[1.6.4] Method Called on Tile Entity Creation

[superninjaman45]

Is there a method that is called when a tile entity is created. Well perhaps that is not exactly what I need to know. I need to assign a variable in the tile entity when it is created and only when it is created. It involves random numbers so i can't have it  being called constantly, only once. I hope that this isn't a dumb question. Thanks for your time. And sorry if this is not specific enough. Thanks

[superninjaman45]

Sorry. Just figured it out anyway. Shouldn't have posted. Thanks for replying though.

Edit:

Actually my troubles aren't over. Nothing is printed to the GUI. Well, if anything is, its blank anyway. I am swallowing a bit of pride here and I am going to post my code. Sigh. Any way you can help without telling me just to figure it out would be appreciated.

Yes the GUI is registered. And it does print things if I need it to.

I did trying using world.getBlockTileEntity(x,y,z) The files were a lot different then so don't trying looking for it in them now. However I had the same problem.  Nothing would show up. Here is that older code.

Also, I'm not expecting magic. Did you read all the code? I thought it looked reasonable.

   public BlockVillage(int par1) {

A block is only created once in the entire game. You should decide the name when the block is placed.

You have only 8 town names, you could use metadata and change the meta values.

[superninjaman45]

Ah, that makes sense! Thank you! Though I am not going to use metadata, the tile entity will have a lot more later, this is just a test. Its still not showing up on my GUI which is strange. See anything else?

[superninjaman45]

I believe I found the problem.  The part

 if(!var1.getString("Village Name").isEmpty())
    {
    System.out.print("1");
	this.TownName = var1.getString("Village Name");
	}
    

runs even if the value of var1 is empty. Not sure why that is.  I'll try something slightly different there.

[GotoLink]

Probably because you are returned a default string if there is none.

You should use hasKey(String) instead.
