Unity 2D - pixel art sprites ripple when rotated, how to solve the problem?

Question

C++ / C#

the image shows that when the sprite is rotated, its edges seem to "ripple", how to solve this? I want the lines to stay straight when turning, without ripples. Waiting for answers, help!

Answer 1

How do you think a line at 30 or 45 degrees on a piece of paper should be drawn not with "steps"?
add slightly translucent pixels - so that it doesn't look so "staggered". actually anti aliasing in the quality settings is what it does.
well, or the resolution of the screen / cells is super small compared to the line thickness.
