What are the Minecraft gamemodes?
Gamemodes are, as the name suggests, different modes that you can play Minecraft in, altering the player’s abilities and how they interact with the game world. Changing your game mode can also adjust how the game looks and how creatures in the world react to you.
You can set the Minecraft gamemode during world creation.
You can also change the gamemode during play by typing in the games text chat. Some examples are below;
/gamemode adventure
/gamemode creative
/gamemode survival
Note: To change gamemode during play on multiplayer worlds, the player needs to have the “Operator” permission level.
