| OneLoneCoder Pixel Game Engine v2.08 |
| "What do you need? Pixels... Lots of Pixels..." - javidx9 |
+-------------------------------------------------------------+
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 -lpng YourSource.cpp -o YourProgName
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
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!
Thanks

+GetScreenPixelSize() - returns actual size in monitor pixels
+Pixel Cohesion Mode (flag in Construct()) - disallows arbitrary window scaling
+Working VSYNC in Windows windowed application - now much smoother
+Added string conversion for olc::vectors
+Added comparator operators for olc::vectors
+Added DestroyWindow() on windows platforms for serial PGE launches
+Added GetMousePos() to stop TarriestPython whinging
2.08: Fix SetScreenSize() aspect ratio pre-calculation
Fix DrawExplicitDecal() - stupid oversight with multiple decals
Disabled olc::Sprite copy constructor
+olc::Sprite Duplicate() - produces a new clone of the sprite
+olc::Sprite Duplicate(pos, size) - produces a new sprite from the region defined
+Unary operators for vectors
+More pedant mollification - Thanks TheLandfill
+ImageLoader modules - user selectable image handling core, gdi+, libpng, stb_image
+Mac Support via GLUT - thanks Mumflr!

~~~~~~~~~~~~~~~~~~~~
If the olcPixelGameEngine.h is called from several sources it can cause
multiple definitions of objects. To prevent this, ONLY ONE of the pathways
to including this file must have OLC_PGE_APPLICATION defined before it. This prevents
the definitions being duplicated.
If all else fails, create a file called "olcPixelGameEngine.cpp" with the following
two lines. Then you can just #include "olcPixelGameEngine.h" as normal without worrying
about defining things. Dont forget to include that cpp file as part of your build!
