This is my second upload (first was only music), though still not exactly a game.

The code looks crazy, and probably isn't the most efficient method, but it works! I'd love any tips on things I could do to improve this. Thanks!

Nice one! :D

You might wanna try following up with some "clearing" black streaks here & there (or something)?

Coz your effect at the start is great... but when it fills the screen with all green, it's less effective.

But again... a great first "visual" cart! :D

Looks great! My only suggestion would be to add some "eraser threads" that every once in a while go through a column and fade-erase as they travel through. Maybe use colors 3 to 5 to 1 as the fade colors?

Edit: Haha! Looks like @Liquidream beat me to it. :D

Thanks @Liquidream! I agree, the trails need to disappear after a bit, but that will be a project for another day, I suppose. :)

@MBoffin, I was trying to figure out how I could go about "erasing" the streams, your suggestion seems easy enough to implement. Thanks for that!

This is interesting. I couldn't resist to make my own Matrix screensaver for Pico-8. Uploading my best try so far...

Experimental vertical scrolling included (press buttons to enable). Enjoy!

Nice work @SkyBerron!

I took a slightly different approach, updated the cart at the top. Let me know what you think, everyone! :)

I think I'm done with this project for a while. I've added a bit of randomness to the number of threads and the length of the tail, and you're able to press Z to reset the program and get new random values. Surprisingly, I'm also happy with how sometimes a thread will overlap another, sometimes in front and sometimes behind, I enjoy the effect it produces.

If anyone else wants to make their own modifications, you're welcome to use my code. I'd love to see how others change this to make it their own!

looks good! maybe a bit black overall (needs more threads) ?

here's mine from last year:

not the best but hey, it's a tweetcart!

P#46190 2017-11-12 12:52 ( Edited 2017-11-12 17:56)

Here's a very simple one I made that uses custom 4x4 tiles. It also pops up a progress bar occasionally.

I wanna try this.

With blippers !

Hold (Z) to speed up.

Ultrabrite, I think you have the most compact one, well done !!

Here is yours with CR so the code can be examined:

for i=1,4096 do
  v=v and(v+6)%n or r(n)
goto s

UB, is there a web address or site where I can see more Tweetcarts ?

P#55583 2018-08-23 21:02 ( Edited 2018-08-24 01:30)

there's the old tweetjam 140 thread (https://www.lexaloffle.com/bbs/?tid=3726),
then there's the tweetjam 280 (https://www.lexaloffle.com/bbs/?tid=30213) that got less traction,
probably because it mostly happens on twitter now (#tweetjam & #tweetcart retweetted here thanks to ElGregos https://twitter.com/Pico8Tweetjam). FABULOUS STUFF!

I still screw around with my old tweetcart sometimes.

This is the current version:

Still not sure about using dark blue, or the flickering I'm doing to try to pretend there are more colors. Looks a bit janky to me. Might be better off with fewer colors and more stable. But that's where it is right now, anyway.

(Side note: I always think of the part where you're zooming through the text, which is why I use parallax and others generally don't. For a static camera shot, parallax is actually wrong, but it's my cart and I do it how I like.😀 What I really need to do is a version where you're literally entering the matrix, ie. moving into the text, but I'm not sure scaled text is a viable option on PICO-8.)

Now there's an interesting idea you guys just gave me, Felice.

Is it possible to have more colors on the screen than 16 ? Yes. Yes you can, and they won't be striped either.

I actually wrote an article about this, lord well let's see now. I'm this age now, I was 12 when I wrote the article for Call A.P.P.L.E. to show how to double the resolution.

HMM ! Long time ago. Let's see if it'll fly.

Done. Sorta ...


I blame ZEP. I betcha if we had 120fps setting it would work. :)

. . .

UB, I've spent all morning, afternoon and evening looking at and trying to understand the magic coding behind the the amazing TWEETS ! Good stuff !
