This method allows to add a new node to this environment in a specific position. The environment is responsible to call the right method of the simulation in order to ensure that the reaction is properly scheduled. The function returns true if the node is added to the environment.

Adds to the simulation a predicate that determines whether a simulation should be terminated.

farthestPositionReachable

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