ChunkWalker - The Chunk Loader

ChunkWalker

Record real player behavior and have an NPC replay it exactly — including chunk loading.

What does this mod do?

ChunkWalker adds a controllable character to the game that does exactly what you showed it beforehand: walking, looking around, sneaking, swinging its arm, holding up a shield, flipping levers, opening doors — all through recording instead of manual configuration. On top of that, it permanently keeps the chunks around it loaded and simulating, whether or not a player is nearby.

No scripting, no datapack fiddling: pick up the tool, start recording, do whatever you want, stop the recording, assign it to the character — done.

Core Features

🎥 Record it, don't program it

The recording tool captures every server tick: exact position and look direction, sneaking, arm swinging, held right-click (shield blocking, drawing a bow, …), item switches in hand, and right-click interactions with levers, buttons, doors, trapdoors, and fence gates. After stopping, a small name field pops up immediately — no command needed.

🚶 Faithful playback

The character replays the recording tick-for-tick and is collision-aware — if you later place a block in its path, it won't walk through it. Optional loop playback.

🧙 Custom appearance

The character wears the actual Minecraft skin of any player and can be equipped with armor and items in both hands.

🗺️ Chunk loading

The actual namesake feature: the character keeps chunks in a configurable radius (0–6 chunks) permanently loaded and simulating via a ticket system.

🌐 Per-player language

Each player can choose, via /chunkwalker language <en|de>, which language they see ChunkWalker messages and the menu in — independent of their overall Minecraft client language. English and German are available.

🖱️ Control your way

Everything is accessible both through a graphical menu (right-click with the wand) and through chat commands (/chunkwalker …).

⚙️ Configuration (for server owners)

config/chunkwalker.json is created automatically on first start:

json
{
  "defaultLanguage": "en",
  "maxWalkersPerPlayer": -1
}

• maxWalkersPerPlayer — how many ChunkWalkers a single player may own at once (server-wide, across all dimensions). -1 = unlimited (default).
• defaultLanguage — the language players get before they've made their own choice via /chunkwalker language. Defaults to English (en), can be set to de for predominantly German-speaking communities.

The two tools

Both craftable, with custom-made 3D models.

Quick start

1. Craft the recording tool, right-click to start recording
2. Walk around, perform actions
3. Right-click again → name field appears → enter a name, done
4. Craft the ChunkWalker wand, right-click a block to spawn a new character
5. Right-click the character to open its menu → assign a recording → load a skin (optional) → start walking

Usefull commands:

• /chunkwalker language <en|de> - choose your own ChunkWalker language

ChunkWalker is available to all players by default, not just operators — spawning, recording, configuring, all freely accessible. Server owners who want to limit the number of walkers per player can use maxWalkersPerPlayer in the config (see above).
