Tile set

A tile set is collection of smaller images called tiles (typically of uniform size) which have been combined into a single larger image. Tile sets are often used in 2D video games to create complex maps from reusable tiles within the set. When a tile set based map is displayed, the tiles that are stored within it are used to reassemble the map for display. This technique is seen in games designed to run on portable systems such as Nintendo's Game Boy Advance system or a cellular phone. Using tile sets reduces the amount of system memory required to display maps since it allows for the same tiles to be reused multiple times in a map. It also reduces amount of artwork needed for individual maps since many different ones can be created from the same tileset. In order for maps made from tile sets to appear more distinctive, games typically display them with a different tile set for each unique environment.

This method is implemented in many 2D games as well as applications meant for game creation such as Game Maker and Tiled.
