XMBYTE2 Structure

A 2D vector where each component is a signed integer, 8-bits (1 byte) in length.

If you are programming in C++, you can use the constructors and operator methods of this structure.

Note

See DirectXMath Library Type Equivalences for information about equivalent D3DDECLTYPE, D3DFORMAT, and DXGI_FORMAT objects.

Syntax

struct XMBYTE2  

Remarks

The fields in the XMBYTE2 structure are declared as follows:

struct XMBYTE2
{
    union
    {
        struct
        {
            int8_t x; // Signed 8-bit integer value in the range [-127, 127] 
                      // describing the x-coordinate of the vector.
            int8_t y; // Signed 8-bit integer value in the range [-127, 127] 
                      // describing the y-coordinate of the vector.
        };
        uint16_t v; // Unsigned 16-bit integer representing the 2D vector.
    };  

You can use XMLoadByte2 to load XMBYTE2 into instances of XMVECTOR.

You can use XMStoreByte2 to store instances of XMVECTOR into an instance of XMBYTE2.
