SetNet.Locomotion

One unified server-side tick that moves everything — players, mobs, NPCs, projectiles — and replicates nothing.

Create a Mover and it's automatically part of the tick; the system advances its position along a pathfound route N times per second. It sends nothing over the network — you read positions and replicate them your own way. When a mover gets a new destination it fires Started, so you can send just the destination point to clients (L2-style; the client re-paths locally — see SetNet.Locomotion.Unity).

Server

IGeoData geo = GeoDataFile.LoadFromFile("world.geo");
var loco = server.UseLocomotion(geo, new LocomotionOptions { Hz = 10 });   // one unified system

// send just the destination to nearby clients when something starts moving (client re-paths from the point):
loco.Started += m => SendMoveTo(m.Owner, m.Destination!.Value);

// anything that moves creates a Mover — that's the whole subscription:
var mover = loco.CreateMover(spawnPos, speed: stats.Get("move_speed"), owner: character);

// on a client move command / mob AI decision:
mover.GoTo(destination);      // paths there, starts following (false if unreachable)

// the system advances mover.Position every tick — read it for range/AoI or to write into your replicated state:
mover.DestinationReached += m => { /* arrived */ };
mover.Dispose();              // auto-unsubscribe when the entity leaves

What it is (and isn't)

• It simulates, it doesn't replicate. No packets, no StateSync writes — just positions advancing. You decide how the position reaches clients (a NetworkVariable field, an L2 "move to point" event on Started, whatever).
• Automatic subscription. CreateMover registers it; Dispose() removes it. No manual Register.
• Unified. Players, NPCs, projectiles — anything holding a Mover shares the one tick. (Mobs has its own tick; point its movement here too if you want a single system.)
• One reused pathfinder (Pathfinding.For(geo), pooled) for every mover.

API

server.UseLocomotion(geo, options?) (or new LocomotionSystem(geo, options?)) → LocomotionSystem:

• CreateMover(start, speed, owner?) → Mover (auto-subscribed), Movers, Count.
• Update(dtMs) when UseInternalTimer = false (drive it from your own loop).
• Started event — a mover got a new destination (send the point to clients here).

Mover: Position, Speed, Owner, Destination, IsMoving, GoTo(point), Stop(), Warp(point), DestinationReached, Dispose().

Notes

• Server-authoritative — GoTo paths on the server; an unreachable point does nothing.
• L2-style pairing: replicate only the destination on Started; the client runs its own FindPath and walks the model with the Unity NavAgent. Between destinations the server sends nothing.
• Uses SetNet.GeoData.Vec3.
