Goal 5.46.0

abstract class · pocketmine\entity\ai\goal\Goal · source

A behaviour of a mob (wander, panic, attack...). Goals are run by a GoalSelector: a goal starts when Goal::canStart() returns true and no running goal with a higher priority holds any of its control flags, and stops when Goal::canContinue() returns false or a more important goal needs one of its flags.

Constants

FLAG_JUMP

public const FLAG_JUMP = 4

The goal makes the mob jump.

FLAG_LOOK

public const FLAG_LOOK = 2

The goal turns the mob's head (look control).

FLAG_MOVE

public const FLAG_MOVE = 1

The goal moves the mob (pathfinding, move control).

FLAG_TARGET

public const FLAG_TARGET = 8

The goal selects the mob's attack target.

Methods

canContinue()

public function canContinue() : bool

Returns whether the running goal should keep running. Called every AI tick.

canStart()

Returns whether the goal should start now. Called only every few ticks (see GoalSelector), so it may do moderately expensive checks.

getFlags()

public function getFlags() : int

Returns a bitmask of the FLAG_* constants this goal needs exclusively while it runs.

isInterruptible()

public function isInterruptible() : bool

Returns whether a goal with a higher priority may stop this goal to take its flags.

public function start() : void

stop()

public function stop() : void

tick()
