Detailed Description
The
RPC3 plugin allows you to call remote functions as if they were local functions, using the standard function call syntax.
No serialization or deserialization is needed.
As of this writing, the system is not threadsafe.
Features:
Pointers to classes that derive from NetworkID are automatically looked up using NetworkIDManager Types are written to BitStream, meaning built-in serialization operations are performed, including endian swapping Types can customize autoserialization by providing an implementation of operator << and operator >> to and from BitStream
- Note:
- You cannot use RPC4Plugin at the same time as RPC3
Member Function Documentation
bool RakNet::RPC3::Call |
( |
const char * |
uniqueIdentifier |
) |
[inline] |
Calls a remote function, using as send parameters whatever was last passed to SetTimestamp(), SetSendParams(), SetRecipientAddress(), and SetRecipientObject() If you call a C++ class member function, don't forget to first call SetRecipientObject(). You can use CallExplicit() instead of Call() to force yourself not to forget.
Parameters passed to Call are processed as follows: 1. If the parameter is not a pointer 2. - And you overloaded RakNet::BitStream& operator<<(RakNet::BitStream& out, MyClass& in) then that will be used to do the serialization 3. - Otherwise, it will use bitStream.Write(myClass); BitStream already defines specializations for NetworkIDObject, SystemAddress, other BitStreams 4. If the parameter is a pointer 5. - And the pointer can be converted to NetworkIDObject, then it will write bitStream.Write(myClass->GetNetworkID()); To make it also dereference the pointer, use RakNet::_RPC3::Deref(myClass) 6. - And the pointer can not be converted to NetworkID, but it is a pointer to RakNet::RPC3, then it is skipped 7. Otherwise, the pointer is dereferenced and written as in step 2 and 3.
- Note:
- If you need endian swapping (Mac talking to PC for example), you pretty much need to define operator << and operator >> for all classes you want to serialize. Otherwise the member variables will not be endian swapped.
If the call fails on the remote system, you will get back ID_RPC_REMOTE_ERROR. packet->data[1] will contain one of the values of RPCErrorCodes. packet->data[2] and on will contain the name of the function.
- Parameters:
-
[in] | uniqueIdentifier | parameter of the same name passed to RegisterFunction() on the remote system |
bool RakNet::RPC3::CallExplicit |
( |
const char * |
uniqueIdentifier, |
|
|
const CallExplicitParameters *const |
callExplicitParameters | |
|
) |
| | [inline] |
Calls a remote function, using whatever was last passed to SetTimestamp(), SetSendParams(), SetRecipientAddress(), and SetRecipientObject() Passed parameter(s), if any, are serialized using operator << with RakNet::BitStream. If you provide an overload it will be used, otherwise the seriailzation is equivalent to memcpy except for native RakNet types (NetworkIDObject, SystemAddress, etc.) If the type is a pointer to a type deriving from NetworkIDObject, then only the NetworkID is sent, and the object looked up on the remote system. Otherwise, the pointer is dereferenced and the contents serialized as usual.
- Note:
- The this pointer, for this instance of RPC3, is pushed as the last parameter on the stack. See RPC3Sample.cpp for an example of this
If the call fails on the remote system, you will get back ID_RPC_REMOTE_ERROR. packet->data[1] will contain one of the values of RPCErrorCodes. packet->data[2] and on will contain the name of the function.
- Parameters:
-
const char* RakNet::RPC3::GetCurrentExecution |
( |
void |
|
) |
const |
Returns the currently running RPC call identifier, set from RegisterFunction::uniqueIdentifier Returns an empty string "" if none
- Returns:
- which RPC call is currently running
Returns the system address of the last system to send us a received function call Equivalent to the old system RPCParameters::sender
- Returns:
- Last system to send an RPC call using this system
RakNet::Time RakNet::RPC3::GetLastSenderTimestamp |
( |
void |
|
) |
const |
If the last received function call has a timestamp included, it is stored and can be retrieved with this function.
- Returns:
- 0 if the last call did not have a timestamp, else non-zero
bool RakNet::RPC3::IsFunctionRegistered |
( |
const char * |
uniqueIdentifier |
) |
|
Returns if a function identifier was previously registered on this system with RegisterFunction(), and not unregistered with UnregisterFunction()
- Parameters:
-
[in] | uniqueIdentifier | String identifying the function. |
- Returns:
- True if the function was registered, false otherwise
Called when a connection is dropped because the user called RakPeer::CloseConnection() for a particular system
- Parameters:
-
[in] | systemAddress | The system whose connection was closed |
[in] | rakNetGuid | The guid of the specified system |
[in] | lostConnectionReason | How the connection was closed: manually, connection lost, or notification of disconnection |
Reimplemented from RakNet::PluginInterface2.
OnReceive is called for every packet.
- Parameters:
-
[in] | packet | the packet that is being returned to the user |
- Returns:
- True to allow the game and other plugins to get this message, false to absorb it
Reimplemented from RakNet::PluginInterface2.

bool RakNet::RPC3::RegisterFunction |

Function |
functionPtr | |

) |
| | [inline] |
Register a function pointer as callable using RPC()
- Parameters:
-
[in] | uniqueIdentifier | String identifying the function. Recommended that this is the name of the function |
[in] | functionPtr | Pointer to the function. For C, just pass the name of the function. For C++, use ARPC_REGISTER_CPP_FUNCTION |
- Returns:
- True on success, false on uniqueIdentifier already used

) |
| | [inline] |
Register a slot, which is a function pointer to one or more instances of a class that supports this function signature When a signal occurs, all slots with the same identifier are called.
- Parameters:
-
[in] | sharedIdentifier | A string to identify the slot. Recommended to be the same as the name of the function. |
[in] | functionPtr | Pointer to the function. For C, just pass the name of the function. For C++, use ARPC_REGISTER_CPP_FUNCTION |
[in] | objectInstance | If 0, then this slot is just a regular C function. Otherwise, this is a member of the given class instance. |
[in] | callPriority | Slots are called by order of the highest callPriority first. For slots with the same priority, they are called in the order they are registered |
Sets the network ID manager to use for object lookup Required to call C++ object member functions via SetRecipientObject()
- Parameters:
-
[in] | idMan | Pointer to the network ID manager to use |

void RakNet::RPC3::SetRecipientObject |

networkID |
) |
|
Set the NetworkID to pass for all following calls to Call() Defaults to UNASSIGNED_NETWORK_ID (none) If set, the remote function will be considered a C++ function, e.g. an object member function If set to UNASSIGNED_NETWORK_ID (none), the remote function will be considered a C function If this is set incorrectly, you will get back either RPC_ERROR_CALLING_C_AS_CPP or RPC_ERROR_CALLING_CPP_AS_C

Send or stop sending a timestamp with all following calls to Call() Use GetLastSenderTimestamp() to read the timestamp.
- Parameters:
-
[in] | timeStamp | Non-zero to pass this timestamp using the ID_TIMESTAMP system. 0 to clear passing a timestamp. |
