00:23:06 UTC touch keyboard design for pico-8 <p>the recent release of PICO-8 Education Edition proved that the PICO-8 editor can work on phones, but</p> <p>&gt; Sorry, touchscreen typing is not available ~ please plug in a keyboard!</p> <p>i know why PICO-8 doesn't support touchscreen typing:<br /> P8SCII is special, so it needs a special touch keyboard to work.</p> <p>the standard phone keyboard has no [ctrl] and [tab] keys, that are important for PICO-8 programming:</p> <ul> <li>[ctrl] is needed for shortcuts like [ctrl]+[s]=Save or [ctrl]+[g]=Grid</li> <li>[tab] is needed for code indentation<br /> (you can do this with spaces, but using tabs is the right way because you can change the tab width in Config)</li> </ul> <p>also, using [shift] in PICO-8 is much different than everywhere else:<br /> unless you choose to use Puny mode, [shift] switches the letters to glyphs instead of uppercase letters.<br /> so showing that on the keyboard really helps.</p> <h3>here is my PICO-8 touch keyboard draft</h3> <p>(in 1&times; scale, so that it can more easily be worked into an actual PICO-8 app)</p> <h4>default state of the keyboard</h4> <img style="margin-bottom:16px" border=0 src="/media/42335/keyboard_normal.png" alt="" /> <h4>default state of the keyboard; [ctrl] key activated</h4> <img style="margin-bottom:16px" border=0 src="/media/42335/keyboard_ctrl.png"

src="/media/42335/controller_pressed_right.png" alt="" /> <h4>controller; all buttons pressed</h4> <img style="margin-bottom:16px" border=0 src="/media/42335/controller_pressed.png" alt="" /> <hr /> <p>this is just a visual draft, so we need testing to confirm that it's comfortable to use.</p> <p>also, the images are wider than PICO-8's screen width of 128px, which i think is okay because real keyboards of retro computers always looked more crisp than their screens.<br /> if anything, the touch keyboard draft looks not crisp enough.</p> <p>we could use the pixelated keyboard for testing the form factor, because it's easier to edit than vectors.<br /> but once we know the final form factor, we can trace the pixel image in a vector program to get a realistically crisp keyboard.</p> Sat, 31

the tiles should be decorated.<br /> the last (4th) code page has only the main loop, and the first one has no code because it's for a bit of extra documentation.</p> <p>the <code>decogen&hellip;draw()</code> (decoration generation draw) function checks every tile for if it's one of the special tiles, and then decorates if it is.<br /> each tile has distinct decorations, so they have very different approaches to being decorated:</p> <ul> <li>pillars are generated from the base (the only pillar sprite in the spritesheet).<br /> they check for a ledge above to know how long the pillar should be.<br /> when they hit it, the rest of the pillar is drawn from top to bottom, with three parts <ul> <li>the base sprite but mirrored, is the capital (the top)</li> <li>a dark line shades the capital</li> <li>a rectangle connects the base and the capital</li> </ul></li> <li>every brick wall tile on the map checks if it is below a ledge tile.<br /> if it is, it draws a shaded row of bricks below the ledge<br /> using a one-off character that i made in <a href="">my one-off character creator</a></li> <li>the lamp's decoration has two parts <ul> <li>the pole is almost like a pillar, but in reverse:<br /> the lamp checks the tiles below the bulb (the only lamp sprite) until it hits the floor,<br /> then it draws the pole. it has four parts <ul> <li>mirrored base

needed.<br /> it has 4 parts <ul> <li>the top third of the door is another one-off character</li> <li>the row of bricks above is another one-off character, but only the bright pixels</li> <li>the single dark pixel of the brick row is drawn with <code>pset()</code></li> <li>i added a black outline to the left and right of the door<br /> using 2 lines</li> </ul></li> <li>the clock is also getting decorated with no checks. the decoration has 3 parts <ul> <li>a black filled circle for the clock face</li> <li>a bright hollow circle for the outline</li> <li>because the filled circle

