Noobish question about json files [1.8]

[ViceVersa]

so in the blockstates json files, a lot of them have number values such as

{"model": "tnt", "y": 90}

what exactly is "y": 90 referring to?

[Choonster]

The

"x"

and

"y"

values are the rotation around the x and y axes, respectively. This wiki page explains the vanilla blockstates and block/item model formats.

 

For blocks with many combinations of properties, you may want to use Forge's blockstates format which is explained here. This allows you to specify what effect each value has on the model and combine multiple models.
