In this Unity tutorial we're going to look at how to detect whether game objects are on screen or not.

We’ll make sure that the player is blocked from leaving the screen bounds.

If the enemies wander off screen, we’ll make them wander back into view.

And when the bullets leave the screen, we’ll destroy them.

This is the ninth video in our series showing how to make a full top down 2D shooter game in Unity.
