Auto-tiling is an experimental feature available in the Map Editor that can serve as a time saver when laying out certain types of terrain in your map. It provides a quick and efficient way of placing sets of tiles that border each other, for example land and water, by automatically taking care of adjacent edge tiles and corner tiles.

Each tileset used for auto-tiling will consists of 16 different tiles. This set will satisfy every possible border between the two terrain types. In many cases, like the land and water example shown below, the corner and edge tiles can be simply be rotated in order to complete the required tileset.

To create an auto-tile configuration for your game, first create a new blank map. Then, starting at coordinate (0, 0, 0), place the 16 tiles for your tileset in a horizontal row toward the right, ending at coordinate (15, 0, 0). You can include multiple tilesets in your configuration. For example, the second tileset would go from coordinate (0, 1, 0) to (15, 1, 0).
