public class RelativeWanderBehavior
extends SimpleWanderBehavior

Wander is a type of random steering. This behavior retain steering direction state and make small random displacements to it each frame. Thus at one frame the character may be turning up and to the right, and on the next frame will still be turning in almost the same direction.

Constructor Detail

RelativeWanderBehavior

public RelativeWanderBehavior(Agent agent,
                      float rX,
                      float rY,
                      float rZ,
                      float relativeFactor)

Parameters:

relativeFactor - How much should differ each new wander force ? A value near to 0 means that each new force must differ slightly from the previous one. 1 means that the behaviour will work as a simple wander behavior

Throws:

SteeringExceptions.IllegalIntervalException - If relative factor is not contained in the [0, 1] interval.

Method Detail

changeSteer

protected void changeSteer(float tpf)

Description copied from class: SimpleWanderBehavior

Metod for changing the steer force.

Overrides:

changeSteer in class SimpleWanderBehavior

Parameters:

tpf - time per frame

See Also:

SimpleWanderBehavior.changeSteer(float)

setRelativeFactor

public void setRelativeFactor(float factor)

Parameters:

relativeFactor - How much should differ each new wander force ? A value near to 0 means that each new force must differ slightly from the previous one. 1 means that the behaviour will work as a simple wander behavior

Throws:

SteeringExceptions.IllegalIntervalException - If relative factor is not contained in the [0, 1] interval.

getRelativeFactor

public float getRelativeFactor()

Returns:

relativeFactor How much differ each new wander force. A value near to 0 means that each new force differ slightly from the previous one. 1 means that the behaviour works as a simple wander behavior.
