Question by The_Toller · Oct 31, 2015 at 10:32 AM · c#if statement

Why is this if-statement returning true?

Hello! I have a really weird issue.

The following code is always printing the Debug.Log code. Even when distance is greater than range. Why is that if-statement always returning true? What am I missing? The Debug.Log always prints the distance and the range. If it is "1/10" that is correct since its below range. But it also prints "3242/10" if i stretch the objects apart. It's never false.

Thanks in advance for any help!

     private IEnumerator DoActions()
     {
         float distance;
         while(target)
         {
             distance = Vector3.Distance(transform.position, target.transform.position);
             if(distance < range);
             {
                 Debug.Log (distance + "/" + range);
                 //Do things
             }
             yield return null;
         }
     }

Here:

 if(distance < range); <-----

you have a semicolon after your if. That will terminate it at the same line. So the following block doesn't belong to the if statement at all. Just remove that semicolon ^^.
