The Admin Network has no native packet for listing individual vehicles, so list_vehicles() sends a "list_vehicles" command over the existing GameScript JSON channel and relies on a companion server-side script to reply with vehicle data via ServerGamescript. Requires subscribing to Gamescript updates (documented in docs/PROTOCOL.md) to receive the reply. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

# OpenTTD Python Client
|
|
|
|
A high-performance, Object-Oriented Python client for OpenTTD servers, specifically optimized for **JGR Patch Pack (JGRPP)**. This client handles the modern secure handshake, including X25519 PAKE authentication and AEAD stream encryption.
|
|
|
|
## 🚀 Features
|
|
|
|
- **Secure Authentication:** Full implementation of X25519 PAKE (Password-Authenticated Key Exchange).
|
|
- **Stream Encryption:** Automatic XChaCha20-Poly1305 authenticated encryption for all game traffic.
|
|
- **Modular Design:** Separates low-level binary protocol handling from high-level game logic.
|
|
- **State Management:** Handles the full join sequence including Map download and synchronization.
|
|
- **Comprehensive Testing:** Robustly tested with unit, logic, and E2E tests (including 100% coverage for unit/logic tests).
|
|
- **Vehicle Listing:** Query vehicle data via the Admin GameScript channel with `list_vehicles()`.
|
|
|
|
## 🛠 Setup
|
|
|
|
### Prerequisites
|
|
- Python 3.11+
|
|
- A running OpenTTD server (preferably JGRPP)
|
|
|
|
### Installation
|
|
1. Create and activate a virtual environment:
|
|
```bash
|
|
python3 -m venv venv
|
|
source venv/bin/activate # Linux/macOS
|
|
```
|
|
2. Install dependencies:
|
|
```bash
|
|
pip install openttd-protocol pymonocypher
|
|
```
|
|
|
|
## 📖 Usage
|
|
|
|
### Running the default client
|
|
The `main.py` script is configured to join the local server and the company "Én transport".
|
|
|
|
```bash
|
|
python3 main.py [Username] [CompanyID]
|
|
```
|
|
|
|
Example:
|
|
```bash
|
|
python3 main.py MyBot 0
|
|
```
|
|
|
|
### Module Integration
|
|
You can use the `openttd` package in your own projects:
|
|
|
|
```python
|
|
from openttd import OpenTTDClient
|
|
|
|
client = OpenTTDClient(host="127.0.0.1", username="BotName")
|
|
await client.connect(server_password="asd")
|
|
await client.join_company(company_id=0, company_password="asd123")
|
|
|
|
await client.joined.wait()
|
|
# Your logic here...
|
|
```
|
|
|
|
## 📂 Project Structure
|
|
|
|
- `main.py`: Main entry point and usage example.
|
|
- `lib/openttd/`: Core package containing the protocol and client logic.
|
|
- `docs/`: Extensive documentation on architecture, protocol, and contributing.
|
|
- `tests/`: Comprehensive test suite (Logic, Protocol, E2E).
|
|
|
|
## 🧪 Testing
|
|
We maintain high test coverage. To run normal (non-E2E) tests:
|
|
```bash
|
|
pytest -m "not e2e"
|
|
```
|
|
For detailed instructions on E2E testing and coverage reports, see the [Testing Guide](file:///home/kovagoadi/openttd-client/docs/TESTING.md).
