The two examples below give the same result.

using UnityEngine;

public class Example : MonoBehaviour { // check if there is a rigidbody attached to this transform void Start() { if (GetComponent<Rigidbody>()) { Debug.Log("Rigidbody attached to this transform"); } } }

using UnityEngine;

public class Example : MonoBehaviour { // check if there is a rigidbody attached to this transform void Start() { if (GetComponent<Rigidbody>() != null) { Debug.Log("Rigidbody attached to this transform"); } } }
