Score system

Learn game progression with a script that tracks score.

Score System and Singleton Pattern

A central ScoreManager tracks points collected throughout the session. To allow other scripts effortless access, a static instance (Singleton pattern) is used.

public class ScoreManager : MonoBehaviour {
    public static ScoreManager instance;
    public int score = 0;
    void Awake() {
        instance = this;
    }
}

This allows any pickup script to register points directly with ScoreManager.instance.AddScore(10); in a single line.

Reflecting Score on UI Text

Whenever score increments, the screen user interface (UI) must reflect the updated total. The text property of the UI Text component is reassigned.

public void AddScore(int amount) {
    score += amount;
    scoreText.text = "Skor: " + score;
}

This offers immediate visual reward as players witness their points count increase on screen.

Exercise Score update test

Define a Start method. Inside, declare int skor = 100; and print "Guncel skor: " + skor to the console.

Show example solution

using UnityEngine;

public class ScoreTester : MonoBehaviour
{
    void Start()
    {
        int skor = 100;
        Debug.Log("Guncel skor: " + skor);
    }
}

Test yourself

Which architectural approach allows other classes to access ScoreManager directly via 'ScoreManager.instance.AddScore(10)'?
- Shader Pass
- Singleton Pattern (static instance)
- Perlin Noise Filter
- NavMesh Obstacle
Show answer

Singleton Pattern (static instance) — The Singleton pattern exposes a static instance reference granting global access to the object from any scene script.

Update UI score text

scoreText.____ = "Skor: " + currentScore;

Show answer

scoreText.text = "Skor: " + currentScore;
