Setting Up GDScript IDE

Before we can start coding in GDScript, we need to set up our development environment. Here’s how you can do that:

# Step 1: Download Godot Engine
Download the latest version of Godot engine from

# Step 2: Extract Archive
Extract the downloaded archive. This will create a new folder.

# Step 3: Open Godot
Run the Godot executable. This will open the project manager.

In the project manager, you create, remove, import, or run projects. For this tutorial, let’s create a new project.

# Step 4: Create New Project
Click the 'New Project' button, choose a path for your project, and give it a name.

# Step 5: Setup Project
Click 'Create & Edit'. This opens the main editor where you'll be coding.

Writing Your First GDScript Code

To write your GDScript code, Godot provides a script editor right inside the engine. Here are some basic steps to start coding:

# Step 1: Open Script Editor
In the main editor interface, click on 'Script' in the top menu. The script editor will open up.

# Step 2: Create New Script
Click on 'File' > 'New Script'. In the dialog box that opens, give your script a name and save it.

Now that we’ve created a new script, let’s write a simple “Hello, World!” program:

extends Node

func _ready():
    print("Hello, World!")

In this code snippet:

  • extends Node: This line tells Godot that our script should inherit from the Node class.
  • func _ready(): This is a function that Godot automatically calls when a node and its children have entered the scene and are ready.
  • print(“Hello, World!”): This line simply prints the string “Hello, World!” to the output console.

To run your script, you’ll need to attach it to a node. In Godot, almost everything is a node. They are used to manage game logic, display graphics, play sound, and much more.

# Step 3: Create Object
Select the '2D Scene' from the main menu to create a new 2D scene.

# Step 4: Attach Script
In the Scene dock, click on '+', name your node and click on 'Create'. then choose the 'Attach Script' button in the top right of the scene dock. In the pop-up window, select your script and click 'Open'.

There, we’ve covered the basics of setting up GDScript IDE and writing your very first script. In the next part, we’ll delve deeper into the GDScript language and explore more advanced topics.

Exploring GDScript Basics

Now that we have an understanding of how to use the GDScript Integrated Development Environment, let’s delve deeper into the peculiarities of the GDScript language.

Data Types

As with most programming languages, GDScript uses numerous data types, including integers, floats, booleans, strings, and arrays. Here are examples of how to use each of these:

var my_int = 10
var my_float = 3.14159
var my_bool = true
var my_string = "Hello, GDScript!"
var my_array = [1, 2, 3, 4, 5]

In GDScript, the ‘var’ keyword is used to declare a variable.


GDScript supports a variety of operators for performing operations on its data types. These include arithmetic, comparison, and logical operators, among others. To illustrate, let’s combine these data types and operators to perform operations:

var a = 5
var b = 10

var sum = a + b
var diff = a - b
var product = a * b
var quotient = a / b

print(sum, diff, product, quotient)

Control Flow

GDScript provides different control flow statements to alter the flow of execution. These include “if”, “else”, “elif”, and loops like “for” and “while”. Let’s look at some examples:

# If Statement
var x = 10

if x > 5:
 print("x is greater than 5")

# For Loop
for i in range(5):
 print("i is: ", i)
# While Loop
var count = 0

while count < 5:
 print("count is: ", count)
 count += 1

Here, the “if” statement checks whether x is greater than 5, the “for” loop prints numbers from 0 to 4, and the “while” loop keeps printing and incrementing the “counter” value until it reaches 5.


A function is a block of code that performs a particular task and can be reused throughout your program. In GDScript, functions are defined using the “func” keyword. For example:

func greet(name):
 print("Hello, " + name + "!")

# Call the function

In this code snippet, a function named “greet” is created which accepts a single argument “name”. The function prints a greeting using the argument. It is then called with the string “GDScript” as an argument.

As you can see, GDScript offers a vast variety of capabilities while maintaining simplicity and readability. Getting comfortable with GDScript will provide you with a solid foundation for your Godot game development journey. Next, we’ll explore advanced gameplay mechanics and how to implement them using GDScript.

Diving Deeper into GDScript

As we further explore the world of GDScript, let’s take a look at more advanced features of the language that you will find helpful while developing games with Godot.


One of the most powerful aspects of Godot and GDScript is the signal system. Signals allow nodes to communicate with each other without needing to understand the inner workings of the connected node. They basically act like an emission and reception system.

Here is a simple example of creating and emitting a signal:

# Create a signal named 'health_changed'
signal health_changed

# Emit the signal with a message
emit_signal("health_changed", "Player health changed")

The signal ‘health_changed’ is declared at the top of the script using the ‘signal’ keyword. It can then be emitted anywhere in the script using ’emit_signal’.

Classes and Inheritance

GDScript is fully object-oriented and uses classes for scripts. Every script implicitly inherits from “Object”. However, different behaviors are provided by different nodes which classes can inherit from.

For example, let’s declare a simple class that models an enemy:

class_name Enemy
extends Node2D

var health = 100

func take_damage(damage):
    health -= damage

Each instance of the class “Enemy” would have a health property and a take_damage() method that changes the health by the passed amount in the argument.

But what if you needed different types of enemies? This is where inheritance comes in. Let’s create a Boss Enemy who will inherit from our original Enemy:

extends Enemy

var armor = 50

func take_damage(damage):
    health -= (damage - armor)

The “Boss” effectively inherits the attributes and functionality of “Enemy” but overrides the ‘take_damage’ function to incorporate the ‘armor’ attribute into the damage calculation.

Instancing Scenes

In Godot, everything is a scene. A scene can be a character, a button, a level, or any other kind of object. Each of these scenes can be easily instanced in others, resulting in reusability and organization.

For example, let’s instance an ‘Enemy’ scene into our ‘Game’ scene:

onready var enemy_scene = load("res://Enemy.tscn")

func start_game():
    var enemy_instance = enemy_scene.instance()

Here, ‘Enemy.tscn’ is loaded as the scene, and the instance of it is added as a child of the current scene (‘Game’) using the ‘add_child’ function.

Incorporating these advanced concepts in your GDScript knowledge inventory will allow you to develop complex games and applications with Godot. Now that you have a strong foundation of GDScript, we’re excited to see what you’ll create. Remember, keep exploring and keep coding!
