cairo installed (#333).cairo versions 1.17.4 to 1.17.8 may be
buggy (#334). We’ll now also raise a warning if a user tries to use
get_embedded_font() with these cairo versions.
These warnings have class "piecepackr_buggy_cairo" and can
also be suppressed by setting
options(piecepackr.check.cairo = FALSE).is_color_invisible() now accepts col
values of length greater than one.basicPieceGrob() no longer shrinks its background and
gridlines grobs if they would overlap with a transparent mat.pp_shape("kite") with default theta and
radius arguments now returns a slightly different “kite”
shape. Explicitly set radius = 0.25
i.e. pp_shape("kite", radius = 0.25) to get the old “kite”
shape (previously the “kite” shape couldn’t be altered at all by the
theta and radius arguments but with this
release it can).
The suggested package {xmpdf} is now required to
embed bookmarks and XMP/documentation info metadata into the pdf files
generated by save_print_and_play(). Please install the
suggested R package {xmpdf} and depending on what you
metadata you want to embed either the ghostscript,
pdftk-java, and/or exiftool command-line
tools. If you use save_print_and_play() to create a pdf
file and don’t have these suggested software installed you’ll get
message informing you that {piecepackr} was unable to embed
certain metadata. These messages have class
"piecepackr_embed_metadata" and can also be suppressed by
setting
options(piecepackr.metadata.inform = FALSE).
Some features which were deprecated by v1.10.3 (2022-03-23) have been removed:
use_pictureGrob argument of
grid.piece() / pieceGrob() which was
deprecated in v1.8.1 (2021-08-11) has been removed. Use
type = "picture" instead of
use_pictureGrob = TRUE. The ... has also been
moved sooner to where use_pictureGrob used to be in the
argument order so the arguments width, height,
depth, op_scale, op_angle,
default.units, envir, name,
gp, and vp must now always be named arguments
(instead of positional arguments).pp_cfg() R6 class public method
get_shadow_fn() which was deprecated in v1.10.1
(2022-02-22) has been removed. The public method
get_op_grob() returns the complete oblique projection
grob.animate_pieces()’s annotate argument must
now always be set as a named argument (or rely on its default value).
Setting it positionally was deprecated in v1.10.3 (2022-03-23).pdffonts (usually
found in poppler-utils) in get_embedded_font()
is now deprecated. Please install the suggested R package
{pdftools} (we now preferably use its
pdf_fonts() function instead).The following enhancements to the configurations returned by
game_systems():
dice_d4 which provide four-sided dice
in six color schemes (color controlled by their suit). Tetrahedrons with
the rank as a numeral at the top point (#286).dice_numeral which provide six-sided
dice with numerals instead of pips in six color schemes (#311).dice_d8 which provide eight-sided
dice in six color schemes (color controlled by their suit). Octahedrons
with the rank as a numeral at the top face (#312).dice_d10 which provide ten-sided dice
in six color schemes (color controlled by their suit). Pentagonal
trapezohedrons with the rank as a numeral at the top face. The rank of
ten is represented by a zero (#315).dice_d10_percentile which provide
ten-sided dice in six color schemes (color controlled by their suit).
Pentagonal trapezohedrons with the rank as a numeral followed by a zero
at the top face. The rank of ten is represented by a zero (#322).dice_d12 which provide twelve-sided
dice in six color schemes (color controlled by their suit).
Dodecahedrons with the rank as a numeral at the top face (#316).dice_d20 which provide twenty-sided
dice in six color schemes (color controlled by their suit). Icosahedrons
with the rank as a numeral at the top face (#317).dominoes_chinese and
dominoes_chinese_black which provide Chinese
dominoes and Asian-style
dice. dominoes_chinese has a white background with
black and red pips while dominoes_chinese_black has a black
background with white and red pips (#308).save_print_and_play() now uses {xmpdf}
to embed bookmarks, documentation info, and XMP metadata into the pdf
files generated by save_print_and_play().
{xmpdf} is now required to embed
metadata.ghostscript to
embed bookmarks and documentation info but can now also fallback to
using pdftk to embed bookmarks and documentation info.exiftool to embed XMP metadata including
document license information.save_print_and_play() will now inform users if unable
to embed metadata into the generated pdf file. These messages have class
"piecepackr_embed_metadata" and can also be suppressed by
setting options(piecepackr.metadata.inform = FALSE).Fixes a misrendering bug when using the new affine transformation feature that affected a small subset of game piece faces (#309).
