<\Problem/>

Im trying to make something where it tweens all the model at oncem, but it goes 1 by 1.

</Other Info</>

-Line of error - No error.
-Model Name - Gaster Blaster
-Script Location - game.Workspace.Gaster Blaster.Script

</>Code</>



	for i,v in pairs(script.Parent:GetChildren()) do
		
		if v:IsA("BasePart")or v:IsA('UnionOperation') then
			
			local tweenService = game:GetService("TweenService");
			
			local tweenInfo = TweenInfo.new(
				game:GetService("Players").RespawnTime - 0,
				Enum.EasingStyle.Quad,
				Enum.EasingDirection.Out
			)
			
			local goal = {
				Transparency = 0;
			}
			
			local finalTween = tweenService:Create(v, tweenInfo, goal)
		finalTween:Play()

Still does the exact same thing.

	for i,v in pairs(script.Parent:GetChildren()) do
		
		if v:IsA("BasePart")or v:IsA('UnionOperation') then
			
			local tweenService = game:GetService("TweenService");
			
			local tweenInfo = TweenInfo.new(
				game:GetService("Players").RespawnTime - 0,
				Enum.EasingStyle.Quad,
				Enum.EasingDirection.Out
			)
			
			local goal = {
				Transparency = 0;
			}
			
			local finalTween = tweenService:Create(v, tweenInfo, goal)
			spawn(function() finalTween:Play() end)
		end
	end

this might work

They shouldn’t be playing separately in general. I copied your script and I’ve had no problem with them playing one at a time. May I see the full script?

I added some minor things to make the tween more apparent, but it shouldn’t change anything.
Code I used:

local ModelChildren = workspace.Test:GetChildren()
for Index, Current in pairs(ModelChildren) do
	if (Current:IsA("BasePart") or Current:IsA("UnionOperation")) then
		local TweenService = game:GetService("TweenService")
		
		local TWInfo = TweenInfo.new(
			game:GetService("Players").RespawnTime + 20,
			Enum.EasingStyle.Quad
			--- Default easing direction is out so no need to put anything here
		)
		local Goal = {
			Transparency = 1,
			CFrame = Current.CFrame * CFrame.new(0, 10, 0)
		}
		
		local Tween = TweenService:Create(Current, TWInfo, Goal)
		Tween:Play()
	end
end

Heres an example of using coroutine.wrap, this is my script for animating rocket thrusters

local ts = game:GetService("TweenService")
local ta = TweenInfo.new(.8,Enum.EasingStyle.Linear)
while true do
for _, v in ipairs(script.Parent:GetChildren()) do
	if v:IsA("MeshPart") then
		local co = coroutine.wrap(function()
			local t = ts:Create(v,ta,{Transparency = 1})
			t:Play()
			t.Completed:Wait()
			local t2 = ts:Create(v,ta,{Transparency = 0})
			t2:Play()
			t2.Completed:Wait()
		end)
		co()
	end
	end
end

to be honest my bad for the first reply as its completely wrong by guessing but here’s your fix so the coroutine must start when you for loop iterating through the parts in your Gaster Blaster

for i,v in pairs(script.Parent:GetChildren()) do
		
		if v:IsA("BasePart")or v:IsA('UnionOperation') then
			local co = coroutine.wrap(function()
			local tweenService = game:GetService("TweenService");
			
			local tweenInfo = TweenInfo.new(
				game:GetService("Players").RespawnTime - 0,
				Enum.EasingStyle.Quad,
				Enum.EasingDirection.Out
			)
			
			local goal = {
				Transparency = 0;
			}
			
			local finalTween = tweenService:Create(v, tweenInfo, goal)
		finalTween:Play()
          end)
co()
