Slave Class

WarningThe scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScript (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.

Warning

The functionality described in this article is not available in the Community SDK edition.
You should upgrade to Sim SDK edition to use it.

Slave Class

Members

int getMasterNodeID ( int slave_node_id ) #

Returns the ID of a dynamic node on the Master by its local ID on the Slave. A Slave does not create an exact copy of a node created on the Master, their IDs do not match. So, knowing an ID of a local copy of a node created on the Master, you can easily find its original on the Master. This can be used in user messages, when you need to apply some specific modifications to source node on the Master.

Arguments

int slave_node_id - Node's ID on the Slave.

Return value

ID of the node on the Master.

int getSlaveNodeID ( int master_node_id ) #

Returns the local ID of a dynamic node on the Slave by its ID on the Master. A Slave does not create an exact copy of a node created on the Master, their IDs do not match. So, if you created a node on the Master and then called the Syncker::Master::createNode() method, you can easily find its copy on the current Slave. This can be used in user messages, when you need to apply some specific modifications to a Slave's copy of a node, that was created on the Master.

Arguments

int master_node_id - Node's ID on the Master.

Return value

ID of the node on the Slave.

void addSyncNode ( Node node, int master_node_id ) #

Enables synchronization of parameters of the given node via the UDP protocol.

NoticeScene nodes are not synchronized by default, this method is used to add a particular node to the synchronization queue.

Arguments

Node node - Node to synchronize.
int master_node_id - ID of the node on the Master.

void addSyncNodeID ( int slave_node_id, int master_node_id ) #

Enables synchronization of parameters of the given node via the UDP protocol.

NoticeScene nodes are not synchronized by default, this method is used to add a particular node (by its id) to the synchronization queue.

Arguments

int slave_node_id - ID of the node on the Slave.
int master_node_id - ID of the node on the Master.

bool removeSyncNode ( Node node ) #

Removes the specified node from the synchronization queue.

Arguments

Node node - Node to be removed.

Return value

true if the node was successfully removed from the synchronization queue; otherwise, false.

bool removeSyncNodeID ( int slave_node_id ) #

Removes the node with the given number from the synchronization queue.

Arguments

int slave_node_id - Node number in the synchronization queue.

Return value

true if the node was successfully removed from the synchronization queue; otherwise, false.

long getID ( ) #

Returns the current ID of the Slave.

Return value

ID of the slave combined as follows: IP address (32 bits) + port number (16 bits).

void setSkipFlags ( int flags ) #

Sets the skip flags enabling you to ignore certain information from the Master.

Arguments

int flags - A combination of skip flags to be used, for example:
Source code (UnigineScript)
```
slave.setSkipFlags(SLAVE_GAME | SLAVE_WORLD_LOAD | SLAVE_USER_DATA);
```

int getSkipFlags ( ) #

Returns the current skip flags combination enabling you to ignore certain information from the Master.

Return value

A combination of currently used skip flags.

Variable addCallback ( int callback, Variable func ) #

Adds a callback of the specified type. Callback functions can be used to determine actions to be performed when sending or receiving user messages, as well as when changing settings on the Master or a Slave. The signature of the callback function can be one of the following:

Source code (UnigineScript)

// for the Syncker.Slave.SESSION_STARTED type
void callback_function_name(void);

// for the Syncker.Slave::SESSION_FINISHED type
void callback_function_name(void);

// for the Syncker.Slave.MASTER_CONNECTED type
void callback_function_name(void);

// for the Syncker.Slave.MASTER_DISCONNECTED type
void callback_function_name(string reason);

// for the Syncker.Slave.NODE_LOADED type
void callback_function_name(Node node);

Arguments

int callback - Callback type. One of the following values:
Variable func - There are two ways you can specify a callback function:
- by name - when you call a function, declared globally.
- by ID - when you call a member function of a certain class.
  Notice
  An ID can be obtained via functionid().

Return value

Number of the last added callback of the specified type, if the callback was added successfully; otherwise, -1.

bool removeCallback ( int callback, Variable func ) #

Removes a given callback from the list of callbacks of the specified type. Callback functions can be used to determine actions to be performed when sending or receiving user messages, as well as when changing settings on the Master or a Slave.

Arguments

int callback - Callback type. One of the following values:
Variable func - There are two ways you can specify a callback function:
- by name - when you call a function, declared globally.
- by ID - when you call a member function of a certain class.
  Notice
  An ID can be obtained via functionid().

Return value

true if the position callback with the given ID was removed successfully; otherwise false.

void clearCallbacks ( int callback ) #

Clears all added callbacks of the specified type. Callback functions can be used to determine actions to be performed when sending or receiving user messages, as well as when changing settings on the Master or a Slave.

Arguments

int callback - Callback type. One of the following values:
