# Wire

> Represents a wire connection between an output port and an input port in a graph.

## Definition

* **Type:** Class
* **Namespace:** [Unity.GraphToolkit.Editor](/engine/6000.6/script-reference/unity/graphtoolkit/editor.md)
* **Assembly:** UnityEditor
* **Implements:** [IEquatable\<Wire>](https://learn.microsoft.com/dotnet/api/system.iequatable-1)

```csharp
public sealed class Wire : IEquatable<Wire>
```

## Remarks

A [Wire](/engine/6000.6/script-reference/unity/graphtoolkit/editor/wire.md) corresponds to the connection between two ports, including connections that pass through wire portals. Use [Graph.GetWire](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graph/getwire.md) to obtain a [Wire](/engine/6000.6/script-reference/unity/graphtoolkit/editor/wire.md) for a connected port pair.

Additional Resources: [Graph.GetWire](/engine/6000.6/script-reference/unity/graphtoolkit/editor/graph/getwire.md), [IPort](/engine/6000.6/script-reference/unity/graphtoolkit/editor/iport.md)

Retrieve a wire between two connected ports and customize its visual properties on the graph canvas.

## Examples

```csharp
Wire wire = graph.GetWire(outputPort, inputPort);
wire.WidthOverride = 4f;
wire.Opacity = 0.5f;
wire.IsDashed = true;
```

| [Opacity](/engine/6000.6/script-reference/unity/graphtoolkit/editor/wire/opacity.md)             | The opacity multiplier applied to the wire.                                                                                          |
| [OutputPort](/engine/6000.6/script-reference/unity/graphtoolkit/editor/wire/outputport.md)       | The output port at the start of the connection.                                                                                      |
| [WidthOverride](/engine/6000.6/script-reference/unity/graphtoolkit/editor/wire/widthoverride.md) | The width override applied to the wire.                                                                                              |
