Van Haven Client Core

by Puremask

Van Haven Client Core is a NeoForge client-side mod for Minecraft 1.21.1 that hooks custom multi-battles and cosmetics into the Van Haven Cobblemon server.

What it does

On a Van Haven server, the client mod supplies the client-side hooks needed for custom multi-battles. Cosmetics can be added through a data resource pack, so new looks do not require changes to the mod itself. The mod runs on the client only: a server does not need it, and players connect to the server without installing anything extra.

The mod builds on the libraries and companion mods its author lists, including Cobblemon, Mega Showdown, GeckoLib and Accessories, together with a recent NeoForge build. Cosmetics also draw on Pi-Eta Pi's Cosmetics and Eclipse Core Client functionality. Custom raid work outside Van Haven needs a separate raid mod, which this one does not provide.

Files are published for NeoForge only, and the latest file is 1.1.1 for 1.21.1, released 2026-06-13. The first release came out on 2026-06-04. The mod is released under All rights reserved and is not open source.

Key features

  1. Custom multi-battle hooks

    Client-side hooks let the custom multi-battles of the Van Haven server run on each player's client.

  2. Data-driven cosmetics

    Cosmetics can be added through a data resource pack, and the cosmetic settings can be adjusted in many ways.

  3. Cobblemon integration

    The mod is written for the Van Haven Cobblemon server and works alongside Cobblemon and Mega Showdown.

Questions

Does Van Haven Client Core need to be on the server?

No. Only the player's game needs it, and servers run without it.

Which libraries does Van Haven Client Core depend on?

The author lists NeoForge, Cobblemon, Mega Showdown, GeckoLib and Accessories as components the mod works with.

Can new cosmetics be added without changing the mod?

Yes. Cosmetics are added through a data resource pack, which the cosmetic system reads at load time.

The client mod for the Van Haven Cobblemon server. You need a custom raid mod for this to work outside Van Haven.
