Hello Everyone.

 

So I have been experiencing some lag issues with my mod, and have tracked it down to my cables constantly updating their connections and block bounds every tick (I was doing this in updateEntity()) So what I have done, is in the block class, I have changed it to update in onNeighborBlockChange(...). Now with this, when I reload the world, all the connections are gone, and each cable has to be updated. So my question is how can I write a ForgeDirection array to NBT?

You can save the ordinals of it using (for example)

ForgeDirection#ordinal()

.

So would this work?

 

        public ForgeDirection[] connections = new ForgeDirection[6]; //This is the array that stores the connected sides.

        //Some irrelevant code here...

        public void readFromNBT(NBTTagCompound nbt) {
	super.readFromNBT(nbt);

	for (int i = 0; i < connections.length; i++) {
		this.connections[i] = nbt.getInteger("connections_" + i);
	}
}

public void writeToNBT(NBTTagCompound nbt) {
	super.writeToNBT(nbt);

	for (int i = 0; i < connections.length; i++) {
		nbt.setInteger("connections_" + i, connections[i].ordinal());
	}
}

        @Override
public Packet getDescriptionPacket() {
	NBTTagCompound tag = new NBTTagCompound();
	this.writeToNBT(tag);
	return new S35PacketUpdateTileEntity(xCoord, yCoord, zCoord, 1, tag);
}

@Override
public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity packet) {
	this.readFromNBT(packet.func_148857_g());
}

This:

public void readFromNBT(NBTTagCompound nbt) {
	super.readFromNBT(nbt);

	for (int i = 0; i < connections.length; i++) {
		this.connections[i] =ForgeDirection.getOrientation( nbt.getInteger("connections_" + i));
	}
}

Okay, thanks, it is working fine now
