still dose not work properly in browser DOWNLOAD FOR IT TO WORK! this will generate a random line of varying roughness, then adds in blocks around it. it does take quite a long time to run the later stages. it works by drawing a straight line and then cutting it in half, and changing the new two points, and then cuts them in half etc. then it fills in the blocks. Then it puts in trees, different for each of the three biomes. Then clouds appear (not in deserts). After it has finished doing all of this, steve appears! he can place blocks, delete blocks and move around. it does take 0.3 seconds to delete a block and will not delete if you change blocks, so stay on the same one. You can now place blocks and i am planning to make a survival mode in version 2, with crafting and new blocks!
