Events

The (...) brackets contain the type of the variables or targets.

The following variables always exist, no matter the event:

  • mana_cost (double): Contains the set mana cost of a spell.
  • min_block_height (int): The minimum block height of the dimension.
  • max_block_height (int): The maximum block height of the dimension.

Hook events

These events hook into other mechanics of the game like when a player takes damage.

They contain the following target for equipped spells:

  • owner (player): The player that has the spell equipped.

They contain the following target for delayed spells:

  • holder (player): The player that holds this delayed spell.

Cancelable events

Some events are cancelable and they contain the following variable:

  • event_is_canceled (boolean): Determines if this event was canceled already by any mod or spell. The end result of this variable will determine if the event is fully canceled or not. It is not advisable to ever un-cancel an event that was already canceled (i.e. to set this variable to false after it was true).

active activation

When the spell in a spell slot of a player is fired by pressing the key bind or when a cast is forced via command.

Target groups:

  • owner (player): The player that has this spell equipped.

Variables:

  • spell_slot (int): The integer representing the slot the spell was in starting at 0. If the spell was cast via command, then this value is -1.

on_equip activation

When a spell is equipped into a spell slot of a player (eg. when equipping a spell in the spell progression menu).

Target groups:

  • owner (player): The player that has equipped this spell.

Variables:

  • spell_slot (int): The integer representing the slot the spell was equipped in starting at 0.

on_unequip activation

Target groups:

  • victim (living_entity): The entity that is taking the damage.

Variables:

  • damage_type (String): The type of damage.
