Kun enum-vakioon viitataan, käytetään syntaksia enumName.constName, jossa enumName on enumeraattorin nimi.
Enumissa tulee olla viisi alkiota. Tarkista switch-lauseen tapaukset selvittääksesi, mitä vakioita käytetään. Yksi niistä on Invisibility.

Suggested prompts:

What is the code for the switch statement so I can see all the enum members?

Can you show me the part of the code where the enum is defined?

Can you list all the constants used in the switch statement?

Awesome!
