Introduction to GDScript

Welcome to the tutorial on GDScript, the primary scripting language used in Godot Engine! In this tutorial, we'll cover the basics of GDScript and how to add interactivity and logic to your Godot games.

What is GDScript?

GDScript is a high-level, dynamically typed scripting language specifically designed for use in Godot Engine. It is similar to Python in syntax and is optimized for ease of use and performance within the Godot environment. GDScript is the recommended scripting language for most Godot projects due to its simplicity and seamless integration with the engine's features.

Variables and Data Types

Like many programming languages, GDScript supports various data types such as integers, floats, strings, arrays, and dictionaries. Here's an example of declaring and initializing variables in GDScript:

var player_health = 100
var player_name = "Player1"

Control Flow

GDScript provides familiar control flow structures like if statements, for loops, and while loops for implementing logic in your games. Here's an example of an if statement in GDScript:

if player_health > 0:
    print("Player is alive!")
else:
    print("Player is dead!")

Functions and Methods

Functions and methods are used to encapsulate reusable blocks of code in GDScript. Here's an example of defining a function in GDScript:

func calculate_damage(damage_amount, defense):
    var damage_taken = damage_amount - defense
    return damage_taken

Object-Oriented Programming

GDScript supports object-oriented programming paradigms such as classes, inheritance, and polymorphism. Here's an example of defining a class in GDScript:

class Player:
    var health = 100
    var name = "Player1"

    func take_damage(damage_amount):
        health -= damage_amount

Conclusion

You've completed the introduction to GDScript. This tutorial covered the basics of GDScript, including variables and data types, control flow, functions and methods, and object-oriented programming concepts. With this knowledge, you can start writing scripts to add interactivity and logic to your Godot games.
