Private Variable To each block of same type

[pollitoyeye]

I´ve created a block and I dont know how to make thath if I put two blocks of this type both have independent variables and when clossing the game, both variables get saved to load them again when loading the world.

At the moment I have this code:

public class block2 extends Block {
private int i = 0;
public block2(int id, Material Material) {
	super(id, Material);
}
public boolean onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer, int par6, float par7, float par8, float par9)
{
if (!par1World.isRemote)
{
    this.i = (this.i) + 1;
	par5EntityPlayer.addChatMessage("Numero de banderas obtenidas hasta el momento: " + i);
return true;
}
return false;
}
}

The variable I want to do is i

Hi

 

The important to remember is that there is only one of each Block.  You don't get a block2 for every block [x,y,z] location in the world, there is only one block2.

 

There are two ways to store unique information for every block location:

(1) If you only need to store up to 16 different numbers, you can use block metadata.

(2) If you need more than 16 different numbers, use TileEntity.

 

A quick search on the forge tutorials will show you examples of how to use each one.

I need to use more than 16 but the link doesnt works for me

Tile Entities are real easy.

 

Change your existing class to extend BlockContainer rather than block, Eclipse will throw an error, just hover over it and take the suggested action ("add unimplemented methods").  We'll come back to this function in a minute.

 

Create a new class, make it extend TileEntity.  This is where the bulk of your block's code will go.  The TE will handle everything, the "block" is just sort of an anchor.  You'll want to take a look at the base TE class to see what methods it has by default, use what you need.

 

Go back to your block class and in that new method that was created, change it from "return null" to make it return a new instance of your TE.  (return new myTileEntity()).

(Some of those are mobs, I use the same package for both just because I never have very many of either)

You can also specify a custom renderer if you need it, either an ISimpleBlockRenderingHandler (which is basically the standard cube renderer) or a TileEntitySpecialRenderer (for model based types).  I wouldn't suggest looking at either in my code, the ISimpleBlockRenderingHandler I have is super complex and completely unnecessary for anything you'd be doing and you'd really want a basic Techne tutorial for models.
