Omni Dev

Omni Dev – The In-Game Developer Toolkit

Omni Dev ist a utility mod designed by developers, for developers.
Whether you are making a massiv mod, a coustom map, or just want to test vanilla mechanics.
All generated .nbt an .json files are automatically exported to your saves/YOUR_WORLD/generated/omnidev/ folder.

The Workflow
With Omni Dev, creating a fully functional dungeon is as easy as:

Build your structure and place your chests.
Generate custom loot using the in-game GUI (/dev_lootgen)
Assign the saved loot table to a chest just by looking at it (/dev_setloot)
Select your building using the Omni Dev Wand.
Save it! You now have a completet .nbt structure with fully working, randomzed loot tables inside.

Commands

Structure Tools:

/dev_wand – Gives you the selection stick to mark Position 1 and Position 2.
/dev_pos1 & /dev_pos2 – Manualy set your selection boundaries.

/dev_spawn [structure_id] – Spawns any structure in the game at your location (supports Vanilla and all Modded structures).
