the assets folder of versions above p>1.7.1 has been modified, and now there are only two folders. One is indexes, and the other is objects. Game audio and the music code are in indexes. When you open it with WordPad, there will be a bunch of numbers and letters. Don't modify them at will! If you accidentally modify it, don't press Save! If you are genuine, it will automatically download and overwrite your original modification. Otherwise, you have to disconnect the network to modify it successfully.
game audio is put in p>objects and the suffix is removed. Names are codes for sound effects. There are many folders, and folders are the first two letters or numbers of the sound effect code.
like this, it is a kind of subtitle that appears after opening json file in indexes with wordpad. All subtitles have the same format.
"sounds/music/menu/menu1.ogg": {
"hash": "c157c56846fe562f88fecd9d69423dd6c41",
"size": 1744657
},
c157c56846fe562f88fecd9d69423dd6c41 is the code of sound effect. In the version above 1.7.1, you can copy and paste this code into an ogg audio format and then replace the sound effect in the specified folder (for example, replace the record music, which is available online).
