Barrel Harvest

Barrel Harvest v1.4.0

Open the settings menu (Book UI)

/trigger bh_trigger set 1

This gives you a clickable written book — right-click to open it. Click any button to toggle that setting. Feedback appears as a single line in chat when you close the book. No more chat spam from the old 90-line menu re-print.

The book has 5 pages:

1. Main Controls — enable/disable, interval presets, chance presets, fine-tune buttons
2. Select Wood Type — pick which wood you want to configure loot for
3. Loot Toggles — enable/disable log, planks, stripped log, stick, sapling, leaves, apple for the selected wood
4. Shelf Upgrades — explains the shelf upgrade system
5. Help — quick reference and uninstall command

If your inventory is full, the book drops on the ground — pick it up and right-click to open.

Server note: The book uses /give, which requires function-permission-level ≥ 2 (the default). If your server has it set lower, the book won’t appear — use the trigger shortcuts below instead.

Bugs

• May miss pots if they are outside the scan radius (default 10×10×4 volume around each player).
• Barrel must have space for loot; harvests are skipped when full.

Uninstall (OP/admin) — run BEFORE removing the pack

/function barrelharvest:uninstall

This stops the pack and removes the three scoreboard objectives (bh_timer, bh_config, bh_trigger) so nothing lingers in the world. After running it, disable/delete the datapack:

/datapack disable barrelharvest

Interval and Chance Presets

Interval and chance are controlled independently. Pick a preset for each, or fine-tune with the +/- buttons.

Interval presets (how often harvest attempts happen)

| Preset | Interval | Real time |
|——–|———-|———–|
| Fast | 100 ticks | 5 seconds |
| Medium | 400 ticks | 20 seconds |
| Slow | 1200 ticks | 60 seconds |

Fine-tune: +/- 20 ticks per click (min 100, max 4000).

Chance presets (odds per harvest attempt)

| Preset | Chance |
|——–|——–|
| Fast | 100% (every attempt harvests) |
| Medium | 50% |
| Slow | 20% |

Fine-tune: +/- 5% per click (min 5%, max 100%).

Combining presets

Since interval and chance are independent, you can mix them:

• Fast interval + Fast chance — harvests every 5 seconds, always succeeds (very high output)
• Slow interval + Fast chance — harvests every 60 seconds, always succeeds (steady, low maintenance)
• Fast interval + Slow chance — attempts every 5 seconds, only 20% succeed (frequent but unreliable)
• Medium interval + Medium chance — balanced default

Shelf Upgrades (Minecraft 26.2+)

Place a Shelf block (any wood variant: oak, spruce, birch, jungle, acacia, dark oak, mangrove, cherry, pale oak, bamboo, crimson, warped) directly adjacent to the barrel — north, south, east, or west side. Put upgrade items into the shelf’s 3 slots. The datapack reads the shelf contents during each harvest and applies bonuses:

| Item | Effect |
|——|——–|
| Diamond | Double drops — the harvest produces a second copy of whatever was rolled |
| Glowstone Dust | Extra log — guarantees one additional log drop per harvest (if logs are enabled for that wood) |
| Bone Meal | 50% chance to duplicate the dropped item — more output per harvest cycle |
| Lapis Lazuli | Extra leaves — guarantees one additional leaves drop per harvest (if leaves are enabled) |

How it works

• The pack checks all 4 horizontal sides of each barrel for shelf blocks (#minecraft:wooden_shelves tag).
• It reads the shelf’s Items[] NBT to detect which upgrade items are present.
• Multiple upgrades stack — a shelf with both diamond and glowstone gives double drops AND an extra log.
• You can mix items across multiple shelves (e.g. diamond on the north shelf, lapis on the east shelf).
• Upgrades only work on Minecraft versions that have the Shelf block (snapshot 25w31a / 26.2+). On older versions, shelves simply don’t exist and upgrades are silently skipped — the pack still works normally.

Setup example

[Shelf: Diamond] [Barrel] [Pot: Oak Sapling]
                  [Shelf: Glowstone Dust]

This barrel would get double drops + an extra oak log every harvest cycle.

Compatibility

• Targets Java Edition 1.21.4 through 26.2 (pack_format 107, supported_formats 48–107).
• The pack never summons entities (no armor stands, markers, or display entities), so there is nothing to clean up in the world itself — only the three scoreboard objectives, which barrelharvest:uninstall removes.
• Tested syntax surface on 26.2: random, loot insert, data get block ... Items, potted_* block IDs, written_book_content component, SNBT text components, scoreboard, return.
• If anything behaves oddly on 26.2, disable the pack before removing it (/datapack disable barrelharvest), then run /function barrelharvest:uninstall while it’s still loaded, then delete the folder.

Notes

• Most settings are easiest to change via the menu book.
• Harvest attempts are per-player and scan a 10×10×4 volume around each player.
• Debug mode can be toggled with /scoreboard players set #debug bh_config 1 to see harvest attempts in chat.
• A particle-only scan (detect/scan_5x5_area) runs every 100 ticks per player to sparkle on valid pot+barrel combos. If you want maximum performance on a busy server, you can disable this visual feedback by gating it behind #debug (see tick.mcfunction).
• check out WASD Bonsai pots also, very cool pack with its own models, mine is just vanilla
