Node

class Node(var position: Vector2, var prevPosition: Vector2, var velocity: Vector2, var inverseMass: Double = 1.0, var radius: Double = 0.0, var id: Int = 0)(source)

Represents a single physical node with position, velocity, and related properties.

A node serves as an element in simulations, with attributes including its current position, previous position, velocity, inverse mass, radius, and a unique identifier. These properties define the motion and interaction of the node with forces or other nodes in the simulation.

Constructors

constructor(position: Vector2, prevPosition: Vector2, velocity: Vector2, inverseMass: Double = 1.0, radius: Double = 0.0, id: Int = 0)

Properties

val bounds: Rectangle

a bounding rectangle centered around the node, with dimensions based on its radius.

var id: Int

an optional unique identifier for the node. Default is 0.

var inverseMass: Double

the reciprocal of the node's mass. A value of 0 represents an immovable object, while higher values represent lower mass.

var position: Vector2

the current position of the node in the simulation space.

var prevPosition: Vector2

the position of the node in the previous simulation step.

var radius: Double

the radius of the node, used for interactions or spatial calculations.

var velocity: Vector2

the current velocity of the node.
