Triggers

This is an old version of this page. You can view the most recent version or browse the history.

Triggers are used to determine how a skill is triggered from within the mobs skill configuration section.

TRIGGERS CANNOT BE USED IN META-SKILLS AND SHOULD NOT BE INCLUDED IN THEM. Triggers can only be used to activate the meta-skill itself.

Table of all available triggers:

Trigger	When it fires...
onCombat	Default
onAttack	When the mob hits something
onDamaged	When the mob is damaged
onSpawn	When the mob spawns
onDespawn	When the mob is despawned
onReady	Triggered the first time a mob is spawned from a spawner
onLoad	When the mob is loaded (spawning or loading after a restart)
onDeath	When the mob dies
onTimer:#	Every # ticks (where # is the interval in ticks)
onInteract	When the mob is right-clicked
onPlayerKill	When the mob kills a player
onEnterCombat	When the mob enters combat (requires threat tables be on)
onDropCombat	When the mob leaves combat (requires threat tables be on)
onChangeTarget	When the mob changes targets (requires threat tables be on)
onExplode	When the mob explodes (typically only used for creepers)
onPrime	When the creeper charges up for an explosion
onCreeperCharge	When the creeper is charged (when lightning hits a creeper)
onTeleport	When the mob teleports (typically only used for endermen)
onSignal:[signal]	When the mob receives a signal
onShoot	When the mob fires a projectile
onTame	When the mob gets tamed
onBreed	When the mob breeds with another mob.
onTrade	When the Villager completes a trade. Requires Paper

Using Triggers

Triggers are defined in the skill section of the mob configuration and must use a tilde (~) in front of them. In the case of the Timer, a time in ticks is also required.

SkeletalWizard_Fire:
  Type: WITHER_SKELETON
  Display: '&Skeletal Fire Wizard'
  Health: 50
  Damage: 0.5
  Skills:
  - ignite{ticks=100} @target ~onAttack
  - skill{s=FireShield} @trigger ~onDamaged 0.1
  - skill{s=AOEFire} ~onTimer:300

In this example the mob will also set its target on fire when melee-attacking, will use a "FireShield" skill when taking damage, and will use the "AOEFire" skill every 300 ticks, or every 15 seconds.

Not using Triggers...

Skill triggers give far more flexibility in determining exactly when a skill should go off. It is highly recommended that you trigger all your skills using advanced triggers as opposed to the old, legacy methods.

If a skill does not have a trigger, it will default to the ~onCombat trigger which will execute when these events occur:

When the mob deals or takes damage
When the mob spawns
When the mob dies

SkeletalWarrior:
  Mobtype: skeleton
  Display: '<blue>A Skeletal Warrior</blue>'
  Skills:
  - skill{s=Bash} =10%-90%

In this instance the Bash skill is triggered when the mob deals or takes damage when it is between 10% and 90% health.

The @trigger Targeter

You may have noticed there is an @trigger targeter in the examples shown above, and listed in the targeters section. The @trigger will target the entity that "caused" the skill to trigger, i.e. when a player damages a mob and that mob has an ~onDamaged skill, it will target that player. If a signal is being sent to a mob, it will target the mob that sent the signal, and so on.

All Available Triggers

~onSpawn

Executes the skill when the mob spawns. This does not have @trigger.

EXAMPLE_MOB:
  Type: CHICKEN
  Skills:
    # sends a message to all the players in the world
    # when the mob spawns
    - message{m=SPAWN} @World ~onSpawn

~onDeath

Executes the skill when the mob dies. The entity that killed the mob is the @trigger.

EXAMPLE_MOB:
  Type: CHICKEN
  Skills:
    # sends a message to all the players in the world
    # when the mob dies
    - message{m=DEATH} @World ~onDeath

~onAttack

Executes the skill when the mob attacks an entity. The @trigger is the entity that took damage from the attack.

EXAMPLE_MOB:
  Type: CHICKEN
  Damage: 1
  Skills:
    # sends a message to all the players in the world
    # when the mob attacks an entity
    - message{m=ATTACK} @World ~onAttack

~onDamaged

Executes the skill when the mob takes damage. The @trigger is the attacker.

EXAMPLE_MOB:
  Type: CHICKEN
  Skills:
    # sends a message to all the players in the world
    # when the mob takes damage
    - message{m=DAMAGED} @World ~onDamaged

~onDespawn

Executes the skill when the mob despawns.

EXAMPLE_MOB:
  Type: CHICKEN
  Skills:
    # sends a message to all the players in the world
    # when the mob takes damage
    - message{m=DESPAWNED} @World ~onDespawn

~onExplode

Executes the skill when the mob explodes. mobGriefing gamerule must be set to true for this to work. Generally, this trigger only works with creepers and TNTs since other mobs tend to not explode...

EXAMPLE_MOB:
  Type: CREEPER

    # sends a message to all the players in the world
    # when the mob explodes
    - message{m=EXPLODE} @World ~onExplode

~onTimer:[tick(s)]

Executes the skill every n^th ticks. Ticks can't be zero and 20 ticks is equal to 1 second. Care must be taken when using this trigger as it can lead to server/client performance issues. i.e. large amounts of particle effects can cause client lag, or can kick the client from the server

EXAMPLE_MOB:
  Type: CHICKEN
  Skills:
    # sends a message to all the players in the world every 0.05 seconds
    - message{m=TIMER every tick (0.05 seconds)} @World ~onTimer:1
