pyOpenTTDAdmin

pyOpenTTDAdmin is a Python library designed to facilitate communication with OpenTTD's Admin port. OpenTTD (Open Transport Tycoon Deluxe) is an open-source simulation game where players manage a transport company.

This library enables developers to interact with an OpenTTD server programmatically, allowing them to perform various administrative tasks and receive real-time updates from the game server.

Features

• Authentication: Authenticate with an OpenTTD server using the provided password.
• Packet Handling: Receive and parse packets from the server, allowing developers to react to different events and messages.
• Sending Commands: Send commands to the OpenTTD server, such as chat messages, remote console commands, and more.
• Subscription to Updates: Subscribe to various types of updates from the server, including chat messages, client information, company data, and more.
• Flexible Usage: The library provides a flexible framework for building custom applications that interact with OpenTTD servers.

Usage

The basic usage of pyOpenTTDAdmin involves creating an instance of the Admin class, subscribing to updates from the server, and handling the received packets.

Example code for an echo bot can be found here:

from pyopenttdadmin import Admin, AdminUpdateType, openttdpacket

# Set the IP address and port number for connection
ip_address = "127.0.0.1"
port_number = 3977

# Instantiate the Admin class and establish connection to the server
admin = Admin(ip = ip_address, port = port_number)
admin.login("pyOpenTTDAdmin", password = "toor") # assuming the password is "toor"

# Subscribe to receive chat updates
admin.subscribe(AdminUpdateType.CHAT)

# Print chat packets
@admin.add_handler(openttdpacket.ChatPacket)
def chat_packet(admin: Admin, packet: openttdpacket.ChatPacket):
    print(f'ID: {packet.id} Message: {packet.message}')

# Echo chat
@admin.add_handler(openttdpacket.ChatPacket)
def echo_chat(admin: Admin, packet: openttdpacket.ChatPacket):
    admin.send_global(packet.message)

# Run admin
admin.run()

pyOpenTTDAdmin also support async/await syntax:

import asyncio
from aiopyopenttdadmin import Admin, AdminUpdateType, openttdpacket

# Set the IP address and port number for connection
ip_address = "127.0.0.1"
port_number = 3977

async def main():
    # Instantiate the Admin class and establish connection to the server
    admin = Admin(ip = ip_address, port = port_number)
    await admin.login("pyOpenTTDAdmin", password = "toor") # assuming the password is "toor"

    # Subscribe to receive chat updates
    await admin.subscribe(AdminUpdateType.CHAT)

    # Print chat packets
    @admin.add_handler(openttdpacket.ChatPacket)
    async def chat_packet(admin: Admin, packet: openttdpacket.ChatPacket):
        print(f'ID: {packet.id} Message: {packet.message}')

    # Echo chat
    @admin.add_handler(openttdpacket.ChatPacket)
    async def echo_chat(admin: Admin, packet: openttdpacket.ChatPacket):
        await admin.send_global(packet.message)

    # Run admin
    print("running")
    await admin.run()


if __name__ == "__main__":
    asyncio.run(main())

Available Subscribe Types and Packet Types

The following are the available subscribe types that can be used with the library:

• DATE: Updates about the date of the game.
• CLIENT_INFO: Updates about the information of clients.
• COMPANY_INFO: Updates about the generic information of companies.
• COMPANY_ECONOMY: Updates about the economy of companies.
• COMPANY_STATS: Updates about the statistics of companies.
• CHAT: The admin would like to have chat messages.
