Unity Script Reference – Renderer.OnBecameInvisible

Renderer.OnBecameInvisible

function OnBecameInvisible () : void

Description

OnBecameInvisible is called when the object is no longer visible by any camera.

This message is sent to all scripts attached to the renderer. OnBecameVisible and OnBecameInvisible are useful to avoid computations that are only necessary when the object is visible.

JavaScript

// Disables the behaviour when it is invisible
function OnBecameInvisible () {
    enabled = false;
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    void OnBecameInvisible() {
        enabled = false;
    }
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    def OnBecameInvisible():
        enabled = false

Note that object is considered visible when it needs to be rendered in the scene. It might not be actually visible by any camera, but still need to be rendered for shadows for example. Also, when running in the editor, the scene view cameras will also cause this function to be called.
