Hi guys! 👋 Today I want to introduce you to my addon for Modjam 2026:

This addon adds a working Mobile Warehouse to the Happy Ghast. When you dismount the Ghast, a structure with chests and storage deploys on the ground below. When you remount, everything saves automatically and the structure disappears.
I spent a lot of time building all of this in JavaScript, so I hope you enjoy it.

HAPPY GHAST PICTURE:

Features:

The Happy Ghast deploys a 8x8 mobile warehouse when you dismount on the ground
Your personal warehouse is automatically saved and reloaded every time you use it
The Ghast flies at a fixed 7x speed for fast and smooth exploration
Up to 13 players can ride together on a single Ghast
Smart obstacle detection scans the area before deploying to prevent damaging existing structures or terrain
Automatic mid-air fall protection grants Slow Falling and Resistance whenever you dismount in flight
Automatic pre-save validation ensures empty space or ungenerated areas are never saved over your items
Emergency auto-save secures all your chests and items immediately if the Ghast dies while open
Automatic background saving updates your storage every 5 seconds while the warehouse is open
Owner lock protection prevents unauthorized players from piloting or interacting with your Ghast
Built-in Pack Settings (Subpacks) allow you to choose between Anti-Duplication mode or Multi-Warehouse mode
Includes a quick reset command (/function forced_reset_chests_ghast) to restore default storage at any time

How to use

Saddle the Happy Ghast and ride it (using the Harness)
Fly to an open area with no blocks around
Dismount and the Warehouse will open
Remount to save and close it
If you need to reset your warehouse use /tag @s add sodhg_forced_reset_chests_ghast in chat or /function forced_reset_chests_ghast
