Code-only first pass. The local Player.prefab (ball) is still in the scene
until the user creates the PlayerCar / RemoteCar prefab variants in the Editor.
New scripts:
- VehicleLocalSetup: attaches name label + colored capsule marker to the local
vehicle, registers its Rigidbody with NetworkManager for broadcast.
- RemoteVehicleSync: snapshot interpolation for remote vehicles. Disables the
NWH VehicleController + every WheelController + every AudioSource on init.
Makes the rigidbody kinematic, MovePosition-driven from network. Disables all
non-trigger colliders during the 1.5s spawn grace window to avoid ejecting
overlapping locals at connect.
Adapted scripts:
- NetworkManager: RegisterLocalVehicle(Transform, Rigidbody) replaces the
FindFirstObjectByType<PlayerController>() lookup. Remote spawn now wires
RemoteVehicleSync instead of RemotePlayerController.
- LobbyUI: OnConnected drives VehicleLocalSetup.SetupLocal; OnDisconnected
toggles NWH.VehicleController instead of PlayerController.
- GameManager.SetPlayerActive: toggles VehicleController, not PlayerController.
- DebugNetworkUI: live position read from VehicleController.vehicleRigidbody.
- ChatUI: drops PlayerController.ResetInputs() (NWH polls Input System each
frame; no manual reset needed when chat opens).
- StatsTracker: drops dead _pc field; Rigidbody still gets resolved via
GetComponent on the host GameObject (will be the vehicle on Car).
Frontend (deployed earlier on master): build_ball replaces pretty_build assets.
