# Examples
Every now and then I sit down and try out some features of some library, C++ itself or with SFML.
Instead of letting those code fragments go to waste somewhere on my disk or get lost in the depth
of the SFML forum, I decided to put them openly and centralized here on GitHub for everyone to see,
share and learn from them.
Keep in mind that the code is provided as-is and isn't necessarily suited for your final product,
as not a lot of thought was put into performance or code design.
## zlib
### [gzip Decompression](https://github.com/eXpl0it3r/Examples/blob/master/zlib/GzipDecompression.cpp)
zlib is a small and useful library which allows the compression and decompression of data.
By applying some settings it's possible to let zlib decompress a gzip file, which this examples
demonstrates by loading a file into memory and output the decompressed data to standard output.
## SFML
### [Center Text](https://github.com/eXpl0it3r/Examples/blob/master/SFML/CenterText.cpp)
One of the most common questions you'll run into on the SFML forum is how to center a `sf::Text`
object inside a shape, or more commonly, a button. Because `sf::Text` aligns itself to the baseline
instead of the visual top/bottom, it tends to be more confusing that working with shapes and
sprites. In order to get it working properly, you have to take into account the `LocalBounds` as
is shown in the given example.
### [Fading Dots](https://github.com/eXpl0it3r/Examples/blob/master/SFML/FadingDots.cpp)
This was originally created as a test for [this thread](https://en.sfml-dev.org/forums/index.php?topic=9350.0)
(or was it [this one](https://en.sfml-dev.org/forums/index.php?topic=9139.0)?), but since I kind of
liked the result I adjusted a few things and uploaded it.
### [Flashlight](https://github.com/eXpl0it3r/Examples/blob/master/SFML/Flashlight.cpp)
Out of nowhere came suddenly all those requests (starting with [this one](https://en.sfml-dev.org/forums/index.php?topic=9210.0))
for subjective blending and I think, I could help a few people with my example on how to achieve
what they wanted.
 
### [Hue Shift](https://github.com/eXpl0it3r/Examples/blob/master/SFML/HueShift.cpp)
Although I can't find the original SFML thread about this, I found the
[StackOverflow question](https://stackoverflow.com/questions/11458552/cycle-r-g-b-vales-as-hue/)
which was IIRC created before the forum thread. This effect can definitely give a nice ambiance,
but it probably could need some retouching. Since the picture do not tell much: Starting off with
one color the example automatically iterates through the whole RGB color spectrum in a smooth way.
### [Lightning](https://github.com/eXpl0it3r/Examples/tree/master/SFML/Lightning)
I had once read a tutorial in connection with SFML on how to create some nice 'laser' effect.
Unfortunately I don't remember which blog/site this was on, because he was using some texture
moving which made everything look even better. While doing a search to possible find that tutorial
again, I found another similar piece of code [on the forum](https://en.sfml-dev.org/forums/index.php?topic=3189.0),
adapted it for SFML 2 and made a nicer class out of it.
### [Mixing SoundBuffers](https://github.com/eXpl0it3r/Examples/blob/master/SFML/MixingSoundBuffers.cpp)
The other day in #learnprogramming on freenode someone was trying to implement a way to mix two
audio files without actually playing them back. I wondered how something like that would work with
SFML and thus went ahead an wrote a small example. A quick Google search on audio sample mixing
brought me to [this site](https://atastypixel.com/how-to-mix-audio-samples-properly-on-ios/)
and lead me to the current implementation.
### [Road](https://github.com/eXpl0it3r/Examples/blob/master/SFML/Road.cpp)
I'm not sure if there ever existed a forum post or if the whole conversation happened on IRC,
but someone wanted to make a 'scrolling' road and since I really liked that idea, I went ahead
and implemented an example. The code here is particularly not that nice, so keep that in mind
when adapting it.
### [Rotating Triangle](https://github.com/eXpl0it3r/Examples/blob/master/SFML/RotatingTriangle.cpp)
One of the age old questions by game development beginners is along the lines of "How do I rotate
my player to face X?". This short example answers that question, by rotating a triangle
(`sf::CircleShape` with three points) to wherever the mouse pointer is on the window.
### [Rotating Vertices](https://github.com/eXpl0it3r/Examples/blob/master/SFML/RotatingVertices.cpp)
This example answers the same question as the 'Rotating Triangle' one, but it uses a `sf::VertexArray`
in combination with a `sf::Transformable`. It's a good foundation to see how one could start to
implement an entity class deriving from `sf::Transformable` and `sf::Drawable`.
### [Simple AABB](https://github.com/eXpl0it3r/Examples/blob/master/SFML/SimpleAABB.cpp)
Every month there's at least one question on simple collision detection testing the last 'bigger'
one with in [this forum thread](https://en.sfml-dev.org/forums/index.php?topic=9352.0), which
lead to this example. I've even implemented some _very_ simple physics, which will fail in most
situations, but you can at least move around and jump.
### [Sound Recording](https://github.com/eXpl0it3r/Examples/blob/master/SFML/SoundRecording.cpp)
Even though SFML has a [tutorial](https://www.sfml-dev.org/tutorials/2.5/audio-recording.php)
and an [example](https://github.com/SFML/SFML/tree/master/examples/sound_capture) on sound
recording, I wanted to have my own small demonstration of said feature with recording device
selection and mono/stereo options.
