Mini-map
From Wikipedia, the free encyclopedia
A mini-map is a miniature map, often placed in a corner of the screen in computer games to aid in reorientation. Mini-maps usually display traversable terrain, allies, enemies, and important locations or items.

[edit] Usage of GPS
Often, the mini-map is aided by a GPS in order to dynamically update the current position of the player with respect to the surrounding environment, in which case the view would resemble that of a radar screen. Mini-maps have become almost standard-issue in RTS and MMORPG genres, as a notion of where the current screen lies within the scope of the game world is necessary.
[edit] Dynamic discovery
In most games, the mini-map begins as a solid field of black, and the map is automatically drawn as the player discovers new areas of the game world.
[edit] Layers
Similar to custom layers in Google Earth, some team-oriented multi-player games, such as Age of Empires II or Empire Earth, allow players to draw temporary lines, signals or markings on the mini-map for others to see. Things in a fog of war portion of a mini-map may not be updated until they are rediscovered.
