This is the + * documentation of the API used in the program to generate the effect. It should + * be fairly simple, but basically: + * + * class AASaver is the main class, which handles outside events. All of the + * processing happens in the Screen class however, which manages a list of + * Sprites, updating them and drawing them as needed. When AASaver receives a + * paintEvent(), it forwards it on to Screen to handle it. + * + * Each Sprite is composed of 1 or more Frames. When a Screen wants a Sprite + * to draw itself, the Sprite forwards the request to its currently shown Frame. + * + * The Frame is rectangular, and created from textual ASCII art, with a ASCII + * art shape and color mask. The mask is optional. See aasaver.cpp for + * examples for creating a Frame. + * + * The Frame supports transparency and colors, and will convert the textual data + * into a QPixmap representation on demand in order to reduce CPU load (at the + * expense of a slight memory usage increase for each sprite). + * + * Screen handles the timing for the project, and at each timeout will call + * Sprite::tickUpdate() from Screen::doAnimate(). + * + * This whole program was inspired/copied from Kirk Baucom's asciiquarium + * program, from http://www.robobunny.com/projects/asciiquarium/ + */ + +/** + * The main class for the Asciiquarium screensaver. + */ +class AASaver: public KScreenSaver +{ + /// Handles the animation and drawing. + Screen* screen; + +public: + /// Construct the screensaver with window id \p id. + AASaver( WId id ); + + /// Returns a random double between [0.0, limit). + static double doubleRand(double limit) + { + return (limit * (static_cast<double>(KApplication::random()) / RAND_MAX)); + } + + /// Returns a random integer between [0, limit) + static int intRand(int limit) + { + return KApplication::random() % limit; + } + + /** + * Returns a QString holding a color mask, created by choosing random colors + * to replace numbers in \p color_mask. + */ + static QString randColor(QString color_mask); + + /// Adds the castle sprite to the screen. + void addCastle(); + + /// Adds the environment (sea, etc.) to the screen. + void addEnvironment(); + + /// Adds the seaweed to the screen. + void addAllSeaweed(); + + /// Adds the initial layout of fish to the sea, scaling the number of fish + /// based on the current screen size. + void addAllFish(); + + /** + * Adds a seaweed to a random position of the sea bottom. + * + * @param screen The Screen to add into. + */ + static void addSeaweed(Screen* screen); + + /** + * Returns a new fish sprite, which has not yet been added to a screen. + * + * @param screen The Screen to use when constructing the Sprite. + * @todo Combine with addFish(). + */ + static Sprite *newFish(Screen *screen); + + /** + * Adds a new fish sprite to \p screen. + * + * @param screen The Screen to add a fish to. + */ + static void addFish(Screen *screen); + + /** + * Adds a new air bubble sprite to \p screen.
