Posted January 26, 20169 yr Hello everyone. I think I'm asking for some tips and advice for somewhat non-trivial stuff regarding minecraft mods. So I made a Trade mod with IndustrialCraft support. You interact with other players through a GUI in which you can trade items and IC-Energy. All that stuff works quite fine. Also per dedicated Server. I'm rewriting a lot of stuff now to expand the mod. My plan is that players can create offers/demands, that will be visible in a list. So I create a DataManager Singleton that gives me access to the data. This data obviously disappears when the server is restarted. I know with tile entities you can solve that with the whole NBT Compound thing. But my structure isn't a Tile Entity. Are there other "Entity" things that are globally accessible, where I can simply use NBTs to save things and send to the Clients? If not, I could try to connect it with the Trade Block Tile Entity, but I only need one Manager, so maybe the first Trade Block is my manager. But what if the first block is destroyed? should I just copy the Manager to a different entity? What if all trade blocks are destroyed? This connection doesn't seem very smart to me. I could also try to do it in Vanilla Java and convert everything to primitives in a serializable class. Like that I can write the data in a file that is saved in the world folder I think its also not a big problem to handle the communication to the clients who are asking for the data. But here I don't know when exactly to save and load the file. In my understanding the obvious answer is "load when the world is started", "save when the world is closed", but how do I do that from a vanilla class? Right now I think I only have the init()-Events, which doesn't have a world yet. So I'm not sure if this is the best solution either. Maybe I'm just missing a keyword that I could google. I'm thankful for any post, even if it's "You are doing it wrong!", if you can explain me what. I'm here to learn. So thanks, and have a nice day everyone. TL;DR: What is the best way to make a global Data Structure in Minecraft Forge with a unique Data Manager that persists after a World/Minecraft restart? edit: Oh and I forgot to mention, that I'm using Minecraft 1.7.10. - added it to the title.

Saving and loading WSD happens on demand. If you would need additional hooks look at forge events (World events probably). 1.7.10 is no longer supported by forge, you are on your own.

Maybe I will need some help later on, but at the moment I think I know what to do. see ya
