We'll give the stars random starting positions and velocities.\n\n```javascript\nclass Star {\n constructor() {\n this.x = random(-width, width);\n this.y = random(-height, height);\n this.z = random(width);\n this.pz = this.z;\n }\n\n update() {\n this.z = this.z - speed;\n if (this.z < 1) {\n this.z = width;\n this.x = random(-width, width);\n this.y = random(-height, height);\n this.pz = this.z;\n }\n }\n\n show() {\n fill(255);\n noStroke();\n\n let sx = map(this.x / this.z, 0, 1, 0, width);\n let sy = map(this.y / this.z, 0, 1, 0, height);\n\n let r = map(this.z, 0, width, 16, 0);\n ellipse(sx, sy, r, r);\n\n let px = map(this.x / this.pz, 0, 1, 0, width);\n let py = map(this.y / this.pz, 0, 1, 0, height);\n\n this.pz = this.z;\n\n stroke(255);\n line(px, py, sx, sy);\n }\n}\n```\n\n- The constructor sets the initial position of the star (this.x, this.y) randomly within the canvas. It also sets a random z value, which we'll use to give the effect of depth (this.z). The pz variable (previous z) is used to create a trail effect for the stars.\n- The update function moves the star closer to the observer by decreasing its z value. If the star has moved past the observer (z < 1), it resets the star's position and z value.\n- The show function draws the star. We use the map function to convert the star's position from 3D space to 2D space. We also use map to calculate the radius of the star, making it appear larger as it gets closer. Finally, we draw a line from the star's previous position to its current position, giving the illusion of motion.","project_id":327,"created_at":"2024-01-11T02:17:14.244018Z","output_tokens":null,"code_id":18884,"input_tokens":null,"id":11862},{"deleted":0,"sender":"human","message":"how do i draw them","project_id":327,"created_at":"2024-01-11T02:18:03.261175Z","output_tokens":null,"code_id":18886,"input_tokens":null,"id":11863},{"deleted":0,"sender":"ai","message":"To draw the stars, we first need to create an array of Star objects.

Each star is given random x, y, and z values.\n- The draw function is a p5.js function that gets called continuously, 60 times a second by default. This is where we'll perform the animation.\n- We first clear the canvas with `background(0)`. Then we translate the origin (0, 0) to the center of the canvas. This is because by default, the origin in p5.js is in the top left corner, but for this project, it's more intuitive to have the origin in the center.\n- We then loop through the stars array and call each star's update and show methods. The update method moves the star closer to the observer, and the show method draws the star on the canvas.
