Create Ore Excavation Deposits

Multi-chunk ore deposits for Create Ore Excavation — distance-driven richness, Xaero map overlay, per-player reveal policies, full multi-dimension support.

What you get

Multi-chunk deposits — irregular Perlin-shaped blobs of 2–40 chunks, all sharing one ore type.
Distance gradient — log-curve drives deposit size, richness, and which ores are eligible.
Per-chunk gradient — the core chunk is peak yield; outer chunks fade down to a configurable floor (default 30 %).
Biome-aware — You can configure spawn biomes (In default config: iron in mountains/taiga, gold in badlands/savanna, nether_quartz in nether biomes, etc.).
Multi-dimension — You can configure recipie's dimensions
Reveal policies — four modes per type: always / on_discovery (walk near) / on_proximity (visible while close) / on_prospect (Vein Finder reveals). Per-player tracking.
World-map overlay — coloured chunks on Xaero's World Map with diagonal stripes, alpha-fade as the vein depletes, and a hover tooltip showing remaining / initial units per chunk.
Reproducible patterns — per-dimension depositSeed override lets you copy a layout from one world to another via /coedeposits regenerate <seed>.
Per-type placement mode — managed (our blob algorithm) or coe (let vanilla COE place, we just track for the map).
Server-authoritative — all state in SavedData, full client-side sync.

Required

Commands

All /coedeposits subcommands require permission level 2 (standard OP via /op <player>).

Command	What it does
`/coedeposits tier`	Show distance + tier fraction at the player's position.
`/coedeposits list`	Top-10 nearest known deposits in the current dimension.
`/coedeposits here`	Info about the deposit owning the player's current chunk.
`/coedeposits scan`	Re-prospect around the player (no wipe).
`/coedeposits regenerate [seed]`	Wipe the current dimension + fresh prospect-scan. Optional seed override locks placement for reproducible patterns.
`/coedeposits seed`	Print effective deposit seed + whether it's an override or world seed.
`/coedeposits refill` / `refill all`	Restore the deposit at the current chunk / every deposit in the dimension.
`/coedeposits delete here` / `delete chunk`	Remove a whole deposit / single chunk from a deposit.
`/coedeposits place [<type> [<pos> [<amount> [<chunks>]]]]`	Admin-place a deposit. `amount<0` → infinite vein, `amount>0` → exact unit budget.
`/coedeposits replenish <rate>` / `replenish all <rate>`	Set the per-hour replenish rate for the deposit under the player, or for every deposit in the dimension. `0` disables.

Configuration

All three config files auto-create on first launch with sensible defaults. You don't need to touch them to play — they exist for tuning and per-server customization.

Deposit registry

config/coedeposits/deposits.json — top-level JSON map of deposit ids → type bodies. Edit + /reload to refresh in-game. Per-entry parse errors are logged but don't break the rest.

Real entry from the bundled defaults — iron ore in overworld mountains/taiga/hills:

{
  "coedeposits:iron": {
    "vein_recipe": "coedeposits:iron_vein",
    "items": [{"item": "minecraft:raw_iron", "weight": 1, "min": 1, "max": 1}],
    "placement": "managed",
    "dimensions": "minecraft:overworld",
    "distance": {"min": 0, "max": 99999},
    "size_chunks": {"min": 4, "max": 30},
    "per_chunk_units": {"min": 20000, "max": 200000},
    "weight": 150,
    "map_color": 12895428,
    "biome_filter": ["c:is_mountain", "minecraft:is_taiga", "minecraft:is_hill"]
  }
}

A more advanced example — nether quartz, restricted to the nether dimension, hidden until found with a Vein Finder:

{
  "coedeposits:nether_quartz": {
    "vein_recipe": "coedeposits:nether_quartz_vein",
    "dimensions": "minecraft:the_nether",
    "size_chunks": {"min": 4, "max": 25},
    "per_chunk_units": {"min": 25000, "max": 220000},
    "weight": 220,
    "map_color": 15790824,
    "biome_filter": ["minecraft:is_nether"],
    "reveal": "on_prospect"
  }
}

Field reference:

