Strange Raycast Problem

Questions & Answers
1

I am trying to make a hexagonal movement system like in for the king, so I am casting a ray into the direction of my target until it hits another hexagon, but my while loop won’t run because unity says that my RaycastHit hitTwo does not have a value. Shouldn’t it work even if hitTwo is null?

FYI targetHex is the gameObject that I want to travel to, layermask is my layermask, currentHex is the gameObject that I am currently at, and otherRay is my ray.

My code:

while (hitTwo.collider.gameObject != targetHex) {
      if (Physics.Raycast(otherRay, out hitTwo, float.MaxValue, layermask)) {
              currentHex = hitTwo.collider.gameObject;
              otherRay = new Ray(currentHex.transform.position, targetHex.transform.position);
              print("found");
      }
}

I assume that you have defined hitTwo before this, so that is not the the issue.
I think the issues that yes while “while(hitTwo != targetHex)” it would work if it was null. However, I do not think that you can use .collider.gameObject on null.
