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. + + +License (OLC-3) +~~~~~~~~~~~~~~~ + +Copyright 2018 - 2022 OneLoneCoder.com + +Redistribution and use in source and binary forms, with or without modification, +are permitted provided that the following conditions are met: + +1.

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 + + + +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.
