Summary - C# Basics

In this group, you learned the building blocks of C# programming in Unity. You saw that C# scripts inherit from the MonoBehaviour class and must be attached to a GameObject to execute in the scene. You mastered variable types (int, float, string, bool), namespaces (using UnityEngine;), and printing to the Console window with Debug.Log.

using UnityEngine;

public class GameController : MonoBehaviour
{
    public int score = 0;
    public void AddScore() { score += 10; }
}

These fundamentals form the foundation for creating moving characters and advanced game mechanics in your scenes.

Exercise Complete the Hero class

Inside the Hero class, define fields public string heroName = "Savasci"; and public int hp = 100;. Inside the Status method, use Debug.Log to print "Kahraman: " + heroName + " - HP: " + hp.

Show example solution

using System;

public static class Debug
{
    public static void Log(object message) => Console.WriteLine(message);
}

public class Hero
{
    public string heroName = "Savasci";
    public int hp = 100;

    public void Status()
    {
        Debug.Log("Kahraman: " + heroName + " - HP: " + hp);
    }
}

public class Program
{
    public static void Main()
    {
        Hero hero = new Hero();
        hero.Status();
    }
}

Test yourself

Which of the following is TRUE about a C# script created in Unity?
- The script file name and class name must be completely different.
- For a script to run in the scene, it must be attached to a GameObject as a component.
- In C#, no letter suffix can be placed after numbers of type float.
- The Debug.Log command only works after the game is published in a store.
Show answer

For a script to run in the scene, it must be attached to a GameObject as a component. — In Unity, scripts cannot participate in the game loop and do not execute unless attached as a component to a GameObject in the scene.
