Multiply or Release - Cosmic Paint Battle #2 - Marble Race

In this mode:
Each player attempts to paint the whole map using their picture.
Image size is 1000x1000.
Upgrade available: increased starting number, higher multiplier, extra marble.
New in this version:
1. Gravity! When balls get big enough, the emit a gravity field that pulls other balls towards them.
2. On impact with other balls, some of the mass of the smaller ball is taken from both (in case of enemy collision) or transferred to the larger ball (in case of allied collision).
Contestants:
Hubble Deep Field
Cosmic Microwave Background
Pillars of Creation
Black Hole
Which will win?

I really liked the gravity/mass effect, made for an interesting dynamic :)

[@lostmarbles2d]

Thanks!

[@JamesTDG]

You can thank me for coming up with the idea, I just like seeing how specific IRL physics would make a game crazier

[@ehx3419]

I feel like this could be a specific ability of the Black Hole player. I also have an ability for Pillars of Creation: Every time a ball is released, all balls that are at least double as large release a ball of that size as well. If the ball is at least 10x as large, it releases a freshly spawned ball instead of splitting itself up. Not sure what Hubble Deep Field and and Cosmic Microwave might get, but I feel like it should be something that similarly gives them a slight edge.

How big do you want your Death Stars? Lost Marbles: YES Also... finally marbles were lost in the making of a video :D That death star broke the physics on a level that marbles started to have negative numbers :D

[@Interesting_Failure]

Lots to like about this one; cosmic effect is always cool, the gravity has a number of cool effects (although I suspect [REDACTED] would disagree, given what happened around 7:00...), and the upgrades are well-paced. Good music, too, and having the postgame is neat.

[@zunkman1]

Very nice, but I'd love to see the current multiplier somewhere on the screen.

[@boneguy4838]

The top left one is a little hard to see. I think there should’ve been an outline or a different background color. Other than that, great vid!

[@lostmarbles2d]

Thanks! I still need to get around to learning how to use compute shaders for optimization, which should allow me to do stuff like border detection.

[@ojchase]

It is a little challenging, but it's also the best outer space picture ever taken! Don't mess with it!

[@autumndragonfly.]

Love the gravity idea! Can you put the multipliers, # marbles and starting number somewhere? I like to see what the competition is up to lol

[@lostmarbles2d]

Right, I still need to do that! Thanks!

[@electroq2368]

2:46 While releases a ball right before a huge orange one hits it. What a lucky moment! :D

[@25penguin25]

This is so cool! I love guessing what the photos will be!

[@TheStormyClouds]

This is the coolest one yet

[@lostmarbles2d]

Thanks!

[@milkman4407]

Its really much better mechanically than charged shots #13 so YAY

[@W0lfi-lkc]

I am addicted to these in a good way

[@debogibson2843]

Cool gravity affects

[@mynintendogamingfeed5208]

The cosmic battles return. Accidental dislike removed; excellent paint battle.

[@JamesTDG]

Ayy, my gravity idea made it in!

[@lostmarbles2d]

I had been thinking about adding gravity to a video (not necessarily this one) for a while, so when you suggested it on this one in particular I knew it was time to make it!

[@guigazalu]

Next time, how about some kind of magnetic force? Equal colours repel each other, while different colour attract each other.

[@lostmarbles2d]

That's brilliant - wish I had thought of that! The biggest issue I had with this video was finding a good balance between mass, gravity strength, radius, increased mass/gravity based on size, etc. What usually tended to happen was that most of the balls would huddle together and just not go anywhere, because the combined gravity would just become so high. Adding a repelling effect between friendly marbles could hopefully resolve that, thanks!

[@ojchase]

@@lostmarbles2d I noticed your challenges getting the physics right and was about to gripe (gravity's range, too much momentum being transferred - some collisions are egregiously wrong, etc.) but I can see how you reached those choices because, yeah, otherwise it'll all just clump. You already have some brand new physics tampering with how the universe works in these, like completely elastic walls, and major violation of conservation of mass. I feel like those should help significantly. If you need more, a couple other possibilities to explore might be to have empty space have a gravitational draw, or captured space decay back to empty over time, or (I think most likely to succeed) have the bases themselves have a meaningful gravitational attraction. (The suggestion of a repulsive force is another great idea which I can't claim any credit for, but love.) Whether any of those will help with the problem, I don't know, but it might be worth a try. Regardless, I really really love how you added gravity into this one!

[@Interesting_Failure]

Yeah, there is the minor issue that gravity in the real world does, in fact, clump things together. I mean, I say it's an issue but in reality I'm kinda grateful.

[@guigazalu]

@@lostmarbles2d once I've tried creating my own particle physics simulator. Getting all the parameters (pixels to "meters", force field constants, particle's properties (mass, charge etc.)) into a form that's visually grateful to watch, is the hardest part.

[@lostmarbles2d]

@@ojchase Thanks! Regarding having the bases have their own gravity, I actually had that initially due to the ball that is currently being multiplied. The problem was that making a big ball would become a death sentence since it would attract all the other balls on the field to you and eliminate the player. I didn't consider the dark energy aspect... maybe something to investigate!

