Air

Air is a block in the Mindustry environment system. It serves as the basic environmental tile representing empty space and is part of the game's world geometry rather than a player-constructed building or unit; as such, it has no production, input, output, or crafting properties and does not contain resources or active functionality. Air defines the default unobstructed terrain state used by movement, pathfinding, and other systems that distinguish buildable or occupied tiles from empty background.
