upgrades.yml

upgrades.yml defines every upgrade, its tiers, and what each tier costs. Add, remove, or retune tiers freely — the Upgrades menu is built from this file automatically.

For the default tier tables in friendly form, see Upgrades and Generators.

Two Upgrade Types

type	Meaning
value	The level holds a single number — a limit, multiplier, or size
generator	The level holds weighted block chances

A value Upgrade

upgrades:
  team-limit:
    display-name: "&eTeam Limit"
    icon: PLAYER_HEAD
    slot: 10
    type: value
    levels:
      1: { value: 4,  required-level: 0,  required-money: 0 }
      2: { value: 6,  required-level: 5,  required-money: 5000 }
      3: { value: 8,  required-level: 12, required-money: 15000 }
      4: { value: 12, required-level: 25, required-money: 40000 }

Field	Meaning
display-name	Item name in the menu
icon	Item material
slot	Menu slot
type	value
levels.<n>.value	The number this tier sets
required-level	Island level needed
required-money	Vault cost (ignored when economy is off)

What value means depends on the upgrade:

Upgrade	value is...
team-limit	Max members
size	Island size in blocks (protection radius = value/2)
crop-growth	% chance to double a crop
mob-drops	Drop multiplier
spawner-rates	Spawner delay multiplier (lower = faster)

A generator Upgrade

generator:
  display-name: "&7Generator"
  icon: COBBLESTONE
  slot: 24
  type: generator
  levels:
    1:
      required-level: 0
      required-money: 0
      chances:
        COBBLESTONE: 100
    2:
      required-level: 6
      required-money: 8000
      chances:
        COBBLESTONE: 80
        COAL_ORE: 15
        IRON_ORE: 5

chances are weights — a block is rolled in proportion to its weight when the generator forms. See Generators.

Adding Your Own Tier

Just append a new numbered level:

    5: { value: 16, required-level: 60, required-money: 200000 }

The menu picks it up automatically. Run /is admin reload to apply.
