Event-driven programming is an important idea in Scratch that helps you make fun and interactive projects. Events are actions that start scripts, which make your characters (called sprites) react to different situations. Here’s how you can create event handlers in Scratch:

1. Choose Your Events

Scratch has many built-in events you can use. Here are some common ones:

• When Green Flag Clicked: This starts your project.
• When [key] Pressed: This responds when you press a certain key. For example, if you want your sprite to jump when you press the spacebar, you would use this event.

2. Add an Event Block

To make an event handler:

• Open your Scratch project.
• Drag the right event block from the "Events" section on the left side into your scripting area.

3. Attach Action Blocks

Now that you have your event, you'll want to make it do something!

• Drag action blocks from groups like "Motion," "Looks," or "Sound" and attach them under the event block. For example, after the "When Space Key Pressed" block, you can add a "change y by 10" block to make your sprite jump.

4. Test Your Project

After you’ve set up your event handlers and actions, click the green flag or press the key you chose to see how your sprite reacts. Feel free to try different events and actions!

By learning how events trigger actions in Scratch, you can create exciting stories, games, and animations!
