INTERACTIVITY AND CHAPTER
GAME DESIGN C2
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.