[@lukaskai1234]

yooo another cosmic paint battle let's goo, it's a shame we don't get to see the full pictures. i was thinking that you could perhaps add the 3 full images at each corner when the winning marble takes up all the ground. so, for example, when a marble wins, Lime would get the COSMIC MICROWAVE picture on his corner, so that people can see the image, even if that marble didnt win. also talking about the ending, i feel like you could make a super fast forward at the end so that the winning marble takes up all the space it needs to take, and also give the winning marble a bigger capture hitbox. it would still have the shape of a circle, but it would capture the pixels nearby as if it was a square, this should help with corners. also, the music here was nice, although it went a little bit empty at the end (makes sense, there is no sound in space) what wasn't super nice though in my opinion was the gravity. it looked cool, but it was a bit underwhelming, i was expecting marbles to orbit around a bigger marble, but instead they just instantly crashed on the bigger marble, sometimes even clipping out of bounds xD Examples like what happened at 7:00 were more similar to what i had in mind, that moment looked really cool (i was rooting for green :D)

Nghe xong bài này cái thấy tâm trạng buồn và nặng nề kinh khủng. Nhưng lại cứ phải replay hoài cả ngày😍

[@violet23266]

interesting video

[@dmitrytselpanau7128]

Спасибо!!! Готов сутками смотреть такое видео

[@JustAnotherCommenter]

How about a M/R with a small black hole in the middle that grows everytime a ball feeds it? Then Hawking radiation applies if not feeded in a particular amount of time (let's say 30 seconds of no feeding, the small black hole begins to shrink) The number of seconds required for the black hole to shrink is inversely proportional to the black hole's size (let's say 5 seconds for a big black hole)

[@lostmarbles2d]

Might be tough to balance, it has the potential of becoming so big that all shots are immediately sucked in. That's the situation I had during much testing on this video, a 10M+ shot with a radius covering the whole map would just immediately suck in everything. How about this: there's a star in the middle that has a fairly wide but not too strong gravity field. Mass that gets added to it increases its overall mass, and when it reaches a certain threshold it goes supernova, which destroys all balls currently on the map, and resets its mass to the starting value.

[@bambangmaulidin7633]

i like a huge map!!!!!!!!!

[@ShakeyBox]

Would it be possible to have the gravity effect work a little more like gravity in reality? Specifically, I was often expecting large objects to attract each other, but here gravity only seems to work when one object is big and the other is small. How are you calculating forces / accelerations due to gravity currently?

[@ojchase]

The incident around 7:00 shows a large object being affected by the even larger one. I can't see much effect on the larger one, but it should also be at least 4x smaller of an effect. Actually, rewatching, you might be on to something. I didn't see any clear cases of the larger pair being tugged (albeit slightly) by the smaller. Something else was excessively changing its direction (by way too much) too frequently to be sure.

[@ShakeyBox]

The specific effect I'm really trying to get at is that heavy objects don't "resist" gravity; if a small object's path is changed dramatically, a large object's path would also be changed dramatically in that same situation.

[@ojchase]

@@ShakeyBox re: "if a small object's path is changed dramatically, a large object's path would also be changed dramatically in that same situation." If I'm hearing you correctly though, it wouldn't. Or maybe we differ on what "dramatically" means. I agree that both large and small objects are experiencing the same forces. The gravitational force equation depends on both masses and doesn't give one a preference. Both experience the same force. But the acceleration (for the non-scientists reading: either the change in direction or in speed, positive or negative) would definitely not be equal. F=ma, which rearranged means that a=F/m, and if both objects have the same F but different masses, you'll see very different accelerations. For the incident at 7:05, the smaller curves about 35ish degrees. I would have anticipated the 3.5ish times bigger object to curve about 1/3.5th of that, or about 10 degrees down. ish. Small but I feel like I should be able to see that.

[@ShakeyBox]

They don't have the same F though. It's why a feather and a bowling ball fall together in a vacuum. F = G Mm/(rr) so a = F/m = G M/(rr) The acceleration depends only on r (the distance between the objects) and M (the mass of the object that is being accelerated towards).

[@ojchase]

@@ShakeyBox "They don't have the same F though." Yes, they do. You gave the correct equation for F_gravitational. Both objects have the same universal constant G, both use the same two masses, both have the same distance/radius values. How could you possibly get different F values? You've also reached the right formula for the acceleration, but are neglecting to reach the logical conclusion. You seem to be using the convention that "m" is the mass of the object that's going to move/experience an acceleration (which is the same m that's going to go into F=ma) and "M" is "the mass of the object that is being accelerated towards". I'm good with that naming. Calculating the acceleration for the small object, M is the larger object, and you'll get a large value. But when you calculate for the large object, the M it's being pulled to is that of the small object. The rest of a=GM/(rr) is constant for both items, so you should end up with very different accelerations. I suspect you're confusing your M/m values to assert both should accelerate equally. (The feather/bowling ball thing, which I am familiar with, doesn't help you here. I agree they only care about the mass of the earth, due to the correct acceleration formula you've come up with. But what we're trying to establish here is how much the earth "falls up", and no one's ever tried to claim that's happening at 9.8m/s. More like a nanometer.)

[@G.L.999]

[@tripplea_3338]

I think you kinda missed the chance to use other images of the same nature like nebulae other than the pillars of creation Like the cats eye nebula, and images of galaxys

[@lostmarbles2d]

I'll try that for the next one. The issue is finding pictures that are different enough that you can still tell the territory apart. That is why I selected the four images in this one - each one is different enough that you can tell.
