Hello, I am here to present my homemade Minecraft server implementation (different from the Notchian one made by Mojang). https://github.com/Minestom/Minestom Discord server: https://discord.gg/RAySDQA You can take a look at the readme to have a glimpse over what I want to achieve but firstly, I'll say that my goal isn't to replace spigot at all. We have different goals in mind which are why I thought that making this implementation could be good for some people. The goal here is to offer a way to make a server without the vanilla features that take most of your CPU power for nothing (I'm thinking about the world system, AI, pre-calculated things for nothing), and obviously, the whole server here is multi-threaded! !NEW! Vanilla features are gonna be implemented as an optional addon over here: https://github.com/Minestom/VanillaReimplementation The implementation is already fully functional for basics servers (such as PVP-box, lobby, building) but not much for survival solely because I miss a proper pathfinding library (if someone is willing to make one, it'll be appreciated) List of features that I do need to implement (with possibly your help): https://trello.com/b/4ysvj5hT/minestom Here an example of having a lot of players without lag: My custom block system: The event system: (BTW you can see that the 64 stack limit has been shifted) Now, taking a look at my library, which is then a "Minecraft server creator library" is made to be easy to use but offers a lot of freedom. I'll take my demo package as an example. Here the main class: https://github.com/TheMode/Minestom/blob/master/src/main/java/fr/themode/demo/Main.java The instance creation: https://github.com/TheMode/Minestom/blob/master/src/main/java/fr/themode/demo/PlayerInit.java#L34 The event system: https://github.com/TheMode/Minestom/blob/master/src/main/java/fr/themode/demo/PlayerInit.java#L92 Well if you have any other questions, I'll be happy to answer them. I am taking this project at heart and plan to finish it one day. BTW I'm also using this post as a recruitment opportunity, so if you saw the Trello and are interested, feel free to contact me.
