For example, say I had a string in a variable like this:
local x = "game.Workspace.Part"
Would there be a way to, for lack of a better word, remove the quotation marks from this and use it to reference something?
I couldn’t find anything about this while searching
Yes, you can split the string into words and then search for the object recursively.
function convert(path)
local position = game
local path = string.gmatch(path, '[%w%_]+');
for v in path do
if v ~= "game" then
position = position[v];
if position == nil then
error('Invalid path');
end
end
end
return position
end
local x = convert("game.Workspace.Part")
However this will only work for absolute paths, if you want relative paths to work then we would have to modify the code a bit.
I’m trying to store “Cup.Name” as a string value inside an array and use it as a reference later, the reason I’m trying to do this is because I need “Cup.Name” before Cup.Name can be defined.
Also, this is slightly of out of my skill level, so I would appreciate if you could guide me though it a bit.
I am sure that there’s no need to store anything like that in an array, can you describe why are you doing that and what is the whole use case?
You can always check if Cup is not nil and then reference Cup.Name.

This is the code, I apologise for the table being incredibly messy. The last 2 lines have the “Cup.Name”.
I attempted using BoolValues with local AddOn, but it didn’t work, that’s why I’m resorting to this method.
Can you explain what are you trying to achieve?
I’m trying to create a system that allows users to use machines to create drinks such as milkshakes, teas, and coffees. If you’ve ever played any cafe game on Roblox you’ll know exactly how it works.
I used to have 400 lines of individual functions for each item and decided to use arrays and for loops to clean it up.
The reason for the massive array is for the many recipe combinations and to allow for easy customization.
Basically, when the tool (coffee cup, milkshake, etc) is renamed, some of the new names require concatenation and I wasn’t able to use BoolValues to determine what items need concatenation.
But cup.Name = cup.Name doesn’t change the name of a cup, is there going to be another situation when you rename it to something else? (not array.product and not cup.Name)
Can’t you just do workspace[“Part”]? This is more simple than anything else. I don’t tested, but you can try this:
local x = loadstring('return function() return workspace["Part"] end')()()
I don’t think that is the best thing but I think it works well.
Enabling loadstring is not safe, there’s certainly a better way do to what the OP wants to achieve.
Sorry, the last for loop should look like this:
for _,v in pairs(array.acceptedItems) do
if array.product == "w/Sugar" then
local x = "w/Sugar"
cup.Name = array.product..x
else
cup.Name = array.product
end
end
As you can see, I run into a bottleneck here, I can’t combine Cup.Name while checking if
if array.product == "w/Sugar" then
is true or false
Also, .product was originally “w/Sugar”, but I was experimenting.
Loadstring isn’t deprecated and is still working good.
One idea that I have is to save an array of information: [workspace or other, folder.Name, child.Name, item.Name, etc.] About the item. You would then do
array[1]:WaitForChild(array[2]):WaitForChild(array[3]) and so on.
Not sure if this is the best way to do it, though.
That’s what the main array already does, stores data.
This is overly complicated, you should be storing addons in an array, for example:
local product = {productName = "", Addons = {}}
-- and for example:
product.ProductName = "Blueberry Milkshake"
table.insert(product.Addons, "Sugar")
table.insert(product.Addons, "Ice")
-- and now print it like that:
function tostringProduct(p)
local text = p.ProductName
for _,v in ipairs(p.Addons) do
text = text .. " w/" .. v
end
return text
end
print(tostringProduct(product)) -- Blueberry Milkshake w/Sugar w/Ice
I appreciate the response, but would there be a way to do this with my current system? I really don’t have the mental capacity to do this all over again.
It will be easier to modify than continue with the current system, because in the future if you would want to expand your system with new products or ingredients it will be a nightmare.
Alright, I’ll try it later, I have to go.
Regardless of whether it works or not, loadstring allows users to run arbitrary server code which means exploiters can easily modify your Datastores and run any code they want.
You can’t use loadstring on client, it will eror. So there isn’t any way to run codes and destroy your game.
