/** The race manager has two functions:
|
|
* 1) it stores information about the race the user selected (e.g. number
|
|
* of karts, track, race mode etc.). Most of the values are just stored
|
|
* from the menus, and just read back, except for GP mode (the race
|
|
* manager stores the GP information, but World queries only track
|
|
* and number of laps, so in case of GP this information is taken from
|
|
* the GrandPrix object), and local player information (number of local
|
|
* players, and selected karts). The local player information is read
|
|
* from the NetworkManager, gathered on the server (from all clients and
|
|
* the server, see NetworkManager::setupPlayerKartInfo), and then the
|
|
* combined information distributed to all RaceManagers in all clients
|
|
* and server. Even in no networking mode, the data flow is the same:
|
|
* information about local players is stored here, then processed by
|
|
* NetworkManager::setupPlayerKartInfo and the 'global' information about
|
|
* player karts is set in the RaceManager, to be used by World later on.
|
|
* 2) when a race is started, it creates the world, and keeps track of
|
|
* score during the race. When a race is finished, it deletes the world,
|
|
* and (depending on race mode) starts the next race by creating a new
|
|
* world.
|
|
* Information in the RaceManager is considered to be 'more static', sometimes
|
|
* the world has similar functions showing the current state. E.g.: the
|
|
* race manager keeps track of the number of karts with which the race was
|
|
* started, while world keeps track of the number of karts currently in the
|
|
* race (consider a race mode like follow the leader where karts can get
|
|
* eliminated, but still the RaceManager has to accumulate points for those
|
|
* karts).
|
|
* The race manager handles all race types as a kind of grand prix. E.g.:
|
|
* a quick race is basically a GP with only one track (so the race manager
|
|
* keeps track of scores even though no scores are used in a quick race).
