We made this game for a PIGSquad (Portland Indie Game Squad) for a summer slow jam.
The Creative Theme was "Occult Classic".
So we made a game about a colt!

My all-time score=375! Post in the comments your best score!

Have Fun!

Hi everybody!

So, for a jam I'm far too unskilled to have considered, I'm putting together a little game where up to four players can pilot tiny ships and defend a fort. The ships can move about, and (eventually) shoot in the direction of a target that can be rotated around the ship by holding a button. It looks like this in practice:

(Enemies and animations forthcoming.)

Right now, I am attempting to optimize the code, because the player inputs eat a LOT of tokens in their current form. I currently have four different sets of inputs, one for each player, and each also moves a target that is specified as its own object (target1 with .x and .y, target2 with .x and .y, etc.). This is obviously no good, given the immense redundancies.

I think one could probably code a generic input function by making each target a property of its ship, using something like this:

function input(p)
  if btn(0,p.c) then p.x=p.x-1 p.targetx=p.targetx-1         --repositions player and target

About

An asteroid mining roguelike.

You mine pink and yellow minerals for coins.
You mine blue water that is used as fuel for steam power.
You mine brown regolith for shielding against solar wind.

Moving to an asteroid starts the mining process.

The shield and fuel costs are designated as brown or blue numbers in the center map. When you cross the numbers, your shields and fuel are decreased that amount.

High brown numbers indicate intense solar wind. High blue numbers indicate distant asteroids.

Any feedback is appreciated.

Hi,

I'm iterating over all map cells multiple times, to do various actions:

for t_x = 0, 127 do
	for t_y = 0, 63 do
		-- scan tiles
	end
end

for t_x = 0, 127 do
	for t_y = 0, 63 do
		-- do something
	end
end

for t_x = 0, 127 do
	for t_y = 0, 63 do
		-- place tiles
	end
end

This works, but uses a lot of tokens (do something is actually 4-5 different actions).

As there are a lot of interdependencies between cells, I can not do this:

for t_x = 0, 127 do
	for t_y = 0, 63 do
		-- scan tiles
		-- do something
		-- place tiles
	end
end

Instead, I wanted to do this:

functions = {
	scan_tiles(t_x, t_y),
	do_something(t_x, t_y),
	place_tiles(t_x, t_y),
}

for f in all (functions) do
	for t_x = 0, 127 do
		for t_y = 0, 63 do
			f(t_x, t_y)
		end
	end
end

But I never get the arguments passed to the functions I call.

How to go about this?

All help very much appreciated!

I'm having an issue where it seems like I absolutely cannot pass an argument to a function, no matter what I do.

For starters, I am using doc_robs' famous hitbox function:

  function player_hit(x1,y1,w1,h1,
                      x2,y2,w2,h2)
   local hit=false
   local xs=w1/2+w2/2
   local ys=h1/2+h2/2
   local xd=abs((x1+(w1/2))-(x2+(w2/2)))
   local yd=abs((y1+(h1/2))-(y2+(h2/2)))
   if xd<xs and yd<ys then
    hit=true
   end
   return hit
  end

So far, so good, right? Then I pass the following arguments along to it from another function:

  if player_hit(p1.x,p1.y,pw,ph,star1.x,star1.y,sw,sh) then
  --stuff happens in here
  end

All of the values in the preceding if statement are defined at _init(). The values pw, ph, sw, and sh are all 2, defined as global variables. The p1 and star1 values come from tables.

But every time I run my program, this error occurs:

A kind of Missile Command.

If you grew up with the NES, you remember that their basslines had a certain "snappiness" to them (for lack of a better word). Here are two of my favorite examples:

DAT BASS!

Anyway, I've been trying to mimic that type of bass as closely as I can in my PICO-8 carts, but I haven't quite hit the mark yet.

Does anyone have instrument/effect suggestions for achieving this kind of sound?

Flower March is a short relaxing experience made for the Harvest Mouse Jam. It's our first PICO-8 game and was a lot of fun to make!

