Um... you might want to start with the ''for beginners'' link above

Most games these days are programmed with C++, but you can use any language to program a game. The tools that go into making a game - editors and such - can be programmed with C, C++, VB, Pascal etc.

DirectX is an api not a language - so C++ or DX is not much of a question. DX can be used to handle the mouse, there are other ways.

It really depends on your platform you are developing for. If you are using windows your code will call various DirectX funcions to perform Input, Sound, or Graphics unless you use OpenGL for graphics or OpenAL for sound. It realy depends on what the developer chooses to use.

DirectX, OpenGl and OpenAL are all APIs that a programmer can use with many languages.

Of couse a developer could just forget using APIs and write code directly to the hardware like dos programs do but why reinvent the wheel. Plus Windows doesn''t look kindly on programmers poking around at the hardware it usally not worth the effort fighting windows

As for what language the APIs are written in it could be anything. I would think DirectX is written in C/C++ but I don''t know for sure.

I think you are lacking in the understanding of a few things. DirectX is not a programming language. It is incorrect to say "I program in DirectX." DX is a library that you can use. Granted, you can use it from different languages, but you are still using the language to make the calls.

Most games are done in a bastardized C/C++ hack together. I have NEVER seen any pure C++ code used in a full scale project. It could be done, but SO MANY schools and such still teach procedural coding with C++ libraries and barely touch on the oop stuff.

But to summarize - most games are done in C/C++ using DirectX or OpenGL libraries for the graphics.