Border lines in oblique projected pyramids are now correctly made
thicker/thinner when scale is different from 1
(#310).
pp_shape()’s gridlines() and
shape() methods takes new argument mat_width
which can be used to shrink them (to not overlap/extend past a target
“mat” effect) for most shapes that support a “mat” effect (but not
“halma” or “roundrect” shapes which will quietly ignore the
mat_width argument). This is now used in the default grob
functions.
The “kite” shape returned by pp_shape("kite") can
now be adjusted by its theta and radius
arguments.
The following enhancements to the configurations returned by
game_systems():
The dice in chess1 and chess2 now have
larger chess symbols (#318).
In dual_piecepacks_expansion:
In piecepack
In piecepack_inverted:
In playing_cards_expansion:
save_print_and_play() we fix rotation of pawn layout
when bleed = FALSE and size is not “4x6”.{rayrender} graphics system (via the piece()
function) has been updated to handle some breaking changes in the
arguments for rayrender::obj_model() (#304).piece_mesh() has been updated to handle some breaking
changes in {rayvertex} (#307).save_print_and_play() now supports new argument
size_bleed to add an additional “bleed zone” to the edges
of the print-and-play output size:
size of the print-and-play layout.NULL means no such bleed added to “letter”,
“A4”, and “A5” size layouts and a small bleed added to
“4x6” size layouts (1/16” to top/bottom and 3/32” to
left/right). Light prototyping at my local photo print service indicates
adding such a bleed delivers better results for 4x6 photo prints but
your results my vary.0.0393700787 to convert to
inches.arrangement = "double-sided".bleed argument which if
TRUE switches to an alternative layout which adds a bleed
zone and crop marks around the game pieces.save_print_and_play() is now 300 pixels per inch.game_systems().Some tweaks to the “bleed” zone feature introduced in v1.10.1:
grid.piece() / pieceGrob() if
bleed = TRUE and width or height
is not NA then width / height is
now interpreted as the size of the piece before “bleed” zone is
added.scale factor will now be applied to piece
dimensions before “bleed” zone is added.{grid} “grob”
returned by a custom grob_with_bleed_fn function is
bleed then pieceGrob() /
grid.piece() will adjust that grob’s bleed
slot to the requested “bleed” zone margins.There were some tweaks on how custom function style elements
(i.e. grob_fn, op_grob_fn,
grob_with_bleed_fn, obj_fn,
rayrender_fn, rayvertex_fn,
rgl_fn) in configurations lists are internally called by
{piecepackr}. If you use custom function style
elements it is possible you may be affected:
The arguments of custom functions are now called by name (via
do.call()) instead of positionally. If your custom function
uses the same argument names as any of {piecepackr}’s
internal custom functions then there should be no problem. The order of
arguments no longer matters but the names must match the names
{piecepackr} expects.
If one of the “named slots” of the {grid} “grob”
returned by a custom grob_fn function is
border then pieceGrob() /
grid.piece() will adjust that named slot to
FALSE and manually draw new border lines whenever
distorting the grob via the affine transformation feature
(#277).
If one of the “named slots” of the {grid} “grob”
returned by a custom grob_fn function is flip
then pieceGrob() / grid.piece() will adjust
that named slot to TRUE and draw it horizontally flipped
(via affine transformation feature) when drawing the “flip” side.
Currently most relevant when drawing on-their-side pyramids viewed from
their bottom.
If one of the “named slots” of the {grid} “grob”
returned by a custom grob_fn, op_grob_fn, or
grob_with_bleed_fn function is scale then
pieceGrob() / grid.piece() will adjust that
named slot rather than adjusting that grob’s gp slot’s
cex and lex values when
scale != 1. If your “grob” doesn’t have a named slot
scale you shouldn’t be affected.
A couple pp_cfg() R6 class active bindings which
were deprecated in v1.7.1 (2021-03-25) have been removed:
cache_shadow. Use the new cache_op_fn
instead.i_unsuit. Add one to the n_suits field
instead.cropmarkGrob() / grid.cropmark()
create/draw “crop mark” grobs (#262). Intended for use in creating
print-and-play layouts.
save_print_and_play() supports new argument
bleed (#259). If bleed = TRUE we provide a new
print-and-play layout with 1/8” bleed zones and “crop marks” indicating
where to cut the pieces. Currently this feature only supports
pieces = "piecepack", does not support
size = "4x6", and requires more paper than the more compact
legacy bleed = FALSE layout.
geom_piece(), grid.piece(),
pieceGrob(), pp_cfg()$get_grob(), and
pp_cfg()$get_op_grob() now support argument
type = "transformation" which uses the new affine
transformation feature introduced in R 4.2.
