Minecraft OneBlock plugin Used AI

A neat trick: letting map builders create the map on one server, then when it's ready, zip it up and unpack it into a fresh new folder every time the server is launched. This way, we have consistent restore just in case someone manages to break the map, and builders do not have to worry either because they work on the map on a completely separate server

Storing partially completed quests is so tricky

Implemented per-island challenges. Hope no bugs will come out of this

Implemented tracking block collections
Also learned that WorldGuard is not ideal for managing co-op mates permissions :(
The image shows how the island is saved inside MongoDB for now. It's important to keep it under 16 MiB, the BSON document limit

Implemented the generating block and a protection system using WorldGuard regions. In the video the other player is a visitor and not a member of this island and he cannot pick items up from the ground. Today was easy and I'm satisfied with the progress so far :)

Finally done messing with concurrency and CompletableFutures to implement a safe island saving and loading system. It survived massive spam calling (stress testing). Thanks to FastAsyncWorldEdit for supporting asynchronous world operations like it's nothing!
