Change an INT on one script via another

Questions & Answers
1

I know this has been asked probably many times before. I’m just learning, and having trouble associating the answers to my problem.

Creating block breaker. The 3 scripts i need help interacting with are ‘LevelManager’ ‘Brick’ and ‘Losecolider’. In my bricks script I have a score. I can access this score anywhere, and it works. YAY. In my losecolider I have lives. My ball hits the colider it loses lives and displays on screen perfectly. My levelmanager handles the levels and when level 1 is completed it sends me to a WIN level 1 screen. I want to be able to add 'if lives = 5 +100 on score. I’m not sure how to access them between scripts though, and change the variable. And would i do this on the level manager? Sorry for this ramble and I appreciate any help in advance!

BRICK SCORE SECTION

if (isBreakable) {
			score = score + 10;
			print (score);
			HandleHits();

LOSECOLIDER LIVES SECTION

void OnTriggerEnter2D (Collider2D trigger) {
		lives --;
		text.text = ("LIVES ") + lives.ToString();
		Ball.hasStarted = false;
		if (lives <= 0) {
			lives = 5;
			Brick.score = 0;
			levelManager = GameObject.FindObjectOfType<LevelManager>();
			levelManager.LoadLevel("Lose Screen");
		}

LEVEL MANAGER SCRIPT (WHAT I THINK SHOULD HAVE THE ANSWER)

public void BrickDestoyed() {
		if (Brick.breakableCount <= 0) {
			//THIS IS WHERE I THINK IT SHOULD GO???BUT NOT SURE HOW???
			// if (LoseCollider.lives = 5);
			//	Brick.score = Brick.score + 1000;
			LoadNextLevel();
			Ball.hasStarted = false;
			}

So you want to access a variable in one script from another.Right ?.You can do this in many ways.Will explain two ways here.Accessing public variable of one script from another using GetComponent() and through static method.

//The Brick.cs script
public class Brick:MonoBehaviour
{
  //Public score variable (method 1)
  public int Score_01;
  //Public static score variable (method 2)
  public static int Score_02;
}

//The LevelManager.cs script
public class LevelManager:Monobehaviour
{

  public void BrickDestroyed()
  {
    if(Brick.breakableCount<=0)
    {
      //Method One
      GameObject.FindObjectOfType<Brick>().Score_01 +=1000; 

      //OR Method two
      Brick.Score_02+=1000; 

      //Bothmethods are better if you have only one object with the Brick Script
      //The static Score_02 wont change its value even in scene changes
    }
  }

}

The static method is not well advised to use anywhere you want.Use it to access a public variable in a script that is applied to only one gameobject.You can use GameObject.FindObjectsOfType() to get all object with the same scripts assigned into an array.

Hope this helps you to get started
