World Map Command

Registers the command that opens the full-screen map.

Field	What it does
commandName	The command name, without the leading slash.
permission	Required to run it. Leave empty to allow everyone.

The world map shows what the player has explored, one cell per chunk. A chunk never visited is absent rather than empty — the two look different on purpose, so a player can tell an unexplored area from a genuinely empty one.

Opening the map suspends the HUD and the minimap, which would otherwise draw over it.
