Tokyo Wangan Racing

A Roblox game where you cruise a neon Tokyo expressway at night in cool cars — starting with a real 1993 Mazda RX-7. The driving feel comes first; everything else layers on top of it. See docs/ROADMAP.md for what comes next.

Status: Playable. Spawn → drive → switch cars → respawn, plus the full three-mode Wangan loop. CI green on a self-hosted Gitea runner. Built code-first — nothing to hand-build in Studio.

The Daikoku loop (how you play)

Daikoku Futo PA is the hub, exactly like Tokyo Xtreme Racer. You are never "joining a match" — you park, pick how you want to run, and drive out.

        IN THE PA  ──►  pick a mode  ──►  cross the exit gate  ──►  RUNNING
             ▲                                                        │
             └──────────────── pull back into the PA ─────────────────┘

Mode	日本語	What it is
CRUISE	流し	Free roam. Bank kilometres, meet other drivers. Rivals can pull alongside and challenge you.
DUEL	バトル	Hunt rivals. First to open a ~350-stud gap and hold it for 3s wins. No laps, no checkpoints — who breaks first.
TIME ATTACK	タイムアタック	Solo flying lap with 4 sector splits and a saved personal best. Rivals can't interrupt you.

Cruise and Duel both allow challenges, so a cruise can turn into a battle organically — pull alongside someone and the prompt appears for both of you. Time Attack deliberately opts out so a hot lap is never ruined.

Kilometres, lap times and duel records all persist via ProfileStore.

Prerequisites

Toolchain is managed by Rokit. With Rokit on your PATH:

rokit install     # rojo, wally, selene, stylua at pinned versions
wally install     # restores ProfileStore into ServerPackages/

Tool	Purpose
rojo	Sync/build code ↔ Roblox place
wally	Package manager (ProfileStore)
selene	Static analysis / linter
stylua	Code formatter

Build & run

rojo build --output build.rbxl   # standalone place file to open in Studio
# OR live-sync into an open Studio place (install the Rojo Studio plugin):
rojo serve

In Studio press Play. You spawn on the expressway in your car. Bottom bar: CARS (switch car) and RESPAWN (re-spawn if you flip). The RX-7 only appears for allowlisted accounts.

Quality gates (CI enforces these on every push)

stylua --check src/     # formatting
selene src/             # lint
rojo build --output build.rbxl   # must compile

CI runs on a self-hosted Gitea Actions runner on UNRAID-1 (Ubuntu 24.04 job container — rojo's binary needs glibc 2.39). Workflow: .gitea/workflows/ci.yml.

Architecture (server-authoritative)

Clients request, the server decides. The RX-7 allowlist and anti-cheat are server-side.

ReplicatedStorage/Shared     GameConfig, Cars, ProfileTemplate, Remotes
ServerScriptService/Server   init.server + managers (below)
ServerScriptService/ServerPackages  ProfileStore (Wally)
StarterPlayerScripts/Client  init.client (HUD + car picker)

Module	Responsibility
DataManager	Wraps ProfileStore — session locking, reconcile, Studio mock. Remembers your last car.
CarManager	Spawns the equipped car (VehicleSeat-driven placeholder) and enforces the RX-7 allowlist.
MapBuilder	Procedurally builds the expressway, spawn pad, neon pylons, kill walls.
AntiCheat	Movement sanity check (speed/teleport) — a speed bump, not a fortress.

The RX-7 demo-lock: GameConfig.RX7AllowedUserIds holds the owner's + son's Roblox UserIds; only they can select/drive the RX-7 (enforced in CarManager and the EquipCar remote).

Replacing the placeholder RX-7 with the real mesh

One function changes: CarManager.buildCarModel. Full step-by-step in docs/MESH_SWAP.md. Reference photos live on the NAS at unraid-1:/mnt/user/data/yy-roblox-games/0-tokyo-wangan-racing/001-original-images/001-1993-Mazda-RX-7/ (12 files). See PROJECT-BRIEF.md for the full reference-asset inventory.
