Firstly, I need to - maintain several different versions of it to accommodate users on Windows7, - 8, 10, Linux, Mac, Visual Studio & Code::Blocks. Secondly, this year I've been - pushing the console to the limits of its graphical capabilities and the effect - is becoming underwhelming. The engine itself is not slow at all, but the process - that Windows uses to draw the command prompt to the screen is, and worse still, - it's dynamic based upon the variation of character colours and glyphs. Sadly - I have no control over this, and recent videos that are extremely graphical - (for a command prompt :P ) have been dipping to unacceptable framerates. As - the channel has been popular with aspiring game developers, I'm concerned that - the visual appeal of the command prompt is perhaps limited to us oldies, and I - dont want to alienate younger learners. Finally, I'd like to demonstrate many - more algorithms and image processing that exist in the graphical domain, for - which the console is insufficient. - - For this reason, I have created olcPixelGameEngine! The look and feel to the - programmer is almost identical, so all of my existing code from the videos is - easily portable, and the programmer uses this file in exactly the same way. But - I've decided that rather than just build a command prompt emulator, that I - would at least harness some modern(ish) portable technologies. - - As a result, the olcPixelGameEngine supports 32-bit colour, is written in a - cross-platform style, uses modern(ish) C++ conventions and most importantly, - renders much much faster. I will use this version when my applications are - predominantly graphics based, but use the console version when they are - predominantly text based - Don't worry, loads more command prompt silliness to - come yet, but evolution is important!! - - License (OLC-3) - ~~~~~~~~~~~~~~~ - - Copyright 2018 - 2019 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, so google this. You will also need to enable C++14 - in your build options, and add to your linker the following libraries: - user32 gdi32 opengl32 gdiplus - - Ports - ~~~~~ - olc::PixelGameEngine has been ported and tested with varying degrees of - success to: WinXP, Win7, Win8, Win10, Various Linux, Rapberry Pi, - Chromebook, Playstation Portable (PSP) and Nintendo Switch.
