By moving two sticks and the button, try to
make the fish swim in another direction.
This applet is capable of handling any number of
matches and buttons, and can be made any size. It is also possible to
specify a different matchstick length if necessary. The default length,
shown in the example, is 69 pixels. Any desired background color can be
specified. I'm using light gray here, to blend in with the rest of the page.
The applet will automatically select an appropriate shadow color.
The controls are relatively simple: buttons can be moved around. Matches
can be moved or rotated, depending on where you click. If you point at or
near the head or the other end, the match will be rotated. Otherwise it
will just be moved.
There is a special applet parameter called "snap", set to either "yes" or
"no", specifying whether a match should adjust its alignment when
dropped. When "snap" is turned on, a rotated match will come to rest at
a multiple of 15 degrees. This makes it easier to build squares and
triangles. A moved match will come to rest with its head or other
end "attached" to the head or other end of another match, if there is one
within a short distance.
|A different example, with just three sticks,
slightly longer, no button and no "snapping".
To clarify, "attached" matchsticks meet
at a point slightly outside their physical form, as shown in the picture
to the left. This is to ensure that there is enough room for several
matches to meet at any corner or junction. The same thing applies to the
Since this applet has been sold and I no longer own the rights to it, I
can't provide any downloadable version. I'm just displaying it here as
a source of inspiration to other Java developers.
