NAME
flipflop - draws a grid of 3D squares that change positions
SYNOPSIS
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]
DESCRIPTION
Flipflop draws a grid of 3D colored tiles that change positions with each other.
OPTIONS
-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.
-window Draw on a newly-created window. This is the default.
-root 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.
-wireframe
Only draw outlines.
-texture | -no-texture
Whether to texture the tiles with a screen grab or an image.
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.
