Have you ever wanted to make a game or a fun program where things happen when you click or touch them? That’s what you can do with Sprite Lab! In Sprite Lab, you can make your program respond when someone interacts with it. Let’s learn how to do that using something called event blocks.
Event blocks are special pieces of code that tell your program to do something when an action happens. For example, there are blocks like when clicked or while touches. These blocks wait for you to click or touch something, and then they make your sprites do cool things!
Imagine you have a sprite, like an alien, and you want it to change size when you click on it. You can use the when Alien 1 clicked event block and attach a change size by block to it. Now, whenever you click on the alien, it will grow or shrink!
Event blocks are like little programs of their own. They don’t connect to your main program but work separately. This means you can have lots of different things happening at the same time!
Sometimes, you might want to stop an event from happening over and over again. For that, you can use a stop block. This block helps you control when you want things to stop, so your program doesn’t get too crazy!
With event blocks, you can create amazing and interactive worlds. You can make games where characters jump, dance, or even change colors when you click them. The possibilities are endless, so give it a try and see what fun programs you can create!
Interactive Story Time: Create a simple story using paper cut-outs or drawings of characters. Assign each character a specific action when touched, like making a sound or moving to a new spot. Use your imagination to tell a story where each character’s action helps move the story forward. Discuss with your friends or family how event blocks in Sprite Lab are similar to the actions you assigned to your characters.
Event Block Hunt: Go on a scavenger hunt around your home or classroom to find everyday objects that could have “event blocks.” For example, a light switch can be an event block that turns the light on or off when clicked. Make a list of these objects and describe what action happens when you interact with them. Share your findings with your classmates and see how many event blocks you can find!
Design Your Own Game: Use paper and crayons to design a simple game. Draw a scene and create characters (sprites) that can do different things when you touch them. Think about what actions you want each character to perform. For example, a cat sprite could meow when clicked. Explain how you would use event blocks to make your game come to life in Sprite Lab.

Now that you’ve learned how to use Sprite Lab, you’re going to want to make your program react when someone interacts with it. To do that, you’ll use event blocks. Blocks like `when clicked` and `while touches` are examples of event blocks. The code connected to an event block runs when the appropriate input, such as a click or a tap, is detected.
For example, if you attach the `change size by` block to the `when Alien 1 clicked` event, the sprite will change size when it’s clicked. Notice that event blocks don’t snap into your main program; instead, they create separate little programs of their own. Remember that even if the event only happens once, the behaviors will continue until you stop them. You can use a `stop` block if you don’t want multiple events to combine behaviors.
Using events, you can create imaginative programs and interactive worlds. Give it a try!
