I want to make an object of ServerWorld inside the Item#onItemUse method. I am very new to java and modding and I need help. I tried doing ServerWorld world = new Serverworld(...); but it has a lot of parameters. So how should I do this?

You should never create a new instance of a world, the vanilla code handles that for you. In this case, you have access to the world via ItemUseContext.getWorld().

Ok thank you.
