How to get server side capabilities and config from client?

[GThoro 0]

Hello, I've attached some capabilities to players on server side, but I need that data to display in GUI. I know I'm supposed to sync it to client but it's a bit vague. Can someone give me few pointers or examples? I'm able to put all needed data in extraDataWriter while using NetworkHooks.openGui but I need to write another serializer/deserializer for capability data. Does syncing capability data allows me to skip that?

 

Also in the same GUI I need some config values that are set server-side, how can I access that? Is there a way to sync configs, or I need to use extraDataWriter for this?

No. "Syncing" describes exactly this process of sending some kind of network packet (that is what NetworkHooks.openGui does under the hood) containing the capability data.

The extraDataWriter is the perfect place. There is no need to send the data previously (if the GUI is not open yet), it's just unnecessary network traffic.

I see, I thought there is some magic way to call player.getCapability() on client side and get the same results as on server side. Thanks, I know what to do now.

No, there is no such thing as magic in programming.

"magic", not magic.

One more thing if I may ask. If I need to perfrom some action on that server side capabilities depending on user interaction in GUI, I need to send packet with message from client to server?

Correct.

Just beware: You must treat the client as a lying bastard. Always verify everything and assume the client is trying to cheat.
