Module Two

Module Two ยท Game Development with Unity

๐Ÿงฑ Module Two ยท Game Objects and Components


๐Ÿ“– Module Introduction

Hello, future game developer! In Module One, we learned the basics of Unity โ€” what it is, how to install it, and how to use the interface. We learned about the Scene, Game, Hierarchy, Project, and Inspector panels. Now it is time to start building.

In this module, we will learn about Game Objects and Components. Game Objects are the things you see in your game โ€” like characters, trees, and coins. Components are the features that make them work โ€” like movement, colour, and behaviour. By the end of this module, you will be able to create and control objects in your game world.

๐ŸŽฏ Learning Objectives

  • Understand what Game Objects are.
  • Learn about Components and how they add functionality.
  • Learn about Transform โ€” position, rotation, and scale.
  • Learn about Prefabs โ€” reusable game objects.
  • Create and manipulate objects in the Scene.

๐Ÿ“š Warm-up Story ยท Tunde's First Character

Tunde is a young game developer in Abuja. He wanted to create a character for his game. He opened Unity and created a Game Object โ€” a simple cube. He was excited to see it in the Scene.

But the cube was just a shape. It didn't do anything. He learned about Components. He added a Rigidbody component to make it fall with gravity. He added a script to make it move. The cube came to life.

Tunde then turned his cube into a Prefab so he could use it again in other levels. He was proud of his first character. He learned that Game Objects and Components are the building blocks of every game.

๐Ÿงฉ Main Lessons

Lesson 1 ยท What is a Game Object?

Definition: A Game Object is any object in your game โ€” a character, a coin, a tree, or a light.

Why important: Everything in your game is a Game Object.

Simple explanation: A Game Object is like a toy that you place in your game world.

Real-life example: A character in a game is a Game Object.

School example: A student places objects in a scene.

Home example: A toy on a shelf.

Nigerian example: A player character in a Nigerian game.

    Z = forward/backward
            

Mini summary: Position places an object in the world.


Lesson 6 ยท Rotation

Definition: Rotation controls which direction the object is facing.

Why important: You need objects to face the right way.

Simple explanation: It's like turning your head.

Real-life example: A person turns to look at something.

School example: A chair faces the teacher.

Home example: A TV is turned toward the sofa.

Nigerian example: A character faces the enemy.

Illustration:

    Rotation:
    X = tilt up/down
    Y = turn left/right
    Z = roll
            

Mini summary: Rotation controls the direction an object faces.


Lesson 7 ยท Scale

Definition: Scale controls the size of the object.

Why important: You need objects to be the right size.

Simple explanation: It's like making something bigger or smaller.

Real-life example: A poster can be small or large.

School example: A globe can be scaled up or down.

Home example: A photo can be enlarged or reduced.

Nigerian example: A character can be scaled to fit.

Illustration:

    Scale:
    X = width
    Y = height
    Z = depth
            

Mini summary: Scale controls the size of the object.


Lesson 8 ยท Prefabs

Definition: A Prefab is a reusable Game Object. You can save it and use it many times.

Why important: Prefabs save time and keep things consistent.

Simple explanation: Like a stamp โ€” you use it to make many copies.

Real-life example: A coin prefab can be placed many times.

School example: A student uses a template for posters.

Home example: A cookie cutter makes many cookies.

Nigerian example: A character prefab is used in many levels.

Illustration:

Module Three ยท Game Development with Unity

๐Ÿ’ป Module Three ยท Introduction to C# Scripting


๐Ÿ“– Module Introduction

Hello, future game developer! In Module Two, we learned about Game Objects and Components. We learned how to create and control objects in the scene. Now it is time to bring them to life with code.

In this module, we will learn the basics of C# (pronounced "C sharp"), the programming language used in Unity. We will write simple scripts to make our Game Objects move, jump, and interact. By the end of this module, you will be able to write your own scripts and make your game interactive.

๐ŸŽฏ Learning Objectives

  • Understand what C# is and why it is used in Unity.
  • Learn the basic structure of a C# script.
  • Learn about variables, functions, and events.
  • Write a simple script to move a Game Object.
  • Attach a script to a Game Object.

๐Ÿ“š Warm-up Story ยท Chioma's Moving Player

Chioma is a young game developer in Enugu. She had built a scene with a player character. But her player just sat there. It didn't move. It didn't do anything. She knew she needed to write code.

She opened Visual Studio and wrote her first C# script. She used a function called Update() to move the player forward. She attached the script to her player. When she pressed Play, the player moved! She was amazed.

Chioma learned that C# is the magic behind every game. It makes things move, jump, and react. She continued learning and soon could create complex behaviours.

๐Ÿงฉ Main Lessons

Lesson 1 ยท What is C#?

Definition: C# is a programming language used to write code for Unity games.

Why important: C# is what makes your game interactive.

Simple explanation: C# is like a set of instructions you give to your game.

Real-life example: A recipe is a set of instructions for cooking.

School example: A student writes instructions for a robot.

Home example: A parent writes a to-do list.

Nigerian example: A developer writes code for a Nigerian game.

Illustration:

    +----------------------+
    |  C# = Instructions   |
    |  for your game       |
    |  โ†’ Move             |
    |  โ†’ Jump             |
    |  โ†’ Collect          |
    +----------------------+
            

Mini summary: C# is the language used to control your game.


Lesson 2 ยท Creating a Script

Definition: A script is a file that contains C# code. You attach it to a Game Object.

Why important: Scripts give behaviour to objects.

Simple explanation: A script is like a set of rules for an object.

Real-life example: A script for a character tells it how to move.

School example: A student writes a script for a robot.

Home example: A parent creates a chore list.

Nigerian example: A developer writes a script for a player.

