- [Instructor] As I mentioned in the previous video,…JavaScript doesn't have a built-in noise function.…We need to find it from somewhere else.…Luckily, JavaScript has a huge ecosystem…of third-party libraries.…Here is one library that implements…a Perlin noise function in JavaScript.…You can check out the GitHub page for this library…and understand how it works…and download the library from there.…I already downloaded this file,…and it's included in the lib folder of the project files.…If you have been following along,…you can copy and paste or enter this line…into your HTML file.…
We can call the Perlin noise function…with the following commands and use it…instead of the sine function.…So instead of using the sine function here,…I can call the command called simplex2,…which will call the Perlin noise function.…The simplex2 function takes two arguments,…two continuous values,…so instead of having this as a single argument,…I'm going to be passing it two times,…so to be able to do that I will save…this value inside a variable.…
