Programming a in game world editor because i am too lazy to create server code for axiom or other tools

Context
I am creating a custom mini game server for Minecraft with Minestom
A library allowing to write a java Minecraft server from scratch

Today i spent most of my time building a in game world editor functioning similar to the popular world edit plugin.

My little twist is that i use the new displayblocks Minecraft offers to make a visual appealing selection box of what you selected. It is ridicules how long it took me >:(

I also made it possible to load specific worlds and edit them which are saved after you are finished this way i could for example modify the TntRun game world a bit to my liking while the server runs but these modifications made are permanent. Normally worlds don’t get saved after the mini game is finished.

So now i could just rely on my own tools instead of having to create a world in vanilla Minecraft and then import them into my Minestom project.

I also touched the idea of trying to implement protocol code of Luanti or formally known as Minetest which works with Minestom to let players join through Minetest for people who don’t want to use proprietary applications or don’t have an account for regular Minecraft. But i will probably fail at that task because it is waaay over my head :|
