Make Enemy follow and rotate towards target in Unity

///We shall make the enemy follow the target and then we will make the enemy flip when the target set comes behind the enemy along the x axis
///You can use this script to make an enemy follow the player or to make an object flip towards an object
//For this script to work, you must assign a game object in Unity in the followTarget field.

//Declare Variables

public bool _facingRight = false;

        //Compares the target and the object transform and flips in the direction towards the position that the setTarget is currently at.
