Learn Godot - Pre-Requisite Skills & Environment Setup

#Introduction

Welcome to the Learn Godot series! This series will take you from zero to a game developer with Godot — a lightweight, cross-platform, royalty-free open-source game engine — starting from environment setup all the way to production-grade. There are 23 sequential episodes in total, so reading every episode in order will build up mastery layer by layer.

Episode 0 is the foundation: before diving into code and scenes, let's make sure your skills and environment are ready. It's like preparing your workbench before building furniture — cheap at the start, very expensive to adjust halfway through. This episode's roadmap: basic programming and game logic skills, vector math concepts, the asset pipeline, the software you must install, and minimum hardware specifications.

#Basic Skills You Must Master

#Basic Programming

Godot uses GDScript, which is very similar to Python, so you don't need a C++ or Java background. What you must master are the four programming foundations: variables, conditionals, loops, and functions. Without these four, the scripting episodes ahead will feel like reading a foreign language. A small example in GDScript:

The four programming foundations in GDScript

var skor: int = 0
 
func tambah_poin(jumlah: int) -> void:
    skor += jumlah
 
func cek_level() -> String:
    if skor >= 100:
        return "Level 2"
    elif skor >= 50:
        return "Level 1"
    return "Level 0"
 
for i in range(3):
    print("Iterasi ", i)

Notice: variables are declared with var, types are written after a colon, and functions use the func keyword. We'll dissect all of this in detail in episode 5, but understanding the basic patterns now will make you much more comfortable later.

#Basic Game Logic

Games, regardless of genre, are built from three core concepts:

• Game loop: a cycle that keeps running — read input, update logic, render frame — repeating dozens to hundreds of times per second. Godot runs this loop itself; your job is only to fill in the update logic.
• Event handling: games are reactive. The player presses a button, an enemy hits a wall, an item is picked up — these are all events that trigger responses. Godot abstracts this through signals (signal), which we'll learn about in episodes 2 and 5.
• Physics concepts: gravity, velocity, acceleration, and collision detection. You don't need to memorize formulas, just understand the intuition: velocity is the change of position over time, and acceleration is the change of velocity over time.

#Vector Math and Coordinate Systems

This concept might seem the most "intimidating," yet it's very simple. Any position on screen can be expressed as a pair of coordinates: x to the right and y down (in Godot 2D, the positive y axis points down, unlike school math). A vector is simply a set of numbers that describes a position, direction, or velocity.

Godot provides the Vector2 type for 2D and Vector3 for 3D. The key concepts you must understand:

• Vector addition: position plus displacement gives a new position.
• Vector scaling: multiplying a vector by a number speeds up or slows down movement.
• Vector length: distance, used for example in radius detection.

Example of vector operations in GDScript

posisi  = Vector2(100, 200)
gerak   = Vector2(10, 0)
posisi += gerak * kecepatan

#Asset Pipeline Basics

Games aren't just about code — there are assets: images, sounds, and animations. You need to understand the basic asset pipeline flow: creating assets in external tools, exporting them to formats Godot supports, then importing them into the project. For graphics, prepare with formats like PNG and WebP for sprites. For audio, get familiar with the WAV and OGG formats. For animation, be ready to import models from Blender or add animations directly in Godot.

#Software and Tools to Prepare

• Godot Engine — the core of this series. Download it from the official Godot website; version 4.x is the stable release we'll use throughout the series.
• Code editor or IDE — Godot already has a pretty good built-in script editor, but VS Code with the Godot Tools extension is a popular choice for code completion.
• Asset tools — an image editor like GIMP or Krita for graphics, audio tools like Audacity, and optionally Blender for 3D models.
• Git for version control — a must once you start getting serious. All our projects will be managed with Git.

Quick verification that Git is installed and configured:

git --version

git config --global user.name "Your Name"
git config --global user.email "email@example.com"

Godot can also be run from the terminal via its binary. After downloading and extracting it, try godot --version to make sure the binary is detected in PATH. This is useful because later we'll run projects via the command line for automated testing.

#Minimum Hardware Requirements

Godot is very resource-efficient, but there is still a lower bound. These are the recommended minimum specifications:

• Minimum 8GB RAM — the Godot editor itself only needs about 500MB, but the rest of the RAM is used by the operating system, browser, and the running project. For heavy 3D projects, 16GB is much more comfortable.
• Dual-core CPU — enough for 2D development and prototyping. Complex 3D rendering is where you'll feel the need for a faster CPU.
• 10GB+ storage — the Godot binary is small (around 50-100MB), but projects, assets, and export templates keep growing. Give yourself plenty of room.

#Conclusion

In this episode 0, you've laid the foundation for the entire series: the four programming foundations, basic game logic, vector math, the asset pipeline concept, the software to install, and minimum hardware specifications. If any skill still feels unfamiliar, don't panic — everything will be put into practice in the episodes ahead.

The key takeaways:

• GDScript is similar to Python, so focus your attention on variables, conditionals, loops, and functions.
• The game loop, event handling, and physics concepts are the basic logic of every game.
• Vector2 and Vector3 are the language of position and movement in Godot.
• Install Godot 4.x, your editor of choice, and Git before the next episode.
• Reasonable minimum hardware: 8GB RAM, a dual-core CPU, and 10GB of storage.

In the next episode, episode 1, we'll cover the history, background, and why Godot deserves to be your choice — from a personal project of two Argentine developers, the birth of Godot 1.0, to why this engine stands out compared to Unity and Unreal Engine. Make sure Godot is downloaded, because in episodes 2 and 3 we'll open the editor for the first time!
