π Topic Summary
In Scratch, events are actions or occurrences that trigger a sequence of code to run. Think of them as the starting signal for different parts of your program. For example, when you click the green flag, that's an event that starts your game! Events allow different parts of your code to communicate and respond to what the user does, like pressing a key or clicking on a sprite.
Without events, your Scratch projects would just sit there and do nothing. They're what make your projects interactive and fun! This worksheet will help you understand the different types of events and how to use them in your own projects. Let's dive in! π»
