Zone Chime

Before this: Reacting to the Game

A shop-door chime: a player who walks into an area hears a short sound. Only the player who walked in hears it, so a busy doorway stays quiet for everyone else.

How it works

You need

a brick with an Attached Zone, covering the doorway or area

zone "Zone Ref" -> chip room

Code

const SOUND = $BrickOneShotAudioDescriptor/OBA_CashRegister_Ding // the chime
const PITCH = 1.0 // 1.0 is the sound as recorded; higher is higher

@left in room: zone

on ZoneEntered(zone = room) -> (character) {
  character.PlayClientAudio(SOUND, pitch = PITCH)
}

Wire it

Compile the chip and paste it in-game. Give a brick an Attached Zone that covers the doorway.
Wire the Attached Zone’s Zone Ref to room.

Check it in game

Walk into the zone: you hear the chime once.
Stand inside: nothing more plays.
Walk out and back in: it chimes again.
Ask a friend to watch from outside while you walk in: they hear nothing.

Change it

Pick another sound: type $BrickOneShotAudioDescriptor/ in the playground, and the editor lists the sounds. OBA_UI_Checkpoint_Acquire_Tune_Cue makes a checkpoint chime.

Play a lower note on the way out:

on ZoneLeft(zone = room) -> (character) {
  character.PlayClientAudio(SOUND, pitch = 0.7)
}

Let everyone nearby hear it: change PlayClientAudio to PlayAudioAt, which plays the sound at the player’s position for all players in range.

@left in room: zone takes the zone from the Attached Zone’s Zone Ref, and on ZoneEntered(zone = room) runs each time a player walks in, naming that player character (Reacting to the Game). $BrickOneShotAudioDescriptor/... names one of the game’s sounds. PlayClientAudio plays it for that one player only, with no direction or distance: it sounds the same wherever they stand.
