# 1. Define the Class Structure (The Blueprint)
# This is like the Class Designer device itself.
# Note: 'int' is used here for readability; Verse uses float for health/shield values
# via the fort_character health API.
player_class := struct:
    Health : float
    Shields : float

# 2. Create Instances of the Class (The Specific Configurations)
# This is what you do in the Class Designer settings.
# These are module-scoped constants representing each class definition.
# Using functions instead of module-scoped constants to avoid the 'transacts' effect error.

# 3. The Switch Function (The Class Selector Logic)
# When a player triggers the selector, the game calls this logic.
# The 'ClassId' is the Class Identifier we set in the device.
# Note: fort_character exposes SetMaxHealth/SetHealth/SetShield via
# the /Fortnite.com/Characters API. Item grants require an item_granter_device
# wired in the editor; there is no runtime "give item by name" API in public Verse.
