[HELP!] How to emit particles by script

[HugeGodOfLighting (EcoDexter)]

1. I want to understand why my script is not working

2. I have this script I am trying to emit particles by script upon purchase of diamonds
   I have the script full of debugging and still the particles are not showing at all.
   Even though the script is working as intended based on the output.
   I know this might be to easy for a lot of you guys but I’m new to scripting and was looking for answers.

Help is appreciated!

Script :

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local player = Players.LocalPlayer
local diamondShopFrame = player.PlayerGui:WaitForChild("DiamondShop"):WaitForChild("DiamondShopFrame")
local shopScrollingFrame = diamondShopFrame:WaitForChild("ShopScrollingFrame")

-- Effects references
local effectsFolder = ReplicatedStorage:WaitForChild("Effects")
local diamondAttachmentTemplate = effectsFolder:WaitForChild("DiamondPurchase"):WaitForChild("DiamondAttachment")
local diamondFalling = diamondAttachmentTemplate:WaitForChild("DiamondFalling")
local fireworks = diamondAttachmentTemplate:WaitForChild("Fireworks")

local blingSound = diamondFalling:WaitForChild("Bling")
local launchSound = fireworks:WaitForChild("Launch")
local boomSound = fireworks:WaitForChild("Boom")

-- Developer product IDs
local productIds = {
	[2000] = 2689140779,  -- 100 Robux for 2000 Diamonds
	[5000] = 2689140778,  -- 250 Robux for 5000 Diamonds
	[15000] = 2689140776, -- 750 Robux for 15000 Diamonds
	[50000] = 2689140777, -- 1500 Robux for 50000 Diamonds
}

-- Function to handle button clicks inside the ShopScrollingFrame
local function onButtonClick(diamondAmount)
	local productId = productIds[diamondAmount]
	if productId then
		print("[DEBUG] Player clicked to purchase", diamondAmount, "diamonds with product ID:", productId)
		MarketplaceService:PromptProductPurchase(player, productId)
	else
		warn("[DEBUG] Invalid diamond amount or product ID for:", diamondAmount)
	end
end

-- Attach button click events to buttons inside ShopScrollingFrame
shopScrollingFrame:WaitForChild("2000Diamonds").MouseButton1Click:Connect(function()
	print("[DEBUG] 2000 Diamonds button clicked.")
	onButtonClick(2000)
end)
shopScrollingFrame:WaitForChild("5000Diamonds").MouseButton1Click:Connect(function()
	print("[DEBUG] 5000 Diamonds button clicked.")
	onButtonClick(5000)
end)
shopScrollingFrame:WaitForChild("15000Diamonds").MouseButton1Click:Connect(function()
	print("[DEBUG] 15000 Diamonds button clicked.")
	onButtonClick(15000)
end)
shopScrollingFrame:WaitForChild("50000Diamonds").MouseButton1Click:Connect(function()
	print("[DEBUG] 50000 Diamonds button clicked.")
	onButtonClick(50000)
end)

-- Function to play the particle effects as a purchase confirmation
local function playParticleEffects()
	print("[DEBUG] Starting particle effects.")

	local character = player.Character or player.CharacterAdded:Wait()
	local torso = character:FindFirstChild("Torso")
	if not torso then
		warn("[DEBUG] Torso not found for player:", player.Name)
		return
	end
	print("[DEBUG] Found Torso for player:", player.Name)

	-- Clone and attach the DiamondAttachment
	local diamondAttachmentClone = diamondAttachmentTemplate:Clone()
	diamondAttachmentClone.Parent = torso
	diamondAttachmentClone.Position = Vector3.new(0, 0, 0) -- Center it relative to torso
	print("[DEBUG] DiamondAttachment cloned and parented to Torso.")

	-- Emit particles
	print("[DEBUG] Attempting to emit DiamondFalling particles.")
	diamondFalling:Emit(10)
	print("[DEBUG] DiamondFalling particles emitted.")

	print("[DEBUG] Attempting to emit Fireworks particles.")
	fireworks:Emit(10)
	print("[DEBUG] Fireworks particles emitted.")

	-- Cleanup after effects
	task.delay(3, function()
		print("[DEBUG] Cleaning up DiamondAttachment.")
		diamondAttachmentClone:Destroy()
	end)
end

-- Function to handle purchase success
MarketplaceService.PromptProductPurchaseFinished:Connect(function(finishedUserId, productId, wasPurchased)
	print("[DEBUG] PromptProductPurchaseFinished triggered for User ID:", finishedUserId, "Product ID:", productId, "Was Purchased:", wasPurchased)

	local finishedPlayer = Players:GetPlayerByUserId(finishedUserId)
	if not finishedPlayer then
		warn("[DEBUG] Could not find player for User ID:", finishedUserId)
		return
	end

	if finishedPlayer == player and wasPurchased then
		print("[DEBUG] Purchase successful for product ID:", productId)

		-- Close the DiamondShopFrame
		diamondShopFrame.Visible = false
		print("[DEBUG] DiamondShopFrame closed.")

		-- Trigger particle effects as confirmation
		playParticleEffects()

		-- Add diamonds to the player's leaderstats
		local updateDiamonds = ReplicatedStorage.RemoteFunctions:WaitForChild("UpdateDiamonds")
		local success = updateDiamonds:InvokeServer(productId)
		if success then
			print("[DEBUG] Successfully updated diamonds on the server.")
		else
			warn("[DEBUG] Failed to update diamonds on the server.")
		end
	elseif not wasPurchased then
		print("[DEBUG] Purchase was canceled or failed.")
	end
end)

You never set the object for it to emit from but rather their original references, just change it where it emits to the object you cloned and parented in.

Try adding a MarketplaceService line at the top

local marketPlaceService = game:GetService("MarketplaceService")

or try for the torso line

local torso = character:FindFirstChild("Torso") or character:FindFirstChild("UpperTorso")
