How to Make 3D in Scratch?
Scratch is a free, web-based software developed by MIT that allows users to create interactive, 3D stories, games, and animations. It’s an excellent tool for learning programming concepts and exploring 3D graphics. In this article, we’ll guide you through the process of making 3D in Scratch.
Getting Started
Before we dive into the tutorial, let’s cover some basics.
- What is Scratch?: Scratch is a software that lets you create interactive stories, games, and animations using block-based programming. It’s designed for kids and adults alike, but it’s also a great learning tool for anyone interested in programming.
- What can I make in Scratch?: You can create anything from simple animations to complex games, stories, and interactive simulations. You can also create interactive 3D models and animations.
Basic Scratch Tools
Before we start creating 3D, let’s familiarize ourselves with some basic Scratch tools.
- Blocks: Scratch uses a block-based programming language. Each block represents a small program that performs a specific task. You can think of blocks as LEGO bricks, but instead of building physical structures, you’re building programs.
- Properties: Each block has properties that can be modified. These properties include name, description, and line number. For example, you can set the property "name" to "Shape" and "description" to "3D Shape".
- Variables: Variables store values that can be used in programs. You can think of variables as containers that hold values.
Creating a 3D Character
To create a 3D character in Scratch, we’ll use some basic blocks. Here’s a step-by-step guide:
- Create a new document: Go to File > New > Scratch to create a new document.
- Open the Block Editor: In the Scratch interface, click on Block Editor to open the block editor.
- Add blocks: Drag and drop the following blocks into the block editor:
- Circle: To create a circle, drag the Circle block onto the canvas.
- Point: To create a point, drag the Point block onto the canvas.
- Line: To create a line, drag the Line block onto the canvas.
- Text: To add text, drag the Text block onto the canvas.
- Create a shape: To create a 3D shape, drag the Shape block onto the canvas. We’ll use the Cube block for this example.
- Add properties: Click on the Cube block and set its properties:
- Name: Set the property to "Cube".
- Description: Set the property to "3D Cube".
- Size: Set the property to "Size 1".
- Create a face: To create a face, drag the Point block onto the canvas. Set its properties:
- Name: Set the property to "Face".
- Description: Set the property to "3D Face".
- Size: Set the property to "Size 1".
- Color: Set the property to "Color 1".
- Add texture: To add texture, drag the Image block onto the canvas. Set its properties:
- Name: Set the property to "Texture".
- Description: Set the property to "3D Texture".
- Image: Set the property to "Add image to text".
Assembling the Character
Now that we have our basic shape, we can start assembling the character. Here’s a step-by-step guide:
- Create a new shape: Create a new shape by dragging the Shape block onto the canvas.
- Add a face: Add a face to the shape by dragging the Point block onto the shape.
- Add a body: Add a body to the shape by dragging the Cube block onto the shape.
- Add limbs: Add limbs to the body by dragging the Point block onto the body.
- Add a hat: Add a hat to the head by dragging the Shape block onto the head.
- Add texture: Add texture to the character by dragging the Image block onto the character.
Adding Light and Shadows
To add light and shadows to our character, we’ll use some additional blocks.
- Create a light source: Create a light source by dragging the Light block onto the canvas.
- Create a shadow: Create a shadow by dragging the Shape block onto the light source.
- Add shading: Add shading to the character by dragging the Paint block onto the character.
Putting it all Together
Here’s a complete example of a 3D character in Scratch:
// Create a new document
Create New Document
// Open the Block Editor
Block Editor Open
// Add blocks
Circle <<Size 1>>,
Point <<Size 1>>,

Color <<"Color 1">>,Tips and Tricks
- Experiment with different blocks: Don’t be afraid to experiment with different blocks and properties to create unique characters.
- Use the canvas to your advantage: Use the canvas to create complex shapes and 3D models.
- Use images to add texture: Use images to add texture and detail to your characters.
Conclusion
Making 3D in Scratch is a fun and creative process. By following the steps outlined in this article, you can create your own 3D characters and models. Remember to experiment with different blocks and properties to create unique characters and models. Happy creating!
