GKGraph.FindPath(GKGraphNode, GKGraphNode) メソッド

定義

名前空間:

GameplayKit

アセンブリ:

Xamarin.iOS.dll

最小コストの順パスを表す T:GamplayKit.GKGraphNode の配列を返します。 パスが存在しない場合は、空の配列を返します。

単純なグラフでのパスファインディングを次に示します。

var a = GKGraphNode2D.FromPoint (new Vector2 (0, 5));
var b = GKGraphNode2D.FromPoint (new Vector2 (3, 0));
var c = GKGraphNode2D.FromPoint (new Vector2 (2, 6));
var d = GKGraphNode2D.FromPoint (new Vector2 (4, 6));
var e = GKGraphNode2D.FromPoint (new Vector2 (2, 5));
var f = GKGraphNode2D.FromPoint (new Vector2 (2, 2));

a.AddConnections (new [] { b, c }, false);
b.AddConnections (new [] { e, f }, false);
c.AddConnections (new [] { d }, false);
d.AddConnections (new [] { e, f }, false);

var graph = GKGraph.FromNodes(new [] { a, b, c, d, e, f });

var a2e = graph.FindPath (a, e); // [ a, c, d, e ]
var a2f = graph.FindPath (a, f); // [ a, b, f ]
