Hi @zep,
Unless I'm missing something obvious, I seem to have stumbled on a weird bug.
It seems that inside an FOR..LOOP (potentially other places too),
if the incrementor is something other than 1 or 0.5 (such as 0.4),
then even though PRINT is "saying" the value is 1.4, it is not comparable with that value
(perhaps a precision/rounding happening in PRINT?)
Code below:
cls()
?"-- works -----"
for z=0,3,.5 do
print(z)
if(z==1.5) print("😐")
end
?"-- fails -----"
for z=0,3,.4 do
print(z)
if(z==1.6) print("😐") --<<<< NEVER hits this
end |
Hope this helps (or someone can point out the error of my ways!)
Thx

So we now have 53x Free copies of PICO-8 to giveaway! 🥳
If you would also like to ADD to the Donations (but please, ONLY if doing so will not put you in any financial difficultly), then please feel free to message me directly on Twitter!
Why are you doing this?
PICO-8 has been, without a doubt, one of the best purchasing decisions I've ever made. 😊
It's brought me countless hours of joy, creativity and (in some cases) career opportunities.
From time to time, I see someone that seems very keen to start experimenting with PICO-8, but they simply don't have the budget for the (very reasonable) $14.99 price tag. It makes me wonder what they might've created, if given the option.
Well, I'd like for someone to have that option. 🤓
How do I enter?
To enter - simply reply to this thread, saying (in 50 words, or less)
- Why you would like to win and, ideally...
- What you would create with it (should you be lucky)?
What are the terms?
- Open to everyone, in all countries... NOW!
- (but PLEASE, do not enter if you already own PICO-8, or can comfortably afford it)
- Only one submission allowed, per person
- (don't attempt to abuse this - just be nice to others!)
- Closing deadline is this Saturday 6th July @ Midnight (GMT)
- After closing, all qualifying entrants' usernames will be fed into an online random selector
- (probably https://www.randompicker.com/)
- ...where 53 will be drawn at random, and announced here.
- I'll then ask the winners to contact me directly with their e-mail addresses, so that I can "gift" them each a copy of PICO-8.
- The organiser's decision is final.
Any other questions (or anything I've not covered), please let me know.
GOOD LUCK! 😁🤞
Hi all,
I'm producing miniature physical releases of Low Mem Sky (my attempt to "demake" No Man's Sky),
as a THANK YOU to my supporters on Patreon. 🙏
I not sure, but I think this is the first time anyone's tried (bothered? 😅) to create a "physical" release for a PICO-8 game.
For more information out how you could get one (and what else I've been up to!):

Hey @zep,
Looks like the ability to load carts via their BBS post ID is currently broken?
Which, with the current absence of the [Copy Cart] BBS feature - means it's a bit of a faff to load a BBS cart into standalone PICO-8.
Thanks in advance.
Paul

RELEASE HISTORY:
Hi @zep,
Before you pull the trigger on v0.1.12 - can I ask whether you've enabled extcmd in binary exports?
I just assumed it would work as the screenshot/gif record facility is there in exports, but when I try the code below on a Mac binary export (which is still 32-bit BTW), it does nothing:
extcmd("screen") -- works in PICO-8, not in binary export? |
Is this something that could still be rolled into the next version?
Thanks as always! :D

Originally created for #LD40 Compo,
but now finished and re-entered into @egordorichev's "Christmas Jam"
RELEASE HISTORY:
My entry to the 3-Color Jam (#3CJam), where you had to create a "spooky" game that used no more than 3 colours (and yes, Black is a colour!). It is an attempt to make a short adventure game, based heavily on the movie "Halloween" by John Carpenter.
I created it using my SCUMM-8 point & click adventure game engine (GitHub link)
| However, due to the BBS web player not hiding mouse cursor and right-clicks, I recommend playing it on My itch.io page (LINK) |
Also, for the best effect: turn the lights down and the sound up or headphones)! :D
CONTROLS:
- Mouse is recommended
- (Arrows / Z / X - will also work)
A "POINT & CLICK" PRIMER:
- If never played a "Point+Click" adventure game before...
- Simply use the cursor and (left) click where you want the player to Walk To.
- To interact with objects, click on the Verb you wish to perform, then click on the object.
- For example, to Pick-up the Knife... simply click "PICK-UP" and then click on the "Knife" object in the scene.
- When hovering the cursor over objects, their default verb/action (if applicable) will be highlighted. In this case, you can simply Right-click on the object for the default verb/action to be performed.

I also replaced the original credits with some shout-outs to the PICO-8 community! ;o)
Hope you like it and don't forget: the cake is a lie!
(P.S. - The original game music was done by Jonathan Coulton)

