[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/212 ... lnodes.zip
BTW in 0.4.11 debug (F5) tells which node you're pointing at if you want to identify them

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,
})

In the foreground is minetest_game, and the background is with moreblocks included





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)?

Code: Select all

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

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...

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 ipairs(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

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

		local p = {x=curX, y=curY, z=curZ}
		manip:read_from_map(p, p)
		minetest.env:add_node(p, {name=key})

		local rowCount = rowCount + 1
		
		if rowCount > curRowMax then
			rowCount = 1
			curRowMax = curRowMax + 2
			startX = startX - 1
			startZ = startZ - 1
			curY = curY - 1
			curX = startX
			curZ = startZ
		else
			curX = curX + 1
			curZ = curZ + 1
		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,
})

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.)
