I've searched through videos and websites, as well as the forge docs, but I can't find how to properly add a custom blockstate to my custom-modeled block. I'm trying to change the texture of the block whenever I right click it, but nothing I add in seems to work correctly. I keep getting the correct hitbox, but no model or texture is recognized. What is the proper way to do this for the newest version?

Luckily there's a vanilla block that has this functionality already: the daylight detector. The blockstate for that looks like:

{
  "variants": {
    "inverted=false": {
      "model": "minecraft:block/daylight_detector"
    },
    "inverted=true": {
      "model": "minecraft:block/daylight_detector_inverted"
    }
  }
}

So you can adapt your blockstate to use true/false flags like that. Now we need to look at the class file for the daylight detector to see how the tags are implemented. I've added the relevant parts here.

public static final BooleanProperty INVERTED = BlockStateProperties.INVERTED;

public DaylightDetectorBlock(AbstractBlock.Properties properties) {
        super(properties);
        this.setDefaultState(this.stateContainer.getBaseState().with(INVERTED, Boolean.FALSE));
    }

public ActionResultType onBlockActivated(BlockState state, World worldIn, BlockPos pos, PlayerEntity player, Hand handIn, BlockRayTraceResult hit) {
        if (player.isAllowEdit()) {
            if (worldIn.isRemote) {
                return ActionResultType.SUCCESS;
            } else {
                BlockState blockstate = state.func_235896_a_(INVERTED);
                worldIn.setBlockState(pos, blockstate, 4);
                return ActionResultType.CONSUME;
            }
        } else {
            return super.onBlockActivated(state, worldIn, pos, player, handIn, hit);
        }
    }

Remember to add to state to the state container.

Thanks for the help! I just realized my mistake: for some reason, in the block.json file, if I insert a space between two attributes, it doesn't recognize the second one. I fixed it, and now my block works perfectly

Adding onto it, is there any way I can change it so you can only toggle it once?

Do you mean so that when its toggled, it just stays always in that state? just use the value of your boolean property then...the first time the block gets toggled your boolean property will become true (or false, depends on the default value you set before)..you have to make it so that the next time it won't toggle if the boolean property has already changed

The if statement won't let me compare a BooleanProperty to a Boolean because apparently they're two separate things, and I have no idea how to fix this.

A BooleanProperty is an object that says "a blockstate is allowed to have two values: true and false."

It is not, itself, the state of the block in the world. Getting a bool from the blockstate is simple: you ask the blockstate for its value.

How would I get a value from the blockstate itself?

BlockState.get(property)

.get doesn't seem to work for me. 

Nevermind, I had a different name specified in my arguments, so for me it was just state.get(). All works find now, thanks for the help.
