Introduction & Learning Objectives
Learning Objectives
Define a 'game environment' and identify its key parts, like objects and backgrounds.
Place objects (sprites) in specific locations within a game environment.
Use an 'event' block (like 'when green flag clicked') to start an action.
Use a conditional 'if/then' block to make an object interactive.
Explain how rules make a game environment fun and challenging.
Create a simple interaction, such as collecting an item or avoiding an obstacle.

Core Syntax & Patterns
The 'When' Block (Event Trigger)
WHEN [ a specific event happens ]
Use this block to start any script. It tells the computer to listen for an event, like a click or a key press, and then run the code attached below it.
The 'If/Then' Block (Conditional Logic)
IF < condition is true > THEN { do these actions }
This block is like a guard. It checks if a condition is true (like 'touching a coin?'). If it is, it lets the code inside the 'Then' part run. If not, it skips it.
The 'Go To' Block (Positioning)
GO TO X: [number] Y: [number]
Use this to place an object at an exact spot in your game world. X is for left and right, and Y is for up and down.
