Tile Entities for Metadata > 15?

You coild do something like this:

 

TileEntityParent extends TileEntity{

// some methods and variables you want for all your TE's ie:

}

 

And then have your TE's extend TileEntityParent instead of Te.

Like EE3 has done. But thats not the question or reason for talking about parentTE's.

 

Hmm I guess you could have a TE which returns different TE's when called upon depending the value of a variable?

That is an interesting, if rather difficult to execute, idea.
