Edit: using Minetest 0.4.9 on an Ubuntu system.

Hi there,

how do I access the functions of a mod?
For example the tube_item function of pipeworks.

My mod, at this point, simply consists out of these 2 files.

depends.txt:

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: default pipeworks

init.lua:

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: print("pipeworks is: "..dump(pipeworks))

this prints:

pipeworks is: nil

So, where do I get that pipeworks object from?

Thanks in advance.

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: if minetest.get_modpath("pipeworks") ~= nil then --pipeworks exists pipeworks.tube_item(pos, item) end

pipeworks must be enabled in the world, else it won't work.

EDIT: Oh, welcome to the minetest forums!

Thank you for the welcome.

pipeworks is enabled.
I've changed the code to

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: if minetest.get_modpath("pipeworks") ~= nil then print("pipework exists") if pipework == nil then print("but is nil") else print("and is not nil") end else print("pipework does not exists") end

Output is now:

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: pipework exists but is nil

You made a typo there, it's actually "pipeworks"

EDIT: The

I gave you, is useless in this case because pipeworks is in depends.txt

Changed the code to:

Output is still:

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: pipeworks exists but is nil pipeworks is: nil

Actually I've grabbed the code I am fiddling with from
technic/machines/register/common.lua:

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: function technic.send_items(pos, x_velocity, z_velocity) -- Send items on their way in the pipe system. local meta = minetest.get_meta(pos) local inv = meta:get_inventory() local i = 0 for _, stack in ipairs(inv:get_list("dst")) do i = i + 1 if stack then local item0 = stack:to_table() if item0 then item0["count"] = "1" -- Sane -> this fails local item1 = pipeworks.tube_item({x=pos.x, y=pos.y, z=pos.z}, item0) item1:get_luaentity().start_pos = {x=pos.x, y=pos.y, z=pos.z} item1:setvelocity({x=x_velocity, y=0, z=z_velocity}) item1:setacceleration({x=0, y=0, z=0}) stack:take_item(1) inv:set_stack("dst", i, stack) return end end end end

Updating to mt 0.4.10 solved the problem.
