Unity Script Reference – MonoBehaviour.OnDrawGizmosSelected

MonoBehaviour.OnDrawGizmosSelected

function OnDrawGizmosSelected () : void

Description

Implement this OnDrawGizmosSelected if you want to draw gizmos only if the object is selected.

Gizmos are drawn only when the object is selected. Gizmos are not pickable. This is used to ease setup. For example an explosion script could draw a sphere showing the explosion radius.

JavaScript

    var explosionRadius : float = 5.0;
    function OnDrawGizmosSelected () {
        // Display the explosion radius when selected
        Gizmos.color = Color.white;
        Gizmos.DrawSphere (transform.position, explosionRadius);
    }

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    public float explosionRadius = 5.0F;
    void OnDrawGizmosSelected() {
        Gizmos.color = Color.white;
        Gizmos.DrawSphere(transform.position, explosionRadius);
    }
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    public explosionRadius as single = 5.0F

    def OnDrawGizmosSelected():
        Gizmos.color = Color.white
        Gizmos.DrawSphere(transform.position, explosionRadius)
