Sound

You can also define a running sound for your machine.

The sound must be a OGG file and must be loaded in-game. Sounds are differents than models and textures and must be registered to be usable so for using custom sounds you will have either to use a mod that let you add sounds to the game or replace an existing sound with a resource pack and use it's name in the property.

The property must be defined as such : "sound": "namespace:sound_location"