Illustration:

    Create a Script:
    1. Right-click in Project panel
    2. Choose Create โ†’ C# Script
    3. Name it "PlayerMovement"
    4. Double-click to open
            

Mini summary: A script is a file of code that controls an object.


Lesson 3 ยท The Script Structure

Definition: A C# script has a basic structure: using statements, a class, and methods.

Why important: This structure is the same for every script.

Simple explanation: It's like a template that you fill in.

Real-life example: A letter has a structure: greeting, body, closing.

School example: An essay has an introduction, body, and conclusion.

Home example: A recipe has ingredients and steps.

Nigerian example: A developer follows the same script structure.

Illustration:

    Script Structure:
    using UnityEngine;

    public class PlayerMovement : MonoBehaviour
    {
        // Variables go here
        void Start() { }
        void Update() { }
    }
            

Mini summary: All scripts have a similar structure.


Lesson 4 ยท Variables

Definition: A variable is a container that stores a value โ€” like a number or a word.

Why important: Variables store information that your script uses.

Simple explanation: Like a box that holds something.

Real-life example: A score variable stores the player's score.

School example: A grade variable stores a student's grade.

Home example: A grocery list variable stores items.

Nigerian example: A speed variable stores how fast a player moves.

Illustration:

    Variables:
    int score = 0;
    float speed = 5f;
    string name = "Player";
            

Mini summary: Variables store information.


Lesson 5 ยท Functions (Methods)

Definition: A function is a block of code that performs a specific task.

Why important: Functions organise your code and make it reusable.

Simple explanation: Like a recipe step that does one thing.

Real-life example: A function to move a player.

School example: A function to calculate the average of grades.

Home example: A function to clean a room.

Nigerian example: A function to jump when the player presses a button.

Illustration:

    Functions:
    void Start() { }
    void Update() { }
    void Jump() { }
            

Mini summary: Functions perform specific tasks.


Lesson 6 ยท The Start Function

Definition: The Start() function runs once when the game begins.

Why important: It is used for setup, like initialising variables.

Simple explanation: It's what happens at the beginning.

Real-life example: Turning on a game console.

School example: Setting up a classroom before class.

Home example: Setting the table before dinner.

Nigerian example: Initialising a player's health at the start.

Illustration:

    void Start()
    {
        // Runs once at start
        Debug.Log("Game Started!");
    }
            

Mini summary: Start runs once when the game begins.


Lesson 7 ยท The Update Function

Definition: The Update() function runs every frame of the game.

Why important: It is used for continuous actions like movement.

Simple explanation: It's what happens constantly.

Real-life example: Breathing is continuous.

School example: A teacher checks attendance every day.

Home example: Checking the time constantly.

Nigerian example: Moving a player every frame.

Illustration:

    void Update()
    {
        // Runs every frame
        transform.Translate(0, 0, speed * Time.deltaTime);
    }
            

Mini summary: Update runs continuously.


Lesson 8 ยท Moving a Game Object

Definition: You can move a Game Object by changing its position in the Update() function.

Why important: This is how you make characters move.

Simple explanation: You tell the object to move forward every frame.

Real-life example: A car moving forward.

School example: A student walking to class.

Home example: A fan spinning.

Nigerian example: A player moving in a game.

Illustration:

    // Move forward
    transform.Translate(Vector3.forward * speed * Time.deltaTime);
            

Mini summary: Move objects by changing their position.


Lesson 9 ยท Attaching a Script

Definition: You attach a script to a Game Object by dragging it onto the object or adding it as a component.

Why important: This is how you give behaviour to objects.

Simple explanation: You put the script on the object you want to control.

Real-life example: Putting a remote control on a toy.

School example: Attaching a note to a project.

Module Four

Module Four ยท Game Development with Unity

โšก Module Four ยท Physics and Collisions


๐Ÿ“– Module Introduction

Hello, future game developer! In Module Three, we learned about C# scripting. We learned how to write code to move and control Game Objects. Now it is time to make our game feel more real with physics and collisions.

Physics makes objects fall, bounce, and move like they do in the real world. Collisions happen when objects touch each other. In this module, we will learn how to add physics to our objects and detect when they collide. By the end of this module, you will be able to make objects interact with gravity, walls, and each other.

๐ŸŽฏ Learning Objectives

  • Understand what physics is in Unity.
  • Learn about Rigidbody and how it adds physics.
  • Learn about Colliders and how they detect collisions.
  • Learn about Triggers and how they detect overlap.
  • Write scripts to detect collisions and triggers.

๐Ÿ“š Warm-up Story ยท Kofi's Falling Ball

Kofi is a game developer in Accra. He wanted to create a game where a ball falls and bounces. He placed a ball in the scene, but it just floated in the air. It didn't fall. He knew he needed physics.

He added a Rigidbody component to the ball. Now it fell with gravity. He added a Collider to the ball and to the ground. When the ball hit the ground, it bounced. Kofi was thrilled. He then added a script to collect coins when the ball touched them. He learned that physics and collisions make games feel real.

๐Ÿงฉ Main Lessons

Simple explanation: Unity tells you when objects hit each other.

Real-life example: A player touches a coin and collects it.

School example: Two students bump into each other.

Home example: A glass hits a table.

Nigerian example: A character hits an enemy.

Illustration:

    Collision Detection:
    Object A โ†’ touches โ†’ Object B โ†’ event triggers
            

Mini summary: Collision detection tells you when objects touch.


Lesson 7 ยท OnCollisionEnter

Definition: OnCollisionEnter() is a function that runs when two objects with Colliders collide.

Why important: It lets you respond to collisions.

Simple explanation: It's like a doorbell that rings when someone touches the door.

Real-life example: A script that plays a sound when a ball hits a wall.

School example: A bell rings when a student enters the room.
