[Mod] Lava Restrictions [lavamod]

[LandMine]

Info
This is a simple mod made by PilzAdam, i asked him if he was going to release it, he said i can do it so i will. Anyhow this mod is only useful for servers.

What this mod does is, it doesnt allow lava to be placed above sea level, that means no one will be able to place lava above 0 on the Y axis. This mod came in handy on my creative server, and i think it will help others as well.

+1, awesome idea. I am going to remove my lava protection logic from skyblock in favor of this.

please include license, and pretty please host code on github...

Also, please consider when you override nodes, you should do it like this:
https://gist.github.com/3815683

The reason is that other mods may also override this same node, this will allow both changes without conflict, and is also a lot less code. Here is how I think the mod should look:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

local lava = {}
for k,v in pairs(minetest.registered_nodes["default:lava_source"]) do lava[k] = v end
lava.on_construct = function(pos) if pos.y >= 0 then minetest.env:remove_node(pos) end end
minetest.register_node(":default:lava_source", lava)


Neat, right?

Ok added licence and added the git page PilzAdam provided me. Fork it and make the changes if you wish :)

Create a new mod folder and write those codes into a new init.lua file.

Need to add to the mod folder this file depends.txt:

Ups.
To place lava_source block — works.
Pour the lava from a bucket — is not working.

To place lava_source block — works.

Because you can place it in singleplayer, but not in multiplayer. Just remove the 'if minetest.is_singleplayer() then' from the codes.

No. I've checked the mod in multiplayer. If you do better, then it will be fine. Video http://youtu.be/hHalR9sMp-w

I did this::

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.override_item("default:lava_source", {
   on_construct = function(pos)
      if pos.y >= 0 then
         minetest.env:remove_node(pos)
      end
   end
})

Oh yes. I totally forgot about the buckets. Thanks for sharing your codes.
