How to Start Programming Video Games from Scratch

Have you ever dreamed of creating your own video game and playing it with your friends? Imagine the thrill of seeing your ideas come to life on the screen! Programming video games from scratch might seem challenging, but it’s actually quite achievable. In this article, we’ll guide you step-by-step on how to start programming video games from scratch.

Why Start Programming Video Games?

Programming video games is not only fun but also educational. It helps you understand how computers work and improves your problem-solving skills. Plus, you get to be creative and make something unique. Ready to dive in? Let’s get started!

Step 1: Understanding the Basics

What is a Video Game?

A video game is an electronic game that involves interaction with a user interface to generate visual feedback on a two- or three-dimensional video display device. The player interacts with the game through controls, such as a keyboard, mouse, or game controller.

Basic Concepts in Game Programming

Before you start, it’s important to understand some basic concepts:

• Sprites: These are the images or characters in the game.
• Game Loop: This is the core of the game where all the actions take place, like moving characters and checking for collisions.
• Events: These are actions that happen in the game, like pressing a button or an enemy appearing.

Step 2: Choosing the Right Tools

To start programming video games, you’ll need some tools. Here are a few beginner-friendly options:

Game Engines

A game engine is a software framework designed for the creation and development of video games. They provide a lot of the base functionality you need, so you don’t have to write everything from scratch.

• Unity: Great for beginners, supports 2D and 3D games, and has a lot of tutorials.
• Unreal Engine: Known for its high-quality graphics, but a bit more complex than Unity.
• Godot: An open-source engine that’s easy to use and great for 2D games.

Programming Languages

You’ll also need to know a programming language. Here are the most common ones for game development:

• C#: Used with Unity, it’s a beginner-friendly language.
• C++: Used with Unreal Engine, it’s more powerful but harder to learn.
• Python: Great for beginners and used with simpler game engines like Pygame.

Step 3: Learning the Basics of Programming

If you’re new to programming, don’t worry! Here’s a simple guide to get you started:

Basic Programming Concepts

• Variables: These store information, like the score in a game.
• Loops: These repeat actions, like moving a character across the screen.
• Conditions: These make decisions, like checking if a player has won the game.
• Functions: These are reusable pieces of code that perform a specific task.

Resources to Learn Programming

There are many resources available online to learn programming:

• Codecademy: Offers interactive courses in various programming languages.
• Khan Academy: Provides free tutorials on basic programming concepts.
• Coursera: Offers courses from top universities on game development and programming.

Step 4: Creating Your First Game

Now that you have the basics down, it’s time to create your first game. Let’s start with a simple one: a basic 2D game where a character collects coins.

Planning Your Game

Before you start coding, plan your game:

• Concept: A character collects coins while avoiding obstacles.
• Characters: The player character and obstacles.
• Goals: Collect as many coins as possible without hitting obstacles.

Setting Up Your Game Engine

1. Download and install Unity.
2. Create a new project: Name it something like “CoinCollector.”
3. Set up the scene: This is where your game takes place. Add a background, the player character, and coins.

Coding the Game

1. Move the Character:csharpCopiar códigousing UnityEngine; public class PlayerController : MonoBehaviour { public float speed = 5.0f; void Update() { float moveHorizontal = Input.GetAxis("Horizontal"); float moveVertical = Input.GetAxis("Vertical"); Vector3 movement = new Vector3(moveHorizontal, moveVertical, 0.0f); transform.Translate(movement * speed * Time.deltaTime); } }
2. Collect Coins:csharpCopiar códigovoid OnTriggerEnter2D(Collider2D other) { if (other.gameObject.CompareTag("Coin")) { other.gameObject.SetActive(false); // Update score } }

Testing and Debugging

Once you’ve written your code, test your game. Play it to see if everything works as expected. If you find any bugs, don’t get discouraged. Debugging is a normal part of programming. Check your code for errors and fix them.

Step 5: Expanding Your Game

Once your basic game is up and running, you can start adding more features:

• Levels: Create different levels with increasing difficulty.
• Enemies: Add characters that the player must avoid.
• Power-ups: Add items that give the player special abilities.

Conclusion

Programming video games from scratch is an exciting and rewarding journey. Start with simple games and gradually move on to more complex projects. Remember, the key is to keep practicing and never give up. Your dream game is just a few lines of code away!
