NullReference help

Hi,

i have this code here:

Code (csharp):

1. using UnityEngine;
2. using System.Collections.Generic;
3.  
4. public class terrainCollumn{
5.  
6.     public Object block;
7.  
8.     public List<GameObject> blocks;
9.    
10.    
11.    
12.     //public int CollumnHeight = 50;
13.  
14.     // Use this for initialization
15.     public terrainCollumn () {
16.        
17.         block = Resources.Load("Block");
18.    
19.     }
20.    
21.    
22.     public int init(int gainedPoint, int gainedCollumnNumber)
23.     {
24.         for (int i = 0; i < gainedPoint; i++)
25.         {
26.             GameObject newBlock = MonoBehaviour.Instantiate(block,new Vector3((float)gainedCollumnNumber/4,(float)i/4,0), Quaternion.identity) as GameObject;
27.             MonoBehaviour.print(newBlock.GetType());
28.             blocks.Add(newBlock);
29.         }
30.        
31.         return gainedPoint + Random.Range(1,-2);
32.     }
33.    
34.  
35. }
36.  

But no matter how i turn it around it just stops at the blocks.Add(newBlock);

I tried to double and tripple check if the type is the needed type, and i should not have a nulref because i can obviously get the name/type in just 1 line before.

You have to create the List first by using "blocks = new List<GameObject>()" inside your start function or wherever.

 

I feel so retarded now. wow...

Thanks man!!
( , mb i programed egnouth today)

 

Could you explain line 27?

 

@Dantus

As this class is not inherited from Monobehaviour, in order to still use the print, i have to access that static print function with a explicit Monobehaviour.print() call.

 

Interesting, I wasn't even aware that Unity has a lower case static method call in MonoBehaviour!? I though only Debug.Log existed for that.
