Sets the current IG status.Arguments
- int status - IG status. The following values are supported:
- 0 - normal
- 1-255 - an error has occurred
int getIGStatus ( ) const#
Returns the current IG status.Return value
IG status. The following values are supported:- 0 - normal
- 1-255 - an error has occurred
void setSynchronous ( bool synchronous ) #
Sets a value indicating if synchronous operation mode is currently enabled (when disabled, asynchronous mode is used).Arguments
- bool synchronous - true to enable synchronous operation mode; false - to use asynchronous mode.
bool isSynchronous ( ) const#
Returns a value indicating if synchronous operation mode is currently enabled (when disabled, asynchronous mode is used).Return value
true if synchronous operation mode is currently enabled; otherwise, false.bool isInterpolation ( ) const#
Returns a value indicating if interpolation and extrapolation are enabled.Return value
true if interpolation and extrapolation are enabled; otherwise, false.unsigned int getIGFrame ( ) const#
Returns the number of the current frame for the IG.Return value
Current IG frame number.unsigned int getHostFrame ( ) const#
Returns the number of the current frame for the Host.Return value
Current Host frame number.double getTime ( ) const#
Returns the IG's simulation time.Return value
IG's simulation time, in seconds.double getLastReceivedHostTime ( ) const#
Returns the last received Host time (timestamp value in "IG Control").Return value
Last received Host time, in seconds.void * addOnConnectCallback ( Unigine::CallbackBase * func ) #
Adds a callback function to be fired when the Host has connected.Arguments
- Unigine::CallbackBase * func - Callback pointer.
Return value
ID of the last added connect callback, if the callback was added successfully; otherwise, nullptr. This ID can be used to remove this callback when necessary.bool removeOnConnectCallback ( void * id ) #
Removes the specified callback from the list of Connect callbacks.Arguments
- void * id - Connect callback ID obtained when adding it.
Return value
True if the Connect callback with the given ID was removed successfully; otherwise false.void * addOnReceivePacketCallback ( int cigi_opcode, Unigine::CallbackBase1 * func ) #
Sets a callback function to be fired when a packet of the specified type has been received from the Host.Arguments
- int cigi_opcode - CIGI data packet opcode. One of the CIGI_OPCODE_* values.
-
Unigine::CallbackBase1 * func - Callback pointer. The callback function must have the following signature:
(Unigine::Plugins::IG::CIGI::CigiHostPacket *packet)
Return value
ID of the last added Receive Packet callback, if the callback was added successfully; otherwise, nullptr. This ID can be used to remove this callback when necessary.bool removeOnReceivePacketCallback ( void * id ) #
Removes the specified callback from the list of Receive Packet callbacks.Arguments
- void * id - Receive Packet callback ID obtained when adding it.
Return value
true if the Receive Packet callback with the given ID was removed successfully; otherwise false.void * addOnSendPacketCallback ( int cigi_opcode, Unigine::CallbackBase4 * func ) #
Sets a callback function to be fired right before sending a response to a request. This can be used to send additional data required by a host (e.g., velocities of the point of intersection for LOS/HAT queries which is useful in case of landing on a moving platform).A callback function has the following signature:
(bool &ret, IG::CIGI::CigiIGPacket *response, IG::CIGI::CigiHostPacket *request, IG::IGIntersection *intersection)
- ret - boolean value indicating if the packet is to be sent or not;
- response - the packet to be sent;
- request - request for which a packet is to be sent as a response (can be nullptr);
- intersection - additional info on intersection (if necessary).
