4. Installing the Godot Engine 🚀
Before embarking on your grand adventure in game development, you first need to install the Godot Engine. The best way to get Godot is to use Git. First, clone the official GitHub repository using the following command:
git clone https://github.com/godotengine/godot.git
This step will create a local copy stored in the current folder. To speed up the download and save disk space, you can add the --depth 1 parameter, resulting in a shallow clone with only the latest commits, omitting the complete history:
git clone https://github.com/godotengine/godot.git --depth 1
✔️ If you want to download a stable version, you can visit the release page and select the link for the version you need. For example, to clone the stable branch 4.3, you can use the following command:
git clone https://github.com/godotengine/godot.git -b 4.3
If you’d like to get the fixed version 4.3-stable, you can use this command:
git clone https://github.com/godotengine/godot.git -b 4.3-stable
🛠️ Once the cloning is complete, if you want to switch to a specific commit, you can use the following command:
cd godot
git checkout <commit_hash>
After cloning, the next step is to compile Godot; this step is crucial! You will need to follow the build guide for your target platform.
5. Code Examples and Their Usage Scenarios 📝
Create Your First Script 👶
In Godot, the primary language for coding is GDScript. Let’s take a look at how to create a simple “Hello, world!” script:
# This is a simple greeting script that extends the Node class
extends Node
func _ready():
print("Hello, world!") # Prints Hello, world! when the node is ready
✨ In the above code, extends Node indicates that this script extends a basic Node type. _ready() is a built-in function that is called when this node is added to the scene and all its child nodes are ready. Therefore, we can use the print function here to output information, verifying that our code works correctly.
Player Input Listening 🎮
If you want players to interact with your game, such as moving a character by pressing keys, you can utilize the following code:
# Move player when the "up" key is pressed
extends KinematicBody2D
var speed = 200 # Define movement speed
func _process(delta):
var motion = Vector2.ZERO # Initialize the motion vector
if Input.is_action_pressed("ui_up"):
motion.y -= 1 # If the up key is pressed, decrease y value to move the character up
if Input.is_action_pressed("ui_down"):
motion.y += 1 # If the down key is pressed, increase y value to move the character down
motion = motion.normalized() * speed * delta # Normalize the motion vector and calculate actual movement
move_and_collide(motion) # Move and check for collisions using the defined motion vector
🔄 The move_and_collide() function allows the character to move at the specified speed while checking for collisions during movement. The motion.normalized() ensures that the speed remains consistent even when moving in different directions.
Using Signals 📡
Signals are a powerful way to handle events in Godot; here’s how to use signals in code:
# Connect a signal in the editor
extends Button
func _on_Button_pressed():
print("Button was pressed!") # Prints a message when the button is pressed
# Or connect signals through code
func _ready():
self.connect("pressed", self, "_on_Button_pressed") # Connect the pressed signal of the button
🔗 Signals create a link between UI elements (like buttons) and game logic. In this example, when the button is pressed, the _on_Button_pressed() function is called, and a corresponding message will display in the console, allowing you to experiment with different logic!
Your First 2D Game 🕹️
To build a simple 2D game character, you can utilize the following code:
# Player movement and animation handling
extends KinematicBody2D
func _process(delta):
var velocity = Vector2.ZERO # Initialize velocity vector to zero
if Input.is_action_pressed("ui_right"):
velocity.x += 1 # Increase horizontal speed to right when right key is pressed
if Input.is_action_pressed("ui_left"):
velocity.x -= 1 # Decrease horizontal speed to left when left key is pressed
move_and_slide(velocity * speed) # Move using move_and_slide to handle sliding effect
🚀 This code example implements basic player movement logic, allowing users to control the character’s movements on the screen using the left and right keys. The move_and_slide() function manages movement while intelligently applying sliding against the ground and other objects.
Your First 3D Game 🌌
To create a simple 3D game, you can use the following code:
# Set up a simple 3D scene
extends Spatial
func _ready():
var player = Player3D.new() # Create a new 3D player object
add_child(player) # Add the player object to the scene tree
🌟 This code snippet creates a new 3D player object and adds it to the scene; the scene tree efficiently manages all your nodes, allowing you to manipulate elements in your game easily.
Exporting the Project 📦
Finally, after your game development is complete, you can use the Godot export functionality to publish your game across various platforms such as Linux, macOS, Windows, and mobile platforms! By following the build and deployment guidelines for your target platform, you can ensure that your game runs smoothly on all the devices you wish to support!
