# GKGridGraphNode

A node in a navigation graph, associated with a position on a discrete two-dimensional grid.

## Declaration

```swift
class GKGridGraphNode
```

## Overview

Overview Together, a network of nodes form a graph that describes the navigability of a game world. Use graph nodes with a GKGridGraph object (and methods of its superclass GKGraph) to perform actions that relate to the network of nodes as a whole, such as pathfinding to determine routes through the network. To learn more about graphs and pathfinding, see Pathfinding in GameplayKit Programming Guide.
