I see a couple problems: - ToList returns an object of Type List and you're attempting to assign it to a Transform[]. - ToList(Transform) should read ToList(transform) (get the instance name, not the type name) - Linq's ToList operates on the generic IEnumerable interface, which Transform does not implement (it implements the old-school IEnumerable). Linq does provide a function that'll fix this for you (code example below) This example is in C# because I am unsure of the generic argument syntax for javascript: List availablePositions = transform.Cast().ToList();
