Question by jj-jhow · Jul 12, 2020 at 06:48 PM · booleanserializefield

How to link two serialized booleans?

How can I make sure that if one serialized boolean field is made true (in the unity inspector) the other gets unchecked? I specifically need to say that they are either Start, End or none at all. So I need 3 options, it's not a case of either being Start or End (that's not that hard, now is it? :D ) I have the following so far and am using a Debug.LogError and Error Pause in the console for testing in case I get case where both isWaypointStart and isWaypointEnd are true. Not ideal but hopefully someone can shed some light. Thanks!

 [SerializeField] public bool isWaypointStart = false;
 [SerializeField] public bool isWaypointEnd = false;
 
 void Awake()
     {
         if (isWaypointStart && isWaypointEnd)
         {
             Debug.LogError("you cannot have " + this.name + " be both the start and finish waypoints at the same time.");
         }
     }

Giving the opportunity to make a mistake rather strange decision. Just make an enum:

 public enum E_Waypoint
 {
     None,
     Start,
     End
 }

Can rename None to your liking like Path or whatever. Or keep it and just add fourth for Path and use default None for errors. And field for it:

 public E_Waypoint waypoint;
