// In-game: Press configured hotkey (default: F9) to open multiplayer menu

// 1. Start server
/start_server
 
// 2. Configure session (optional, uses synergy_profile.json by default)

// 3. Share the displayed session code with friends
// Session code appears in chat: "9B2A-4C7D-E8F1"
 
// 4. Wait for players to connect
// Connection messages appear in chat:
// "Player2 joined the session"
// "Player3 joined the session"

# 1. Open multiplayer menu (F9) or use console

# 2. Wait for synchronization
# Progress appears in UI:
# "Synchronizing world state... 45%"
# "Downloading inventory data... 78%"
# "Syncing base structures... 100%"
 
# 3. Spawn into the world
# You'll appear at the host's current location or a designated spawn point

# Player 1 places a foundation
# Action: Place Foundation at coordinates (100, -50, 200)
 
# Player 2 sees foundation immediately and can build on it
# Action: Place Corridor connecting to Player 1's foundation
 
# Both players see the same structure in real-time
# Power generation and resource consumption are shared

# Check inventory sync status

# If desync detected:
# "Warning: Inventory hash mismatch with Player2"
# "Initiating reconciliation..."
 
# Force inventory resync (rarely needed)
/force_resync inventory
 
# Check specific item counts across all players
/debug_item titanium
# Output:
# Host: 47 titanium
# Player2: 47 titanium
# Player3: 47 titanium (shared storage)

# Automatic migration occurs
# Console output:
# "Host disconnected. Initiating session migration..."
# "Player2 elected as new host"
# "Restoring session state from backup..."
# "Migration complete. Session restored."
 
# Players can continue without interruption
# All progress, bases, and inventory are preserved

# Symptom: Cannot join session, "Invalid session code" error
 
# Solution 1: Verify session code format
# Correct format: XXXX-XXXX-XXXX (12 characters with dashes)
 
# Solution 2: Check if host is still running
/synergy_status
# If host offline: "Error: Cannot connect to session"
 
# Solution 3: Verify network connectivity
/net_test <host_ip>
# Should show: "Connection successful: <latency>ms"
 
# Solution 4: Check firewall rules
# Ensure UDP port 7777 (or configured port) is open

# Symptom: Different item counts between players
 
# Solution 1: Check sync status
/sync_health
# Output shows: "Inventory hash mismatch detected"
 
# Solution 2: Force reconciliation
/force_resync inventory
# Wait for: "Inventory reconciliation complete"
 
# Solution 3: If persistent, restart session with backup
/restore_backup 0  # Most recent backup

# Symptom: Delayed actions, rubber-banding
 
# Check current latency
/synergy_status
# Look for: "Latency: 300ms+" (problematic)
 
# Solution 1: Adjust network settings in config
{
  "network": {
    "max_latency_ms": 200,  // Increase tolerance
    "packet_loss_tolerance": 0.1  // Allow more packet loss

# Symptom: One player places base parts, others don't see them
 
# Solution 1: Check base sync status
/debug_base
# Output: Lists all base components and which players see them
 
# Solution 2: Force base state resync
/force_resync base
 
# Solution 3: Verify collaborative_placement setting
{

  }
}
 
# Solution 4: Check for conflicts
/base_conflicts
# Resolves any placement conflicts automatically

# Symptom: BepInEx console shows no Deep Synergy messages
 
# Check BepInEx log
# Location: BepInEx/LogOutput.log
 
# Common causes:
# 1. Missing dependencies
#    Error: "Could not load [DeepSynergy.Core.dll]"
#    Solution: Reinstall mod, ensure all DLLs are present
 
# 2. Incompatible BepInEx version
#    Error: "BepInEx version mismatch"
#    Solution: Update to BepInEx 6.0.x
 
# 3. Game update broke IL2CPP hooks
#    Error: "Failed to hook [MethodName]"
#    Solution: Wait for mod update or downgrade game version
 
# 4. Conflicting mods
#    Disable other mods one by one to identify conflicts
