## Requirements

- CMake >= 3.16, a C++17 compiler (MSVC, or GCC/Clang on Linux)

- Ubuntu: `sudo apt install build-essential cmake git unzip curl`

Eigen and Boost are **downloaded automatically** by
|
||||
`cmake/FetchDependenciesServer.cmake` into `thirdparty/` the first time CMake
|
||||
configures the project (Boost zip is ~200 MB). A system Eigen3 is used if
|
||||
installed; Boost is always taken from `thirdparty/boost_1_90_0` so versions match
|
||||
the Windows build. Nothing else (SDL, zlib, libzip, ...) is needed.

Linux (recommended helper, 1 compile job to stay within low RAM):

After every build the repository's `resources/` directory is copied next to the
|
||||
binary (`server/build/resources`, or `server/build/Release/resources` on
|

Windows). Content paths are resolved from the process working directory, so the

server must be started from the directory that contains `resources/`.

cmake --build server/build --target GameServer --parallel
|
||||
ctest --test-dir server/build --output-on-failure
|
||||
```
|
||||
|
||||
This does `cd server/build` and runs
|
||||
Eigen3 must either be installed or be available at
|
||||
`thirdparty/eigen-5.0.0`. The headless target reads ordinary filesystem resources
|
||||
only; ZIP-backed campaign loading belongs to the later content-loading
|
||||
milestone.
|
||||
|
||||
Run until interrupted:
|
||||
|
||||
```bash
|
||||
./GameServer --campaign battle_zone_multiplayer --address 127.0.0.1 --port 8081
|
||||
./server/build/GameServer
|
||||
```
|
||||
|
||||
Environment overrides: `CAMPAIGN`, `LOCATION`, `ADDRESS`, `PORT`, `BUILD_DIR`.
|
||||
For a multi-configuration Windows build, the executable is normally
|
||||
`server/build/Release/GameServer.exe`.
|
||||
|
||||
Windows equivalent:
|
||||
For smoke tests, `--ticks N` limits execution and `--no-sleep` skips the
|
||||
real-time delay.
|
||||
|
||||
Start the multiplayer lockstep server:
|
||||
|
||||
```powershell
|
||||
.\server\build\Release\GameServer.exe --campaign battle_zone_multiplayer
|
||||
.\server\build\Release\GameServer.exe --campaign battle_zone_multiplayer --location uni_exterior
|
||||
```
|
||||
|
||||
Command line options: `--campaign ID`, `--location ID`, `--campaigns PATH`
|
||||
(default `resources/config/campaigns.json`), `--address IP` (default `0.0.0.0`),
|
||||
`--port N` (default `8080`), `--ticks N` and `--no-sleep` (smoke tests).
|
||||
The listener defaults to `ws://0.0.0.0:8080`. Launch the Windows graphical game
|
||||
afterward and select `battle_zone_multiplayer`; that campaign connects to
|
||||
`ws://127.0.0.1:8080`. Other campaigns continue to use the in-process server.
|
||||
|
||||
The server sends one state snapshot when a player connects, then broadcasts one
|
||||
numbered command bundle every 100 ms. Bundles may be empty. Destination input is
|
||||
scheduled two ticks (200 ms) in the future. Tick IDs, rather than server or
|
||||
client wall-clock values, define simulation time.
|
||||
|
||||
## Production deployment (Ubuntu, systemd + nginx)
|
||||
If `--location` is omitted, the campaign's configured start location is used.
|
||||
`--campaigns PATH` selects a different campaign registry. Content paths are
|
||||
resolved from the process working directory, so run from the repository root
|
||||
when using the bundled `resources/` tree.
|
||||
|
||||
The server listens on loopback only (`127.0.0.1:8081`); nginx terminates TLS and
|
||||
proxies WebSocket traffic.
|
||||
Available startup options:
|
||||
|
||||
### 1. systemd service
|
||||
|
||||
```bash
|
||||
sudo cp server/deploy/shadow-gameserver.service /etc/systemd/system/
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl enable --now shadow-gameserver
|
||||
systemctl status shadow-gameserver
|
||||
journalctl -u shadow-gameserver -f # logs
|
||||
```text
|
||||
--campaign ID
|
||||
--location ID
|
||||
--campaigns PATH
|
||||
--address IP
|
||||
--port N
|
||||
--tick-ms 100
|
||||
--ticks N
|
||||
--no-sleep
|
||||
```
|
||||
|
||||
The unit caps memory at 512 MB and restarts on failure. After rebuilding run
|
||||
`sudo systemctl restart shadow-gameserver`. Edit `User=`/paths in the unit if the
|
||||
repository lives elsewhere. To run a second server, copy the unit with another
|
||||
`PORT` (and campaign) and add a matching `/server002/` location.
|
||||
Network mode requires a 100 ms tick; another `--tick-ms` value is rejected.
|
||||
The selected campaign's `networkPlayerSlots` lists pre-existing character IDs