Field	Purpose
`vein_recipe`	COE VeinRecipe id applied to the chunk's OreData.
`placement`	`managed` (our blob algorithm) or `coe` (vanilla COE places, we track for the map). Default `managed`.
`dimensions`	Allow-list of dimension ids. `"minecraft:overworld"` or `["minecraft:the_nether", "minecraft:the_end"]`. Empty = any enabled dimension.
`distance`	Block distance window from spawn (managed only).
`size_chunks`	Blob size range; tier-lerped between min and max.
`per_chunk_units`	Per-chunk unit budget. `max` optional — without it, budget grows as `min × (1 + tier × unbounded_growth)`.
`weight`	Weight in the weighted pick among eligible managed types.
`map_color`	RGB int for the world-map overlay.
`biome_filter`	Any-of biome tag list. Empty = any biome.
`reveal`	`always` / `on_discovery` / `on_proximity` / `on_prospect`. Defaults to the global `reveal_mode`.
`vein_recipes`	Alternative to `vein_recipe` — pool of `[{recipe, weight}, …]` for per-chunk weighted picks across multiple ores.
`vein`	Inline VeinRecipe (`display_name`, `amount_multiplier_min/max`, `icon`). Synthesised by the bundled virtual datapack — no separate file needed.
`drilling`	Inline DrillingRecipe (`outputs: [{item, chance, count}]`, `ticks`, `stress`). Synthesised alongside `vein`.
`fillers`	Optional `[{weight}]` — adds patchy empty "tailings" chunks. Default off.
`replenish_rate_per_hour`	Units restored per hour to drilled chunks while loaded. Capped at each chunk's original yield. Default `0` (off).

Server tuning

config/coedeposits-common.toml:

# Distance curve — log-scale: tier ≈ 0.5 at base_radius, ≈ 1.0 at max_radius
base_radius = 1000.0
max_radius = 25000.0

# Per-chunk roll to become a deposit core
core_spawn_probability = 0.02

# Per-chunk gradient floor — edges get this fraction of the core's peak
edge_amount_mul = 0.3

# Pre-scan radius around spawn on server start (0 = disabled, max 16000)
prospect_radius = 2000

# Open-ended growth when per_chunk_units.max is absent
unbounded_growth = 50.0

# Default reveal policy (per-type override in deposits.json)
reveal_mode = "ALWAYS"
proximity_reveal_blocks = 256
discovery_radius_blocks = 24

# Dimensions where the mod is active
enabled_dimensions = ["minecraft:overworld", "minecraft:the_nether", "minecraft:the_end"]

# Max pending placements materialised on the main thread per tick from the
# async prospect queue. Dry-run picking runs off-thread; this only throttles
# the hand-off step. Raise to drain the queue faster after a large /regenerate;
# lower if you see tick spikes on weak CPUs.
prospect_chunks_per_tick = 256

# ── Logging toggles ─────────────────────────────────────────────────────
log_placement = true            # new deposit placed
log_discovery = true            # ON_DISCOVERY / ON_PROSPECT reveal triggered
log_depletion = true            # chunk fully extracted, OreData wiped
log_replenish_actions = false   # very noisy — per-(deposit, chunk) replenish lines
log_scan_summary = true         # one-line summary per prospect-scan job
log_scan_rejections = false     # per-chunk diagnostic for failed deposit-type matches
log_lifecycle = true            # picker install, types loaded, queue drain

Client UI

config/coedeposits-client.toml:

# Show the toggle widget on Xaero's world map. Disable if it overlaps
# another mod's UI (e.g. Create: Steam 'n' Rails' Train Routes button).
# The Options → Controls keybind still works either way.
map_button_enabled = true
map_button_x_offset = 21
map_button_y_offset = 5
map_button_anchor = "LEFT"      # LEFT or RIGHT — which edge the widget anchors to

# Client-cache sync packets log ("cache: +N → total M"). Noisy — off by default.
log_client_sync = false

Compatibility

Third-party COE veins coexist — recipes you don't declare in deposits.json spawn via vanilla COE behaviour when a placement: "coe" entry exists; otherwise they're suppressed in enabled dimensions.
JEI / Jade — drilling recipes appear in the Drilling category and in-world tooltips.
Create: Steam 'n' Rails — no conflict. Both mods place a map widget though; coedeposits-client.toml lets you move/disable ours.
c2me — works. The picker runs on the chunk's worker thread. (Avoid the Fabric+Connector port with Lootr — use native NeoForge c2me.)

Pattern sharing

Generation is deterministic on (depositSeed, chunkX, chunkZ) + biome + distance-from-spawn:

# In world A:
/coedeposits seed
  → deposit seed: 4823651729 (world seed) | dim: minecraft:overworld

# In world B with the same deposits.json:
/coedeposits regenerate 4823651729
  → regenerated: placed 47 new in 2000-block radius
  → deposit seed is now 4823651729

Same seed + same deposits.json + similar biome layout → same pattern. The seed is per-dimension and persisted in SavedData.
