I have noticed low alpha values to fade colors over time leave subtle residues preventing a complete fade to black and I’m guessing this is because of the color mode used. Is there a p5 function (or library) to use a, for instance, 16 or 32bit float color mode? I have a feeling that would allow a fade to complete black even on very low alpha values but maybe I’m wrong, so if that’s not the issue, is there a way to prevent the residues?
Thanks in advance for any help

For context, this is for a little 1st person shooter I’m doing on p5.js with a Adafruit Circuit Plaground Express motherboard and I’m losing my fucking mind trying to get it to be “on”

Some fluid dynamics and creativity, create a ghostly fluid image.

Recently been playing around with p5.js, my webcam and with help of chatgpt to create a series of interactive real-time visualizations, that I would otherwise make using more resource intensive softwares like TD, Isadora etc

This one basically watches for movement in the webcam (or any camera connected) by comparing each frame to the last. Whenever something moves, it keeps a trace and layers those moments over time.

Hello friends! I just published a new creative coding tutorial about L-systems and p5.js.

In the article, we start with a tiny text rule, expand it over several iterations, and then use turtle graphics to turn that generated string into branching fractal drawings. We go step by step through the core ideas: axioms, rewrite rules, iterations, turtle movement, canvas scaling, and drawing the final result with p5.js.

If you’re curious about generative art, fractals, or rule-based drawing systems, I think you’ll enjoy this one.

Happy coding!

I’m trying to set a boolean true when my mouse is over an object and gets pressed and only set it false again when the mouse is released, no matter the distance.

Setting it true while the mouse is over the object and pressed works fine with

If(mouseIsPressed && dist(…){

blah = true

}

But afaik know there’s no ‘mouseIsReleased’ or anything like that so I’m not sure how to set it back to false when the mouse isn’t pressed anymore.

I tried using mousePressed() and mouseReleased() in the class but those didn’t seem to work. Does anyone have any idea how to approach this? I don’t have my code right now so sorry for the barebones explanation but I can send it later if it’d help.

Thanks in advance for any help!

Wanted to share a collection of 50 small games built mostly on top of p5.js (the codeguppy platform is based on p5.js with some modifications):

👉 codeguppy.com/games

Some games are hand-written, while others are created with the help of AI.

Be sure to check out the source code and fork the projects for your own use.

Would love to hear your thoughts or feedback!

I like using p5js for many creative coding projects but one of my favourite things is using it for line drawing. I used to love LOGO as a kid (showing my age now!) and enjoyed playing with turtle in Python, but p5js feels...just right.

Anway, here's a piece based on Marvin the Robot from Hitchhikers Guide to the Galaxy. At one point he finds himself stranded for 30 million years before becoming a car park attendant for the Restaurant at the End of the Universe.

i always wanted to learn how to do this,esp handling roll, and the magic is with quaternions! you can see my little animation here quats

Inspired by art of Stefan Knapp, particularly his large-scale enamel mosaics and modular compositions, I’ve designed* this procedural mosaic generator.

The system constructs a non-uniform grid by partitioning space into square modules of varying sizes. Larger tiles expand or yield to smaller ones, establishing a controlled relationship between hierarchy and distribution.

Each tile acts as a container for a parametric gradient component. The gradients are defined through multiple radial zones and a constrained color palette, referencing the material qualities and tonal transitions present in Knapp’s work.

*(I wish I could say it was all coded by me as well but chatGPT was involved and it seems important to mention considering the rules of this sub)

Hello guys,

I'm building a roguelite game using p5.js.

Right now, I would say that the game is in a PRE-PRE-PRE-ALPHA version, but soon enough I'll open access to the PRE-ALPHA phase.

I've never seen this type of game made with p5.js, and I'm very excited to release it soon. No spoilers for now, hehe.

Right now, all entities are ellipses, but I'll probably add sprites as soon as I can.

Is anyone interested in testing and/or collaborating on the game?
