What is this?
~~~~~~~~~~~~~
olc::PixelGameEngine is a single file, cross platform graphics and userinput
framework used for games, visualisations, algorithm exploration and learning.
It was developed by YouTuber "javidx9" as an assistive tool for many of his
videos. The goal of this project is to provide high speed graphics with
minimal project setup complexity, to encourage new programmers, younger people,
and anyone else that wants to make fun things.
However, olc::PixelGameEngine is not a toy! It is a powerful and fast utility
capable of delivering high resolution, high speed, high quality applications
which behave the same way regardless of the operating system or platform.
This file provides the core utility set of the olc::PixelGameEngine, including
window creation, keyboard/mouse input, main game thread, timing, pixel drawing
routines, image/sprite loading and drawing routines, and a bunch of utility
types to make rapid development of games/visualisations possible.

Compiling in Linux
~~~~~~~~~~~~~~~~~~
You will need a modern C++ compiler, so update yours!
To compile use the command:
g++ -o YourProgName YourSource.cpp -lX11 -lGL -lpthread -lpng -lstdc++fs -std=c++17
On some Linux configurations, the frame rate is locked to the refresh
rate of the monitor. This engine tries to unlock it but may not be
able to, in which case try launching your program like this:
vblank_mode=0 ./YourProgName
Compiling in Code::Blocks on Windows
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Well I wont judge you, but make sure your Code::Blocks installation
is really up to date - you may even consider updating your C++ toolchain
to use MinGW32-W64.
Guide for installing recent GCC for Windows:
https://www.msys2.org/
Guide for configuring code::blocks:
https://solarianprogrammer.com/2019/11/05/install-gcc-windows/
https://solarianprogrammer.com/2019/11/16/install-codeblocks-gcc-windows-build-c-cpp-fortran-programs/
Add these libraries to "Linker Options":
user32 gdi32 opengl32 gdiplus Shlwapi dwmapi stdc++fs
Set these compiler options: -std=c++17
Compiling on Mac - EXPERIMENTAL! PROBABLY HAS BUGS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Yes yes, people use Macs for C++ programming! Who knew? Anyway, enough
arguing, thanks to Mumflr the PGE is now supported on Mac. Now I know nothing
about Mac, so if you need support, I suggest checking out the instructions
here: https://github.com/MumflrFumperdink/olcPGEMac
clang++ -arch x86_64 -std=c++17 -mmacosx-version-min=10.15 -Wall -framework OpenGL
-framework GLUT -framework Carbon -lpng YourSource.cpp -o YourProgName
Compiling with Emscripten (New & Experimental)
~~~~~~~~~~~~~~~~~~~~~~~~~
Emscripten compiler will turn your awesome C++ PixelGameEngine project into WASM!
This means you can run your application in teh browser, great for distributing
and submission in to jams and things! It's a bit new at the moment.
em++ -std=c++17 -O2 -s ALLOW_MEMORY_GROWTH=1 -s MAX_WEBGL_VERSION=2 -s MIN_WEBGL_VERSION=2 -s USE_LIBPNG=1 ./YourSource.cpp -o pge.html
PGE update for emscripten comand.

em++ -std=c++17 -O2 -s ALLOW_MEMORY_GROWTH=1 -s MAX_WEBGL_VERSION=2 -s MIN_WEBGL_VERSION=2 -s USE_LIBPNG=1 $(Get-ChildItem *.cpp) -o pge.html --preload-file assets

Using stb_image.h
~~~~~~~~~~~~~~~~~
The PGE will load png images by default (with help from libpng on non-windows systems).
However, the excellent "stb_image.h" can be used instead, supporting a variety of
image formats, and has no library dependence - something we like at OLC studios ;)
To use stb_image.h, make sure it's in your code base, and simply:
#define OLC_IMAGE_STB
Before including the olcPixelGameEngine.h header file. stb_image.h works on many systems
and can be downloaded here: https://github.com/nothings/stb/blob/master/stb_image.h
Multiple cpp file projects?
~~~~~~~~~~~~~~~~~~~~~~~~~~~
As a single header solution, the OLC_PGE_APPLICATION definition is used to
insert the engine implementation at a project location of your choosing.
The simplest way to setup multifile projects is to create a file called
"olcPixelGameEngine.cpp" which includes the following:
#define OLC_PGE_APPLICATION
#include "olcPixelGameEngine.h"
That's all it should include. You can also include PGEX includes and
defines in here too. With this in place, you dont need to
#define OLC_PGE_APPLICATION anywhere, and can simply include this
header file as an when you need to.
Ports
~~~~~
olc::PixelGameEngine has been ported and tested with varying degrees of
success to: WinXP, Win7, Win8, Win10, Various Linux, Raspberry Pi,
Chromebook, Playstation Portable (PSP) and Nintendo Switch. If you are
interested in the details of these ports, come and visit the Discord!
