5.3.7 Tile Maps

- -

A tile map is a scene created by composing lots of small sprites, -called “tiles”, into a larger image. One program for editing such -maps is called Tiled. Chickadee has native -support for loading and rendering Tiled maps in the (chickadee -graphics tile-map) module. -

Procedure: load-tile-map file-name [#:chunk-size]: Load the Tiled formatted map in file-name and return a new tile -map object. -

- -

Procedure: tile-map? obj: Return #t if obj is a tile map. -

- -

Procedure: tile-map-orientation tile-map: Return the orientation of tile-map. -

- -

Procedure: tile-map-width tile-map: Return the width of tile-map in tiles. -

- -

Procedure: tile-map-height tile-map: Return the height of tile-map in tiles. -

- -

Procedure: tile-map-tile-width tile-map: Return the width of tiles in tile-map. -

- -

Procedure: tile-map-tile-height tile-map: Return the height of tiles in tile-map. -

- -

Procedure: point->tile tile-map x y: Translate the pixel coordinates (x, y) into tile -coordinates. -

- -

Procedure: draw-tile-map tile-map [#:layers] [#:camera] [#:origin] [#:position] [#:scale] [#:rotation] [#:blend-mode] [#:tint] [#:time]: -
Draw the layers of tile-map as viewed from camera, a 2D -vector offset. By default, all layers are drawn. To draw a subset of -the available layers, pass a list of layer ids using the layers -keyword argument. -
