# Section:    Using Abstraction for Creating a Zone Class
# A zone is an area of the map (represented by a device) that can be Activated/Deactivated and that provides events to signal when the zone has been "Completed" (can't be completed anymore until next activation).
# Zone "Completed" depends on the device type (ActivatorDevice) for the zone.
# Suggested usage: ActivateZone() -> ZoneCompletedEvent.Await() -> DeactivateZone() #
base_zone<public> := class:
ActivatorDevice<public> : creative_object_interface
ZoneCompletedEvent<public> : event(base_zone) = event(base_zone){}
GetTransform<public>() : transform =
ActivatorDevice.GetTransform()
# Activates the Zone.
# You should enable devices and any visual indicators for the zone here.
ActivateZone<public>() : void =
# The base zone can handle zones defined as item spawners or capture areas.
# Try and cast to each type to see which we're dealing with.

CaptureArea.Enable()
spawn { WaitForZoneCompleted(option{CaptureArea.AgentEntersEvent}) }
else if (ItemSpawner := item_spawner_device[ActivatorDevice]):
ItemSpawner.Enable()
spawn { WaitForZoneCompleted(option{ItemSpawner.ItemPickedUpEvent}) }
# Deactivates the Zone.
# You should disable devices and any visual indicators for the zone here.
