make sure background color change happens in #?????? format, not the 0x?????? format
User prompt
every few ticks, change background color to a new tint close to the current background color
User prompt
tint each star with a random bright color
User prompt
sounds good, please do that.

create a textlabel in center of screen with the text "Captain, please confirm order to keep accellerating. We are approaching very dangerous speeds. And where the HELL are we actually going?"

nice, but no movement sensed

ok, sounds good, please do that.

please use this logic to implement similar functionality using KL engine: "let outerspace = document.querySelector("#outerspace"); let mainContext = outerspace.getContext('2d'); let canvasWidth = outerspace.width; let canvasHeight = outerspace.height; let centerX = canvasWidth * 0.5; let centerY = canvasHeight * 0.5; let numberOfStars = 500; let stars = []; let frames_per_second = 60; let interval = Math.floor(1000 / frames_per_second); let startTime = performance.now(); let previousTime = startTime; let currentTime = 0; let deltaTime = 0; class Star { constructor() { this.x = getRandomInt(-centerX, centerX); this.y = getRandomInt(-centerY, centerY); this.counter = getRandomInt(1, canvasWidth); this.radiusMax = 1 + Math.random() * 10; this.speed = getRandomInt(1, 5); this.context = mainContext; } drawStar() { this.counter -= this.speed; if (this.counter < 1) { this.counter = canvasWidth; this.x = getRandomInt(-centerX, centerX); this.y = getRandomInt(-centerY, centerY); this.radiusMax = getRandomInt(1, 10); this.speed = getRandomInt(1, 5); } let xRatio = this.x / this.counter; let yRatio = this.y / this.counter; let starX = remap(xRatio, 0, 1, 0, canvasWidth); let starY = remap(yRatio, 0, 1, 0, canvasHeight); this.radius = remap(this.counter, 0, canvasWidth, this.radiusMax, 0); mainContext.beginPath(); mainContext.arc(starX, starY, this.radius, 0, Math.PI * 2, false); mainContext.closePath(); mainContext.fillStyle = "#FFF"; mainContext.fill(); } } function setup() { for (let i = 0; i < numberOfStars; i++) { let star = new Star(); stars.push(star); } } setup(); function draw(timestamp) { currentTime = timestamp; deltaTime = currentTime - previousTime; if (deltaTime > interval) { previousTime = currentTime - (deltaTime % interval); mainContext.clearRect(0, 0, canvasWidth, canvasHeight); mainContext.fillStyle = "#111"; mainContext.fillRect(0, 0, canvasWidth, canvasHeight); mainContext.translate(centerX, centerY); for (let i = 0; i < stars.length; i++) { let star = stars[i]; star.drawStar(); } mainContext.translate(-centerX, -centerY); } requestAnimationFrame(draw); } draw();"
User prompt
methodically go through these steps and carefully examine each part of the game's logic related to star movement and initialization. It should be possible to identify the root cause of the issue and implement a solution that results in the stars moving as intended across the game screen.
User prompt
carefully examine those areas to identify and correct the issues.
User prompt
sounds like some solid fixes. please apply them.
User prompt
fix it also by preventing very small z values
User prompt
please fix this using cap on maximum speed
User prompt
please ensure the spawning and initialization logic for the stars uses a truly uniform distribution method that takes into account the entire screen area.

something wrong with the scaling
User prompt
create a realistic 3d starfield effect with movement

when stars move offscreen, respawn them with new random position and initial values

User prompt
please implement it then
User prompt
Please fix the bug: 'ReferenceError: scaleFactor is not defined' in or related to this line: 'star.vx = dx * star.speed * scaleFactor;' Line Number: 86
User prompt
stars should speed up as they approach screen edges
