Code from api reference giving me: "NullReferenceException: Object reference not set to an instance of an object"
This is the code.
using UnityEngine;
using System.Collections;
public class PlayerController : MonoBehaviour {
public Rigidbody bullet;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetButtonDown("Fire1")) {
Rigidbody clone = Instantiate(bullet, transform.position, transform.rotation) as Rigidbody;
clone.velocity = transform.TransformDirection (Vector3.forward * 10);
}
}
}
The error is coming from this line: clone.velocity = transform.TransformDirection (Vector3.forward * 10);
And yes the attached object for the bullet is a rigidbody. This code is from the api reference.
This code works for me. I created an empty game object, added a Rigidbody component, assigned it to the bullet property in the editor, and everything works as expected.
What object do you have the script assigned to? Does it actually have a transform? That's the only other object that could be null.
Add Debug.Log messages inside your if. Log whether or not bullet is null, whether or not transform is null. After cloning, log wether or not clone is null.
Dave pointed it out, but it has to be that you don't have something assigned to your public bullet field. In the inspector you have to drag an object (with a rigidbody) onto it in the inspector.
Clone is definitely null after you try to instantiate your bullet (if transform were null it'd fail on the previous line). The fact that clone is null means either you didn't instantiate anything (bullet is null) or what you did instantiate didn't have a rigidbody (so the cast failed).
So check your "bullet" has a rigid body and that you have assigned it to bullet (via dragging it in the inspector).
