Size of ParticleEmitter not being tweened

[Violet_sheer (TheOtherSider)]

I’m trying to tween the size of a particle emitter to create a nice VFX but i’m getting the error:

TweenService:Create property named 'Size' on object 'Power' is not a data type that can be tweened

I’m tweening a NumberSequence with keypoints inside and I asked the AI assistant if I could tween the size of a particle emitter or not and it said I could but the error messge says otherwise.

Code

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local RunService = game:GetService("RunService")
local TweenService = game:GetService("TweenService")

local Remotes = ReplicatedStorage.Remotes
local Assets = ReplicatedStorage.Assets
local Projectiles = Assets.Projectiles.Blackhole

local Blackhole = {}

function Blackhole:Init()
	Remotes.ToClient.OnClientEvent:Connect(function(signal,character,hitboxName)
		if signal == "Blackhole" then
			if character.Parent ~= workspace then return end
			local poop = workspace:FindFirstChild(hitboxName)
			local ap = Instance.new("AlignPosition")
			
			ap.Mode = Enum.PositionAlignmentMode.OneAttachment
			ap.Position = poop.Position
			ap.MaxVelocity = 1e6
			ap.MaxForce = 1e6
			ap.Responsiveness = 100
			ap.Attachment0 = character:FindFirstChild("HumanoidRootPart").RootAttachment
			ap.Parent = character.HumanoidRootPart
			
			task.spawn(function()
				while true do
					ap.Position = poop.Position
					task.wait()
					if poop.Parent ~= workspace then
						ap:Destroy()
						break
					end
				end
			end)
		elseif signal == "BlackholeFX" then
			local particles = Projectiles.Particles:GetChildren()
			local poop = workspace:FindFirstChild(character)
			local attachment = poop:FindFirstChild("Attachment")
			
			for i,v in particles do
				local new = v:Clone()
				new.Parent = attachment
			end

			attachment.Parent = poop
		end
	end)
	
	Remotes.ToClient.OnClientEvent:Connect(function(signal,partName)
		if signal == "Supernova" then
			local part = workspace:FindFirstChild(partName)
			local info = TweenInfo.new(0.5,Enum.EasingStyle.Exponential,Enum.EasingDirection.In)
			local supernova = Projectiles.Supernova:Clone()
			local particle = supernova.Attachment.Power
			local c1 = RunService.Heartbeat:Connect(function()
				supernova.Position = part.Position
			end)
			local c2
			local blackhole
			
			local size = NumberSequence.new({
				NumberSequenceKeypoint.new(0,3.5),
				NumberSequenceKeypoint.new(1,3.5),
			})
			TweenService:Create(particle,info,{Size = size}):Play()
			local supernovaIn = TweenService:Create(supernova,info,{Size = supernova.Size/2})
			supernovaIn:Play()
			
			supernovaIn.Completed:Connect(function()
				c1:Disconnect()
				supernova:Destroy()
				blackhole = Projectiles.Final:Clone()
				blackhole.Size /= 2
				blackhole.Parent = workspace
				
				c2 = RunService.Heartbeat:Connect(function()
					blackhole.Position = part.Position
				end)
				TweenService:Create(blackhole,info,{Size = blackhole.Size * 2}):Play()
				task.wait(1.5)
				blackhole:Destroy()
				c2:Disconnect()
			end)
		end
	end)
end

return Blackhole

In the bottom client event with the signal “Supernova” I am tweening a NumberSequence.

Unfortunately TweenService does not support tweening NumberSequence. You can look at the supported types, its actually the first thing that is presented.
TweenService | Documentation - Roblox Creator Hub

However, you can use this module (which does state it supports NumberSequence)
BoatTween module - Resources / Community Resources - Developer Forum | Roblox

Module doesn’t seem to work for me and the git documents don’t align with my functions. I’m getting the error attempt to index nil with Play. (tween:Play())

I’ll hang onto this module, thanks.
