D3DXVECTOR2 structure (D3dx9math.h)

Note

The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.

Describes a two-component vector including operator overloads and type casts.

Syntax

typedef struct D3DXVECTOR2 {
  FLOAT x;
  FLOAT y;
} D3DXVECTOR2, *LPD3DXVECTOR2;

Members

x

Type: FLOAT

The x-component.

y

Type: FLOAT

The y-component.

Remarks

D3DXVECTOR2 Extensions

D3DXVECTOR2 has the following C++ extensions.

typedef struct D3DXVECTOR2
{
#ifdef __cplusplus
public:
    D3DXVECTOR2() {};
    D3DXVECTOR2( CONST FLOAT * );
    D3DXVECTOR2( CONST D3DXFLOAT16 * );
    D3DXVECTOR2( FLOAT x, FLOAT y );

    // casting
    operator FLOAT* ();
    operator CONST FLOAT* () const;

    // assignment operators
    D3DXVECTOR2& operator += ( CONST D3DXVECTOR2& );
    D3DXVECTOR2& operator -= ( CONST D3DXVECTOR2& );
    D3DXVECTOR2& operator *= ( FLOAT );
    D3DXVECTOR2& operator /= ( FLOAT );

    // unary operators
    D3DXVECTOR2 operator + () const;
    D3DXVECTOR2 operator - () const;

    // binary operators
    D3DXVECTOR2 operator + ( CONST D3DXVECTOR2& ) const;
    D3DXVECTOR2 operator - ( CONST D3DXVECTOR2& ) const;
    D3DXVECTOR2 operator * ( FLOAT ) const;
    D3DXVECTOR2 operator / ( FLOAT ) const;

    friend D3DXVECTOR2 operator * ( FLOAT, CONST D3DXVECTOR2& );

    BOOL operator == ( CONST D3DXVECTOR2& ) const;
    BOOL operator != ( CONST D3DXVECTOR2& ) const;


public:
#endif //__cplusplus
    FLOAT x, y;
} D3DXVECTOR2, *LPD3DXVECTOR2;

typedef struct D3DXVECTOR2_16F
{
#ifdef __cplusplus
public:
    D3DXVECTOR2_16F() {};
    D3DXVECTOR2_16F( CONST FLOAT * );
    D3DXVECTOR2_16F( CONST D3DXFLOAT16 * );
    D3DXVECTOR2_16F( CONST D3DXFLOAT16 &x, CONST D3DXFLOAT16 &y );

    // casting
    operator D3DXFLOAT16* ();
    operator CONST D3DXFLOAT16* () const;

    // binary operators
    BOOL operator == ( CONST D3DXVECTOR2_16F& ) const;
    BOOL operator != ( CONST D3DXVECTOR2_16F& ) const;

public:
