<li>Each layer consists of many '''tiles''', which are 16×16 pixel squares placed in a grid to form the visible map. Each tile can have properties (e.g. passable / blocked), special logic (e.g. an action to perform when the player steps on them), and a picture to show. The picture is represented by a sprite index (or tile index), which is its position in an associated spritesheet (see next).</li> | <li>Each layer consists of many '''tiles''', which are 16×16 pixel squares placed in a grid to form the visible map.
