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

java.lang.Object

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

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

Type Parameters:

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

Direct Known Subclasses:

Flee

public class Seek<T extends com.badlogic.gdx.math.Vector<T>>
extends SteeringBehavior<T>

Seek behavior moves the owner towards the target position. Given a target, this behavior calculates the linear steering acceleration which will direct the agent towards the target as fast as possible.

Field Detail

target

protected Location<T extends com.badlogic.gdx.math.Vector<T>> target

The target to seek

Constructor Detail

Seek

public Seek(Steerable<T> owner)

Creates a Seek behavior for the specified owner.

Parameters:

owner - the owner of this behavior.

Seek

public Seek(Steerable<T> owner,
            Location<T> target)

Creates a Seek behavior for the specified owner and target.

Parameters:

owner - the owner of this behavior

target - the target agent of this behavior.

Method Detail

calculateRealSteering

protected SteeringAcceleration<T> calculateRealSteering(SteeringAcceleration<T> steering)

Description copied from class: SteeringBehavior

Calculates the steering acceleration produced by this behavior and writes it to the given steering output.

This method is called by SteeringBehavior.calculateSteering(SteeringAcceleration) when this steering behavior is enabled.

Specified by:

calculateRealSteering in class SteeringBehavior<T extends com.badlogic.gdx.math.Vector<T>>

Parameters:

steering - the steering acceleration to be calculated.

Returns:

the calculated steering acceleration for chaining.

getTarget

public Location<T> getTarget()

Returns the target to seek.

setTarget

public Seek<T> setTarget(Location<T> target)

Sets the target to seek.

Returns:

this behavior for chaining.

setOwner

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

Description copied from class: SteeringBehavior

Sets the owner of this steering behavior.

Overrides:

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

Returns:

this behavior for chaining.

setEnabled

public Seek<T> setEnabled(boolean enabled)

Description copied from class: SteeringBehavior

Sets this steering behavior on/off.

Overrides:

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

Returns:

this behavior for chaining.

setLimiter

public Seek<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 SteeringBehavior<T extends com.badlogic.gdx.math.Vector<T>>

Returns:

this behavior for chaining.
