Build a GameCreating Crystal Cascade

Appendix B — Message Map

Crystal Cascade is built on messages (Custom Events): one piece of the game announces something, and the pieces that care listen. This map shows every message in the game: who sends it, who it goes to, and who hears it. A message must be spelled exactly the same where it is sent and where it is heard; this is the place to check.

Two ways to send. Trigger Custom Event goes to everyone who listens (a broadcast). Trigger Custom Event on Object goes to one Object only; the saved target chooses the sender, a newly created Object, or a selected Object. For a Shared Object Variable, the map names its binding on each sending Object.

B.1 Chains to Follow

Read each line left to right: a message, the Logic (in bold) that hears it and sends the next message, and at the end the Logic that hears the last one.
