Detailed Description

Representation of an entity within the Game scene.

Actors are owned by a Level, and are composed of Logics, Graphics, and optionally a Body. An Actor mediates communication between these three components, with each component defining gameplay, visuals, and physics for this Actor respectively. The Actor class is not intended to be subclassed directly. Instead, it is "templated" into QML components defined in QML files (for example, Orb in Orb.qml). This template defines the Actor's default components and setup, and how they are connected. The template in turn can be specialized by the Level in a level file which overrides these defaults (for example setting the initial position of that instance of the Actor).

Member Enumeration Documentation

Different categories of Actors, used to differentiate among them.

See also
actorType
Enumerator
GenericActor 

Actor which is not any other type.

PlayerActor 

Actor which is controlled by a player (a user).

This can be used, for example, to control Camera focus (CameraMovementLogic).

Constructor & Destructor Documentation

Actor::Actor ( )

Constructs an Actor.

Member Function Documentation

void Actor::actorTypeChanged ( )
signal

Emitted when actorType changes.

virtual void Actor::componentComplete ( )
overrideprotectedvirtual

Performs additional initialization, like finding this Actor's associated Body, if one exists.

Reimplemented from QQuickItem.

Q_INVOKABLE QObject* Actor::findChildByTypeName ( const QString typeName)

Look through our subtree and find a child which is of the type, or a subtype of the type named by string.

For example, "ParticleEmitterLogic" finds a child of type ParticleEmitterLogic.

Parameters
typeNameName of the type to look for
ActorType Actor::getActorType ( ) const
inline

Returns actorType.

Body* Actor::getBody ( ) const

Returns body.

void Actor::setActorType ( ActorType  actorType)

Sets actorType.

Parameters
actorTypeActorType to set actorType to

Property Documentation

ActorType Actor::actorType
readwrite

Type of this Actor, as one of ActorType.

This property is used to differentiate categories of Actors, as Actors are not generally proper C++ subclasses of Actor, and thus have no differentiating type information.

Body Actor::body
read

Associated physics Body, if it exists.
