Class AbstractTween

java.lang.Object

com.simsilica.lemur.anim.AbstractTween

All Implemented Interfaces:

Tween

public abstract class AbstractTween
extends java.lang.Object
implements Tween

Base implementation of the Tween interface that provides default implementations of the getLength() and interopolate() methods that provide common tween clamping and bounds checking. Subclasses need only override the doInterpolate() method and the rest is handled for them.

Modifier and Type	Method and Description
protected abstract void	doInterpolate(double t)
double	getLength() Returns the length of the tween.
boolean	interpolate(double t) Default implementation clamps the time value, converts it to 0 to 1.0 based on getLength(), and calls doInterpolate().

Method Detail

getLength

public double getLength()

Description copied from interface: Tween

Returns the length of the tween. If 't' represents time in seconds then this is the notional time in seconds that the tween will run. Note: all of the caveats are because tweens may be externally scaled in such a way that 't' no longer represents actual time.

Specified by:

getLength in interface Tween

interpolate

public boolean interpolate(double t)

Default implementation clamps the time value, converts it to 0 to 1.0 based on getLength(), and calls doInterpolate().

Specified by:

doInterpolate
