How do I make this gun weapon script anti-teamkill? [closed]

pcall(function() if (hit.Parent:findFirstChild("Hit")) then hit.Parent.Health.Value = hit.Parent.Health.Value - damage end local numbd = 0 for i = 1,#suits do if hit.Parent.Name == suits[i] then numbd = numbd + 1 end end if (hit.Parent.className == "Hat") or (hit.Parent.className == "Tool")or (numbd>=1)  then if (hit.Name == "Riot Shield") then return end    if (game.Players:GetPlayerFromCharacter(hit.Parent.Parent)) then 
end end 
    if (hit.Parent ~= player.Character) then 
tagHumanoid(hit.Parent.Humanoid, player) if (hit.Name == "Head") then damagehum(damage*3, hit.Parent) elseif(hit.Name == "Head") then damagehum(damage*1.2, hit.Parent) else damagehum(damage, hit.Parent) end end end )
    game:service("Debris"):AddItem(p,0.075)
end
end

I need to make it so that the bullet only damages enemies and not people of the same team color.
