XMUSHORTN2::XMUSHORTN2(float,float) function (directxpackedvector.h)

  • Article

Initializes a new instance of XMUSHORTN2 from two normalized float arguments.

This constructor initializes a new instance of XMUSHORTN2 from two normalized float arguments.

Note  This constructor is only available under C++.
 

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;
