FOSS gamedev and creative worlds

I am creating a mod where you can craft a block that takes over your world, I need some textures, the link to the texture requests is here. I will try to upload screenshots as soon as I have something worth showing.

Questions:
1. How to register a node that is unbreakable?
2. for this code, how to make it so that neigbors are all blocks? Do I just delete that line or do I put something there?

3. How do I make a schematic (see instabuild or something) ? I need this because the only purified block is going to be inside, and i need this building to spawn somewhere random in the currupted region



Corrupted Block for now: (NOT PERMANENT!!!)

1) The lua_api found in minetest/docs explains how to make nodes unbreakable.

2) You may want to look into how dirt with grass works.

Ok another question, Is there a group that is all nodes, like opposite of nil?

sure, like

node ~= nil

done

From https://github.com/celeron55/minetest/blob/master/doc/lua_api.txt :

neighbors = {"default:water_source", "default:water_flowing"}, -- (any of these)
^ If left out or empty, any neighbor will do

If you want to be sure that a node is actually a node (and not nothing), you might use node=minetest.get_node(pos), and then compare node.name to "air" (nothing) or "ignore" (not generated) :P

This document is outdated. Use https://github.com/minetest/minetest/blob/master/doc/lua_api.txt instead.

I am sorry, I wrote my question wrong, what I meant to say is for registering abms, could the nodenames part select everything because does not seem to work. Also for future developing, I am thinking of tree corrupted blocks, and cactus corrupted block so could I put something like
