Sonic game on Scratch

Creating games on Scratch is both fun and educational as they help any new beginner to understand the basics of coding and game development while creating amazing and innovative games. Users have created many popular games on Scratch like Pac-man, 3D games, Geometry Dash, and many more!

With this game tutorial, we will guide you in creating yet another interesting and popular game called Sonic game on Scratch!

How to make a Sonic game on Scratch 3.0?

Sonic game is one of the most popular games among kids in which the main character has to move or jump to avoid all the obstacles coming his way and move onto the platforms for moving forward in the game. It comes in the category of platform games.

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

  • Step 1: Open Scratch and start creating sprites. For this game, you will be using the pre-made Scratch cat sprite as the sonic character, so rename it as ‘Sonic’ to avoid confusion while coding. You can also use any other sprite as the ‘Sonic character’.
rename the sprite as ‘Sonic’
  • Step 2: You need to have at least 5 different costumes of any type for the ‘Sonic’ sprite, as shown below. Make sure to rename the sprite’s costumes as ‘Sonic1’, ‘Sonic2’, ‘Sonic3’, ‘Sonic4’, and ‘Sonic5’ for each costume accordingly to avoid confusion while coding.
5 different costumes
  • Step 3: Now, to draw another sprite, click on the blue circle with the cat icon.

  • Step 4: After clicking on the blue circle for choosing a sprite, select the second option from below that says ‘Paint’.
select the second option
  • Step 5: Once you click on the ‘Paint’ option, the following screen will appear.
click on the ‘Paint’ option
  • Step 6: Using the rectangle option and the fill option, draw this sprite as shown below.

  • Step 7: Rename this sprite as ‘Platform’ to avoid confusion while coding.
Rename this sprite as ‘Platform’
  • Step 8: Select the ‘Sonic’ sprite and change its size to ‘40’ and place it in the stage as shown below.
Select the ‘Sonic’ sprite
  • Step 9: After drawing 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 variables named ‘X’, ‘Y’, “XSpawn’, ‘YSpawn’, and ‘Level’. Make sure to select the ‘For this sprite only’ option while creating the sprites.

How to Make a Pong Game on Scratch: A Step-by-Step Tutorial [+Free game code download]

A Pong game is where you use a paddle to try and stop a continuously moving object such as a ball from hitting the bottom of the screen. Every time the paddle hits the ball it rebounds from it and you will get a score. In Scratch, you will use sprites to set up the ball and paddle and write code to achieve the game objectives and set up the scoring system.
