How to make scrolling backgrounds in Scratch

Breaking out of Scratch's 480-pixel screen is on the wishlist of most new coders, but the math can seem a little tricky until it's explained properly. In this short tutorial, Mr. T walks you through the process of sliding background tiles around to create the illusion of an infinite background.

01:08 Let's start coding
02:02 Your backgrounds is stuck on the screen
03:46 How does the Mod block work?

Check out Mr. T's Scroll-O-Matic, a custom block that handles ALL the math for you so you can create custom blocks no sweat. https://scratch.mit.edu/projects/8260...

Created by Atomec Studios and narrated by veteran tech educator Andrew Tomec, SCRATCH HACKS is a new series of quick and simple Scratch coding tutorials aimed at beginner- to intermediate-level coders. Scratch Hacks aim to take the fear factor out of coding with byte-sized video tutorials that offer tips and advice on the most common questions and problems that arise when youngsters first take up coding in Scratch. In his work as a Canadian elementary school teacher, Mr. T has taught hundreds of introductory coding classes to children from kindergarten up. "I was struck by how often the same simple questions arise in every class I teach. Learning to code is like learning any other language, and these compact lessons will help give learners the vocabulary they need to express themselves in the digital world."
