Renderer.enabled

var enabled : boolean

Description

Makes the rendered 3D object visible if enabled.

JavaScript
    // make the object invisible
renderer.enabled = false;

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
void Example() {
renderer.enabled = false;
}
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

def Example():
renderer.enabled = false

Another example:
JavaScript
    // Toggle the Object's visibility each second.
// make the object visible
renderer.enabled = true;
function Update () {
// Find out whether current second is odd or even
var seconds : int = Time.time;
var oddeven = (seconds % 2) == 0;
// Enable renderer accordingly
renderer.enabled = oddeven;
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
void Update() {
int seconds = Time.time;
bool oddeven = seconds % 2 == 0;
renderer.enabled = oddeven;
}
void Example() {
renderer.enabled = true;
}
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

def Update():
seconds as int = Time.time
oddeven as bool = ((seconds % 2) == 0)
renderer.enabled = oddeven

def Example():
renderer.enabled = true
