I'm trying to find the ideal gaming library for 3D game development, ideal graphics, ideal everything, shall I choose OpenGL or DirectX, or something else? what is the best at the moment?

You're looking to spark a "Which language is best" war...


Q: What is the best programming language/OS? What programming language/OS should I learn?
A:All of them. And none of them. You might as well be asking "What is the best kind of vehicle?" Because the answer for both questions is "It depends on your needs and what personally suites you the best." C, C++, C#, Objective-C, Cocoa, F#, Visual Basic, Python, JAVA...

Are all good languages. They all have their pros and cons. They each have their strengths and weaknesses. Some have stronger footholds in some markets than others. Do you want to write for iPhone/iPad then you need Objective-C. Do you want to write for generic mobile phone use then you need JAVA. And so on. If you have no idea what area of programming you want to move to (Gaming, Financial, Windows, Macintosh, Cell phones) then nobody can advise you on a language. Personally, I would point you to C# because, like it or not, Microsoft owns the desktop computer market and C# will teach you good habits of design, OOP (Object Oriented Programming) design, inheritance and so on: Concepts that translate well to all other OOP languages.

The OS is a by-product of the type of coding you want to do, which in turn dictates the language you need, which then decides the operating system you probably need. Not the other way around.

Do you want to code apps for iOS devices like the iPad and iPhone? Then you need a Macintosh to do it right. Are you hankering to do machine vision programming? Industrial robot control? Financial applications?

What are your programming goals? Do you want to market $9.99 desktop applications to the masses? Do you want to make control systems for helicopters? XBox games requires the .NET XNA framework so you are now in Windows. Do you want to do embedded controls for automotive computers? Do you just love MS Office and love to make extensions for it? Do you want to work on web apps or desktop apps or mobile apps?

Do you now see why we can't even begin to tell you what is best for you? Only you know what you like and what you don't like. Only you know what area of programming is interesting to you. If you ask me for advice I might tell you video processing for the movie industry is great so you should get a Mac. Someone else is going to tell you cool stories of working on CSI lab equipment so you should do C embedded stuff.

The short answer for this question is: Get in touch with your own wants and needs then think for yourself.

Join these discussions on the topic:
Which coding language?
VB6 is dead
C# or C++?

Ok sorry for being unspecific, I'm looking to develop 3D games for windows, I own a windows 7 machine, I'm looking to develop any type of 3D games from MMORPG's to FPS (first person shooters), anything interests me in this field, for windows, what is the best programming language for this and what is the best library for this?

[tlhIn`toq]

Different game types, different engines.

Sounds like you need to get your feet wet first, so probably C# and XNA. Then experience in the genre will put you in contact with others more devoted just to games.

Games are pretty much the hardest thing to write, so don't start there if you don't already have a solid command of the language and underlaying OOP principals.

My standard beginner resources post

We have a tutorials section and a learning C# series of articles.

First learn the language by working 2-5 "Learn C# in 30 days" type books cover to cover. Do a couple hundred on-line tutorial projects where you build what you're told to build, the way you are told to build it WITH AN EXPLANATION OF WHY so you can learn.

There are three routes people seem to take when learning programming.

• Just start trying to create programs
  
• Start taking apart other programs and try to figure out the language by reverse engineering
  
• Follow a guided learning course (school or self-teaching books)

For the life of me I can't figure out why people try 1 & 2. I strongly suggest taking the guided learning approach. Those book authors go in a certain order for a reason: They know what they're doing and they know the best order to learn the materials.

Where do I start?

You start by learning a coding language FIRST.
Learn to plan before you type.
THEN you start designing software with a purpose.


If this sounds like you

You need to start there. I can't say "I have little experience in speaking Russian, but I have been assigned to write a mystery novel in Russian. Can you help me?"

We can help you by saying "First learn basic programming and the language of C#. Then take on assignments." Could someone here write this program for you? Sure. Could someone here map out all the processes you need to follow and do the Software Design part of this in the slim hope you could code it from there? Sure. But we don't volunteer to do the job that you're either getting paid for, or getting a grade for. You may want to read this.

For now, just work on the lessons. Do a self-teaching book from cover to cover. Then consider writing a program.

Don't try to create a useful working program to fit a need of yours (or a for-pay contract) as your introduction to coding project. When you are learning to code you don't know enough to code a program, let alone know how to engineer the architecture of a program. It would be like saying "I don't know how to read sheet music, or play an instrument. I think I'll write a 3 act opera as my first learning experience."

