Problem with collision in a blood system. [ ? ]

So, I was making a blood system inspired by Blood Flow, and it works fine. But, it have a problem: It's not detecting collisions. What it should be: When the meatball fly off your body and something touchs it, a blood splat appears in the same positions has the meatball, but it isn't detecting collision. If I turn CanCollide true, it don't detect collision, if I put CanCollide false, it don't detect collision too. People said to I use Raycasting, but I don't know how could I do that. Here's my code:

--//Players\\--


local Players = game:GetService('Players')


--//Workspace\\--


local BloodParts = game:GetService('Workspace').BloodParts


--//ReplicatedStorage\\--


local ReS = game:GetService('ReplicatedStorage')


local BloodMeshes = ReS.BloodMeshes


--//RunService\\--


local RuS = game:GetService('RunService')


--//TweenService\\--


local TS = game:GetService('TweenService')


--//Delay and Others\\--


Debounce = false


--//Scripting\\--


Players.PlayerAdded:Connect(function(Player)


	Player.CharacterAdded:Connect(function(Character)


		local Humanoid = Character.Humanoid


		local OldHealth = Humanoid.Health


		Humanoid.HealthChanged:Connect(function(NewHealth)


			local HealthDifference = OldHealth - NewHealth


			OldHealth = NewHealth


			if HealthDifference <= 0 then


				return


			end


			local NumberOfDrops = math.floor(HealthDifference)


			if Debounce == false then


				Debounce = true


				for i = 0, NumberOfDrops do


					local MeatBall = BloodMeshes.MeatBall01:Clone()


					MeatBall.Position = Player.Character.Humanoid.RootPart.Position + Vector3.new(0, 2, 0)


					local BodyVelocity = Instance.new('BodyVelocity', MeatBall)


					BodyVelocity.MaxForce = Vector3.new(1000000000, 1000000000, 1000000000)

					BodyVelocity.P = Player.Character.Humanoid.RootPart.Position + Vector3.new(0, 2, 0)

					BodyVelocity.Velocity = Vector3.new(math.random(-10, 10), math.random(3, 6), math.random(-10, 10))


					local function RemoveBodyVelocity()


						wait(math.random(0.2, 0.3))


						BodyVelocity:Destroy()


					end


					MeatBall.Anchored = false

					MeatBall.Parent = BloodParts


					MeatBall.BloodLaunch:Play()


					RemoveBodyVelocity()


					local Touch


					function Touch()
						
						
						RuS.Heartbeat:Connect(function()
							
							
							MeatBall.Touched:Connect(function(Hit)


								if not Hit.Parent:FindFirstChildWhichIsA('Humanoid') then


									if not Hit.Name == 'Blood01' then


										if not Hit.Parent.Name == 'BloodParts' then


											if not Hit.Name == 'HumanoidRootPart' then


												if Debounce == true then


													Debounce = false


													MeatBall.Anchored = true

													MeatBall.Transparency = 1

													local SizeTween01 = TS:Create(BloodSplat, TweenInfo.new(0.5, Enum.EasingStyle.Cubic, Enum.EasingDirection.InOut, 0, false, 0), {Size = Vector3.new(BloodDropSize, 0.05, BloodDropSize)})

													local TransparencyTween01 = TS:Create(BloodSplat, TweenInfo.new(0.5, Enum.EasingStyle.Cubic, Enum.EasingDirection.InOut, 0, false, 0), {Transparency = 1})


													local PositionX = MeatBall.Position.X  +  math.random(-1, 2)  /  10

													local PositionY = MeatBall.Position.Y

													local PositionZ = MeatBall.Position.Z  +  math.random(-1, 2)  /  10


													BloodSplat.Position = Vector3.new(PositionX, PositionY, PositionZ)

													BloodSplat.Parent = BloodParts


													SizeTween01:Play()


													game:GetService('Debris'):AddItem(BloodSplat, 15)


													SizeTween01.Completed:Wait()

	end)

Could you use GetTouchingParts?
