CognitiveAgentWander

open class CognitiveAgentWander<T>(val environment: Physics2DEnvironment<T>, reaction: NodeReaction<T>, pedestrian: PedestrianProperty<T>, randomGenerator: RandomGenerator, offset: Double, radius: Double) : AbstractSteeringActionWithTarget<T, Euclidean2DPosition, Euclidean2DTransformation>

Produces a wandering steering action that simulates a random walk by targeting points on a circle centered at a given offset from the node and with a given radius.

The node's heading is set randomly and subsequent target points are chosen on a circumference around the heading with the specified offset and radius. The resulting target is constrained by the node's maximum walking distance.

Parameters

reaction

the reaction executing this action.

pedestrian

the owner of this action.

Type Parameters

the concentration type.

Constructors

CognitiveAgentWander

constructor(environment: Physics2DEnvironment<T>, reaction: NodeReaction<T>, pedestrian: PedestrianProperty<T>, randomGenerator: RandomGenerator, offset: Double, radius: Double)

Properties

environment

open override val environment: Physics2DEnvironment<T>

the physics environment in which the node moves.

maxWalk

open val maxWalk: Double

The maximum distance the node can walk, this is a length.

reaction

override val reaction: NodeReaction<T>

The NodeReaction owning this action, hosted by targetNode.

targetNode

val targetNode: Node<T>

Functions

cloneAction

override fun cloneAction(newReaction: Reaction<T>): Action<T>

Creates an equivalent action owned by newReaction, such as a reaction cloned onto a new node. An action targeting the host of its reaction targets the host of newReaction, which must then be a Node; an action targeting any other node keeps its target.

execute

open override fun execute()

Moves the node according to getNextPosition, in absolute or relative coordinates depending on isAbsolute.

getNextPosition

open override fun getNextPosition(): Euclidean2DPosition

nextPosition

open override fun nextPosition(): Euclidean2DPosition

shouldEqual

infix fun Action<*>.shouldEqual(other: Action<*>)

target

open override fun target(): Euclidean2DPosition

Returns the absolute target position this action points to.

targetDistanceTo

open fun targetDistanceTo(node: Node<T>, environment: Environment<T, Euclidean2DPosition>): Double

Computes the distance between this action's target and the given node within the provided environment.

toString

open override fun toString(): String
