My game allows custom level creation with a menu to access the locally-saved user-created levels. These levels are saved using Native.FileUtils. Is there some way to get how many files are in any folder foo?
You can simply use fileUtils.listFiles(folder).length to get number of files in a folder. But the answer maybe not you want, you will get a string[] of file names when use listFIles(), write your own rule to count fileNum.
let folder = "xxx";
let files = f.listFiles(folder);
let fileNum = files.length;
