Half-Life Alyx – NPC Console Commands

List of console commands for spawning NPCs.

List of NPC Classes

First I’ll just list all the the NPC classes that at least more or less work.

Fully Working NPCs

• npc_zombie
• npc_zombie_blind
• npc_headcrab
• npc_headcrab_armored
• npc_headcrab_black
• npc_headcrab_runner
• npc_antlion
• npc_barnacle (spawns on the floor, use the give command to spawn it in the air)
• npc_combine_s
• npc_manhack
• npc_crow
• npc_seagull
• npc_pigeon

Somewhat Working NPCs

These ones work fine, they just don’t have a model.

• npc_rollermine
• npc_cscanner
• npc_clawscanner
• npc_combinegunship
• npc_combinedropship
• npc_strider
• npc_sniper

Almost Working NPCs

npc_metropolice (I gave it a model by moving the metrocop_choreo.vmdl model to where it wanted it to be and changed its name, it actually moves around and tries to shoot you, but it can’t.

Keyvalues

I’m pretty sure that’s what they’re called?

These are the things in the curly brackets, like the “additionalequipment weapon_ar2” in

ent_create npc_combine_s {additionalequipment weapon_ar2}

There’s quite a few of these, so I’ll split them up into NPC classes.

every npc

• model [target_destination] Sets the model the NPC will use
• targetname [string] Sets the NPC’s name
• squadname [string] Sets the NPC’s squad

npc_zombie

• model_state [modelstatechoices] This would probably change the zombie type bodygroup, but I’m not sure how it works
• sprint_proclivity [float] Increases the base chance to Sprint and duration of Sprints, while decreasing the cooldown between Sprints. Set to 1 to leave it as is. 0 to never Sprint.
• flinch_chance [float] Multiplies the base chance to play Interrupt Flinches. Set to 1 to leave it as is. 0 to never Interrupt Flinch.
• revivable [boolean] This zombie can be revived by runner headcrabs
• waitforrevival [boolean] This zombie will spawn as a corpse and do nothing while it waits for a revival.
• reviver_group [string] If set, this zombie will only be revived by Runner HCs with a matching reviver group.
• bloater_position [choices] Position of the xen bloater on this zombie, if any.
  -1 : No Bloater, 0 : Chest, 2 : Left Arm, 3 : Right Arm, 4 : Left Leg, 5 : Right Leg
• turret_position [choices] Position of the xen turret on this zombie, if any.
  0 : No Turret, 1 : Left Shoulder, 2 : Right Shoulder
• held_object [target_destination] If set to the name of a prop_physics entity, the Zombie will start holding it, and then throw it at the first enemy encountered.

npc_headcrab

• spawnflags [65536; 131072] 65536 – Start hidden; 131072 – Start hanging from ceiling
• startburrowed [boolean] Start burrowed

npc_headcrab_runner

• reviver_group [string] If set, this Runner will only attempt to revive zombies with a matching reviver group.

npc_combine_s

• use_VRstealth_outside_combat [boolean] Support VR player peeking before I’ve ever been in combat.
• grenade_proclivity [float] Multiplier on the chance to throw grenades, and delay between grenade throws. Set to 1 to leave as default. 0.5 would mean you have twice the chance to throw grenades, and you wait half as long as normal between throws (assuming you have a valid throw)
• manhack_proclivity [float] Multiplier on the chance to deploy manhacks, and delay between manhack deployments. Set to 1 to leave as default. 0.5 would mean you have twice the chance to deploy manhacks, and you wait half as long as normal between deployments (assuming you have a valid deployment)
