Detailed Description

Bus that defines the interface for flipbook animations.

A flipbook animation component exists on an entity that has an image component and interacts with the image bus to achieve its functionality (such as by manipulating sprite-sheet indices).

Member Enumeration Documentation

enum UiFlipbookAnimationInterface::FramerateUnits

strong

Units of speed for framerate.

Enumerator
FPS	Framerate of animation.
SecondsPerFrame	Number of seconds to wait before playing next frame.

enum UiFlipbookAnimationInterface::LoopType

strong

Defines the looping behavior when playing back a flipbook animation.

Enumerator
None	No looping behavior.
Linear	When end frame is reached, next frame will be the loop start frame.
PingPong	When end frame is reached, next frame will be the previous frame, continuing in reverse until the start frame is reached.

Member Function Documentation

virtual AZ::u32 UiFlipbookAnimationInterface::GetCurrentFrame ( )

pure virtual

Returns

The current frame of the animation that's being rendered.

virtual AZ::u32 UiFlipbookAnimationInterface::GetEndFrame ( )

pure virtual

Returns

End frame of the animation.

virtual float UiFlipbookAnimationInterface::GetFramerate ( )

pure virtual

Gets the speed used to determine when to transition to the next frame.

Framerate is defined relative to unit of time, specified by FramerateUnits.

See GetFramerateUnit, SetFramerateUnit.

virtual AZ::u32 UiFlipbookAnimationInterface::GetLoopStartFrame ( )

pure virtual

This frame is distinct from the start frame and allows a "lead in" seqence of frames to play leading up to the looping animation. The frames that occur prior to the loop start frame will only play once.

Returns

The frame to start the loop from.

virtual LoopType UiFlipbookAnimationInterface::GetLoopType ( )

pure virtual

Returns

The LoopType of the flipbook animation.

virtual AZ::u32 UiFlipbookAnimationInterface::GetStartFrame ( )

pure virtual

Returns

The starting frame of the animation.

virtual bool UiFlipbookAnimationInterface::IsPlaying ( )

pure virtual

Returns

True if the flipbook animation is currently playing, false otherwise.

virtual void UiFlipbookAnimationInterface::SetCurrentFrame ( AZ::u32  currentFrame )

pure virtual

Sets the current frame of the animation to render.

If the animation is currently playing, this will effectively "skip" to the given frame.

virtual void UiFlipbookAnimationInterface::SetFramerate ( float  framerate )

pure virtual

Sets the speed used to determine when to transition to the next frame.

Framerate is defined relative to unit of time, specified by FramerateUnits.

See GetFramerateUnit, SetFramerateUnit.

virtual void UiFlipbookAnimationInterface::SetIsAutoPlay ( bool  isAutoPlay )

pure virtual

Sets whether the animation will automatically begin playing.

This flag is ignored after the component has activated.

virtual void UiFlipbookAnimationInterface::Start ( )

pure virtual

Start the animation sequence, beginning at the start frame.

If a LoopType other than None has been set, the animation won't stop unless explicitly done so (or the image is unloaded/destroyed).
