Feature Overview
DBG() Displays any timing value in real time.
- Executed with arguments, it stacks values for display.
- You need to specify 'd?' at the timing you want to display.
- When the stacked value display is complete, it is reset.
- This function consumes 71 Token.
function _update()
dbg('Debug Test!',time())
end
function _draw()
dbg('d?') -- 'Debug Test! [time value]'
end

This function will be included in the next version(0.14.0) of KNUTIL library.
If you want to stop processing and investigate detailed values, consider DMP().

HTD() Split a continuous string of hexadecimal numbers into a table.
- the number of supported delimited bits is 4,8,12,16 bits (1~4 nibbles).
- characters that cannot be converted to numbers are ignored.
- the result of the api's
tonum('0x'..v)of the api.
- the result of the api's
- depending on the delimiter, a missing last character will result in a lower digit by the number of missing characters.
- This function consumes 30 Token.
local a=htd('12a30f',1) -- a={1,2,10,3,0,15}

ECPALT() set transparency from palette table.
- Transparency is reset at each function execution.
- If the value of the "color id key" in the palette table is 0, the palette becomes transparent.
- The palette that was made black by
MKPAL()can be used as transparent as it is. - The format is redundant due to the specification to match
MKPAL(). - This function consumes 20 Token.
-- Make 6, 7, and 13 transparent.

MKPAL() Create a color swap table for use in PAL().
- This is useful for creating several color patterns.
- It is not an error if the number of elements in the swap table does not match.
- This function consumes 44 Token.
-- Color swap to darken "blue, white, and green".
local p=mkpal({12,7,11},{13,6,3}) -- mkpal('c7b','d63') is also the same.

Horizontal alignment is reset when a line break or tab is inserted in p8scii.
The example below expects the first line to start at the beginning of the first line after a line break.
Also, the tab position seems to reset the shift cursor.
cls() ?"\+jjtest p8scii\ntest p8scii (𝘹ADJUST:j)",0,0 ?"\+ljtest p8scii\ntest p8scii (𝘹ADJUST:l)",0,16 ?"\-jtest\-j p8scii (𝘹ADJUST:j)",0,64 ?"\-ltest\-l p8scii (𝘹ADJUST:l)",0,72 |
Feature Overview
OPRINT() Adds outlines to text and prints them.
- enclosure is not possible if tabs or newlines are included. (in pico8_v0.2.5.g)
- operation cannot be guaranteed if p8scii for decoration is included.
- Custom decorations other than outlines can be made by specifying a comma-separated p8scii as an argument.
- This function consumes 33 Token.
-- Split a pair of data and further split it into colors and names.
oprint('outline print',10,6,7,13) -- text, x, y, foreground-color, outline-color [, custom decoration]

This function is an inheritance of OUTLINE contained in the KNUTIL library.

When you see the default kana font, you might think that you could create something a little better.
But then you realize that it was a kind of provocation for creators (or designers).
Why the tilt?
Hiragana can be quite difficult to express in 5x5px.
One answer to this problem is a slanted design.
This allowed us to secure a space, albeit a small one, per character.

Notes
chrcode 144-153 are used as discarded kana.(ぁぃぅぇぉァィゥェォ)
It is quite difficult to maintain hiragana visibility at small sizes. As a desperate measure, I tilted the characters and crammed them into that area.
Katamuki = tilt
Feature Overview
MSPLIT() Converts a string into a table by splitting it with multiple delimiters.
- The default delimiter is " " for ease of data entry and readability(according to one's own preference).
- the default delimiters and numeric conversion flags should be modified according to your project.
- This function consumes 36 Token.
-- Split a pair of data and further split it into colors and names.
local value=msplit(
'10-yellow 11-green 8-red 12-blue'
,' ','-'
)
for i,v in pairs(value) do
local col,name=unpack(v)

EXRECT() creates a rectangle object with extended functionality.
- The created rectangle object can be drawn and its inclusions and overlaps can be checked.
- Drawing and update functions return their own objects, so they can be written in succession.
- This function consumes 388 Token.(include comb() and cat() functions)
r = exrect('10 80 16 24') -- generate a rectangle object from a string. x:10, y:10, width:16, height:24
r.rf(6).rs(7) -- draw "r" with rectfill, and then draw it again with rect.
?r.con(13,80) -- true
?r.con(9,80) -- false

Feature Overview
Capture the string for "One-off character" used in P8SCII from the sprite sheet and copy it to the clipboard.
- Simply print() the copied string to draw an image like spr().
- No decoder implementation is required.
!! Uses mouse control which does not work with BBS.
Please download and use it. !!
Type on your console
> load #p8ooccapture |
Note: Turn on "PUNY FONT MODE" when pasting into the code.
Depending on the character, sound may be made or the display of raw characters may be corrupted.
I have made one in the past with fillp and rectfill for equivalent purposes(FILLPatDraw), and I believe P8OOCPrint will be lighter and faster performing than this.
Control method
Printed samples of One-off characters
--** Add [\^.] to the copied CHARACTER and print(). **-- ?"\^.\0\14\14>>>\0\0" -- Tilted Heart ?"\^.\0\0「\0B<\0\0" -- Smiling mouth ?"\^.ヲュ◜◝◝○?゜" -- Tilted crystal |

Feature Overview
STRDSUM() sums two numerable strings.
- The number of digits it can handle exceeds the 32-bit limit. (Probably as long as the system will allow.)
- Match the string length to the longer of the two arguments.
- Negative values and values after the decimal point cannot be handled.(Insert a period in the output result.)
- This function consumes 63 Token.
This code may cause errors in versions prior to 0.2.5c.
?strdsum('32768','32768') -- 65536
?strdsum('500','000500') -- 001000
?strdsum('900109','123456') -- 1023565

Hello @zep
One of my game players reported this.
It seems that Pico8 games downloaded from Steam sometimes fail to start when a controller is connected.
Target game in which the bug occurred.
https://store.steampowered.com/app/1448220/KONSAIRI/
Running environment
- Apple silicon Mac.
- Gamepad "Sony PlayStation® DualSense™ Wireless Controller" ----STORE PAGE.
- Using Steam's controller linkage function (Bluetooth).
- Exported cart pico8 version 0.2.2c (also occurs in 0.2.5e)
Crash report

Thank you for your cooperation.
In the screenshot, the pause menu does not appear.
But in the case of GIF output, the pause menu seems to appear.

Feature Overview
BPACK() pack the value of the bit specification with bit width.
- By packs in the direction of low bits when multiple bit values are specified.
- By setting [number s] to a negative value, bit pack can be started from the decimal point.
- If there are fewer bit-width elements relative to the value to be packed, the bit-width elements are rotated.
- This function consumes 37 Token.
v=bpack({8,4},0,0xff,0xb)
?tostr(v,1) -- 0x00ff.b000 (bit-left-shift:0)
v=bpack({8,4},8,0xff,0xb)