This should be a faster alternative to the existing “picture” and
“raster” types when wishing to “faithfully” draw game pieces outside
their “normal” (viewport) sizes and/or dilate them in x/y directions but
will only work in select graphic devices in R 4.2 (or later). You can
tell if the active graphic device supports the affine transformation
feature with
isTRUE(dev.capabilities()$transformations).
grid.piece() / pieceGrob() now has
support for drawing two-sided tokens stood up on one of their sides
i.e. (“top”, “left”, “right”, or “base”) in an oblique projection
(#272).
grid.piece() / pieceGrob()` now also draws more sides of
die and pyramid pieces when drawn in an oblique projection (#173,
#257).
Fully rendering the visible sides of the pieces requires the new
“affine transformation” feature which is only supported in select
graphic devices in R 4.2 (most notably the “cairo” family of devices).
If this feature is not detected we will output an inform()
message() of class
"piecepackr_affine_transformation" and fall back to either
a grImport2::pictureGrob() or
grid::polygonGrob() alternative. These messages may be
suppressed by setting
options(piecepackr.at.inform = FALSE).
pp_cfg()’s die_arrangement “style” now
supports comma-separated strings of six integers optionally followed by
a ^, <, v, >
which can be used to completely customize the arrangement of faces on
six-sided dice (#175). The die_arrangement “style”
continues to also support the values "counter_up",
"opposites_sum_to_5", and "counter_down"
(default) which provide aliases for three popular arrangements.
The following enhancements to the configurations returned by
game_systems():
dice_fudge which provide Fudge
dice in six color schemes (#287).op_angle, op_scale,
alpha, and scale arguments of
pieceGrob() / grid.piece() are now
vectorized.op_scale threshold when pieceGrob() /
grid.piece() switches from “oblique projection” mode to
“orthographic projection” mode has been lowered from 0.01
to 0.0001.isTRUE(capabilities("cairo")) then
pp_cfg()$get_raster() now always uses
png(type = "cairo").grid::grobCoords() now returns slightly better values
for dice, pyramids, and convex two-sided tokens when projected in an
oblique projection by pieceGrob() /
grid.piece() (#285).save_print_and_play()’s pieces argument
now defaults to NULL. If the size /
bleed arguments support the “matchsticks” and “pyramids”
pieces it defaults to
c("piecepack", "pyramids", "matchsticks") (as before) and
if they do not suport those pieces it defaults to just “piecepack”. We
are now more selective of which piecepack credits to include based on
which components are in the pieces argument.save_print_and_play() now shuffles tile back directions
(#103). If a user makes tiles by double-sided printing or folding over
the “gutter” and the tile backs are not perfectly symmetric then the
tile backs will now leak less information about the “direction” of the
tile faces.pp_cfg()$get_grob_with_bleed() and
pieceGrob(bleed=TRUE)) now better extends “mat” and
“gridlines” from the default “grob” function (#288).animate_piece() now correctly handles
n_pauses != 1.file argument of animate_piece()
ends in “.bmp”, “.jpg”, “.jpeg”, “.png”, or “.tiff” we will now save
individual images of the animation frames. file must have a
“C integer format” in the filename.save_piece_obj() if
options("piecepackr.op_scale") was set to a positive number
(#293).Upcoming breaking changes in R 4.2 for
grid::grobCoords() and grid::grobPoints()
required changes being made in {piecepackr} as well.
However {piecepackr} users probably won’t need to update
any of their code due to these changes (#270).:
{piecepackr} exports new S3 grobCoords() /
grobPoints() methods that works for grob objects returned
by pieceGrob() and pp_cfg()$get_grob() (for
type = "normal") as well as grob objects returned by
pmap_piece(). They return lists of lists with (x,y)
coordinates of the polygons that bound the game pieces in the format
expected for grid::grobCoords() methods according to the R
version number.grobPoints.piece() we now export the S3
method grobPoints.pp_grobCoords() and the grob objects
returned by pieceGrob() and
pp_cfg()$get_grob() (for type = "normal") now
inherit the additional class “pp_grobCoords”.size layout produced by
save_print_and_play() is no longer incorrectly rotated from
landscape to portrait mode (#269).animate_piece()’s annotate argument
unnamed is now deprecated. Instead either use its annotate
argument named e.g. annotate = "cartesian" or instead don’t
provide this argument (and let it use its default TRUE
value). In a future version this argument will be moved behind the
....save_print_and_play() no longer automatically
assumes that the generated print-and-play file should automatically be
released under the CC BY-SA 4.0 license. To continue to release under
the CC BY-SA 4.0 license you should set the cfg argument’s
spdx_id style/binding to “CC-BY-SA-4.0”
(i.e. cfg$spdx_id = "CC-BY-SA-4.0") before callingsave_print_and_play()`.
