I'm trying to figure out a few things about a gun turret. Can someone help me?

I'm making a gun turret to practice my raycasting abilities, and I am following a tutorial, but I have a problem. A few, actually. First, and biggest, in the findTarget function the script generates a ray, and multiplies it by 500 with a .Unit . What does that do? Second, I want to use that ray to make sure that its not firing at a wall the humanoid is hiding behind, but instead, the humanoid itself. Third, how would I add inaccuracy to my gun? Fourth, the FireBullet() function works, but how do I make the sound sound like its overlapping, it doesn't sound right, its sounds glitchy. Heres the code:

01gun = script.Parent
02 
03function FindTarget()
04    local dist = 100
05    local target = nil
06    for i,v in pairs(workspace:GetChildren()) do
07        local torso = v:FindFirstChild("Torso")
08        local humanoid = v:FindFirstChild("Humanoid")
09        if torso and humanoid and humanoid.Health > 0 then
10            if (gun.Position - torso.Position).magnitude < dist then
11                local ray = Ray.new(gun.Position, (gun.Position- torso.Position).Unit*500)
12                local hit,position = workspace:FindPartOnRayWithIgnoreList(ray,{torso.Parent})
13                if hit == nil then
14                    dist = (gun.Position - torso.Position).magnitude
15                    target = torso
16                else
17                    print(hit.Name)
18                end
19                dist = (gun.Position - torso.Position)
20                target = torso
21            end
22        end
23    end
24    return target
25end
26 
27function FireBullet()
28    s = workspace.Sound:Clone()
29    s.Parent = script.Parent
30    s:Play()
31    wait(0.6)
32    s:Destroy()
33end
34 
35while wait(0.3) do
36    local torso = FindTarget()
37    if torso then
38        gun.CFrame = CFrame.new(gun.Position, torso.Position)
39        local b = Instance.new("Part",workspace)
40        b.Size = Vector3.new(0.2,0.2,1)
41        b.BrickColor = BrickColor.new("New Yeller")
42        b.Velocity = gun.CFrame.lookVector*500
43        b.CFrame = gun.CFrame + Vector3.new(0.2,0.2,0.2)
44        b.Touched:connect(function(obj)
45        FireBullet()
46            local human =  obj.Parent:FindFirstChild("Humanoid")
47            if human then
48                human:TakeDamage(5)
49            end
50            if obj ~= gun then
51                game:GetService("Debris"):AddItem(b,0)
52            end
53        end)
54    end
55end

I believe your problem is..

.~~~~~~~~~~~~~~~~~ for i,v in pairs(workspace:GetChildren()) do

1I believe its this because not everything in the workspace may have a child 'Humanoid' which will trigger an error that will discontinue the code.

3You can use a pcall function or make it simple... But it will only work on Players

1for i, v in pairs(game.Players:GetPlayers()) do
2    wait()
3 
4    local Character = v.Character
5end

`1`	`Another reason it may be breaking when player character code runs the player isn't fully loaded...`

1for i,v in pairs(workspace:GetChildren()) do
2    wait()
3    --Code
4end

~~~~~~~~~~~~~~~~~

The gun itself works, the bullets fire at me and will hurt me, but I don't know how to make it stop firing when it stops seeing me (IE, go behind a wall) marfit 104 — 6y
