fix script to get C# var from another object instead of object this script is attached to

Questions & Answers

I have this script which in theory I want it to disable the player’s C# car controller script when the game over canvas it’s attached to is enabled when the race is over. The problems I’m having that this script setup only works for other C# scripts that are attached to the object that has this script? To fix this is it as easy as putting the player object in a GameObject variable and just edit the GetComponent action to have the script find the player’s controller script?

public class GameOverPause2P : MonoBehaviour {
	public PlayerCar scriptPlayerCar;
	public PlayerCar2 scriptPlayerCar2;

	void Start()
	{
		scriptPlayerCar = GetComponent<PlayerCar> ();
		scritpPlayerCar2 = GetComponent<PlayerCar2> ();
		scriptPlayerCar.enabled = false;
		scriptPlayerCar2.enabled = false;

	}
	
	// Update is called once per frame
	void Update () {
		
	}
}

sounds like using static variables might be an easy solution if have a condition that is to be shared by all your cars. then no look ups are necessary.

	public static bool RaceIsOver;

        void Update () {
		if (RaceIsOver==true) {

			//if ANY car changes the bool to true
			// all cars will do this here 
			//because static variables are
			// shared by all

				}
	
	}

if you want to change or check a static variable from another script you simply would say:

    //no lookup nessesary!!!!
    nameOfScript.RaceIsOver = true;

public class GameOverPause2P : MonoBehaviour {

     // reference the player GO's in order to retrieve their respective script components
     public GameObject PlayerCar1;
     public GameObject PlayerCar2;
     public PlayerCar scriptPlayerCar;
     public PlayerCar2 scriptPlayerCar2;

     // game over is false by default
     public bool GameOver = false;

 
     void Start()
     {

        // grab the script component for both players
        Player1CarControllerScript = PlayerCar1.GetComponent<ScriptPlayerCar>();
        Player2CarControllerScript = PlayerCar2.GetComponent<ScriptPlayerCar2>();

         scriptPlayerCar = GetComponent<PlayerCar> ();
         scriptPlayerCar2 = GetComponent<PlayerCar2> ();
         scriptPlayerCar.enabled = false;
         scriptPlayerCar2.enabled = false;
 
     }
     
     // Update is called once per frame
     void Update () {

        if (GameOver == true) {

            // disable CarControllerScript component attached to player
            Player1CarControllerScript.enabled = false;
            Player2CarControllerScript.enabled = false;

        }
     
     }
 }
