Godo Engine 4 Game Development Project
 |
Description
Book Introduction
Meet Godot 4, a powerful free and open-source game engine.
An introduction to the feature-rich, high-end game engine version 4.
With its many new features, Godo 4 is a powerful alternative to expensive commercial game engines.
This book consists of five projects that faithfully utilize the 2D and 3D capabilities of the Godot engine.
By following the process of creating a small game project, you will understand the high-level inner workings and learn development techniques that you can apply to your own projects.
Covers everything from the basics to sophisticated game physics and animation, with a simple step-by-step approach and practical examples.
It was updated based on the Korean version 4.2 instead of the original version 4.1, and a description of the high-level engine editor menu was added as an appendix to the Korean version.

Into the book
As a game developer, there are many benefits to using altitude.
First of all, since you are not restricted by commercial licenses, you have complete control over how and where you distribute your game.
Most commercial game engines either limit the types of projects you can create or require significantly more expensive licenses for certain genres of games, such as gambling.
/ The fact that Godot is open source also means that it has a level of transparency that is incomparable to commercial game engines.
For example, if you find that a particular engine feature doesn't meet your needs, you can freely modify the engine itself to add the new feature you need, without needing permission.
It also gives you full access to the inner workings of the engine, which can be very useful when debugging large projects.
--- p.6
Like Python, GDScript is a dynamically typed language.
This means that there is no need to declare a type when creating a variable.
We also use spaces (indentation) to indicate blocks of code.
Overall, the advantage of using GDScript for game logic is that it is tightly integrated with the engine, requiring less code to be written.
This means that development is faster and there is less need to correct mistakes.
/ I have prepared the following example code to give you an idea of what GDScript looks like.
A short script that moves a sprite from left to right on the screen at a set speed.
--- pp.15-16
We need to detect when the player hits a coin or an obstacle, but we haven't created these objects yet.
But that's okay.
It can be created using advanced signal functions.
Signals are a way for nodes to send messages that other nodes can detect and react to.
Most nodes have built-in signals that notify them when an event occurs (such as a body colliding or a button being pressed).
You can also define custom signals to suit your purposes.
/ The signal is used by connecting it to the node that wants to receive this signal.
Connections can be made in the Inspector window or in code.
Later in this project, you will learn how to connect signals in two ways.
--- p.32
However, there is one problem when running the game now.
All nodes are paused, including Main.
That is, since we are no longer processing _input(), we cannot detect input again to unpause it.
To solve this problem, set the Process/Mode of the Main node to Always.
The pause function is very useful to know.
Since this technique can be used in any game, let's review the feature again and make sure you understand how it works.
--- p.91
When you replay the game, you will be fighting aggressive enemy aliens.
Let's make sure all collision combinations are processed (except when the player gets hit by an enemy bullet).
Also note that enemy bullets can be blocked by rocks.
So you can hide behind a rock and take cover.
/ Now that there are enemies in the game, it's much more challenging.
If it's still too easy, try increasing enemy attributes, such as their appearance frequency, damage dealt, and the number of shots required to destroy them.
--- p.99
Moving platforms are a fun addition to your level design toolkit.
In this section, we'll create a moving platform that can be placed anywhere on the level and have its movement and speed set.
/ Start a new scene and add Node2D as the root node and rename it MovingPlatform.
Save the scene and add TileMap as a child.
Drawing the platforms is easy, as the platform art is all in sprite sheets, already broken down into tiles and with collision added.
Add tiles_world.tres to the Tile Set.
The Collision Animatable box must also be checked for use.
This way, collisions work properly even while moving.

Drawing the platforms is easy, as the platform art is all in sprite sheets, already broken down into tiles and with collision added.
Add tiles_world.tres to the Tile Set.
The Collision Animatable box must also be checked for use.
This way, collisions work properly even while moving.

Publisher's Review
Get started developing games with Godo Engine, the rising star of the game engine world. The Korean version includes an appendix that explains the Godo Engine editor menu.
Since the Unity pricing policy issue, the free open source game engine Godot Engine has been gaining popularity.
The Godot engine is easy to use, lightweight, and free of complex licensing issues, making it easy to distribute commercial games worldwide.
Moreover, version 4.0 added a number of new features comparable to those of expensive commercial game engines, making it the world's third-largest engine.
This marks the beginning of an era where individuals or small teams can create their own games using free engines.
However, until now, there has been little domestic reference material on high-altitude engines.
Although Godo Editor supports Korean 100%, most of the Godo 4 documentation remains untranslated.
In this situation, a book has been published that explains everything from how to use the editor to how to actually develop a game in an easy and detailed manner.
The book's five cross-platform 2D and 3D game project examples will help you quickly become familiar with the Godot engine and gain a solid understanding of how to develop games.
Instead of the original version 4.1, you can update to the Korean version 4.2 to easily utilize the latest features.
Chapter 1 introduces the general concepts and characteristics of game engines, and explains how to download Godot and how to use this book effectively.
In Chapter 2, you'll learn how to create scenes and work with Godot's node system, how to use the Godot editor, and how to write scripts in GDScript while creating a small 2D game called Coin Dash.
In Chapter 3, we'll learn how to create an Asteroids-style space game using physics bodies, while building the classic 2D arcade game Space Rock.
In Chapter 4, we will create Jungle Jump, a horizontal scrolling platform game in the style of Super Mario Bros.
You will learn about level design using kinematic bodies, animation states, and tile maps.
In Chapter 5, we extend the previous concepts to 3D to create "3D Mini Golf" and learn about mesh, lighting, camera control, etc.
Chapter 6, "Infinite Flyer," continues our exploration of 3D development, covering dynamic content, procedural generation, and other 3D techniques.
Chapter 7 explores additional topics and resources that may be helpful to know.
Finally, for Korean readers, we have included an appendix with a description of the Advanced Engine Editor menu.
By the time we finish our final project, we will be able to actually develop and implement games and game systems using Godo 4.
Beginners looking to start their own development journey can easily learn game development skills and go on to create their own games, while teams considering using a free game engine and experienced developers can realize their vision with the powerful and customizable Godo engine.
I look forward to seeing many advanced engine projects that progress to production in the future.
