how do i set up the attached server? also, iron golems and pumpkins would be cool if they arent already in the game
You need node.js downloaded. You can just search it up and run the installer and then it should work. To debug this kind of issue in the future, right click the folder and hit "open in terminal" and then type "./server.bat", this will execute the server inside your already opened terminal, allowing you to see any errors after it stops. :)
