Object.bool

설명

Does the object exist?

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");
        }
    }
}

...is the same as this...

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");
        }
    }
}
