DoWhile Loop is crashing Unity. Why?
The do while loop within the following script crashes Unity every time I try to run the scene. If I take the loop out of this script it runs fine, but with it in, Unity just freezes when I hit play. Any idea why?
using UnityEngine;
using System.Collections;
public class FloorDistance : MonoBehaviour {
public GameObject characterPos;
public GameObject floorPos;
Vector3 posChar;
Vector3 posFloor;
public float distance;
void Awake ()
{
posChar = characterPos.transform.position;
posFloor = floorPos.transform.position;
}
void Update()
{
do
{
distance = Vector3.Distance(posChar, posFloor);
} while(distance > 0f);
Debug.Log(distance);
}
}
Best Answer
Vector3.Distance(posChar, posFloor) does not change within your loop. Thus if it's > 0f, the loop will go on forever.
Ah, thanks. How do I make it change? posChar is assigned to a character that can move around the scene and posFloor is assigned to a static object. I want to update the float "distance" with the distance between the two objects as I move the character around.
distance will never be more than 0, it will never change from what it is currently when the loop starts.
