MonsterTrainManifestExtension

Enable fine-grained control of blocked contents and features for Monster Train mods via modmanifest.json.

Basic usage

1. Add this NuGet package to your project: https://www.nuget.org/packages/MonsterTrainManifestExtension

2. Modify your modmanifest.json according to this documentation. This is an example of modified modmanifest.json file for Arcadian Clan mod:

   {
     "ModId": 2205081572,
     "Title": "Arcadian Clan",
     "Tags": [
       "Clan",
       "Monsters",
       "Spells",
       "Artifacts"
     ],
     "CosmeticOnly": false,
   
     "BranchMetagameSave": true,
     "ReportRunSummaryAsModded": "OnlyWhenNewClansAreInvolved",
     "BlockCreatingCustomChallenge": true,
     "BlockHellRush": false,
     "BlockAchievements": false,
     "BlockWinStreaks": false,
     "BlockCovenantRank": false,
     "BlockCompendiumVictoryTracking": false,
     "BlockCompendiumCardTracking": false,
     "BlockLocalStats": false
   }

3. Make sure to publish your mod with MonsterTrainManifestExtension.dll and Newtonsoft.Json.dll in plugins directory.

Advanced usage

The BranchMetagameSave option isolates the modded progress file. That alone already protects the players from having a save with modded data which might result in an invalid save on the base game synced over the Steam Cloud.

But if you'd like to step further and extensively modify the MetagameSaveData class in MT, you can follow these steps to ensure it's safe to modify them:

1. Enable BranchMetagameSave option ("BranchMetagameSave": true)

2. Add [BepInEx.BepInDependency("com.nedsociety.monstertrainmanifestextension")] attribute to your class:

       [BepInEx.BepInDependency("com.nedsociety.monstertrainmanifestextension")]
       [BepInEx.BepInPlugin("com.my.mtmod", "MyMtMod", "1.0.0.0")]
       public class MyMtMod : BepInEx.BaseUnityPlugin
       {
              // ...

3. From your Awake(), or Initialize() if you're using Trainworks, check if MonsterTrainManifestExtension.MonsterTrainManifestExtension.Instance.Enabled is true. This property indicates whether you're safe to modify the save file or not.

   if (MonsterTrainManifestExtension.MonsterTrainManifestExtension.Instance.Enabled)
   {
       // Modify the MetagameSaveData class or instance. 
       // You can access the instance via Trainworks.Managers.ProviderManager.SaveManager.GetMetagameSave()
   }

4. Done! Your modifications will be safely serialized into an isolated save.