Hi all,
In case anyone is interested...
| AdventureJam returns for its third year of game development pandemonium as anyone with a computer, an idea, and an internet connection is invited to create an adventure game over the course of 14 days!
Whether you love point & click adventure, text adventure or exploring 3D environments, we want you to jump in and create a game that embodies the spirit of adventure, whatever that means for you! Adventure games have been around nearly as long as computers, and what began with words on a black screen has evolved into an amazing spectrum of gaming experiences. Let's celebrate the awesome legacy this genre has created with 14 days of pixels, puzzles, parody and pathos! AdventureJam will begin May 5th at 9:00 PM EST, and end precisely 14 days later on May 19th 9:00 PM EST. The voting process will follow immediately after the jam concludes, and will last until June 16th at 9:00 PM EST. So GET LAMP... GET SWORD... and GET READY... for AdventureJam! |
<SHAMELESS PLUG>
SCUMM-8, my point & click adventure game engine for Pico-8, has been included on the list of Resources.
So if you were thinking of making that style of adventure game, you may want to give it a try! :o)
</SHAMELESS PLUG>
Useful links:
- AdventureJam Home
- AdventureJam FAQ
- AdventureJam Resources
- SCUMM-8 (GitHub Home)
- SCUMM-8 (Wiki & API)
Good luck! :D
What is SCUMM-8?
SCUMM-8 is a PICO-8 "demake" of the SCUMM engine that powered most of the classic LucasArts adventure games, such as Monkey Island and Maniac Mansion. However, it is only (heavily) "inspired" by the SCUMM engine, not a true replica - for that you'll want good ol' SCUMM-VM.
My plan was to make it possible for anyone to make their own point & click adventure games in PICO-8!
All the code and API documentation can be found on GitHub (link below): |
Current Features
• Multiple Rooms (32+, technically)
• Pathfinding for walking
• Dialogs between Actors
• Cut-scenes
• Camera system (pan-to, follow, static)
• Room transitions ("iris", cut)
• Customisable Verbs
• Fake 3D depth "Auto-Scaling" of Actors
• Z-plane ordering of objects/actors
• Custom scaling for Actors/Objects
• Global-level (background) & Room-level scripts
• Game start-up script
• Object dependencies
• Replace Color (to allow re-use of room/object gfx)
• Adjustable Room Brightness Levels
• Screen "shake" effect
• Proximity (between Actors/Objects)
• Animations for Actors and Objects
Getting Started
The above "game" is just a silly demo that I created as part of testing the engine. Unfortunately, due to the large size of the engine + game code, it had to be "minified" to allow posting to the BBS. The original demo game source can be found here (link).
Please see the SCUMM-8 Wiki (link) for details on how to get started creating your own SCUMM-8 game, as well as the the full API reference.
Thanks
The following PICO-8 posts & resources were very helpful in the making of SCUMM-8:

• Overcoming tokens
• Sample Code: Screenshake and Fading
• A* pathfinding example
• Coroutines

Hi all,
(I am very aware that this is almost certainly a very stupid question, but if you don't ask...)
Does anyone know if it is possible to take some string content and convert it to functional/executable code in PICO-8/Lua?
[BACKGROUND]
I have LOTS of objects (tables) that all have their own, unique functionality. So unfortunately, there's little potential for sharing data/functions.
For example, many objects like this:
object_1 = {
name = "my object #1"
x = 8,
y = 4,
states = {145, 146, 147},
action = function()
-- code specific to this object here...
end
}
|
But as I don't need all these objects to exist at the same time (and could REALLY do with saving some tokens!), I'd like to somehow store these objects + functionality, e.g. within strings.
Then at a later time, restore these back into true objects/tables again.
Something like...
local my_stored_func = "function() -- code specific to this object here... end" local my_real_func = restore_function(my_stored_func) -- now execute the code my_real_func() |
I've seen similar potential methods of serialising/deserialising from strings - but at best it seems all I could store would be simple object properties (strings, numbers).
Whereas the real benefit for me would be if the whole object (or at least the object's functions) could be string-ified.
Again, I'm pretty sure I'm asking for the impossible, but if anyone has any suggestions that could help - I'd be very grateful to hear them!
Thanks! :D
TINY RIVER RAID is my submission to TRASEVOL_DOG's excellent "Tiny-TV" jam.
River Raid was my favourite game growing up with an Atari 2600, so I've tried to do my best to honour the original (quite tough with only 10x11 pixels!).
All levels are procedurally-generated, just like the original. So in theory, the game is endless!
INSTRUCTIONS
• Fly as far as you can down the endless river (don't forget to shoot bridges to enter new areas!)
• Look out for ships, helicopters, jets and oh... hitting land!
• Push forward if you wanna go faster (or pull back if you're scared) ;o)
• Finally... don't forget to COLLECT FUEL by flying over Fuel Depots before you run out and crash!

My PICO-8 tribute to one of the best games I've ever played... THE LAST OF US
(The original game music was done by Gustavo Santaolalla)
Hi all,
This is my first PICO-8 submission and, probably, my first ever (completed) game! :)
SLACKER is a tribute to classic "stacking" game that many of us wasted lots of time (and money) playing down the arcade. However, unlike the real one, this game is NOT rigged... (but it IS hard!) ;)
I've even included four possible prizes to select from, should you reach the top!
(who's gonna be the first to "catch 'em all" - no cheating!) ;)
Hope you enjoy it - I spent WAY too long on what was supposed to be a "quick game to learn PICO-8"
Updates in v1.2:
• Now supports 60fps (thanks to @zep for adding it to PICO-8 v0.1.9)
• Also made it a tad easier (was too difficult before - not sure it was really 'beatable'!)
Controls:
Z/X - Place Block(s) / Select Prize
Arrows - (not used)
--- Release History
1.2: Now supports 60fps and also made it a tad easier (was too difficult before!)
1.1: Removed exploit that made game much easier + added screen shake when prize drops
