IndexOutOfRange

Hi, we are currently having the following problem with our script, and we don't know how to solve it.
Some help would be awesome since we believe is some very simple thing that we may be missing.

The exception thrown when executing the following script is the 'IndexOutOfRange' exception.when it tries to
run the following line: systems[0].transform.localEulerAngles.y < 5

My best guess is that the systems array, which is destined to be an array of GameObjects, has not been initialized. You can't read the length until it has been created. I think you need a start or awake function, which says like 'if ( systems == null){systems = new GameObect[20];}' or whatever... to set it up to exist. Then you can assign objects to it in the inspector or whatever.

 

Index out of range would suggest that there's nothing in the systems array, and you're trying to access an element that's empty.
Does the array that you're passing in through the inspector have any elements in it? Try logging the value of ax in your Start() function to see if the array is empty.
