How to delay something?

[DrKittyWaffles]

preserve the value of x before it is set again.

local x = 5
local y = x

delay(2, function()
    print(y * 2)
end)

x = 12

Not sure why you are doing this. Also I suggest using coroutine or or something else instead of delay as suggested by @Interaxis.

Coroutines V.S. Spawn()... Which one should I use?

The title says it all… Basically I want to know in what scenarios I should use: spawn(function() -- Script end) And what scenarios I should use: local thing = coroutine.create(function() -- Script end) coroutine.resume(thing) So… When is it best to use spawn(function() and when it is best to use coroutines?
