Show HN: AI game animation sprite generator
I tried to build AI game animation generator last year ( https://news.ycombinator.com/item?id=40395221), a lot of people were interested, but it failed, mainly because the technology was not good enough.1 year passed, there were a lot of developments in video/image generation. I tried it again, I think it works super well now. Actually beyond my expectation.You can generate all kinds of game character animation sprites with only 1 image.1, upload your image of your character 2, choose the action you want 3, generate!Support basic actions like Run, Jump, Punch and complicated ones like: Shoryuken, Spinning kick, etc.High quality sprite sheet will be directly generated to use in Unity and any game engine.If you are an indie game developer, you don't need to high an artist or animator to develop you game.For studios, it's 10x cost saving and 10x efficiency as no more creating animations for 100 NPCs 100 times.Please check it out, looking forward to your feedback!

The only reason this can generate images like these is because artists previously created artwork like this. And then in return they get:
> you don't need to high an artist or animator to develop you game.
Unless you created all the training material yourself, any model like this is highly unethical, in my opinion.
I don’t really care if the image gen models are trained on my renders or photos as long as they are open source.
Also I have been making the assets for my game which needs at least 2,000 sprites and honestly it’s very tedious and I’m looking to automate as much of the pipeline as I can so I welcome anything that removes the the tedium and pain from the process.
I do also think the threat is bigger to artists. Sloppy code will cause problems, and at some point you'll need someone who knows what's going on to step in. Sloppy art, a lot of people accept.
The “glitchiness” of the AI sprites can be quite unsettling because one can feel the something-quite-wrong that is difficult to place.
This is a worse state than using even rough illustrations by actual artists.
If one must use AI for this I would recommend having an artist in the pipeline who uses AI to create assets but then makes sure they are seamless.
I remember when 3D CG was new and it got so much hate for not being "real art". I heard the same drama happened when Photoshop and Illustrator hit the market, they weren't considered "real art".
>The training data for LLMs is stolen. I don’t mean like “pirated” in the sense where someone illicitly shares a copy they obtained legitimately; I mean their scrapers are ignoring both norms and laws to obtain copies under false pretenses, destroying other people’s infrastructure.

There is nothing stopping artists from using A.I. to improve their work. The sketch to image work flows are great, the variation work flows can save from the tedium and inpainting can help fix and improve images.
Text to image is lazy and is the cause of most of the slop but no one is saying artist should replace their Wacom tablets with text prompts. I feel like there is a lot of hurt egos going on. I remember back in the day on CGtalk, there was so much elitism and in hindsight it probably held a lot of people back, myself included.
Computers have no such limitation and can consume almost the entirety of a subject’s work in a few weeks or months. I think that alone is enough to say that yes, it is fundamentally different.
There is no fundamental difference.
My argument is precisely that the mechanisation of information is fundamentally different from the scale at which a human can learn. One immediate consequence being there is no longer a natural brake on the scale of what can be sourced for use in a derivative work.
To be clear this is not a value judgement, just to point out that it _is_ different, just as driving is fundamentally different from what one can do with one’s own feet. Of course the mechanisation of transport is history and seems daft to argue against. But it is different. Whether that’s good or bad is a much harder question.
2. Making something public isn’t always a choice made by the creator
3. Making something public does not denote fair use, this is why copyright (albeit arguably a poor solution) exists
4. These LLMs consolidate wealth into a small group using outputs from a larger, often less wealthy group (creatives) without fair compensation
AI can't take away an artists creativity, just like how photography didn't kill painting. Yes, it closes up certain avenues on how artists make money but it will most probably make up for that by making them more productive.
How?
AI can't take their creativity but it will take their means of survival so a few companies can profit instead. Yeah, great trade-off.
For purposes of generative worlds, I have an additional requirement for interchangable equipment and weapons. I.e. a single sword or armor sprite should fit with all humanoid characters, in all animations. I suspect this could be achieved by training against "clipping" tests.
As a start, there should be projections for all four cardinal directions.
Limit the output to palettes of a given size, for classic recolors via GL shaders.
I like the "interchangable equipment and weapons." idea, very cool. And yes. it's doable. many ways possible could work. I'll experiment.
Staying focused: the panda is wearing gloves, but then when it does the Hadouken and the Hurrican Kicks, it loses the gloves.
Bigger picture this seems like a focus on product stuff like pricing and demos and navbars that don't really matter to artists or game developers. Your feelings are correct that people here - the root motivation of the negativity - are questioning your sincerity. With AI art this is acutely true, people don't view AI art as a sincere art endeavor. I don't doubt your sincerity. But spending more time on the art thing, and making it free or open source, it's going to look and feel more authentic.
I've been toying around with the exact same idea the last couple weeks. It's mostly GPT 4o image => some image cleanup, but honestly a lot more finicky than I originally expected. Lots of prompt engineering. So OP probably put in a fair bit of effort here.
Also each animation probably costs $1-$2 in GPT costs to make [1], so not something that's easy to throw a free tier on.

