Hi,
I'm new too, but I would try that:
Code: Select all
local nbrSlots=#chest.get_inventory(defines.inventory.chest)
local nbrEmptySlots=0
for i=1,nbrSlots,1
do
if chest.get_inventory()[i]==nil then
nbrEmptySlots=nbrEmptySlots+1
end
end

to get the chest variable, there are some example functions in Factorio\data\base\lualib\
file "check.lua" :
Code: Select all
check.chests_emptied = function(chest_list, goal, update_quest_gui)
if update_quest_gui == nil then
update_quest_gui = true
end
goal = goal or #chest_list
-- Check each entity by tag in the list
local result = {total=0,current=0}
for _, tag in ipairs(chest_list) do
local chest = locations.get_surface_ent_from_tag(locations.get_main_surface(),tag)
if chest then
local inventory = chest.get_inventory(defines.inventory.chest)
result.total = result.total + 1
if inventory and inventory.is_empty() then
result.current = result.current +1
end
end
end
if update_quest_gui then
quest_gui.update_count('empty',result.current,goal)
end
return result.current >= goal
end
file "player_tracker.lua":
Code: Select all
tracker.check_chest_for_items = function(item_list,quant)
local chests = locations.get_main_surface().find_entities_filtered({name='wooden-chest'})
for _, chest in pairs(chests) do
local inv = chest.get_inventory(defines.inventory.chest)
for _, item_name in pairs(item_list) do
if inv.get_item_count(item_name) > quant then
print("found chest of iron")
tracker.start_timer('full_item_chest')
return chest
end
end
end
return nil
end