so i made a color contrast table to make it faster than using the <a href="">contrast checker</a>:</p> <img style="margin-bottom:16px" border=0 src="/media/42335/47_color-palette.webp" alt="" /> <p>you can find the contrast level between 2 colors in the table by doing this:</p> <ol> <li>start from one of the 'BG' fields, corresponding to the background color you want to try</li> <li>navigate straight up or down the color palette in the same column.<br /> every field shows the contrast level of the color if used as the foreground color on top of the column's 'BG' color</li> </ol> <p>the numbers from 0 to 3 are contrast levels. the higher the contrast level, the better the readability. the contrast levels mean:</p> <table> <thead> <tr> <th style="text-align: center;">contrast level</th> <th>description</th> </tr> </thead> <tbody> <tr> <td style="text-align: center;">0</td> <td>❌❌ nothing is readable. 𝗱on't use colors with contrast this poor unless you can't avoid it, or on

center;">3</td> <td>β­•β­• large and normal-sized text are easily readable</td> </tr> </tbody> </table> <h2>πŸ’‘ secret tip</h2> <p>the contrast between 2 colors is the same when you swap foreground and background color.<br /> so you can not only use the 'BG' fields to pick a background color and the rest of the column to pick a foreground color:<br /> you can also use the 'BG' fields to pick a foreground color, and the rest of the column to pick a background color</p> <h2>ℹ️ information sources used</h2> <ul> <li>pico-8 color palette: <a href=""></a></li> <li>contrast checker: <a

(previous section), so this happened:</p> <p>when i watched <a href="">this talk about PICO-8</a> that i found on the <a href=""> PICO-8 resources</a> page, <a href=""> <a href=""> @zep</a></a> explained how data is stored in PICO-8 cartridges:</p> <p>&gt; all of the data is stored in the Red Green Blue data bits,<br /> &gt; it's encoded in the low bits of the RGBA channels</p> <p>so i made this cartridge by recoloring the original cartridge (previous section) with the paint bucket tool in <a href="">Pixelorama</a>.<br /> since he didn't say how many of the low bits of the RGBA channels are used, i found out myself:</p> <p>in my first attempt, i recolored the cartridge while keeping only the lowest bit the same as before:</p> <table> <thead> <tr> <th>&nbsp;</th> </tr> </thead> <tbody> <tr> <td>Recolored bits:</td> <td>βœ…βœ…βœ…βœ… βœ…βœ…βœ…β¬œ</td> </tr> <tr> <td>Unchanged bits:</td> <td>⬜⬜⬜⬜ β¬œβ¬œβ¬œβœ…</td> </tr> </tbody> </table> <p>i stopped halfway through to test if the cartridge would load in PICO-8, and the cart was corrupted.<br /> so glad that i saved it as 'welcome_special-edition.p8.png' and didn't overwrite the original 'welcome.p8.png' &mdash; although if i did overwrite that cart, i could redownload it from this post (previous section).</p> <p>in my second attempt, i tested loading and running the 'special edition' cart in PICO-8 very often, and i changed to leaving the lowest Two bits unchanged:</p> <table> <thead> <tr> <th>&nbsp;</th> </tr> </thead> <tbody> <tr> <td>Recolored bits:</td> <td>βœ…βœ…βœ…βœ… βœ…βœ…β¬œβ¬œ</td> </tr> <tr> <td>Unchanged bits:</td> <td>⬜⬜⬜⬜ β¬œβ¬œβœ…βœ…</td> </tr> </tbody> </table> <p>this time, even the finished version of the 'special edition' cart has unchanged PICO-8 data, but a different-looking shell. with roughly 1 to 2 hours of work in each of the 2 attempts, i did it.</p> <p>to generate the color codes that i needed, i did this in each cycle of color-picking (as needed):</p> <ol> <li>copy-paste the 'target color' and 'original color' into a Notepad (plain text editor) window, converted from Hex to Binary (in an online converter)</li> <li>copy-paste the Binary 'target color' in a third column, but change the low bits of each byte of the RGBA channels to the same-position bits of the 'original color'</li> <li>convert the new 'result color' back to Hex &mdash; also with an online converter &mdash; and use it with the paint bucket tool to replace the 'original color'</li> </ol> <p>here is a comparison of the original cartridge with the new 'special edition':</p> <table> <thead> <tr> <th>original</th> <th>special edition</th> </tr> </thead> <tbody> <tr> <td><img style="margin-bottom:16px" border=0 src="/media/42335/welcome.p8.png" alt="" /></td> <td><img style="margin-bottom:16px" border=0 src="/media/42335/welcome_special-edition.p8.png" alt="" /></td> </tr> </tbody> </table> <p>so it's the same cartridge as before, but with a blue-green shell.</p> <h2>2022-11-21: Welcome!
