Position handle in the Scene View.''

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();
        }
    }
}
