Writing games with an off screen bitmap

Question

I want to start writing games for Windows 8 apps in C++.

I have already written a printed circuit design program using direct2d (Simple_PCBCAD)

I also used to write Z80 programs for the Sinclair Spectrum in the 1980's.

So I come from a background of using the screen like a bitmap.

From what I have seen this is very difficult to do with direct2d.

I guess I could write a game using the basic direct2d functions of filled shapes but this is very different to what I am used to.

Is there a way I can use bit mapped memory then dump it to the screen in one go ?

Hi nigelwright7557,

Welcome to MSDN forum!

I could only find the method ID2D1Bitmap::CopyFromMemory.

I hope it is helpful.

If i misunderstand you, please feel free let me know.

Regards!

Answer 2

Use Direct3D, even for 2D games. Find a good book and tutorials if you are just getting started. Check out the DirectX Tool Kit which is an easy to use XNA clone library for c++.  With the DirectXTK spritebatch and WIC texture loaders you will be drawing bitmaps (sprites) in no time.

I downloaded the simplesample project and used that as a basis for a game.

I created a texture then a shader and wrote to the texture.

I displayed the texture as fullscreen.
