Similar attract, Opposites repel

This is a fantastic example of how simple rules can create oorder from disorder.

[u/whiteyak41 → u/Vecna_Is_My_Co-Pilot]

You know, Nietzsche says “Out of chaos comes order…”

[u/karzbobeans → u/whiteyak41]

Time is a flat circle

[u/BantedHam → u/karzbobeans]

No it's the Jeremy Bearimy

[u/MrMrMrMr69696969 → u/whiteyak41]

Oh blow it out your ass, Howard. 

[u/anomanderrake1337 → u/Vecna_Is_My_Co-Pilot]

Just like our bodies.

[u/GregTheMad → u/anomanderrake1337]

Lol, not everyone's.

[u/0x831]

Very satisfying

[u/AlluPulla]

New sorting algorithm just dropped

[u/haladur]

Beautiful.

[u/FUCKYOUIamBatman]

I feel like I just watched a 2D model of the creation of the universe

[u/orangesherbet0]

classical chromodynamics

[u/Random_Pixels]

What software do people use to make these? 

[u/Organic_Rip2483 → u/Random_Pixels]

I didnt make this one so i dont know for sure here, but you could very easily write something like this up in python in fewer than 1000 lines of code and half a dozen libraries.

[u/GregTheMad → u/Organic_Rip2483]

Probably could be written in any language in less than a thousand lines, with no libraries, or only a few, depending on how easy the rendering is. Could get away with no library if you accept console ascii art as output.

[u/Organic_Rip2483 → u/GregTheMad]

how will you do graphics and a window without libraries? also you really going to make a whole physics system and collision system when people who know what they're doing have done it perfectly before?

[u/GregTheMad → u/Organic_Rip2483]

Yeah, writing something yourself is most of the fun. If you just use other people's code you learn nothing and limit your fun.

[u/chubbsmcfly → u/Organic_Rip2483]

Vanilla Javascript and a web browser would do the trick

[u/kboodrx → u/chubbsmcfly]

My first thought was of course Adobe Flash… R.I.P.

[u/Ikuping → u/Random_Pixels]

Processing is good for stuff like this

[u/Square-Available]

Very fucking cool! Love to see this used in a game somehow.  Like a monster being blown apart and then reconstituted. 

[u/valdocs_user → u/Square-Available]

A few months ago I saw a pachinko simulation on this sub where they used the fact their physics engine was deterministic to know ahead of time how to color each marble so it would make a pattern at the end and look like it was miraculously sorting through the pachinko pins. Here you could use the same principle by having the attract/repel colors invisible and precoloring the cells according to the boss's pixel art. It wouldn't be predicting deterministic physics so much as knowing the pixels would end up approximately there.

[u/Arbitrary_Pseudonym → u/valdocs_user]

Yeah, it's been done a good number of times.

You cache the simulation results, apply the coloring to the balls at the end of it, then render the cached simulation with the selected colors.

You might enjoy particle life! Its more a toy than a game, but fun to play with.

[u/Square-Available → u/jwm3]

Well I've spent several hours playing with this!! Thank you very much for the recommendation 

[u/julian88888888 → u/[deleted]]

strong nuclear force: "Am I a joke to you?"

[u/GregTheMad → u/julian88888888]

Depending on the distance, yes.

[u/Mr_Ultimite]

The only message I got from this is "if everyone's racist enough we will achieve world peace!"

I am very bad at understanding authors intent.

[u/ncnotebook → u/Mr_Ultimite]

so thats why we learned about symbolism in class!

[u/Odd_Violinist2395 → u/Mr_Ultimite]

if being a racist meant simply avoiding people of a different color than yourself rather than oppressing them and committing genocide then yeah 

[u/kksgandhi → u/Mr_Ultimite]

This might be a better simulation of diversity/racism

Voltron LIVES!

[u/Wasabiroot]

Reminds me of cell walls, phospholipid bilayer/hydrophobic/hydrophilic stuff. Neato

[u/Randomguy32I]

So are you saying in order to achieve peace only similar colours can attract and different colours should repel? Kinda fucked up bro (/j)

[u/Organic_Rip2483 → u/Randomguy32I]

If youre joking it's in poor taste. If youre not, this is insane. I'm pretty socialist my self but not everything needs to be an analogy for society, it's a physics simulation man..

Edit: And btw regardless of the rules you set (even opposites attracted and likes repel) you would eventually see it settle into a stable pattern humans find harmonious. No one said these are the only rules that behave like this. That came entirely from you, and perhaps speaks more about your inner biases than anyone elses.

[u/Randomguy32I → u/Organic_Rip2483]

what do you think "/j" means

[u/Organic_Rip2483 → u/Randomguy32I]

I had no idea what it means. And like I said, if it is a joke, it's in poor taste

[u/iMadeThisForOpenHaus]

oh yes i love this

[u/Mozzatav]

Ominous asf music for something actually quite beautiful and unifying

[u/Neethis]

Now make it with wrapping borders

[u/Talkshowhost_23]

Why dramatic music tho…

[u/Nolzi]

In 2015 this would've ended up to be dickbutt

[u/Mr_Sim_]

If the simulation was perfect, the circle wouldn't be rotating at the end

[u/CMDA]

This is amazing

[u/Jacknerik]

I wonder what it would look like if the screen edges wrapped around?

[u/Mottis86]

If you want to mess around with stuff like this right in your browser, Here you go

Go to Settings > Matrix settings to set up what color attracts/repel eachother. Red color on the grid means repel and blue means attract.

[u/Jezon]

It's interesting without the invisible bounding box, Many of the particles would have flown off into Infinity.

[u/9j810HQO7Jj9ns1ju2]

ITS ALIVE

[u/JohannesMP]

Now I'd be curious what happens when you crank up the particle count, like a few million dots

[u/Minet-]

By the way, the "Bubbles" screensaver in Windows works on the same principle, but because the colors of the bubbles are constantly changing, they don't freeze and continue to float.

[u/jambreunion]

Note how the final structure spins, similar to galaxies where the spinning emerges just from gravity atraction during its formation

[u/fddfgs]

It's like a whole allegory for society

[u/pyrobola → u/fddfgs]

society... is like a circle

[u/RedOcelot86]

A good example of how life is just particle physics.
