# Red Planet 4.12 — the Steamification

**Red Planet** is VWE's pod-racing game: eight-player VTV contests on Mars
— **Martian Death Race** and **Martian Football** — originally played from
inside VWE Tesla cockpit pods. This repo is the third life of that code:

| Generation | What it was |
|------------|-------------|
| **Red Planet 4.10** | The original game, running on the **Tesla 1** pod platform (DOS-era MUNGA engine, serial RIO cockpit hardware, operator console, batch-file relaunch between missions) |
| **Red Planet 4.11** | The **Win32 port** of 4.10 ([RP411](https://gitea.mysticmachines.com/VWE/RP411.git)) — DirectX 9, WinSock TCP, TeslaConsole/TeslaLauncher session control; still runs in pods, still a LAN |
| **Red Planet 4.12** | **This repo: the Steamification of 4.11** — the same engine, the same wire protocol, the same missions, made distributable on Steam and playable over the internet with no cockpit hardware |

The architecture is deliberately conservative: the VWE's design survives
intact, with each pod-era dependency replaced by a consumer equivalent
behind the engine's existing seams.

| Arcade (4.10/4.11) | 4.12 replacement |
|--------------------|------------------|
| RIO cockpit board (serial) | **PadRIO** — virtual RIO from XInput pad + keyboard, fully rebindable (`bindings.txt`, vRIO profile format) |
| Seven physical displays | **Single-window cockpit** — all displays composed on a locked 1920×1080 canvas around the viewscreen, with the real button banks lamp-lit and clickable |
| Pod button lamps | On-screen lamps, plus an **RGB keyboard mirror** (Windows Dynamic Lighting) |
| TeslaConsole operator | **In-game front end** — race setup menu builds the mission egg locally; an in-process console marshals every race (missions still only end on a console stop, exactly as designed in 1994) |
| TeslaLauncher relaunch-per-mission | **Single binary** — menu → race → results → menu in one process |
| WinSock TCP LAN mesh | **NetTransport seam** — the deterministic pod mesh unchanged, running over plain TCP (LAN/dev) or **Steam Networking Sockets** (FakeIP + Steam Datagram Relay) |
| Site network / fixed IPs | **Steam lobbies** — lobby owner is the console; members exchange FakeIPs and loadouts as lobby data |

**Status: it works.**
[v4.12.2](https://gitea.mysticmachines.com/VWE/RP412/releases/tag/v4.12.2)
carried the first verified end-to-end internet build: three machines, three
Steam accounts, lobby → mesh → marshaled five-minute race → deaths and
respawns → timed stop → results on every machine → rematch from the same
lobby.

[v4.12.3](https://gitea.mysticmachines.com/VWE/RP412/releases/tag/v4.12.3)
is about the screen. The cockpit now scales up as well as down and re-fits
whenever the window changes, keeping 16:9 so a wide panel letterboxes
instead of stretching; `-fit` runs it borderless over the whole monitor and
picks the render size to land on the viewscreen 1:1. The displays are the
player's to arrange — each of the six can be scaled on its own and the
radar moved out of the middle of the road (`environ.ini`). Each display's
button bank now reaches under its glass, so the picture itself is the press
target rather than a sliver at the edge.

[v4.12.4](https://gitea.mysticmachines.com/VWE/RP412/releases/tag/v4.12.4)
is about the lobby. Both rooms now show the host's mission setup — the track,
then time of day, weather and game length — since everyone flies the owner's
picks and it was the one thing in the room nobody could see for themselves.
The football team sheet names each player's VTV beside their team colours and
position. And a lobby holds **eight** players rather than four, a full grid as
the pod hall ran it, with the room sizing its roster to whatever space the
window gives it.

[v4.12.5](https://gitea.mysticmachines.com/VWE/RP412/releases/tag/v4.12.5)
restores the **Winners Circle**. The pod hall stood the finishers on a
numbered award platform when the race ended, and all of it was still in this
repo — the stand, eight ranked spots in every map, and the code to put racers
on them — wired only into the mission-review build and so never once run by a
pod. The race now fades out and fades back in on the platform: finishers in
finishing order, each pilot's callsign on the plate beside their spot, the
cockpit glass cleared away, held for a few seconds before the results screen.
Three pieces of it had been stubbed out in the D3D9 port and are working
again.

[v4.12.6](https://gitea.mysticmachines.com/VWE/RP412/releases/tag/v4.12.6)
is about the windows. Where you put them now survives the
menu-race-menu loop: `RP412MFDLAYOUT` remembers the game window, the
exploded view's display panes and the plasma glass in `mfd_layout.cfg`
beside `bindings.txt`. Append `,noframe` to a line to take that
window's title bar and border off — a cockpit filling the monitor edge
to edge at a rect you chose, rather than `-fit` taking the whole
screen — and the setup screen carries its own **EXIT GAME** button,
since a window with no title bar needs a way out. The Steam buttons
now dim and say *STEAM NOT RUNNING* instead of disappearing. And the
Winners Circle camera is framed off the award stand itself rather than
off whoever is standing on it, so the shot is the same one for every
player at every head count.

## Playing

Grab the release zip (or run `pack-dist.ps1` on a build). Single player:
run `start-windowed.bat` — the game boots into the setup menu, where the
SCENARIO group picks Death Race or Football (Football swaps in the
team/position columns and its own track list). Steam multiplayer: see
[docs/STEAM-3-MACHINE-TEST.md](docs/STEAM-3-MACHINE-TEST.md) (until RP412
has its own AppID it runs under Spacewar, 480).

The two config files beside the exe are self-documenting: **environ.ini**
(every engine option, commented) and **bindings.txt** (every key, pad
button, and axis; written with the full default layout on first run).
Default controls: numpad flies (8/2/4/6 stick, 7/9 pedals, 0 trigger),
Shift/Ctrl throttle, Alt reverse, arrows look, Space fires, letter rows
are the MFD button banks as printed on the panel. **Alt+Q** aborts a
mission. Full map with pad and keyboard diagrams:
[docs/CONTROLS.md](docs/CONTROLS.md).

## Building

**VS 2022 (v143)** + DirectX SDK June 2010 + the vendored Steamworks SDK
(`extern/steamworks_sdk_164`) — see [BUILD.md](BUILD.md). Solution
`WinTesla.sln`, configuration `Release|Win32`, output
`Release\rpl4opt.exe`.
