Class Keyframe

java.lang.Object
  com.jme.animation.Keyframe

All Implemented Interfaces:

Savable

public class Keyframe
extends java.lang.Object
implements Savable

Keyframe defines a positional or a rotational keyframe. The keyframe defines a position a vertex should be at a given time. An animation system uses a collection of these keyframes to build a sequence of transitions to manipulate and animate a collection of vertices.

Field Detail

time

public float time

The time in milliseconds after the start of the animation for which that keyframe occurs.

x

public float x

For a position keyframe (x,y,z) are the coordinates to translate. For a rotation keyframe (x,y,z) are angles, in radians, to rotate.

y

public float y

For a position keyframe (x,y,z) are the coordinates to translate. For a rotation keyframe (x,y,z) are angles, in radians, to rotate.

z

public float z

For a position keyframe (x,y,z) are the coordinates to translate. For a rotation keyframe (x,y,z) are angles, in radians, to rotate.

Constructor Detail

Keyframe

public Keyframe(float time,
                float x,
                float y,
                float z)

Create a keyframe at a given time and vector.

Parameters:

time - the time in milliseconds after the start of the animation for which that keyframe occurs.

x - the x value of the translation or rotation for the keyframe.

y - the y value of the translation or rotation for the keyframe.

z - the z value of the translation or rotation for the keyframe.

Method Detail

write

public void write(JMEExporter e)
           throws java.io.IOException

getClassTag

public java.lang.Class getClassTag()

Description copied from interface: Savable

The peristed type for the object. Note that tag here does not mean XML tag, but the class that the object is tagged with.
