public static void DrawPolyLine(params Vector3[] points);


Draw a line going through the list of points.

Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.

PolyLine that connects all the objects in the Scene View.

// 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] =; } }

Handles.DrawPolyLine(positions); } }

And the script attached to this handle:

using UnityEngine;

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