Detailed Description

Series of animations as a single animation.

It's often useful to put together a series of animations into a sequence. This class manages a series of animations objects and runs them as one big animation. You can even add animation sequences to other animation sequences to build up complex sequences.

You can skip the current sub-animation, you can restart to the beginning of the sequence, or you can stop the entire thing.

Member Typedef Documentation

AnimationArray

using AnimationArray = std::vector<std::shared_ptr<detail::AnimationBase> >

protected

Helper type for an array of animations.

Constructor & Destructor Documentation

AnimationSequence()

AnimationSequence ( bool  loop = false )

inlineexplicitnoexcept

Parameters

loop	Should the animation sequence loop.

Member Function Documentation

add() [1/3]

virtual void add ( const std::shared_ptr< detail::AnimationBase > &  animation )

inlinevirtual

Add a sub animation to the sequence.

Parameters

animation

The animation.

add() [2/3]

void add ( const std::shared_ptr< T > &  animation )

inline

Add an animation to the animation sequence.

This will take a reference to the shared_ptr and manage the lifetime of the animation.

Parameters

animation

The animation.

add() [3/3]

virtual void add ( detail::AnimationBase &  animation )

inlinevirtual

Add an animation to the animation sequence.

Parameters

animation

The animation.

next()

bool next ( )

inlineoverridevirtual

Periodic call to the animation.

This must be called until it returns false. When it returns false, the animation is done.

Implements AnimationBase.

remove()

void remove ( detail::AnimationBase *  animation )

inline

Remove the first occurence of a sub animation from the sequence.

Parameters

animation

The animation.

removeAt()

void removeAt ( size_t  pos )

inline

Remove the sub animation at the given position from the sequence.

Parameters

pos	Position of the sub animation to remove. pos starts from 0.

removeLast()

void removeLast ( )

inline

Remove the last sub animation from the sequence.

resume()

void resume ( )

inlineoverridevirtual

Resume the animation.

Implements AnimationBase.

skip()

bool skip ( )

inline

Skip to the next sub animation in the sequence.

start()

void start ( )

inlineoverridevirtual

Start the animation.

Implements AnimationBase.

stop()

void stop ( )

inlineoverridevirtual

Stop the animation.

Implements AnimationBase.

The animations of the sequence.

m_current

size_t m_current {0}

protected

Index of the current animation.

m_loop

bool m_loop {false}

protected

Should the animation sequence loop?
