[-maxColors number] [-dropSpeed number] [-override]
DESCRIPTION
Creates a world of falling blocks that build up and up.
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.
-delay number
Per-frame delay, in microseconds. Default: 10000 (0.01 seconds.).
-wireframe | -no-wireframe
Render in wireframe instead of solid.
-fps Display the current frame rate, CPU load, and polygon count.
-size number
Size of the base/carpet.
-spawn number
Likeyhood of a new block being created per frame : 1 high, 1000 very low.
-camX number
Initial camera X location in the world.
-camY number
Initial camera Y location in the world.
-camZ number
Initial camera Z location in the world.
-rotate | -no-rotate
Add/Remove rotation to/from the animation.
-no-carpet
Remove the base/carpet.
-no-nipples
Remove nipples on the blocks (also applies to udders) (has no effect in blob mode).
-blob Run in blob mode, blocks become over sized spheres.
-rotateSpeed number
Varries speed of world rotation.
-follow Camera follows blocks as they fall instead of camera being semi static (stays with top block).
-maxFalling number
Maximum number of objects created before recycling occurs.
-resolution number
Resolution of tubes, disks and spheres.
-maxColors number
Number of different colors available to falling objects.
-dropSpeed number
Varries speed of falling objects.
-override
Overrides camera settings and provides a tunnel view.
KEYS
a Increases viewing X coordinate.
z Decreases viewing X coordinate.
s Increases viewing Y coordinate.
x Decreases viewing Y coordinate.
d Increases viewing Z coordinate.
c Decreases viewing Z coordinate.
f Increases camera location X coordinate.
v Decreases camera location X coordinate.
g Increases camera location Y coordinate.
b Decreases camera location Y coordinate.
h Increases camera location Z coordinate.
n Decreases camera location Z coordinate.
r Increases world rotation.
q quit.
EXAMPLES
To see which block follow-mode is tracking, set the number of block colors to 1.
topblock -follow -maxColors 1
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.
