Whether you dream of building your own mobile game or want to start a freelancing career earning in PKR, this tutorial will guide you step-by-step.

Prerequisites

Before starting this Godot 4 tutorial, you should have:

• Basic understanding of programming concepts (variables, loops, functions)
• Familiarity with Python (helpful but not required)
• A computer (even low-spec laptops can run Godot)
• Willingness to practice and experiment

Optional but helpful:

• Basic math knowledge (coordinates, movement)
• Interest in gaming or storytelling

Core Concepts & Explanation

Scene and Node System (The Heart of Godot)

Godot works on a scene and node system, which is very different from traditional engines.

• A Node is a basic building block (like Player, Camera, Light)
• A Scene is a collection of nodes

Think of it like this:

A game = multiple scenes
A scene = multiple nodes

Example:

• Player (Node2D)
• Sprite (visual)
• CollisionShape2D (physics)

You combine these to create a player character.

GDScript Basics (Beginner-Friendly Coding)

Godot uses GDScript, which looks very similar to Python.

Example:

extends Node2D

func _ready():
    print("Game Started")

func _process(delta):
    print("Game Running")

Line-by-line explanation:

• extends Node2D → This script is attached to a 2D node
• func _ready() → Runs once when the scene starts
• print("Game Started") → Displays message in console
• func _process(delta) → Runs every frame
• delta → Time between frames (used for smooth movement)

Signals and Events (Communication System)

Signals are used to make nodes communicate.

Example:

• Button clicked → Player moves
• Enemy defeated → Score increases

Example code:

func _on_button_pressed():
    print("Button Clicked")

Explanation:

• _on_button_pressed() → Function triggered by signal
• print() → Shows output

Practical Code Examples

Example 1: Player Movement in 2D

Let’s create a simple player movement system.

extends CharacterBody2D

var speed = 200

func _process(delta):
    var direction = 0
    
    if Input.is_action_pressed("ui_right"):
        direction += 1
    if Input.is_action_pressed("ui_left"):
        direction -= 1
    
    velocity.x = direction * speed
    move_and_slide()

Line-by-line explanation:

• extends CharacterBody2D → Physics-based player
• var speed = 200 → Player movement speed
• _process(delta) → Runs every frame
• var direction = 0 → Stores movement direction
• Input.is_action_pressed() → Checks key press
• direction += 1 → Move right
• direction -= 1 → Move left
• velocity.x = direction * speed → Apply movement
• move_and_slide() → Moves player with physics

💡 Real-world example: Ahmad is building a simple platformer game where the player moves left and right.

Example 2: Real-World Application (Score System)

Let’s create a scoring system for a coin collection game.

extends Node

var score = 0

func add_score():
    score += 10
    print("Score: ", score)

Line-by-line explanation:

• extends Node → Basic node
• var score = 0 → Initial score
• add_score() → Function to increase score
• score += 10 → Adds 10 points
• print() → Displays updated score

💡 Example: Fatima creates a game where collecting coins increases score in PKR-style rewards.

Common Mistakes & How to Avoid Them

Mistake 1: Forgetting to Use delta

❌ Wrong:

position.x += 5

Problem: Movement speed depends on FPS.

✅ Correct:

position.x += 200 * delta

Fix:

• Always use delta for smooth movement.

Mistake 2: Not Connecting Signals Properly

❌ Problem:
Button does nothing when clicked.

✅ Fix:

• Select node → Go to “Signals” → Connect to script

Example:

func _on_button_pressed():
    print("Clicked")

Mistake 3: Wrong Node Type

Using Node2D instead of CharacterBody2D for movement.

✅ Fix:

• Use correct node type for physics

Practice Exercises

Exercise 1: Move Player Up and Down

Problem:
Modify movement code to allow vertical movement.

Solution:

extends CharacterBody2D

var speed = 200

func _process(delta):
    var direction = Vector2.ZERO
    
    if Input.is_action_pressed("ui_right"):
        direction.x += 1
    if Input.is_action_pressed("ui_left"):
        direction.x -= 1
    if Input.is_action_pressed("ui_up"):
        direction.y -= 1
    if Input.is_action_pressed("ui_down"):
        direction.y += 1
    
    velocity = direction * speed
    move_and_slide()

Explanation:

• Vector2.ZERO → 2D direction
• direction.x → Horizontal movement
• direction.y → Vertical movement
• velocity → Combined movement

Exercise 2: Create a Health System

Problem:
Create a system where player health decreases when hit.

Solution:

extends Node

var health = 100

func take_damage():
    health -= 10
    print("Health: ", health)

Explanation:

• health = 100 → Starting health
• take_damage() → Called when hit
• health -= 10 → Reduce health
• print() → Show remaining health
