Map
minecraft:filled_mapA map is an item that displays a top-down view of explored terrain. Holding an active map updates it in real time, showing the player's position, and it can be cloned at a cartography table, zoomed out up to four levels, locked to freeze its contents, or placed in an item frame for display.
FAQ
How do I create a usable map?
Craft 8 sheets of paper with a compass at a crafting table for an empty map that tracks position, or buy one from a cartographer villager for 7 emeralds, then hold and use it to start mapping the surrounding 128x128 block area.
Can multiple players share the same map?
Yes. Cloning a map at a cartography table copies everything explored so far, and newly explored areas afterward appear automatically on all cloned copies.
Do maps work properly in the Nether?
No. Maps show only a red-and-gray pattern in the Nether, and the player pointer spins rapidly instead of indicating direction, making them unreliable for navigation there.
How do I stop a map from updating further?
Combine the map with a glass pane at a cartography table to lock it, permanently preserving its current explored terrain even as the world around it changes.