I don't say this to be mean. We've seen lots of new coders take this approach and we know it doesn't work. Trying to design your own programs before you understand the basics of the code language you've chosen just leads to problems, frustrations, and 'swiss-cheese' education (lots of holes).

Otherwise, you can just jump to the resources here:
Some of the tutorials below are for C# or Java not C, C++, VB.NET [...]. But the conceptual stuff of classes, object oriented design, events etc. are not language specific and should give you enough guidance in theory of program development for you to be able to look-up specific code example in your chosen coding language.

I already have a background in programming from this other software/technology/lanugage so I don't think I need to do tutorials

Here's how I look at doing tutorials even if one has a coding background that makes one think they don't need to do tutorials:

• If one's background really is enough to not need the tutorials, then they won't take long - So what's the harm?
  
• If the tutorials do take a while, then it might be time to re-think how much of one's old experience really applies to the new technology.
  
• There's no down-side. Every tutorial/series teaches something in a new way. Maybe you pick up a neat trick or a different approach to something that you already knew.

The stages of asking for homework help on a forum



But honestly, just typing away and seeing what pops up in Intellisense is going to make your self-education take 20 years. You can learn by trying to reverse engineer the language through banging on the keyboard experimentation - or you can learn by doing the tutorials and following a good "How to learn C#" book. There are so many great "How do I build my first application" tutorials on the web... There are dozens of "Learn C# in 21 days", "My first C# program" type books at your local book seller or even public library.

Beginner:

C# learning series right here on Dream in code

MSDN Framework Development Guide

C# Reading list by Eric Lipert

C# Fundamentals: Development for absolute beginners (video series)
Build a Program Now! in Visual C# by Microsoft Press, ISBN 0-7356-2542-5 is a terrific book that has you build a Windows Forms application, a WPF app, a database application, your own web browser.

Martyr2's mega project ideas list is a great place to start on developmental projectst that you can learn from; rather than trying to make something complex like a game as a self-teaching tool {that never works for anyone}

Visual Studio Keyboard Shortcuts

D.I.C. C# Resource page Start here
Intro to C# online tutorial then here...
C# control structures then here.
MSDN Beginner Developer video series
MSDN video on OOP principals, making classes, constructors, accessors and method overloading
MSDN Top guideline violations, know what to avoid before you do it.
Design patterns as diagrams

I hate sending people to another site when we have such good tutorials here, but this series shouldn't be overlooked.
Programming OOP in C# - Part 1
Programming OOP in C# - Part 2
Programming OOP in C# - Part 3
Programming OOP in C# - Part 4
Programming OOP in C# - Part 5

Writing a text file is always one of the first things people want to do, in order to store data like high-scores, preferences and so on.
Writing a text file tutorial.
Reading a text file tutorial.
.Split()ing a string

Have you seen the 500+ MSDN Code Samples? They spent a lot of time creating samples and demos. It seems a shame to not use them.



Intermediate:
OOP design patterns


Microsoft Events (webcasts and podcasts)
The tutorials below walk through making an application including inheritance, custom events and custom controls, object serialization and more.
Quick and easy custom events
Bulding an application - Part 1
Building an application - Part 2
Separating data from GUI - PLUS - serializing the data to XML
WPF version (WPF-MVVM data binding)
Passing values between forms/classes
Decouple your multi-threaded work from the GUI so forms don't hang

Working with environmental variables
'Why do we use delegates?' thread
And everyone always wants to connect to a database, right out of the gate so Database tutorials right here on DIC

C# Cookbooks
Are a great place to get good code, broken down by need, written by coding professionals. You can use the code as-is, but take the time to actually study it. These professionals write in a certain style for a reason developed by years of experience and heartache.

Everyone:
Debugging tutorial
Debugging tips
Debugging in detail
Great debugging tips
It still doesn't work, article

I urge you to work through the C# learning series here on DIC, and to work a self-teaching book from cover to cover before you even think about designing your own applications.
Microsoft Visual Studio Tips, 251 ways to improve your productivity, Microsoft press, ISBN 0-7356-2640-5 Has many, many great, real-world tips that I use all the time.

These are just good every-day references to put in your bookmarks.

