Why doesn't my ray change directions? (More info in desc)

Code:

for i = 1,3,1 do
	local ray = Ray.new(char.HumanoidRootPart.CFrame.p, mouse.p)
	local trident = game.ReplicatedStorage.Trident:Clone()
	trident.BrickColor = BrickColor.new("Bright blue")
	trident.Material = Enum.Material.Neon
	trident.CanCollide = false
	trident.CFrame = char.HumanoidRootPart.CFrame*CFrame.new(0,3,0)
	trident.CFrame = CFrame.new(trident.CFrame.p,mouse.p)*CFrame.Angles(0,math.rad(180),0)
	trident.Parent = char
	
	local BV = Instance.new("BodyVelocity")
	BV.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
	BV.Velocity = ray.Direction*1
	BV.Parent = trident
	wait(2)
end

FOR LOOPS. I've been trying to figure out the problem but I'm still just a beginner. In this code the trident should have different directions depending on where the mouse is pointed at, right? WELL NO! MY TRIDENTS HAVE DECIDED TO FOLLOW THE FIRST POSITION THEY WENT THROUGH. How do I fix this?

mouse.Hit.p not mouse.p