Several features that were deprecated in 2020 have been removed:
The following utility functions have been removed:
checkersGrob(c, s, t, n), use
pp_shape(s, t)$checkers(n, gp=gpar(fill=c)) instead.concaveGrobFn(n, t, r), use
pp_shape(paste0("concave", n), t, r)$shape instead.convexGrobFn(n, t), use
pp_shape(paste0("convex", n), t)$shape instead.get_shape_grob_fn(s, t, r, b), use
pp_shape(s, t, r, b)$shape instead.gridlinesGrob(c, s, t, l, n), use
pp_shape(s, t)$gridlines(n, gp=gpar(col=c, lex=l))
instead.halmaGrob(...), use
pp_shape("halma")$shape(...) instead.hexlinesGrob(c, s, n), use
pp_shape(s)$hexlines(n, gp=gpar(col=c)) instead.kiteGrob(...), use
pp_shape("kite")$shape(...) instead.matGrob(c, s, t, mw, n), use
pp_shape(s, t)$mat(mw, n, gp=gpar(fill=c)) instead.pyramidGrob(...), use
pp_shape("pyramid")$shape(...) instead.The following pp_cfg() R6 class public method has
been removed:
get_pictureGrob(), use
get_grob(piece_type, suit, rank, type="picture")
instead.The following pp_cfg() “style” has been removed:
shadow_fn, use op_grob_fn to indicate a
custom function for drawing in an oblique projection.animate_piece() can be used to create board game
animations using either the suggested package {animation}
or {gifski} (#251). Adding transition effects between moves
(i.e. n_transitions > 0) requires the suggested package
{tweenr}.
scale_x_piece() and scale_y_piece() are
wrappers around ggplot2::scale_x_continuous() and
ggplot2::scale_y_continuous() with better defaults for
board game diagrams. The functions returned by
label_letter() labels with letters,
label_counting() labels with counting numbers, and
breaks_counting() generates breaks at the counting numbers
to more easily generate (i.e. chess) algebraic notation coordinates as
commonly used in board game diagrams (#252).
The following enhancements to the configurations returned by
game_systems():
New piecepack_inverted configuration (#256). The
standard piecepack with its color scheme inverted. Intended to aid in
highlighting special pieces in diagrams.
New reversi configuration (#258).
"board_face" provides lined boards with colored
backgrounds. "board_back" provides checkered boards.
"bit_face" / "bit_back" provides circular game
tokens with differently colored sides: red paired with green, black
paired with white, and blue paired with yellow.
Improvements to save_print_and_play():
Now supports a dev argument and
dev.args argument that allows one to customize which
graphic device (and its arguments) is used to generate the
print-and-play files.
Now natively supports bitmap file formats “bmp”, “jpeg”, “png”,
and “tiff”. but output_filename will need to have a “C
integer format” in the string (e.g. "piecepack%02d.png") so
it can generate multiple “pages”.
Now supports size “4x6” to create a piecepack
print-and-play layout for 4x6 (photo print) size documents (#162).
pieces = "piecepack". Will
throw an error if you try to create (piecepack) “pyramids”,
“matchsticks”, or “subpack” print-and-play layouts.output_filename = "piecepack%02d.png".The license of the generated print-and-play file is now
customized by the cfg argument’s spdx_id
style/binding (#235). save_print_and_play() will then
create a license section with that license’s “full name”, a URL, and in
case of a Creative Commons license add a “button mark” badge. If left
NULL we will now omit the license section but print a
message saying we omitted it (unless
quietly = TRUE).
New argument quietly. Unless
quietly = FALSE will now message() about
missing metadata.
The “title” page was tweaked and improved. In particular it should now be able to handle any license with a SPDX Identifier.
Improvements to support adding a “bleed” zone around pieces:
pieceGrob() and grid.piece() now
support a bleed argument.
bleed = TRUE we add a “bleed” zone around the
piece.width and height should be the width and
height of the piece plus bleed zone. If width or
height is NA we will add 1/8 inch bleeds
(about 3.18 mm).bleed = TRUE is incompatible with
op_scale > 0.pp_cfg() now supports a
grob_with_bleed_fn style that can be used to set a custom
function for drawing the piece with bleed. The default
grob_with_bleed_fn function tries to guess a good solid
bleed color and draws it around the base piece.
pp_cfg() supports a new spdx_id “style”
and an associated active binding to update it. This is meant to refer to
the SPDX Identifier for the
graphical design license. save_print_and_play() can now use
this field to customize the License info for the generated
print-and-play layout (#235).
