Изучил уже до ООП, вопрос что делать дальше? Могу ли я уже писать программы, с чего начинать?

8Observer8,

I get error, when use command on terminal

fatal: not a git repository (or any of the parent directories): .git

@8Observer8 · 06.01.2019, 12:20

You must run the commands in the folder: "Snake2D_FreeGlutOpenGL11Cpp" which you cloned earlier from https://github.com/8Observer8/... penGL11Cpp

You will see the git repository (.git folder) in the folder "Snake2D_FreeGlutOpenGL11Cpp".

@8Observer8 · 11.01.2019, 23:36

I think it is very important to study math for computer graphics. Video tutorial series: Math for Game Developers

P.S. If you cannot study this tutorial now then save it in your bookmarks.

@8Observer8 · 12.01.2019, 18:19

What is wrong if I just select "Release" and click "Build"?

Thank you, maybe it will be useful in the future. I did not have problems with building from VS before.

All required dlls we copy automatically from the local Libs folder to the Release folder using these "Post-Build Event" commands:

xcopy /y /d "$(ProjectDir)Libs\freeglut-3.0.0-2\lib\Win32\freeglut.dll" "$(OutDir)"
xcopy /y /d "$(ProjectDir)Libs\irrKlang-1.6.0\lib\Win32\irrKlang.dll" "$(OutDir)"
xcopy /y /d "$(ProjectDir)Libs\irrKlang-1.6.0\lib\Win32\ikpMP3.dll" "$(OutDir)"
xcopy /y /d /i /e "$(ProjectDir)Audio" "$(OutDir)\Audio"

I built to a release (x86) of CyberGame's version. Please, try to run it for a test: SnakeByCyberGame.zip

@8Observer8 · 14.01.2019, 13:18

CyberGame, if you do not have time to making the tasks then study this book: Getting Things Done: The Art Of Stress Free Productivity. It will help you to impove your productivity. And learn blind ten-finger (touch-typing) technique with the training: "SOLO: Touch Typing Tutor" in English

Study this book: Professional C++, 2nd Edition
Especially study the code from the book: Download Code

I like 2nd Edition more than 3rd Edition (or 4th) because 2nd Edition have additional materials like "Design Patterns". You can make this book your handbook.

Game Development with OpenGL/GLSL is one of the best way to study programming, math and physics. It is very fun, interesting and cognitive. See this video and feel how it fun: Math for Game Developers - Jumping and Gravity (Time Delta, Game Loop)

I think that one of the best way is studying OpenGL/C++ through WebGL/JavaScript. It is more simple way. It is better to use TypeScript instead JavaScript but it is more complicated. You can make examples in WebGL and translate them to C++/OpenGL. WebGL examples and simple games with be available in all platforms in one click without compilation for all platforms and without downloading and installing.

You can place you examples in the Internet in the Playgrounds like: jsfiddle.com, plnkr.co, codepen.io and so on. Everyone can run, see a code, and edit the code. You can place your games in your website.

See how to draw a square and move it with WASD and Arrow Keys. It is enough from WebGL to make the Snake Game.

Playground: https://jsfiddle.net/tqnfyy53/

You can ask me what you do not understand. I can explaid you every single line. I can to write commentaries.

Что изучать для совершенствования знаний по C++

I think, you should not be limited with learning of C++. Try to learn: C#, Python, JavaScript, TypeScript and so on. It is very useful. In this case you can choose which tool is better for your current task. For example, you can learn C++ by creating a simple clone game, for example, Battle City. I think you do not know the Battle City game bacause you too young. You are 15 years old only. If you want to make an application with GUI it is simpler to use C# + WinForms (or WPF; I use WPF because I think it is better).

If you study a several languages these languages with help you to study programming in general. You can apply general knowledges from one project to another, from one book to another, from one tutorial to another and so on.

For example, If you study game development with OpenGL you can use tutorials about OpenGL in several languages. This is the legendary video course about OpenGL + Java: OpenGL 3D Game Tutorial created by guy with nickname ThinMatrix. You can translated the code to C++, C#, JavaScript/WebGL and so on.

I recommend you to complete this very simple text tutorial: Python Snake Game (OpenGL). I think it is useful to study Python with OpenGL by creating simple games.

I don't can read book on english language.

"I ~~don't~~ can" --> "I cannot read"

Why? I think you didn't try it yet. You can chose another book if this book is difficult for you.

This quote is from "Professional C++":

The Obligatory Hello, World

In all its glory, the following code is the simplest C++ program you’re likely to encounter:

C++
1
2
3
4
5
6
7
// helloworld.cpp
#include <iostream>
int main()
{
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

This code, as you might expect, prints the message “Hello, World!” on the screen. It is a simple
program and unlikely to win any awards, but it does exhibit the following important concepts about
the format of a C++ program.

What is difficult to understand here?

If you don't know words like "unlikely" or "awards" you can use a dictionary. I like "Collins COBUILD Dictionary on CD-ROM 2006". It is very simple dictionary for beginners. You can find simple description and examples.

For example, let's find the word "unlikely":

If you say that something is unlikely to happen or unlikely to be true, you believe that it will not happen or that it is not true, although you are not completely sure.
A military coup seems unlikely...
As with many technological revolutions, you are unlikely to be aware of it...
It's now unlikely that future parliaments will bring back the death penalty...
In the unlikely event of anybody phoning, could you just scribble a message down?

8Observer8, You understand, what if i was every word found in vocabulary. I will lose meaning

@COKPOWEHEU · 22.01.2019, 14:59

You can write your translation word-by-word like auto-translator. Then you read the text and rewrite it according to Russian language.

Then you read the text and rewrite it according to Russian language.

I use another way when I translate from English. I translate from English to English (not to Russian). I use Monolingual Dictionaries. This technic is very popular. It means you need to forget Russian. You should to kill Russian translator in yourself. I use Russian only when I need to translate unknown word from Russian to English.

When you say "an apple" you should to imagine an apple. You shouldn't translate it to Russian. At the first time it is very difficult but it become more and more simple with time.

For example, you need to understand the word "hello":

1. You say 'Hello' to someone when you meet them.
Hello, Trish...
Do you want to pop your head in and say hallo to my girlfriend?

2. You say 'Hello' to someone at the beginning of a telephone conversation, either when you answer the phone or before you give your name or say why you are phoning.
A moment later, Cohen picked up the phone. 'Hello?'

3. You can call 'hello' to attract someone's attention.
Very softly, she called out: `Hallo? Who's there?'

You can see transcription and listen how to say this word:

It is only at the beginning. You will remember vocabulary in the process naturally. Documentation is your main friend. But documentation is in English only. It is better if you will study C++ in English. In any case, you will study C++ very slowly because it is very difficult language. English will not slow you down very soon. It is very important You will study it all your life. It is better to learn through making simple games and simple game engines using OpenGL and GLSL. But making simple games is not simple. You need to work very hard and spend a lot of time to it.
