World’s Smallest Game Engine
HTML-код
- Опубликовано: 23 май 2024
- In 7 days, I tried to make a game with the weirdest game engine: PICO-8, a fantasy console that tries to emulate hardware restrictions of 1980s video game consoles like the NES (1985) and SNES (1991). I teamed up with the insanely talented, professional, full-time game dev and pixel artist @ReeceGeofroy, who created the game’s art, and in one week we were able to put together "String Quest," a retro dungeon crawler game where you navigate two players connected by a string. This was also our entry to the Brackeys Game Jam 2021.1, which had a theme of “Stronger Together,” and the mechanics were inspired by Murphy's Walk, a game I made for the Extra Credits Game Jam #4 in 2019.

I think we made something pretty cool here dude! String Quest will become the next big NES Exclusive 🤩😏
Epic
easily the best game of 1985
I gotta say, very impressive, I can’t even do that myself, Reece and PolyMars have great potential and I hope you two succeed.
Did you say that because of PolyMars forced you? :D
There he is! Reece Geofortnite!
4:39 "Reece drew some spikes, and I made them kill you."
So poetic
i held my computer in the sky and cried because of how inspiring it was
wow i needed the subtitles thanks
@@scoutsrow lol
Everybody gangsta until the pixel t-pose starts bass boosting PolyMars out of his seat
why stop gangstaing when the pixel tpose starts bass boosting PolyMars out of his seat
@@Maxixe-nn1sr For some reason my idiot producer brain thought you wanted to say "gainstaging" and wondered how you managed to mangle that so much 🤣
:)
"remember saying enjoying making games with limitations? well not with core"
-Literally talks about one of the most restrictive modern game engines xD
@LeoGBA yeah I know you aren't really allowed to even criticise a product you're sponsored by most of the time
Just thought it was funny
I think he was referring to the "enjoying" part
When he said that I thought :
Well, he should have said " *just* like core"! 😂
Or, in a more LTT fashion: "and speaking of limitations, check our sponsor! Core!"
Isn’t made in unreal engine
i checked it out awhile back due to struggling with coding…but dude you can’t even import your own textures
1:20 aw man that hit me in the feels
oh hi rug, didn't expect to see you here :)
he was such a baby 😭
Polymars: Uses pygame, pico-8, unity, and SDL.
Also Polymars: Hey Bruh, checkout Core.
Why would he say no to free money?
@@jebbediahkerman768 Hi Jeb. I thought I killd ya.
SDL is good. Pygame is not a very serious game platform so it kind of gets a pass, and I'm not very fond of Unity but I suppose it has serious use-cases.
C++, on the other hand... Darn you Stroustrup. What did you do to my function pointers and my beloved structs?!
@@SimplyFizz Yeah the problem with python is that it's slow ...
core, aka high end roblox
Pico 8 games have given me some of my favorite browser games. Cool to see you trying it out.
Me too, some of my favorite games are made with pico-8
@LeoGBA wait w h a t
@LeoGBA no
theres a celeste 2?
where do i get
The Atari 2600 has 128 bytes of internal RAM and addresses 4 k of straight ROM before bankswitching and no frame buffering. I never want to hear programmers saying Not Enough RAM.
69 likes nice
There's an entire video by modern vintage gamer explaining why the switch doesn't have enough RAM for modern games.
@@bland9876 well it's not the problem of modern games tho, 4 gb of ram is not enough
The 2600 had no gpu either. The CPU did everything.
And for some reason empty GameMaker games are 50 MB in RAM. Literally a black screen is 50 MB.
Threatening people with a knife through a discord call. Surprisingly effective
top tip for collisions in pico 8: in the tile editor you can assign flags to a tile, then use the fget (i think) function to get the tile flags and check if it has the set "wall" flag you put on it. Saves you having to make a manual tile map table for every level
edit: lets go with those likes and that heart!
*this also works for spikes!
oh cool! I saw you could add flags to sprites and didn't know what they were for, but that would've been a lot easier haha
Hello polymars
@@ThePolyEarth oh no
@@ThePolyEarth cool logo ma'am, your moon looks majestic. I apologise if you're a mister :))
4:44 the code looks oddly like a gun...
It was his subconsious mind reminding him what to do if Reece GeoFortnite didnt cooperate
Ah, convincing your friends just like Dani does.
They really do have a way with words
With a K N I F E
@@geblordofchaos2965 shhhhhhhh
@@AidanTheBandit I often find the words “I have your family” particularly compelling
imagine making juno guys
"The enemies all have something in common"
*explains how they all have a position and all die when attacked by the player*
I was too busy vibing to the music to pay attention to the enemies
Jojo fan intensifies
Can we get Dani?
No we have Dani at home
Dani at home:
*but also talks about the code and is therefore superior*
YES I WAS ABOUT TO SAY THAT!!
But I still like PolyMars
@@ollerius0760 definitely yes
@HeladeraDragon what do you mean by that?
@HeladeraDragon dani swears in his videos yet you say he targets kids
@HeladeraDragon who

