Notification
Since v0.2-beta
Why use the notification system provided by MessageChain?
It might be not so useful,
but I think it would be better to use different methods to process different messages,
Instead of putting them altogether by invoking ServerPlayNetworking and ClientPlayNetworking.
It will definitely improve code readability.
There might be moments when you want to push something to players, so we built a simple notification system.
Process
In short, refer to this link to view the example source code.
Client-side notification receiver registration
In NotificationManager, use the following method to register a notification receiver:
NotificationManager.getInstance().registerHandler(Identifier, AbstractNotificationHandler, boolean);
The last parameter indicates whether the notification receiver should be removed once it had been invoked.
Be aware that the receiver will run on the main thread instead of creating a new thread, and you have no other options so far.
Server-side notification push
On server-side, use the following method to push a notification:
NotificationManager.getInstance().sendNotification(Identifier, TPayload, ServerPlayerEntity);
The receiver must be a game client.
There will be a method to broadcast notification in future version (maybe in v0.3-beta).
Remove an existing notification handler
To remove an existing notification handler, use the following method:
NotificationManager.getInstance().unregisterHandler(Identifier);
