In this section, you're going to be adding features to a simple starter file to create a game. But first, let's discuss the blocks you need to use clones. The first step in intitializing clones is to create a sprite that you want to generate clones. Give instructions to the original sprite, and within the script for the sprite, place this block to start making clones.

.

Snap! Clones are not copies of the sprite, they actually share information, so a change in the original may be seen in its clones. This block creates a clone of the selected sprite, with the same position, direction, costumes, sounds, local variables, local blocks, and scripts. Most of these properties are shared with the original, so that a change in the original changes the clone, but not the other way around. Temporary clones are deleted when the stop button is pressed.

When you want to delete specific clones, use this block:

.

To initialize clones with their own instructions, use this block:

.

Look at the starter file to see all of these blocks in action. Press space to see what this code does. This is simple code, but it has a lot of potential! We want you to change this code so that everytime the Controller sprite catches a clone, they gain a point, and each time the Controller sprite misses a clone, they lose a point. You'll see that the Controller sprite has no code. Change that by adding this script:

.

Now when you move your mouse, the Controller sprite follows, but it still does nothing when it touches the clones. Using a "delete this clone" block, add a script to Clone sprite so that when it touches the Controller sprite, it gets deleted. The game should now look like this:

.

Lastly, to make it a true game, add a "score" variable so that when the Controller catches a Clone, it earns a point, and when it misses a clone, it loses a point. Alternatively, you can make the Controller gain a point when it evades a clones, and lose a point when it gets hit by a clone. It's up to you, the possibilities are endless!

You made a game using clones! Clones are extremely useful in simplifying your code if you want to make a game, like with your final project. Good luck!
