How to make a cookie clicker game on Scratch?

Creating a Cookie Clicker Game on Scratch

Introduction

The Cookie Clicker game is a popular online game that has been around for several years. It’s a simple yet addictive game where players click on a cookie to earn points, which can be used to buy upgrades and increase their cookie production. In this article, we’ll guide you through the process of creating a Cookie Clicker game on Scratch.

Setting Up Scratch

Before we begin, make sure you have Scratch installed on your computer. If you don’t have it, you can download it from the official Scratch website.

Creating a New Project

To start creating a Cookie Clicker game, follow these steps:

• Open Scratch and create a new project by clicking on the "File" menu and selecting "New Project".
• Choose a project name and click "Create".
• Select the "Scratch" template and click "Create".

Defining the Game’s Variables

In the Scratch editor, you’ll see a series of boxes and sliders that represent the game’s variables. These variables control the game’s behavior and can be adjusted to create different gameplay experiences.

• Cookie Count: This variable represents the number of cookies the player has. It starts at 0 and increases by 1 each time the player clicks on a cookie.
• Cookie Production: This variable represents the rate at which cookies are produced. It starts at 0 and increases by 1 each time the player clicks on a cookie.
• Upgrade Cost: This variable represents the cost of each upgrade. It starts at 0 and increases by 1 each time the player clicks on a cookie.

Creating the Cookie Clicker Game

Now that we have our variables defined, let’s create the game’s logic.

• Cookie Click Event: This event is triggered when the player clicks on a cookie. It increments the Cookie Count variable by 1.
• Upgrade Event: This event is triggered when the player clicks on an upgrade. It increments the Cookie Production variable by 1.
• Upgrade Cost Event: This event is triggered when the player clicks on an upgrade. It increments the Upgrade Cost variable by 1.

Here’s some sample code to get you started:

// Variables

var cookieCount = 0;

var cookieProduction = 0;

var upgradeCost = 0;



// Cookie Click Event

function cookieClick() {

  cookieCount++;

}



// Upgrade Event

function upgradeClick() {

  cookieProduction++;

}



// Upgrade Cost Event

function upgradeCostClick() {

  upgradeCost++;

}

Creating the Cookie Production System

The cookie production system is responsible for generating cookies based on the Cookie Production variable.

• Cookie Generation: This function generates a random number between 0 and 1. If the number is less than the Cookie Production variable, it generates a cookie.
• Cookie Generation with Upgrade: This function generates a random number between 0 and 1. If the number is less than the Cookie Production variable and the Upgrade Cost variable is greater than 0, it generates a cookie.

Here’s some sample code to get you started:

// Cookie Generation

function cookieGeneration() {

  var cookie = Math.random() < cookieProduction ? 1 : 0;

  return cookie;

}



// Cookie Generation with Upgrade

function cookieGenerationWithUpgrade() {

  var cookie = Math.random() < cookieProduction && upgradeCost > 0 ? 1 : 0;

  return cookie;

}

Creating the Cookie Clicker UI

The cookie clicker UI is responsible for displaying the game’s information and allowing the player to interact with the game.

• Cookie Count Display: This display shows the current Cookie Count variable.
• Cookie Production Display: This display shows the current Cookie Production variable.
• Upgrade Cost Display: This display shows the current Upgrade Cost variable.
• Upgrade Button: This button allows the player to click on an upgrade to increase the Cookie Production variable.
• Upgrade Cost Button: This button allows the player to click on an upgrade to increase the Upgrade Cost variable.

Here’s some sample code to get you started:

// Cookie Count Display

function cookieCountDisplay() {

  var text = "Cookie Count: " + cookieCount;

  return text;

}



// Cookie Production Display

function cookieProductionDisplay() {

  var text = "Cookie Production: " + cookieProduction;

  return text;

}



// Upgrade Cost Display

function upgradeCostDisplay() {

  var text = "Upgrade Cost: " + upgradeCost;

  return text;

}



// Upgrade Button

function upgradeButton() {

  return "Click to upgrade";

}



// Upgrade Cost Button

function upgradeCostButton() {

  return "Click to upgrade";

}

Adding the Cookie Clicker UI to the Game

To add the cookie clicker UI to the game, follow these steps:

• Create a new sprite: Create a new sprite by clicking on the "Sprites" menu and selecting "New Sprite".
• Add the cookie clicker UI: Drag and drop the cookie clicker UI sprites onto the sprite.
• Configure the UI: Configure the UI by setting the Cookie Count, Cookie Production, and Upgrade Cost variables.

Here’s some sample code to get you started:

// Add the cookie clicker UI to the game

function addCookieClickerUI() {

  var cookieCountSprite = new Sprite();

  cookieCountSprite.x = 100;

  cookieCountSprite.y = 100;

  cookieCountSprite.width = 50;

  cookieCountSprite.height = 50;

  cookieCountSprite.color = color(255, 0, 0);

  cookieCountSprite.text = "Cookie Count: 0";

  game.addSprite(cookieCountSprite);



  var cookieProductionSprite = new Sprite();

  cookieProductionSprite.x = 200;

  cookieProductionSprite.y = 100;

  cookieProductionSprite.width = 50;

  cookieProductionSprite.height = 50;

  cookieProductionSprite.color = color(0, 255, 0);

  cookieProductionSprite.text = "Cookie Production: 0";

  game.addSprite(cookieProductionSprite);



  var upgradeCostSprite = new Sprite();

  upgradeCostSprite.x = 300;

  upgradeCostSprite.y = 100;

  upgradeCostSprite.width = 50;

  upgradeCostSprite.height = 50;

  upgradeCostSprite.color = color(0, 0, 255);

  upgradeCostSprite.text = "Upgrade Cost: 0";

  game.addSprite(upgradeCostSprite);

}

Testing the Game

To test the game, follow these steps:

• Run the game: Run the game by clicking on the "Run" button.
• Click on cookies: Click on cookies to earn points.
• Upgrade: Click on upgrades to increase the Cookie Production variable.
• Check the UI: Check the UI to see if the game is working correctly.

Here’s some sample code to get you started:

// Run the game

function runGame() {

  game.run();

}

Conclusion

Creating a Cookie Clicker game on Scratch is a fun and rewarding experience. By following these steps, you can create a game that is both simple and addictive. Remember to experiment with different variables and UI elements to create a game that is unique and engaging. Happy coding!
