Scripting Gravity 2/8 Tutorial - Code error

Hi, I'm having a problem with the Scripting Gravity [2/8] tutorial:

I get the following error in the console:

NullReferenceException: Object reference not set to an instance of an object
PhysicsObject.Movement (Vector2 move) (at Assets/PhysicsObject.cs:40)
PhysicsObject.FixedUpdate () (at Assets/PhysicsObject.cs:35)

I can't see how my code differs from the example:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PhysicsObject : MonoBehaviour {
6.  
7.     public float gravityModifier = 1f;
8.  
9.     protected Rigidbody2D rb2d;
10.     protected Vector2 velocity;
11.  
12.     void onEnable()
13.     {
14.         rb2d = GetComponent<Rigidbody2D> ();
15.     }
16.  
17.     // Use this for initialization
18.     void Start () {
19.        
20.     }
21.    
22.     // Update is called once per frame
23.     void Update () {
24.        
25.     }
26.  
27.     void FixedUpdate()
28.     {
29.         velocity += gravityModifier * Physics2D.gravity * Time.deltaTime;
30.  
31.         Vector2 deltaPosition = velocity * Time.deltaTime;
32.  
33.         Vector2 move = Vector2.up * deltaPosition.y;
34.  
35.         Movement (move);
36.     }
37.  
38.         void Movement(Vector2 move)
39.     {
40.         rb2d.position = rb2d.position + move;
41.     }
42.  
43. }
44.  

Using Unity 2017.1.0f3 personal.

 

I found the problem - Line 12

Code (CSharp):

1. void onEnable()

Should be a capital 'O' at OnEnable

Code (CSharp):

1. void OnEnable()

So the rb2d variable wasn't being assigned, as OnEnable wasn't doing anything, and onEnable was never called.

A swine to track down, but taught me a few things. Onwards and upwards!

 

had the same issue lol feel like an idiot
