gradualgames [Lexaloffle Blog Feed] config.txt: fullscreen_method 2 works better on some machines. <p>I started tinkering with an _update60 cart the other day and I was getting stuttery behavior.</p> <p>Dug deep into possible performance bugs in my game. Then realized I had stuttery graphics (&lt; 60 fps) in simpler cartridges.</p> <p>Dug deep into updating drivers and BIOS on my Dell laptop. Still nothing. This laptop is from 2012, but is more powerful than my rpi3 which has no problem with _update60.</p> <p><strong><br /> Then, I took a look at PICO-8's own config.txt file and found fullscreen_method. Tried method 2, which is actual fullscreen rather than stretching a window.</p> <p>Totally resolved the issue.<br /> </strong></p> <p>How come 2 is not the default? Or maybe it is in fact the default and I'm forgetting having toyed with this months ago.</p> Tue, 12 Mar 2019 00:22:57 UTC 1 Knoll <p> <table><tr><td> <a href="/bbs/?pid=62396#p"> <img src="/bbs/thumbs/pico8_knoll-0.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=62396#p"> 1 Knoll</a><br><br> by <a href="/bbs/?uid=23858"> gradualgames</a> <br><br><br> <a href="/bbs/?pid=62396#p"> [Click to Play]</a> </td></tr></table> </p> <p>1 Knoll.</p> Sat, 02 Mar 2019 03:32:31 UTC Hobobot <p> <table><tr><td> <a href="/bbs/?pid=62308#p"> <img src="/bbs/thumbs/pico8_hobobot-0.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=62308#p"> Hobobot</a><br><br> by <a href="/bbs/?uid=23858"> gradualgames</a> <br><br><br> <a href="/bbs/?pid=62308#p"> [Click to Play]</a> </td></tr></table> </p> <p>Hobobot is about a robot that was destroyed and junked. But, his parts still work, and he wants to be whole again! Control each of Hobobot's two legs and two hands, and kick his head and get them all back to the torso!</p> <p>Controls:<br /> z - Switch hobobot piece under control.<br /> x - Perform action related to the current piece. Legs can kick, hands can grab.<br /> arrow keys/dpad - Move current hobobot piece left or right. Or, perform left/right action.<br /> enter - Bring up in-game menu. You must use this to restart the current level if you get stuck.</p> <p>The head cannot be controlled, you must kick it with one of the legs.</p> <p>There are 16 levels in total, which progress from fairly obvious mechanic-practice levels to mind-bending puzzles.</p> <p>Enjoy!</p> <p>I struggled with wanting to just keep working on this forever, but I'd rather release this and move on. Maybe I can make a sequel sometime, as it seems to be fertile ground for interesting puzzles.</p> Thu, 28 Feb 2019 01:43:34 UTC Gray scrollbar-like artifact in new Code display in web player <p>I love the new code display on the web player. I noticed one graphical artifact, which does not get in the way of reading the code but is nonetheless somewhat unpleasant. It appears like a second scrollbar, but is non-functional. See attached photo.</p> <img style="" border=0 src="" alt="" /> Mon, 28 Jan 2019 19:45:36 UTC &quot;Invalid cart format&quot; after web player boots. <p>Sometimes when I play a cartridge from the web player from my phone, PICO-8 will show the splash screen and boot text, and then it will stop before playing the cart, printing the message: &quot;invalid cart[ridge?] format.&quot; The issue can be worked around by refreshing, but whether it will then successfully boot appears to be intermittent and may require several refreshes. I have not seen the issue for a couple of days; but I realized I had not reported this nor had I seen it reported, so I thought it would be good to make a thread about it.</p> Mon, 07 Jan 2019 16:25:51 UTC Navigating away from a tab = no gfx update, but sound continues. <p>Sorry if this is a duplicate, but I could not find my precise issue in the bugs discussion.</p> <p>Running <table><tr><td> <a href="/bbs/?pid=60261#p"> <img src="/bbs/thumbs/pico8_snowman-5.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=60261#p"> snowman</a><br><br> by <a href="/bbs/?uid=23858"> gradualgames</a> <br><br><br> <a href="/bbs/?pid=60261#p"> [Click to Play]</a> </td></tr></table> in Chrome on Windows 7, I notice that if I navigate away from the tab and then back, that while I was not viewing the tab, graphics updates do not proceed. However, music continues. This breaks carts which rely on stat(20), stat(24), stat(26) etc. It is not a problem for me because I prefer to remain engaged with a cart as long as I am playing it anyway, but I am not certain if this issue was present prior to the recent updates or not.</p> Thu, 03 Jan 2019 14:15:34 UTC The Snowman (&quot;Walking in the Air&quot;) <p> <table><tr><td> <a href="/bbs/?pid=60261#p"> <img src="/bbs/thumbs/pico8_snowman-5.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=60261#p"> snowman</a><br><br> by <a href="/bbs/?uid=23858"> gradualgames</a> <br><br><br> <a href="/bbs/?pid=60261#p"> [Click to Play]</a> </td></tr></table> <br /> This is a little animation/transcription of Walking in the Air from &quot;The Snowman,&quot; an animated film from 1982 that I must have first seen in about 1987 or so. I recently watched this film again and it left a really strong impression on me, and I felt I had to make this little PICO-8 cart celebrating it.</p> <p>Update 1-1-19:<br /> Happy New Year! I made a few more improvements to the karaoke animation so the text scrolls more smoothly, the currently sung line is highlighted by a drop shadow as the ball slides across it. After more testing it looks like the code for tracking elapsed ticks is working great on all platforms. (except if you navigate away from PICO-8, there seem to be issues but it appears to affect other carts too not just mine?)