Introduction

In this tutorial, we will learn how to create a spin the wheel game using Scratch. Scratch is a visual programming language that allows you to create interactive stories, games, and animations. The spin the wheel game is a popular game that involves spinning a wheel to win prizes or points. We will guide you through the process of setting up the project, coding the wheel rotation, customizing the wheel appearance, adding color conditions, broadcasting win and lose messages, creating backdrops for win and lose, making a 3D text effect, and adding final touches. By the end of this tutorial, you will have a fully functional spin the wheel game that you can customize and share with others.

Setting up the Project

The first step is to set up the project in Scratch. Open Scratch and create a new project. You can choose a background for your project or leave it blank. Next, click on the "Choose a sprite from library" button and select the wheel sprite. You can also upload your own custom sprite if you prefer. Set the x and y coordinates of the sprite to zero to position it at the center of the stage.

Uploading the Wheel Sprite

To upload the wheel sprite, click on the "Choose a sprite from file" button and select the wheel image file from your computer. Name the sprite "wheel" or choose any other title you prefer. The wheel sprite will be the main element of the spin the wheel game as it represents the wheel that will be spun to win prizes.

Coding the Wheel Rotation

Now, let's code the rotation of the wheel when the green flag is clicked. Go to the "Events" category and drag the "When flag clicked" block to the coding area. From the "Motion" category, drag the "Point in direction" block and set the direction to 90 degrees. Next, go to the "Operators" category and drag the "Pick random" block. Change the range of the random number to pick random 1 to 400. Add two of these blocks inside a "Repeat" loop from the "Control" category. This will make the wheel rotate randomly.

Customizing the Wheel Appearance

Now let's customize the appearance of the wheel. Click on the "Choose a sprite from library" button and select the brush tool. Set the color to black and the size to 53. Use the brush tool to draw the spin text in the middle of the wheel. Then, change the size to 47 and the color to white. Click on the rectangle tool and change the color to green. Draw 3x4 squares to create the segments of the wheel. Use the reshape tool to adjust the size and shape of the squares as needed. Duplicate the squares and change the color to white to create a contrast.

Creating the Spin Button

To create the spin button, go to the "Choose a sprite from library" button and select the paint tool. Zoom in using the scroll wheel or the zoom button. Change the color to black and write the word "spin" on the canvas. Use the select tool to click on the spin text and press "flip vertical" to mirror it. Name the sprite "spin" and position it at the top of the stage. Change the direction of the sprite to 65 degrees.

Adding Color Conditions

In the spin the wheel game, we want different colors of the wheel to represent different outcomes. Go to the wheel sprite and add a "Broadcast" block from the "Events" category. Name the message "rotate" or choose any other title you prefer. Add this block inside the repeat loop. Now, let's add color conditions to determine the outcome of the spin. Go to the "Sensing" category and drag the "Touching color?" block. Choose any color of the wheel. Duplicate this block for all the colors on the wheel. The conditions and colors may vary depending on the wheel image you are using.

Broadcasting Win and Lose Messages

To inform the player if they have won or lost, we need to broadcast win and lose messages. Right-click on the "Broadcast" block and duplicate it. Drag the duplicated block inside the color conditions that give more than zero points. Drag another "Broadcast" block inside the color conditions that give zero or less than zero points. You can customize the win and lose messages by modifying the broadcast blocks.

Creating Backdrops for Win and Lose

To create backdrops for when the player wins or loses, right-click on the backdrop icon and press duplicate. Change the text on the backdrop to "win" and "lose" respectively. You can choose any other titles for the backdrops if you prefer. In the "Events" category, add a "When green flag clicked" block and a "When I receive" block for both the win and lose messages. In the "Looks" category, add a "Switch backdrop to" block and select the win backdrop under the green flag block and the lose backdrop under the lose message block.

Making a 3D Text Effect

To create a 3D text effect, click on the "Choose a sprite from library" button and select the text tool. Change the color to black and choose a font if desired. Click on the stage and write your desired text. Drag the text slightly to the left of the middle point. Press "ctrl+c" and "ctrl+v" or copy and paste the text. Change the color of the second text to a different color. Drag the second text to the middle. Right-click on the backdrop icon and duplicate it. Change the text from "you win" to "try again". Name the backdrops based on your preferred titles.

Adding Final Touches and Testing

To add final touches, go to the stage and click on the "Convert to bitmap" button. Choose the color you want, like orange, and click on the fill tool. Click on the stage to fill it with the selected color. Convert the backdrop back to vector. Test your project by clicking the green flag and spinning the wheel. Check if the win and lose messages are displayed correctly and the backdrops are switched accordingly. Make any necessary adjustments or customizations based on your preferences.
