详细描述

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 值。

注意： that the animation controller doesn't have internal timer, but instead the user is responsible for updating the position property in timely manner.

特性文档编制

activeAnimationGroup : int

Holds the currectly active animation group.

访问函数：

int	activeAnimationGroup () const
void	setActiveAnimationGroup (int index )

通知程序信号：

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.

访问函数：

Qt3DCore::QEntity *	entity () const
void	setEntity (Qt3DCore::QEntity * entity )

通知程序信号：

void	entityChanged (Qt3DCore::QEntity * entity )

位置 : 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.

访问函数：

float	位置 () const
void	setPosition (float position )

通知程序信号：

void	positionChanged (float position )

positionOffset : float

Holds the position offset of the animation.

访问函数：

float	positionOffset () const
void	setPositionOffset (float offset )

通知程序信号：

void	positionOffsetChanged (float offset )

positionScale : float

Holds the position scale of the animation.

访问函数：

float	positionScale () const
void	setPositionScale (float scale )

通知程序信号：

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.

访问函数：

bool	recursive () const
void	setRecursive (bool recursive )

通知程序信号：

void	recursiveChanged (bool recursive )

QAnimationController:: QAnimationController ( QObject * parent = nullptr)

Constructs a new QAnimationController with parent .

void QAnimationController:: addAnimationGroup ( Qt3DAnimation::QAnimationGroup * animationGroup )

添加给定 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
