In this article, we are going to show you how to make a 3-dimensional game or project in the Scratch programming language. This type of project can be used for various purposes, such as learning about 3D shapes and their properties or creating a game with an interesting 3D environment.

## How to make a 3D game in Scratch?

For creating a 3-dimensional game in Scratch, the most important thing you need to know is the knowledge of the illusion of depth because the Scratch platform is for creating 2-dimensional games as it offers an x-axis which gives the perspective of left and right coordinates and a y-axis which gives the perspective of up and down coordinates. For a 3-dimensional platform, a third axis, that is, the z-axis is also required which runs at a right angle to the x-axis and y-axis.

To create the illusion of depth, Scratch mostly uses changes in movement and size. In this article, I will explain how to make a 3D maze game in Scratch using a 2D element. This will be done by the method of ‘raycasting’.

So, to create a 3D maze game in Scratch, just patiently follow the below-given steps:

• Step 1: Open Scratch and start creating sprites. Before drawing new sprites, make sure to delete the cat sprite. For this game, you need to create 4 different sprites. Now, to create the first sprite, click on the blue circle with the cat icon.
• Step 2: After clicking on the blue circle for choosing a sprite, select the second option from below that says ‘Paint’.
• Step 3: Once you click on the ‘Paint’ option, the following screen will appear.
• Step 4: Now, first draw a 2D maze using the line option with two openings on opposite sides which will act as the ‘exits’.
• Step 5: Rename this sprite as a ‘maze’ to avoid confusion while coding.
• Step 6: To create the second sprite, just repeat steps 1, 2, and 3 and after repeating these steps, simply draw the exit lines as you did in the first sprite.
• Step 7: Rename this sprite as ‘exit’ to avoid confusion while coding.
• Step 8: To create the third sprite, again repeat steps 1, 2, and 3 and after repeating these steps, create a with “YOU WIN!!!” text on it using the text option.
• Step 9: Rename this sprite as ‘win’ to avoid confusion while coding.
• Step 10: For the fourth sprite, you need to draw the main player. So, for that, again repeat steps 1, 2, and 3 and after repeating these steps, simply draw a box using the rectangle option and rename this sprite as ‘player’.
• Step 11: After drawing all the sprites, it’s time to make the variables of the game. So, first, switch to the ‘Code’ section, then go to the “Variables” block in the block palette, click on the ‘Make a Variable’ option, and create a variable named ‘distance’, ‘Angle’, ‘Speed’, and ‘Counter’.
• Step 12: After making the variables of the game, it’s time to make a list of the game. To make a list, go to the “Variables” block in the block palette, click on the ‘Make a List’ option, and create a variable named ‘Dists’.

## Code to trigger the ‘YOU WIN!!!’ text

It’s time for coding, so let’s start by creating a code to trigger the ‘YOU WIN!!!’ text when the player passes the opening points, that is, exits of the maze. Make sure that the ‘WIN’ sprite is selected while coding this part.

• Step 1: Go to the “Events” block in the block palette, select the ‘when green flag clicked’ block, and drag it to the coding area.
• Step 2: Go to the “Motion” block in the block palette, select the ‘go to x: ( ) y: ( )’ block, drag it to the coding area, and place it under the ‘when green flag clicked’ block.
• Step 3: Go to the “Control” block in the block palette, select the ‘forever’ block, drag it to the coding area, and place it under the ‘go to x: ( ) y: ( )’ block.
• Step 4: From the “Control” block in the block palette, select the ‘if ( ) then ( )’ block, drag it to the coding area, and place it inside the ‘forever’ block.
• Step 5: Go to the “Sensing” block in the block palette, select the ‘touching ( )?’ block, drag it to the coding area, and place it in the if condition of the ‘if ( ) then ( )’ block inside the ‘forever’ block.
• Step 6: In the ‘touching ( )?’ block, select the value as ‘player’ from the drop-down menu.
• Step 7: Go to the “Events” block in the block palette, select the ‘broadcast ( )’ block, drag it to the coding area, and place it in the then condition of the ‘if ( ) then ( )’ block inside the ‘forever’ block.
• Step 8: In the ‘broadcast ( )’ block, select ‘New Message’ from the drop-down menu and name the new message as ‘Win’.
• Step 9: Go to the “Control” block in the block palette, select the ‘stop (all)’ block, drag it to the coding area, and place it under the ‘broadcast ( )’ block in the then condition of the ‘if ( ) then ( )’ block inside the ‘forever’ block.
• Step 10: In the ‘stop (all)’ block, select the value ‘this script’ from the drop-down menu.

## Code to display the ‘YOU WIN!!!’ text

Make sure that the ‘WIN’ sprite is selected while coding this part.

• Step 2: Go to the “Motion” block in the block palette, select the ‘point in direction ( )’ block, drag it to the coding area, and place it under the ‘when green flag clicked’ block. In the ‘point in direction ( )’ block, leave the value as ‘90’.
• Step 3: From the “Motion” block in the block palette, select the ‘go to x: ( ) y: ( )’ block, drag it to the coding area, and place it under the ‘point in direction ( )’ block.
• Step 4: Go to the “Looks” block in the block palette, select the ‘hide’ block, drag it to the coding area, and place it under the ‘go to x: ( ) y: ( )’ block.
• Step 5: Again go to the “Events” block in the block palette, select the ‘when I receive ( )’ block, and drag it to the coding area.
• Step 6: In the ‘when I receive ( )’ block, select the value as ‘Win’ from the drop-down menu.
• Step 7: Go to the “Looks” block in the block palette, select the ‘show’ block, drag it to the coding area, and place it under the ‘when I receive ( )’ block.

## Conclusion

Creating a game in Scratch may seem initimidating and hard, especially to a beginner who is not fully aware of all the features and functions of all the elements of the Scratch editor. But by remaining consistent with your learning process and with practice you can create many interesting games. If you want more 3D game ideas then go to the project page of Scratch to get some inspiration and start giving shape to your imagination.

What is raycasting?
Raycasting is a method used to efficiently make a 3D game from a 2D game.

What is the difference between 2-dimensional and 3-dimensional surfaces?
The difference between 2-dimensional and 3-dimensional surfaces is that 2-dimensional surfaces have only two axes, that is, the x-axis and y-axis, whereas, 3-dimensional surfaces have one more axis along with the x-axis and y-axis, that is, the z-axis which provides the illusion of depth and runs at a right angle to the x-axis and y-axis

What does radar do in Scratch?
In Scratch, the radar track of the space available between the player and the walls helps in allowing the game visuals to adjust as per the movement of the player.

What perspective do the x-axis and y-axis provide?
The x-axis provides the perspective of left and right coordinates and the y-axis provides the perspective of up and down coordinates.

How to add an extension in Scratch?
To add an extension in Scratch, click on the option available on the bottom-left side of the screen that says ‘Add Extension’.
