Hytale Prefabs

Reference for Hytale's prefab system — creating, saving, loading, and managing reusable structures via in-game commands.

Source: <https://hytalemodding.dev/en/docs/guides/prefabs>;

Quick Reference

Task Approach
Create a new prefab world /editprefab new <world_name>
Save a prefab /prefab save (use selection brush first)
Load a prefab /prefab load
List all prefabs /prefab list
Delete a prefab /prefab delete
Exit prefab editing world /editprefab exit
Select a prefab area Use the selection brush in the editing world
Paste a prefab Use the Paste brush, press E to select from menu
See command options Append --help to any command (e.g., /prefab save --help)

Key Concepts

  • Prefab editing world — A dedicated world created for building and editing prefabs. Created with /editprefab new.
  • Prefabs — Physical structures saved as JSON files. A single editing world can contain multiple prefabs.
  • Selection brush — In-game tool used to select the area to save as a prefab.
  • Paste brush — In-game tool used to place saved prefabs. Press E to open the selection menu.

Basic Workflow

  1. /editprefab new myprefabworld — Create a new prefab editing world
  2. Build the structure you want in the editing world
  3. Use the selection brush to select the area
  4. /prefab save — Save the selected area as a prefab
  5. /editprefab exit — Exit the editing world
  6. Use the Paste brush, press E to select the prefab from the "server" dropdown (top-right of menu)

Commands

/prefab

Manages prefab files on disk.

Subcommand Description
save Saves the prefab to the file system
load Loads a prefab into the game
delete Deletes the prefab from the file system
list Lists all prefabs in the file system

/editprefab

Manages the physical structure editing workflow.

Subcommand Description
new Creates a new prefab editing world from scratch
load Creates a new editing world with an existing prefab pasted in
exit Exits the current prefab editing world
select Selects the prefab area the user is looking at (within 200 blocks)
save Saves the current prefab using the existing or selected area
saveui Opens the save UI for managing all prefabs in the current world
saveas Saves the selected prefab into a new file
kill Despawns all entities in the currently selected prefab
setbox Sets the bounding box of the currently selected prefab
info Shows information about the currently selected prefab
tp Opens teleport UI to jump to a prefab in the current editing world
modified Lists all modified prefabs with unsaved changes

Use --help at the end of any command to see all available options (e.g., /editprefab save --help).

Known Issues

  • After saving edits to an existing prefab, the prefab may not reflect changes immediately. Workaround: exit and re-enter the world.
  • When pasting a prefab, it may not always display accurately. Workaround: press T to toggle the material view; usually at least one view is correct.
  • /prefab delete may error with Assert not in thread.

Edge Cases & Gotchas

  • The world name in /editprefab new <world_name> is the world name, not the prefab name. Worlds can contain multiple prefabs.
  • Saved prefabs appear in the "server" dropdown of the Paste brush menu (top-right).
  • Prefabs are saved as JSON files to the server file system.
  • This is primarily a command-based workflow — there is currently no public Java API for programmatic prefab manipulation from plugins.
