How to instantiate Two Game Objects that require each other's data at the same time

Questions & Answers
1

I have two empty game objects (BlueTeam and RedTeam). The BlueTeam needs to set its opponent as the RedTeam and vice versa. When a team is instantiated it as to generate its players and place them on there home regions which are created when I Instantiate the pitch. When I instantiate one team only my players appear at the correct positions with no error. When I try to instantiate both teams at the same time I have a “Null Exception The Object which you are trying to reference doe not exist”. I know what the error means but I cant seem to get why that is happening.
Here is some code of what I am trying to do.
Here is my start function for my SoccerPitch

// Use this for initialization
	void Start()
	{   
		//create the soccer ball
		m_pBall = Instantiate(m_pBall) as SoccerBall;
		//create the teams
		m_pRedTeam = Instantiate(m_pRedTeam) as SoccerTeam;
	
		
		m_pBlueTeam = Instantiate(m_pBlueTeam) as SoccerTeam;
		
		m_bGameOn = true;
		m_bGoalKeeperHasBall = false;
		m_bPaused = false;
		
		
		
	}

Here is my Start function for my SoccerTeam

 // Use this for initialization
    	void Start () {
    	//initialize soccerball
    		m_pPitch = GameObject.FindGameObjectWithTag("soccerpitch").GetComponent<SoccerPitch>();
    		
    		
    		//initilize team home regions
    		if(transform.tag == "redteam")
    		{
    			m_pHomeGoal =  GameObject.FindGameObjectWithTag("redgoal").GetComponent<Goal>();
    			m_pHomeGoal.m_vFacing = new Vector3(0,1,0);
    			GeneratePlayers(m_pPlayersHomeRegions);
    			m_pOpponents = GameObject.FindGameObjectWithTag("blueteam").GetComponent<SoccerTeam>();
    			m_POpponentsGoal = GameObject.FindGameObjectWithTag("bluegoal").GetComponent<Goal>();
    			
    		}
    		
    		
    		if(transform.tag == "blueteam")
    		{
    			
    			m_pHomeGoal = GameObject.FindGameObjectWithTag("bluegoal").GetComponent<Goal>();
    			m_pHomeGoal.m_vFacing = new Vector3(0,-1,0);
m_pOpponents = GameObject.FindGameObjectWithTag("redteam").GetComponent<SoccerTeam>()
    		    m_POpponentsGoal = GameObject.FindGameObjectWithTag("redgoal").GetComponent<Goal>();
    			//create players for this team
    			GeneratePlayers(m_pPlayersHomeRegionsblue);
    		}
    		
    		m_pReceivingPlayer = null;
    
    	 }

Here is my start unction for my Field player.

// Use this for initialization
	public void Start(){
		
		m_vVelocity = new Vector3(0,0,0);
		m_vHeading = new Vector3(0,0, 0);
		rigidbody.velocity = new Vector3(0,0, 0);
		//m_pBall = GameObject.FindGameObjectWithTag("soccerBall");
		m_pSteering = new SteeringBehaviours(this.gameObject.GetComponent<FieldPlayer>(), GameObject.FindGameObjectWithTag("soccerBall").GetComponent<SoccerBall>());
			
											
		//initilize the statemachine
		m_pStateMachine = new StateMachine<FieldPlayer>(this);
		//intilize the states
		m_pStateMachine.SetCurrentState(Wait.Instance());
		this.Steering().SetTarget(this.HomeRegion().Pos());
		//set the players start position
		transform.position = (this.HomeRegion()).Pos() ;
											
	}

The Null Exception error points me to the FieldPlayer’s start function where I try to set the position of the FieldPlayer(transform.position = (this.HomeRegion()).Pos() :wink:
