Add the following script to your Assets folder as PositionHandleExample.cs and add the PositionHandleExample component to an object in a Scene.

using UnityEngine;

[ExecuteInEditMode] public class PositionHandleExample : MonoBehaviour { public Vector3 targetPosition { get { return m_TargetPosition; } set { m_TargetPosition = value; } } [SerializeField] private Vector3 m_TargetPosition = new Vector3(1f, 0f, 2f);

public virtual void Update() { transform.LookAt(m_TargetPosition); } }

Add the following script to Assets/Editor as PositionHandleExampleEditor.cs and select the object with the PositionHandleExample component.

using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(PositionHandleExample)), CanEditMultipleObjects] public class PositionHandleExampleEditor : Editor { protected virtual void OnSceneGUI() { PositionHandleExample example = (PositionHandleExample)target;

EditorGUI.BeginChangeCheck(); Vector3 newTargetPosition = Handles.PositionHandle(example.targetPosition, Quaternion.identity); if (EditorGUI.EndChangeCheck()) { Undo.RecordObject(example, "Change Look At Target Position"); example.targetPosition = newTargetPosition; example.Update(); } } }
