Detailed Description

Non-visual entities in the QML item tree that define behavior for their parent Actor.

Logics are initialized in the first Engine::LOGICS_PHASE and are then evaluated through a call to update() on each subsequent Engine::LOGICS_PHASE.

Constructor & Destructor Documentation

Logic::Logic ( QObject * parent = nullptr )

inlineexplicit

Constructs a Logic.

Parameters

parent Parent object

Member Function Documentation

void Logic::activeChanged ( )

signal

Emitted when active changes.

Actor* Logic::getActor ( ) const

inline

Returns actor.

virtual void Logic::init ( )

virtual

Performs initialization of this Logic.

Note: This function can be called more than once if the Logic exists in the game outside of the Level and the Level is changed / re-loaded.

Reimplemented in EmitterLogic, InterpolationLogic, CameraMovementLogic, MagneticAttractorLogic, PickupLogic, ContactTrigger, WaterBodyLogic, AcceleratorLogic, JavaScriptLogic, and GameInputLogic.

bool Logic::isActive ( ) const

inline

Returns active.

void Logic::setActive ( bool value )

Sets active.

Parameters

value Boolean to set active to

virtual void Logic::update ( )

virtual

Performs the update (i.e. execution of behavior) of this Logic.

Note: This method is only executed by Engine in Engine::LOGICS_PHASE if active is true.

Reimplemented in EmitterLogic, InterpolationLogic, RollingMovementLogic, CameraMovementLogic, MagneticAttractorLogic, ParticleEmitterLogic, ActorEmitterLogic, MagneticHighlightLogic, WaterBodyLogic, AcceleratorLogic, StopwatchLogic, GameInputLogic, JavaScriptLogic, and Trigger.

Property Documentation

bool Logic::active

readwrite

Whether or not Engine calls update() on this Logic during the Engine::LOGICS_PHASE.

Actor Logic::actor

read
