Adding Engine Sounds - NeisesMike/VehicleFramework GitHub Wiki

To add engine sounds is almost the same as adding a vehicle voice.

The files must be .ogg type, but there are only two clips: whistle.ogg and hum.ogg

The hum sound plays all the time while the engine is running. The whistle sound only plays at first, and it gradually fades away.

Instead of putting your engine voice in the AutoPilotVoices folder, you'll put them in the EngineSounds folder.

And instead of using VehicleFramework.VoiceManager, you'll use VehicleFramework.EngineSoundsManager

  Okay, now go reference the Voice guide, but keep in mind the changes.

If you need an example, download VehicleFramework from Nexus and see its EngineSounds folder.