spdx_license_list is a dataset for the SPDX License List. It is intended
as an aid for developers writing print-and-play layout generators or
board game ruleset generators.
render_piece() should now handle its
dev.args argument properly.pmap_piece() now simply returns list() if
its .l argument has zero length or number of rows (instead
of throwing an error).game_systems()’s piecepack
configurations have been improved. The suit text on the backs are better
sized and the suit text has been removed from the faces.piece_side = "pawn_base" with
pieceGrob().The following pp_cfg() R6 class public method has been
deprecated:
get_shadow_fn(), use get_op_grob() to get
complete oblique projection grob.save_piece_obj() on a “joystick” pawn (returned by some
game_systems() configurations if
pawn = "joystick"). In general we cannot save Wavefront OBJ
files for “composite” pieces such as “joystick” pawns although
“peg-doll” pawns are an exception.New piece_mesh() function that creates
{rayvertex} objects (#247).
{rayvertex}.piece_mesh() creates
{rayvertex} object by setting rayvertex_fn in
pp_cfg() configuration list.piece_mesh can be used as the .f argument
in render_piece() (#255)The following enhancements to the configurations returned by
game_systems():
New function render_piece() renders an image of game
pieces to a file or graphics device. It is a wrapper around
pmap_piece() that can auto-size files and graphic devices,
apply axes offsets, annotate coordinates, and set up
rayrender scenes (#245).
New function geom_piece() provides
{ggplot2} bindings (#209).
aes_piece() helps create an appropriate
matching ggplot2::aes() “mapping”.geom_piece() requires a fixed scale coordinate system
with an aspect ratio of 1 as provided by
ggplot2::coord_fixed().geom_piece() also requires that cfg is a
character vector (and not a pp_cfg() object). In particular
if using op_transform() one should set its argument
cfg_class = "character" if intending for use with
geom_piece().{ggplot2}.New function aabb_piece() which calculates
axis-aligned bounding box (AABB) for set of game pieces with and without
an “oblique projection”.
New function has_font() which returns
TRUE or FALSE if it detects a given font is
provided by the OS. Needs either 1) Suggested package
{systemfonts} or
pdffonts installed.The R6 object returned by pp_shape() now has a new
pattern() method that fills the shape with a specified
pattern. Requires the suggested package {gridpattern}
(#228).
pieceGrob() and grid.piece() now
support a new type argument which modifies which type of
grid grob is used. Can be either "normal" (default),
"picture", or "raster". "picture"
exports to (temporary) svg and re-imports as a
grImport2::pictureGrob. "raster" exports to
(temporary) png and re-imports as a grid::rasterGrob. The
latter two can be useful if drawing pieces really big or small and don’t
want to mess with re-configuring fontsizes and linewidths.
Now defaults for the following piecepackr function
arguments may now be set globally via base::options():
piecepackr.cfg Sets a new default for the
cfg argument.piecepackr.default.units Sets a new default for the
default.units argument.piecepackr.envir Sets a new default for the
envir argument.piecepackr.op_angle Sets a new default for the
op_angle argument.piecepackr.op_scale Sets a new default for the
op_scale argument.piecepackr.trans Sets a new default for the
trans argument.{readobj} is installed then
the default piece3d() method will import Wavefront OBJ
files with readobj::read.obj() instead of
rgl::readOBJ(). In particular
readobj::read.obj() can successfully triangulate the
“meeple” shape and the “roundrect” shape (#220).alpha transparency parameter in
grid.piece() / pieceGrob().game_systems() now provides a message() if
style = "dejavu" and has_font("Dejavu Sans")
is FALSE.picturePieceGrobFn() when its
filename_fn argument does not support a cfg
argument.The use_pictureGrob argument of pieceGrob()
and grid.piece() is now deprecated in favor of the new
type argument. Use type = "picture" instead of
use_pictureGrob = TRUE.
rgl package
requirement to 0.106.8 in order to avoid a bug introduced
by 0.106.6).The following changes in pp_cfg() configuration lists
seem unlikely to affect any users (but theoretically could do
so):
"card_back" is now assumed to lack a “rank”.
To re-allow the appearance of "card_back" pieces to differ
by rank set the new lacks_rank style of
pp_cfg() to a character vector that does not include
"card_back"."piece_side" that is assumed to lack rank now is
imputed a rank equal to n_ranks + 1L when drawn (instead of
0) and for a "piece_side" that is assumed to
have a rank we impose an assumption that the rank will not exceed
n_ranks + 2L (replacing with n_ranks + 2L if
more than that). This now mirrors the pre-existing behaviour with suits.
