[Version 4.10] Presets

A preset is a way to set some specific properties to a single mob (E.g. it lets you make a boss zombie that rarely spawns).

In the config folder you'll find a presets folder, in here you want to add your presets. A preset is a Mob property file without the target and presets keys.

But also has this bonus properties:

• boss_bar: (Boss Bar Object)

Once you've created you preset you must add the preset to the mob with the presets key.
In the mob file under the presets.list key you'll have to add a Weighted preset.

NOTE

Presets by default are exclusive to the mob (so other properties in the mob file will not be applied) unless the presets.mode is changed.

Preset

• mode: (String) How will the preset behave with the other properties in the file.
  "exclusive": when the preset is chosen the other properties will not apply. This is the default behaviour
  "before": the preset properties are applied before the mob properties. "after": the preset properties are applied after the mob properties.
• chance: (Modifiable Value Object) percentage chance (between 0 and 1) for mob to get a preset applied
• list: a (Weighted Presets) list

Weighted Preset

• id: (Resource location) The preset id (the preset file with the namespace and without the .json at end)
• weight: (Modifiable Value Object) The weight of the preset. Can be omitted and will default to 1
• chance: (Modifiable Value Object) rapresenting the percentage chance (between 0 and 1) to apply the preset. If omitted the preset will always be applied.
• conditions: (Conditions Object)

Example

This examples shows how to make a "ghost" mob (an invisible silent zombie with glowing effect) that has 5% chance to spawn only above sea level.
