Custom Generators

A classic skyblock cobble generator only ever gives you cobblestone. IgniteSky's generator turns that same lava and water contact into a real progression sink: the block that forms is rolled from a weighted table that gets richer as the island upgrades.

How it works

Whenever lava meets water on an island and a block would normally form, IgniteSky replaces it with a weighted random block from the island's current generator tier. Each tier is a list of blocks with weights, so a higher number means that block comes out more often.

An island's tier is its generator upgrade level (see Upgrades & Limits), so players climb tiers by buying that upgrade through /is upgrades. Tier 0 is the first entry below.

generator:
  enabled: true
  # Which vanilla formed blocks the generator intercepts. Others (e.g. obsidian) are left vanilla.
  # Omit to use the default cobblestone / stone / basalt.
  sources:
    - COBBLESTONE
    - STONE
    - BASALT
  tiers:
    - name: Basic
      display: "<gray>Basic Generator"   # MiniMessage label for menus / placeholders
      fallback: COBBLESTONE              # produced if the table is empty/misconfigured
      blocks:
        COBBLESTONE: 80
        COAL_ORE: 15
        IRON_ORE: 5
    - name: Reinforced
      blocks:
        COBBLESTONE: 55
        COAL_ORE: 18
        IRON_ORE: 18
        GOLD_ORE: 6
        REDSTONE_ORE: 3
    - name: Advanced
      blocks:
        COBBLESTONE: 30
        IRON_ORE: 25
        GOLD_ORE: 20
        REDSTONE_ORE: 12
        LAPIS_ORE: 8
        DIAMOND_ORE: 5
    - name: Elite
      blocks:
        IRON_ORE: 25
        GOLD_ORE: 25
        REDSTONE_ORE: 15
        DIAMOND_ORE: 20
        EMERALD_ORE: 15

The weights are relative, so they do not have to add up to 100. A block listed with weight 25 against a total of 100 simply forms a quarter of the time. Material names follow Bukkit's enum.

Two extra per-tier knobs: display is a MiniMessage label used wherever the tier is shown, and fallback is the block produced if a tier's table is empty or misconfigured (defaults to cobblestone). The top-level sources list controls which vanilla blocks the generator intercepts in the first place, so you can, for example, also catch stone-generator output or leave basalt vanilla.
