Remarks

Unity's NavMesh crowd is one global simulation. A scene server stacks several instances of the same world scene at the same coordinates, so with obstacle avoidance on, an NPC in one instance steered around NPCs in every other — invisible shoves, tripped stuck timers, spawner-mates in two instances pushing each other off their paths. Avoidance is therefore off on every NPC agent (AIController.InitializeOnce) and this takes its place.

It is scene-scoped by construction: neighbours come from the NPC's own UnityEngine.PhysicsScene, which the scene server gives every stacked instance separately (LocalPhysicsMode.Physics3D). Attackers around one target are spaced by AICombatSlots; this only stops bodies overlapping in the wander, idle and approach cases the ring does not cover.

Methods

Resolve(Vector3, IReadOnlyList<Vector3>, float, float)

The velocity that moves self out of its neighbours' bodies.

public static Vector3 Resolve(Vector3 self, IReadOnlyList<Vector3> neighbours, float radius, float maxSpeed)

Parameters

self Vector3

This NPC's position.

neighbours IReadOnlyList<Vector3>

Positions of nearby NPC bodies.

radius float

Distance at which a neighbour starts to push, in metres.

maxSpeed float

Push speed when fully overlapped, in metres per second.

Returns

Vector3

A horizontal velocity, zero when nothing is inside the radius.
