" > invalid arrows which turn blocks into

Presumably that's the same phenomenon as above, with one
arrow to put static
nasty and another to put
background? "
yes. with a bit of fine-tuning this
allows you to create
moving-platforms,
moving-holes-in-the-ground, moving-nasty-blocks, floors
with
moving-nasty-patches on them, platforms which are snatched from under
your
feet, and platforms which suddenly appear to help you.
(all of which appear
in WGDTB. i call it 'invalid
arrow technology' :)
lots of possibilities and
permutations. the only drawback is that the arrows
required
look rather odd in a lot of cases (some in WGDTB look
like
bell-bars being hurled across the screen :). oh and of
course you *have* to
have the arrows accompanying the
effect...
" I presume you're alluding to ramps with Offset
218 = 255. It was John
Elliott who first posted
about them here. "
i'm not sure i get this whole
218 = 255 thing ?:)?. i was referring to ramps
with
a value other than 0 or 1. they have some very
strange effects, including
one room with square
staircases like in C64 JSW! (and yes, they 'feel'
square
as well as 'look' square !)
" If `earth' is
your term for `wall', then We Pretty ("DIA MOND B O Z
Y").
Stay men, nearby. We must caress SU's Mr. Dykes.
"
silly of me to miss that. it's interesting how they can
be solid but 'a
ramp' at the same time,
though.
" The arrows must also collide with black ink
pixels (but the colour they
appear as (still white?)
"
yes, the arrows are still white with the
patch.
" > invalid ramp air - chaos :)
I take it
that's not just the springy platforms seen in We Pretty
and
JSW(again)? (background colour = ramp colour) "
well,
same principle, but the ramp is invalid, and the
results are *much*
more voletile. i recommend people
try it - it opens up a whole new can of
worms as
far as quirky features goes! (heard of the expression
- "everything
you know is wrong!"? :).
as
there are 254 invalid values, there is also plenty of
room for
experimentation, although most of the
values seem to give tediously similar
variations on a
theme.

That sounds
very clever. I'm not really familiar with diagonal
guardians
(JSW128 diagonal guardians, I take it, rather than Geoff
Mode diagonal
guardians). "
yes, it's
JSW128. there appears to be differences between the two
modes when
it comes to diagonals. when they wrap
around (in JSW128), they write colours
to the top of
the screen. looks rather messy, but i've grown
disinterested
in 'neatness'. i've also abused guardians in some
other ways but i don't
want to give too much away
:)
the interesting thing about discovering quirky
features is the increasing
possibilities for combining
them all into more complex situations.
it's
probably limitless, and it forces you to see beyond the '4
block types, ramp
and a conveyor' of it all and
really get those grey cells moving!
