Problem NullReferenceException: Object reference not set to an instance of an object

I don't know if I'm legally suppose to post this in "AfterDawns" or not. I've accidently ticked of people due to my inexperience with programming (C#, which code I'm posting now is my first language). Here's a topic for example which seems to be no help (I've learned what arrays are in Mr. Adamson's video): http://www.reddit.com/r/learnprogramming/comments/2aom1z/back/

Once again my apologies of this is here illegally. Thanks.

Code:

using System.Collections;

public class Loops : MonoBehaviour {

   public class sonicHeroes {

   public int id; 
   public string knuckles;
   public string omega;
   public string big;



   public void powerCharacters() {

   print("Knuckles " + knuckles);
   print("Omega " + omega);
   print("Big " + big);


   }

   }

   void Start () {


   sonicHeroes[] powerCharac = new sonicHeroes[4];

   for (int i = 0; i <= 4; i++)

     {
       powerCharac[i] = new sonicHeroes();
       powerCharac[i].knuckles = "Knuckles";
       powerCharac[i].omega = "Omega";
       powerCharac[i].big = "Big";
    
    
     }
     for (int i = 0; i <= 4; i++)
     {
       powerCharac[i].powerCharacters();
  
    
     }

 

"Object reference not set to an instance of an object"

Correct ..

 

IS this for both loops or for the second one?

 

Thanks. I'm going on switch statements and I found this error which shows the red line by my method name getSonic () and break;

Code:

using UnityEngine;
using System.Collections;

public class RandomNumbers : MonoBehaviour {

    public class sonicTeams {
  
       
    public string teamSonic;
    public string teamDark;
    public string teamRose;
    public string teamChaotix;
    public int age;
    public int health;   
      
    public void teamInfo () {
  
    print("Team Sonic " + teamSonic);
    print("Team Dark " + teamDark);
    print("Team Rose " + teamRose);
    print("Team Chaotix " + teamChaotix);
  
        }
      
    }
  
    void Start () {
  
    float teamAge;
    float teamNumber;
    float teamSize;
    float teamHealth;
      
    sonicTeams[] sonicTeam = new sonicTeams[51];
  
        for (int i = 1; i <= 50; i++)
      
        {
            teamAge = Random.value;
            teamSize = Random.value;
          
            teamNumber = Mathf.RoundToInt(12 * teamAge + 4);
            teamHealth = Mathf.RoundToInt(5 * teamSize + 6);
          
          
            sonicTeam[i] = new sonicTeams();           
            sonicTeam[i].teamSonic = getSonic();
            sonicTeam[i].teamDark = getDark();
            sonicTeam[i].teamRose = getRose();
            sonicTeam[i].teamChaotix = getChaotix();
            sonicTeam[i].age = (int)teamNumber;
            sonicTeam[i].health = (int)teamHealth;
          
            }
        for (int i = 1; i <= 10; i++)
          
        {
            sonicTeam[i].teamInfo();
          
        }  
      
        string getSonic ()
          
        string tName;
        float rNum;
        int mySlot;  
      
        rNum = Random.value;
        mySelection = (int)Mathf.RoundToInt(10 * rNum + 4);  
      
        switch(mySelection) {
            case 1: tName = "Sonic"
            break;
            case 2: tName = "Tails";   
              
        }
    }
}

EDIT: Error codes are the following: Assets/RandomNumbers.cs(73,29): error CS1525: Unexpected symbol `break' and Assets/RandomNumbers.cs(62,32): error CS1525: Unexpected symbol `(', expecting `)', `,', `;', `[', or `='

 

I fixed the break issue.

