Debug.Log for debugging in Unity - Mini Project: Build & Apply

Debug.Log for debugging

📖 Scenario: You are creating a simple Unity script to track the player's score during a game. You want to see the score updates in the Unity Console to make sure your code works correctly.

🎯 Goal: Build a Unity C# script that uses Debug.Log to print the player's score updates to the Console for easy debugging.

📋 What You'll Learn

Create an integer variable called score and set it to 0

Create an integer variable called pointsToAdd and set it to 10

Add pointsToAdd to score

Use Debug.Log to print the message "Score updated: " followed by the current score

💡 Why This Matters

🌍 Real World

Game developers use Debug.Log to check values and program flow while building games in Unity.

💼 Career

Knowing how to debug with Debug.Log is a basic but essential skill for Unity developers to find and fix issues quickly.

1

Create the initial score variable

Create an integer variable called score and set it to 0 inside the Start() method.

Unity

using UnityEngine;

public class ScoreTracker : MonoBehaviour
{
    void Start()
    {
        // Create an integer variable called score and set it to 0
        
    }
}

Need a hint?

Use int score = 0; inside the Start() method.

2

Add points to add variable

Inside the Start() method, create an integer variable called pointsToAdd and set it to 10.

Unity

using UnityEngine;

public class ScoreTracker : MonoBehaviour
{
    void Start()
    {
        int score = 0;
        // Create an integer variable called pointsToAdd and set it to 10
        
    }
}

Need a hint?

Use int pointsToAdd = 10; inside the Start() method.

3

Add points to the score

Inside the Start() method, add pointsToAdd to score using the += operator.

Unity

using UnityEngine;

public class ScoreTracker : MonoBehaviour
{
    void Start()
    {
        int score = 0;
        int pointsToAdd = 10;
        // Add pointsToAdd to score
        
    }
}

Need a hint?

Use score += pointsToAdd; to add points.

4

Print the updated score with Debug.Log

Use Debug.Log inside the Start() method to print the message "Score updated: " followed by the current score.

Unity

using UnityEngine;

public class ScoreTracker : MonoBehaviour
{
    void Start()
    {
        int score = 0;
        int pointsToAdd = 10;
        score += pointsToAdd;
        // Use Debug.Log to print "Score updated: " plus the score
        
    }
}

Need a hint?

Use Debug.Log("Score updated: " + score); to print the message.
