详细描述

Subclasses of QAbstractClipAnimator can be aggregated by a QEntity to provide animation capabilities. The animator components provide an interface for controlling the animation (e.g. start, stop). Each animator type requires some form of animation data such as a QAbstractAnimationClip as well as a QChannelMapper which describes how the channels in the animation clip should be mapped onto the properties of the objects you wish to animate.

The following subclasses are available:

• Qt3DAnimation::QClipAnimator
• Qt3DAnimation::QBlendedClipAnimator

enum QAbstractClipAnimator:: Loops

Holds the number of times the animation should play.

常量	值	描述
Qt3DAnimation::QAbstractClipAnimator::Infinite	-1	This will repeat the loop continuously until it is explicitly stopped.

channelMapper : Qt3DAnimation::QChannelMapper *

This property holds the ChannelMapper that controls how the channels in the animation clip map onto the properties of the target objects.

访问函数：

Qt3DAnimation::QChannelMapper *	channelMapper () const
void	setChannelMapper (Qt3DAnimation::QChannelMapper * channelMapper )

通知程序信号：

void	channelMapperChanged (Qt3DAnimation::QChannelMapper * channelMapper )

clock : Qt3DAnimation::QClock *

The clock controls the speed with which an animation is played.

访问函数：

Qt3DAnimation::QClock *	clock () const
void	setClock (Qt3DAnimation::QClock * clock )

通知程序信号：

void	clockChanged (Qt3DAnimation::QClock * clock )

loops : int

Holds the number of times the animation should play.

The value is 1 by default: the animation will be played once and then stop.

若设为 QAbstractClipAnimator::Infinite , the animation will continuously repeat until it is explicitly stopped.

访问函数：

int	loopCount () const
void	setLoopCount (int loops )

通知程序信号：

void	loopCountChanged (int loops )

normalizedTime : float

This property holds the clips normalized time.

访问函数：

float	normalizedTime () const
void	setNormalizedTime (float timeFraction )

通知程序信号：

void	normalizedTimeChanged (float index )

running : bool

This property holds a boolean indicating whether the animation is currently running.

访问函数：

bool	isRunning () const
void	setRunning (bool running )

通知程序信号：

void	runningChanged (bool running )

成员函数文档编制

[slot] void QAbstractClipAnimator:: start ()

Starts the animation.

[slot] void QAbstractClipAnimator:: stop ()

Stops the animation.

bool QAbstractClipAnimator:: isRunning () const

Returns a boolean indicating whether the animation is currently running.

注意： Getter 函数对于特性 running .

int QAbstractClipAnimator:: loopCount () const

Returns the number of times the animation should play.

The value is 1 by default: the animation will play through once and then stop.

若设为 QAbstractClipAnimator::Infinite , the animation will continuously repeat until it is explicitly stopped.

注意： Getter 函数对于特性 loops .
