It returns 2 things, if the function ran without errors or not true or false and the result the function gives or the error string if it errored. A pcall is a protected call, meaning that the function is run in protected mode and any errors do not affect the main code. It takes two arguments, func which is a function and args which is a tuple.

It also returns two values: A bool one and a variant one. When the bool value is false error in the code , the variant value will contain the error that can be displayed with orange text in output using warn function. You can use the return function if you want to store data from the script into the universal variable. The most popular use of pcall is data storing because functions like GetAsync or SetAsync are network calls and they can generate an error. I recommend reading Lua Globals because there is a short description for some functions and variables for pcall and xpcall too , the rest is in Roblox Globals.

A coroutine is used to perform multiple tasks at the same time from within the same script. Such tasks might include producing values from inputs or performing work on a subroutine when solving a larger problem. A task doesn't even need to have a defined ending point, but it does need to define particular times at which it yields pause to let other things be worked on. A new coroutine can be created by providing a function to coroutine. Once created, a coroutine doesn't begin running until the first call to coroutine.
