so I'm trying to create a bullet trail for a gun I'm making, this is what ive got so far(not do with the a trail)

local targetPoint = MyMouse.Hit.p
				local shootDirection = (targetPoint - Handle.Position).unit
				-- Adjust the shoot direction randomly off by a little bit to account for recoil
				shootDirection = CFrame.Angles((0.5 - math.random()) * 2 * Spread,
																(0.5 - math.random()) * 2 * Spread,
																(0.5 - math.random()) * 2 * Spread) * shootDirection
				local hitObject, bulletPos = RayCast(Handle.Position, shootDirection, Range)
				local bullet
				local bulletrail
				-- Create a bullet here
if hitObject then
bullet = CreateBullet(bulletPos) -- creates a bullet hole in the desired point
bulletrail = bullettrail(shootDirection,bulletPos,targetPoint) -- create bullet trail, what parameters would I need? 
end

-- the bullettrail function
local function bullettrail (shootDirection,bulletPos,targetPoint)
	Instance.new("Part",workspace)
	local P = Instance.new("Part") 
	P.Name = "BulletTrail" 
	local Place0 = script.Parent.Parent["Right Arm"].CFrame 
	P.formFactor = 0 
	P.Size = Vector3.new(1,1,(Place0 - shootDirection).magnitude) 
	P.CFrame = CFrame.new((Place0 + shootDirection)/2,Place0) 
	P.Parent = script.Parent.Parent
	P.BrickColor = BrickColor.Yellow()
	P.Anchored = true 
	P.CanCollide = false
	local m = Instance.new("BlockMesh")
	m.Scale = Vector3.new(0.1,0.1,1)
	m.Parent = P
end

so I'm just playing around with it and I'm sure sure I quiet understand raycasting and stuff enough to create a bullet trail, I have looked at the wiki - {magnitudes, and creating rays} but certain things I didn't understand, so if someone would help explain, that would be amazing, thanks a lot! :) ~Bubs
