The word AFK stands for Away From Keyboard. We call something AFK that is away from the keyboard. For example in messaging programs, or chats if somebody is AFK that means that the user is in the program, but he or she is not at his or her computer.
In Minecraft we can take advantage of players who are AFK to build automatic farms. In this case the player needs to stand somewhere still, or use a macro to preform automatic actions. This is good, because while the player is not playing, their account farms automatically, and when the player returns to play, he or she farmed lots of resources already.
Types of AFK farms Edit
- Spawner XP farms (dungeons, silverfish spawners, blaze spawners) - the spawner will only spawn mobs if a player is in range, that's why it isn't enough to keep the chunk loaded.
- Mob farms - The player needs to be in a perfect range for mobs to keep spawning, but not respawning, that's why it isn't enough to keep the chunk loaded.
- Left or right click farms - The player needs to constantly left or right click while the farms is running and he or she is AFK. This is needed for some farms for actions that redstone can't perform, for example placing blocks (e.g. saplings in a tree farm). The constant left or right clicking can be preformed with macros, or if you consider macros a bit cheaty, there is an alternative solution: when you're in Minecraft, press the buttons which you want to be constantly triggered while you're AFK, hold them, and press F11, and while it is turning to full screen, but it isn't done yet, release the buttons. Now you can just press the Windows Key on Windows / Home (Not the home key close to the num pad, but the key which is instead of the Windows Key) on Linux / Command on Mac to go out to another application, but if you do this make sure that you have pressed F3+P in Minecraft before pressing F11 so when going to another application Minecraft won't show up the pause screen.
