Why do we use SDL with C & C++?

In this video you will learn why we choose to include and use the SDL library in our C & C++ projects.
Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by games, video playback software, emulators, and many other applications including several AAA titles.
SDL officially supports Windows, Mac OS X, Linux, iOS, and Android (other supported platforms may be found in the source code).
SDL is written in C, works natively with C++, and there are bindings available for several other languages, including C# and Python. It is the most popular platform for multi-plarform game development.
One of the great aspects of using SDL in gamedev projects is that SDL 2.0 is distributed under the zlib license, which allows you to use SDL freely in any software.
We will learn why we need to use SDL to guarantee that our projects are portable and run smoothly regardless of the operating system or machine that the students are running.

In a nutshell, SDL is essentially a GUI version of stdio.

Well, there you go! That saves16 minutes of everyone's lives. 😅

@user-wv5nl1wh6l 2 жыл бұрын

so maybe when we are making bigger projects we may need more powerful library/SDK like wxWidget, Qt, etc but we always learn stdio before iostream for better understanding of code.

Yeah basically. It used to be that the only form of output I could rely on was printf statements to see if my code was working. Now I have thousands of pixels in a window to tell me!

I have used Raylib, SDL, Allegro, and SFML in the past. They are all good. However one of the benefits of SDL seems to be the incredible speed at which it compiles and runs. It’s a smaller library and because it contains less, it can be easier to learn and debug. I like SDL for the same reason I like C. The simplicity.

@@CykPykMyk I chose SDL2 over Raylib. Main reason is that its “industry” standard for game dev. Unreal uses it as a base and even game maker. Other engines have also used it as a base. It has more platform support than Raylib such as Nintendo switch. All you need is a Nintendo dev account and you will get access to SDL2 version of Nintendo switch.

In short: SDL allows communication with OS through a unified interface that works across platforms - No need to write your app 3 times for windows, linux and mac.

Do you have a course that would apply to my desire to create (in C and SDL) a wireframe dungeon crawler similar to Akalabeth? I've never understood to do such a thing when everyone has different screen resolutions. In other attempts, I've done it by line drawing to fixed positions (like on an Apple II). Thanks for reading.

It is possible to get SDL working with msys2 on Windows to have a basic Linux compiling environment within Windows. That’s how I bypassed Visual Studio and could still compile SDL programs.

btw, in the 80ies or 90ies pixels or lines were drawn with commands in basic or pascal and not by poking.

These were simply high-level functions that were often implemented in direct assembly. The assembly still has to go and access the display XY values somehow.

What's the difference between sdl and libraries like opengl? Is it that opengl only handles graphics and sdl can handle sound graphics input etc?

@pikuma 9 ай бұрын

OpenGL is a graphics API that can communicate and abstract the GPU. So, if you want to draw polygons, 3D objects, use shaders, all this using the GPU, then you'll need OpenGL (or Direct3D, or Vulkan, etc.). SDL is smart enough to know if you have a GPU on your machine & OpenGL already installed, and SDL usually can use them behind the scenes for some sruff (like displaying a Window and some 2D graphics). I hope this helps. 😬

Your ideas seem to be a bit biased against Windows or Microsoft. As a former Unix dev, I do not see where the Windows Terminal is not as "powerful" as the Unix terminal. Could it be the lack of a package manager? Well, even you said that each Linux distro has a preferred one, probably because tar or cpio were never enough historically. In Windows you can use vcpkg and do the very same thing as you do with brew on MacOS. And be sure you can use the same line tools like make or CMake and keep your courses multi-platform and "modern", even on Windows.

@pikuma 2 жыл бұрын

Oh, don't get me wrong. I actually think Powershell is probably more powerful than bash or even zsh. For example, just the fact that I can import .net libraries and create a .net form via shell is amazing in my opinion. That's powerful! My mention of Windows and its command-line was basically that Windows is not a command-line focused OS. Most of what we do is via UI and I feel that is misleading to beginner programmers. It's nice to force students to touch the filesystem, and Linux is a good example of that.

@antoniodosreisfeitosaneto7553 2 жыл бұрын

@@pikuma :) Well, it is as misleading to beginner programmers at it is for someone that uses a Mac for a life without ever knowing about the existence of a thing like a terminal. The thing about Unix and derivatives is that, when it started life, programmers and non-programmers had the same interface. And it was a terminal. And it could be a tty one, with no fancy screen at all. It is the same for Windows, X-Windows and MacOS: people get "misleaded" by the UI. And can end up thinking that it is all that is. IDE included.
