Let's start by creating the particles for the jelly cube and connecting them with constraints to give it that jelly-like behavior.\n\nWe'll create a grid of particles, and then we'll use constraints to connect these particles together. This will help simulate the elasticity of a jelly-like structure. Here's how we can do it:\n\n### Step 1: Create Particles\nWe will create a grid of particles to represent the structure of the jelly cube. Each particle will be a physics body.\n\n### Step 2: Add Constraints\nWe will add constraints between the particles to simulate the connections that give the jelly cube its structure and elasticity.\n\nLet's start by adding the code to create the particles and constraints for the jelly cube.\n\n```javascript\n// script.js\nfunction createJellyCube() {\n let cols = 5; // Number of columns\n let rows = 5; // Number of rows\n let spacing = 40; // Spacing between particles\n\n for (let i = 0; i < cols; i++) {\n for (let j = 0; j < rows; j++) {\n let x = width / 2 + i * spacing;\n let y = height / 2 + j * spacing;\n let particle = Bodies.circle(x, y, 10, { restitution: 0.5 });\n particles.push(particle);\n World.add(world, particle);\n }\n }\n\n // Add constraints between particles\n for (let i = 0; i < cols - 1; i++) {\n for (let j = 0; j < rows - 1; j++) {\n let p1 = particles[i + j * cols];\n let p2 = particles[i + 1 + j * cols];\n let p3 = particles[i + (j + 1) * cols];\n\n let constraint1 = Constraint.create({\n bodyA: p1,\n bodyB: p2,\n stiffness: 0.2,\n length: spacing\n });\n let constraint2 = Constraint.create({\n bodyA: p1,\n bodyB: p3,\n stiffness: 0.2,\n length: spacing\n });\n\n constraints.push(constraint1, constraint2);\n World.add(world, [constraint1, constraint2]);\n }\n }\n}\n```\n\n- **Particles**: We create a grid of particles, each represented as a circle using Matter.js `Bodies.circle`.\n- **Constraints**: We connect adjacent particles using `Constraint.create` to simulate the jelly-like behavior.\n\nNow let's add the code to display these particles and constraints in the `displayParticles` and `displayConstraints` functions.\n\n```javascript\n// script.js\nfunction displayParticles() {\n fill(255, 0, 0);\n noStroke();\n for (let particle of particles) {\n let pos = particle.position;\n ellipse(pos.x, pos.y, 20, 20);\n }\n}\n```\n\n```javascript\n// script.js\nfunction displayConstraints() {\n stroke(0);\n for (let constraint of constraints) {\n let posA = constraint.bodyA.position;\n let posB = constraint.bodyB.position;\n line(posA.x, posA.y, posB.x, posB.y);\n }\n}\n```\n\n- **Display Particles**: We draw each particle as a red circle.\n- **Display Constraints**: We draw lines between connected particles to visualize the constraints.\n\nWith these changes, you should have a jelly-like structure that responds to physics and looks like a grid of connected particles.

Additionally, we can allow interaction by enabling mouse dragging on the particles, so you can grab and move them.\n\n### Step 1: Add a Floor\nWe will create a static rectangle that represents the floor.\n\n### Step 2: Enable Interaction\nWe'll add mouse interaction to allow you to drag the particles around.\n\nLet's start with adding the floor first.

Here’s how to implement that:\n\n1. Use `mousePressed` to detect when the mouse is pressed.\n2. Use `mouseDragged` to move the particle if it's being dragged.\n3. Use `mouseReleased` to stop dragging.\n\nHere's how you can implement it:\n\n```javascript\n// script.js\nlet selectedParticle = null; // To keep track of the particle being dragged\n\nfunction mousePressed() {\n for (let particle of particles) {\n let pos = particle.position;\n let d = dist(mouseX, mouseY, pos.x, pos.y);\n // Check if the mouse is close to the particle\n if (d < 20) { // 20 is the diameter of the particle\n selectedParticle = particle; // Select the particle\n break;\n }\n }\n}\n\nfunction mouseDragged() {\n if (selectedParticle) {\n // Move the selected particle to the mouse position\n Body.setPosition(selectedParticle, { x: mouseX, y: mouseY });\n }\n}\n\nfunction mouseReleased() {\n selectedParticle = null; // Release the particle\n}\n```\n\n### Summary of Changes:\n- **Floor**: A static rectangle is created and added to the world to serve as the ground.\n- **Interaction**: Functions are added to allow you to click and drag the particles.\n\nWith these updates, your jelly cube should now rest on a floor and allow you to interact with it by dragging the particles around.
