D3DXVECTOR2 structure

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 has the following C++ extensions.
