How can I call a funtion two times without waiting for it to finish?

Hello, I have been working on my game and I had to call a finciton 3 times so I did:

    viewport(petdisplay, chosenPet:Clone())

    viewport(petdisplayRight, chosenPet:Clone())

    viewport(petdisplayLeft, chosenPet:Clone())

The function is a normal function but it has some waits in it and I was wondering how can I skip that wating time ?

Thank you !

spawn(function()
--function in here
end)

someones going to say use couroutines but idk how (this is how i do it)

Coroutines! Read about them here

Thank you ! But how can I name the function with spawn()

#5

That is the same as

coroutine.wrap(function()

end)()

or

coroutine.resume(coroutine.create(function(l

end))

local function func()

Don’t call the function. Just insert it as a parameter.

local function func()

end
spawn(func)

And how do I send a parameter in the function with that ?

Using coroutine, you can do:

function foo(someString)
   print (someString)
end

local newCoroutine = coroutine.wrap(foo)

newCoroutine("Hello, World!")

You can’t. You would have to use coroutines which pretty much have the same result.

local function func(number)
print(num)
end
coroutine.wrap(func)(3)

And to call it 2 times I do this ?

 local newCoroutine = coroutine.wrap(viewport)
 newCoroutine(petdisplay, chosenPet:Clone())
 newCoroutine(petdisplayRight, chosenPet:Clone())

It gives me an error when I call it 2 times here is my code:

game.ReplicatedStorage.Remotes.TripleHatchClient.OnClientInvoke = function(eggName)
    local module = require(workspace.Eggs:FindFirstChild(eggName).Rarity)
    local chosenPet = module.randPet()
    local chosenPet2 = module.randPet()
    print(chosenPet2)
    local egg = workspace.Eggs:FindFirstChild(eggName)
    renderEgg(egg, middleEgg)
    renderEgg(egg, leftEgg)
    renderEgg(egg, rightEgg)
    middleEgg.Visible = true
    leftEgg.Visible = true
    rightEgg.Visible = true
    script.Parent.Parent.Main.Enabled = false
    wait(eggSpeed)
    middleEgg.Visible = false
    leftEgg.Visible = false
    rightEgg.Visible = false
    local newCoroutine = coroutine.wrap(viewport)
    newCoroutine(petdisplay, chosenPet:Clone())
    newCoroutine(petdisplayLeft, chosenPet2:Clone())
    
    template(chosenPet)
    petdisplay.Visible = true
    return chosenPet
end

The print works so it does not return nil but it gives me an error saying attempt to call a nil values (without the line where the error is).

You can’t store a coroutine if you want it to run at the same time.

Instead of

Do

coroutine.wrap(viewport)(petdisplay, chosenPet:Clone())
coroutine.wrap(viewport)(petdisplayLeft, chosenPet2:Clone())

If you want them to run simultaneously, you’d have to write different coroutine.wraps. Instead of declaring the wrap as a variable call them each individually:

coroutine.wrap(viewport)(arg1, arg2, ...)
coroutine.wrap(viewport)(arg1,arg2,...)

Otherwise it’ll wait for the first thread to finish and then run the second call
