Object.operator ==

파라미터

설명

Compares two object references to see if they refer to the same object.

no example available in C#

Get early out if there is no target.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Transform target;
    void Update() {
        if (target == null)
            return;
        
    }
}

Be careful when comparing with null.

e.g.

GameObject go = new GameObject();
Debug.Log (go == null); // false

Object obj = new Object();
Debug.Log (obj == null); // true

Instatiating a GameObject adds it to the scene so its completely initialized (!destroyed). Instantiating a simple UnityEngine.Object has no such semantics, so the it stays in the 'destroyed' state which compares true to null.
