My Fireball will not work and goes anchored at random times?

I shoot my FireBall with Q and it goes foward and it's fine but when I spam it, it gets anchored but when it gets unanchored it sometimes doesn't do it and it is stuck on a line or something..

I am using "Play" not "Run" in studio I am using a LocalScript and a Script that is the damage inside the LocalScript I want my script to be able to be charged by holding Q and when released, gets shot foward

Of course, here is the script-

wait(0.5) Player = game.Players.LocalPlayer Mouse = Player:GetMouse() Character = Player.Character Enabled = true ButtonDown = true

local UserInputService = game:GetService("UserInputService") game:GetService("UserInputService").InputBegan:connect(function(input,gameprocesed)

if input.KeyCode == Enum.KeyCode.Q then
    if Enabled == false then return end 

Enabled = false 

BV = Instance.new("BodyVelocity")

 x = Instance.new("Part") 

 a = Instance.new("ParticleEmitter")

BP = Instance.new("BodyPosition", Character.HumanoidRootPart)

BG = Instance.new("BodyGyro", Character.HumanoidRootPart)


S = script["Damage"]:clone()

S.Parent = x
S.Disabled = true
x.CFrame = Character.HumanoidRootPart.CFrame*CFrame.new(0,0,0)


local Pos = Mouse.Hit.p

BG.D = 100

BG.maxTorque = Vector3.new(math.huge, math.huge, math.huge)

BG.cframe = CFrame.new(Player.Character.HumanoidRootPart.Position, Pos)

BP.Position = Player.Character.HumanoidRootPart.Position

BP.maxForce = Vector3.new(math.huge, math.huge, math.huge)

local Color1 = Color3.new(1,0,0)
local Color2 = Color3.new(1,1,0)
local keypoints = {}

x.Shape = "Ball"

x.Material = "SmoothPlastic"

x.Parent = Character

x.Transparency = 1

x.CanCollide = false

x.Orientation = Vector3.new(-90, 0, 0)
a.Parent = x

BV.maxForce = Vector3.new(math.huge, math.huge, math.huge)

BV.velocity = Character.HumanoidRootPart.CFrame.lookVector*100

BV.Parent = x

a.Color = ColorSequence.new(Color1,Color2,Color1)

a.LightEmission = 1

a.LightInfluence = 1

table.insert(keypoints, NumberSequenceKeypoint.new(0, 6.94, 0))

table.insert(keypoints, NumberSequenceKeypoint.new(0.422, 2.19, 0))

table.insert(keypoints, NumberSequenceKeypoint.new(1, 0, 0))

local multiValueSequence = NumberSequence.new(keypoints)

a.Size = multiValueSequence

a.Rate = 1000

a.Rotation = NumberRange.new(1000)

a.RotSpeed = NumberRange.new(1000)

a.Speed = NumberRange.new(10)

a.EmissionDirection = "Bottom"

a.Lifetime = NumberRange.new(1)

a.Texture = "rbxassetid://341300088"

x.Anchored = true

UserInputService = game:GetService("UserInputService")

UserInputService.InputEnded:Connect(function(input)

if ButtonDown == true then

if input.KeyCode == Enum.KeyCode.Q then 

    ButtonDown = false

    S.Disabled = false

    x.CFrame = Character.HumanoidRootPart.CFrame*CFrame.new(0,0,-3)

    x.Anchored = false


    BP:Destroy()        
BG:Destroy()

end

while ButtonDown == false do wait(5)

Enabled = true


x:Destroy() 
ButtonDown = true

end

end end) end

end)
