Spawnarg Explanation

This is a short explanation what the respective spawnarg does. The information is taken from the explanations in the def-files. For clarity the spawargs were divided into three subgroups: Combat related spawnargs that include spawnargs influencing the fighting capabilities; Interactions that cover interactions between the player and the AI as well as the AI and the world; AI perception that include spawnargs that influence how the AI perceive their surroundings; and finally other that in my understanding do not fit the other categories.

Combat related

armor	Type of armor the AI is wearing (may vary depending on hit zone). The damage multipliers are: leather 0.75, chain 0.5, plate 0.
attack_accuracy	Maximum angular offset to randomly offset the monster's aim when firing missiles
attack_cone	Monster can only throw projectile within this cone relative to his direction.
bleed	If set to true, this entity will bleed, e.g. spawn blood particles and decals when hurt.
damage	Damage definition if it damages things it collides with.
health	Amount of damage to receive before dying.
health_critical	When the health drops below this value, the AI will flee. Set this to 0 for AI that don't wet their pants.
melee_damage	Damage dealt with a melee weapon.
melee_damage_mod	When the AI hits with a melee weapon, this multiplies the default damage done by the weapon. Is depending on difficulty and is replaced by melee_sets. Ranges from 0.8 to 1.4.
melee_predicts_proximity	If true, AI takes the current velocity of itself and its enemy into account to predict whether it will hit the enemy in the future if it starts a melee attack now. All but the stupidest AI should do this.
melee_predicted_attack_time	The amount of time in milliseconds that the AI uses to predict whether it will hit its enemy if it starts its attack now. Should roughly correspond to the time it takes before the attack animation is threatening to an enemy in front of them. This baseline can be set on an AI for empty-hand attacks, then may be overwritten by individual weapons if their attack animations are slower/faster than this baseline.
melee_range	do melee attack when within 3x this range
melee_rep_attack_time	Time it takes for a melee attack to be repeated.
outofreach_projectile_delay_max	Maximum period to wait between throwing player-out-of-reach projectiles
outofreach_projectile_delay_min	Minimum period to wait between throwing player-out-of-reach projectiles
outofreach_projectile_enabled	Ability to throw player-out-of-reach projectiles at the player.
pain_threshold	How much damage monster has to receive in one blow for it to play a pain animation.
unarmed_melee	Set this to 1 when this type of AI doesn't need melee weapons to fight. This is usually true for spiders, undead and such. Humans are wimps and need weapons.
unarmed_ranged	Set this to 1 when this type of AI doesn't need weapons for ranged combat. This is usually true for belchers.

Interactions

blind_time	The time span in seconds the AI is staying in 'blinded' state when hit by a flashbomb or -mine.
blind_time_fuzziness	his is the random portion of 'blind_time'. A value in [blind_time-fuzziness ... blind_time+fuzziness] is chosen.
can_be_flatfooted	If set to true, the AI becomes flat-footed in certain combat situations. This means they're unable to run at the player, but can still turn to face the player.
can_drown	If true, the AI will drown if it gets under water, either by walking in or by being dropped in unconsciously. Set to '0' to make them breathe under water.
canlighttorches	AI ability to switch on torches
canoperatedoors	AI ability to handle doors
canoperateelevators	AI ability to handle elevators
canoperateswitchlights	AI ability to operate light switches
cansearch	Whether the AI can conduct a search or not
cansearchcooperatively	ability to participate in a coordinated search
gas_immune	0 = not immune, 1 = immune to gas
ko_alert_immune	If true, the AI is immune to knockouts when alerted at or above the alert state defined in 'ko_alert_state'.
ko_alert_immune_state	Alert state number at which immunity behavior changes.
ko_alert_state	Alert state number at which knockout behavior changes.
ko_angle_alert_horiz	Horizontal knockout cone angle when the AI is alerted at or above 'ko_alert_state'.
ko_angle_alert_vert	Vertical knockout cone angle when the AI is alerted at or above 'ko_alert_state'.
ko_angle_horiz	Defines a horizontal cone angle extending backwards from the direction AI is looking. Anywhere within this cone and the vertical cone is a valid KO.
ko_angle_vert	Defines a vertical cone angle extending backwards from the direction AI is looking. Anywhere within this cone and the horizontal cone is a valid KO.
ko_immune	0 = not immune, 1 = immune to blackjack
ko_rotation	A vector of 3 space-delimited angles applied to rotate the AI's blackjack acceptance cone relative to their head joint. For most heads, the angles are: yaw pitch roll.
ko_spot_offset	Defines the center of the head for knockout testing purposes. Vector offset from the head attachment joint to the desired head center point. The possible knockout cone extends back from this point.
ko_zone	Name of the damage zone that must be hit for a possible knockout. Set this blank (i.e. : 'ko_zone' ) to make the AI immune to KOs from the blackjack.
pickpocket_alert	Incremental alert value to be added to an AI's current alert level
pickpocket_delay_max	Maximum delay before reacting to a picked pocket
picpocket_delay_min	Minimum delay before reacting to a picked pocket
push_player	Set this to 1 to let this entity push the player (default is 0).
sneak_attack_alert_state	Alert state number at which the AI can no longer be sneak attacked.
sneak_attack_mult	Damage multiplier applied to ALL damage when AI is damaged at an alert level below that defined in 'sneak_attack_alert_state'.

