Hey guys I need some help:
I want to create a mod with a chat command that places a block on a position, but I have no idea how to do that. The idea behind that is that it would be very useful in creative mode if you use the singlenode mapgen (currently I always have to use worldedit to do that).

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: in general: /placeblock modname:nodename x,y,z example: /placeblock default:stone 10,15,10

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: /placeblock default:stone 10,15,10

given: player name and param ("default:stone 10,15,10")

Now let's split this param string:

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 args = param:split(" ")

-> Outputs an array: { "default:stone", "10,15,10" }

Now split the 2nd element into numbers:

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 arg_pos = args[2]:split(",") local pos = { x = tonumber(arg_pos[1]), y = tonumber(arg_pos[2]), z = tonumber(arg_pos[3]) }

And the final code:

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 args = param:split(" ") if #args ~= 2 then return false, "Wrong arguments" end local arg_pos = args[2]:split(",") if #arg_pos ~= 3 then return false, "Wrong arguments" end local pos = { x = tonumber(arg_pos[1]), y = tonumber(arg_pos[2]), z = tonumber(arg_pos[3]) } minetest.set_node(pos, { name = args[1] })

lf you use worldedit and don't want to have to type the commands, you could use the chatcommand tool making it execute the chatcommands "//pos1", "//pos2" and "//set default:cobble" when using it.

@Krock:
Thx for that code that helps a lot! :D

@Hybrid Dog:
Thx, but I was just looking for a simple way to place a single block in the air. :)
