EnderChest → Obsidian Farm

EnderChest → Obsidian Farm is an automation mod that turns the repetitive process of placing and breaking Ender Chests into a hands-free obsidian farm. It's built for players who need large amounts of obsidian — for bases, vaults, traps, crystal PvP, or server economies — and it automates the whole loop while staying fully configurable.

⚠️ This is a client-side automation/macro mod. On many multiplayer servers, automating actions like this is against the rules and may be detected as cheating. Use it on singleplayer or servers where it's allowed.

Core Functionality

The mod runs a continuous cycle:

1. Places an Ender Chest on the ground in front of you.
2. Breaks it with your diamond pickaxe.
3. Collects the dropped obsidian.
4. Repeats automatically.

If an Ender Chest is already sitting in the spot, it breaks that one instead of failing — so you can pre-place chests and let it run.

Automation Features

• Automatic placement – places Ender Chests on a valid floor spot in the direction you were facing when you started.
• Automatic breaking – mines chests with the diamond pickaxe in your hotbar (falls back to any pickaxe).
• Obsidian storage – when your inventory fills, it dumps obsidian into nearby shulker boxes, moving on to the next shulker when one fills up.
• Ender Chest refilling – pulls fresh Ender Chests out of a nearby chest when your hotbar runs low.
• Smooth rotation – eases your view toward each target (placement spot, chest, shulker) instead of snapping, for more natural movement.
• All game modes – progressive mining in Survival/Adventure, instant breaking in Creative, idles in Spectator.
• Works through GUIs – keeps running even while an inventory or menu screen is open.
• Auto-recovery – validates each step and stops cleanly (with a chat message) on dead ends instead of getting stuck.

Safety

• Interference detection – pauses the farm when another player comes within a configurable radius (any game mode, including spectators), and resumes when they leave.
• Auto-leave – optionally disconnects from the server instantly when a player is detected.
• Auto-reconnect – optionally rejoins the server after a disconnect (e.g. a spam kick) once the configured delay passes, then resumes farming.
• Anti-spam cooldown – a configurable delay between auction-house listings to avoid command-spam kicks.

Server / Economy Integration

For economy SMP servers, the farm can run a full hands-free supply chain:

• Auto-restock – when out of Ender Chests, runs your server's order command (e.g. /order enderchest), navigates the GUI, collects the chests, banks the spares, and resumes.
• Auto-sell – lists obsidian on the auction house with /ah sell <price>, automatically clicking the "Confirm Listing" button, and pulling obsidian back out of the shulkers to sell. Price is per item (the listing price is price × stack size). It reads chat to detect when the AH is full ("too many listed items") and when listings sell ("bought your …"), listing more as slots free up. Trigger it any time with /enderfarm sell now.

Containers behind walls are ignored — the farm only opens shulkers and chests it has a clear line of sight to.

Performance

• Lightweight — negligible FPS impact.
• Adjustable action delays and rotation speed for server compatibility.
• Configurable interaction range and detection distance.

Setup

Stand on a flat platform facing where chests should be placed, with — within ~4.5 blocks — a diamond pickaxe and Ender Chest in your hotbar, a shulker box for obsidian, and (optionally) a chest stocked with Ender Chests for refilling. Press the toggle key.

All settings persist to config/enderfarm.json.

Keybind

• O (default) – toggle the farm. Rebindable in Options → Controls → Ender Obsidian Farm.
