I'm adding a series of blocks in my mod that will essentially allow one to wirelessly power RF blocks.

 

I have a couple problems with the code, however.

 

I have this code in one tile (the one powering the block):

public void updateTargets() // Updates provider and other blocks in series.
{
	targets.clear();
	for(int xOffset = -5; xOffset < 6; xOffset++)
	{
		for(int yOffset = -5; yOffset < 6; yOffset++)
		{
			for(int zOffset = -5; zOffset < 6; zOffset++)
			{
				TileEntity te = worldObj.getTileEntity(xCoord - xOffset, yCoord - yOffset, zCoord - zOffset);
				if(te != null && te instanceof IRFLaserTarget)
				{
					if(te != this) 
					{
						targets.add((IRFLaserTarget)te);
						((IRFLaserTarget)te).updateTargets();
					}
				}
				else if(te instanceof TileEntityRFLaser)
				{
					System.out.println("Found Provider");
					provider = (TileEntityRFLaser)te;
				}
			}
		}
	}
}

@Override
public void updateEntity() // Powers block
{
	for(int xOffset = -3; xOffset < 4; xOffset++)
	{
		for(int yOffset = 0; yOffset < -5; yOffset--)
		{
			for(int zOffset = -1; zOffset < 1; zOffset++)
			{
				TileEntity tile = worldObj.getTileEntity(xCoord - xOffset, yCoord - yOffset, zCoord - zOffset);
				if(tile instanceof IEnergyReceiver)
				{
					if(((IEnergyReceiver)tile).receiveEnergy(ForgeDirection.DOWN, 8000, true) != 0 && provider.storage.extractEnergy(((IEnergyReceiver)tile).receiveEnergy(ForgeDirection.DOWN, 8000, true), true) != 0)
					{
						provider.storage.extractEnergy(((IEnergyReceiver)tile).receiveEnergy(ForgeDirection.DOWN, 8000, false), false);
					}
				}
			}
		}
	}
}

 

The updateEntity() method never executes. I've tried System.out.println()s in several spots and there is nothing happening.

 

I do have my tiles registered and a block for each tile.

What is your forge version and how did you registered the block and tileentity?

10.13.2.1230 and by using GameRegistry.registerTileEntity() in my preInit method.

You also need to override Block#hasTileEntity(int metadata) and Block#createTileEntity(World world, int metadata).

In hasTileEntity you should return true(if it is not meta-block),

and in Block#createTileEntity you should return the instance of the tileentity.
