Getting Started

If you’re new to Scratch, creating a 3D game may seem daunting. But don’t worry, we’ll guide you through the process step-by-step.

Creating a New Project

To get started, you’ll need to create a new project in Scratch. Here’s how:

  1. Go to the Scratch website (scratch.mit.edu) and log in or create a new account if you haven’t already.
  2. Click on the “Create” button in the top menu once you’re logged in. This will open the Scratch editor.
  3. Once you’re in the editor, you’ll see a blank canvas and a set of blocks on the left-hand side. You can use these blocks to create your game.

Understanding the Scratch Interface

Before you start coding your 3D game, it’s important to understand the Scratch interface. Here’s a quick rundown of the different parts of the interface:

  1. Stage: This is where your game will be displayed. You can add backgrounds and sprites to the stage to create your game.
  2. Sprites: These are the characters or objects in your game. You can add, delete, and modify sprites as needed.
  3. Blocks: These are the building blocks of your game. You can drag and drop blocks to create code that controls your game.
  4. Costumes: These are the different appearances of a sprite. You can add, delete, and modify costumes to create animations and movements for your sprites.
  5. Sounds: These are the sound effects and music in your game. You can add, delete, and modify sounds as needed.

Now that you understand the basics of the Scratch interface, you’re ready to start creating your 3D game. In the next section, we’ll show you how to create a 2D maze that you can use as the basis for your 3D game.

Building the Game World

When creating a 3D game in Scratch, designing the game environment is an important step. This involves creating the game world, which includes the backdrop and sprites that will be used in the game. In this section, we will cover the steps involved in designing the game environment.

Designing the Game Environment

The first step in designing the game environment is to create a plan for the game world. This includes deciding on the theme of the game, the layout of the game world, and the types of objects that will be included in the game. Once you have a plan, you can start designing the game world.

To design the game world, you can use the built-in tools in Scratch to create backdrops and sprites. You can also import your own images and sounds to use in the game. Use the paint editor to draw the game world and the sprite editor to create characters and objects.

Adding Backgrounds and Sprites

Once you have designed the game environment, the next step is to add backgrounds and sprites to the game. To add a background, click on the “Choose a Backdrop” button and select a backdrop from the library or create your own. You can also use the 3D backdrop editor to create a 3D background.

To add sprites, click on the “Choose a Sprite” button and select a sprite from the library or create your own. You can also import sprites from other Scratch projects or websites. Use the sprite editor to create custom sprites or modify existing ones.

When adding backgrounds and sprites, it is important to consider the size and position of the objects in the game. You can use the “Costumes” tab in the sprite editor to create multiple costumes for a sprite, which can be used to create animations and add variety to the game.

In conclusion, designing the game environment is an important step in creating a 3D game in Scratch. By following the steps outlined in this section, you can create a visually appealing game world that is engaging and fun to play.

Coding the Game

Once you have created your 2D maze, it’s time to add some code to make it 3D. In this section, we will discuss how to create movement and controls, and how to add interactions and game logic to your 3D game.

Creating Movement and Controls

To create movement and controls, you will need to use the arrow keys on your keyboard. You can use the “when key pressed” block to detect when a key is pressed and then move the player in the corresponding direction. Here’s an example code for moving the player forward when the up arrow key is pressed:

when up arrow key pressed
change y by 10

You can also add controls for turning left and right, and for jumping. Use the “if then” block to check if certain conditions are met before allowing the player to perform certain actions.

Adding Interactions and Game Logic

To add interactions and game logic, you can use the “when touching” block to detect when the player touches certain objects in the game. For example, you can create a coin sprite and use the “when touching” block to detect when the player collects the coin. Here’s an example code for adding a coin sprite:

create clone of coin
move to x: 100 y: 100

You can also add game logic by keeping track of the player’s score and lives. Use variables to store the player’s score and lives, and update them accordingly when certain events occur in the game. Here’s an example code for updating the player’s score when they collect a coin:

when touching coin
change score by 10

With these basic controls and interactions, you can create a simple 3D game in Scratch. Experiment with different sprites, backgrounds, and game mechanics to create a unique and engaging game experience for your players.

Polishing the Game

Once you have created your 3D game in Scratch, it’s time to polish it up and make it more engaging for your players. Here are some tips on how to add sound and visual effects, as well as how to test and debug your game.

Adding Sound and Visual Effects

Sound effects and music can add an extra layer of immersion to your game. To add sound effects, you can use the “play sound” block in Scratch. You can also import your own sound effects or music by clicking on the “Sounds” tab and then the “Import” button.

Visual effects can also enhance the look of your game. You can use the “change color effect” block to add different effects to your sprites. You can also use the “set backdrop effect” block to add effects to your backdrops.

Testing and Debugging the Game

Once you have added sound and visual effects, it’s important to thoroughly test and debug your game. Here are some tips on how to do that:

  • Playtest your game to make sure it is fun and engaging.
  • Use the “broadcast” block to test different parts of your game.
  • Use the “ask” block to prompt the player for input and test different scenarios.
  • Use the “debugger” feature in Scratch to help identify and fix any errors in your code.

By testing and debugging your game, you can ensure that it is a polished and enjoyable experience for your players.

In conclusion, polishing your 3D game in Scratch is an important step in creating a fun and engaging experience for your players. By adding sound and visual effects and thoroughly testing and debugging your game, you can create a game that is both immersive and enjoyable to play.

Sharing Your Game

Once you have created your 3D game on Scratch, you may want to share it with others. Here are some ways to do that:

Publishing Your Game Online

Scratch allows you to publish your game online for others to play. To do this, follow these steps:

  1. Click on the “Share” button in the top right corner of the Scratch editor.
  2. Fill out the “Project Info” section to give your game a title, description, and tags.
  3. Choose whether you want your game to be public or unlisted.
  4. Click on “Share” to publish your game.

Once your game is published, you can share the link with others. They can play your game on the Scratch website or embed it on their own website.

Sharing Your Game with Others

If you want to share your game with others directly, you can export it as an executable file. To do this, follow these steps:

  1. Click on the “File” menu in the Scratch editor.
  2. Click on “Export” and choose “Executable.”
  3. Choose a location to save the file.
  4. Share the file with others.

Keep in mind that exporting your game as an executable file only works on Windows and macOS computers. If you want to share your game with someone who doesn’t have access to those operating systems, you’ll need to publish it online instead.

When sharing your game with others, it’s important to keep in mind that Scratch projects are often large files. Make sure the person you’re sharing with has enough storage space to download and play your game. You may also want to provide instructions on how to play your game, especially if it has complex controls or objectives.

Overall, sharing your 3D game on Scratch can be a fun way to get feedback and show off your skills. Whether you choose to publish it online or share it directly with others, make sure to follow Scratch’s community guidelines and respect others’ intellectual property.
