# Every time the player jumps, crouches, sprints, or gets eliminated, the
# character fires an event you can subscribe to. That's how you build reactive
# islands: a sound when they jump, a score when they sprint past a line, a
# respawn when they're eliminated. This device awards a point each time a
# player jumps — a "hops counter" minigame, no trigger volumes required.
