Class KeyFrameTransform

java.lang.Object

com.bonzaiengine.animation.KeyFrame<Transform>

com.bonzaiengine.animation.KeyFrameTransform

All Implemented Interfaces:

java.lang.Cloneable, java.lang.Iterable<KeyData<Transform>>

public final class KeyFrameTransform
extends KeyFrame<Transform>

An optimized implementation for

KeyFrame

which is approximately 25% smaller in term of memory usage.
Usefull to reduce animation memory usage, which is important for skinning animation
