So i am trying to create a inventory system using tables. I can add new array elements to the inventory but i have ran into a problem with removing them. Since the way i remove the array element is by using it’s index and the way i get the index is by getting it from the text buttons name.
The problem that i have run into is that sometimes the inventory table index and the text button name can become mismatched which would result in stray elements being left in the inventory table.
The solution i want to implement is renaming the text buttons name to the number of them remaining but i have no idea how. Kinda like this:
Well, here’s an example with a table of numbers I created (you’ll want to change this to your uses)
local numbers = {1, 2, 10, 4}
function fixnumbers()
local missing = {}
table.sort(numbers, function(a, b)
if not b then return false end
return b > a
end)
for i,v in pairs(numbers) do
if not table.find(numbers, v+1) and i < #numbers then
table.insert(missing, v+1)
end
end
if #missing > 0 then
for i,v in pairs(numbers) do
for a, missing in pairs(missing) do
if v > missing then
numbers[i] -= 1
end
end
end
return fixnumbers()
else
return true
end
end
fixnumbers()
print(numbers)
The ‘table’ library already achieves this via table.remove.
local t = {1, 2, 3, 4}
table.remove(t, 3) --'table.remove' shifts all items following the removed item down one index.
for i, v in ipairs(t) do
print(i, v)
end
--1 1
--2 2
--3 4
