public static void DrawLine(Vector3 p1, Vector3 p2);


Draw a line from p1 to p2.

Draw Line in the Scene View.

// Draw lines to the connected game objects that a script has.
// If the target object doesnt have any game objects attached
// then it draws a line from the object to (0, 0, 0).

using UnityEditor; using UnityEngine;

[CustomEditor(typeof(ConnectedObjectsExampleScript))] class ConnectLineHandleExampleScript : Editor { void OnSceneGUI() { ConnectedObjectsExampleScript connectedObjects = target as ConnectedObjectsExampleScript; if (connectedObjects.objs == null) return;

Vector3 center = connectedObjects.transform.position; for (int i = 0; i < connectedObjects.objs.Length; i++) { GameObject connectedObject = connectedObjects.objs[i]; if (connectedObject) { Handles.DrawLine(center, connectedObject.transform.position); } else { Handles.DrawLine(center,; } } } }

And the script attached to this Handle:
