// I<>m not sure if player spawn cache is the most descriptive name, but essentially
|
|||
|
|
// there is a singleton instance of CPlayerSpawnCache for the local player which has
|
|||
|
|
// a set of counters/pointers/etc. that get cleared every time a map loads. This
|
|||
|
|
// can be useful for situations where a player<65>s net connection chokes and they get
|
|||
|
|
// a full update, which recreates their C_TF_Player entirely or otherwise invalidates
|
|||
|
|
// a bunch of data in the local player. I believe it<69>s already known that there is
|
|||
|
|
// a class of bugs stemming from this behavior.
|
|||
|
|
//
|
|||
|
|
// Right now the cache is used as a way to display a message to the player if they
|
|||
|
|
// connect to a server that<61>s recording replays. As soon as they choose their player
|
|||
|
|
// class, a counter is checked, and if it<69>s zero the message is displayed. The counter
|
|||
|
|
// is then incremented. This is a sort of odd use for it actually. A better example
|
|||
|
|
// would be what I<>m going to do next, which is that if the player<65>s net connection
|
|||
|
|
// chokes (or if you host_timescale at too great a speed and cause a full update on the
|
|||
|
|
// client), the replay system will think that you<6F>ve already saved a replay for that life.
|
|||
|
|
// So this example will be a perfect time to use the player spawn cache because you can
|
|||
|
|
// maintain some level of persistence in the face of your entire local player getting
|
|||
|
|
// nuked.
|
|||
|
|
//
|
|||
|
|
// Just add any data members you'd like to access to the CPlayerSpawnCache::Data_t
|
|||
|
|
// struct and it will be cleared automatically (via a memset) whenever a new map is
|
|||
|
|
// loaded.
|
|||
|
|
//
|
|||
|
|
// It's possible that PreReset()/PostReset() or the like will be necessary for this
|
|||
|
|
// class to reach its full potential.
