Detailed Description
Qt3DAnimation::QAnimationController class controls the selection and playback of animations. The class can be used to find all animations from Qt3DCore::QEntity tree and create QAnimationGroups from the animations with the same name. The user can select which animation group is currently controlled with the animation controller by setting the active animation. The animation position is then propagated to that group after scaling and offsetting the provided position value with the positionScale and positionOffset values.
Note: that the animation controller doesn't have internal timer, but instead the user is responsible for updating the position property in timely manner.
Property Documentation
activeAnimationGroup : int
Holds the currectly active animation group.
Access functions:
| int | activeAnimationGroup() const |
| void | setActiveAnimationGroup(int index) |
Notifier signal:
| void | activeAnimationGroupChanged(int index) |
entity : Qt3DCore::QEntity*
Holds the entity animations are gathered and grouped from. If the controller already holds animations, they are cleared.
Access functions:
| Qt3DCore::QEntity * | entity() const |
| void | setEntity(Qt3DCore::QEntity *entity) |
Notifier signal:
| void | entityChanged(Qt3DCore::QEntity *entity) |
position : float
Holds the current position of the animation. When the position is set, it is scaled and offset with positionScale/positionOffset and propagated to the active animation group.
Access functions:
| float | position() const |
| void | setPosition(float position) |
Notifier signal:
| void | positionChanged(float position) |
positionOffset : float
Holds the position offset of the animation.
Access functions:
| float | positionOffset() const |
| void | setPositionOffset(float offset) |
Notifier signal:
| void | positionOffsetChanged(float offset) |
positionScale : float
Holds the position scale of the animation.
Access functions:
| float | positionScale() const |
| void | setPositionScale(float scale) |
Notifier signal:
| void | positionScaleChanged(float scale) |
recursive : bool
Holds whether the recursively search the entity tree when gathering animations from the entity. If set to true, the animations are searched also from the child entities of the entity. If set to false, only the entity passed to the controller is searched.
Access functions:
| bool | recursive() const |
| void | setRecursive(bool recursive) |
Notifier signal:
| void | recursiveChanged(bool recursive) |
Member Function Documentation
QAnimationController::QAnimationController(QObject *parent = nullptr)
Constructs a new QAnimationController with parent.
void QAnimationController::addAnimationGroup(Qt3DAnimation::QAnimationGroup *animationGroup)
Adds the given animationGroup to the controller.
QVector<Qt3DAnimation::QAnimationGroup *> QAnimationController::animationGroupList()
Returns the list of animation groups the conroller is currently holding.
int QAnimationController::getAnimationIndex(const QString &name) const
Returns the index of the animation with name. Returns -1 if no AnimationGroup with the given name is found.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
Qt3DAnimation::QAnimationGroup *QAnimationController::getGroup(int index) const
Returns the AnimationGroup with the given index.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
void QAnimationController::removeAnimationGroup(Qt3DAnimation::QAnimationGroup *animationGroup)
Removes the given animationGroup from the controller.
void QAnimationController::setAnimationGroups(const QVector<Qt3DAnimation::QAnimationGroup *> &animationGroups)
Sets the animationGroups for the controller. Old groups are cleared.
