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.
Practice Score update test
Define a Start method. Inside, declare int skor = 100; and print "Guncel skor: " + skor to the console.
Starter code
using UnityEngine;
public class ScoreTester : MonoBehaviour
{
// Start icinde skor tanimla ve yazdir
}Sample solution
using UnityEngine;
public class ScoreTester : MonoBehaviour
{
void Start()
{
int skor = 100;
Debug.Log("Guncel skor: " + skor);
}
}Expected output
Guncel skor: 100
Questions and answers

1 Which architectural approach allows other classes to access ScoreManager directly via 'ScoreManager.instance.AddScore(10)'?
- Shader Pass
- Singleton Pattern (static instance) Correct answer
- Perlin Noise Filter
- NavMesh Obstacle
Explanation: The Singleton pattern exposes a static instance reference granting global access to the object from any scene script.
2 Update UI score text
scoreText.____ = "Skor: " + currentScore;scoreText.text = "Skor: " + currentScore;Explanation: The 'text' property is assigned to update the string rendered by the UI text component.
