Tip on Lua controlled Tube (use for sorting)
Posted: Sat Sep 01, 2018 14:51
When playing minetest, I like to have an automatic sorter:
The tubes are event driven, so I need to react to events. Here is an example of my first Lua controlled tube after my incoming chest:
The Lua controlled tubes have colored connections, and you simply return the color of where you want the specific item to end up.
The second Lua controlled tube is done like this:
Here you already see the use of idiom to test on substrings. I use this because them item name sometimes changes, e.g. the drill has several modes of operation. So I only search at the start of the string for the decision if the item should go to the battery box for recharging.
Substrings can also be used to have chests that get items from a whole mod. With normal pneumatic sorter tubes this is almost impossible, they only can select by 6 items. But to check if an item is from a mod is a single instruction in Lua:
- * I put all my mined thing into a chest
* a stackwise Filter-Injector pulls them out, powered by a blinky plant
* then things go into a sorter network
* exits are of course grinder, furnace, centrifuge, battery box (to recharge), workshop
* and of course lots of chests
The tubes are event driven, so I need to react to events. Here is an example of my first Lua controlled tube after my incoming chest:
Code: Select all
if event.type == "item" then
local s = event.item.name
-- grinder
if s == "default:copper_lump" or
s == "default:gold_lump" or
s == "default:iron_lump" or
s == "forge:slag" or
s == "moreores:mithril_lump" or
s == "moreores:silver_lump" or
s == "moreores:tin_lump" or
s == "technic:chromium_lump" or
s == "technic:uranium_lump" or
s == "technic:zinc_lump" or
s == "technic_aluminum:alumina_lump" then
return "green"
end
-- furnace
if s == "forge:slag" or
s == "mobs:rotten_flesh" or
s == "technic:chromium_dust" or
s == "technic:copper_dust" or
s == "technic:gold_dust" or
s == "technic:mithril_dust" or
s == "technic:silver_dust" or
s == "technic:tin_dust" or
s == "technic:wrought_iron_dust" or
s == "technic:zinc_dust" or
s == "technic_aluminum:aluminum_dust" or
s == "technic_aluminum:bauxite_lump" then
return "black"
end
-- small centrifuge
if s == "technic_aluminum:alumina_dust" then
return "yellow"
end
return "red"
endThe second Lua controlled tube is done like this:
Code: Select all
if event.type == "item" then
local s = event.item.name
-- workshop
if s == "bones:bone_scythe" or
s == "cottages:hammer" or
s == "default:axe_diamond" or
s == "default:axe_mese" or
s == "default:pick_diamond" or
s == "default:pick_mese" or
s == "default:axe_diamond" or
s == "default:axe_mese" or
s == "default:hoe_diamond" or
s == "default:hoe_mese" or
s == "default:shovel_diamond" or
s == "default:shovel_mese" or
s == "default:sword_diamond" or
s == "default:sword_mese" or
s == "technic:treetap" or
s == "technic_aluminum:sword_aluminum" or
s == "screwdriver:screwdriver" or
s:sub(1,8) == "3d_armor" or
s:sub(1,6) == "shield" or
s:sub(1,9) == "stairpick" then
return "black"
end
-- charger
if s == "technic:chainsaw" or
s == "technic:prospector" or
s == "technic:sonic_screwdriver" or
s == "teletool:teletool_technic" or
s:sub(1,13) == "technic:laser" or
s:sub(1,20) == "technic:mining_drill" then
return "yellow"
end
-- go-box
if s == "bridgetool:bridge_tool" or
s == "carts:cart" or
s == "default:torch" or
s == "default:ladder_wood" or
s == "farming:corn" or
s == "landrush:landclaim" or
s == "more_chests:wifi" or
s == "protector:protect" or
s == "travelnet:elevator" or
s:sub(1,11) == "bridgetool:" then
return "white"
end
--- sort1
return "red"
endCode: Select all
s:sub(start,end)Substrings can also be used to have chests that get items from a whole mod. With normal pneumatic sorter tubes this is almost impossible, they only can select by 6 items. But to check if an item is from a mod is a single instruction in Lua:
Code: Select all
if event.type == "item" then
local s = event.item.name
if s:sub(1,7) == "technic" then
return "black"
end
return "red"
