Project to quickly get something working in p5.js and typescript
This is based on the Regular Polygon sketch available in the p5js examples
git clone https://github.com/Gaweph/p5-typescript-starter.git
npm i
npm start
A local version will now be running on localhost:3000
P5 is able to run in either global or instanced mode. https://github.com/processing/p5.js/wiki/Global-and-instance-mode
This starter project now uses Global mode to bring it inline with most of the online resources provided by the project.
As stated on the P5 wiki:
While this is convenient (and friendlier) it's important to note that this can lead to problems and confusion down the road when mixing other JS libraries or trying to embed multiple p5 sketches on the same page. A safer, more advanced methodology is to create a p5 sketch as an object "instance".
The following examples are both functionaly the same.
let x = 100;
let y = 100;
function setup() {
createCanvas(windowWidth, windowHeight);
}
function draw() {
background(0);
fill(255);
rect(x, y, 50, 50);
}
var sketch = (p: p5) => {
this.x = 100;
this.y = 100;
p.setup = () => {
p.createCanvas(p.windowWidth, p.windowHeight);
};
p.draw = () => {
p.background(0);
p.fill(255);
p.rect(this.x, this.y, 50, 50);
};
};
new p5(sketch);
This starter project will work with either mode, feel free to experiment with both.
