INTERACTIVITY AND                                                                      CHAPTER

                      Learning Outcomes


                     The students will be able to:
                         use Broadcast and Receive blocks to enable sprite communication.
                         implement Events and Operators for interactivity.
                         use Sensing blocks to detect user input and trigger actions.
                         coordinate multiple scripts for smooth game execution.



                  In this chapter, you will learn how to make your Scratch projects more interactive using
                  Broadcast and Receive blocks, Events and Operators, and Sensing blocks. These tools
                  help us create fun and engaging games by allowing sprites to communicate, respond to

                  actions, and interact with users.



                            BROADCAST AND RECEIVE BLOCKS

                  Broadcast and Receive blocks are present in Events block category. These blocks allow
                  sprites to communicate with each other without being directly connected. This is useful for

                  controlling different parts of a story or game.



                              Blocks                                       Functions



                                             It sends messages to multiple sprites and activates all scripts linked
                                             to the message, enabling synchronized actions. This helps coordinate
                                             events like background changes, animations, and game controls.
                                             It sends a message to all scripts and waits for their completion. This
                                             ensures tasks run in sequence rather than simultaneously. It is useful
                                             for step-by-step animations and game events.

                                             It waits for a specific broadcasted message before executing its script,
                                             ensuring synchronised actions in games and animations. It also helps
                                             coordinate multiple scripts, ensuring they run only when needed.
