Raycasting, "Attempt to call a table value"?

Good morning guys, i have this error, that is very very weird, just for the fact that i have did this before and this didnt even give me this error while raycasting other guns that i have coded. I have thought that the problem may be my “BodyAttach” part, that is just a part that cointains motor6ds and sounds for the gun, but when i dont put anything on the FilterDescendantsInstances() brackets, the error stills appearing. Here i leave my code, also this is a LocalScript

local WeaponTool = script.Parent.MP40

local function shoot()
    local now = tick()
    if now - lastFire >= shootDelay then
			lastFire = now
			
			
			local origin = WeaponTool.ShootPart.Position
			local destination = mouse.Hit.Position
			local direction = (destination - origin).Unit*700
			local raycastParams = RaycastParams.new()
			raycastParams.FilterDescendantsInstances(WeaponTool)
			raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
			local result = workspace:Raycast(origin, direction, raycastParams)
			local intersection = result and result.Position or origin + direction
			local distance = (origin - intersection).Magnitude
			onShootEvent:FireServer(distance, result, intersection, origin, lastFire, shootDelay)
		
			SoundEvent.OnClientEvent:Connect(function(plr, shootsound)
					shootsound:Play()
			end)
		
		
			Bullets.Value -= 1
			
		local shootAnimation = Instance.new("Animation")
		shootAnimation.AnimationId = "rbxassetid://5671559974"
		local shootAnimTrack = char:WaitForChild("Humanoid"):LoadAnimation(shootAnimation):Play()
		
		
    else
        --Let use know they have to wait, if you want too
    end
end

Output:

Thanks in advance!!!

FilterDescendantsInstances is a property that takes an array as it’s value, not a function. So you need to something like this:
raycastParams.FilterDescendantsInstances = {WeaponTool}

Ah yes, you are trying to call a table value that must not exist. That happens to me sometimes. Is there a value that does nothing you are trying to call?

Tell me what Line 62 is in your code please.

Pretty sure he is talking about the line with raycastParams.FilterDescendantsInstances(WeaponTool)

Ben’s line is correct, to call a table value for your code you use this:
raycastParams.FilterDescendantsInstances = {WeaponTool} You are setting it equal to the value.
Using this line under here will not work because you are not calling the table right.
raycastParams.FilterDescendantsInstances(WeaponTool) – This line is not right. Replace it with the one above here.

In under to call a table, you need to set it equal to the table.

Thanks BenMactavsin and jumbopushpop112!!! It was something very simple and basic, sorry!!! Thanks so much!!

No problem man! It’s ok. We all make mistakes on basic code. Trust me I have before. Mark one of the posts with the solution so that this topic is flagged as completed.
