Dynamics2DEnvironment

interface Dynamics2DEnvironment<T> : Physics2DEnvironment<T> , Euclidean2DEnvironment<T> (source)

Any implementing Environment should take care of physical dynamics, in particular collision detection and response. This interface provides some hooks in order to be able to manage some of the node's physical state.

Properties

open val origin: Euclidean2DPosition

abstract val shapeFactory: Euclidean2DShapeFactory

A factory of shapes compatible with this environment.

Functions

addGlobalReaction

abstract fun addGlobalReaction(p0: GlobalReaction<T>)

abstract fun addLayer(p0: Molecule, p1: Layer<T, Euclidean2DPosition>)

abstract fun addNode(p0: Node<T>, p1: Euclidean2DPosition): Boolean

abstract fun addTerminator(p0: Predicate<Environment<T, Euclidean2DPosition>>)

farthestPositionReachable

abstract fun farthestPositionReachable(node: Node<T>, desiredPosition: Euclidean2DPosition, hitboxRadius: Double = getShape(node).radius): Euclidean2DPosition

Computes the farthest position reachable by a node towards a desiredPosition, avoiding node overlapping. If no node is located in between, desiredPosition is returned. Otherwise, the first position where the node collides with someone else is returned. For collision purposes, hitboxes are used: each node is given a circular hitbox of radius equal to its shape's radius (shapeless nodes can't cause overlapping). The client can specify a different radius for the hitbox of the moving node.