For example if n_ranks is set to 6 then the style
background_color.r7 = "blue" will set the background color
for pieces that lack a rank to “blue”.Function game_systems() pawn argument
now supports a “joystick” value (#183). This allows one to draw a
“joystick” style "pawn_top" in {grid},
{rgl}, and {rayrender} with the “piecepack”
game system configurations.
"pawn_face") are not supported
in grid.piece() / pieceGrob() but are
supported in piece3d() (rgl) and piece()
(rayrender).as_top = "pawn_face" in
op_transform() (when using pmap_piece()).The configuration lists supported by pp_cfg() now
support two new “styles” (#237):
lacks_rank: a character vector of
"piece_side"’s that we should assume do not vary by rank.
By default these are the piecepack components that do not vary by rank
plus "card_back".lacks_suit: a character vector of
"piece_side"’s that we should assume do not vary by suit.
By default these are the piecepack components that do not vary by suit
plus "card_back".pp_cfg() objects now make their cache available as a
public field named cache (#242):
cachem package cache API. In particular one could choose
replace it with cachem::cache_mem() to cap the amount of
memory that can used by the cache. Note our cache uses keys that include
hyphens and underscores which older versions of the cachem
package did not support.pp_cfg() has a random prefix so (with a high
probability) multiple objects could theoretically share the same
cache.reset() method which clears it.The function that can be passed into the filename_fn
argument of picturePieceGrobFn() can now accept an optional
fifth argument named cfg that will (if present) be passed a
pp_cfg() object.
Can now draw “top”, “left”, “right”, and “base” “edge” sides of
two-sided tokens in grid (grid.piece() /
pieceGrob()) if not using an 3D oblique projection
(op_scale over 0) (#135).
grid.piece() / pieceGrob() (grid) when using a
3D oblique projection (op_scale over 0) but are supported
in piece3d() (rgl) and piece()
(rayrender).The “peg-doll” pawn (available via game_systems()
pawn argument) now has basic support for a piecepack
"pawn_top" in grid (#184). Previously only had support in
rgl and rayrender.
Piecepack pyramid dimensions have been fixed to better reflect
their actual physical size (#241). Their layout in the print-and-play
layouts produced by save_print_and_play() has also been
updated.
The appearance of piecepack pyramids returned by
game_systems() now more closely resemble the original
piecepack pyramids.
AA_to_R() is now more robust to minor numerical
errors in axis_x and axis_y values.
Fixed bug in op_transform() when calculating
“z”-coordinate when a piece overlaps with multiple pieces and the
“latest” one isn’t actually the “highest” one.
pp_cfg() objects now store more information in their
internal lists (which can be exported via as.list())
including any inferred n_ranks and
n_suits.
pp_cfg()’s print() method now sorts
fields by name and collapses vectors into a single string.
Several of pp_cfg()’s R6 class’s fields are now
active bindings.
Fixed bug when setting custom pp_cfg() configuration
list "rgl_fn" values.
The following pp_cfg() R6 class active bindings are now
deprecated:
cache_shadow. Use the new cache_op_fn
instead.i_unsuit. Add one to the n_suits field
instead.No user-facing changes (we tweak our examples/tests so R CMD check passes without issue on CRAN’s new ‘M1mac’ build).
Function game_systems() now returns the following
new configurations:
New alternative Wavefront OBJ file generating functions intended
to be used with the obj_fn attribute in
pp_cfg() “configuration lists”:
save_ellipsoid_obj() creates an ellipsoid piece colored
with that piece’s background_color. Currently used for the
go “stones” in game_systems() “go” configuration. Could
also be used for colored “marble / ball” pieces (#176).save_peg_doll_obj() creates a “peg doll” piece colored
with that piece’s edge_color and with a “pawn belt” around
its “waist” controlled by that suit and rank’s belt_face
component (#184).Function game_systems() now accepts new argument
round. If TRUE then the (retangular) tiles and
cards will have a “roundrect” shape instead of a “rect” shape (the
default) (#226). NB. piece3d (rgl bindings) currently
cannot import the “roundrect” shape.
