How to properly use PCall in this situation?

Asked 1,058 views1 answers

Hey there,

I'm currently having issues using pcall properly. My loadstring is executing, but without the argument provided, and not functioning properly. Here's what I'm up to:

function confirmCommand(gameCommand)
	local success, message = pcall(execCommand(gameCommand)) -- line 32
	if success then
	else
		print("An error occured: " .. message)
	end
end

function execCommand(executedCommand)
	loadstring(executedCommand)
end

This is the "secret" script, which is another error I get. It says error loading module yet it still works each time.

require(game.Workspace.Module)

Yes, it's one line.

Here are the errors I receive each time:

14:30:21.559 - Requested module experienced an error while loading
14:30:21.559 - Stack Begin
14:30:21.559 - Script 'Workspace.secret', Line 1
14:30:21.560 - Stack End
14:30:21.560 - Workspace.Module:32: bad argument #1 to 'pcall' (function expected, got no value)
14:30:21.560 - Stack Begin
14:30:21.561 - Script 'Workspace.Module', Line 32 - global confirmCommand
14:30:21.561 - Script 'Workspace.Module', Line 18 - global checkCommand
14:30:21.561 - Script 'Workspace.Module', Line 76
14:30:21.562 - Stack End

Does anyone know what I'm doing wrong?

With pcall the arguments that will be passed to the function needs to be separate.

E.g :-

function confirmCommand(gameCommand)
    local success, message = pcall(execCommand, gameCommand) -- function then arguments to be passed
    if success then
    else
        print("An error occured: " .. message)
    end
end

function execCommand(executedCommand)
    loadstring(executedCommand)
end

Hope this helps.
