|
|
// - init is called immediately, the graphics module may not exist yet
|
|
// - start is called after the graphics module is initialized, can be used to set up graphics objects
|
|
// - getDisplayFrequency may return 0.f if the information is unavailable.
|
|
// - For isDown, changed can be set to false if change information is unavailable or inconvenient.
|
|
// - getAxis may write 4 floats to the output value. The expected number is a constant (see axisCounts in l_headset).
|
|
// - In general, most input results should be kept constant between calls to update.