 

May you tell me what I did wrong for this: string getSonic () { with this error code: Assets/RandomNumbers.cs(62,32): error CS1525: Unexpected symbol `(', expecting `)', `,', `;', `[', or `='

Code:

using UnityEngine;
using System.Collections;

public class RandomNumbers : MonoBehaviour {

    public class sonicTeams {
   
        
    public string teamSonic;
    public string teamDark;
    public string teamRose;
    public string teamChaotix;
    public int age;
    public int health;    
       
    public void teamInfo () {
   
    print("Team Sonic " + teamSonic);
    print("Team Dark " + teamDark);
    print("Team Rose " + teamRose);
    print("Team Chaotix " + teamChaotix);
   
        }
       
    }
   
    void Start () {
   
    float teamAge;
    float teamNumber;
    float teamSize;
    float teamHealth;
       
    sonicTeams[] sonicTeam = new sonicTeams[51];
   
        for (int i = 1; i <= 50; i++)
       
        {
            teamAge = Random.value;
            teamSize = Random.value;
           
            teamNumber = Mathf.RoundToInt(12 * teamAge + 4);
            teamHealth = Mathf.RoundToInt(5 * teamSize + 6);
           
           
            sonicTeam[i] = new sonicTeams();            
            sonicTeam[i].teamSonic = getSonic();
            sonicTeam[i].teamDark = getDark();
            sonicTeam[i].teamRose = getRose();
            sonicTeam[i].teamChaotix = getChaotix();
            sonicTeam[i].age = (int)teamNumber;
            sonicTeam[i].health = (int)teamHealth;
           
            }
        for (int i = 1; i <= 10; i++)
           
        {
            sonicTeam[i].teamInfo();
           
        }   
       
        string getSonic () {
           
       
        string tName;
        float rNum;
        int mySlot;   
       
        rNum = Random.value;
        mySelection = (int)Mathf.RoundToInt(2 * rNum + 1);   
       
        switch(mySelection) {
            case 1: tName = "Sonic";
            break;
            case 2: tName = "Tails";    
            break;
            case 3: tName = "Knuckles";
            break;       
               
        }
        }
   
    }
}

 

Back. I've seen this done in a video with no while loops (I don't know what those are yet) no anything except what I have posted. Mine's an almost exact replica of his code. What I'm trying to do is to run my switch statement in Unity's console. Here's my code:

Code:

public class teams {
       
        public string teamDark;
        public string teamSonic;
        public int teamRose;
        public int teamChaotix;
       
        public void teamData () {
       
        print("Team Dark " + teamDark);
        print("Team Sonic " + teamSonic);
        print("Team Rose " + teamRose);    
        print("Team Chaotix " + teamChaotix);
           
        }
       
    }

    void Start () {
   
    float teamNumber;    
    float teamSize;
    float teamPosition;
    float teamGin;
       
    teams[] teamInfo = new teams[51];
   
    for(int i = 1; i<= 50; i++)
       
        {   
       
        teamNumber = Random.value;
        teamPosition = Random.value;
           
        teamSize = (int)Mathf.RoundToInt(150 * teamNumber + 12);
        teamGin = (int)Mathf.RoundToInt(500 * teamPosition + 1);
       
        teamInfo[i] = new teams();
           
        teamInfo[i].teamDark = getDark();
        teamInfo[i].teamSonic = getSonic();
        teamInfo[i].teamRose = (int)teamSize;
        teamInfo[i].teamChaotix = (int)teamGin;
       
        }
        for(int  i = 1; i<= 10; i++)
       
        {
            teamInfo[i].teamData();
        }
    }
   
    string getDark () {
       
    string mRouge;
    float rShadow;
    int mySelection;
   
    rShadow = Random.value;
    mySelection = (int)Mathf.RoundToInt(6 * rShadow + 1);
   
    switch(mySelection){
   
       
        case 1: mRouge = "Rouge";
        break;
        case 2: mRouge = "Shadow";   
        break;
        case 3: mRouge = "Omega";
        break;    
        case 4: mRouge = "Team Dark";
        break;
        case 5: mRouge = "This Machine";
        break;
        default: mRouge = "Sonic Heroes";
        break;
       
        return mRouge;    
           
        }
    }
}

Here's the errors/warning:

1: error CS0161: `Switch.getDark()': not all code paths return a value
2: warning CS0162: Unreachable code detected
3: I know what to do with error number 3. But still tosses my error #1 error.

 

Thank you it works! That was a simple fix that I never really catch myself. Thank you.
