Blocks

You can also create custom ores/blocks with their custom drops! The config file is blocks.yml

blocks.yml

ruby_ore:
  enabled: true
  permission: ruby_ore
  model_id: 14
  name: '&fRuby Ore'
  specific_properties:
    light_level: 15
    break_tools_blacklist:
      - WOODEN_PICKAXE
      - STONE_PICKAXE
    break_tools_whitelist:
      - PICKAXE

      max_height: 16
      amount: 6
      iterations: 3
    cancel_drop: true

Here you can see the ruby_ore spawned under the world (I'm using X-Ray to see them)
