A lot of my sprites are randomly scaled -+ 0.2 to make the game seem more dynamic, but the OCD in me gets uncomfortable seeing the differing outline widths. With 50+ of these objects being on the screen at the same time, is it worth it performance wise to add outlines dynamically and what technique would you use?
If you are wanting a uniform outline over everything I’d look into Edge Detection Image Effects. That should be what you’re looking for. Now whether the ones you find online work with sprites i’m not sure.
