Why is he shooting more balls in a loop every time his hp changes instead of 1 ball in a loop?

so i made this script that shoots fire balls but every time his hp changes he shoots an extra ball in a loop instead of just one. can somebody pls help me

function gang()
wait(.05)
local hp = script.Parent.Parent.fire.Health
if hp <29999 then
while true do -- adds ball each time his hp changes idk why pls help me fix this part	 
local bomb = game:GetService("ServerStorage").bomb
wait(.001)
  local throw = bomb:Clone()
throw.Position = script.Parent.Parent.UpperTorso.Position
throw.Parent = game.Workspace
throw.Anchored = true
wait(.001)
throw.Anchored = false
throw.Velocity = Vector3.new(0,-10,0)
local b = Instance.new("BodyVelocity")
b.Parent = throw
b.Velocity = script.Parent.Parent.LowerTorso.CFrame.LookVector * 120
b.MaxForce = Vector3.new(10000,10000,10000)
b.P = 1
wait(3)
throw:Destroy()
end
end
end
script.Parent.Parent.fire.HealthChanged:Connect(gang)

You are using a "while true do" loop which is making your boss(?) loop his ball shootout attack.

You don't actually need the "while true do", you can simply do this:

function gang()
    wait(.05)
    local hp = script.Parent.Parent.fire.Health
    if hp <29999 then
        local bomb = game:GetService("ServerStorage").bomb
        wait(.001)
        local throw = bomb:Clone()
        throw.Position = script.Parent.Parent.UpperTorso.Position
        throw.Parent = game.Workspace
        throw.Anchored = true
        wait(.001)
        throw.Anchored = false
        throw.Velocity = Vector3.new(0,-10,0)
        local b = Instance.new("BodyVelocity")
        b.Parent = throw
        b.Velocity = script.Parent.Parent.LowerTorso.CFrame.LookVector * 120
        b.MaxForce = Vector3.new(10000,10000,10000)
        b.P = 1
        wait(3)
        throw:Destroy()
    end
end
script.Parent.Parent.fire.HealthChanged:Connect(gang)
