Detect and run code if mouse.hit.position is nil

Help and Feedback Scripting Support
#1

Basically i need to run code if CFrame.new(mouse.Hit.Position) is nil in separate if function to not let errors and bugs break gameplay.
Heres some barebones script you can use to understand what i mean:
local dir = CFrame.new(mouse.Hit.Position)
if [idk what to put there to run if "dir" is nil] then
[code]
else
[code if its not nil]
end

I don’t think that mouse.Hit or mouse.Hit.Position can be nil, but if you want you can either wrap it in a pcall like

pcall(function()
 local dir = CFrame.new(mouse.Hit.Position)
 --code if its not nil
end)

or do

local hit = mouse.Hit
if hit then
 local dir = CFrame.new(mouse.Hit.Position)
 --code if its not nil
end

simply make:

if mouse.Hit then
--code

end

To check if a value is nil you can simply compare to it!

local dir = CFrame.new(mouse.hit.Position)
if dir == nil then
    -- dir is nil
else
    -- dir was not nil
end

Hope this helps!

You can just do

if mouse.Hit == nil then
blah blah blah
end

Worked for me when I was working on a game
