[mod] Display All Installed Nodes (for design and building)

[dgm5555]

The code excludes lava water and fire from display (else it obscures your view, or combusts everything)
just paste it into an init.lua file in a directory of your choice, or extract the zip file
https://dl.dropboxusercontent.com/u/21225632/displayallnodes.zip
BTW in 0.4.11 debug (F5) tells which node you're pointing at if you want to identify them

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 displayAllNodes = function(pos)
   local nodeCount = 0
   -- key is node name, eg default:stone   value is definition table
   for key, value in pairs(minetest.registered_nodes) do
      print (key)         
      nodeCount = nodeCount + 1
   end

   local manip = minetest.get_voxel_manip()
   minetest.chat_send_all("placing".. nodeCount.. " nodes")

   local curY = pos.y + math.sqrt(nodeCount * 2)
   local curX = pos.x
   local curZ = pos.z
   local startX = pos.x
   local startZ = pos.z
   local curRowMax = 1
   local rowCount = 1

   for key, value in pairs(minetest.registered_nodes) do         

      if ((string.find(key,"lava") == nil) and (string.find(key,"fire")) == nil and (string.find(key,"water") == nil) and (string.find(key,"air") == nil)) then
         local p = {x=curX, y=curY, z=curZ}
         manip:read_from_map(p, p)
         minetest.env:add_node(p, {name=key})
         -- use the voxelmanip to fix lighting problems
         manip:calc_lighting()

         rowCount = rowCount + 1
      
         if rowCount > curRowMax then
            rowCount = 1
            curRowMax = curRowMax + 1   --2
            --startX = startX - 1
            startZ = startZ - 1
            curY = curY - 1
            curX = startX
            curZ = startZ
         else
            curX = curX + 1
            curZ = curZ + 1
         end
      end
   end
   return true
end

minetest.register_chatcommand("/dan", {
   params = "",
   description = "Display All registered Nodes",
   func = function(name, param)
      local pos = minetest.get_player_by_name(name):getpos()
      pos.x, pos.y, pos.z = math.floor(pos.x + 0.5), math.floor(pos.y + 0.5), math.floor(pos.z + 0.5)

      displayAllNodes(pos)
      return true
   end,
})

EDIT: This was my original post, left for posterity

I'd really like a mod which can place every registered node in a game so I can view them.
I'm considering making one, but don't know how to list all registered nodes.
I know there is minetest.registered_nodes[nodename], but that's indexed by name. As a start, I want a list I can iterate through to return the names.
Does anyone know how to do that (or can supply code to get me more or less of the way along)?

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

for key, value in ipairs(minetest.registered_nodes) do
      -- key is node name, eg default:stone
      -- value is definition table
end


[Bas080]

I could use this when working on my OCD texture/nodebox-pack. Could you place the node in a slanted/diagonal fassion. The same way you often see when texture packs are presented? Or was that not your intention for this mod?

[dgm5555]

This is my code to create the chat command ('/dan')
It should create an inverted pyramid starting above the players head and going out and down, but
Unfortunately the for loop doesn't work, it returns a node count of 0, so I'm no further on...

try pairs rather than ipairs, maybe (ipair cancels when it gets to nil)

[dgm5555]

That worked. thanks - and dropped a pillar of lava on my head :-(
The code now excludes lava and water from display
just paste it into an init.lua file in a directory of your choice

Strangely beautiful.

[rubenwardy]

BTW, you could write

local function display_all_nodes()

It does the same - assigns the function to a local variable.

[Hybrid Dog]

it tells me "placing3616 nodes", these nodes appear but then saplings and other stuff grows

[dgm5555]

the mod just places blocks. if they've got abms (which i would have thought saplings probably have) they will then do whatever they'd normally do after being placed (eg grow.)
