=============== The Recipe File =============== The `tiles.rc' file is the recipe file for generating the tiles. It is a plain-text file, where each line begins with a tile id, followed by an image specification. The image specification consists of one or more image layers separated by the pipe character (|). The layers are drawn in the order specified. A layer is a file name (excluding the .png extension), optionally followed by @X,Y, where X,Y specify the upper-left corner of the rectangle to draw. ============================== Generating the composite image ============================== To build a new tiles.png file, do the following: 1. Open a command-prompt, and cd to the micropolis-java directory. 2. Build Micropolis by typing the following command: ant 3. The generated tiles.png file can be found in the build/ subdirectory. 4. Now you can run Micropolis with the new graphics. Type: java -jar micropolisj.jar
