GKGraph.FindPath(GKGraphNode, GKGraphNode) 方法

定义

命名空间:

GameplayKit

程序集:

Xamarin.iOS.dll

返回一个 T：GamplayKit.GKGraphNode ，表示成本最低的顺序路径。 如果不存在路径，则返回空数组。

[Foundation.Export("findPathFromNode:toNode:")]
public virtual GameplayKit.GKGraphNode[] FindPath (GameplayKit.GKGraphNode startNode, GameplayKit.GKGraphNode endNode);

abstract member FindPath : GameplayKit.GKGraphNode * GameplayKit.GKGraphNode -> GameplayKit.GKGraphNode[]
override this.FindPath : GameplayKit.GKGraphNode * GameplayKit.GKGraphNode -> GameplayKit.GKGraphNode[]

参数

startNode

GKGraphNode

endNode

GKGraphNode

返回

GKGraphNode[]

属性

ExportAttribute

注解

下面演示了在简单图形上查找路径：

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 ]
