All Implemented Interfaces:

com.jme3.export.Savable, com.jme3.scene.control.Control

Direct Known Subclasses:

RelativeWanderBehavior

public class SimpleWanderBehavior
extends AbstractWanderBehavior

This behavior is based on a easy implementation that "generates random steering force each frame, but this produces rather uninteresting motion. It is 'twitchy' and produces no sustained turns.

Steer forces changes durring time.

Method Detail

calculateRawSteering

protected com.jme3.math.Vector3f calculateRawSteering()

Calculate steering vector.

Specified by:

calculateRawSteering in class AbstractStrengthSteeringBehavior

Returns:

steering vector

See Also:

AbstractSteeringBehavior.calculateSteering()

changeSteer

protected void changeSteer(float tpf)

Metod for changing the steer force.

Parameters:

tpf - time per frame

newRandomSteer

protected com.jme3.math.Vector3f newRandomSteer()

Returns:

A new random steer force

setMaxRandSteer

public void setMaxRandSteer(float rX,
                   float rY,
                   float rZ)

Setting random steer

Parameters:

rX - max x-random steer

rY - max y-random steer

rZ - max z-random steer

setConstantMod

public void setConstantMod(float value)

The generated steer module will be a constant value. If the distance is 0 or lower, there will be no constant steer module.

Parameters:

distance - Target-Agent distance

getHasConstantMod

public boolean getHasConstantMod()

Returns:

If the generated steer module is a constant value.
