Code	/ Welcome to Terragen - My attempt at a Random Terrain Generator! Grass, dirt, stone, ores, caves, magma, sand, water, trees, clouds and flowers are all generated to form a pleasant-looking terrain. And, come on... of course I'm gonna let you play around with it! To change the time of day, use the right and left arrow keys, or press space to make time pass automatically. To change the current biome, press the B key. To change the weather, press the W key. Other changes can be made by changing the following variables: Line 11 - Steepness, Line 17 - Frequency of Ores/Flowers, Line 20 - World Size, Line 22 - Number of "Cave Generators", Line 25 - Average size of Caves, Line 28 - Cloud Frequency, Line 30 - Tree Frequency, Line 31 - Sea Level, Line 32 - Average Tree Height / //THE CHANGELOG IS NOW AVAILABLE AT "https://www.khanacademy.org/computer-programming/terragen-official-changelog/4947706835042304".
