Code	/*I know many other people have made land generators similar to this one, but I decided to make my own. Other than the base code from the "noise" documentation, I made this program from scratch. Change the two variables below to customize your world, or, paste a seed you liked into the seed variable and make a spin-off so others can see the world. * Click the screen to see the seed * Please leave problems or suggestions in the tips and thanks. * * * Thanks to Bruce for correcting a mistake that made spin-off seeds not work. * https://www.khanacademy.org/profile/brew/ * * Thanks to questinmcquilkin for the idea of gradient water. * https://www.khanacademy.org/profile/testtube24/discussion * * Thanks to GatlingPea64 for the spin-off of relistic colors: https://www.khanacademy.org/profile/kaid_247058220845920746191354/projects * * Thanks to 𝓐𝓆𝓊𝒶𝓞𝓇𝒸𝒽𝒿𝒹 for the suggestion of more realistic coloring: https://www.khanacademy.org/profile/AquaOrchid/ * * * Thanks to all those who voted up my program! It was so cool being in the first row of the hot list! I nearly jumped up and down with excitement seeing it so high! Again, thanks everyone!! :D * * My favorite seed is -2262. */ //The smoothness of the land.
