Drop Tables

Drop tables

Drop tables decide what a mob drops when it dies. They live in droptables/ (and each pack's DropTables/), nested folders are fine.

nm_bison_drops:
  MinItems: 2
  MaxItems: 3
  Drops:
  - EXP 5-11 100%
  - LEATHER 4-5 80%
  - nm_bison_fur 2-3 40%

Fields

Field	Default	Description
Drops	-	The drop lines, see below. Required
MinItems	0	At least this many item entries drop
MaxItems	no limit	At most this many item entries drop

A file can hold several tables, every top-level key with a Drops: list is one table.

Drop lines

<what> <amount> <chance>

Part	Examples	Notes
what	BONE, nm_bison_fur, nm_other_table, EXP	See the order below
amount	3, 2-4	Optional, default 1. A range is rolled between both numbers
chance	80%, 0.8, 1	Optional, default 100%

A line like BONE 25% is read as a chance, BONE 3 as an amount.

What a name means, checked in this order:

1. EXP, experience or xp: experience points
2. The name of another drop table (it is rolled as many times as the amount says)
3. A registered item
4. A Vanilla material

Anything else is logged once and skipped.

How a roll works

1. Every line is rolled against its chance.
2. EXP lines are added up separately. They do not count towards MinItems/MaxItems.
3. If more item entries hit than MaxItems, random ones are dropped. If fewer than MinItems hit, random missed ones are added (without rolling their chance again).
4. Item amounts above the stack size are split into several stacks.

Using a table on a mob

In the mob file, Drops: lists tables and/or direct drops:

nm_bison:
  Type: IRON_GOLEM
  Options:
    PreventOtherDrops: true
  Drops:
  - nm_bison_drops
  - DIAMOND 1 5%

As soon as a mob has a Drops: list, its vanilla drops and vanilla experience are removed, so only what you define drops. PreventOtherDrops: true does the same for mobs that have no Drops:.

/bettermob reload reloads the tables. Tables referencing each other in a loop stop after 5 levels.
