LimbUtil

LimbUtil

Namespace: ScavLib.util

Safe wrappers around the player's Body.limbs[] array. All methods return safe defaults (null, false, 0) when no world is loaded or the requested limb does not exist — they will never throw a NullReferenceException.

---

LimbSlot Enum

Named indices for the three anatomically fixed limbs. Use these instead of raw integers for self-documenting code.

public enum LimbSlot
{
    Head   = 0,  // Jaw, brain, concussion checks
    Thorax = 1,  // Ribs, breathing, hemothorax
    Pelvis = 2,  // Base posture limb
}

Arms and legs occupy indices 3 and above in Body.limbs[]. Access them by raw index via GetLimb(int) or by name via GetLimbByName(string).

---

Limb Access

GetLimb(int index)

Returns the Limb at the given index, or null if the index is out of range or no world is loaded.

Limb head = LimbUtil.GetLimb(0);

GetLimb(LimbSlot slot)

Named overload for the three fixed limbs.

Limb thorax = LimbUtil.GetLimb(LimbSlot.Thorax);

GetLimbByName(string name)

Find a limb by its GameObject.name. Returns null if not found.

Limb rightArm = LimbUtil.GetLimbByName("RightArm");

GetAllLimbs()

Returns a List<Limb> of all limbs on the player's body. Returns an empty list if not in game.

foreach (var limb in LimbUtil.GetAllLimbs())
    GameUtil.Log($"{limb.name}: skin={limb.skinHealth:F0}");

Aggregate State Queries

These scan all limbs and return a summary result. Useful for condition checks without iterating manually.

Method	Returns	Description
HasBrokenBone()	bool	true if any non-dismembered limb is broken.
HasDislocation()	bool	true if any non-dismembered limb is dislocated.
HasInfection()	bool	true if any non-dismembered limb has an active infection.
HasDismemberment()	bool	true if any limb has been dismembered.
GetMaxInfection()	float	Highest infectionAmount across all non-dismembered limbs. 0 ~ 100.
GetAveragePain()	float	Mirrors Body.averagePain — highest limb pain after Resilience reduction.
GetTotalBleedSpeed()	float	Total bleed speed across all limbs minus blood regen speed.

if (LimbUtil.HasBrokenBone())
    GameUtil.Alert("You have a broken bone.", important: false);

if (LimbUtil.GetMaxInfection() > 50f)
    GameUtil.Alert("Infection is severe!", important: true);

float bleed = LimbUtil.GetTotalBleedSpeed();
if (bleed > PlayerUtil.Thresholds.BLEED_SPEED_HEAVY)
    GameUtil.Alert("Heavy bleeding!", important: true);

Per-Limb Manipulation

HealLimb(Limb limb)

Fully heal a single limb: restores skin and muscle health to 100, clears bleeding, pain, infection, and shrapnel, and calls MendBone() / UnDislocate() if needed. Does nothing if the limb is dismembered.

LimbUtil.HealLimb(LimbUtil.GetLimb(LimbSlot.Head));

HealLimb(int index)

Index overload — equivalent to HealLimb(GetLimb(index)).

LimbUtil.HealLimb(0); // Heal head

DamageSkin(Limb limb, float amount)

Reduce a limb's skinHealth by amount, clamped to 0 ~ 100.

LimbUtil.DamageSkin(LimbUtil.GetLimb(LimbSlot.Thorax), 30f);

DamageMuscle(Limb limb, float amount)

Reduce a limb's muscleHealth by amount, clamped to 0 ~ 100.

Per-Limb Raw Writes

Direct field assignments with clamping. Use when you need precise control over a single limb property.

Method	Range	Description
SetSkinHealthRaw(Limb, float)	0 ~ 100	Set skin health directly.
SetMuscleHealthRaw(Limb, float)	0 ~ 100	Set muscle health directly.
SetBleedRaw(Limb, float)	0 ~ 100	Set bleed amount directly.
SetPainRaw(Limb, float)	0 ~ 100	Set pain directly.
SetInfectionRaw(Limb, float)	0 ~ 100	Set infection amount. Auto-clears infected flag at 0; auto-sets it above 0.

Limb head = LimbUtil.GetLimb(LimbSlot.Head);

LimbUtil.SetSkinHealthRaw(head, 50f);
LimbUtil.SetBleedRaw(head, 0f);
LimbUtil.SetInfectionRaw(head, 0f); // also clears infected flag

        // Check for dangerous conditions
        if (LimbUtil.GetTotalBleedSpeed() > PlayerUtil.Thresholds.BLEED_SPEED_CRITICAL)
            GameUtil.Alert("Critical bleeding!", important: true);

        if (LimbUtil.HasInfection())
            GameUtil.Log($"Max infection: {LimbUtil.GetMaxInfection():F1}");
