I usually make custom horns by just using the file path to the sound file, but I've found that horns created in this way don't have a very large range. The sound fades out completely only a few metres away from the source, unlike the vanilla horns. Right now, I've figured out how to increase the volume of horns, using "obj:setVolume" in some lua code, but that's it. Is there some command I can use or otherwise to increase the range of custom horns like this?
