May i ask, whats xpcall? Whats the use ofmxpcall?

#5

It’s pcall but it gives you an argument which is a function , and it runs it when it errors.

Opcall is xpcall but with the success arg, and I also believe it’s faster than xpcall as it’s using pcall.

#6

Oh yeah and for opcall read this code sample

#13 
function opcall(functiontorun, functiontorunonsuccess, functiontorunonerror)
	local result
	-- running function
	local success,err = pcall(function()
		result = functiontorun()
	end)
	
	if success then
		-- worked
		print("the result is:", result)
		functiontorunonsuccess(result)
	else
		-- failed
		functiontorunonerror(err)
	end
	return success,err
end

-- calling function
local succ, err = opcall(
	function()
		return 1 + 2 == 5
	end,
	function(result)
		print(result)
	end,
	function(err)
		print(err)
	end
)

Made it so you can return and get the result and also removed some code that isn’t needed

Ig nice code. I really could’ve used assert lol.

#19

Also, assert does huge memory consuming. I suggest you do the disgusting ifs.

#20

I made a version of this but with ternary.(the fake ternary)

function opcall(functiontorun,functionerr,function success)
local success,err = pcall(function()
functiontorun = functiontorun()
end
success == true and functionsuccess(success) or functionerr(err)
end

I really like one liners, but I didn’t test it yet so I don’t think it work

#21

Can I get the source of this information? Never heard of assert being memory intensive.

#22

Here.
