An MCFUNCTION file contains commands used in Minecraft, an open-ended block construction game. It stores a list of one or more commands that can be executed in the game to perform actions, such as teleporting a player or moving blocks.

MCFUNCTION files were first supported by version 1.12 of Minecraft. They store commands in plain text with each command placed on a separate line. You can view and edit the contents of an MCFUNCTION file with a text editor. MCFUNCTION files should be placed in the following directory in order to be executed within the game: .minecraft/saves/[WORLD_NAME]/data/functions/ NOTE: In order to use MCFUNCTION files in Mojang Minecraft in Android and iOS, Experimental Gameplay must be enabled.
