파라미터

x The first Object.
y The Object to compare against the first.

설명

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

using UnityEngine;

public class Example : MonoBehaviour { public Collider target; void OnTriggerEnter(Collider trigger) { if (trigger == target) { print("We hit the target trigger"); } } }

Get early out if there is no target.

using UnityEngine;

public class Example : MonoBehaviour { public Transform target; void Update() { // Early out if the target is gone if (target == null) { return; } } }

Be careful when comparing with null.

e.g.

using UnityEngine;

public class Example : MonoBehaviour { void Start() { 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.
