Like the title says, the return value of :matmul, when passed true to indicate that the result should be stored in itself, is that same boolean value. This is inconvenient since it breaks method chaining. Here's a small repro as proof:
-- declare vector & metadata
local v = vec(1, 2, 3)
local m = userdata("f64", 3, 3)
m:set(0, 0,
1, 0, 0,
0, 1, 0,
0, 0, 1
)
-- ok, should return userdata
? "return type 1: "..type(v:matmul(m))
-- ok, stores result in copy
local vcopy = v:copy()
? "return type 2: "..type(vcopy:matmul(m, vcopy))
-- prints boolean, breaks chaining
local vcopy = v:copy()
? "return type 3: "..type(vcopy:matmul(m, true)) |

THIS VERSION HAS THE HALLWAY SCENE REMOVED SO THAT I DON'T NEED TO USE SHRINKO8
A simple roguelike game.
I'm still working on some things but the game is playable! The original game was created by Zach Gage and Kurt Bieg.
HOW TO PLAY
LEFT & RIGHT KEYS (Select your card)
X KEY (Attack with Fist | Use Potion | Pick up weapon)
Z KEY (Attack with Weapon)
RULES
- There are only 44 cards to the deck. (The RED face cards have been removed)
- DMD (Diamonds) - Are weapons you can pick up. If you have a weapon attached it will automatically gain a attack limit (BLACK card behind it). You can only attack monsters of the SAME or LOWER limit attached to the weapon. If you don't have a weapon or your weapon limit is too low, you can attack with your FIST.
- HRT (Hearts) - Health Potions. YOU CAN ONLY USE ONE POTION PER ROOM!
- SPD | CLB (Spades and Clubs) - Monster cards which rank from 2-14 (J(11),Q(12),K(13),A(14))
- Each new dungeon room has four cards to get past. Once you have 1 card left in your hand you move on to the next room.
- You have the option to FLEE a room if you choose. Those cards will be shuffled back into the BOTTOM of your deck. You cannot FLEE two rooms consecutively.
SCORING
- Getting out of the dungeon means playing through the entire deck. Once you have played all the cards and none remain, your score will be your current HP points.
- If you have ZERO HP points, the game ends. All monsters left in the dungeon are subtracted from your ZERO HP.

My first game!
This is my very first pico 8 game, i love how pico 8 looks and feels already!
I hope to be able to make more carts for the pico 8!
Revision 1
Added Help, fixed menu and bankrupt screen using X instead of O
Revision 2
Fixed bug where half of the Help button appeared on the bankrupt screen
sidenote: renamed the buttons in the help menu in revision 4 so
ideas for release 2.0
Milk and cocoa, not much but its another release

Found two bugs that I should report here:
Bug 1
This code doesn't compile - looks like lua's const feature breaks picotron's shorthands (are shorthands still using a preprocessor in picotron?)
local test <const> = 1
a = {3}
a[1] += 4 |
(same happens with close instead of const)
Bug 2
This code takes takes a ton of real time to execute.
This only happens due to the "<<32" and doesn't reproduce on the latest lua 5.4
t={}; for i=0,0x10000 do t[i<<32] = i end |
I was curious so I checked what was happening and it looks like the older lua version picotron is using is computing hash for integers based on the low bits, meaning large powers of two get really bad hashing. Some later lua version (still in the 5.4 line) fixed this to use modulo with a non-power-of-2 instead
