c#小白寻求帮助

'Object reference not set to an instance of an object' 不懂怎么解决，我写这个是为了读取TXT文本中的角度数据至二维数组，然后每隔一段时间更改物体的角度，但是使用二维数组时出现了问题。小白不懂怎么解决。

using UnityEngine;  
using System.Collections;  
using System.IO;  
using UnityEngine.UI;  
using System.Collections.Generic;  
public class loadtest : MonoBehaviour  
{  
	public TextAsset txtRawFile;  
	public Text uiText;   

	public float timer = 1.0f;
	public int z = 0;

	public float[,] spaces;

	private List<string> eachLine;  
	private string theWholeFileAsOneLongString;  

	// Use this for initialization  
	void Start ()  
	{  

		theWholeFileAsOneLongString = txtRawFile.text;  

		eachLine = new List<string>();  
		eachLine.AddRange(theWholeFileAsOneLongString.Split("\n"[0]));  

		float[,] spaces = new float[eachLine.Count, 6];         // 获取整数数组  

		for (int i = 0; i < eachLine.Count; i++) {               // 逐行转换  
			string st = eachLine[i];            // 取得一行  

			string[] nums = st.Split(new[] { ',' });  
			if (nums.Length != 6) {  
				Debug.Log ("Misforned input on line "+i+1);  
			}  
			for (int j = 0; j < Mathf.Min (nums.Length, 6); j++) {  
				float val;  
				if (float.TryParse (nums[j], out val))  
					spaces[i,j] = val;  
				else  
					spaces[i,j] = -1;  
			}  
		}  

	}
	void Update(){
		timer -= Time.deltaTime;
		if(timer<=0) {
			transform.localEulerAngles = new Vector3 (0, 0,-spaces[z,0]*57);
			Debug.Log (z);
			timer = 1.0f;
			z = z + 1;
		}
}
}

错误提示是这一句出现问题‘transform.localEulerAngles = new Vector3 (0, 0,-spaces[z,0]*57);’
希望各位可以帮忙我解决一下，给点思路。

您知道 Object reference not set to an instance of an object 的中文意思吗？

有个Null

未将对象引用到实例 一个对象还没有实例化，就去读取它的属性或方法，就会报这个错 具体你这里，就是transform对象没有实例化
