What is pcall? What does it do?

Help and Feedback Scripting Support

Hello! SO I’m trying to learn scripting, What is Pcall and what does it do, How does it work, and what can it be used for?

#2

A pcall will run a set of instructions, usually functions, and returns a tuple (a table/ list) containing whether the code ran errored or not, and any of the returned values if it were to have succeeded. If it didn’t succeed, however, it would return the error message. Developers tend to use pcall functions for uses such as getting/ saving data.

local success, errorMsg = pcall(function()
	local test = 1 + "A tring"
end)

print(success, errorMsg)

Output:
false attempt to perform arithmetic (add) on number and string

local success, out = pcall(function()
	local test = 2 + 10
	return test
end)

print(success, out)

Output:
true 12
