Question by Pysassin · Mar 20, 2013 at 07:25 PM · array index

Could you help me with Array.RemoveAt()?

I have an array I am finding the index to and then removing the item at the index. I have a custom function that finds the index of an item in the array. This is working fine (used console prints to test it). The index is a valid index number AND is the object I want, however when I go to Array.RemoveAt(index) I get an OutOfRange error.

The function that is causing errors is....

 function AddBrokenConnection(broke : GameObject, temp : GameObject){
         var brokeIndex : int;
         brokeIndex = FindIndex(broke,realConnections);
         if(brokeIndex != -1){
             realConnections.RemoveAt(brokeIndex);
         }
         brokenConnections.Add(broke);
         tempConnections.Add(temp);
     }

FindIndex is the function that finds the index. It returns -1 if the function can't find it in the array. The array length returns as 2. The index number I am removing is 1. So I fail to see why it is throwing errors.

I see nothing obviously wrong with the code. Sometimes when I have errors like this I find I've attached the script to more than one object, and it is the unknown component attached that is throwing the error.

You will save yourself a huge amount of grief if you never use Array, and always use a generic List ins$$anonymous$$d. You wouldn't need to bother with any of this, but could just remove the GameObject directly. e.g., assu$$anonymous$$g you have a List.< GameObject > called "goList", then just do goList.Remove(myGameObject). Plus you have built-in functions for getting item indices (namely IndexOf) if you ever do need the index.
