Class Evade<T extends com.badlogic.gdx.math.Vector<T>>

java.lang.Object

com.badlogic.gdx.ai.steer.SteeringBehavior<T>

com.badlogic.gdx.ai.steer.behaviors.Pursue<T>

com.badlogic.gdx.ai.steer.behaviors.Evade<T>

Type Parameters:

T - Type of vector, either 2D or 3D, implementing the Vector interface

public class Evade<T extends com.badlogic.gdx.math.Vector<T>>
extends Pursue<T>

Evade behavior is almost the same as Pursue except that the agent flees from the estimated future position of the pursuer. Indeed, reversing the acceleration is all we have to do.

Constructor Detail

Evade

public Evade(Steerable<T> owner,
             Steerable<T> target)

Creates a Evade behavior for the specified owner and target. Maximum prediction time defaults to 1 second.

Parameters:

owner - the owner of this behavior

target - the target of this behavior, typically a pursuer.

Evade

public Evade(Steerable<T> owner,
             Steerable<T> target,
             float maxPredictionTime)

Creates a Evade behavior for the specified owner and pursuer.

Parameters:

owner - the owner of this behavior

target - the target of this behavior, typically a pursuer

maxPredictionTime - the max time used to predict the pursuer's position assuming it continues to move with its current velocity.

Method Detail

getActualMaxLinearAcceleration

protected float getActualMaxLinearAcceleration()

Description copied from class: Pursue

Returns the actual linear acceleration to be applied. This method is overridden by the Evade behavior to invert the maximum linear acceleration in order to evade the target.

Overrides:

getActualMaxLinearAcceleration in class Pursue<T extends com.badlogic.gdx.math.Vector<T>>

setOwner

public Evade<T> setOwner(Steerable<T> owner)

Description copied from class: SteeringBehavior

Sets the owner of this steering behavior.

Overrides:

setOwner in class Pursue<T extends com.badlogic.gdx.math.Vector<T>>

Returns:

this behavior for chaining.

setEnabled

public Evade<T> setEnabled(boolean enabled)

Description copied from class: SteeringBehavior

Sets this steering behavior on/off.

Overrides:

setEnabled in class Pursue<T extends com.badlogic.gdx.math.Vector<T>>

Returns:

this behavior for chaining.

setLimiter

public Evade<T> setLimiter(Limiter limiter)

Sets the limiter of this steering behavior. The given limiter must at least take care of the maximum linear acceleration.

Overrides:

setLimiter in class Pursue<T extends com.badlogic.gdx.math.Vector<T>>

Returns:

this behavior for chaining.

setTarget

public Evade<T> setTarget(Steerable<T> target)

Description copied from class: Pursue

Sets the target.

Overrides:

setTarget in class Pursue<T extends com.badlogic.gdx.math.Vector<T>>

Returns:

this behavior for chaining.
