How to use coroutine.wrap

Help and Feedback Scripting Support
#1

example:

local function BindToSave(Plr)
–saving stuff–
end

game:BindToClose(function()
for i,v in pairs(game.Players:GetChildren()) do
coroutine.wrap(BindToSave(v)())
end
end)

is this right?

#2

i just wanna know if im using the coroutine.wrap the right way

#3

The function and the argument are separated when using coroutine.wrap. Correct way to use it in this case is coroutine.wrap(BindToSave)(v)

#4

Sure, but why wouldn’t using task.spawn be better?

#5

why? and what is that can you give example? is it the same as spawn(function() end)

#6

quick question, it will run instantly unlike coroutine.create right?

#7

task.spawn is the newer version of spawn.

It creates a coroutine and immediately resumes it. spawn works like task.defer, which means it creates a coroutine and resumes it in the next task cycle (you could learn about how the Roblox task scheduler works but to keep this brief, I will not elaborate). But task.spawn resumes it immediately.

The following two pieces of code execute identically:

coroutine.wrap(f)()

task.spawn(f)
#8

coroutine.wrap is just a wrapper for coroutine.create. As in, it works like this:

function coroutine.wrap(f)
    local co = coroutine.create(f)
    return function(...)
        return coroutine.resume(co, ...)
    end
end
#9

last question about the example you showed,
in my case i should use task.spawn(BindToSave(v)) right?

#10

Close, but not quite.

The arguments for task.spawn are:

  • thread or function - Thread to spawn
  • … (varargs) - Arguments to pass into rhat function

What you are doing is calling BindToSave with v and passing the return value (I assume nil) into spawn.

Instead, try this:

task.spawn(BindToSave, v)

got it, thanks il use that instead
