Hi,
The new fl-leaves look very nice. I have never been fond of the old ones
that show up the grid boundaries where nothing should be visible.
I'm glad you like it. I may still make a tiny little change to it...
there's one area where I can just barely see a line, and where the
pattern
looks a little too repetitive. But I think there are plenty of other
things
to work on first.
One of you mentioned that some items don't have their shadows. Can
you tell
me which items you're referring to?
I referred to items like it-bag, it-surprise, it-string (that orange
trefoil).
Sure, items that can't be picked up (for example it-magnet) don't
require a shadow.
(Maybe only a little, darker outline on the bottom side.)
I'm finding the shadows a bit
confusing, mainly due to the inconsistencies... I understand that most of
the "it" items (banana, coins, key, document, umbrella, etc.) - which
can't
be moved without picking them up, and which the marble can't move under,
only over - can have their shadow built into their actual graphic.
Anything
that can be moved, like a ball or a stone, or anything the ball can go
underneath, like the grate, needs a separate .png file for their shadow.
Correct?
Stones and Actors have their shadows in extra files named
"sh-objectname.png"
Items never have separate shadow files. Floors never have shadows.
For the latter group - the ones that need a separate .png file for their
shadow - how should the shadow be placed? Should it be centered in
the graphic, or should it be placed slightly down and to the right of
where
the actual item would be? Or is the placement of the shadows in
relation to the stones and other items built into the code of the game?
Let me show some examples.
Actor-shadows are centered (even when jumping, falling etc?) in files
with a size of 5/4 * tilesize (f.e. 48 px -> 60 px)
For the stones, it's more complicated, I have just found, that the sizes
are:
gfx32: 41px
gfx40: 51px
gfx48: 62px
But I don't know the exact rule here. Why 62 and not 61?
Then we could say, that the shadows are moved 11px to the bottom right.
For the placement of the stoneshadows, please look at f.e. "sh-shogun4.png".
@Ronald, Andreas: please correct me, if I'm wrong.
The current set of items is not very consistent concerning perspective,
shadows and quality. Concerning the size of the items we should take
into
account that a marble picks up a non-static item only if it
approaches the
center of the grid up to 0.3 grid-units (center marble - center grid).
Thus it may look strange if a marble rolls over a large item image
without
picking it up. I did not check if the current graphics take this feature
into account.
I haven't found that to be a problem. Maybe someone else who has been
playing the game longer would have a better idea.
Another topic would be the marbles themselves. Have a look at the black
marble. Its boundary is really not a circle. The white marble looks like
some one tried to enlarge the marble by a fuzzy white ring. The small
white marbles look even worse. The shadows are a subject of improvement,
too.
Please note that the actors should fit the physical radius. The 1.00
images do not always represent the real size of the actors. Furthermore
the actor images have to be centered. Me and Raoul did some minor
improvements on the development trunk concerning the last topic. But
improved images would be really nice.
I've already started working on these. If you can send me any
information that might help me regarding size, placement, padding and
so forth I would really appreciate it. I should mention, though, that
I already have new fg-blackball, fg-whiteball and fg-whiteball-small
images that I'm testing in my game, and I'm quite happy with how they
look. The only problem I've noticed is that my fg-blackball.png seems
a little too small for its shadow, even though I made it the same size
as the existing fg-blackball. But it functions very well in the game,
and really looks good, in my opinion. I haven't done any of the
variants yet - fall, jump, shatter, etc. Those will be a bit harder,
I think.
Information, ok, where to begin with?
I think with the physical actorsize.
Here are the actor-radius for all the actors:
ac-bug: 12.0/64
ac-horse: 24/64
ac-rotor: 22/64
ac-top: 16/64
ac-black/whiteball: 19/64
ac-whiteball-small/ac-killerball: 13/64
These values are measured in percent of the tilesize:
gfx32: 32px
gfx40: 40px
gfx48: 48px
The actorimages are stored in files named "fg-actorname.png". They have
the same size as their shadow images:
5/4 * tilesize, this makes f.e. 50px for gfx40.
The ac-blackball in gfx40 should have a diameter of 19/64 * 2 * 40 =
23.75 px
This will be always rounded to the next _bigger_ integervalue (here 24).
For the reason that all actorimages have to be centered in the
"fg-actorname.png" files, they should have an even numbered size. (That
is the problem with many of the current images ...)
@Ronald, Andreas:
What do we do, when the size is f.e 22.5?
Round to 23 and then, to get an even number to 24, or down to 22?
I think thats enough for the moment. If I forgot an important thing,
feel free to ask.
@Ronald, Andreas: please correct me, if I'm wrong.
The worst misfit between image and physics is the ac-horse. Its physical
diameter is 48/64 units. The image diameter is about 42/48. That is the
reason that horses can overlap. Please note the motif of the horse
has to
be maintained. It is a platform on which a marble can ride with a border
that keeps the marble from falling off the horse as long as the
acceleration is slow enough.
I don't seem to have an ac-horse graphics file. Is it the
fg-horse.png? If you'll send me all the information on it, I'll see
what I can do.
Yes, it's "fg-horse.png"
Please note that we may introduce higher resolutions in future. The next
image size would be 64 pixels. I guess it would be usefull to generate
directly this resolution for all new and improved images.
It was about a week ago that you sent this email, and in that time
I've completed several items and begun work on several more. All of
them will have 32, 40, 48 and 64 pixel sized images, as well as larger
images - usually about 200x200 pixels - that could be sized down in
the future if needed. I've made it-banana, it-key, it-ring, and
it-brush and I'm currently working on it-pin, it-sword and several of
the other items.
Great news!
For the files, I think, we should take the 200x200 into the
attic/gfx-templates archive.
With which programm do you work?
For GIMP, we would take the files in .xcf format. If you work with
Photoshop or similar, what would be good to use for archive porpose?
Regarding the it-key, is it necessary to have it both as an individual
file (it-key.png) and included in the items.png file? I can easily do
both, but I'm wondering if both are needed.
No, only one is needed. As we plan to split the items.png file to
several files "itemname.png" (reason is easyier administration), it's
not necessary that you add them into "items.png"
I think that's all of the questions I have for now. I'll be sharing
some of the items I've finished very soon.
Ok, I'm glad to see them.
