#1

I’m making a game where all characters are made out of sprite sheet, to make the sprite sheet, it would took me around a month or two to finish the animation. is there any AI tool that can help me generate animation fast? Or is the best tool or AI tool that can generate it?

Thank you so much in advance for the responses.

For sprites I usually get them from https://www.gamedeveloperstudio.com/
They have a nice style and are very easy to implement in Solar2D projects with texturepacker.

I have practically used these sprites in all of my projects.
