Hi Zangetsu, of course it is possible but would be a lot of work to do soI wanted to ask if it is possible to add additional structures to the worldgen.
Also how does the best structure look like? I think it also wouldn't be used by many player.
So, I'm sorry but have no time for implementing this (unless you give me 1000$ ). But you are free to change the source code of the mod and include it yourself.
However I think there are better ways to do this.
Those structures are stable. They would look equal each time you play, or?
For this you can use e.g. Cheat Sheet mod. It has a painting function. This allows you to store structures and replace them anywhere else.
It has also the function to share structures with other player. It also includes NPC bases. Didn't knew about this function before creating it.
I can't remember the name of the mod but I'm pretty sure there exists a mod which allows you to build a hellevator and a arena (maybe some more structures).
If I remember correct you could craft them like other items and If you place them it generates the whole structure.
Edit: Luiafk Mod
