Course Description

Scratch is the best educational programming software for kids available today. With Scratch, you can create games and interactive art projects all while having lots of fun!

Designed by the MIT Media Lab’s Lifelong Kindergarten Group for 8 to 16 year olds, Scratch is a free programming environment that runs in your web browser. But Scratch users consist of people of all ages, including younger children with their parents. The software makes it easy for anyone to start developing their programming and problem-solving skills.

I’m Al Sweigart, the author of several programming books for kids and beginners. This course follows the content of my latest book Scratch Programming Playground, which you can read for free online under a Creative Commons license. This is my second Udemy course following my highly-rated "Automate the Boring Stuff with Python Programming".

This course (and supplemental book) covers the creation of several classic games like brick Breaker, Snake, and Fruit Ninja. Instead of memorizing a list of programming concepts, you’re guided through making these games and picking up programming concepts on the way. The lectures follow the 6 game and computer art projects, along with additional content on debugging and experimenting with Scratch.

This course won’t make you a software engineer or app developer, but it can provide kids with fun activities and give parents and K-12 teachers the training they need to help children learn to code. By the end of this course, you’ll have a solid understanding of Scratch and its community of millions of users.

What are the requirements?

  • How to use a mouse (right-clicking, dragging).
  • Typing proficiency is helpful but not required.
  • No previous programming experience is needed.

What am I going to get from this course?

  • Program 6 different video games and interactive art projects.
  • Figure out how to experiment with Scratch to continue learning.
  • Share and show off their projects to others in the Scratch community.
  • Help others discover and learn programming techniques in Scratch.

Who is the target audience?

  • Kids ages 8 to 16 who want to make fun programming projects.
  • Parents who want to help their kids learn to program.
  • Teachers, including non-technical instructors, who want to guide afterschool coding clubs.
  • This is not an introduction to becoming a app developer or professional software engineer.

You'll also see how clones can delete themselves when they are no longer needed.

Lecture 19 Quiz
4 questions
10:13

In this lecture, you use sprites to display text messages on the Stage. By the end of the lecture, you'll have a better understanding of how everything on the Stage is either a sprite or a clone of a sprite.

In this lecture, you will once again deploy a simple math equation to control the trajectory of the fruit. You'll also reuse the gravity techniques introduced in the basketball game, as well as the "clone generator" technique used in the brick breaker game.

Lecture 30 Quiz
2 questions
14:18

In this lecture, you'll implement the code for the slice sprite to detect when it is cutting the fruit. This involves using the "broadcast" block to communicate between two sprites. You'll also use broadcasts to control various game events: when the game starts, when a fruit is missed, and when the game ends.

Lecture 31 Quiz
3 questions
15:27

In this lecture, you finish the Fruit Slicer game. You'll learn how to use a white sprite to implement a "fade to white" animation effect. You will also extend this game with a cheat code and a website-wide high score system. By the end of this lecture, you'll have used Scratch's advanced "cloud variables" to keep track of the highest score of everyone who's played the game on the Scratch website, as well as how cloud variables work and their limitations.
