Hi,
yes, ArrayMaker is still a solution of choice for more advanced use of arrays. and if you are concerned about performances, simply get in touch with me and we'll look at it, but indeed as Graham said, you can expect ArryMaker to deliver.
Where built arrays is more performant is when the number of items in the array doesn't change, then built in array performs better ( in theory, because on practice it's aonly after thousands of items that you will have a noticeable impact), everytimw you need to add and delete items in your game and often, ArryMaker is far more suitable because it's using dedicated lists that are meant to be flexible and if you try to do this with built in array you' have performances impact far quicker then the other way around.
also, ArrayMaker has more flexible inspectors to browse long lists of items, which helps when you have lots of data to deal with.
Bye,
Jean
