I was actually thinking about sprite sheets last week (like I said, I am exploring what it means to work with asset animations).
The hypothesis that we have so far is: those who buy sprites online will get pre-made sprite sheets (CupNooble’s example found on the web)
And those who create their own art export frame by frame (since they animate frame by frame). -Which the app handles at the moment-.
When I produced animated art for video games I exported them frame by frame, but the developper used a solution to create sprite sheets to improve performance (we were making educational video games optimised for limited technologies).
Therefore, importing a sprite sheet even when the art has been made custom is a possibility too? (I need more data from user’s experience on this). If it does improve performance, might be another question…
If we get enough user input and the feature makes it to development, the engineers would have to think of a technical solution to evenly cut a sprite sheet (since not every element has the same size).
As Silver said, working with sprite boundaries is tricky because getting one extra pixel on the frame cut would mess the whole animation (thanks Silver-Streak for the documentation!).
I’ll keep an eye on this conversation to read future comments on the matter.
