How to make a 3d platformer in Scratch?

Getting Started with 3D Platformer in Scratch

Scratch is a popular block-based programming language developed by MIT, designed for children and beginners. It allows users to create complex animations and interactive stories by dragging and dropping objects. In this article, we’ll show you how to create a 3D platformer in Scratch.

Setting Up Scratch

To start making a 3D platformer in Scratch, you need to have the latest version of the software installed. Follow these steps to set up Scratch:

• Download and install the latest version of Scratch from the official website: https://scratch.mit.edu/
• Open the Scratch environment and create a new game by clicking on the "File" menu and selecting "New Game"
• Choose the game type as "3D" and click on the "OK" button

Creating the 3D Environment

To create a 3D environment, you’ll need to import a 3D file or create one from scratch. You can download a 3D model from websites like itch.io or Unity, or create your own using any 3D modeling software.

Here’s a step-by-step guide to creating a 3D environment in Scratch:

• Import a 3D file: In the "Model" panel, select "Import 3D file" and choose the 3D file you downloaded or created.
• Load the 3D model: Load the 3D model into the "Model" panel by clicking on the "File" menu and selecting "Open"

Creating the Platformer

Now that you have a 3D environment, you can start creating the platformer. Here’s a step-by-step guide:

• Create a new object: In the "Objects" panel, create a new object by clicking on the "New Object" button
• Add a circle for the player: Create a new circle object by dragging and dropping it from the "Objects" panel
• Add a ground: Create a new rectangle object by dragging and dropping it from the "Objects" panel
• Add platforms: Create new objects for each platform by dragging and dropping them from the "Objects" panel
• Position the platforms: Position the platforms at different x-coordinates to create a 3D environment

Creating the Player Character

To create the player character, you’ll need to add a rectangle object. Here’s how:

• Create a new rectangle object: Drag and drop a rectangle object from the "Objects" panel
• Add animations: Add animations to the rectangle object by dragging and dropping them from the "Animation" panel
• Add a sprite sheet: Create a new sprite sheet by dragging and dropping it from the "Sprites" panel
• Position the player: Position the player at the center of the screen by adjusting the x and y coordinates of the rectangle object

Adding Collision Detection

To create collision detection, you’ll need to add a collision rectangle to the player object. Here’s how:

• Create a new rectangle object: Drag and drop a rectangle object from the "Objects" panel
• Add a sprite sheet: Create a new sprite sheet by dragging and dropping it from the "Sprites" panel
• Position the collision rectangle: Position the collision rectangle at the center of the player object by adjusting the x and y coordinates of the rectangle object

Adding Movement and Controls

To add movement and controls, you’ll need to create movement objects and add event listeners to them. Here’s how:

• Create movement objects: Create new objects for each direction (up, down, left, right) by dragging and dropping them from the "Objects" panel
• Add event listeners: Add event listeners to each movement object by dragging and dropping them from the "Event Listeners" panel
• Control the player: Control the player’s movement using the event listeners

Drawing the Platformer

To draw the platformer, you’ll need to create an array of objects to represent the platforms and add drawing commands to them. Here’s how:

• Create an array of objects: Create a new array of objects by dragging and dropping it from the "Objects" panel
• Add drawing commands: Add drawing commands to each object by dragging and dropping them from the "Drawing" panel
• Render the scene: Render the scene by dragging and dropping the "Draw Screen" object from the "Objects" panel

Putting it all Together

Here’s a sample code snippet to get you started:

// Import the 3D model

import_model 3d_model



// Create the player object

create_object player

add_circle player



// Add a ground object

add_object ground

add_rectangle ground

position_ground(0, 50, 100)



// Create platforms

add_object platform1

add_object platform2

add_object platform3

position_platform1(50, 0, 0)

position_platform2(0, 200, 0)

position_platform3(0, 0, 200)



// Add collision detection

add_object collision_rect

add_sprite_sheet collision_rect

position_collision_rect(0, 0, 100, 100)



// Add movement and controls

add_object movement_rect

add_sprite_sheet movement_rect

position_movement_rect(50, 0, 100)

add_event_listener movement_rect



// Draw the platformer

add_object draw_screen

add_pigment draw_screen

position_draw_screen(0, 0, 0, 0, 200)

This code snippet creates a simple 3D platformer with a player, ground, and platforms. You can add your own game logic and features to create a more complex platformer.

Tips and Tricks

• Use Scratch’s built-in tools to create complex animations and interactions.
• Experiment with different 3D models and textures to create unique environments.
• Use Scratch’s built-in physics engine to create realistic collisions and movements.
• Consider using other programming languages or engines to create a more complex game.

Conclusion

Creating a 3D platformer in Scratch is a fun and rewarding experience that allows you to explore new techniques and tools. With this article, you now have a solid foundation to build upon and create your own 3D platformer. Remember to experiment with different techniques and tools to create a unique and engaging game. Happy programming!
