Want your survival world to be harder? SepdOrelimiter lets you control how common each ore is, using simple percentages.

Instead of fiddling with world generation files, you just look at your world's ore ratio and change it with a command.

How it works

1. See your world's ore ratio

/orechecker ratio

The plugin scans every generated chunk and shows each ore as a share of all ore, for example 20% diamond, 10% iron, 40% gold.

2. Change it

/orechecker set diamond 7

Now diamond is only 7% of all ore. The other ores automatically share the remaining 93%. You can set as many ores as you like.

3. Apply it to your existing world

/orechecker apply

Chunks that are already generated get updated too. New chunks are limited automatically as players explore.

Features

• Set the ratio of each ore in plain percent
• Works on the whole world, not just nearby chunks
• New chunks follow your ratio automatically
• Separate ratios for the Overworld and the Nether
• Runs a few chunks at a time, so it won't freeze your server
• Safe to re-apply if you change your mind later
• Supports tab completion for ores and worlds

Supported ores

• Overworld: coal, iron, copper, gold, redstone, lapis, diamond, emerald
• Nether: nether gold, quartz, ancient debris

(Normal and deepslate versions count together.)

Commands

Command	What it does
/orechecker ratio [world]	Show the ore percentages of a world
/orechecker set <ore> <percent> [world]	Set an ore's share
/orechecker apply [world]	Apply your ratio to existing chunks
/orechecker reset [world]	Remove your ratio plan
/orechecker stop	Stop a running scan or apply

Aliases: /oc, /sepdore Permission: sepdorelimiter.admin (ops by default)

Good to know

• It only removes ore, it never adds it. To reach your ratio, it thins out the other ores. Extra ore blocks are swapped for stone, deepslate or netherrack.
• Applying to existing chunks is permanent. Please back up your world before running /orechecker apply.
• Ore amounts differ by biome, so a newly explored area may drift slightly from your exact percentages. Run /orechecker ratio again to check.
• Your ratios are saved in data.yml inside the plugin folder.

Installation

1. Drop the jar into your server's plugins folder.
2. Restart the server.
3. Run /orechecker ratio in the world you want to change.

Works on Spigot and Paper 1.18 or newer (Java 17+).
