Pre-generate Minecraft 1.12 world chunks while AFK - get rid of block lag!

This is a Minecraft 1.12 update for my previous 1.9 contraption, which could be found here: https://www.youtube.com/watch?v=7WSMgOVsnCU I show a vanilla Minecraft 1.12 command block which can _pre-generate_ a Minecraft world, so that when you play, you get less block lag! Background: The Minecraft terrain generator is one of the more computationally expensive parts of the game, so when starting a new world, or exploring out into new chunks, you may find that the game 'lags' because Minecraft is computing the new chunks. Thus I created a way to generate all those chunks before you start (while you're AFK - "away from keyboard"), so that once you're ready to actually play, things run smoothly. To use this one-command-block contraption, create a new world in creative mode, and then /tp 0 250 0 /give @p command_block Right-click the command block, paste in the command copied from here: https://pastebin.com/y7UHeu4x Set the command block to 'always active' Set your render distance to 8 chunks /scoreboard players set @a Running 1 Wait (go AFK) for 'RadiusCompletedSoFar' to reach the desired size /scoreboard players set @a Running 0 Set your render distance back to whatever size you like And now you're ready for a Minecraft experience with less lag! If you waited until the radius reached '1000' (which might take 15 minutes), then all the chunks from -1000,-1000 to +1000,+1000 will have been generated. Note that this will change the spawn point of the world. If you want to use this in an _existing_ world, be sure to write down the coordinates of the existing spawn point, so you can teleport back there and set it back with /setworldspawn after running the AFK-pre-generator.
