Remarks

Kept separate from AggressionController because these modes deliberately ignore the threat table — a rampaging beast or a critter that just bites whatever is nearest has no interest in who has done the most damage to it.

Methods

GetHealthPercent(ICharacter)

Returns a character's health as a fraction (0-1) of its maximum, or 1 when unknown.

public static float GetHealthPercent(ICharacter character)

Parameters

character ICharacter

The character to measure.

Returns

float

The health fraction.

IsValidTarget(ICharacter)

Returns true when a candidate is a legal target: present, active, and alive.

public static bool IsValidTarget(ICharacter candidate)

Parameters

candidate ICharacter

The candidate to test.

Returns

bool

True if the candidate can be attacked.

PickNearest(List<ICharacter>, Vector3)

Picks the living candidate physically closest to a position.

public static ICharacter PickNearest(List<ICharacter> candidates, Vector3 origin)

Parameters

candidates List<ICharacter>

Candidates to choose from.

origin Vector3

The position to measure from.

Returns

ICharacter

The nearest valid candidate, or null when none are valid.

PickRandom(List<ICharacter>, DeterministicRNG)

Picks a uniformly random living candidate using the NPC's seeded RNG.

public static ICharacter PickRandom(List<ICharacter> candidates, DeterministicRNG rng)

Parameters

candidates List<ICharacter>

Candidates to choose from.

rng DeterministicRNG

The NPC's deterministic RNG. Falls back to the shared RNG when null.

Returns

ICharacter

A random valid candidate, or null when none are valid.

PickWeakest(List<ICharacter>)

Picks the living candidate with the lowest health fraction.

public static ICharacter PickWeakest(List<ICharacter> candidates)

Parameters

candidates List<ICharacter>

Candidates to choose from.

Returns

ICharacter

The most wounded valid candidate, or null when none are valid.
