Blood splatter script spawning a lot of splatters at 0, 0

[CloutBl0x (clout)]

Somehow everytime I take damage my blood splatter script not only spawns splatters around the player, but also spawns roughly 10 splatters at 0, 0.

Can someone explain why this is happening and how I can fix this?

Script:

local splatids = {"408754747","408320359","408320438","508050982" }

local char = script.Parent.Parent
local human = char:WaitForChild("Humanoid")

local splatFolder = workspace.DamageDebris.BloodSplatters

human.HealthChanged:Connect(function()
	
	local headcf = char.Head.CFrame
	
	for i = 1, 15 do
		
		local a = Instance.new("Part", nil)
		a.Parent = splatFolder
		a.Name = "BloodSplat"
		a.Size = Vector3.new(math.random(2,5),math.random(2,5),0.05)
		a.Transparency = 1
		a.CanCollide = false
		a.Anchored = true
			
		local decal1 = Instance.new("Decal", a)
		decal1.Name = "Blood1"
		decal1.Texture = "rbxassetid://"..splatids[math.random(1, 4)]
		
		local decal2 = Instance.new("Decal", a)
		decal1.Name = "Blood2"
		decal2.Texture = decal1.Texture or decal2.Parent.Blood1.Texture
		decal2.Face = "Back"
		
		local dir = Vector3.new(math.random(-50,50),math.random(-50,50),math.random(-50,50)).Unit * 20
		local ray = Ray.new(headcf.Position, dir)
		local part,pos,normal = workspace:FindPartOnRay(ray, char, false, true)
		
		if part ~= nil then
			a.CFrame = CFrame.new(pos,pos + normal)
			a.Parent = splatFolder
		end
		
		game:GetService("Debris"):AddItem(a, 30)
	end
end)

You’re spawning blood splatters before doing the raycast check. You should only be spawning them if the ray hits something (inside the if statement)
