# SPAWNER WAVES — a survival horde driven by the NPC Spawner device.
#
# The npc_spawner_device is the front door to putting characters in your world
# from Verse. You pick WHO it spawns in the editor (its NPC Character Definition);
# Verse decides WHEN and HOW MANY. Here a button starts a wave, the device fires
# SpawnedEvent for every character it creates, EliminatedEvent every time one
# falls, and when the whole wave is down we roll the next one — bigger each time.

    # Drop your NPC Spawner here. Choose its character (zombie, husk, custom) in
    # the editor — Verse just commands the spawns.