To the poster, please find the customer service to fix

Also, I cannot find my queuing job after closing the page.
I've fixed it.
ALso given your account 2x more credits.
I’d love to hear a bit about the ML side of things: what was your experience with various models? Do you see a clear cost vs quality tradeoff with current state of the art models? How do open vs closed models compare?
The GitHub cat in the footer does not link to GitHub either.
Also, why does the female ninja suddenly grow a penis?
If you're after monsters like slimes I would not drop money on this.
I uploaded a photo of a pixel art electrician and it just completely ruins it and looks nothing like my guy and forces it into a particular style where it looks like a cheap mobile game playable ad and somehow Mario at the same time. Not to mention, the actual animation is wrong too.
This is a prototype, at best. I would be ashamed of asking money for providing such a sloppy service.
Also, in your faq you have "You own the rights to your generated content.", which I don't think is true. AFAIK, you can't copyright AI art.
The opposite is also true. Games that should never be made are being made due to the rubbish that can be generated by these tools. Observe the generated samples on the landing page, they are literally just copying street fighter. These tools are so useless without ripping off the hard work of humans. The deluge of slop is a signal to noise problem.
It definitely does solve a problem. This tool provides affordable custom sprites with fast delivery.
If it didn't solve any problem there would be zero demand for it and no reason for you to care about it.
Bet you $10 that in five years' time you will have.
I can’t ask a anyone that claims to be a pixel artist for sprites because the chance of getting garbage is just too high.
Btw, if anyone does know someone good, I’m open to paying xD
this is very obviously not true.
16x24 sprites end up looking a lot nicer though.
sorry for the long waiting, I didn't thought there would be so many requests. Added more powerful GPUs.
When your request finish it'll send you an email notification.
Don't really get the mean-spirited comments. Not everyone has the means to exascale their project.
Without them I am hesitant in uploading my concept art from my project for testing.
Otherwise it is a cool concept and I would potentially look in to if it turns out you don't go all evil villain and claim ownership over the sprites.
Enabling a preview set of sprites without having an account would do no harm neither.
But creating an account without any legal documentation is a no from me as I don't know whats happening with my IP which leaves me uncomfortable.
Even if it's not a ratified legal document; some draft is better than nothing.
People don't get paid for work that machines can do. It's not a novel concept.
It's been trained on some of the best artwork. Various artists have been told their artwork looks like AI, meanwhile it's actually the other around. Already in the app stores there are many games full of AI art that the average person without an artist's eye probably can't see the difference compared to something a human made.
I think art is very different from other jobs, it's more like the soul of humanity. When we look back through time, we mainly look at the art and what it can tell us, only a niche portion of people will care about the other things.
If we let machines do everything, even create our culture and art, what is left for us? Just to be consumers?
If the machine can do art that's indistinguishable from human art, and art is the soul of humanity, then the machine may have a soul? I've told the machine to create art, I've showed the art to humans, and the humans were touched by it. It evoked an emotion, like art is supposed to.
My personal anecdote: I've used a diffusion model to generate a short video based on a 50 year old photograph, the only photo my dear friend has of his late father that he never got to know. The 10-second video showed the man lifelike, happy and smiling, generated from a photo on which he looked morose. My friend was brought to tears when I showed it to him.
That's beautiful.
These tools will help people find more meaning in our short lives.
> People don't get paid for work that machines can do. It's not a novel concept.
Thank you! I'm sick of sounding like an apologist. This is simply the science of economics.
>> No shame in proudly presenting a tool with "putting people out of work" as a feature.
I am so tired of this type of attitude. I've read this endlessly and it does a whole lot of nothing for nobody.
This isn't putting anyone out of work. The games simply would not be made in the first place.
Someone might not pursue game dev because they can't build the art for it themselves. Now they have options.
>> Lovingly handcrafted artwork is what I like in video games [...]
Then you go buy that thing and stop dunking on people for making tools.
Give those artists you care about your money. Let the rest of us enjoy the new tools and the work created with them.
You don't weep for all the i18n experts when someone makes a nice open source datetime library. So stop doing it here.
Software engineers constantly have to learn new things and adapt. The artists will do the same.
If they actually start using the tools, maybe they can start making games and movies and things of a scale and scope they could never have done before.
The things you can accomplish with video models are downright impressive:

Someone told me, "But you didn't hire any hard-working stop motion animators."
Yes, that's right. Because it never would have been made before. Because stop motion animating a 4-minute Superman fandom short didn't make economic sense.
Does anyone else have any good recommendations?
https://streamable.com/k5iny8 (2day expiry)
Pretty much any character or animation.
I don't feel compelled to share unless anyone in the relevant industry wants to collab, in favor of supporting human artists.
Replace the people who actually contribute to society and no issues, but god forbid the pixel artist can't get paid to doodle anymore.
Most likely, more people will need medical attention.
You think in 20 years you have more doctors than today? Please.
Expert systems have been able to diagnose many illnesses better than doctors for decades but they have replaced precisely zero doctors for many reasons, but the biggest is that they can’t accept liability for their recommendations.
No company will ever release a consumer medical product that doesn’t tell 99% of patients they should check with their doctor.
Also do you have any idea how many times my wife has said something to friends and family like “no you don’t need to go to the ER, you can wait and if their fever doesn’t go away in X days see their pediatrician during normal hours. It’s likely a virus and nothing can be done anyway”, only to have that person take their child to the ER because they want a doctor to look at their kid and tell them face face that nothing is wrong.
A phone call with an expert they know isn’t enough to replace an in person visit. ChatGPT will never be enough.
As far as radiologists go, they haven’t been replaced yet despite people saying it would happen for years. And they are in a unique position where people never actually see them.
But even if all image reads are done with AI, they can always retrain as interventional radiologists.
Your wife's anecdotal info is a meaningless datapoint.
That was just to counter this statement.
It’s also not her anecdote, it’s based on data across her entire enormous group. None of the ERs they staff have seen drops.
But at the end of the day, you either accept it or pitch an alternative. What's the alternative? Freeze tech advancement at 2020's tech in your country? At what expense, and for what gain?
This is basically another "throw AI in it" CRUD app that wants your money. They're all really low effort grifts that do not deserve to see the light of day.
They work for a subset of animations that go in commonplace game types. Anything creative or new or different? No chance you'll get a satisfactory result. They are all subtly wrong in ways that anyone can easily spot and will likely get your game filtered out and harshly criticized publically on Steam or other platforms.
This right here too is so egregious: https://www.godmodeai.cloud/plans
