When you start using Scratch, you’ll see that event-driven programming is all about how certain things can make other things happen. It’s really fun and a key idea in computer science. So, let’s check out the different types of events you can use in Scratch!
This is usually the first event that newbies try. When you click the green flag at the top of the screen, it starts all the scripts linked to this event. It’s like saying, "Let’s get started!" For example, when you click the green flag, you can make a character say "Hello!" or start a cool animation.
You can make your sprites react to keys on the keyboard using the "When [key] key pressed" event. For example, if you press the up arrow, a character might jump or move forward. This makes your project interactive and fun!
This event makes something happen when you click on a specific sprite. Imagine having a button in your project; you can program it to change color or play a sound when you click it.
Broadcasting is a handy tool in Scratch. You can send messages between sprites. For example, one sprite can send a message like "Start Game," and another sprite can start dancing as soon as it gets that message.
If your project has different backdrops, you can make things happen when the backdrop changes. For example, if you change the backdrop to "Day," your sprites could change their outfits or colors.
Scratch lets you react to time too. Using "When [timer] > [number]," your sprites can do things after a certain time. For example, after 5 seconds, a sprite could say "Time's up!"
By learning about these events in Scratch, you’re not just writing code; you’re creating fun stories and games that react to what users do! Enjoy coding!
