*PolyLine that connects all the objects in the Scene View.*

```csharp
// Draw lines between selected GameObjects.

using UnityEditor;
using UnityEngine;
using System.Collections;

[CustomEditor(typeof(DrawPolyLineExample))]
public class PolyLineDraw : Editor
{
    private Vector3[] positions;

    void OnSceneGUI()
    {
        DrawPolyLineExample connectedObjects = target as DrawPolyLineExample;
        if (connectedObjects.objs == null)
        {
            return;
        }

        if (connectedObjects.objs.Length > 0)
        {
            positions = new Vector3[connectedObjects.objs.Length];
        }

        for (var i = 0; i < connectedObjects.objs.Length; i++)
        {
            if (connectedObjects.objs[i])
            {
                positions[i] = connectedObjects.objs[i].transform.position;
            }
            else
            {
                positions[i] = Vector3.zero;
            }
        }

        Handles.DrawPolyLine(positions);
    }
}
```

And the script attached to this handle:

```csharp
using UnityEngine;

public class DrawPolyLineExample : MonoBehaviour
{
    public GameObject[] objs;
}
