| 7.3. Reactive Characters

As we observe characters, so they observe us. Those who seem to have no awareness of what the player is doing often come across more like waxworks than like people. Zodiac demonstrates a scenario where the watchful presence of a dangerous criminal keeps the player from doing what he otherwise might, while Police State expands on this idea with a policeman who reacts to entire types of behavior in his presence, regardless of whether the culprit is the player or a third party. Noisemaking has a crow who will fly away in response to any loud noises the player makes.

And, of course, we definitely want to have characters react to being looked at or otherwise interfered with. Search and Seizure implements a smuggler who reacts when we try to confiscate his possessions. Pine 1 gives us a sleeping princess who can be woken by a variety of methods.

We wrap up this section with two complete puzzle scenarios that demonstrate what can be achieved by giving characters reactions to the player's behavior. A Day For Fresh Sushi has a fish who watches the player's actions and comments on them, while the live furnishings in Revenge of the Fussy Table instead comment every turn on the current state of the world, until the player has successfully sorted out all their complaints.

Because scene rules are checked every turn, they can be useful for designing puzzles which have multiple solutions. Instead of deciding the puzzle is "solved" when the player does a certain action, we set up a scene that checks to see whether the player has achieved a certain outcome -- however he accomplished it. For instance, in this scenario, we're waiting for Sleeping Beauty to wake up, and it doesn't much matter how... "Pine" A person can be asleep or awake. A person can be active or passive. The Spinning Tower is a room. "A remote corner of the old castle, reserved for spinning and weaving tasks." Sleeping Beauty is an asleep woman in the Spinning Tower. "[if asleep]Sleeping Beauty lies here, oblivious to your presence[otherwise]Sleeping Beauty stands beside you, looking a little confused[end if]." The description is "She is even more magnificent than the rumors suggested." Understand "woman" or "girl" or "princess" or "lady" as Sleeping Beauty. Discovery is a scene. Discovery begins when play begins. Discovery ends when Sleeping Beauty is awake. Marriage Proposal is a scene. Marriage Proposal begins when Discovery ends. When Discovery ends: say "Throughout the palace you can hear the other sounds of stirring and movement as the spell of centuries is broken." Instead of waking an awake person: say "Redundant." Instead of waking an asleep person: say "Yes, but how?" Instead of attacking an asleep person: now the noun is awake; say "[The noun] sits bolt upright. 'Hey! Ow!' So much for that true love's kiss nonsense." Instead of kissing an asleep person: now the noun is awake; say "[The noun] slowly stirs to wakefulness!" Instead of throwing water at an asleep person: now the second noun is awake; remove the noun from play; say "You pour out [the noun] on [the second noun]. [The second noun] wakes, shuddering. 'Agh! I had a terrible dream about drowning and then-- Hey!'" The player carries a jug of water. Understand "pour [something] on [something]" or "splash [something] at/on [something]" as throwing it at. Test me with "x beauty / wake beauty / pour water on beauty".
