Making A Character

Today, we're going to create a little interactive maze. You won't complete the maze directly, instead, you'll guide a little character through the maze. To start with, let's create the character.

Making the Maze

Now that we have the character, the next bit is to create the maze for them to navigate through.

For this part, you'll learn how to let different sprites interact with each other. Sprites can communicate via the “broadcast”-block. It broadcasts a message to all sprites and every sprite that has one or more “When I receive (message)” hat blocks with the corresponding message, reacts accordingly.

You can create a new message by clicking on the input slot of the “broadcast” or “When I receive” block and select “new...” or pick one of the existing messages of your project from the same dropdown menu.

A little twist

While moving through the previous video, you also learned how to check for “physical” sprite interaction with the “touching”-predicate. You can select another sprite of your project from the block’s dropdown menu. This type of value is called a Boolean value. Booleans are important terms in computer science. The block then reports “true”, whenever the currently selected sprite is touching the sprite indicated in the input slot and “false” otherwise.

What else can we do?
