# addConnections(to:bidirectional:)

Connects this node to all nodes in the specified list.

```
func addConnections(to nodes: [GKGraphNode], bidirectional: Bool)
```

## Parameters

`nodes`

The list of nodes to which to form connections.

`bidirectional`

<doc://com.apple.documentation/documentation/Swift/true> to create a connection in both directions; <doc://com.apple.documentation/documentation/Swift/false> to create only connections from this node to each of the specified nodes.

## Discussion

In GameplayKit, the connections between nodes in a graph are directional. For example, if the [`connectedNodes`](/documentation/GameplayKit/GKGraphNode/connectedNodes) list of Node A contains Node B, then a traveler on the graph can move directly from Node A to Node B. For the reverse to also be true, the [`connectedNodes`](/documentation/GameplayKit/GKGraphNode/connectedNodes) list of Node B must contain Node A. Use the `bidirectional` parameter to choose whether to automatically create connections in both directions or create only one-way connections.
