I'm making a gun with RayCasting, but the Raycast can go through stuff, Help?

So, as the title says, I'm making a gun, and you can shoot through walls with certain camera angles. What I want to do is make the Raycast resize itself to not go through the wall. As You can see in the script, I already tried something, but it Didn't work. I don't know if I'm doing something wrong with RayCastParams, If I am, how do i solve it?

local Cooldown = false
local NonCollideDescendants = nil

local function MakeBullet(Start, End, Dist) 
	
	local Lazer = Instance.new("Part")
	Lazer.Parent = game.Workspace
	Lazer.Anchored = true
	Lazer.CanCollide = false
	Lazer.Size = Vector3.new(.1, .1, Dist)
	Lazer.CFrame = CFrame.new(Start, End) * CFrame.new(0, 0, - Dist / 2)
	Lazer.Name = "Lazer"
	
end

script.Parent.Event.OnServerEvent:Connect(function(player, FromP, ToP, Hum, Part)
	
	local PlayerStuff = nil
	
	for i, Descendants in pairs(game.Workspace:GetDescendants()) do

		if Descendants:IsA("Part") or Descendants:IsA("MeshPart") then
			
			if  Descendants.CanCollide == false then
				
				NonCollideDescendants = Descendants
				
			end

		end

	end
	
	for i, Descendantss in pairs(player.Character:GetDescendants()) do

		if Descendantss:IsA("Part") or Descendantss:IsA("MeshPart") then

			if  Descendantss.CanCollide == false then

				PlayerStuff = Descendantss

			end

		end

	end
	
	if Cooldown == false then
		
		Cooldown = true
		local Pos = ToP
		local CharacterParts = player.Character:GetDescendants()
		
		--local RayCast = Ray.new(script.Parent.Handle.Position, (ToP - FromP).unit * 100)
		local RayCast = (FromP - ToP).Unit * 100
		
		local Params = RaycastParams.new()
		Params.FilterType = Enum.RaycastFilterType.Blacklist
		Params.FilterDescendantsInstances = {

			PlayerStuff,
			NonCollideDescendants

		}
		
		--local Part, Position, Normal = game.Workspace:FindPartOnRay(RayCast , player.Character , false , true, RaycastParams)
		local RayCastResult = workspace:Raycast(FromP, RayCast, Params)
		local Dist = (ToP - FromP).magnitude
		
		if Dist > 100 then
			
			Dist = 100
			
		end

		local Sound = script.Parent.Sound
		Sound:Play()
		
		if Hum ~= nil then
			
			Hum:TakeDamage(50)
			
		end
		
		MakeBullet(FromP, ToP, Dist)
		
		wait(.28)
		Cooldown = false
			
	end
	
end)

Btw. Sorry For the messy script lol

Edit: I know what the problem is! But I still need help, It's using "ToP" as the part's end Position, and "ToP" is the Mouse Position, so what I need to do Is get the Raycast's end position.. But I don't know how :/
