Here's tutorial for libSDL2pp, C++11 bindings/wrapper for SDL2. It covers core functionality of the library, including initialization and window construction, loading image files, sprite and text rendering, animation, and event handling trying to demonstate library features in as little code as possible.
The tutorial is split into lessons, which demonstrate gradual development of a simple application resembling a platformer game.
- lesson00: SDL library initialization, window creation, image loading and rendering
- lesson01: picking specific sprite from an image atlas
- lesson02: main loop, event processing
- lesson03: timing and animation
- lesson04: keyboard control
- lesson05: texture generation
- lesson06: alpha blending and color modulation
- lesson07: text rendering
Each lesson adds some lines to the code and, thus, functionality
to the application. You can explore these lessons sequentially
starting from the first one (in which you might find e.g. git diff lesson00.cc lesson01.cc helpful to see what was added by
the next lesson), or just jump straight to the last one and see
all bits at once.
To build executables from these lessons, you need cmake, SDL2, SDL2_image and SDL2_ttf libraries and corresponding development files.
To build the tutorial, run
cmake . && make
which will produce a set of binaries: lesson00 .. lesson07.
