Not really fun, but I'm uploading to see.
Anyone have any idea how handling should work for a track of approximately this width.
No collision detection.
x to accelerate.
Sprite rotation using a function supplied by @freds72

I'm at a loss trying to decipher some code to better my understanding of core principles. Using the fantastic Advanced Micro Platformer by @mhughson as a subject of study I was reading into how the engine detects horizontal collision for the player. It does this through a collide_side function
function collide_side(self) local offset=self.w/3 for i=-(self.w/3),(self.w/3),2 do --if self.dx>0 then if fget(mget((self.x+(offset))/8,(self.y+i)/8),0) then self.dx=0 self.x=(flr(((self.x+(offset))/8))*8)-(offset) return true end --elseif self.dx<0 then if fget(mget((self.x-(offset))/8,(self.y+i)/8),0) then self.dx=0 self.x=(flr((self.x-(offset))/8)*8)+8+(offset) return true end -- end end --didn't hit a solid tile. return false end |
So I'm trying to make sense of this, and I can't seem to parse it in a way that makes sense. Breaking it down it assigns a local value offset to 2.66 roughly, because self.w is 8. And then it runs a for loop beginning at -2.66 through 2.66, with a "stride" of 2? So it counts up from -2.66 to 2.66 in increments of 2, and adds the current i to the y value? I assume this is checking for collision along the y axis of the sprite from top to bottom, but I cannot figure why it seems to check the y coord + -2.66, -.66, etc. So I assume I am misunderstanding something big.
And then it sets dx to 0, and then sets the player x to what I assume is the start of the wall tile. But I can't see where it accounts for player acceleration to adjust the end value, or how it compensates to avoid a "clip" into the wall.
I'm at my wits end trying to decipher this and further my understanding of how this math works. I've resorted to pen and paper drawing out different runs through this function, and it just seems like magic.
I'm wondering if anyone can help me, or otherwise direct me towards something to help me with these fundamentals. Happy Holidays!
Edit: Figured I'd link to the cart itself as well:

This is a preview of pico boulder dash.
(Not by Nizart, they just shared the cart on lexaloffle)
This game is under construction, hence it's posted under "work in progress".
However, the tutorial levels are already kind of playable.
Update 1
Now there are the first 6 levels of the classic boulder dash game included.
Update 2
I added a bunch of extra levels. Some of them a quite challenging.
Critical feedback is welcome!

Tents and Trees is a puzzle game with similarities to sudoku or minesweeper.
It's a special game for me because its success allowed me to go full-time indie game developer nearly 2 years ago.
Hope you'll like this PICO-8 version!

[O] (z/c): Run / Fly
[X] (x/v): Jump
Left / Right: Turn while in mid-air
v3 update: [X] also accelerates to make mobile controls easier
This is intended to be mostly a toy rather than a game, but you can get points for doing tricks!
Front / back flips (more points for 2x, 3x)
Early Santa: Santa lands early
Sneaky Weasel: Back flip close to the ground
Moon Grazer: Jump High
Glider: Jump Long
Fishtail: Do a bunch of wavey turns in mid-air
Firebird: Dangle Santa like he's the pod from the videogame Thrust
Santa Smash: Santa lands upside down. Don't do that trick.
This game is my contribution to the 2020 PICO-8 Advent Calendar. The calendar always surprises me with its sheer variety and depth of joyful creations, and this year is no exception! I encourage you to have a rummage around inside the advent calendar for the Full Experience (here's the menu cartridge), but to whet your appetite, here is also a partial gif dump:

ABOUT
This is a short but sweet game about trekking through the woods to make a special delivery.
This was made over parts of October and December 2020 for the PICO-8 Advent Calendar 2020. It was a great excuse for me to finally dig into some of the newer PICO-8 features added since my last big project, particularly tline and oval drawing.
Special thanks to thattomhall for playtesting and freds72 for providing me his textured polygon function! (It is used with minor modifications for drawing various elements of the house.)

