LEARNING TO USE MESSAGES AND BROADCASTING Messages are how scripts can communicate with each other. Messages can be used to control: - Costume changes, - Backdrops, - When scripts stop and start and much more. They are some of the most useful tools in your toolbox. This project shows one of the most basic ways you can use messages. Please remix it and add some more messages to change the backdrops and costumes. (HINT: Check the backdrop for scripts, too!)
