Making RB movement smoother/curvy. C#.
Hello. I am trying to make my rb movement more smooth/ curvy, rite now it only moves with rough edges when changing move direction.
Current movement

Hi @matejaizverieas
what you are looking for is called interpolation, there are multiple possible solutions.
One that is really awesome and fast is called "Bezier Curves", you can find good tutorials here and here
