Important function: AllocReplica() - must be overridden to create an object given an identifier for that object, which you define for all objects in your game
List of enumerations for how to get the list of valid objects for other systems.
| QUERY_REPLICA_FOR_CONSTRUCTION | For every object that does not exist on the remote system, call Replica3::QueryConstruction() every tick. Do not call Replica3::QueryDestruction() Do not call Connection_RM3::QueryReplicaList() |
| QUERY_REPLICA_FOR_CONSTRUCTION_AND_DESTRUCTION | For every object that does not exist on the remote system, call Replica3::QueryConstruction() every tick. Based on the call, the object may be sent to the other system. For every object that does exist on the remote system, call Replica3::QueryDestruction() every tick. Based on the call, the object may be deleted on the other system. Do not call Connection_RM3::QueryReplicaList() |
| QUERY_CONNECTION_FOR_REPLICA_LIST | Do not call Replica3::QueryConstruction() or Replica3::QueryDestruction() Call Connection_RM3::QueryReplicaList() to determine which objects exist on remote systems This can be faster than QUERY_REPLICA_FOR_CONSTRUCTION and QUERY_REPLICA_FOR_CONSTRUCTION_AND_DESTRUCTION for large worlds See GridSectorizer.h under /Source for code that can help with this |
| virtual Replica3* RakNet::Connection_RM3::AllocReplica | ( | RakNet::BitStream * | allocationIdBitstream, | |
| ReplicaManager3 * | replicaManager3 | |||
| ) | [pure virtual] |
Class factory to create a Replica3 instance, given a user-defined identifier.
Identifier is returned by Replica3::WriteAllocationID() for what type of class to create.
This is called when you download a replica from another system.
See Replica3::Dealloc for the corresponding destruction message.
Return 0 if unable to create the intended object. Note, in that case the other system will still think we have the object and will try to serialize object updates to us. Generally, you should not send objects the other system cannot create.
| [in] | allocationIdBitstream | user-defined bitstream uniquely identifying a game object type |
| [in] | replicaManager3 | Instance of ReplicaManager3 that controls this connection |
| virtual void RakNet::Connection_RM3::DeserializeOnDownloadComplete | ( | RakNet::BitStream * | bitStream | ) | [inline, virtual] |
Receives whatever was written in DeserializeOnDownloadComplete()
| [in] | bitStream | Written in SerializeOnDownloadComplete() |
| virtual void RakNet::Connection_RM3::DeserializeOnDownloadStarted | ( | RakNet::BitStream * | bitStream | ) | [inline, virtual] |
Receives whatever was written in SerializeOnDownloadStarted()
| [in] | bitStream | Written in SerializeOnDownloadStarted() |
| virtual void RakNet::Connection_RM3::GetConstructedReplicas | ( | DataStructures::List< Replica3 * > & | objectsTheyDoHave | ) | [virtual] |
Get list of all replicas that are constructed for this connection.
| [out] | objectsTheyDoHave | Destination list. Returned in sorted ascending order, sorted on the value of the Replica3 pointer. |
| RakNetGUID RakNet::Connection_RM3::GetRakNetGUID | ( | void | ) | const [inline] |
| SystemAddress RakNet::Connection_RM3::GetSystemAddress | ( | void | ) | const [inline] |
| bool RakNet::Connection_RM3::HasReplicaConstructed | ( | RakNet::Replica3 * | replica | ) |
Returns true if we think this remote connection has this replica constructed
| [in] | replica3 | Which replica we are querying |
| virtual ConstructionMode RakNet::Connection_RM3::QueryConstructionMode | ( | void | ) | const [inline, virtual] |
Queries how to get the list of objects that exist on remote systems.
The default of calling QueryConstruction for every known object is easy to use, but not efficient, especially for large worlds where many objects are outside of the player's circle of influence.
QueryDestruction is also not necessarily useful or efficient, as object destruction tends to happen in known cases, and can be accomplished by calling Replica3::BroadcastDestruction() QueryConstructionMode() allows you to specify more efficient algorithms than the default when overriden.
| virtual bool RakNet::Connection_RM3::QueryGroupDownloadMessages | ( | void | ) | const [inline, virtual] |
Return whether or not downloads to our system should all be processed the same tick (call to RakPeer::Receive() ).
Normally the system will send ID_REPLICA_MANAGER_DOWNLOAD_STARTED, ID_REPLICA_MANAGER_CONSTRUCTION for all downloaded objects, ID_REPLICA_MANAGER_SERIALIZE for each downloaded object, and lastly ID_REPLICA_MANAGER_DOWNLOAD_COMPLETE. This enables the application to show a downloading splash screen on ID_REPLICA_MANAGER_DOWNLOAD_STARTED, a progress bar, and to close the splash screen and activate all objects on ID_REPLICA_MANAGER_DOWNLOAD_COMPLETE However, if the application was not set up for this then it would result in incomplete objects spread out over time, and cause problems If you return true from QueryGroupDownloadMessages(), then these messages will be returned all in one tick, returned only when the download is complete
ID_REPLICA_MANAGER_DOWNLOAD_COMPLETE calls the callback DeserializeOnDownloadComplete()
| virtual void RakNet::Connection_RM3::QueryReplicaList | ( | DataStructures::List< Replica3 * > | newReplicasToCreate, | |
| DataStructures::List< Replica3 * > | existingReplicasToDestroy | |||
| ) | [inline, virtual] |
Callback used when QueryConstructionMode() returns QUERY_CONNECTION_FOR_REPLICA_LIST.
This advantage of this callback is if that there are many objects that a particular connection does not have, then we do not have to iterate through those objects calling QueryConstruction() for each of them.
BR> The following code uses a sorted merge sort to quickly find new and deleted objects, given a list of objects we know should exist.
BR> DataStructures::List<Replica3*> objectsTheyShouldHave; // You have to fill in this list
DataStructures::List<Replica3*> objectsTheyCurrentlyHave,objectsTheyStillHave,existingReplicasToDestro,newReplicasToCreatey;
GetConstructedReplicas(objectsTheyCurrentlyHave);
DataStructures::Multilist::FindIntersection(objectsTheyCurrentlyHave, objectsTheyShouldHave, objectsTheyStillHave, existingReplicasToDestroy, newReplicasToCreate);
BR> See GridSectorizer in the Source directory as a method to find all objects within a certain radius in a fast way.

| [out] | newReplicasToCreate | Anything in this list will be created on the remote system |
| [out] | existingReplicasToDestroy | Anything in this list will be destroyed on the remote system |
| virtual void RakNet::Connection_RM3::SerializeOnDownloadComplete | ( | RakNet::BitStream * | bitStream | ) | [inline, virtual] |
When a new connection connects, after constructing and serialization all objects, SerializeOnDownloadComplete() is called
| [out] | bitStream | Passed to DeserializeOnDownloadComplete() |
| virtual void RakNet::Connection_RM3::SerializeOnDownloadStarted | ( | RakNet::BitStream * | bitStream | ) | [inline, virtual] |
When a new connection connects, before sending any objects, SerializeOnDownloadStarted() is called
| [out] | bitStream | Passed to DeserializeOnDownloadStarted() |
