Clearing and restarting collision group problem?

Right now I have a collision group script which sets players to be able to walk through their own team doors, without being able to walk through the opposing teams doors. I got most of this from the wiki. The problem I am facing however, is 1. It only sets the players collision group when their character respawns and 2. It carries over from round to round. I have a section where if the round is not in progress then I want to clear all collision group, but I want when a new round starts for the new collision groups to be setup according to each players team. Can anyone help me, because I cant't find anywhere how to remove players from a collision group on any of the wikis

If you investigate the SetPartCollisionGroup function, you can realize that all it does is configure each Part's CollisionGroupId. This means that any one part can only belong to a single CollisionGroup at any one time. Thus, to get a player out of a CollisionGroup, simply assign all their parts' CollisionGroupId to 0 or call SetPartCollisionGroup(part, "Default") (http://wiki.roblox.com/index.php?title=API:Class/PhysicsService/CreateCollisionGroup suggests that is the name reserved for group id 0).
I recommend this code for PlayerAdded:
function CollisionNameFromTeam(team)
return team.Name .. "Players"
end
function CharacterValid(char)
return char and char:FindFirstChild("Humanoid") and char.Humanoid.Health > 0
end
function SetProperCollisionGroup(p)
if p.Team and p.Team.Name ~= "Lobby" then
setCollisionGroupRecursive(p.Character, CollisionNameFromTeam(p.Team))
else
setCollisionGroupRecursive(p.Character, "Default")
end
end
game.Players.PlayerAdded:Connect(function(p)
p.CharacterAdded:Connect(function(char)
SetProperCollisionGroup(p)
end)
p:GetPropertyChangedSignal("Team"):Connect(function()
if not CharacterValid(p.Character) then return end
SetProperCollisionGroup(p)
end)
end)
Instead of waiting for the Team to become correct, it uses events to make sure that regardless of respawning/changing teams, the collision group will always be correct.
