Nexus Characters – Cross-World Progression

Welcome to Nexus Characters! This mod fundamentally changes how you experience Minecraft by shifting the focus from world-bound progression to character-bound progression.

Instead of starting from scratch every time you create a new world, Nexus Characters allows you to seamlessly carry your inventory, stats, and identity across all your single-player saves and multiplayer servers. Build your character, explore infinite worlds, and never lose your hard-earned progress again.

✨ Core Features

Character Creation

Create unique identities for your different playthroughs. When making a new character, you have complete control over their identity and playstyle:

• Custom Naming: Give your character a unique identity.
• Skin Syncing: Simply input an existing Mojang username, and your character will automatically adopt that skin.
• Bound Gamemodes: Gamemodes (Survival, Creative, Adventure) are tied to the character, rather than the world.

Cross-World Progression

Your character’s journey doesn’t end when you leave a world. Everything that defines your character travels with them:

• Health and hunger stats
• Experience levels (XP)
• Full inventory and equipped armor
• Advancements and statistics

Hardcore Characters

Love the thrill of Hardcore but hate losing a beautiful world you spent hours building? Nexus Characters introduces Hardcore Characters.

• If your Hardcore Character dies, they are permanently erased from your character list.
• The World Survives: The world they died in remains perfectly intact. You can roll a brand-new character, travel to that same world, and find your fallen character’s base (or avenge them!).

🚀 Extended Capabilities

Deep Mod Compatibility

Nexus Characters doesn’t just save vanilla data. It integrates deeply with your favorite mods to ensure that external progression is saved directly to your character. For example, if you are playing with Cobblemon, your party of Pokémon and your PC boxes will travel with your character across dimensions and worlds!

Multiplayer Support

Take your characters online! Nexus Characters is fully compatible with dedicated servers. Server owners can install the mod to allow players to bring their cross-world characters into the community, or restrict servers to specific character types.

Legacy Data Migration

If you are adding Nexus Characters to an existing world where you already have progress, you can easily inherit your old data!

• How to Inherit: Create a new character and set the Character Name to perfectly match your Minecraft Username (the account that originally played in that world).
• Security: You can only inherit your _own_ legacy data. For example, if you are Player1 and your friend is Player2, you cannot create a character named Player2 to steal their progress.

Important: When you do this, your character’s current progress will be completely overwritten by the legacy data from that world. If you want to enter a legacy world but keep your cross-world character’s existing progress, ensure your character is named differently from your Minecraft username!

Autosave Interval Command (Server/LAN only)

If you are hosting a Server or a LAN world, you can manage how often non-vanilla data is synced to players:

• /nexus saveinterval <time in seconds> _(Default: 30s)_ Alters the time between autosaves for data coming from external mods (e.g., catching a Pokémon or updating your Pokédex).

Syncing Delay: Even if you define the interval to 1 second, it still takes time for the server to send the data to the client, and for the client to save it properly to disk. Because of this, you should wait 1 to 2 minutes before disconnecting after doing something important related to mods to avoid losing progress! Also, the shorter the interval, the heavier will be server load.
