Due to years of programming experience with CamelCase, I have written all my code in that format, accepting that it won't look right in the P8 editor. Everything has been working fine for me.</p> <p>I discovered today, though, that there's no mechanism for me to inspect values at runtime, since I can't type &quot;puny&quot; (uppercase) letters into the <strong>Esc</strong> command line. Thus I can't do<br /> print(myVariable)<br /> I tried copying from my external editor, typing in all standard-case, or pressing Ctrl-P. None of these helped.</p> https://www.lexaloffle.com/bbs/?tid=41069 https://www.lexaloffle.com/bbs/?tid=41069 Mon, 04 Jan 2021 18:22:48 UTC CrafDefense <p> <table><tr><td> <a href="/bbs/?pid=84851#p"> <img src="/bbs/thumbs/pico8_crafdefense-1.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=84851#p"> crafdefense</a><br><br> by <a href="/bbs/?uid=48525"> LtRandolph</a> <br><br><br> <a href="/bbs/?pid=84851#p"> [Click to Play]</a> </td></tr></table> </p> <p>CrafDefense is a different sort of tower defense game.

I was looking into how to do a fully custom cartridge label image. The only posts about it I found on the BBS involved creating the image painstakingly from 256 separate sprites, or using a script to muck around with the final .p8.png file. I wanted to have a quick and clean way to export from Aseprite into the format that Pico-8 saves into when using Ctrl-7. That way I can iterate on my label and my game independently of one another, with no extra steps.</p> <p>Fortunately, Aseprite allows custom scripts to export things. In lua, no less! Here's what you need to do:</p> <p>Make a 128x128 indexed image.</p> <img style="" border=0 src="/media/48525/NewSprite.png" alt="" /> <p>Select the Pico-8 palette.</p> <img style="" border=0 src="/media/48525/PickPalette.png" alt="" /> <p>Middle click on a color you don't intend to use in your image. That will set that color as the &quot;transparent color&quot; that will be erased to.</p> <p>Draw your cartridge label to your heart's content. Save it as a .png file.</p> <p>In File-&gt;Scripts, click on Open Scripts Folder.</p> <img style="" border=0 src="/media/48525/ScriptsFolder.png" alt="" /> <p>In the resulting folder, save the following code snippet as Pico8LabelExport.lua:</p> <div> <div style="max-width:800px; overflow:auto; margin-bottom:12px"> <table style="width:100%" cellspacing=0 cellpadding=0> <tr><td background=/gfx/code_bg1.png width=16><div style="width:16px;display:block"></div></td> <td background=/gfx/code_bg0.png> <div style="font-family : courier; color: #000000; display:absolute; padding-left:10px; padding-top:4px; padding-bottom:4px; "> <pre>local sprite = app.activeSprite local image = app.activeImage app.transaction(function() local outputFilename = string.gsub(sprite.filename, &quot;.png&quot;, &quot;.txt&quot;) file = io.open(outputFilename, &quot;w&quot;) for row=0,127 do for col=0,127 do pixelColor = image:getPixel(col, row) file:write(string.format(&quot;%x&quot;, pixelColor)) end file:write(&quot;\n&quot;) end file:close() end)</pre></div></td> <td background=/gfx/code_bg1.png width=16><div style="width:16px;display:block"></div></td> </tr></table></div></div> <p>Close and reopen Aseprite, to make sure it notices the new script. Open your .png, and click File-&gt;Scripts-&gt;Pico8LabelExport.lua. You will then have a .txt file next to your .png.</p> <p>To find out where those hex characters go, open your cart in Pico-8. Press Ctrl-7. It will create the <strong>label</strong> block of data. Replace it with the contents of the .txt file.</p> <p>Have fun!<br /> Bill Clark</p> <p>My first (partially completed) cart:</p> <img style="" border=0 src="/media/48525/crafdefense_WIP.p8.png" alt="" /> https://www.lexaloffle.com/bbs/?tid=40568 https://www.lexaloffle.com/bbs/?tid=40568 Thu, 26 Nov 2020 20:07:26 UTC
