Draw a green ball that bounces around the canvas.

Run the Simulation on P5.js Editor

  x += vx;

  // Check for collision with the canvas edges and reverse velocity if needed
  if (x + radius > width || x - radius < 0) {
    vx *= -1; // Reverse x velocity
  }

    vy *= -1; // Reverse y velocity
  }

  // Draw the ball
  fill('green');
  ellipse(x, y, radius * 2, radius * 2);
