JSGetAxisCoeff3
Axis value retrieving
Usage
#include <jsw.h>
double JSGetAxisCoeff(
js_data_struct *jsd,
int n
)
Arguments
- jsd
-
Specifies the pointer to the joystick data structure, which should have been set up by a prior call to JSInit.
- n
-
Specifies the axis number.
Overview
The JSGetAxisCoeff function fetches the last updated value of the specified axis n on the jsd structure.
Return value
The JSGetAxisCoeff function returns the coefficient value of the joystick axis number in a range of -1.0 to 1.0 but does not take into account if the axis is currently within its null zone. The return value also does not make a distinction between success or error (error as if the axis was not valid).
