Support is not built in, but it should be easy to achieve using normal messages. If the array is small, you can just send it as JSON text (using the AsJSON expression). If it's large then that method will waste bandwidth, so you could instead have a message that is sent when individual indices change.
Thanks for the reply Ashely. Could you give me a step by step example of the method like how you would do it in construct. Would I use websocket?
1. The host has array.
2.Set as JSON text (using websocket?).
3.Sends to peers.
4.Peers update game with that JSON text?
