// Class : AnalogNode
|
|
// Description : This is the primary interface to analog controls like
|
|
// sliders and joysticks associated with a ClientBase.
|
|
// This creates a node that connects to the named analog
|
|
// device, if it exists, and provides hooks to the user
|
|
// to read the state of any of the sequentially numbered
|
|
// controls associated with that device.
|
|
//
|
|
// Each control can return a value ranging from -1 to 1,
|
|
// reflecting the current position of the control within
|
|
// its total range of motion.
|
|
//
|
|
// The user may choose up to two analog controls to
|
|
// place on the data graph as the two channels of an
|
|
// xy datagram, similarly to the way a mouse places its
|
|
// position data. In this way, an AnalogNode may be
|
|
// used in place of a mouse.
