Estrutura D3DXVECTOR2 (D3DX10Math.h)

Observação

A biblioteca do utilitário D3DX10 foi preterida. Em vez disso, recomendamos que você use DirectXMath .

Descreve um vetor de dois componentes, incluindo sobrecargas de operador e conversões de tipo.

Sintaxe

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

Membros

x

Tipo: FLOAT

O componente x.

y

Tipo: FLOAT

O componente y.
