🧱 Instantiation & Objects

Creating actual game objects inside your GameLevel configuration

What Is Instantiation?

Instantiation means creating a real, usable object from a class.

A class is just a blueprint.
Instantiation is the moment you build something from that blueprint.

Example:

const player = new Player("Ironhook");

Here:

• Player is the class (the blueprint)
• new Player(...) instantiates a new object
• player is the actual object you can use in the game

---

What Is an Object?

An object is the thing created from a class.

It has:

• Properties (data it stores)
• Methods (things it can do)

Example:

player.name      // property
player.attack()  // method

Objects are the “living” pieces of your game world.

Why Instantiation Matters in Games

Games rely on many objects:

• The player
• Enemies
• Platforms
• Items
• Hazards
• Projectiles
• NPCs

Each one is created (instantiated) from a class.

Without instantiation, your game would have no actual entities — only blueprints.

Instantiating Objects in a GameLevel

In many game engines or custom frameworks, a GameLevel has a configuration section where you create all the objects that should appear in that level.

Example:

class GameLevel {
    constructor() {
        this.objects = [
            new Player(100, 200),
            new Enemy(300, 200),
            new Platform(0, 350, 600, 40)
        ];
    }
}

What’s happening here?

• new Player(...) creates the player object
• new Enemy(...) creates an enemy
• new Platform(...) creates a platform
• All of them are stored in this.objects so the game engine can update and draw them

This is instantiation inside level configuration.

---

Why?

Understanding instantiation shows that you can:

• Build real objects from your classes
• Populate a game world with entities
• Organize objects inside a level or scene
• Use constructors and parameters correctly
• Structure your game logic cleanly

It’s a core part of object‑oriented game development.

Small Example (Simple & Clear)

class Pirate {
    constructor(name, x, y) {
        this.name = name;
        this.x = x;
        this.y = y;
    }
}

class GameLevel {
    constructor() {
        this.objects = [
            new Pirate("Ironhook", 100, 200),
            new Pirate("Silentscar", 300, 200)
        ];
    }
}

const level1 = new GameLevel();
console.log(level1.objects);

This demonstrates:

• A class (Pirate)
• Instantiation (new Pirate(...))
• Level configuration (objects array)
• A real level object (level1)
