XMUBYTE4::XMUBYTE4(float,float,float,float) function (directxpackedvector.h)

Initializes a new instance of XMUBYTE4 from four float arguments.

This constructor initializes a new instance of XMUBYTE4 from four float arguments.

Syntax

void XMUBYTE4(
  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 XMUBYTE4 instance.

_y

Value of the y-coordinate of the vector, the y member of the new XMUBYTE4 instance.

_z

Value of the z-coordinate of the vector, the z member of the new XMUBYTE4 instance.

_w

Value of the w-coordinate of the vector, the w member of the new XMUBYTE4 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 [0, 255.0].

The following pseudocode demonstrates the operation of this constructor:

	XMUBYTE4 instance;

	instance.x = (uint8_t)min( max( _x, 0.0 ), 255.0 );
	instance.y = (uint8_t)min( max( _y, 0.0 ), 255.0 );
	instance.z = (uint8_t)min( max( _z, 0.0 ), 255.0 );
	instance.w = (uint8_t)min( max( _w, 0.0 ), 255.0 );
