Attempting to set bool on targeted object - if target is set to true, move to next in list.

So in short, i am attempting to have the below script "target" a game object(it does this fine), and move towards it, however if the enemy has "AmITargeted" set to true, it will search for a new target.

However i would like to have multiple enemies on screen, and once a enemy has been targeted, the "AmITargeted" bool on the enemy is set to true.

as an example. Team 1 has two units. (labelled A & B) The enemy team(team 2) has two units also (Labelled C &D)

Unit A starts - targets unit D - Sets unit D's AmITargeted to true. Unit B starts - Targets unit D - sees that unit D's AmITargeted is true, and then targets unit C.

any help would be great! here is the code for the "ally units" the enemy units will be carbon copies of this. using UnityEngine; using System.Collections; using System.Collections.Generic;
