Feedback for “State View”

[wenshizhizi]

Hi there, I'm encountering an issue while using the Colyseus framework. In my custom schema, there's an ArraySchema field marked as private, so I used the @view decorator and created a StateView for the client upon joining the room, adding this field. The problem occurs when I perform a push() operation on this ArraySchema - the client doesn't receive updates. After reviewing the documentation about view features at https://docs.colyseus.io/state/view, I noticed that for ArraySchema, each item needs to be individually added to the client's StateView. I modified my code to:

typescript
view.remove(player.gameData.cards);
view.add(player.gameData.cards);

This change made the client properly receive updates. My question is: since this field will frequently have additions and deletions, do I need to rebind it like this after every operation? Or is there a possibility that ArraySchema might be optimized in future versions? This is very important for me. Thank you so much for your help!

Hi @wenshizhizi, I agree sometimes an entire collection of items should be automatically added to the client's view. We would possibly need a different tag than @view() for such cases. Or maybe a different type signature for @view() that makes this use case possible. Suggestions are very welcome!
