Does the object exist?
The two examples below give the same result.
// check if there is a rigidbody attached to this transform
if (rigidbody) Debug.Log("Rigidbody attached to this transform");
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { void Example() { if (rigidbody) Debug.Log("Rigidbody attached to this transform"); } }
...is the same as this...
// another way to check if a rigidbody is attached to this transform
if (rigidbody != null) Debug.Log("Rigidbody attached to this transform");
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { void Example() { if (rigidbody != null) Debug.Log("Rigidbody attached to this transform"); } }
