[1.10.2] Can I have some help with NBT

[American2050]

For some reason NBT is one of the things I always seam to have problems with, I probably always confuse with what the methods do and mess them and never get clear how to use them.

 

In this case, I'm messing with the Pigs, I know they have some information on them, like for example, if they are equipped with a Saddle or not.

 

As for now I'm just reading it and printing on console, just to make sure I get it right.

 

//I comment the code to see if I clear myself what each line of code it doing

 

//Create and NBTTag to hold the information stored (Why isn't this loaded already with the Pig info that already exists? or is it?)
					 NBTTagCompound pigData = theEntity.getEntityData();

					 //Write into the NBT that we created the info on the pig (Is this really necesary?)
					 ((EntityPig)theEntity).writeEntityToNBT(pigData);

					 //Set a new tag "pigInfo" (This is a String) with my data, in this case a TIMER that is an int.
					 pigData.setInteger(pigInfo, TIMER);

					 //Store the modified NBT that now contains my data back into the entity
					 ((EntityPig)theEntity).readEntityFromNBT(pigData);


					 //Now from this and below, just to print the values out and see they working

					 //Again create an NBT (Maybe this step here isn't needed at all right? we have already pigData created above
					 pigData = theEntity.getEntityData();

					 //Read the pig info into the NBT
					 ((EntityPig)theEntity).writeEntityToNBT(pigData);

					 //Print out the Vanilla data and the one added by me
					 System.out.println(pigData.getInteger(pigInfo));
					 System.out.println(pigData.getBoolean("Saddle"));

 

Am I doing it correctly, am I doing extra steps that are not needed?

 

Thanks a lot. Hopefully some day I wont have any problems with NBT anymore.

Where are you calling this code?

[American2050]

I'm calling it on an event:

 

@SubscribeEvent
 public void onEntityTick(LivingEvent event)

 

After checking all this is meet:

 

Entity theEntity = event.getEntity();
	 World theWorld = theEntity.worldObj;
	 BlockPos thePosition = new BlockPos(theEntity.posX, theEntity.posY, theEntity.posZ);

	 if(!theWorld.isRemote){

		 if(theEntity!=null && theEntity instanceof EntityPig){

			 if(theEntity.hasCustomName()){

				 if(Utilities.isValidPigName(theEntity.getCustomNameTag()))
				 {

 

So basically any Pig in game named certain names will call this code (As for now it's setting the value over and over, I know, but once I know I'm doing it right, I will check all this in my TODO list:

 

//CHECK IF THE ENTITY ALREADY HAS OUR TIMER AND IF IT REACHED 0

 

 

//ENTITY DOESNT HAS OUR TIMER - LETS CREATE IT

 

 

//ENTITY HAS OUR TIMER BUT IT DIDNT REACH 0 LESS DECREASE TIMER

This has nothing to do with NBT. Nothing.

 

To check if a pig is saddled, call

EntityPig::getSaddled

. It will return true if the pig is wearing a saddle. What other information are you trying to get?

Isn't the information about having a saddle stored on a Pig saved on an NBT in the entity?

 

Please read the original post again, I guess you missed what the point was, I just mention the Saddle as an example of what's already on the NBT and how do I add my custom information into it.

 

The important part here is that Im adding more info into the NBT

 

//Set a new tag "pigInfo" (This is a String) with my data, in this case a TIMER that is an int.

pigData.setInteger(pigInfo, TIMER);

Isn't the information about having a saddle stored on a Pig saved on an NBT in the entity?

 

No.  It's stored in the entity's fields.

[American2050]

NBT is for saving to disk.

If you want to attach additional data onto entities that are not yours use Capabilities.

 

Thanks, gonna take a look into this

 

From what I was reading I will probably need to create my own also. Hopefully I can get it going, otherway I will ask.

 

Thanks once again
