      • Hi all, I am trying this method, but with an arraylist that contains Vector3 data types, I don't know how to find a particular one. I tried: Console.WriteLine ( "IndexOf Vector3: {0}", a.IndexOf ( new Vector3 ( 0, 0, 1 ) ) ); But this returns -1, even though there is a Vector3 ( 0, 0, 1 ) in the arraylist. Any idea on how to solve this Thanks, Aw
