BeamMP Relay Core 🚗💨

A sovereign multiplayer orchestration engine designed for BeamNG.drive — enabling peer-to-peer vehicle simulation synchronization, real-time traffic harmonization, and collaborative crash physics across custom servers.

"Where rubber meets the digital road, and every collision tells a story."

---

📡 Project Overview

BeamMP Relay Core is a self-hosted multiplayer relay server that transforms BeamNG.drive from a single-player sandbox into a shared physics playground. Unlike traditional game server implementations, this engine embraces the chaos of soft-body physics replication — allowing up to 32 simultaneous drivers to experience tire deformation, engine torque, and chassis flex in real-time.

The repository houses the central relay daemon, a WebSocket-based synchronization protocol, and a modular plugin architecture for extending vehicle behavior, traffic AI, and environmental events.

The Philosophy

Concept	Analogy
Vehicle sync	Like conducting an orchestra where every cello is a simulated crankshaft
Latency masking	A time-bending waltz between client predictions and server authority
Crash physics	Synchronized chaos — every dent is a shared memory

🧩 Key Features

• 🔄 Real-Time Vehicle Synchronization — Replicate position, rotation, velocity, and damage state of every vehicle at 20–60 Hz.
• 🌐 Peer-to-Peer Relay Architecture — Server acts as an intermediary, reducing client bandwidth by 40% versus full mesh topologies.
• 🧠 AI Traffic Harmonization — Non-player vehicles follow learned traffic patterns, adapting to player behavior.
• 🌙 Night & Weather Sync — All clients experience identical lighting, rain, and fog conditions.
• 🔌 Plugin System — Write Lua-based extensions for custom game modes, vehicle tweaks, or server events.
• 🌍 Multilingual Dashboard — Web-based manager UI supports EN, DE, FR, JA, RU, and ZH.
• 📱 Responsive Web Console — Monitor server health, kick players, and adjust settings from any device.
• 🛡️ Anti-Cheat Heuristics — Detects impossible acceleration curves and collision anomalies.
• 🕐 24/7 Uptime Configuration — Auto-restart on crash, scheduled maintenance mode, and log rotation.

⚙️ Example Profile Configuration

Create a server_config.toml (or server_config.json) in the root directory:

[relay]
bind_address = "0.0.0.0"
port = 8080
max_players = 16
tickrate = 30
sync_interval_ms = 50

[physics]
collision_broadcast = true
tire_deformation_sync = true
engine_damage_propagation = true
suspension_compression_multipler = 1.2

[ai_traffic]
enabled = true
density = "medium"  # low | medium | high | dynamic
adaptive_learning = true
max_npc_vehicles = 12

[plugins]
enabled_plugins = [
    "race_timer",
    "drift_scoreboard",
    "weather_controller",
    "vehicle_spawner"
]

[security]
enable_whitelist = false
enable_anticheat = true
kick_on_damage_anomaly = true

[logging]
level = "info"
console_output = true
file_rotation_mb = 100

[locale]
language = "en"
timezone = "UTC"

---

💻 Example Console Invocation

Launch the relay server with minimal verbosity and custom port:

./beammp-relay --port 8080 --tickrate 30 --max-clients 16 --log-level info

For verbose debugging (use with caution in production):

./beammp-relay --verbose --log-level debug --dump-sync-packets

With Docker (recommended for production):

docker run -d \
  --name beammp-relay \
  -p 8080:8080 \
  -v /path/to/config:/config \
  -e CONFIG_PATH=/config/server_config.toml \
  beammp/relay-core:2026.1.0

🤖 AI Integration (OpenAI & Claude API)

The relay core supports optional AI-enhanced features for server administrators who want to enrich gameplay:

OpenAI API Integration

• Dynamic NPC Dialogue — NPC vehicles can generate contextual radio chatter based on nearby events.
• Accident Report Summarization — The server can summarize collision logs for moderators.

[ai_services.openai]
api_endpoint = "https://api.openai.com/v1"
model = "gpt-4-turbo"
max_tokens = 150

Claude API Integration

• Traffic Flow Prediction — Claude analyzes player driving patterns and adjusts NPC density.
• Incident Moderation — Auto-generate warning messages for reckless driving behavior.

[ai_services.claude]
api_endpoint = "https://api.anthropic.com/v1"
model = "claude-3-opus-20240229"
max_tokens = 200

Note: AI features are entirely optional and run as isolated plugins. No telemetry is sent without explicit configuration.