</p> <p>Update 12-31-18:<br /> I added a karaoke style animation above the syllables of the words, and scroll the text so it is easy to sing along with. This was a little tricky to get working. I used stat(24) and stat(26) and associated ticks values with syllables, but it does not perfectly advance in lockstep to the 30 fps update so I had to fudge things a bit. But it now seems to be working well on Windows and on Mac, we'll see how well it does on web.</p> Sat, 22 Dec 2018 21:50:33 UTC &quot;COULD NOT CONNECT TO BBS&quot; when searching in Splore for &quot;short text&quot; <p>I wanted to see the code from the following cart: <a href=""></a></p> <p>I am unable to view the code from the bbs as previously.</p> <p>Also, searching for &quot;small text&quot; from within splore results in &quot;COULD NOT CONNECT TO BBS&quot; even though I'm able to refresh other parts of splore such as featured, new, etc.</p> <p>Thanks! (as a workaround, I'll just download the png)</p> Mon, 10 Dec 2018 13:41:23 UTC Separate metadata matrix (collision, other properties) from built-in map? <p>In the game I'm building, I often have a need for an entity to basically make the map solid and impassable at a given location, but in the actual map editor these spaces would all be empty. Since the &quot;flags&quot; all reside in sprites, it seems the only way I could have dynamic collision flags or other metadata would be to use my own collision map. It would first be built from the map itself, then used dynamically thereafter by entities that need it.</p> <p>It seems like a sensible thing to do and I am curious if anyone else has done this for similar reasons.</p> Fri, 30 Mar 2018 08:35:27 UTC Book: Programming in Lua: useful for Pico-8? <p>I understand Pico-8 has a subset of the full Lua language. However, I wonder is there enough of it there to make the following book useful: <a href=";psc=1&amp;refRID=JKY5ABS0S7DB70RF732Z">;psc=1&amp;refRID=JKY5ABS0S7DB70RF732Z</a></p> <p>Does anyone have this and did it help you?</p> <p>I've been able to get by picking up a smattering of lua syntax just online, but I enjoy the idea of getting a deeper look at the language. However since Pico-8 is the only platform on which I'm extensively using Lua, I want to make sure the investment would be worth it.</p> Fri, 09 Mar 2018 12:32:49 UTC How common is it to use classes/oop? <p>I've been using an &quot;object-like&quot; idiom in my Pico-8 programs so far where I have functions where I basically pass in a &quot;self&quot; and do operations on an object. I also tend to keep a &quot;type&quot; variable. That seems to have been enough to get as &quot;object oriented&quot; as I need to be. I've seen that it is possible to hack Lua to basically give you full oop and inheritance. It looks as though it is a hack and not a built in language feature, and from what I've been reading not very many Pico-8 users use it.</p> <p>My question is, to those that do, what do you believe the advantages are, especially in the context of making such small programs...? (guessing there aren't any, other than finding it interesting to implement)</p> Sun, 25 Feb 2018 22:33:36 UTC Is it possible to store favourites.txt in root path? <p>I have pico 8 on my home pc, my work pc, and my raspberry pi, but they each have their own favorites list. Is there a way to put this favorites list in the root path? I have all my carts and such in a dropbox share that all three machines use, but not the favourites.txt.</p> <p>Also is there a way to sort favourites.txt (other than just editing the file and sorting by the column of the title of the game)?</p> Tue, 08 Aug 2017 22:39:11 UTC Music editor...pattern length? <p>Is there any way to make a pattern stop short of 32 notes? (like famitracker has a Bxx effect for jumping to another pattern/frame) I have some music with a repeating section but it won't fit in 32 notes. if I could make it stop at say note 24 (or whatever it ends up being) I could repeat this section in a pattern and not have to waste an extra sfx.</p> Tue, 08 Aug 2017 21:24:00 UTC Dan O' Beekeep <p> <table><tr><td> <a href="/bbs/?pid=42844#p"> <img src="/bbs/thumbs/pico42865.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=42844#p"> Dan O' Beekeep 1.3</a><br><br> by <a href="/bbs/?uid=23858"> gradualgames</a> <br><br><br> <a href="/bbs/?pid=42844#p"> [Click to Play]</a> </td></tr></table> </p> <p>Fixing spelling of title that I thought I already fixed...</p> <p> <table><tr><td> <a href="/bbs/?pid=42844#p"> <img src="/bbs/thumbs/pico42863.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=42844#p"> Dan O' Beekeep 1.2</a><br><br> by <a href="/bbs/?uid=23858"> gradualgames</a> <br><br><br> <a href="/bbs/?pid=42844#p"> [Click to Play]</a> </td></tr></table> </p> <p>Added bee score counter so you know if you're going to beat the high score.</p> <p> <table><tr><td> <a href="/bbs/?pid=42844#p"> <img src="/bbs/thumbs/pico42846.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=42844#p"> Dan O' Beekeep 1.1</a><br><br> by <a href="/bbs/?uid=23858"> gradualgames</a> <br><br><br> <a href="/bbs/?pid=42844#p"> [Click to Play]</a> </td></tr></table> </p> <p>Fixed a couple of bugs.</p> <p> <table><tr><td> <a href="/bbs/?pid=42844#p"> <img src="/bbs/thumbs/pico42843.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=42844#p"> Dan O' Beekeep 1.0</a><br><br> by <a href="/bbs/?uid=23858"> gradualgames</a> <br><br><br> <a href="/bbs/?pid=42844#p"> [Click to Play]</a> </td></tr></table> </p> <p>Inspired by Dino Riki on the NES.

