How to set nodes as indestructible?

[Kpenguin]

Hello,
I'm working on a relatively small map. I want to create an indestructible barrier around the edges of the map so that you can't fall out of the world accidentally. How do I do this? I have the worldedit mod installed to create the barrier, but I need to know how to make it indestructible.

Thanks!

I think something like this should be enough:

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.register_node("mymod:reinforced_wall", {
   description = "Reinforced Wall",
   tiles = {"mymod_wall.png"},
   groups = {immortal=1},
   on_blast = function() end,
})

What do I do with this code?

Use this code as part of a mod you create and make the custom block type be indestructible, using "immortal=1".

The proper way is not defining groups at all, or define a non-standard group that can only be destroyed by special (mod-provided) tools. `immortal` group is not really special for nodes (it does make entities immortal though), but it falls into the second option.

I tend to use the {unbreakable = 1} group to stop dungeon masters in mobs redo from destroying blocks, and it is also used in lucky blocks so that those same blocks do not blow up.

Also in tnt mod they add this code to node registry to stop blasts destroying nodes as well:

on_blast = function(pos, intensity)
end,

It turns out, making a node indestructible is trickier than you might think. There is not a single setting which makes a node indestructible.
Luckily, this is a problem I have already solved in practice. I use it for my mod “bedrock2”.

Here's a node definition template you can (and should) use:
