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.

open fun farthestPositionReachable(node: Node<T>, desiredPosition: Euclidean2DPosition, hitboxRadius: Double): 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.
