C++ Battleground::GetStatus方法代码示例

/*
    this event has many possibilities when it is executed:
    1. player is in battleground (he clicked enter on invitation window)
    2. player left battleground queue and he isn't there any more
    3. player left battleground queue and he joined it again and IsInvitedToBGInstanceGUID = 0
    4. player left queue and he joined again and he has been invited to same battleground again -> we should not remove him from queue yet
    5. player is invited to bg and he didn't choose what to do and timer expired - only in this condition we should call queue::RemovePlayer
    we must remove player in the 5. case even if battleground object doesn't exist!