Oh ya, Mars is gonna throw the knife through the screen to hit Geo.....
6:39 Sad Rock :[
7:23 that looks like a gun
I swear most of the code look like guns
As a modder that programs in Lua, yes, tables are basically a solution to everything! Especially using the self method, as I've seen you wisely have
__index is useful too
and first class functions ;)
Lol roblox language
@@rbarbeats whats wrong with lua?
lol garry's mod MOD's language@@rbarbeats
Really cool video! I love the style of pico-8 games, and you made an interesting mechanic.
"use switch cases"
"Its in Lua"
"Oh, im sorry."
1:30
PolyMars: Not that far back
also polymars: *proceeds to go back further*
Great job editing and putting together a great video, it was a pleasure to watch
Fantastic work! Real good submission and great explaination.
For a game made in PICO-8, this is amazing!
Now try to do Basic or even 6502 Assembly for the Commodore 64.
Assembly x16 you mean? The one with instructions like sta, stx, sty etc.
@@stavros222 I've never heard it called x16, but yes, that is the 6502 he's talking about
poly mars is very friendly just look at his chat with reece! 0:50
Really fascinating book recommendation for anyone who wants to learn more about retro game development is a book called "I am Error." The book goes into detail about how games were developed for the NES and how limitations were overcame with some really creative solutions. Another one I hear is good (but haven't read myself) is Racing the Beam which covers development for the Atari 2600.
Anyways, cool looking game you guys, congratulations!!
ooh those sound interesting, I'll definitely check them out!
Mars
your videos are incredibly interesting ngl i really enjoy them
You're super talented. I'm 38 and still feel so behind, but seeing this makes me want to get so much better.
While PICO-8 is fun, it's a far cry from being anything close to old school game programming. Even when using new-ish game programming libraries like DirectX5 or 7 which have more graphically advanced features than the PICO-8, it was absurdly harder than this, no comparison at all.
Something that is closer and can be done with current hardware is making games in something like an ESP32 or ESP8266 (if you're up to the challenge) but that would only give you a taste, and from there you could go to some 8 bit microcontroller, although that wouldn't emulate the quirks of dealing with custom graphics chips older games used.
this is a really cool and insightful style of video!
Dude, your videos are awesome!
Nice video dude!
that sound at 0:43 got me every time
Awesome videos, keep it up!
Great video as always
Yes i agree
i love how poly added giorno's theme in the video
and it fits in so perfectly
I loveeeee pico-8 it's absolutely incredible
I love this channel yet it’s so underrated.
I will watch your channel with great intrest,
Or whatever it says.
3:20 Polymars realizing the magic of lua
Pico-8 is a really cool ide-type thing (yeah idk what to call it) and I’m glad you tried it.
Fantasy console
just from the title, i already knew that it was pico-8
Wow! Great stuff, dude! I wish I was like you 😭
This was such a cool idea for a video
I also remember making a game in 1985 using Lua
1:52 *i can hear the people at roblox filing a lawsuit*
the way you just inserted that sponsor was amazing
Dude love your vids
me, a Lua developer, seeing someone not use metatables : 😭😭😭😭
Why would you? I have made entire engines in lua without a single metatable
@@darltrash well if you are doing a functional style then it's not an issue, but he is doing object oriented style so it will be a memory management hell
@@sillyultroid nah not really, you dont really need all that crap and consider this is pico-8 which was designed to have limited processing and memory, so normal tables are just fine
not even april fools, just plain cool
i started watching your videos a day ago, epico
"Rust is for embedded systems" rhethoric vs reality of a functioning retro game in Lua. This is pretty amazing.
0:04 the left is a Dani reference
OH YOU DON'T KNOW WHAT KARLSON IS? KARLSON IS JUST A LITTLE GAME I'M WORKING ON-
Heyo! Whats that thing you guys used to like draw and plan stuff together?
i think theres a line-circle/square collision function already, no need to loop though points. game looks rad! great job!
Im a big fan!! your the best
8:32 so the real ending was about myself and how I can be who I want to be?
Evangelion Is a true beauty isn't it 😁
If you saw this reply then *congrats*
Friendly chat? I died laughing 😆
Loved the video!
I love this. One day, you will be a big content creator. Keep on expressing yourself in your content; I really enjoyed how organized and to the point this video is. And its a ride that gives you a little bit of fun along the ride.
I’ve used pico-8 I genuinely enjoyed it lol. I like pico-8 for a challenge and I like unity for high quality games. Still waiting for core on Linux :P
try love2D for higher definition games that are still written in lua! :D
9:14 how do I play on my 3ds? I didn't find any button to download a .cia file on the game's page
