Troubles With Tweening Particle Emitter

Hello!
I am attempting to advance the vfx in my wip tower defense game. Initially, when the towers attacked they would just use the default roblox fire as a trail and it worked fine.

-- ORIGINAL CODE
local function fireProjectile(tower, target)
	local projectile = Instance.new("Part")
	projectile.Size = Vector3.new(1,1,1)
	projectile.CFrame = tower.Head.CFrame
	projectile.Anchored = true
	projectile.CanCollide = false
	projectile.Transparency = 1
	projectile.Parent = workspace.Camera
	
	local fire = Instance.new("Fire")
	fire.Size = 2
	fire.Heat = 0.1
	fire.Color = tower.Config.Trail.Value
	fire.Parent = projectile

	local projectileTween = TweenService:Create(projectile, TweenInfo.new(0.3), {Position = target.HumanoidRootPart.Position})
	projectileTween:Play()
	Debris:AddItem(projectile, 0.3)
end

Then I decided that I wanted to upgrade the effects, my plan for this was to use a particle emitter instead of fire. But I can’t get it to move towards the mobs.


It just teleports towards them, this is the updated code:

--UPDATED CODE
local function fireProjectile(tower, target)
	local projectile = Instance.new("Part")
	local distance = (tower.Head.Position - target.HumanoidRootPart.Position).Magnitude
	projectile.Size = Vector3.new(1,1,1)
	projectile.CFrame = tower.Head.CFrame
	projectile.Anchored = true
	projectile.CanCollide = false
	projectile.Transparency = 1
	projectile.Parent = workspace.Camera

	local emitter = Instance.new("ParticleEmitter")
	emitter.Texture = "rbxassetid://12390113643"
	emitter.Size = NumberSequence.new(2)
	emitter.Squash = NumberSequence.new(-0.3)
	emitter.Rate = 5
	emitter.Speed = NumberRange.new(15, 30)
	emitter.LightEmission = 1 
	emitter.LightInfluence = 0
	emitter.Parent = projectile
	emitter.SpreadAngle = Vector2.new(-360, 360)
	emitter.FlipbookMode = Enum.ParticleFlipbookMode.OneShot
	emitter.FlipbookLayout = Enum.ParticleFlipbookLayout.Grid8x8
	emitter.Lifetime = NumberRange.new(1,1)


	local projectileTween = TweenService:Create(projectile, TweenInfo.new(0.3), {Position = target.HumanoidRootPart.Position})
	projectileTween:Play()
	Debris:AddItem(projectile, 0.31)
end

I’m not sure as to why it worked with the fire and not the particle emitter, my best guess is that it has something to do with the tween.

Specifically this line here

local projectileTween = TweenService:Create(projectile, TweenInfo.new(0.3), {Position = target.HumanoidRootPart.Position})

Any help is appreciated!

What exactly is tower? Aren’t you setting the particle’s CFrame to the enemie’s CFrame by any chance?

Tower is the model in the workspace

In the line of code you selected, that is supposed to be the starting point.

Its at the end of this line of code that it tells it to code to the mobs’s model
