Project ZombCraft

Project ZombCraft

Play Project Zomboid as Minecraft's Steve. Project ZombCraft connects Project Zomboid Build 42 with a real Minecraft: Java Edition running beside it. Project Zomboid stays the world and the zombies; Minecraft brings Steve, his movement, blocks, inventory, survival and HUD.

This is the Minecraft half (Project-ZombCraft for Fabric). You also need the Project Zomboid half from the Steam Workshop.

Two Minecraft versions (download the file for yours; the Project Zomboid mod is the same for both):

Single player only for now. Multiplayer is in development.

You need

• Project Zomboid Build 42 (42.21 or later) on Windows, with ZombieBuddy, Project Viewpoint and Project ZombCraft from the Steam Workshop
• Minecraft: Java Edition in Prism Launcher, one of:
• 26.3 with Fabric Loader 0.19.5, Fabric API, GeckoLib 5.5.7, this mod's +mc26.3 file, and Java 25. Better Combat is optional, for its melee animations.
• 1.20.1 with Fabric Loader 0.16 or later, Fabric API for 1.20.1, GeckoLib 4.8.4 for 1.20.1, this mod's +mc1.20.1 file, and Java 17. Add the other Fabric 1.20.1 mods you want (Better Combat is not supported on 1.20.1).

Install

1. In Prism Launcher, create a Minecraft 26.3 or 1.20.1 instance with Fabric: in the New Instance dialog pick the version and, under Mod loader, select Fabric. The instance's Version tab must list Fabric Loader next to Minecraft. Without it Minecraft starts as plain vanilla and ignores every mod.
2. Add Fabric API, GeckoLib (for that Minecraft version) and this mod's file for that version to the instance (Prism's Mods → Download mods, or put the jars in its mods folder).
3. Subscribe to Project ZombCraft, ZombieBuddy and Project Viewpoint on the Steam Workshop and enable all three in Project Zomboid's Mods menu. ZombieBuddy needs a one-time setup: follow its Workshop page.

How to play

1. Start Project Zomboid. Its main menu lists your Minecraft instances that have this mod: press Play and it starts    yours (Prism Launcher, MultiMC and PolyMC). Project Zomboid never starts Minecraft by itself. With CurseForge, the    Modrinth App or Mojang's launcher, start the instance yourself and Project Zomboid waits for it.
2. While Minecraft loads, Project Zomboid shows its loading screen. Minecraft runs in its own window; leave it running.
3. Start a new game. Before character creation, choose Steve (Minecraft's character: no character creation, Minecraft's    inventory and rules, Minecraft's starter kit) or Zomboid survivor (Project Zomboid's own character, played in first    person; it never becomes Steve). A character keeps its choice: to change it, start a new character.
4. You start in first person. As Steve, Minecraft's HUD is there as soon as Minecraft has opened the save's world.

The first time, ZombieBuddy asks you to approve Project-ZombCraft's Java code: approve it.

Each Project Zomboid save has its own Minecraft world, so Steve's inventory and your blocks stay with that save. Pausing Project Zomboid pauses Minecraft too. Minecraft closes itself, saving its world, a few seconds after Project Zomboid exits.

Troubleshooting

• Minecraft opens its normal title screen and nothing happens. The mod isn't loaded: check that the instance's Version tab lists Fabric Loader.
• Project Zomboid shows no Steve. Check that ZombieBuddy, Project Viewpoint and Project ZombCraft are all enabled, that you approved Project-ZombCraft in ZombieBuddy's prompt, and that the box at the top of the screen doesn't say something is missing.
• 1.20.1 with other mods: something looks wrong or breaks. Try without the other mods first; if it works then, please report which mod.
• Minecraft crashed or closed. Start it again from the same Prism instance, wait for it to load, then press O again in Project Zomboid. If that doesn't reconnect, load the save again.
