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