How to Use Sounds and Particle Effects to Highlight Game Events

Resources Community Tutorials
#1

I have an Egg Hunt game that I’ve been working on and along the way I’ve really loaded up on the special effects attached to each egg, from bird chirping sounds that get louder as you get closer to the hidden egg, to confetti particle effects when you find the egg, to applause when you collect the egg. I even trigger a couple of custom events. I figured this might be of interest as a tutorial example so I added a bunch of comments and am showing the code below. This is a LocalScript named EggManager that I put into StarterPlayerScripts:

local CollectionService = game:GetService("CollectionService")
local ReplicatedFirst = game:GetService("ReplicatedFirst")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ServerStorage = game:GetService("ServerStorage")
local SoundService = game:GetService("SoundService")

local EggCollectedEvent = ReplicatedStorage:WaitForChild("EggCollectedEvent")
local FoundEggsListEvent = ReplicatedFirst:WaitForChild("FoundEggsListEvent")

local applauseSound = Instance.new("Sound")
applauseSound.SoundId = "rbxassetid://1869741275" -- Applause.
applauseSound.Volume = 5

local function getExplosion()
	local explosion = Instance.new("ParticleEmitter")
	explosion.Enabled = false
	explosion.Texture = "rbxassetid://6101261905" -- Sort of looks like confetti.
	explosion.Drag = 10
	explosion.Lifetime = NumberRange.new(0.2, 0.6)
	explosion.Speed = NumberRange.new(20, 40)
	explosion.SpreadAngle = Vector2.new(180, 180)
	return explosion
end

local function getNatureSound()
	local natureSound = Instance.new("Sound")
	natureSound.Looped = true
	-- Drop off quickly so the player knows when they are close to an egg and when they are not.
	natureSound.RollOffMaxDistance = 20
	natureSound.SoundId = "rbxassetid://169736440" -- ForestAmbienceVar2 (birds chirping, etc.)
	natureSound.Volume = 3
	return natureSound
end

for _, item in ipairs(workspace.HiddenEggs:GetChildren()) do
	local attachment = Instance.new("Attachment")
	local egg
	local gem
	local hasGem = item:FindFirstChild("Gem")
	if hasGem then
		-- item is a model containing an Egg and a Gem.
		egg = item.Egg
		gem = item.Gem
		CollectionService:AddTag(gem, "Gem") -- Tagged for the minimap.
	else
		-- item is an Egg with no Gem.
		egg = item
	end
	local explosion = getExplosion()
	local natureSound = getNatureSound()
	local prompt = Instance.new("ProximityPrompt")
	-- Diplay the prompt 5 studs above the egg to be more clearly visible.
	attachment.Position = Vector3.new(0, 5, 0)
	attachment.Parent = egg
	egg.Anchored = true
	-- Assign a random color to the egg so it is different each time the game is played.
	egg.BrickColor = BrickColor.random()
	explosion.Parent = egg
	natureSound.Parent = egg
	natureSound:Play() -- Birds chirping, etc.
	prompt.ActionText = "Collect Egg"
	-- Default is 10, but we want the player to be closer to the egg than that.
	prompt.MaxActivationDistance = 5
	-- Include the randomly assigned egg color to the text displayed in the proximity prompt.
	prompt.ObjectText = tostring(egg.BrickColor) .. " egg"
	prompt.Parent = attachment
	prompt.Triggered:Connect(function(player)
		explosion:Emit(300) -- Lots of "confetti" (sort of).
		local position = egg.Position + Vector3.new(0, 4, 0)
		-- Assign points and other server-side activity when an egg is collected.
		EggCollectedEvent:FireServer(position)
		-- Keep track of found eggs for a UI list.
		FoundEggsListEvent:Fire(egg)
		egg.Transparency = 1
		if hasGem then
			gem.Material = Enum.Material.Plastic
			-- Untagged so the gem is removed from the minimap.
			CollectionService:RemoveTag(gem, "Gem")
		end
		-- Move the egg from the HiddenEggs folder to the FoundEggs folder.
		item.Parent = workspace.FoundEggs
		natureSound:Stop()
		prompt.Enabled = false
		applauseSound.Parent = egg
		applauseSound:Play()
		applauseSound.Parent = SoundService
	end)
end