Right now I just keep a black strip at the top of the screen of my current game so that I can scale text whenever I would like.</p> <p>One idea I had was to create a table outside of Pico-8 that matches the Pico-8 font, and each row would be a single byte where every bit is a pixel, 8 bytes each for all characters in the font, then look up the correct bit when scaling each character, instead. Problem with that is the space it could use up, I guess.</p> <p>I was kinda hoping the font would be in some kind of pseudo &quot;system ROM&quot; readable using PEEK, but I didn't see this listed in the memory map.</p> <p>Another idea I had was to print every character, read the pixels and keep the data in a table. It'd be a sort of ugly &quot;blip&quot; of text right as the game starts up, though, but it might be so fast nobody would notice...</p> Sun, 09 Jul 2017 22:17:58 UTC My Pico-8 pi <p>Here's my Raspberry Pi 3, which I'm using as a dedicated Pico-8 machine.

It appears Pico-8 applies its own setting/behavior to this, it does not inherit it from the host operating system. I like to use very fast key repeat settings, in general. In particular it would be nice for using page up/page down to navigate a large program.</p> Tue, 13 Jun 2017 12:22:10 UTC Will MIDI keyboard input be added to music editor? <p>I'm simply curious to know whether midi input will be added natively to Pico-8. I enjoy composing in FamiTracker using my KORG nanoKEY2 (tiny piano keyboard for entering midi notes), and I really wish I could do the same in Pico-8. I guess there are workarounds for this, but, I'm still hoping this will be added in the future; it'd really push this product over the edge for me enjoyability wise.</p> Tue, 30 May 2017 09:36:45 UTC Largest possible rpg-style overworld? <p>I'm considering making a jrpg in Pico 8 at some point. Yes, I know it is a very tired genre. However I really don't mind, I still love it.</p> <p>One thing I was wondering was how to make an overworld that's larger than the 128x64 cels in the built in map memory.</p> <p>My current idea is to represent the overworld in terms of geometry instead of in terms of a grid, rendering the tiles manually (or temporarily filling a portion of the map cel memory). So I'd have like, a mountain range defined as a rectangle, and then I'd overlay rectangles to give them a shape, and have some logic for arranging the tiles around the edges to look correct, etc.</p> <p>Then individual tiny dungeons perhaps would just be hard coded in the map cels. Not sure.</p> <p>I have seen several adventure type games in Pico 8, but...are there any that are trying to give the appearance of being &quot;vast?&quot;</p> <p>I am really interested in the idea of packing a lot of engaging gameplay into a tiny space like this.</p> Fri, 19 May 2017 20:02:28 UTC Why Pico 8 stands out from other fantasy consoles. <p>I'm very fond of this idea of a fantasy console, and I'm enjoying Pico 8 a lot. Every so often, I think, gee, I'd like one with fewer constraints.</p> <p>But then something dawned on me: There must be a point beyond which, if constraints are relaxed too far, the point of being a fantasy console evaporates and you may as well be simply using a more generic game framework.</p> <p>I imagine this has been discussed many times before. But it explains to me why we will probably not see an extremely large proliferation of fantasy console software, the reason being that it is the constraints that make it unique as a console. If we make something as powerful as say protected mode DOS and make it a fantasy console, users may as well either use Dosbox or just write a game with a modern game framework, because the constraints are so relaxed relatively speaking. The craft of fitting a game idea into constraints is gone.</p> <p>I'm aware of Liko 12 and PixelVision 8 and TIC-80 and so forth. The point of my discussion here is just a thought experiment about how much folks would value something that's a lot more powerful---where at that point there's really no need to have it be a console.</p> Mon, 15 May 2017 12:04:57 UTC
