Hello,

I'm trying to make a wrapper class for Direct2D, this is what I've now.

-DirectX classes

InitDX
BitMapDX
TextDX

In the InitDX, I make the factory and the com etc, but the bitmap and text classes need the factory, so should I use class friendly ship or is it better to use a function to get the static pointer of a factory?

Further the BitMap class will load a bitmap and then you can draw it or not etc, but how if I would like to load 10 bitmaps, I've to make 10 variables of bitmaps, but next time it could be 26 bitmaps. An array would be nice. But I guess that's not possible for this?

I did not code anything yet, since this is just my design.

Thanks for reading.

Your base factory could be a singleton (static pointer setup) as one method of setting up. Everyone has their own opinion about singletons, so its up to you to choose that method if you want it.

If you plan to allow other extensions to be able to render everything you will want to virtualize any major function and allow it to be overridden by a lower base. (DirectX, OpenGL, etc.)

As for the Bitmap question, just use a container of a type. If you're using a custom class like; CCustomBitmap, you could use any of the container types to hold an array of them ex.

std::list<CCustomBitmap> m_vBitmaps;
std::vector<CCustomBitmap> m_vBitmaps;

(or std::map, std::hash

There are a bunch of other containers, or you can code your own.

Thanks that helped, I just made the pointer static and a GetPointer function. That works now.

So my next problem is that I made a CBackground class and for the background Im just drawing a bitmap as background. Then at top of that I draw the other pictures etc. But how if I would like a map to be chaning, for example in some games when you walk right the map changes to, it goes right. How do they do this?

Another thing, the D2 examples all uses .rc files, I would like to load from a directory is this possible?

Thanks.

You can load textures from resources or files. Look at:
D3DXCreateTexture
D3DXCreateTextureFromFile
D3DXCreateTextureFromFileEx
D3DXCreateTextureFromFileInMemory
D3DXCreateTextureFromFileInMemoryEx
D3DXCreateTextureFromResource
D3DXCreateTextureFromResourceEx

If you want to map to scroll you will have to code the texture to scroll with the movement of your focused object. (Whatever the camera is fixed to.) At the end of the textures you will need to begin drawing the next.

Some concepts:

You should be able to find other info on scrolling textures via Google if you need more.

Well, I'm creating further and further, but im not sure if my design is done well. Since I need lots of static pointers. Ill show the classes.

Why are you using static pointers for color / bitmap?

[NoMercy]

Because I use another instance of a class. I'm not sure if I can save that one somewhere or something.
