Ultimate Game Design : Building game worlds

Audio
This simple script replaces material information for the rising ice crystals:
// JavaScript sample of "material" trigger support
if(iceCrystal.rising()) {
iceCrystal.setTexture(animatedLightTexture);
}
Audio triggers cover all audio events. If an audio trigger is tripped, it might cause
the audio to change from ambient to “fight scene” music. It might simply start a new
ambient audio event (like water-dripping echoes in a cave). It might cause some
voice-over narration. It might cause a specialized “one off” sound, like a customized
explosion with the last words of a dying character mumbled at a distance.
This script sample sets the background music to a fighting soundtrack when a
fight breaks out:
Message
Light
C H A P T E R 6
// JavaScript sample of "audio" trigger support
if(player.startedFighting()) {
audioSystem.setBackgroundMusic(fightingTrack);
}
A message trigger can be used to print a message directly to the player, deliver a message
to the player’s interface system, or prompt an NPC event. Message triggers can also
be used to print up messages for testing purposes to notify the player/tester about the
state of something in the map.
Here’s a sample message script for printing a bonus level message:
// JavaScript sample of "message" trigger support
if(player.hasEntered(bonusArea1)) {
messageSystem.prompt(bonusLevelMessage);
}
Light triggers are used to create custom-lighting situations. Maybe we want to try to
show visually an “end of time” scenario, as if day after day of sunlight is passing in
the outside garden from our perspective inside a vast palace. We can do this with a
light trigger that launches a repeating light-track animation simulating the position
change of the sun in the sky.
