XMBYTE4::XMBYTE4(float,float,float,float) function (directxpackedvector.h)

  • Article

Initializes a new instance of XMBYTE4 from four float arguments.

This constructor initializes a new instance of XMBYTE4 from four float arguments.

Note  This constructor is only available under C++.
 

Syntax

void XMBYTE4(
  float _x,
  float _y,
  float _z,
  float _w
) noexcept;

Parameters

_x

Value of the x-coordinate of the vector, the x member of the new XMBYTE4 instance.

_y

Value of the y-coordinate of the vector, the y member of the new XMBYTE4 instance.

_z

Value of the z-coordinate of the vector, the z member of the new XMBYTE4 instance.

_w

Value of the w-coordinate of the vector, the w member of the new XMBYTE4 instance.

Return value

None

Remarks

The magnitude of each argument to the constructor will be clamped to the range supported by an 8-bit signed integer [-127.0, 127.0].

The following pseudocode demonstrates the operation of this constructor:


	XMBYTE4 instance;

	instance.x = (int8_t)min( max( _x, -127.0 ), 127.0 );
	instance.y = (int8_t)min( max( _y, -127.0 ), 127.0 );
	instance.z = (int8_t)min( max( _z, -127.0 ), 127.0 );
	instance.w = (int8_t)min( max( _w, -127.0 ), 127.0 );
