[1.12.2] Prevent client side changing of server configs

[Tomson124]

Recently I realized that if you change the config values of my mod (SimplyJetpacks 2), this changes also the values for the jetpacks on servers. The server configs are not changed as far as I know but it seems that always the client configs are loaded. Is there a way to change this, so it loads the config from the server, when the player is on a server?

You should treat singleplayer and multiplayer exactly the same. As soon as a player logs in, send them the necessary config data using a packet (server-side). Then on the client store those values separate from the "actual config values". On the client you then only access those separate values.

I changed the side of the ConfigSync from Client to Server, but I guess that is not enough, right?

public static void init() {
		SimplyJetpacks.logger.info("Registering network messages");
		instance.registerMessage(MessageJetpackSync.class, MessageJetpackSync.class, 0, Side.CLIENT);
		instance.registerMessage(MessageConfigSync.class, MessageConfigSync.class, 1, Side.SERVER);
		instance.registerMessage(MessageKeyboardSync.class, MessageKeyboardSync.class, 2, Side.SERVER);
		instance.registerMessage(MessageKeyBind.class, MessageKeyBind.class, 4, Side.SERVER);
}

Yeah I did, I am sorry but it is the first time that I have to deal with the client/server side interaction on my own. The current Config is read from the File and then parsed to the NBT. From there is will be read on item init to set the NBT values for each item.

I guess I have to get the file on the server side an then write it to the NBT (or a variable) and get it from there on the client side for item init.
