​

For a more complex path following either I do it as an exercise (see explainations in the video from 12' to 15'30''). 

The solution made by Daniel Shiffman is here : https://editor.p5js.org/codingtrain/sketches/2FFzvxwVt

let vehicle ;

function setup() {

  createCanvas(800, 400);

  vehicle = new Vehicle( 100, 100 ) ;

  vehicle.vel.x = 2 ;

  path = new Path( 0, height/2, width, height/2 ) ;

}

​

function draw() {

  background(70);

  path.end.y = mouseY ;

  let force = vehicle.follow( path) ;

  vehicle.applyForce( force ) ;

  vehicle.edges() ;

  vehicle.update() ;

  vehicle.show() ;

  path.show() ;

}
