Forge Blockstate With Sub Variant?


DragonFerocity

Recommended Posts

Is it possible to define a variant for a block inside of another variant using the Forge Blockstate JSON?

 

As an example, I'm adding custom stairs to Minecraft, but in order to allow inner stairs and outer stairs the y needs to change based on which direction the stair block is facing AND which type of stairs it is (inner, outer, or straight).

 

Is it possible to define this using the Forge Blockstate JSON?

 

(Here's the JSON i'm currently using which doesn't rotate the block correctly for inner stairs:

Forge's blockstates format only allows you to specify the effects of individual property values or fully-defined variants, you can't specify the effects of a subset of properties (e.g. two of three properties).

 

You also can't specify the x and y rotation separately, if you specify one then the other will be 0 for that variant.

 

You could use an IStateMapper to have a different blockstates file for each value of one of the properties or use Vanilla's multipart blockstates format; but I think you may be best off with a single Forge blockstates file with fully-defined variants.
