D3d Texture Wrapper == ARRRGGGGHHH

This is getting too frustrating for me. I've tried to figure this out myself and I've tried to stop myself from pasting so much code here but I don't have a choice:

Code:

---

// SPRITE.H

struct SPRITE_INFO
{
        SPRITE_INFO();
        ~SPRITE_INFO();
       
        SPRITE_INFO( const SPRITE_INFO& temp );
        SPRITE_INFO& operator = ( const SPRITE_INFO& temp );

        short Texture;
        D3DXVECTOR3* Position;
        D3DCOLOR Color;

        void SetColor( WORD r, WORD g, WORD b );
        void SetPosition( float x, float y, float z );
};

struct TEXTURE
{
        TEXTURE( IDirect3DDevice9* Device, LPCSTR sFilename, float Dim_X, float Dim_Y );
        ~TEXTURE();
       
        TEXTURE( const TEXTURE& temp );
        TEXTURE& operator = ( const TEXTURE& temp );

        IDirect3DTexture9* Texture;
        D3DXVECTOR3* Center;
        LPCSTR Filename;
};

class SPRITE
{
public:
        SPRITE();
        SPRITE( IDirect3DDevice9* Dev );
        ~SPRITE();

        ID3DXSprite* Sprite;

        std::vector<TEXTURE> Texture;
        std::vector<SPRITE_INFO> SpriteInfo;
       
       
        void SetDevice( IDirect3DDevice9* Dev );
        void OnLostDevice();
        void OnResetDevice();
        void AddTexture( LPCSTR Filename, float Dim_X, float Dim_Y );
        void Draw();

private:
        IDirect3DDevice9* Device;
        bool inited : 1;
};//testsprite( gd3dDevice );

This is my first attempt for a simple wrapper for a 2D game. It compiles fine but I get a box popup when I run it titled "Unexpected error encountered" and says "File:"... and thats it. When I debug, it says

"There is no source code available for the current location". If I can't get this to work, any dreams I have of making a 2D game with textures will perish.

I much appreciate any help.

If you are compiling in anything except unicode the DX_TRACE and other functions won't report correctly.

You can still get information by using DXGetErrorString() and others like it.

Code:

---

TEXTURE::TEXTURE( const TEXTURE& temp )
{
        Center = new D3DXVECTOR3;
        *Center = *temp.Center;


        IDirect3DDevice9* Device;
        Texture->GetDevice( &Device );
        HR( D3DXCreateTextureFromFile( Device, Filename, &Texture ) );

        *Texture = *temp.Texture;
};

---

This looks suspicious. D3DXCreateTextureFromFile() will create a new IDirect3DTexture9 interface pointer for you. Then you proceed to assign it to a pointer in temp. You just leaked one COM resource right there. If you were just going to shallow copy the one in temp to the current one why did you ask D3DX to create a new one? Also you don't need semicolon's after the closing braces of functions.

Code:

---

HR( Device->SetRenderState(D3DRS_ALPHAREF, 10 ) );
HR( Device->SetRenderState(D3DRS_ALPHAFUNC, D3DCMP_GREATER ) );

// The following code is used to setup alpha blending.
HR( Device->SetTextureStageState( 0, D3DTSS_ALPHAARG1, D3DTA_TEXTURE ) );
HR( Device->SetTextureStageState( 0, D3DTSS_ALPHAOP, D3DTOP_SELECTARG1 ) );
HR( Device->SetRenderState( D3DRS_SRCBLEND, D3DBLEND_SRCALPHA ) );
HR( Device->SetRenderState( D3DRS_DESTBLEND, D3DBLEND_INVSRCALPHA ) );

---

Are you trying to do alpha testing here or alpha blending? Enabling both for one object seems a bit odd.

Code:

---

HR( Sprite->Begin( D3DXSPRITE_OBJECTSPACE | D3DXSPRITE_DONOTMODIFY_RENDERSTATE ) );

---

This may draw nothing depending on how you have your system setup.

Code:

---

void SPRITE::AddTexture( LPCSTR Filename, float Dim_X, float Dim_Y )
{
        Texture.push_back( TEXTURE( Device, Filename, Dim_X, Dim_Y ) );
};

---

Why not have a texture manager that returns a texture ID when you add textures to it's list? Then you store the ID in the Sprite object and during render you ask for the texture based on the ID you were given at creation time.

Why have the sprite keep track of the actual texture objects? Isn't animation just a list of texture ID's or texture u,v's?
