I've been meaning to implement this classic demo effect for years. Thanks to PICO-8 (which I've only just discovered!) I finally got around to it.</p> <p>I created a continuous wrap around palette from the seven rainbow colours so I can cycle the palette continuously. I implemented these as sprites so I didn't have to mess around dithering, etc in the code.</p> <p>Thanks to <a href="https://www.lexaloffle.com/bbs/?uid=556"> @rez</a> for idea of each &quot;pixel&quot; being a 2x2 image.</p> <p>Loads of room for improvement, but I'm pretty happy with this as a first attempt.</p> https://www.lexaloffle.com/bbs/?tid=34309 https://www.lexaloffle.com/bbs/?tid=34309 Wed, 22 May 2019 23:15:37 UTC
