Finally, the sound is played at a relatively high pitch.<\/li>\n<\/ul>\nFor this type of sound, only a single file is really necessary, but feel free to generate variations to test different settings.<\/p>\n
Implementation<\/h2>\n It is time to import your audio files in the Material<\/em> folder and start the implementation:<\/p>\n\nCreate a Polyphonic<\/em> Cue.<\/li>\nAdd a track, and drag and drop your beep sound on it.<\/li>\n<\/ul>\nNow, we need to make that repeat automatically.<\/p>\n
\nIn the Cue, click on the Waveform region<\/em>.<\/li>\nIn the Inspector<\/em>, scroll to the Timing Contro<\/em>l section and set the Auto Repeat Interval<\/em> to 350ms.<\/li>\n<\/ul>\nYou will see ghost regions appearing the timeline every 350 ms. If you play the cue, the beep will now repeat indefinitely.<\/p>\n
\n
Finally, we need to be able to adjust the timing between the beeps dynamically. Of course, we will use an AISAC for this purpose:<\/p>\n
\nFirst, create an AISAC-Control<\/em> called RadarProximity.<\/li>\nAt the Cue level, use the RadarProximity AISAC to control the Pitch<\/em> and Playback Rate<\/em>.<\/li>\nThe pitch<\/em> modulation should not be too strong. Between 0 and 0.5 raise the pitch by only 30 cents. Then speed up the increase to reach 200 cents when the AISAC value is 1. By having the pitch changing more significanty between 0.5 and 1, more emphasis is put on closer targets.<\/li>\n<\/ul>\n\n
\nThe Playback Rate<\/em> graph should start from 0.2 and end at 4. As for the pitch graph, the increase should first be moderate – when the AISAC value is between 0 and 0.5 -, and then rise quickly until the AISAC value reaches 1<\/li>\n<\/ul>\n\n
As the Playback Rate changes, the waveform regions will be triggered slower or faster. So, as the player gets closer to the danger, the radar will beep progressively faster. Try it yourself in our demo project!<\/p>\n
Popularized by the Alien franchise in entertainment, the proximity radar is now a staple of action games.