After a freak laboratory accident, ninja-in-training Nina finds herself trapped in an alternate dimension where the walls shift each time she jumps. Now she must collect the scattered gears to fix this shattered world and escape! But with 32 challenging stages to outwit, that will be no easy task...

hey all!! sol here. it's been a while since my last game, but I haven't been resting on my laurels. this time around, I've made a puzzle-platformer with a focus on fast gameplay and a novel mechanic-- each time you press the jump button, the walls will shift between the foreground and background! you can also cling to walls and jump off of them to reach greater heights. I've built a lot of really tricky puzzles around this, so I hope y'all enjoy!

I think it's too late to suggest this, since you appear to have completely filled the printable characters with the kana glyphs, but just in case there's something to spare somewhere:

I just used one of the unicode thumb glyphs (👎,👍) and realized it'd be handy to have such glyphs in the PICO-8 character set.

I drew up some possible 7x5 PICO-8 glyphs for them:

You could type them with -/+ in glyph mode.

Even if they can't be fit into PICO-8 itself, the thumb-up might be good for the BBS, because I think a lot of people don't realize that's what the ★ glyph on BBS posts is for, given how seldom it seems to be used.

(I guess it's not a big deal if this isn't possible, though, since we can obviously just draw them manually.)

This is probably a ludicrously simple thing that I never learned, so please forgive me in advance.

I'm trying to write a function that checks whether a thing (star1) moving in a circle intersects with any of four lines (four_p_lineX) that connect to the circle. The best way I can think to do this is to make the function check whether the X and Y coordinates of star1 match the X and Y coordinates of any of the line endpoints.

The thing is, PICO-8 doesn't like what I've written:

 function check_direction()
  local s1switch=flr(rnd(1))   --You wonderful forum people can ignore this part.
  if (star1.x,star1.y)==(four_p_line1.x1,four_p_line1.y1) or
                        (four_p_line1.x2,four_p_line1.y2) or
                        (four_p_line2.x1,four_p_line2.y1) or
                        (four_p_line2.x2,four_p_line2.y2) or
                        (four_p_line3.x1,four_p_line3.y1) or
                        (four_p_line3.x2,four_p_line3.y2) or
                        (four_p_line4.x1,four_p_line4.y1) or

This bug has not been fixed since july 2017: https://lexaloffle.com/bbs/?tid=29699

Maybe it's on AZERTY keyboards only, but it makes the SFX editor painful. Here's what this layout looks like: https://fr.wikipedia.org/wiki/AZERTY#/media/Fichier:KB_France.svg
The keyboard we frenchies use. Sorry. We love our diacritics.

• the "6" key used for upper G# also decreases current pattern.
• the "," key (right to "N") used for lower B also decreases tempo.
  Those are really annoying. There's also this which are a bit annoying but I can do with:
• numpad "+" moves to 4 patterns forward while the "-" above moves only 1 backward.
• "=" (left to Backspace) moves 1 pattern forward while underscore ("8" main key) moves 4 backward.

Alt+Up/Down keys allow quick functions browsing in code editor, but oddly this is broken on the 3rd tab of my 5 tabs project, where alt+up/down won't go below the 2nd function (all other tabs are fine). Have no idea why, I even got rid of all my code & data to see whether this comes from that. This is the cart joined here: no data, only function names & some comments, but in tab 3 alt+down won't go under the parts_add function.

I've assembled the new Picade with a Raspberry Pi 4 inside. It boots on the NOOBS SD card, being myself rather a noob once outside of Windows :). Besides the recommended upgrades & updates, I've installed nothing else than the latest Pico-8 for Raspbian, as I want my Picade to be a Pico-8 machine first.

I launch Pico-8 with the command line and use splore to browse favourite games. Everything is fine until I relaunch games either by ctrl+R or the "run" command. And then it's the russian roulette: either the cart restarts, either it simply shut downs the whole Picade. Sometimes it happens after the 20th rerun or more, but this bug is so reliable I use it to turn off the machine instead of using the "shutdown" shell command.
