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 OneLoneCoder.com + + Redistribution and use in source and binary forms, with or without + modification, are permitted provided that the following conditions + are met: + + 1.
