WOW! this is an insane amount of art and I'm sure it will be tremendously useful to a lot of people. No idea how I'm going to comb through this but I can't wait! Thank you so much for this contribution.

Wooph.  This is amazing.. possibly one of the best finds for OGA.  Hopefully we can regroup some of this for easier viewing... almost need someone to take a full time job on making sprite sheets..

This is extremely awesome, but could you please provide a preview sheet? It would be helpful and also at the first glance it only looks like a single sprite now.

Thank you :)

that's a good idea. I could add a preview sheet if anyone is willing to create one. :)

Let me see :)

Here, I hand-picked some sprites. It was very difficult, the collection is huge and full of awesome image :)

Hi, I realize these are released under the public domain, but I still want to ask for permission to include some of these icons in the AnyRPG Engine.

It's an open source RPG Engine released into the public domain via an MIT license at https://github.com/michaelday008/AnyRPGAlphaCode.

I will be submitting it to the Unity Asset Store soon.

I need to ask permission because Unity has strict rules about not including content that is part of another package available on the store, so if you were to post these on the asset store, I wouldn't be able to directly include them in the AnyRPG package.

If I can include your work, please let me know what type of attribution you would like and provide the name and URL (if any) I should use. I can offer all of the following:
-In engine credits link
-YouTube featured channel link (if you have a channel)
-anyrpg.org Contributors link

You're welcome to use these assets however you wish. If you're asking for exclusivity, that's not going to happen; anyone (including you) could submit these to the asset store any time they want. If that's against unity's rules, you'll need to ask them for special permission, not us.

From what I understand, the rule is to prevent people from just downloading 5 or 10 packages and then re-posting them as a compilation, which redirects traffic/reviews/etc away from the original author.

I just wanted to make sure the original author didn't plan to post the entire set on the Asset Store as a single package.

As long as that's the case, then anyone could probably use as much of this in their projects as they wanted, even if their was some overlap, because no one is taking views or downloads away from the original author.

My plan right now is to use up to 100 of these for various random inventory icons.

Thanks for confirming I can include those in the Unity Package.

Sure. Happy to help.

However, please do not spam various submission pages with this request. My response above applies to every CC0 submission on this site. If searching the unity store to see if someone else already uploaded them is not a sufficient precaution, you either need to talk to Unity or don't upload the assets by themselves.

Sending authors private messages is a good way to get specifics about how they would like their works to be used and attributed, but you should not expect a response. At least not a prompt one. Many authors only check in every few months, some even longer, and some may choose not to respond at all since they feel they have given all the permission needed by way of sharing the assets here under an open license. Usually though, authors welcome comments about their assets being used in your projects. :)
