Creation of a score system in unity

Question

I am currently developing a simple 2D game to learn many things about game development.

Nevertheless, I have some issues to create a score system.

I want to update the score every second, and adding 1 point for each second, and stop the count when the game is over.

I start to write this

public class scoremanager : MonoBehaviour {

    public int score;
    public GUIText distance;

    void Start () {
        score = 0;
    }

    void Update () {
        StartCoroutine(updateScoreManager(1f, 1));
        distance.text = score.ToString();
    }

    IEnumerator updateScoreManager(float totalTime, int amount) {
        score += amount; 
        yield return new WaitForSeconds (totalTime);
    }
}

The issues are that nothing shows up in the GUIText so I don't know if it works. And how can I stop the count when the game is over?

Answer 1

I guess simple solution to your problem is InvokeRepeating

//Invokes the method methodName in time seconds, then repeatedly every repeatRate seconds.
public void InvokeRepeating(string methodName, float time, float repeatRate);

So your transfomed code colud be

public class scoremanager : MonoBehaviour {

public int score;
public GUIText distance;

void Start () {
   InvokeRepeating("updateScoreManager",1f,1f);
}

void Update () {
    distance.text = score.ToString();
}

void updateScoreManager() {
    score += 1; 
}
