TeamChangedEvent
constTeamChangedEvent:EventHandle<TeamChangedRecord,Reliable,Entity>
A player’s team changed, on her player entity, at the end of the
tick’s rules, whichever plugin answers the team question: her join’s
first team, her switch, a game’s setTeam or a balance. A change and
its reversal within one tick are no change. Read the cause, so a
player’s own switch and a game’s move are told apart.
