draws a grid of 3D squares that change positions


flipflop [-display host:display.screen] [-visual visual] [-window] [-count number | -free number] [-size number] [-size-x number] [-size-y number] [-spin number] [-mode sticks | tiles] [-delay number] [-wireframe] [-fps] [-texture]


Flipflop draws a grid of 3D colored tiles that change positions with  each other.


-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.


Draw on a newly-created window.  This is the default.


Draw on the root window.

-count number

Number of tiles on the board. A value of "0" means "default". The default number of tiles depends on the size of the board and the mode: 95% of total tiles for "tiles" mode and 80% of total sticks for "sticks" mode (e.g. 76 tiles or 64 sticks for a 9x9 board).

-free number

Number of tiles missing from the board. See -count.

-size number

Number of tiles on each side of the board. Takes precedence over -size-x and -size-y. Default: 9.

-size-x number

Width (in tiles) of the board. Default: 9.

-size-y number

Length (in tiles) of the board. Default: 9.

-spin number

Angular velocity for the rotation of the board.

-mode sticks

Draw hopping sticks instead of flipping tiles.

-mode tiles

Draw flipping tiles. This is the default.

-delay number

Per-frame delay, in microseconds.  Default: 20000 (0.02 seconds.).

-fps | -no-fps

Display the current frame rate, CPU load, and polygon count.


Only draw outlines.

-texture | -no-texture

Whether to texture the tiles with a screen grab or an image.



to get the default host and display number.


to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
