I want my TE not to render some parts if there is another equal TE on its left, right or top. this is what I've come up with for now, I'm testing if it works right now. I was wondering what offset stands for ( english is not my first language) and if it can help me...

@Override
	public void updateEntity() {


		if(hasLeft()) System.out.println("d");




	}


	public boolean hasLeft() {

		TileEntity te;
		switch(this.facing) {
		case NORTH: te = this.getWorldObj().getTileEntity(this.xCoord+1, this.yCoord, this.zCoord); break;
		case SOUTH: te = this.getWorldObj().getTileEntity(this.xCoord-1, this.yCoord, this.zCoord); break;
		case EAST:  te = this.getWorldObj().getTileEntity(this.xCoord, this.yCoord, this.zCoord-1); break;
		case WEST:  te = this.getWorldObj().getTileEntity(this.xCoord, this.yCoord, this.zCoord+1); break;
		default: te = null; break;
		}



		if(te instanceof TileEntityShelve) {
			return true;
		} else
			return false;

	}
