ModSync - Chat-Based Mod Synchronization

A plugin for Mage Arena that synchronizes mods between host and clients.

NEW: FRIENDSMODE configuration! Press F8 to disable all kicking/leaving functionality of modsync, to guarantee your private lobbies arent messed with by modsync.

Features

• Automatic Detection: Detects when players join and automatically checks their mod compatibility
• Lobby Lock: Host can enable lobby lock (F9) to kick players with mismatched mods (clients get 10 seconds to respond to mod requests)
• Visual Feedback: Shows success/error messages in the game UI
• Renames Lobbies: Automatically names lobbies MODDED: (list of mods)

How It Works

For Hosts:

1. When a player joins, ModSync sends a mod request to the player.
2. If the player has ModSync, they respond with their mod list
3. Host compares mod lists automatically and either accepts or kicks the player.

• Mods with the "all" tag will be considered when matching mod lists. This means that client side mods should not affect the compatibility between host and player.

For Clients:

1. When joining a lobby, clients automatically send their mod list to the host
2. Clients respond to mod requests from the host
3. If mods don't match, clients receive a mismatch message

• Most client side mods should be fine to run without getting a mismatch error.

Installation

1. Install BepInEx for Mage Arena
2. Place ModSync.dll in the BepInEx/plugins folder

Usage

For Hosts:

• Press F9 to toggle lobby lock on/off

• When lobby lock is enabled, players with mismatched mods will be automatically kicked

• Press F8 to toggle FRIENDSMODE. This will disable all kicking/leaving functionality so modsync does not mess up your private lobbies.

• This can also be modified in the config file.

For Clients:

• No manual intervention required
• ModSync automatically handles synchronization when joining lobbies
• Check the game logs for detailed ModSync information

Configuration

If your mod can be considered a "cheat" - You MUST add the "all" tag and follow below, or you risk your mod being removed.

Mod developers can specify their mod's sync type by adding a static field or property named modsync:

public static string modsync = "all"; // Requires matching on both host and client - This is what is considered when syncing lobbies
public static string modsync = "host"; // Only required on host - These do not count for syncing lobbies
public static string modsync = "client"; // Only required on client - These do not count for syncing lobbies

here is an example of how an all mod should act:

namespace ExampleMod
{
    [BepInPlugin("com.example.mymod", "My Example Mod", "1.0.0")]
    [BepInProcess("MageArena.exe")]
    [BepInDependency("com.magearena.modsync", BepInDependency.DependencyFlags.HardDependency)]
    public class ExampleMod : BaseUnityPlugin
    {
        // This mod requires both client and host to have it
        public static string modsync = "all";
        
        private void Awake()
        {
            // ModSync dependency is guaranteed by BepInEx hard dependency
            // If ModSync is not present, this mod won't even load
            Logger.LogInfo("ModSync found! Initializing mod...");
            // Your mod initialization code here
        }
    }
}

Note the Bepinex Hard Dependency. This is REQUIRED for mods that can be considered cheats.
