Loot Injector

Inject custom loot into any chest in the game — vanilla or modded — using simple JSON config files. No coding required.

✦ Features

• Inject into any loot table — dungeons, bastions, strongholds, villages, shipwrecks, modded structures, mob drops, fishing loot, and more
• Works with every mod — uses Forge's item registry with a multi-stage lookup so items from any mod are supported
• Weighted probability — each item has its own independent drop chance (0.01%–100%) per chest opening
• Float counts — min/max stack sizes accept decimal values (e.g. 1.5 averages to 2)
• Full NBT support — attach any SNBT tag to items; required for mods that use generic items with NBT variants
• Custom Loot Chests — define named chest configs and give them to players via command; items are pre-rolled per give
• In-game GUI editor — browse, add, edit, and delete loot rules without ever touching a file
• Live JSON preview — Raw JSON tab shows the exact file content as you edit
• Hot-reload — apply config changes without restarting the server via /structureloot reload
• Import / Export — share config sets as ZIP profiles with /structureloot export and import
• Validation command — /structureloot validate scans every item ID and reports errors instantly
• Debug commands — /structureloot debug items lists all items from any mod; debug item tests a single lookup

✦ How It Works

Place a .json file in .minecraft/config/structureloot/pools/ and the mod injects your items into that loot table at runtime — no data pack, no /reload, no restart needed.

{
  "target_loot_table": "minecraft:chests/simple_dungeon",
  "enabled": true,
  "inject_items": [
    { "item": "minecraft:diamond",  "weight": 10.0, "min_count": 1.0, "max_count": 3.0 },
    { "item": "examplemod:rare_sword", "weight": 2.0, "min_count": 1.0, "max_count": 1.0,
      "nbt": "{display:{Name:'{\"text\":\"Ancient Blade\"}'}}" }
  ]
}

The weight field is a percentage chance per chest opening (not a pool weight). weight: 10.0 means a 10% chance each time that chest is opened.

✦ Custom Loot Chests

Define a named chest config in config/structureloot/chests/ and give it to any player via command:

/structureloot chest get mythic_chest

The player receives a named chest with pre-rolled items inside. The GUI lets you manage configs, add items, set rolls, and edit everything without editing files directly.

✦ Commands

All commands require OP level 2.

✦ GUI Editor

Open with the K keybind (rebindable in Controls → Structure Loot Injector).

The editor provides a full three-panel interface:

• Loot Pools — manage injection rules per loot table
• Entries tab — add/edit/remove items with weight bars and count ranges
• Raw JSON tab — live syntax-coloured view of the config file
• Custom Chests — manage named chest configs with guaranteed and weighted random item pools

✦ Finding Item IDs

1. Press F3+H in-game to enable advanced tooltips
2. Hover over any item — the registry ID appears at the bottom of the tooltip
3. For mods with NBT-based item variants, the full NBT tag is also shown

Or use the built-in command:

/structureloot debug items 

✦ Compatibility

• Server-side only (clients do not need the mod installed)
• Compatible with all mods that use standard Forge item registration
• Uses Forge's Global Loot Modifier system — no conflicts with other loot mods
