Unity 2d - stop sprite from leaving the screen

Questions & Answers
1

I’m making an Android 2D up to down game and want to avoid the object from leaving the screen. The problem is that the screen size changes between phones, so if I try to use colliders at the limits of the screen, if the resolution changes, the colliders will end either inside the screen or outside. Is there an easy way to achieve what I want?

You can use Mathf.Clamp to restrict movement.
