Connection

a Swift path-finding library. Its primary goal is to extend Apple's GameplayKit framework.

Features

  • [x] Weighted connections.
  • [x] Total path weight.
  • [x] Associated values support.
  • [x] Find the shortest path between multiple origins and destinations.

Usage

Connection defines two new generic classes: Node and Graph, which are, respectively, GKGraphNode and GKGraph counterparts.

import Connection

// Create nodes.
let nodeA = Node(value: "A")
let nodeB = Node(value: "B")
let nodeC = Node(value: "C")

// Make connections.
nodeA.addConnection(to: nodeB, bidirectional: false, weight: 1)
nodeB.addConnection(to: nodeC, bidirectional: true, weight: 2)

// Create graph.
let graph = Graph([nodeA, nodeB, nodeC])

// Find path.
let shortestAtoCPath = graph.findPath(from: nodeA, to: nodeC)

print(shortestAtoCPath) // ["A", "B", "C"]

You can find many more examples in the Tests folder.

Installation

Connection is distributed using the Swift Package Manager. To install it into a project, follow this tutorial and use this repository URL: https://github.com/zntfdr/Connection.git.
