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.
Header: #include <plugins/UnigineVrpnClient.h>

A class for the VRPN Plugin that allows receiving data about input devices sticks (for example, game-pad sticks).

VrpnAnalogDevice Class

Members


void setAnalogCallback ( const char * name ) #

Sets the world script callback function that receives data about input device sticks.
Notice
The callback function should be defined in the world script and receive 1 argument - an instance of the VrpnAnalogDevice class.
Source code (UnigineScript)
void callback_func(VrpnAnalogDevice device) {
    // function logic
}

Arguments

  • const char * name - Callback function name.

Examples

Source code (UnigineScript)
VrpnAnalogDevice vrpn_analog;

int init() {
	// create an instance of VrpnAnalogDevice
    vrpn_analog = new VrpnAnalogDevice("device_name@server_addr");
	// set a callback
    vrpn_analog.setAnalogCallback("analog_callback");
}

int shutdown() {
    delete vrpn_analog;
    return 1;
}

int update() {
    vrpn_analog.update();
    return 1;
}

// a callback function
void analog_callback(VrpnAnalogDevice device) {
    forloop(int i = 0; device.getNumChannels()) {
        log.message("Device analog channel %d: %lf\n",i,device.getChannel(i));
    }
}

const char * getAnalogCallback ( ) #

Returns a name of the world script callback function that receives data about input device sticks. The callback function should be defined in the world script and receive 1 argument - an instance of the VrpnAnalogDevice class.
Source code (UnigineScript)
void callback_func(VrpnAnalogDevice device) {
    // function logic
}

Return value

Callback function name.

double getChannel ( int channel ) #

Returns data received by the analog stick with the given number.
Notice
If the given stick haven't received data, the engine assertion will occur.

Arguments

  • int channel - Analog stick number in range [0;number_of_sticks - 1].

Return value

Returns data received by the analog stick with the given number.

int getNumChannels ( ) #

Returns the number of analog sticks that have received data.

Return value

The number of analog sticks that have received data. If no sticks have received data, 0 will be returned.

void update ( ) #

Updates the internal state of the device and receives input data.
Notice
This function should be called each frame.

VrpnAnalogDevice ( const char * name ) #

Constructor.

Arguments

  • const char * name - Path to the device in the format device_name@server_address.
