C plus plus version

We discuss the C++ design and coding standards in here. A wiki is much handier then a forum or PM's for this.

Language switch
You wonder why we're switching? Because VB is for simple, gui based programs. Darwinbots is nor a simple program, nor gui based. In contrary C++ is a powerfull language, but it has a higher development cost.
C++ design
General concepts
- Class based approach. In some cases, procedural in others. It's a value decision I'll make as I port the code.
- Portable code. Where possible. Preferably in house or free library wrappers for non portable functions, such as multithreading and OS timers.
Structure
See the present VB code
- The VB stucture is not a good C++ structure. VB and C++ are totally diffrent languages.
- Only in the microscopic sense.
- Could you please explain? To me they seem totally diffrent.
- When you view the way in which the VB modules interact, that's exactly the same way the C++ modules will interact.
- Wether you paint in black and white or in color, shapes are going to be the same.
- Shapes and colors have very little to do with the structure of a program.
- Only in the microscopic sense.
- User Interface (Fox Toolkit)
- Simulation sub window (3D - OpenGL)
- Darwin (the simulation engine)
- Tie
- Robot
- Sense
- Veg
- Robot
- Tie
To be used everywhere:
- Vector_4 (using uBLAS) Present vector class is from this gamedev.net article. I'll use whichever is fastest, feel free to perfrom benchamrks
- Matrix_4 (also using uBLAS) See above
- Random (using 'srand()' and 'rand()') See the chapter on random numbers
- Object (the base class) Depends on the class
C++ coding standards
- C++ C++ libraries where such libraries do what I want them to do, C libraries otherwise. Another value decision. All C librairies are included in C++. Mixing C and C++ isn't the easiest task, however OO C++ and procedural C++ can be mixed easily. I agree, but I've been having some trouble with various C++ libraries that immediatly goes away when I switch to the C versions. Might just be my compiler MSVC++ 6.0 Prolly, it's crap. :-P Try the MinGW version of the gcc compiler.
- Four spaced tabs - Aye.
- External librairies when possible (ie. Boost) Internal libraries where possible, to decrease the number of code dependancies, except where external libraries perform the job faster/more comoprehensively than internal libraries can.
- Use the 80 character line If you insist... Yup, I do. ;-)
- Fox Toolkit
- OpenGL
