What does the parameter of Pcall Do I don't understand where it saids func,tuple args?

Asked 206 views1 answers

So I stumbled across the parameters of PCALL and wondered how I can use it

it saids first parameter is function and the other one is a tuple

but I don't have a idea on how to use it

For Example 

local DataStoreService = game:GetService("DataStoreService")
local myDataStore = DataStoreService:GetDataStore("DataStoreName")



-- getting data
local success, result = pcall(DataStoreService.GetAsync, DataStoreService, "Gay")

if success then
   print('G')

 -- do something to result
else
    -- result is the error message
end

But if I tried 

DataStoreService.GetAsync

Outside Pcall it would error

The other arguments to pcall will be the ones used as arguments in the function assigned to said pcall's first parameter. Here's an example to better explain what I mean by that:

-- The function to be called
function OnPcall(string1, string2, string3)
	return string1 .. " " .. string2 .. " " .. string3
end

-- "Hello", "my" and "friends!" will be passed to our function OnPcall
local success, message = pcall(OnPcall, "Hello", "my", "friends!")
if success then
	print("Message: " .. message)
else
	warn("Error: " .. message)
end
