Instance mode : accessing `p5` functions in an external class

[GoToLoop]

@sylcha

… where I would like to use p5 functionalities,

Request a p5 object as 1 of the constructor’s parameters:

@sylcha

class Chiffre {
  constructor(x, y, signe, p = p5.instance) {
    this.p = p;
    this.signe = signe;
    this.position = p.createVector(x, y);
    this.vitesse = p.createVector();
    this.acceleration = p.createVector();
  }
}

And pass it when instantiating the class:

@sylcha

import { Chiffre } from "./Chiffre.js";

export const sketch = s => {
  s.chiffre = new Chiffre(20, 20, '2', s);
};

The code above should work if that parameter s happens to be of datatype p5.

For more examples of classes which also request a p5 object take a look at the sketch below:

Converting coding challenge 'Self-avoiding walk backtracing' from p5.js to Processing (Java)

I’m back w/ another “Self Avoiding Walk II” conversion. This time I’m using the CoffeeScript language which directly transpiles to JavaScript. Processing 2 used to have a CoffeeScript Mode a long time ago and I’ve ended up learning it. When I later decided to learn Python Mode to help folks here I’ve relied on my previous CoffeeScript knowledge b/c they have similar syntax. The old CoffeeScript Mode relied on the Pjs library in order to run its transpiled sketch on the web. Which by the way is …