My first Pico-8 game. Entered in Toy Box Jam 2020.
Tis the season to sing carols, drink nog, and decorate the night with Christmas sneks.
Press an arrow key to change the direction of the snek and connect bulbs to the live wire at the front of the snek to light them up. Build a long snek or a short snek. Ride the high speed rail to get around faster.
This is a mellow game with no set goals, but beware! If you touch the live wire to the snek you will create a short circuit!
When you are happy with your snek, press X to go to the forest and plant a tree decorated with your snek. Then go build another snek so you can plant another tree.
Merry Christmas and may 2021 bring you only good things.

WHO STOLE THE COAL?
A Personal Story and a Game
In 1977, I got an amazing gift from my parents...an Atari 2600. This game shares that story. (Company name changed for parody purposes.) It was one of the moments that changed the course of my life forever. Run the game to see that moment...
As for the game:
WHO STOLE THE COAL?
Santa got home and found no coal for his furnace! His house is cold. He hear whispers that the Abominable Snowbeast took all nine of his coal chunks, along with nine of his elves, and SIXTY of his cookies! Fortunately, the Abominable Snowbeast sleeps at sunset, so Santa can sneak in and get his coal back!

Controls: USE ARROW KEYS FOR SUBTLE GRAVITY.
Wanted to share my first proper pico project.
About having only one cigarette left (or not...? what?!)
I used this to make a music video for my band (see youtube embed). DISCLAIMER->GERMAN MUSIC
At the moment it's more of a demo/screensaver, but I would like to turn it into a minigame, or a system of mini games ; if there's fun in it somewhere. So i'm open to ideas :-)
Was thinking of the trope of an "alien brood mother" spitting out mini enemy's. (pack -> cigarettes)
And chaotic controls like only being able to apply gravity/momentum to all objects.
The physics engine is relatively sturdy, except for the lack of Separating_Axis_Theorem, some minor tunnelling and items getting trapped in each other.
I used Chris Heckers impulse physics articles from the 90s and a dynamically subdivided "intra-frame-crawl-while-loop-thingy" to resolve collisions chronologically. and the "Pool hall lessons" article on gamasutra for early false returns (which should be followed by an S.A.T. check which I have yet to write...) So could be waaaay more efficient.
Glad to share some cleaned up functions if anyone needs them (though the code is pretty legible).
important: USES METATABLE CHANGES FOR VECTOR MATH!! (see tab 4 / --metatables--)
Shoutout to the community for the amazing and helpful threads, and specially to lazydev @Krystman for his fantastic (and very funny) youtube series (LG aus Kölle).
Hope you get a giggle out of this one.
Merry Christmas,
Phume

I wanted to explore using Pico-8 to create quick artistic things. This is what I came up with while playing, and thought other newbies might be interested in how it works.
To get the Ninomae Ina'nis art in, I used GIMP to index the official art to a custom Pico-8 pallet.
Over-all, I'm kinda happy with how this quick toy turned out.

Candy Bomber
Original version released December 25, 2020
Based on Operation Little Vittles, this is "Candy Bomber." Fly your plane, avoid Soviet planes buzzing by, and most importantly, drop as much candy as you can onto the occasional pink airfields.
This game is dedicated to Colonel Gail Seymour Halvorsen of the United States Air Force, as well as all those who served in the Berlin Airlift. Halvorsen founded Operation Little Vittles, raising morale in the city of Berlin by airdropping candy to the residents below. His actions were initially unauthorized, but he soon became a national hero.
I initially wrote the basis of this game two years ago, but it sat unfinished until I decided to fix it up and release it this year. The code is barely held together. I regret not finishing this two years ago, or last year -- and I barely did this year due to a bad bout of depression -- but I felt obligated to finish it while Halvorsen, who is at the time of writing 100 years old and sadly in the hospital with COVID-19, was still around. Special thanks to kittenm4ster for their

Mines2
Back at it with a refactored version of the first Mines game. The goal here is learning and fun, and this project has been both of those for me.
Play
- Arrow keys to move around
- x to select tile
- z to set flag on tile
Features
- Minesweeper clone ('cuz there ain't enough of them)
- Level-progression game play
- Game field scrolls larger than game view to support super-big game fields
- Field continues indicator arrows
- Better performance at 30fps
- Intentional no mouse control to support handhelds
Hmm, that was shorter than I expected :). I wanted to refactor what I did in the first one and add levels. Which I did and they are working. It still ugly, but, well, okay. Could use some sound and music too 😉
