Let's start by adding the particle system and the sliders for controlling the properties of the smoke and fire particles. \n\nWe'll implement the following features:\n\n1. **Particle Class**: To represent individual particles.\n2. **Particle System**: To manage multiple particles.\n3. **Sliders**: For controlling particle size, speed, and lifespan.\n\n### Step 1: Create the Particle Class\n\nWe'll start by creating the `Particle` class that will handle the behavior of individual particles.\n\n```javascript\n// script.js\nclass Particle {\n constructor(x, y) {\n this.position = createVector(x, y);\n this.velocity = createVector(random(-1, 1), random(-3, -1)); // Upward movement\n this.lifespan = 255; // Initial lifespan\n this.size = random(5, 15); // Random size for each particle\n }\n\n update() {\n this.position.add(this.velocity); // Move the particle\n this.lifespan -= 2; // Decrease lifespan over time\n }\n\n display() {\n stroke(0, this.lifespan); // Stroke color based on lifespan\n strokeWeight(this.size); // Particle size\n point(this.position.x, this.position.y); // Draw the particle\n }\n\n isDead() {\n return this.lifespan < 0; // Check if the particle is dead\n }\n}\n```\n\n### Step 2: Create the Particle System\n\nNext, we'll create a simple particle system to manage multiple particles.\n\n```javascript\n// script.js\nlet particles = []; // Array to hold particles\n\nfunction setup() {\n createCanvas(windowWidth, windowHeight);\n background(135, 206, 235); // Sky blue background\n}\n\nfunction draw() {\n background(135, 206, 235); // Clear the background\n if (frameCount % 5 === 0) { // Create a new particle every few frames\n particles.push(new Particle(width / 2, height)); // Start from the bottom center\n }\n\n // Update and display each particle\n for (let i = particles.length - 1; i >= 0; i--) {\n particles[i].update();\n particles[i].display();\n if (particles[i].isDead()) {\n particles.splice(i, 1); // Remove dead particles\n }\n }\n}\n```\n\n### Step 3: Add Sliders for Particle Properties\n\nFinally, we'll add sliders to control the particle size, speed, and lifespan. You can add this HTML code to your `index.html` file to create the sliders.\n\n```html\n\n\n \n Particle Size\n \n Particle Speed\n \n Particle Lifespan\n \n\n```\n\n### Step 4: Update Particle Class to Use Sliders\n\nNow we will update the `Particle` class to use the values from the sliders.\n\n```javascript\n// script.js\nclass Particle {\n constructor(x, y) {\n this.position = createVector(x, y);\n this.velocity = createVector(random(-1, 1), random(-speedSlider.value(), -1)); // Upward movement based on speed slider\n this.lifespan = lifespanSlider.value(); // Lifespan based on lifespan slider\n this.size = random(sizeSlider.value() - 10, sizeSlider.value()); // Size based on size slider\n }\n}\n```\n\n### Summary\n\n1. We created the `Particle` class to manage individual particle behaviors.\n2. We created a particle system to manage multiple particles.\n3. We added sliders in the HTML to control particle properties.\n\nYou can now modify your `script.js` and `index.html` files with the provided code.

Here are some ideas to achieve that:\n\n1. **Vary Particle Size**: Instead of using a fixed size from the size slider, we can add some randomness to the size within a certain range.\n\n2. **Randomize Velocity**: We can give the particles a wider range of velocities to create more variation in their movement.\n\n3. **Color Variation**: We can add some color variation to the particles to simulate different types of smoke and fire.\n\n### Step 1: Update Particle Class for Size and Velocity Variation\n\nLet's modify the `Particle` class to include these variations:\n\n```javascript\n// script.js\nclass Particle {\n constructor(x, y) {\n this.position = createVector(x, y);\n // Randomize the vertical velocity more significantly\n this.velocity = createVector(random(-1, 1), random(-speedSlider.value, -speedSlider.value - 2)); // Upward movement based on speed slider\n this.lifespan = lifespanSlider.value; // Lifespan based on lifespan slider\n // Randomize size more\n this.size = random(sizeSlider.value - 10, sizeSlider.value + 10); // Size based on size slider with variation\n this.color = color(255, 165, 0, this.lifespan); // Orange color for fire effect\n }\n\n update() {\n this.position.add(this.velocity); // Move the particle\n this.lifespan -= 2; // Decrease lifespan over time\n }\n\n display() {\n stroke(this.color); // Stroke color based on lifespan\n strokeWeight(this.size); // Particle size\n point(this.position.x, this.position.y); // Draw the particle\n }\n\n isDead() {\n return this.lifespan < 0; // Check if the particle is dead\n }\n}\n```\n\n### Step 2: Adjust the Draw Function\n\nYou might want to also add some randomness in how the particles are created. For example, you could modify the horizontal position slightly each time a new particle is created. \n\nHere’s an example of how to do this in your `draw` function:\n\n```javascript\n// script.js\nfunction draw() {\n background(135, 206, 235); // Clear the background\n if (frameCount % 5 === 0) { // Create new particles every few frames\n for (let i = 0; i < amountSlider.value; i++) { // Use the amount slider value\n // Randomize the horizontal position slightly\n let xOffset = random(-20, 20); // Slight horizontal offset\n particles.push(new Particle(width / 2 + xOffset, height)); // Start from the bottom center\n }\n }\n\n // Update and display each particle\n for (let i = particles.length - 1; i >= 0; i--) {\n particles[i].update();\n particles[i].display();\n if (particles[i].isDead()) {\n particles.splice(i, 1); // Remove dead particles\n }\n }\n}\n```\n\n### Summary of Changes\n\n1. **Size Variation**: Added more randomness to the particle size.\n2. **Velocity Variation**: Increased the range of vertical velocity for particles.\n3. **Color**: Defined a color for the particles to simulate fire.\n4. **Horizontal Offset**: Randomized the horizontal position of new particles.\n\n### Next Steps\n\nPlease update your `Particle` class and `draw` function with the provided code.
