We will add our first enemy to the maze. This will make it harder for the cat to move through the maze freely. The player has to choose his path wisely or risk getting caught.
We will use the Knight sprite from the Scratch library.
Click on the Choose sprite from library icon.
We search for the Knight sprite. It's in the Fantasy category.
We click on the sprite to select it, and click on OK to use it in our game.
The knight will behave quite similarly to the cat sprite. It's allowed to move through the hallways, but it can't pass through walls. That means we can reuse a lot of the scripts we've already written for the cat.
We drag both the createMaze listener script and the takeStep function from the cat to the Knight sprite to make copies there.
Then, we click on the Knight sprite to switch to its Scripts editor.
