Complicated dll struct

[JRowe]

I'm working on a new project, integrating a 3D engine that just became available. I was wondering if anyone could take a stab at creating the following struct using DllStructCreate.

struct D3DXVECTOR3
{
 float x,y,z;
 D3DXVECTOR3(float x=0.0f,float y=0.0f,float z=0.0f)
 {
    this->x = x;
    this->y = y;
    this->z = z;
 }
 D3DXVECTOR3& operator+= (const D3DXVECTOR3&);
 D3DXVECTOR3& operator-= (const D3DXVECTOR3&);
 D3DXVECTOR3& operator*= (float);
 D3DXVECTOR3& operator/= (float);
 D3DXVECTOR3 operator+ () const;
 D3DXVECTOR3 operator- () const;
 D3DXVECTOR3 operator+ (const D3DXVECTOR3&) const;
 D3DXVECTOR3 operator- (const D3DXVECTOR3&) const;
 D3DXVECTOR3 operator* (float) const;
 D3DXVECTOR3 operator/ (float) const;
 BOOL operator== (const D3DXVECTOR3&) const;
 BOOL operator!= (const D3DXVECTOR3&) const;
};

The code I'm using it in is expecting a D3DXVector3 struct to be passed as one of the parameters. Using the following, I crash the 3D engine.

Func iCameraLocationSet($pCamera, $fX, $fY, $fZ)
        $D3DXVector3 = DllStructCreate("float X;float Y;float Z")
            DllStructSetData($D3DXVector3, "X", $fX)
            DllStructSetData($D3DXVector3, "Y", $fY)
            DllStructSetData($D3DXVector3, "Z", $fZ)
        DllCall($3iDLL, "none:cdecl", "iCameraLocationSet", "ptr", $pCamera, "ptr", $D3DXVector3)
EndFunc

Is there an easy way to set this up?

I've gotten the engine to initialize, etc, just haven't been able to use the structs for positioning. As soon as that gets figured out, I only have around 180 or so functions left to wrap in. Any help is appreciated

Edit: It appears I got ahead of myself. the function iCameraLocationSet is expecting a pointer to a valid camera object. I'd assumed that there was such a pointer being created; I was wrong. That being the case, I've gone back to figure out where the heck I went wrong, and I'll be back later. Thanks for any input, however!

$D3DXVector3 = DllStructCreate("float X;float Y;float Z")

this line is correct, but you have an error in your DLLCall. You forgot to call DLLStructGetPtr

DLLCall(... , 'ptr', DLLStructgetPtr($D3DXVector3))

Wow, brainfart. Thanks man.