Function game_systems() now accepts new argument
pawn. If "token" (the default) piecepack pawns
are a two-sided token with a “halma” shape. If "peg-doll"
then piecepack pawns will be a “peg doll” with a “pawn belt” (#184). NB.
grid.piece (grid bindings) currently cannot draw the
“peg-doll” style pawn.
game_systems() now have simple graphics using
this packages built-in meeple shape (#193).game_systems() now supports a 15th “Joker” “rank” for the
first four “suits”. This means all the Playing
cards in Unicode now has a corresponding card in the
“playing_cards_tarot” configuration (suggested Joker mapping is “White”
= suit 1, “Black” = suit 2, and “Red” = suit 4)pmap_piece() now simply returns list() if
its output has zero observations.file2grob() fixes a bug when importing images using the
magick package (currently any image that is not PNG, JPEG,
or SVG).save_piece_obj(): if multiple graphics
devices are open it should no longer accidentally switch the “active”
device (#239).save_print_and_play() now does six copies of the
“matchstick_face” component for six ranks and four suits. It used to do
four copies of the “matchstick_face” and “matchstick_back” component for
six ranks and five suits but a “standard” set of matchsticks is six
copies. If there is sufficient space it will also add some additional
(piecepack) dice (#194).There are no user-facing breaking changes in
piecepackr’s API but the internal grid
structure of the grobs drawn/returned by grid.piece(),
pieceGrob(), and pmap_piece() have been
changed to make it easier to query or edit the grid graphics post
initial drawing with functions like grid::grid.get(),
grid::grid.edit(), grid::grid.reorder() etc.
(#205).
grid.piece() and
pieceGrob() now has a “piece” class and “named slots” which
match the arguments of grid.piece().grid::grid.force() to view/edit
its internal grob “children”.grid::gPath.grobPoints() methods have been written for the “grob”
returned by grid.piece() / pieceGrob() and the “grob”
returned by pmap_piece().name in .l then
pmap_piece() will now generate/replace a unique
name by concatenating piece. with a unique
id if it exists or if it does not then by row number in
order to better label the “children” of the returned gTree
grob object (#223).The following utility functions have been deprecated in favor of
methods provided by the new pp_shape() object:
checkersGrob(c, s, t, n), use
pp_shape(s, t)$checkers(n, gp=gpar(fill=c)) instead.concaveGrobFn(n, t, r), use
pp_shape(paste0("concave", n), t, r)$shape instead.convexGrobFn(n, t), use
pp_shape(paste0("convex", n), t)$shape instead.get_shape_grob_fn(s, t, r, b), use
pp_shape(s, t, r, b)$shape instead.gridlinesGrob(c, s, t, l, n), use
pp_shape(s, t)$gridlines(n, gp=gpar(col=c, lex=l))
instead.halmaGrob(...), use
pp_shape("halma")$shape(...) instead.hexlinesGrob(c, s, n), use
pp_shape(s)$hexlines(n, gp=gpar(col=c)) instead.kiteGrob(...), use
pp_shape("kite")$shape(...) instead.matGrob(c, s, t, mw, n), use
pp_shape(s, t)$mat(mw, n, gp=gpar(fill=c)) instead.pyramidGrob(...), use
pp_shape("pyramid")$shape(...) instead.New function pp_shape() returns an R6 object that
provides the following methods to create various grobs for all the
“shape”’s supported by pp_cfg():
shape() returns a grob of the shape.mat() returns a grob of a matting “mat” within the
shape. Its argument mat_width controls how “wide” the
matting should be.gridlines() returns a grob of “gridlines” within the
shape.checkers() returns a grob of “checkers” within the
shape.hexlines() returns a grob of “hexlines” within the
shape.polyclip() returns a grob that is an “intersection”,
“minus”, “union”, or “xor” of another grob. Note unlike
gridGeometry::polyclipGrob it can directly work with a
pieceGrob “clip grob” argument.Default functions used by save_piece_obj(),
piece3d(), piece() now support a “top”,
“base”, “left”, and “right” side for the two-sided token components:
“bit”, “board”, “card”, “matchstick”, “pawn”, “saucer”, and “tile”
(#135).
Function game_systems() now returns a “meeple”
configuration with “standard” meeple “bit” pieces (#232).
