In this tutorial, as I promised we start to make the sidscroller (platform) game in SDL with C++.
It's my longest tutorial (it's 18 part long).
SDL is a cross-platform free-source library which allows you to draw to the screen (so make graphical programs), we'll make 2D games with it, but it can make 3D render as well, if you use it with OpenGL.
