[1.9.4] Syncing Player Capabilities


Recommended Posts

The line where I sync the code (in the 1st code excerpt below) it returns a null error.


Attach Event:

public void attachCapabilities(AttachCapabilitiesEvent.Entity e) {
	net.minecraft.entity.Entity et = e.getEntity();

	if(!et.worldObj.isRemote && et instanceof EntityPlayer) {
		e.addCapability(new ResourceLocation(Scalae.MODID, "IScalaeCapability"), new ICapabilitySerializable<NBTTagCompound>() {
			IScalaeCapability instance = Scalae.CAPABILITY.getDefaultInstance();

			public boolean hasCapability(Capability<?> capability, EnumFacing facing) {
				return capability == Scalae.CAPABILITY;

			public <T> T getCapability(Capability<T> capability, EnumFacing facing) {
				return capability == Scalae.CAPABILITY ? Scalae.CAPABILITY.<T> cast(instance) : null;

			public NBTTagCompound serializeNBT() {
				return (NBTTagCompound) Scalae.CAPABILITY.getStorage().writeNBT(Scalae.CAPABILITY, instance, null);

			public void deserializeNBT(NBTTagCompound nbt) {
				Scalae.CAPABILITY.getStorage().readNBT(Scalae.CAPABILITY, instance, null, nbt);

		ScalaeCapabilities.getStats((EntityPlayerMP) et).sync();


Here's the get method:

public static PlayerStats getStats(EntityPlayer p) {
	if(!p.worldObj.isRemote) {
		final IScalaeCapability cap = p.getCapability(Scalae.CAPABILITY, null);

		if(cap != null) {
			return cap.getStats().setPlayer(p);

	return null;


And the sync method:

public void sync() { //Located in PlayerStats.class, has a player field
	if(player != null) {
		Scalae.network.sendTo(new MessageSync(this), (EntityPlayerMP) player);


I have a message class that can be sent from the client to the server for a request to sync data, but I can't find a good event to place it in client-side.

AttachCapabilitiesEvent.Entity is fired directly after EntityConstructingEvent which bascially means - there is NOTHING to sync (example: entity can be constructed with "new", but that doesn't mean it is spawned to world or has its equivalent on client).


Syncing should happen from EntityJoinedWorldEvent. (Attach event is ONLY for attaching, not getting/modifying/syncing).

1.7.10 is no longer supported by forge, you are on your own.

    • Exception in thread "main" java.lang.IllegalStateException: Current Java is 1.8.0_271 but we require at least 17         at net.minecraftforge.bootstrap.shim.Main.main(Main.java:32) Never have successfully gotten a minecraft server up and running so I thought i'd try again. Instant unfixable issue.  
    • What MC version? What's the IP? Are any mods needed to be able to join?
    • Thank you for your answer ! Unfortunatly i have the same problem when i use setPos() public static int movingfunction(CommandContext<CommandSourceStack> context){ CommandSourceStack source = context.getSource(); if (!(source.getEntity() instanceof ServerPlayer)) { return 0; } ServerPlayer player = (ServerPlayer ) source.getEntity(); double moveSpeed = 0.5; for (int i =0; i<10000;i++) { LOGGER.info("running for the {} time", i); double x = player.getX() + player.getViewVector(1.0f).x * moveSpeed; double y = player.getY(); double z = player.getZ() + player.getViewVector(1.0f).z * moveSpeed ; Vec3 movementVec = new Vec3(x, y, z); LOGGER.info("x ={} y ={} z ={}", x, y, z); player.setPos( movementVec); } return 1; } With the logs i can see that x and z are increasing but once again my player is not moving. is there a function to use to sync the server and the client ? I also tried to use LocalPlayer instead of ServerPlayer but my code would stop when i got the object. Also i will change a bit the main topic but is there a way to similate key press ? i found KeyBinding.setKeyBindState on others post but it look like there is no more KeyBinding in 1.20   I found this code : KeyMapping.click(Minecraft.getInstance().options.keyUp.getKey()); But it doesn't seems to work   And i found this one : Minecraft.getInstance().options.keyUp.setDown(true); wich works but doesn't exactly do what i want , it doesn't release the key so for exemple i can't make him run. Minecraft.getInstance().options.keyUp.setDown(true); Minecraft.getInstance().options.keyUp.setDown(false); Minecraft.getInstance().options.keyUp.setDown(true); doesn't make him run