pp_cfg() now supports a “roundrect” (rounded rectangle)
shape (#214, #229). Curvature of the corners are controlled
by the shape_r style.pp_cfg() now supports a “meeple” shape (#104). Meeple
coordinates were extracted from Meeple icon
by Delapouite / CC BY 3.0.pp_cfg() now supports setting multiple styles by using
a greater-than-length-one vectors (as well as continuing to support
previously-supported comma-separated strings).R_to_AA() now always returns an axis-angle
parameterization with positive axis_z value (#219).R_to_AA() for some 3D rotations with an
“exactly” 180 degree angle (in the axis-angle representation).AA_to_R() now accepts an optional axis_z
argument and automatically normalizes the axis vector. In particular
R_to_AA(AA_to_R(...)) can now be used to normalize
alternative axis-angle parameterizations with non-unit axis vectors
and/or negative axis_z values.is_color_invisible() will now correctly classify as
“invisible” colors with an alpha channel value set to 0.pp_cfg()$get_piece_opt() now
also contains a back value indicating whether this is a
back of a piece (and hence for some shapes may need to be flipped across
a vertical line) and a bleed_color value indicating a good
color for a “bleed” effect (e.g. for print-and-play layouts)
(#211).op_transform() for pieces whose “shape” is
a non-symmetric (across vertical axis) polygon.grid.piece() and pmap_piece() now returns
the grob invisibly if draw=TRUE as documented (while
continuing to draw the grob to the active graphics device).piece3d() will now try to infer a reasonable
textype value by manually checking the png texture’s alpha
channel.save_piece_obj(), piece3d() and
piece() now have support for 3D rotations of pieces (#188)
using an axis-angle representation parameterized by arguments
angle, axis_x, and axis_y.AA_to_R() and R_to_AA()
convert back and forth between the axis-angle representation used by
piecepackr and 3D rotation matrices (post-multiplied).R_x(), R_y(), and
R_z() create simple 3D rotation matrices (post-multiplied)
for rotations around the x, y, and z axes.to_degrees()
and to_radians() convert back and forth between degrees and
radians.pp_cfg() now supports new obj_fn,
rayrender_fn, and rgl_fn styles allowing
further piece customization within the 3D graphics functions
save_piece_obj(), piece(), and
piece3d() respectively (#200).piece3d() now supports user manually setting the
piece’s rgl “material” textype argument. When
textures with alpha transparency are not needed then setting
textype to "rgb" avoids a rglWebGL rendering
bug (#187).get_shape_grob_fn() now has a
back argument to indicate we are drawing the back of the
shape and should reflect it across a vertical axis (#218).board_face, board_back for representing
boards (#153).card_face, card_back for representing
cards (#124).bit_face, bit_back for representing
miscellaneous game pieces (#155).game_systems() now returns more game systems:
dice: Normal six-sided pipped dice in six color schemes
(#166).checkers1, checkers2: Checkered boards and
checkers. checkers1 has 1” cells and checkers2
has 2” cells (#168).dominoes, dominoes_black,
dominoes_blue, dominoes_green,
dominoes_red, dominoes_white,
dominoes_yellow: Traditional Double-12 pipped dominoes in
various color schemes (#159).playing_cards, playing_cards_colored,
playing_cards_tarot (#170):
playing cards is a traditional (French-suited) deck of
(Poker) playing cards.playing_cards_colored has five suits: red hearts, black
spades, green clubs, blue diamonds, and yellow stars.playing_cards_tarot is a (French Bourgeois) tarot deck
with four suits (hearts, spades, clubs, diamonds) with 14 ranks
(including knights) plus 22 trump cards (1-21 plus an “excuse”).save_piece_obj() for writing Waveform OBJ
files (and associated MTL files and png textures) (#189, #190). Note
support for dice and pawns are currently rather crude.piece3d() for making graphics with the
rgl package (#76).piece() for making rayrender
objects.op_transform() when sorting tile faces
rotated in various directions (#163).op_transform() now accepts new argument
pt_thicknessfor improved handling of stacked pyramid
(tops).edge_color for dice, pawns, and pyramids now
defaults to the background color of piece_side.edge_color for matchsticks now defaults to the
background color of the matchstick_back.game_systems() made more “standard”.pmap_piece() now supports an .f function
to specify the function to apply to the rows of the data frame. By
default it uses the (backwards-compatible) pieceGrob.pp_cfg()$get_depth() now has better depth calculation
for pyramid faces (representing laid down pyramids).pp_cfg() now supports a new op_grob_fn
style indicating which function to draw pieces with when drawing with a
3D oblique projection in grid. The older
shadow_fn style alternative is now deprecated.grid.piece() (and pieceGrob()) now support
a scale and alpha argument (#201).The following pp_cfg() R6 class public method is now
deprecated:
get_pictureGrob(). Use
get_grob(piece_type, suit, rank, type="picture")
instead.The following pp_cfg “style” is now deprecated:
shadow_fn. Use the new op_grob_fn
instead.game_systems() no longer returns an
icehouse_pieces configuration. Configurations for Looney
Pyramids can be found at https://github.com/piecepackr/piecenikrNew function picturePieceGrobFn() which returns a
“grob” function that imports graphics from files found in its
directory argument (#152).
New function game_systems() which returns a list of
configuration objects for multiple game systems (#157):
