XScreenSaver !!!XScreenSaver NAME SYNOPSIS DESCRIPTION OPTIONS BUGS ENVIRONMENT SEE ALSO COPYRIGHT AUTHOR(s) ---- !!NAME maze - an automated X11 demo repeatedly creating and solving a random maze !!SYNOPSIS __maze__ [[-display ''host:display.screen''] [[-foreground ''color''] [[-background ''color''] [[-window] [[-root] [[-install] [[-visual ''visual''] [[-grid-size ''pixels''] [[-live-color ''color''] [[-dead-color ''color''] [[-solve-delay ''usecs''] [[-pre-delay ''usecs''] [[-post-delay ''usecs''] [[-generator ''integer''] [[-max-length ''integer''] [[-bridge] [[-no-bridge] !!DESCRIPTION The ''maze'' program creates a '' !!OPTIONS ''maze'' accepts the following options: __-window__ Draw on a newly-created window. This is the default. __-root__ Draw on the root window. __-install__ Install a private colormap for the window. __-visual__ ''visual'' Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. __-grid-size__ ''pixels'' The size of each block of the maze, in pixels; default is 0, meaning pick a random grid size. __-live-color__ ''color'' The color of the path. __-dead-color__ ''color'' The color of the failed path (it is also stippled with a 50% pattern.) __-skip-color__ ''color'' The maze solver will choose to not go down a path if it can __-surround-color__ ''color'' If the maze solver ever completely encloses an area within the maze, then it knows that the exit is not in there (and in fact the interior of that area might not even be reachable.) It will mark out those cells using this color. __-solve-delay__ ''integer'' Delay (in microseconds) between each step of the solution path. Default 5000, or about 1/200th second. __-pre-delay__ ''integer'' Delay (in microseconds) between generating a maze and starting to solve it. Default 2000000 (2 seconds.) __-post-delay__ ''integer'' Delay (in microseconds) after solving a maze and before generating a new one. Default 4000000 (4 seconds.) __-generator__ ''num'' Sets the algorithm that will be used to generate the mazes. The default is -1, which randomly selects an algorithm for each maze that is generated. Generator 0 is the original one, and works by walking around randomly until we hit a place we've been before, then backtracking and trying a new direction somewhere. Generator 1 picks a random spot in the maze, then draws a straight wall from that spot in a random direction until it hits another wall (and continues until the maze is complete). Generator 2 is based on sets. Initially all cells are in different sets. Then two neighboring cells are chosen and if they are in different sets, their sets are joined. If they were in the same set, a wall is built between them. This continues until the maze is complete. All generators generate mazes with a certain 'characteristic'. See if you can spot them! __-max-length__ ''num'' Controls the maximum length of walls drawn in one go by generator 1. __-bridge__ __-no-bridge__ Controls whether or not a 'bridge' will appear over the logo. Clicking the mouse in the maze window controls it. __!LeftButton__ Clears the window and restarts maze. __!MiddleButton__ Pause or unpause the program. __!RightButton__ Exit. !!BUGS Expose events force a restart of maze. Mouse actions are based on !!ENVIRONMENT __DISPLAY__ to get the default host and display number. __XENVIRONMENT__ to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. !!SEE ALSO X(1), xscreensaver(1) !!COPYRIGHT Copyright 1988 by Sun Microsystems, Inc.
