Tween sequence "Argument 3 missing or nil"

Help and Feedback Scripting Support
#1

I have a script that’s suppose to tween the player’s camera between 2 objects using a sequence, but I always get the error “Argument 3 missing or nil” when trying to use sequences.

local TweenService = game:GetService("TweenService")
local Camera = workspace.CurrentCamera
Camera.CameraType = Enum.CameraType.Scriptable
local TweenToPlayer = game.Players.LocalPlayer.Character:WaitForChild("UpperTorso").CFrame
local TweenToEnemy = game.Workspace.NormalFightingRingKlein.Enemies["Alvin Kleid"]:WaitForChild("UpperTorso").CFrame

local tweenInfo = TweenInfo.new(
	2, -- Time to get to objective
	Enum.EasingStyle.Quart,
	Enum.EasingDirection.InOut,
	0, -- RepeatCount
	false, -- Reverses
	0.5 -- DelayTime
)

local GameStartTweenSequence = TweenService:Create(Camera, tweenInfo)
GameStartTweenSequence:Create(Camera, {CFrame = TweenToPlayer})
GameStartTweenSequence:Create(Camera, {CFrame = TweenToEnemy})


local function onRoundStart1()
	GameStartTweenSequence:Play()
	GameStartTweenSequence.Completed:Wait()
	
	local new = game.ReplicatedStorage.RoundPopup1:Clone()
	new.Parent = script.Parent.PopupGuiGym
	print("Round 1 started!")
end

Hi, I’m a little bit confused on what your trying to do. You can’t create a tween then create a tween using that tween again.

To create a tween you should do this:

TweenService:Create(Camera, tweenInfo, {CFrame = TweenToPlayer})

If your trying to string together multiple tweens, just create multiple tween variables:

local Tween1 = TweenService:Create(Camera, tweenInfo, {CFrame = TweenToPlayer}
local Tween2 = TweenService:Create(Camera, tweenInfo, {CFrame = TweenToEnemy}

Tween1:Play()
Tween1.Completed:Wait()
Tween2:Play()

This is just a simplified version

The problem is that it needs to all be 1 long animation that tweens between the 2 objects, but it takes a small break in between tweens.

hmm, maybe instead of using.Completed:Wait(), just use a task.Wait() and set it to 1.9, then start the next tween before the first one finishes to link them more closely.

like this:

local Tween1 = TweenService:Create(Camera, tweenInfo, {CFrame = TweenToPlayer}
local Tween2 = TweenService:Create(Camera, tweenInfo, {CFrame = TweenToEnemy}

Tween1:Play()
task.wait(1.9)
Tween2:Play()

You could also adjust you tweenInfo (the tweenStyle) for a smoother transition between the tweens

Doing this just does the same thing but cuts off the animation early.

Ohhh sorry, Scratch what I just said and go back to what you had before. Its because you have a delay within you tweenInfo. Just remove it or set it to 0.

local tweenInfo = TweenInfo.new(
	2, -- Time to get to objective
	Enum.EasingStyle.Quart,
	Enum.EasingDirection.InOut,
	0, -- RepeatCount
	false, -- Reverses
	0.5 -- DelayTime   <---- Get rid of this or make it 0 <----
)

Does the same thing but doesn’t linger on the target object like I want it to.

#8

So you want it to stop on the player then continue to the other player? Isn’t that what you had?

#9

Removing the delay would get rid of the small break in between the tweens

Found the solution:

local tweenInfo = TweenInfo.new(
	2, -- Time to get to objective
	Enum.EasingStyle.Quart,
	Enum.EasingDirection.InOut,
	0, -- RepeatCount
	false, -- Reverses
	0.5 -- DelayTime
)

local Tween1 = TweenService:Create(Camera, tweenInfo, {CFrame = TweenToPlayer})
local Tween2 = TweenService:Create(Camera, tweenInfo, {CFrame = TweenToEnemy})


local function onRoundStart1()
	Tween1:Play()
	Camera.CameraType = Enum.CameraType.Scriptable
	Tween1.Completed:Wait()
	Tween2:Play()
	Tween2.Completed:Wait()
	Camera.CameraType = Enum.CameraType.Custom
	
	local new = game.ReplicatedStorage.RoundPopup1:Clone()
	new.Parent = script.Parent.PopupGuiGym
	print("Round 1 started!")
end
