here we go again..

the p5files e2024 001

minimalistic fxhash and p5.js template

rgb pixel drawing and mixing engine - the sketch.js code is 156+ lines

opensource. free source, learning source. on my part. get your engines runnin =_______= in p5js

be respectful to the creators p5.js and ppl that helped you out

some nice juicy coding parts . to enjoy. xxx amsterdam - `don't worry I do the marketing`

all about the pixel rgb buffer this weekend// under- heavy construction =_____= elout 2.xxx

w.i.p - more updates soon. need to add some more code blocks

still tuning, and checkn

check the latest hopeful running version on p5js - enjoy.

https://editor.p5js.org/elout/sketches/4VZHZnysf

latest fullscreen 'stand-alone' version runs at. still updates and lil fixes.

//!!!! 
// fxhash changed the fxhash.js

// they will using now fxhash.min.js
// get it here

// love y'all (inc. those degens. for the entertainment value) =_______=


// .--------------.
// .fix/speed upgrade - jan26.2024 
// speed upgrade you can draw/update things at  different fps speeds, to gain speed
// you could draw different things at different  fps speeds or slows

//worked till the early morning light
//and dropped it on today on fxhash. started to enjoy  the weekend agaim. just now

//https://www.fxhash.xyz/generative/30097

//I put it onchain, it showed/costed me about 0.75 gas?! cost? to mint, 
// and directly running source from the chain, so pretty nice if you can do that, and not so expensive to do
// so total mint cost, to mint this project;  was like less 1tez? pretty cool and ok


//[got some warnings about the fxhash.js not being latest.. when uploading to fxhash this morning 
//it can show red sometimes, then go green after a few minute. peace out]

// local backup should include these files:

// index.html
// fxhash.js
// p5.min.js
// style.css
// sketch.js

// getting you p5  ready for fxhash and running local in a browser +fullscreen


// local backup should include these files:

// fxhash.js
// p5.min.js
// style.css
// sketch.js

// check if it runs local /offline

// sketch.js does the drawing and painting


// ----------about index.html---------------

// links to the  libraries, sketches and parts. etc!!

// don't use external links (url's)  to libraries that can change, store the root and running local
// and try to use latest 'n og' downloaded versions from legit libraries

// best using and waving with the latest released legit libs and versions
// although things will sure change in the future.. 
// i just try to get it  running on ok and current and new versions, make them a bit flexible
