Stats List

AI Traits

These values control how actors behave. The base values for these are entered for each NPC or creature in the AI Window in the GECK.

Primary Statistics

S.P.E.C.I.A.L. is the fundamental character system of Fallout. The base values are entered for each NPC or creature in the AI tab in the GECK. These values range from 0 to 10.

Strength - Affects CarryWeight, Unarmed, MeleeWeapons, and MeleeDamage
Perception - Affects Medicine, Lockpick and Explosives
Endurance - Affects Health, HealingRate, PoisonResistance and RadiationResistance
Charisma - Affects Barter and Speech
Intelligence - Affects Science, Repair, Medicine and Explosives
Agility - Affects ActionPoints, SmallGuns, BigGuns, EnergyWeapons, Throwing, Sneak, Unarmed, MeleeWeapons, Lockpick and Explosives
Luck - Affects CriticalChance

Derived Statistics

These actor values are derived based on other statistics, and that derivation becomes the base value. Some can also be entered in to the GECK for an individual NPC or creature. In these cases, the value entered into the GECK is added to a derived value to determine the base value. Remember that calling SetActorValue on an actor value that does not have an entry field in the GECK will have no effect.

CritChance - 99-100, treated as a percentage

DamageResist - 99-100, treated as a percentage
PoisonResist - 99-100, treated as a percentage
RadResist - 99-100, treated as a percentage
SpeedMult - Value is divided by 100. For NPCs, modifies the base speed fMoveBaseSpeed before accounting for encumberance; for creatures this modifies the speed of the animation.

Miscellaneous

Additional actor values.

InventoryWeight - How much the actor is carrying. If InventoryWeight > CarryWeight, the actor is over-encumbered.
Paralysis - If nonzero, the actor is paralyzed
Invisibility - If nonzero, the actor is completely invisible
Chameleon - 0-100, percentage of invisibility
NightEye
DetectLifeRange
FireResist - 0-100, treated as a percentage
WaterBreathing - If nonzero, the actor can breath underwater
RadiationRads - Accumulated radiation, different levels have different effects

Variable01 through Variable10 - no game function, available as a hook for package conditions and scripts
- CAUTION: Be careful when modifying Variable actor values. Due to their non-specific nature, several scripts and package conditions may all be checking these values for widely diverse reasons.
- See User Defined Actor Values for notes on the game's use of these Actor Values (and how to use them anyway).
