Using Gui to Tame Entities

[prime17]

I'm trying to tame an entity using a Gui I made. It works at first when I play Minecraft and tame the entity but when I restart Minecraft the entity is no longer tamed. How can I fix this?

 

EntityTitan code

public boolean allyTitan(EntityPlayer player)

	{

		this.setTamed(true);

		this.setPathToEntity((PathEntity)null);

        this.setAttackTarget((EntityLivingBase)null);

        this.aiSit.setSitting(true);

        this.setEntityHealth(20);

        this.setOwner(player.username);

        this.playTameEffect(true);

        this.worldObj.setEntityState(this, (byte)7);

        this.worldObj.setEntityState(this, (byte)18);

        return true;

        

	}



	public boolean followPlayer()

	{

		 this.aiSit.setSitting(!this.isSitting());

         this.isJumping = false;

         this.setPathToEntity((PathEntity)null);

		return true;

	}


	public boolean interact(EntityPlayer player)

    {	

	super.interact(player);

		player.openGui(mod_POTE.instance, 3, worldObj, (int)posX, (int)posY, (int)posZ);

		return true;

    }

Firstly, if it's working when you play normally but not when you restart, then you need to make sure that your entity is reading and writing all the proper data from / to NBT. Secondly, since you are changing things from within a GUI, you need to send packets informing the server of each change so the correct data can be stored.
