Object.bool

Description

该对象是否存在？

下面的两个示例将给出相同的结果。

using UnityEngine;
using System.Collections;

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

...等同于...

using UnityEngine;
using System.Collections;

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