Errors appear when i get a bad Raycast hit. Meaning when it hits another object in the scene.
The error happens on line 57 at random with no rhyme or reason.
I have multiple empty game objects with this script attached to each object separately.
The script works and shows when a good or bad hit is received So i dont know why the error is showing if the debug is getting through. Im getting between 3 to 6 errors of the same type.
NullReferenceException: Object reference not set to an instance of an object RandomizeObj.Start () (at Assets/Scripts/RandomizeObj.cs:57)
All objects are tagged correctly and and the RayCast is a successful hit.
I should mention thta it was working fine untill i added these four conditions to the while loop.
(hit.collider.gameObject.tag == "Roads") || (hit.collider.gameObject.tag == "Debris") || (hit.collider.gameObject.tag == "Pickup") || (hit.collider.gameObject.tag == "Buildings")
Once again spelling is correct and the tags match. Also when i look in hierarchy and select a generated object i can see that the tag is assigned.
The while loop is to ensure that a new object does not fall on something that is placed in the scene already.
