using UnityEditor;

// draw a red circle around the scene cube

[CustomEditor(typeof(CubeExample))] public class CubeEditor : Editor { void OnSceneGUI() { CubeExample cubeExample = (CubeExample)target;

Handles.color =; Handles.DrawWireDisc(cubeExample.transform.position, new Vector3(0, 1, 0), cubeExample.circleSize); } }

The cube:

using UnityEngine;

public class CubeExample : MonoBehaviour { public float circleSize = 3.0f;

void Awake() { Debug.Log("Cube"); } }