... You just need a browser/pico8 emulator
(And the card PNG is the actual game, yeah it's weird but pretty cool)
great vid keep it coming
I love your channel so much, and I’ve been trying to learn how to code in c++. I’m taking a course on RUclips cause I’m broke, and I was wondering, have you used c++ in any projects? (Besides that alien one I think) If so, what exactly did you do?
pico-8 is cool
Hi! Love ur vids
ok
good morning
U upload vid 3 mins ago, but u type dis comment 7 mins ago. How? Ur sis
I meant sus
when will we get rock for smash
What courses did you learn to make these! Just found your channel, and I already subscribed! Please let me know which courses you did in order to reach this level. Will be extremely helpful :)
CONGRATS, on the sponsorship, I know I was a bit salty at you for being so successful while making ok'ish code, but it's much harder making good videos.
I haven't seen enough of the video to comment anything bUT IM DOING IT ANYWAY >:D
how dare thy :0
if core is so good why don't you use it...
To be honest, the game engine isn't exactly aligned with the *CORE* content of his channel
Hi, I know that you will probably not answer, but who knows. Could you make a video talking about how you got to your level of programming? All the journey, courses, books or whatever, how did you learn everything that you know and an effective way of doing it. If you don’t wanna make a video about it, if you have time, I would appreciate text version of your answer. I’m just so hooked to programming overall, but I don’t know where to learn all this stuff, I’m just doing some courses, watching videos etc. Love your videos and thank you in advance!
Dude, if you don't have another project in mind, might I suggest programing for the NES? I would love to see you do more 8 bit shenanigans
bru i just subscribed a few minutes ago and already a new upload
"and when you collide with a wall, I check if it's a chest"
Computer Science moment
“then we fork the child”
Simple and effective. Congrats!
5:35 It's a rock
*Patrick* "Yep, he's got nerves of steel!"
I love the "pigo-8" console and all the games for it. It's so cool
TIC 80 fantasy console is cool too (despite taking too much idea from Pico 8).
BTW, at 8:12, you mentionned writing in code the coordonate of player spawn and enemy original position : wouldn't be easier to just use the tilemap for that?
I started learning how to code so that I could make a game. At one point I just stopped wanting to learn. When I saw this video I don't know why but now I want to continue learning. Thx :)
invite for next jam, I would love to go back to develop games, my big achievement was the first star wars game on mobile :), nice video! loved pico8
Kinda curious about a further in-depth look at functions within tables, never seen such a thing before and I wonder if it's a beneficial option for saving on tokens.
New polymars video pog
you need 10M subs ngl you are amazing
yo, super cool work! i recently bought something similar to pico8, and this feels inspiring, btw, i know is too late for feedback but it would had cool if the spikes had "blood" to represent them as spikes, at first i didn't get what it was
I love the retro style of pico 8 games. How did you find coding in the editor?
Hi! I am currently working on a top down rig dungeon crawler and I would like to know what software you used to plab the levels. Thank you!
700th comment! :) Great devlog and string quest seems very promising. Did you ever continue this project?
When polymars uploads a new video:
*clicks fast*
World’s Smallest Game Engine really needs some audience...
0:30 "i suck at pixel art look at my garbage"
*shows stylized pill doggo*
bastards lied to me
I just wanted to point out, you could have used the second "joystick" that PICO-8 has for true 2-player. You can fork the project and make a copy with this mechanic.
The last time I was this early, 8 bit gaming wasn't nostalgic, it was the future.
The worlds smallest game engine really needs an audience so if I do not find somebody soon
The rock enemy is written so beautifully, this enemy is going to make for some really amazing, interesting gameplay
i wrote this for u
My grandpa fought in Game Jam II
He was such a coder dude
I can't even finish learning java
Missed my Xbox, and left too soon

that's so insane
(Oh, my God) that's such a shame
Next to them, my games don't feel so grand
But I can't help myself from feeling bad
I kinda feel like two things can be coded (one, two, three, four)
The world's smallest game engine
Really needs an audience
So if I do not find somebody soon (that's right, that's right)
I'll blow up into smithereens
And spew my tiny scratch knowledge

And take a shot of Hennessy
I know I'm not there mentally

yeah, lua is data oriented. but it's actually amazing to code in with some graphics library
Nice, I have a suggestion tho,
WHAT IF YOU MAKE A GAME IN THE IPHONE SHORTCUTS APP
I was there for the stream it was great
Best thing about lua is using tables, direcotires and arrays to keep the code organized
5:01 New Final Fantasy enemy roster looking good.
