How can I reference the "original" key/value pair in a recursive function?
I have a my function called tableRec. I added the level variable with the help of len_ny. However it seems the script still won't distinguish the levels of recursion, as the output doesn't print when the level 3 has been reached, and trackPoint remains as nil, causing an error.
module.tableRec = function(tab, func)
if type(tab) ~= "table" then return end
local level = 0;
for i, v in pairs(tab) do
level = level + 1
func(i, v, level)
module.tableRec(v, func, level)
end
end
functions.tableRec(module, function(a, b, lvl)
local trackPoint
if lvl == 3 then
print("level 3 of recursion has been reached")
trackPoint = b
end
if a == "Sensor" then
functions.tableRec(module, function(i, v, level)
local adjacentBlock
if level == 1 then
adjacentBlock = v
end
if i == "Sensor" then
if v == trackPoint.Sensor then
trackPoint.Adjacent = adjacentBlock
end
end
end)
elseif a == "PathOptions" then
for i = 1, #b do
b[i].Status = Instance.new("IntValue")
end
end
end)

Please provide explanation with your answers. Simply posting code does not spread knowledge of integral scripting processes which helps people understand the logic and reasoning behind your answer.
module.tableRec = function(tab, func)
if type(tab) ~= "table" then return end
local level = 0;
for i, v in pairs(tab) do
level = level + 1
func(i, v, level)
module.tableRec(v, func, level)
end
end
functions.tableRec(module, function(a, b, lvl)
if lvl == 2 then
print('level 2 of recursion reached !!')
end
if a == "PathOptions" then
for i = 1, #b do
b[i].Status = Instance.new("IntValue")
end
end
end)
its pretty simple but i could see how it could be a problem, good luck on your adventures!

Wow, i refrained from doing that at first because I thought it would make a new "level" variable for each table it went through. Thanks! Trew86 175 — 5y
