[1.7.2]Connect customly rendered blocks?

[EctoWarrior]

Hello everyone. I have a customly rendered table, and I am trying to figure out how to connect two tables if they are placed next to each other, similar to a fence or iron bar. I haven't seen much on how to do this, but I think I have it half done. The table that I place down next to it will update it's model accordingly, but the other one that is already there won't.

 

Here are some screenshots of the situation:

As you can see, the other two adjacent tables are not updating their model, even though they should be.

 

So I guess I have two questions:

1. How can I change a currently existing block's model?

2. If I'm doing this the complete wrong way, what is the best way of doing it?

 

Here is some of the code that I currently have:

Thanks in advance for any help.

Hi

 

Personally, I would do this completely without TileEntities, just using Blocks and Metadata.  There are quite a few vanilla examples of this (fence, for example, like you said, or panes).  Whenever a block is placed or destroyed, it  makes a call to all its neighbors (I forget which method but it's easy to spot) so that they can update their metadata and change their displayed texture.

 

You can do the same thing with TileEntities too (just trigger the model change from the block update-my-neighbor method), but I suspect you don't need them.

PS your method UpdateModel should be updateModel, otherwise it looks like a constructor.
