WJEC Unit 2 Greenfoot question pattern

The Greenfoot practical questions are checklist-heavy. For a new scenario, expect marks for the World class, background, Actor subclass, image, objects appearing when the world opens, random movement, and the final saved name.

For an existing world, expect marks for pre-populating objects, random movement for non-player objects, arrow-key movement for the player, collision detection, removing an object, playing a sound, adding/updating a counter, and saving with the exact requested final name.

For identification questions, keep the vocabulary tight: World or Actor can be a superclass, a class is the blueprint in the class list, an object is an instance in the world, a constructor has the class name, and act() runs automatically while the scenario runs.