Windows Presentation Foundation:
Create Animations Programmatically

Some of my common tips (some may apply more than others to your specific style):

• You have to program as if everything breaks, nothing works, the cyberworld is not perfect, the attached hardware is flakey, the network is slow and unreliable, the harddrive is about to fail, every method will return an error and every user will do their best to break your software. Confirm everything. Range check every value. Make no assumptions or presumptions.
  
  
• Take the extra 3 seconds to rename your controls each time you drag them onto a form. The default names of button1, button2... button54 aren't very helpful. If you rename them right away to something like btnOk, btnCancel, btnSend etc. it helps tremendously when you make the methods for them because they are named after the button by the designer.btnSend_Click(object sender, eventargs e) is a lot easier to maintain than button1_click(object sender, eventargs e)
  
  
• You aren't paying for variable names by the byte. So instead of variables names of a, b, c go ahead and use meaningful names like index, timeOut, row, column and so on. You should avoid 'T' for the timer. Amongst other things 'T' is commonly used throughout C# for Type and this will lead to problems. There are naming guidelines you should follow so your code confirms to industry standards. It makes life much easier on everyone around you, including those of us here to help. If you start using the standards from the beginning you don't have to retrain yourself later.
  You might want to look at some of the naming guidelines. Its a lot easier to start with good habits than to break bad habits later and re-learn.
  
  
  • Guidelines for names
    
  • Naming guidelines
    
  • Design guidelines for classes
  
  
  
• Try to avoid having work actually take place in GUI control event handlers. It is better to have the GUI handler call other methods so those methods can be reused and make the code more readable. This is also how you can send parameters rather than use excessive global variables. Get in this habit even if you are using WinForms because WPF works a lot under the idea of "commands" and this will get you working towards that. Think of each gester, control click, menu option etc. as a command to do something such as a command to SAVE. It doesn't matter where the command comes from, all sources should point at the same target to do the actual saving.

  // All of this different triggering mechinisms call the same single [il]SavePreferences()[/il] method
  
  btnSave(object sender, eventargs e)
  {
      SavePreferences(preferencesPath);
  }
  
  <KeyboardShortcut control+s bound to save>
  <Touchscreen guesture swiping from lowerleft to upperright bound to save>
  
  SaveMenuItem(object sender, eventargs e)
  {
      SavePreferences(@"C:\prefs\test.txt");
  }
  
  SaveContextMenu(object sender, eventargs e)
  {
      SavePreferences();// No parameter method overload
  }
  
  FormMain_Closing(object sender, eventargs e)
  {
      if (IsDirty) SavePreferences();
  }
  

  
  
  
• Don't replace lines of code that don't work. Instead comment them out and put your new attempts below that. This will keep you from re-trying the same ideas over and over. Also, when you come back to us saying "I've tried this 100 different ways and still can't get it", we can actually see what you tried. So often a failed attempt is very very close and just needs a little nudge in the right direction. So if we can say "See what you did in attempt 3... blah blah" it helps a lot

• I strongly suggest installing VMware or some other virtualization technology on your development PC so you can create a couple virtual computers for testing. This would allow you to debug and test inside: WinXP32, XP64, Vista, Win7x32, Win7x64... etc. without having to actually have 5 physical PC's. Visual Studio will let you send the debug directly into one of these virtual machines so you can watch it operate, check its variables, see the crashes and so on just as if it were debugging on your real machine.

  dis not b d'hood dawg... You are sitting at a real keyboard with a real monitor, not a cell phone. You are not here texting your high school posse to come to your kegger after their shift at Taco Bell. You are here asking for help from senior coding professionals who graciously donate their valuable time to helping the next generation of coders with their chosen craft. Please try to show them, yourself and the industry some respect by writing at least at an eighth grade level. (IE: English not ebonics or SMS, real words, punctuation and so on). If you can't take your own problem/question seriously enough to write like an adult, then why would you expect anyone else to take it seriously?
  
  When you write a post you are presenting yourself. Your writing style is all you have to show others who you are and what you stand for. When I see posts filled with lack of capitalization, SMS text like 'Urself', lack of punctuation and so on; what I see is someone who just doesn't care to make even an eighth grade presentation of themselves. I also see that you feel we are not worth the effort. Posts that look like this show that you don't feel the person you are talking to is worth speaking to as an adult. If you show this level of contempt or apathy towards someone you are asking for help how can you expect to be taken seriously or expect to receive that expert's fullest attention and time to help you?
