I hit an out of memory error and for once I don't know where the leak is...usually I know because the last change I made triggered it, not the case this time (or I just lost track of my shit) - either way, not sure exactly how to debug to trace it down.

Any tips or tricks are appreciated.

There were bricks in the sky. Why?

They fell on our cities - we did not like this.

We considered sending fighter jets against them, or surface-to-air missiles.

Wiser heads prevailed and instead an enormous, gravity defying bat was constructed, armed with spherical counter-measures and launched to protect us.

Sounds like the plot of a soon-to-be-commissioned movie (contact details in my about section).

--
Whelp. Arrows, X to serve. Bounce bricks for bonuses, multiple times for more.

There's only a few levels there at the moment, so I may add more. It might be a bit hard though.

Obviously I apologise for the 'music'. But nothing else.

UPDATE 1

This game is too hard! I've reduced the number of bricks, made the bat a bit bigger and added some multi-ball power bricks.

It's STILL too hard! Oh well.

UPDATE 2

Changed the bat controls to be less floaty (thanks for the feedback :)

Chris Donnelly (@gruber_music) has also very kindly spent some time on greatly enhancing the simple ditty I had playing, so there is now real music!

Here's a peek at a voxel based flight simulator engine that I have been working on.
The engine is heavily inspired by Comanche:
https://en.wikipedia.org/wiki/Comanche_(series)

I've been having fun with the smooth and seamless map generation. Perhaps other folks can make use of that code.

I don't think that I am ever going to get the frame rate up to butter smooth 30fps without dropping the res so low that things are unreadable, but maybe a flight sim can settle at 15 and be okay.

Updates:
--Added controllable ship with shadow
--Up and down controls height
--Z controls thrust
--Rings to collect
--F to explore the ship / return to flight mode

I was curious to know if there is a known memory layout of any of the PNG games.

I would be more than happy to write a comprehensive external graphic editor if I knew how to access the image files and where they are located in the PNG cartridge.

I have also tried passing the -width and -height flags.

I have absolutely no idea what's going on here, but after working on a game for an hour or so, the left and up buttons stop being read as input. btn() doesn't register them at all. Down, right, O, X, and all of player 1's buttons work just fine. Neither loading another cart nor rebooting fixes it; only manually restarting the console seems to help.

The keys themselves work fine in the editor and on the command line; it's only within a running game that they don't seem to register as button presses.

On Linux 64.

Anyone already have a function coded for checking to see if an x/y point is inside a rectangle with given points?

They're not "straight" rectangles, they'll be moving so I'm drawing them with 4 x/y points. I've found various formulas for getting the answer but wondering maybe someone had that done already? ...just being lazy... :)

This is my very first game I have ever coded. I am really excited, for (although the code is pretty sloppy) the game has turned out to be great in my opinion. The reason why the game version is "Beta... ish" is because I would not consider this as the "full version" of the game. The full version of the game will include a title screen, Boo boo bear, and some settings and other fun stuff.

Thank you for reading and for playing my very first game!

You are a slime, and you awaken in a slime factory (Because those exist now). Not only that, but you've been split into 21 pieces! The other parts of you must be around here somewhere. Explore this strange place to get yourself together and escape!

I am interested in purchasing the Next Thing's PocketCHIP which says it comes with PICO-8.

What I'd like to know is - does the PocketCHIP's PICO-8 come with access to DRM-free downloads for Windows, Linux and OSX, along with all future updates ?

To show some of my own 8x8 pixel work (which I've actually done now for several years), here is a sample.

This simple snippet triggers a crash in PICO-8’s internal ftan2() function:

atan2(-1,-32768)

Happens on both Linux and Windows.

Also, is this a bug? atan2(1/128,1/128) return 0.875 (the expected value), but atan2(1/256,1/256) returns 0.75. Looks like a bit of precision is lost somewhere.

I know very little about 3D graphics, but I felt my way around until I got something working :)

Z/X: Zoom in/out
Left/Right: Rotate

This cartridge is released under CC0!

Remade a game for the pico8 that I made a long time ago. Explore the cave, try to survive and collect everything before your fuel runs out! Beware of enemies, land on all the different colored flags to refuel and collect the golden cup to win. Avoid bumping into walls or the ceiling: it will rapidly deplete fuel for crashing.

Let me know what you all think!

Left/Right - Guide Helicopter / Select Helicopter on Intro screen
Z - Fly up
X - Shoot
Up/Down - Can aim rockets upward or downward

Unlock more helicopters at 2000,3000, and 4000 high score. This is pretty easy to obtain once you learn your way around the map a little bit.

Todo:
-Improve map
-Possibly add music
-Clean up code

v1.3 - Big graphics change, name change, Score when you get the cup is time-based.
v1.2 - New screen on game-over, a few other minor changes. Probably the last version for a while.
v1.1 - map2 memory reloading bug fix, added 3 unlockable helicopters with different stats
v1.0 - added an end game, finished up the map. It's finally a full game!
v.5 - added intro/ game over , high score, volcano enemy.
v.4 - Changed the map, added score and score pop-ups, added sounds, made enemies spawn based on map tile rather than manually adding them via code.
v.3 - Added two enemies, redid map, added unlockable doors via flags and destroying rocks. Redid some code
v.2 - Updated graphics, added platforms for fuel
v.1 - Basic framework for the game

Here's a little space shooter I made for my August #1GAM.

Music is my own chiptune cover of one of my favorite songs, "Scars on Land" by Kings of Convenience. https://www.youtube.com/watch?v=GNZZa9IYkPo

There are 6 waves of enemies. Try to beat the current hi score of 3110. Good luck and don't die!

Not much to say really, just something I knocked up in half an hour. Don't think it's bad for a first attempt!

Is it worth refining? Let me know.

Hi there,

I am a video and film editor based in the UK and am quite new to games programming. So new I haven't done any yet. But pico looks great. So I thought I should at least say hi!
