XMUSHORTN2::XMUSHORTN2(float,float) function (directxpackedvector.h)
Initializes a new instance of XMUSHORTN2
from two normalized float
arguments.
This constructor initializes a new instance of XMUSHORTN2 from two
normalized float
arguments.
Syntax
void XMUSHORTN2(
float _x,
float _y
) noexcept;
Parameters
_x
A normalized value for the x-coordinate of the vector.
This argument should be between 0.0 and 1.0; during the instantiation of an
instance of XMUSHORTN2
, it is multiplied by 65535.0f
and
then stored as the x member of the structure.
_y
A normalized value for the y-coordinate of the vector, the y of the
new instance of XMUSHORTN2
.
This argument should be between 0.0 and 1.0; during the instantiation of an
instance of XMUSHORTN2
, it is multiplied by 65535.0f
and
then stored as the y member of the structure.
Return value
None
Remarks
All input values,_x and _y are clamped to a range of 0.0 to 1.0.
The following pseudocode demonstrates the operation of this constructor:
XMUSHORTN2 instance;
_x1=min( max( _x, 0.0 ), 1.0 );
_y1=min( max( _y, 0.0 ), 1.0 );
_x1 = round( _x1 * 65535.0f);
_y1 = round( _y1 * 65535.0f);
instance._x = _x1;
instance._y = _y1;
