[1.19.2] ServerSide to ClientSide Open Screen with capability

[FantaLaTone]

I have a capability called NPCTrades and a screen class called NPCScreen.

This is the current packet I am using to handle opening screen: https://gist.github.com/fantalatone/65116264037b83955a99c8c014d328ef 

But with this packet I can't set the hashmap in the constructor method of NPCScreen class (https://gist.github.com/fantalatone/8d309e1c6bcc86a2f5ba92c707a78f4e)

How I can send capability data to a screen class?

The same way you send other data to the client through a packet? You can send it in the packet you are currently handling.

I tried sending the OpenScreen packet from a custom command but it didn't worked

Let's look at this section. In the constructor, you read the key and value of the map, so it's expected that you write the key and value as well. In the method, you write the key, but then you print the byte buf and the value instead of writing the value.

Alright, so should I write the writeMap() method again under the first one?

[ChampionAsh5357]

You should write the value, you are already writing the map, albeit partially.

I did a lot of changes. Now all I need to do sync the HashMap data from server to client. I am using menus now. How I can sync the hashmap?

Same way as you did in the packet, fixing the issue where you don't write the value. You will need to use IContainerFactory now for the menu though.
