Keeping the player to be within the screen

Unity Engine
1

Hi!

Mine is 2D app.
The player moves only up and down.
The screen has a ground sprite. Its height is 300 pixels(0.3f).

I want to keep this player to be within the screen, because it flies out of the upper border of the screen.
The script for this as follows;

…

public class Boundary: Monobehaviour
{

just make a 2d collider at each side of the map.

Here is a great tut on that and also covers many other 2d things you may come across.

Hi, Kobaltic1

Much appreciation for your help.

You mean that a 2d collider must be set up along the upper borderline of the screen?
There is no any simple script to resolve this headache?
