iOS forces you to use pretty animations: if you don’t tell it otherwise, it will use “ease-in/ease-out” curves to make things feel … smoother, less jerky.
Unity is made for programmers; changes you make to position, size, rotation, etc all happen instantaneously. By default, they won’t even animate, will teleport instead.
So … moving from “prototype with no animation” to “prototype that won’t hurt people’s eyes, and I can share”, what are some tips and gotchas?
