Broadcast functions allow you to “signal” the beginning of some script you develop. Today, you will have a chance to create a custom program which will make a sprite respond to your input through broadcast and receive. This is an example of a GUI, a graphical user interface, just like the icons on your computer or apps on a smart device. See the example below for a sample of basic work. Please create multiple behaviors for your sprite which, when another sprite is clicked broadcasts a message to start a particular behavior.
