Tile Entitys

Can anyone tell me how to make this Tile Entity work? I've tried everything, but still the stupid thing returns null...

TileEntityPower.java

Code:: package net.minecraft.src;

public class TileEntityPower extends TileEntity
{

public int level;

public TileEntityPower()
{
level = 0;
}

public void writeToNBT(NBTTagCompound nbttagcompound)
{
super.writeToNBT(nbttagcompound);
nbttagcompound.setInteger("level", level);
}

public void readFromNBT(NBTTagCompound nbttagcompound)
{
super.readFromNBT(nbttagcompound);
level = nbttagcompound.getInteger("level");
if(level < 0)
{
level = 0;
}
}

public void changePower(int power)
{
level = level + power;
onInventoryChanged();
}
}

Code:: created by:
world.setBlockTileEntity(i, j, k, new TileEntityPower());

referenced by:
TileEntityPower power = (TileEntityPower)world.getBlockTileEntity(i, j, k);
int l = power.level;

Mod file has
ModLoader.RegisterTileEntity(TileEntityPower.class, "power");
in load()

I have no clue... Obviously missing something

I'm looking into this, I don't have a lot of experience with the tile entities, will have to dig around a bit.

Just out of curiosity what is referencing the entity and initializing the int l variable to set the power?

I'd have to see how the whole thing works to wrap my head around it.

I'm going to go take a look at the MC entities and see if I can speed learn how they're laid out.

I'm not sure. It looks right to me...
PM me your test code. I'd like to try it out on my own machine.

I am referencing it from BlockClicked within a Block. I was thinking at first that the x,y, and z were wrong and that it might be searching for the tile entity in the wrong block, but BlockCLicked should return itself...

Found the problem. A tile entity must extend BlockContainer to be treated as a tile entity by the chunk manager. In your case I made BlockPowered extend BlockContainer (which in turn extends Block) and made BlockPowered abstract, since I didn't know what you wanted to do with it. Will that work?

You're also missing a null check in calculateCurrentChanges(). It seems like you should be able to bail out after the first exception, but I couldn't figure out what the code was doing, so maybe not?

Ohh i see... Thanks a bunch. I do remember seeing something about extending BlockContainer now that I think about it...
