PhysicsEnvironment

interface PhysicsEnvironment<T, P : Position<P>, Vector<P>, A : Transformation<P>, F : GeometricShapeFactory<P, A>> : EuclideanEnvironment<T, P> (source)

An environment supporting physics and nodes shapes. Note: due to the high number of parameters it's highly recommended not to use this interface directly, but to create an apposite interface extending this one instead.

Parameters

factory of shapes compatible with this environment

Inheritors

Physics2DEnvironment

PhysicsEnvironmentWithObstacles

Properties

open val origin: P

abstract val shapeFactory: F

A factory of shapes compatible with this environment.

Functions

addGlobalReaction

abstract fun addGlobalReaction(p0: GlobalReaction<T>)

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

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

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

farthestPositionReachable

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

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.
