How to edit my gun gun script in order to make it won't kill my teammates?

I guess this should work :

local function createBullet(target) 
local bullet = tool.Bullet:Clone()
table.insert(ignoreTable, bullet)
bullet.Parent = workspace
bullet.CFrame = CFrame.new(muzzle.CFrame.p, target)
bullet.Trail.Enabled = true
wait() -- so trail has time to load

bullet.Transparency = 0
local missionAccomplished = false   

for i = 1, numSegments do
    if not missionAccomplished then
        local equation  = bullet.CFrame * CFrame.new(0, 0, -segmentLength) * CFrame.Angles(dropAngle, 0, 0)
        local ray = Ray.new(bullet.Position, (equation.p - bullet.Position).unit * segmentLength)
        local part, pos, normal, material = workspace:FindPartOnRayWithIgnoreList(ray, ignoreTable)
        if part and part.Parent:FindFirstChild("Humanoid") then
            missionAccomplished = true
            bullet.HitSound:Play()
            hitEvent:FireClient(game.Players:GetPlayerFromCharacter(tool.Parent))
            local hum = part.Parent.Humanoid

local plr = game.Players:GetPlayerFromCharacter(tool.Parent)
local HitPlayer = game.Players:GetPlayerFromCharacter(part.Parent) --the Character of the hit player

if HitPlayer.Team ~= plr.Team then

            if part.Name == "Head" and configs.headshotInstakill == true then
                local neck = part.Parent:FindFirstChild("Neck", true)
                neck:Destroy()


            elseif  part.Name == "Head" then
                hum:TakeDamage(headDamage)
            elseif part.Name == "Torso" or part.Name == "UpperTorso" or part.Name == "LowerTorso" then -- Names to account for R6 and R15
                hum:TakeDamage(torsoDamage)
            else
                hum:TakeDamage(otherDamage)
            end
end


            bullet.CFrame = CFrame.new(pos, equation.p)
            local weld = Instance.new("Weld", bullet)
            weld.C0 = bullet.CFrame:inverse() * part.CFrame
            weld.Part0 = bullet
            weld.Part1 = part
            bullet.Anchored = false
            --bullet.Trail.Enabled = false
            bullet.Transparency = 1
            if configs.blood == true then
                bullet.EffectAttachment.BloodEmitter:Emit(20)
            end
            wait(1)
            for ii, v in pairs(ignoreTable) do
                if v == bullet then
                    table.remove(ignoreTable, ii)
                end
            end
            bullet:Destroy()
        elseif part then

            bullet.ThudSound:Play()
            if hitParticles and part.Transparency and part.Transparency < 1 then
                if part.ClassName ~= "Terrain" then