|
||||
assigned to connections in order. `networkCompatibility` is a release token
|
||||
that must be changed whenever deterministic content changes; clients reject a
|
||||
different token. The bundled multiplayer Battle Zone has two slots (`player`
|
||||
and `player2`) and rejects additional clients. Disconnecting
|
||||
releases the slot. The bot's random autonomous controller is disabled in
|
||||
multiplayer.
|
||||
|
||||
### 2. nginx
|
||||
The graphical client executes presentation behavior after building its runtime
|
||||
`Location`; the headless content pass loads authoritative navigation, NPC,
|
||||
interactive-object, trigger, teleport, taxi, and animation metadata. Lua and
|
||||
dialogue-driven shared multiplayer behavior is not yet supported.
|
||||
|
||||
```bash
|
||||
sudo cp server/deploy/nginx-api.shadowoverbishkek.com.conf \
|
||||
/etc/nginx/sites-available/api.shadowoverbishkek.com
|
||||
sudo ln -s /etc/nginx/sites-available/api.shadowoverbishkek.com \
|
||||
/etc/nginx/sites-enabled/
|
||||
sudo nginx -t && sudo systemctl reload nginx
|
||||
```
|
||||
## Tests
|
||||
|
||||
`location /server001/` proxies to `http://127.0.0.1:8081/` with WebSocket
|
||||
upgrade headers and a 1 hour read/send timeout (the trailing slashes strip the
|
||||
`/server001` prefix).
|
||||
CTest covers:
|
||||
|
||||
### 3. HTTPS certificate
|
||||
- repeated `LocationGameState::setup()` preserving mutable runtime state;
|
||||
- ticking a prepared location with zero players;
|
||||
- deterministic fixed-100 ms replay behavior;
|
||||
- protocol-v2 parsing, validation, target normalization, state hashing, and
|
||||
two-tick command ordering;
|
||||
- a WebSocket initial-state/slot/destination/tick integration test;
|
||||
- idle server startup;
|
||||
- headless loading of `battle_zone_multiplayer/uni_exterior`.
|
||||
|
||||
DNS for `api.shadowoverbishkek.com` must point at the VDS first.
|
||||
|
||||
```bash
|
||||
sudo certbot --nginx -d api.shadowoverbishkek.com
|
||||
```
|
||||
|
||||
Certbot issues a Let's Encrypt certificate, adds the `443 ssl` block and an HTTP
|
||||
to HTTPS redirect, and installs auto-renewal (`systemctl list-timers | grep certbot`).
|
||||
|
||||
## Connecting
|
||||
|
||||
Public endpoint: **`wss://api.shadowoverbishkek.com/server001/`**
|
||||
|
||||
Handshake check from any machine (expects `HTTP/1.1 101 Switching Protocols`):
|
||||
|
||||
```bash
|
||||
curl -i -N --max-time 3 \
|
||||
-H "Connection: Upgrade" -H "Upgrade: websocket" \
|
||||
-H "Sec-WebSocket-Version: 13" -H "Sec-WebSocket-Key: x3JJHMbDL1EzLkh9GBhXDw==" \
|
||||
https://api.shadowoverbishkek.com/server001/
|
||||
```
|
||||
|
||||
Or interactively: `npx wscat -c wss://api.shadowoverbishkek.com/server001/`.
|
||||
|
||||
Locally on the VDS, bypassing nginx: `ws://127.0.0.1:8081`.
|
||||
|
||||
> **Client limitation:** `src/game_server/WebsocketGameClient.cpp` currently
|
||||
> speaks plain `ws://host:port` to `/` (no TLS, no path). Until TLS and path
|
||||
> support are added to the client, the graphical game can only connect directly
|
||||
> to a non-proxied server (e.g. `ws://127.0.0.1:8080`), not to the `wss://` URL.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
- `Animation metadata failed ... Invalid animation file`: the `.anim` files are
|
||||
Git LFS pointer stubs (`version https://git-lfs...`). Fetch the real files with
|
||||
`git lfs pull` (or copy `resources/` from a full checkout) and rebuild.
|
||||
- `GameServer.LocationState` test currently fails on every platform: it expects
|
||||
`battle_zone` and `battle_zone_multiplayer` to share a start-state file, but
|
||||
`campaigns.json` points them to different files.
|
||||
|
||||
- `Server content setup failed`: the server was not started from the directory
|
||||
containing `resources/` (use `run-server.sh`).
|
||||
- `WebSocket listener setup failed`: port already in use (`ss -ltnp | grep 8081`).
|
||||
- `502 Bad Gateway` from nginx: service not running (`systemctl status
|
||||
shadow-gameserver`).
|
||||
- Connection drops after ~60 s: check `proxy_read_timeout` in the nginx location.
|
||||
- Compiler "Killed" / `internal compiler error`: out of memory, see the memory note.
|
||||
The lockstep implementation currently targets identical executable and content
|
||||
builds. Diagnostic state hashes detect divergence, but there is no automatic
|
||||
checkpoint resynchronization or reconnect input history yet.
