I have a question: I create the map came across such a thing like sounds. How to use it? And if I add sound to the map and run it so my friends and I can play, can they hear it?
@odinsamejima as @Uncle already said, it's a DDNet only feature. You and your friends will need to use the ddnet client to use map-sounds. That's not a vanilla feature and I guess nobody here will support you with that. Please ask for help at the ddnet discord.
