Core Syntax & Patterns
The Event-Action Rule (If-Then)
WHEN an event happens, THEN an action starts.
This is a computer science conditional! Use this rule to make your story interactive. The 'event' is the cause (like a click) and the 'action' is the effect (like a sound playing).
The Media Layering Rule
1st: Background Image, 2nd: Characters/Objects, 3rd: Text/Buttons
Think of it like making a sandwich! You put the layers in order. The background is always at the very back, characters go on top of that, and words or buttons go on the very top so you can see them.
The Story Sequence Rule
Beginning -> Middle -> End
Every good story follows this simple plan. The beginning introduces your characters, the middle is where the main action happens, and the end finishes t...
