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, Vector3.zero); } } } }
