Auto firing system having trouble detecting characters?

I have a strange problem with my auto firing gun. For some reason, when a player walks into range it will fire off five or so shots, then stop. I am really confused especially because the gun will at times work perfectly.
I know this script looks really long but I basically just create a huge bubble around the gun and when it touches a player it will send a signal to start firing. (most of the actual bullet script is in another script/scripts and that all works fine, just the detection system seem to be malfunctioning sometimes). Here is the script:

ready = true
CF = script.Parent.Parent.X.CFrame
Target = workspace.Part
D = false
C = Instance.new("Part")
C.Shape = ("Ball")
C.Name = ("C")
X = 0
C.Size = Vector3.new(400,400,400)
C.Anchored = true
repeat wait (3) Vehical =   script.Parent.Parent.Parent.Parent:FindFirstChild("TeamName")   until Vehical ~= nil

print ("Joined  "..script.Parent.Parent.Parent.Parent:WaitForChild  ("TeamName").Value)

C.CanCollide = false

C.Transparency = 1

ReloadTime = 1

C.Parent = workspace







C.Touched:Connect(function(hit)



if hit.Name == ("Head") and game.Players:GetPlayerFromCharacter(hit.Parent).Team.Name ~= Vehical.Value and script.Parent.Parent.HP.Value > 0 then

print ("Target Aquired:"..(game.Players:GetPlayerFromCharacter(hit.Parent)).Team.Name.. "Entity Detected:Protect".. (Vehical.Value))

X = X + 1

local B = X

print("FIGHTING")

D = true

Target = hit

wait (5) if X == B then

D = false

end

end

if script.Parent.Parent.HP.Value < 0 then

Target = script.Parent.Parent.Gun

end

end)

while wait (ReloadTime) do

if script.Parent.Parent.HP.Value < 0 then

script.Parent.Parent.X.CFrame = CF

end



C.Position = script.Parent.Parent.X.Position

if D and script.Parent.Parent.HP.Value > 0 then





if script.Parent:FindFirstChild("Mounted") and ready and D then

ready = false

Gun = script.Parent.Configurations

ReloadTime = Gun.ReloadTime.Value

blue = ((0-ReloadTime) * 100) + 255

Damage = Gun.Damage.Value

Speed = Gun.LazerSpeed.Value

mounted = Gun.Parent.Mounted.Value



end

local finish = Target.Position

local start = script.Parent.Parent.X

Vehical = script.Parent.Parent.Parent.Parent.TeamName

wait ()

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local NumberEvent1 = ReplicatedStorage:WaitForChild("CreateNumberEvent1")

local Bullet = workspace.ServersideBulletScript2.Bullet:Clone()

Bullet.Parent = workspace

Bullet.CFrame = start.CFrame

local Part = Bullet;

Part.CFrame = CFrame.new(Part.Position, finish)

Part = start

if mounted then

Part.CFrame = CFrame.new(Part.Position, finish)

script.Parent.Parent.X.CFrame = Bullet.CFrame

end

Bullet.Anchored = false

Bullet.Velocity=Bullet.CFrame.lookVector *100



Bullet.Kill.Disabled = false

Bullet.Damage.Value = script.Parent.Configurations.Damage.Value

Bullet.Clean.Disabled = false

Bullet.Vehical.Value = script.Parent.Parent

Bullet.Player.Value = nil

local ray = Ray.new(start.Position,(finish-start.Position)*30000)

local ignoreList = {Vehical,Bullet}

local undecided = true

while undecided do wait ()

undecided = false

print (ignoreList)

hit, position = workspace:FindPartOnRayWithIgnoreList(ray, ignoreList)

print(hit)

if hit and hit.Transparency ~= 1 and hit.Name ~= ("Bullet") then

elseif hit ~= nil then undecided = true

table.insert(ignoreList, hit)

end

end

Bullet.Target.Value = position

Bullet.laser.Playing = true



wait (ReloadTime)

ready = true

end

end

Any help would be much apreciated.
