPC to drop an item_healthvial upon dying.
- Efficient : [16]
- Don't acquire enemies or avoid obstacles
- Wait For Script : [128]
- Forces this NPC to "wait" in an idle state until it finishes playing a scripted_sequence.
- Long Visibility/Shoot : [256]
- By default, increases a NPC's sight range to
6,000units and allows it to attack from anywhere within that distance.
- Fade Corpse : [512]
- Think outside PVS : [1024]
- Allows this NPC to run its regular AI outside of any player's PVS.
- Template NPC : [2048]
- Marks this NPC as a template for entities like npc_template_maker. The NPC will not spawn on its own. This is not needed for point_template.
- Do Alternate collision for this NPC (player avoidance) : [4096]Note:This flag is disabled in
episodic for player companions, because the StartScriptinginput does this.
- Don't drop weapons : [8192]
- Ignore player push : [16384] (in all games since
) - Entity won't give way to player.
- 131072 : Simple cops : Lowers the NPC'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.
- 524288 : Always stitch : This forces the stitching 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.
- 1048576 : No chatter : Automatically gags the NPC and supposedly prevents some metrocop-specific speech that standard gagging doesn't. This is now believed to be non-functional.
- 2097152 : Arrest enemies : Causes the cop to "arrest" its opponents. Demonstration Video
- 4194304 : No far stitching : Stops stitching if the player is over 6000 units away.
- 8388608 : Prevent manhack toss : Prevents the cop from deploying their manhack(s). See the EnableManhackToss input.
- 16777216 : Allowed to respond to thrown objects : Only useful in pre-criminal mode. Allows the officer to chase players who have annoyed them. This does not override the settings of an
ai_goal_police. - 33554432 : Mid-range attacks (halfway between normal + long-range) : Extends the metrocop's preferred attack distance to 3500 units.
