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.
Practice 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.
Starter code
using System;
public static class Debug
{
public static void Log(object message) => Console.WriteLine(message);
}
public class Hero
{
// heroName ve hp alanlarini tanimla
public void Status()
{
// Debug.Log ile yazdir
}
}
public class Program
{
public static void Main()
{
Hero hero = new Hero();
hero.Status();
}
}Sample 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();
}
}Expected output
Kahraman: Savasci - HP: 100
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 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. Correct answer
- 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.
Explanation: In Unity, scripts cannot participate in the game loop and do not execute unless attached as a component to a GameObject in the scene.
2 Inheriting MonoBehaviour
public class Enemy : ____
{
public int damage = 25;
}public class Enemy : MonoBehaviour
{
public int damage = 25;
}Explanation: Classes attached as components to a GameObject in Unity inherit from the MonoBehaviour class.
