Start with this simple code and build on it to make a cool rain animation.</p> <ol class="styled-list"> <li>Add more drops to the arrays. You can do that by using a <code>for</code> loop and <code>random()</code> function at the beginning of the program, or using an array modification method during animation. You could even add more drops in response to user interaction. <li>Make the rain continuous by changing the position of each drop when it reaches one side of the canvas, using a conditional or <a href="/cs/the-operator/6698198968041472" target="_blank">% operator</a>. <li>Bonus: Make an array of colors, so that every drop is a different color, or an array of speeds. <li>Bonus: Make other things rain, like snowflakes (using more shape commands) or avatars (using the image commands). If you use multiple commands to draw whatever is raining down, consider creating a custom function with parameters instead. </ol> project
