[Solved][1.16.4] How do I correctly sync capability data between Client and server?

Recommended Posts

Okay, I believe I've done what you have told me, and my gui does update me gaining xp.


However, theres something wrong with my sync method, as whenever it is called, it resets all xp values to zero. So the values in my gui are lost when reloading the world.


Heres the sync method in my Skills class:

	public void sync(ServerPlayerEntity player) {
		if(entity instanceof ServerPlayerEntity) {
			PacketHandler.sendTo(new SkillsPacket(serializeNBT()), player);


Heres my attempt at syncing on login, in my player event handler:

	public static void onPlayerConnect(PlayerLoggedInEvent event) {
		ServerPlayerEntity player = (ServerPlayerEntity) event.getPlayer();
		if(!player.world.isRemote) {
			player.getCapability(SkillCapability.SKILL_CAP).ifPresent(c -> c.sync(player));


Updated my git repo, here.

I've changed the serializeNBT and deserialize methods so the value of i is in the key:

	public CompoundNBT serializeNBT() {
		CompoundNBT data = new CompoundNBT();
		for(int i = 0; i < 26; i++) {
			data.putInt("xp_" + i, (int) xp[i]);
			data.putInt("dynamic_" + i, dynamicLevels[i]);
			data.putInt("static_" + i, staticLevels[i]);
		return data;
	public void deserializeNBT(CompoundNBT data) {
		for(int i = 0; i < 26; i++) {
			xp[i] = data.getInt("xp_" + i);
			dynamicLevels[i] = data.getInt("dynamic_" + i);
			staticLevels[i] = data.getInt("static_" + i);


And now it works, thank you! (I think thats what the first person to reply to this post was trying to tell me to do but I didn't understand at the time).
