[1.15.2] How should I use a blockstate or variants ?

[LicaSkelecario]

I can't use a blockstate well
the only thing that I can do a bit is to make variants which generate random blocks and when we destroy it they remain the same and rotate them a bit too

but the thing where I have the most difficulty understanding and where I have a lot of error is (true false) or more

for example, I tested something with snow and I often have errors like this

the result obviously gives me the block without texture

3:20.41 [Server-Worker-6/WARN] [minecraft/ModelBakery]: Unable to load model: 'testnt:block/bloc_1' referenced from: testnt:bloc_2#: java.io.FileNotFoundException: testnt:models/block/bloc_1.json 
33:20.41 [Server-Worker-6/WARN] [minecraft/ModelBakery]: Exception loading blockstate definition: 'testnt:blockstates/bfinale.json' in resourcepack: 'Mod Resources' for variant: 'snowy=false': Unknown blockstate property: 'snowy' 
33:20.41 [Server-Worker-6/WARN] [minecraft/ModelBakery]: Exception loading blockstate definition: 'testnt:blockstates/bfinale.json' in resourcepack: 'Mod Resources' for variant: 'snowy=true': Unknown blockstate property: 'snowy' 
33:20.41 [Server-Worker-6/WARN] [minecraft/ModelBakery]: Exception loading blockstate definition: 'testnt:blockstates/bfinale.json' missing model for variant: 'testnt:bfinale#'

{
  "variants": {
    "snowy=false": {"model": "testnt:block/b_middle"},
    "snowy=true": {"model": "testnt:block/b_top"}
  }
}

I tested with many others as the direction still true and false

 

I would like to know if he has someone who knows about it who could know how to use better

 

in detail I use Mcreator to code this

I know but it's also to learn a little more modding
