Creating a PiMUD Game -*Accepting Help*-

Since my knowledge is limited to Java I've been trying to teach my son how to code. Hopefully, get him into it.

I had a large amount of trouble trying to figure out how to get the Jackson files for JSON coding. I have no idea if I'm using the terminology correctly.

I'm at the point where the Server starts, a new map generates each time I load in. I'm a bit on the spectrum so let me list out what I'm working on next.

1. I have to make the map a constant upon each load for world design
2. Grid the map so each area can be identifiable
3. Create a command list for basic character manipulation
4. Is there a way to create the possibility for in-game game manipulation? (ie edit rooms, create npcs, items, events)
