timeuntilwin = 1200 
totaltime = 1200 

raidteamcolor = "Really blue" 
defendteamcolor = "Really red" 
h = Instance.new("Hint") 

function OnTouched(hit) 

    if hit.Parent:findFirstChild("Humanoid") ~= nil then 
        if game.Players:GetPlayerFromCharacter(hit.Parent).TeamColor == BrickColor.new(raidteamcolor) then 
                script.Parent.BrickColor = BrickColor.new(raidteamcolor) 
        end 

        if game.Players:GetPlayerFromCharacter(hit.Parent).TeamColor == BrickColor.new(defendteamcolor) then
                script.Parent.BrickColor = BrickColor.new(defendteamcolor) 
                timeuntilwin = totaltime  
                for i, v in pairs(game.Workspace:GetChildren()) do 
                    if v:IsA("Hint") then 
                            v:remove() 
                    end 
                end 
        end 

    end

                        h.Parent = game.Workspace 
                        h.Text = "Raiders win in".." "..timeuntilwin 

                        if timeuntilwin <= totaltime  and timeuntilwin > 0 then 
                        wait(1) 
                        timeuntilwin = timeuntilwin - 1
