Message1. New BUG, QD3DVector is wrong
#3594
Posted by: JohnK 2004-03-26 05:55:44
I found out that QD3DVector is declared incorrectly. The current declaration is

QD3DVector
  DVX SINGLE
  DVY SINGLE
  DVZ SINGLE
  X SINGLE
  Y SINGLE
  Z SINGLE

Should be:
QD3DVector
  X SINGLE
  Y SINGLE
  Z SINGLE

Why? The actual Microsoft declaration is A UNION !!!
typedef struct _D3DVECTOR {
    union {
        D3DVALUE x;
        D3DVALUE dvX;
    };
    union {
        D3DVALUE y;
        D3DVALUE dvY;
    };
    union {
        D3DVALUE z;
        D3DVALUE dvZ;
    };
} D3DVECTOR, *LPD3DVECTOR;

That is you can use this code:

DIM Camera AS QD3DVector
Camera.x = 1
Camera.y = 0
Camera.z = 0.5

But don't use:

Camera.dvx = XXX
Camera.dvy = XXX
Camera.dvz = XXX

Or maybe you should just declare your own

TYPE QVector3D
  DVX SINGLE
  DVY SINGLE
  DVZ SINGLE
  X SINGLE
  Y SINGLE
  Z SINGLE
END TYPE

DIM Camera AS QVector3D