AI perception

acuity_aud	AI aural acuity (in percent)
acuity_env	AI environmental acuity. How sensitive the AI is to things that have changed in its environment.
acuity_other	AI generic acuity for scripted events. You can call this alert type on an entity with entity.Alert( <char *type>, <float amount>). This will alert the entity by amount * acuity_other in your script.
acuity_tact	AI tactile acuity (in percent)
acuity_vis	AI visual acuity (in percent)
alert_aud_thresh	Threshold of audibility for the AI. This is in dB of sound pressure level (SPL). The real life value for humans is around 20 (a barely heard whisper). Changing this by even 0.1 has a large effect on sound propagation behavior, because propagated sounds below this volume are not heard at all. NOTE if this is not set, it gets the value from soundprop global settings.
chancenoticeblood	Chance to notice the visual stim of blood
chancenoticebrokenitem	Chance to notice the visual stim of a broken item
chancenoticedoor	Chance to notice the visual stim of an open door that should be closed
chancenoticelight	Chance to notice the visual stim of a light that should be on
chancenoticemissingitem	Chance to notice the visual stim of a missing item
chancenoticemonster	Chance to notice the visual stim of a monster
chancenoticeperson	Chance to notice the visual stim of other persons
chancenoticepickedpocket	Chance to notice that an object bound to the AI has been stolen
chancenoticerope	Chance to notice the visual stim of a rope created by a rope arrow
chancenoticesuspiciousitem	Chance to notice the visual stim of suspicious items
chancenoticeundead	Chance to notice the visual stim on an undead
chancenoticeweapon	Chance to notice the visual stim of suspicious weapons
drunk_acuity_factor	If the AI is drunk, their acuities (visual, hearing, tactile) will be reduced by this factor.
fov	Full field of view in degrees. Will be used for both horizontal and vertical fov unless vertical is explicitly specified.
fov_rotation	A vector of 3 space-delimited angles applied to rotate the AI's field of view relative to their head joint. For most heads, the angles are: yaw pitch roll.
fov_vert	Full vertical field of view in degrees. Leave blank or set to -1 to use the same value as the horizontal fov.
headturn_chance_idle	The chance for random head turning while idle (0.0-1.0)
headturn_factor_alerted	The headturning chance gets multiplied by this amount when the AI is alerted

Other

ignore_alerts	ignores alerts; melee trainer only
is_civilian	If true, the AI is a civilian. Defaults to 0.
is_mantleable	If set to 1, this entity is not mantleable by the player. Defaults to 0.
move_speed	The movement speed of AIs is dependent on their animations and animation rate.
stamina	Determines how long the player can run. I have found this only for the player, not for AI.
team	Monsters do not actively attack players or monsters with the same team number. For common team numbers see AI Relations (Editing).
