[1.10.2 -- b2076] Custom Air

[jeffryfisher]

My new mod is trying to replace some air with something like smoke. In every way, it is air (and the class extends BlockAir) except that it has a slight opacity to attenuate light levels passing through it.

 

Amazingly, my current code behaves (in game) the way I want. However, the console spews a bunch of warnings and errors during loading that scream about blockstate variants and models that I neither need nor want (and I'm already ignoring the the block's only property). Wanting a mod that is "clean" (so as not to alarm skittish users), I am wondering how best to avoid the error messages.

 

My first approach was to look for the blockstates and model files for BlockAir, but they don't exist. The treatment of vanilla air is deeply embedded in the coding of many disjoint classes within Minecraft.

 

Is there a recommended way to let Forge know that my block is "air", and therefore needs neither blockstate not model? If not, then what's the best way to trivialize the blockstates file (and avoid the need for a model file)?

 

Errors that I am trying to silence (and yes, I have already declared a custom state mapper to ignore shadowlevel):

I just want it to shutup and treat it like air.

[jeffryfisher]

OK, it looks like I need to extend StateMapperBase and override putStateModelLocations to simply return mapStateModelLocations  without ever putting anything into it.

 

I am hoping that will take care of "normal" (which is deeply rooted in a bunch of vanilla code that keeps adding it wherever property strings are empty).

 

That leaves "inventory". I suspect it's creeping in because my default shared code creates an ItemBlock for every block it registers. Since my block should never drop or appear in inventory, I'll look into my library code and avoid making an ItemBlock if that's what's happening.

Give yourself a separate registration method that doesn't do items.  It's what I did.

Also, statemapper stuff is client side.

You don't need to extend StateMapperBase only implement IStateMapper

[jeffryfisher]

You don't need to extend StateMapperBase only implement IStateMapper

 

I'll consider that during debugging, but my initial design will mimic vanilla's registrations with state mappers. If it turns out that I can't usefully inherit anything from StateMapperBase, then I'll dump it.
