How to create a chasing enemy that only follows the player in its line of sight in Unity (2D)?

Question

Game development

I created the enemy itself, that is, it pursues the player, but indefinitely. And I need him to pursue the player only in his line of sight. That is, when the player comes out of there, the enemy stops.

Answer 1

I assume that you have a banal pull-up along the coordinates behind the player. In this case, it's school geometry, you just need to ignore the player when he is outside the desired zone.
