Object.operator bool

static implicit function bool (exists : Object) : boolean

Description

Does the object exist?

The two examples below give the same result.

JavaScript
    // check if there is a rigidbody attached to this transform
if (rigidbody)
Debug.Log("Rigidbody attached to this transform");

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
void Example() {
if (rigidbody)
Debug.Log("Rigidbody attached to this transform");

}
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

def Example():
if rigidbody:
Debug.Log('Rigidbody attached to this transform')

...is the same as this...
JavaScript
    // another way to check if a rigidbody is attached to this transform
if (rigidbody != null)
Debug.Log("Rigidbody attached to this transform");

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
void Example() {
if (rigidbody != null)
Debug.Log("Rigidbody attached to this transform");

}
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

def Example():
if rigidbody != null:
Debug.Log('Rigidbody attached to this transform')
