Been beating my head against the wall for a while on this one.

 

I am creating a block that should change it's model based on whether or not it is next to another one.

 

However I'm having this error and I can't seem to figure out what's going on.

 

Here is a single instance of the error

There are four block models

shelf_center_oak.json

shelf_left_oak.json

shelf_right_oak.json

shelf_single_oak.json

 

My BlockShelf.json (BlockState)

and finally my BlockShelf.java class

Any insight would be greatly appreciated. Though I am not yet familiar with the inner workings of MinecraftForge, nor would I call myself a Java expert, I am a Software Engineer and perfectly ok with Googling something i don't understand in your answer

That's not how Forge's blockstates format works. The format is documented here.

 

The

defaults

section can only contain the same values as a single variant would, it can't have multiple variants in it.

 

Each key in the

variants

section can either be a fully-defined variant (e.g.

connections=4,facing=east

or

normal

) or a property name (e.g.

connections

).

 

The value of a fully-defined variant key can either be an array of variants (in which case one will be chosen at random when the model is rendered) or a single variant (must not have an object as the first value, otherwise the deserialiser won't recognise it as a fully-defined variant).

 

The value of a property name key must be an object that maps each value of the property to a variant.

 

You can see some examples of the format here, here and here.

Awesome, thank you for the examples. I took a step away for a bit and while talking with my niece it suddenly occurred to me that I was thinking of the BlockState json in totally the wrong way.

 

This is what I have now. and though I'm changing the model in the wrong directions it is working, and that's a simple fix.

 

[EDIT] had my left and right backwards
