[1.10.2][UNSOLVED and CLOSED] Forge blockstate varient system

SHsuperCM · August 2, 2016

on another post i saw this in a blockstate json:

  "forge_marker": 1,
  "defaults": {
    "transform": "forge:default-block"
  }

what is it and how can i use it to have 1 block with all sorts of varients that use diffrent json models and how can i place said varients within the code to a

World

Choonster · August 3, 2016

Forge's blockstates format is documented here.

SHsuperCM · August 3, 2016

I still do not understand.. the documation did not help sadly.....

How can i make it use diffrent json models

and set them in the world through code..

Is there an example of what im trying to do somewhere?

listen... i am.... what do you call it... dumb?.. ye, that's what i am....

i still do not understand how i can use it... its so confusing....

i think i need to also do something with this:

public static enum EnumType implements IStringSerializable
    {
        OAK(0, "oak", MapColor.WOOD),
        SPRUCE(1, "spruce", MapColor.OBSIDIAN),
        BIRCH(2, "birch", MapColor.SAND),
        JUNGLE(3, "jungle", MapColor.DIRT),
        ACACIA(4, "acacia", MapColor.ADOBE),
        DARK_OAK(5, "dark_oak", "big_oak", MapColor.BROWN);

        private static final BlockPlanks.EnumType[] META_LOOKUP = new BlockPlanks.EnumType[values().length];
        private final int meta;
        private final String name;
        private final String unlocalizedName;
        /** The color that represents this entry on a map. */
        private final MapColor mapColor;

        private EnumType(int metaIn, String nameIn, MapColor mapColorIn)
        {
            this(metaIn, nameIn, nameIn, mapColorIn);
        }

        private EnumType(int metaIn, String nameIn, String unlocalizedNameIn, MapColor mapColorIn)
        {
            this.meta = metaIn;
            this.name = nameIn;
            this.unlocalizedName = unlocalizedNameIn;
            this.mapColor = mapColorIn;
        }

        public int getMetadata()
        {
            return this.meta;
        }

        /**
         * The color which represents this entry on a map.
         */
        public MapColor getMapColor()
        {
            return this.mapColor;
        }

        public String toString()
        {
            return this.name;
        }

        public static BlockPlanks.EnumType byMetadata(int meta)
        {
            if (meta < 0 || meta >= META_LOOKUP.length)
            {
                meta = 0;
            }

            return META_LOOKUP[meta];
        }

        public String getName()
        {
            return this.name;
        }

        public String getUnlocalizedName()
        {
            return this.unlocalizedName;
        }

        static
        {
            for (BlockPlanks.EnumType blockplanks$enumtype : values())
            {
                META_LOOKUP[blockplanks$enumtype.getMetadata()] = blockplanks$enumtype;
            }
        }
    }

im really really confused on how i can take this to my advantage...

Basically you use the new BlockState system

// Code from BlockPlanks
    @SideOnly(Side.CLIENT)
    // Adds all blockstates to creative tab(s)
    public void getSubBlocks(Item itemIn, CreativeTabs tab, List<ItemStack> list)
    {
        for (BlockPlanks.EnumType blockplanks$enumtype : BlockPlanks.EnumType.values())
        {
            list.add(new ItemStack(itemIn, 1, blockplanks$enumtype.getMetadata()));
        }
    }

    /**
     * Convert the given metadata into a BlockState for this Block
     */
    public IBlockState getStateFromMeta(int meta)
    {
        return this.getDefaultState().withProperty(VARIANT, BlockPlanks.EnumType.byMetadata(meta));
    }

    /**
     * Get the MapColor for this Block and the given BlockState
     */
    // Just changes the color that will be displayed on minmaps for example
    public MapColor getMapColor(IBlockState state)
    {
        return ((BlockPlanks.EnumType)state.getValue(VARIANT)).getMapColor();
    }

    /**
     * Convert the BlockState into the correct metadata value
     */
    public int getMetaFromState(IBlockState state)
    {
        return ((BlockPlanks.EnumType)state.getValue(VARIANT)).getMetadata();
    }
    
    // Does exactly what it says
    protected BlockStateContainer createBlockState()
    {
        return new BlockStateContainer(this, new IProperty[] {VARIANT});
    }

This allows you to add different models to the base model on different blockstates. I assume, but don't quote me, but you may also be able to change the base model. I(t will also allow you to change the texture(s). And a plus side is you do it in just one file, so you still only need 3 JSONs for one block (Yeah still kinda upset about that...).

so this is whats happening:

brain: cmon you fudging idiot you did way more complex things than a stupid blockstate for multiple blocks!

me: shut up you know im stupid because of you!

brain: why cant you understand the simplest of things!?

me: for me its not simple!

and it goes for ever and ever...

i'd really really like to know the forge blockstates and i think it will help me a butt ton... but i find it too hard for me to understand... i think ill just register each of the blocks i need for this structure seperately.....

annd it is a symetric shape so i'd have to register 4 blocks for each one but i can do some work on it....

Animefan8888 · August 3, 2016

Here let me go into a little bit more of a in depth example once again using the BlockPlanks code, anyone that sees something wrong in this please correct me because I have not messed around with it I am only going on intuition and what I have seen.

The Enum in BlockPlanks

    public static enum EnumType implements IStringSerializable
    {
        OAK(0, "oak", MapColor.WOOD),
        SPRUCE(1, "spruce", MapColor.OBSIDIAN),
        BIRCH(2, "birch", MapColor.SAND),
        JUNGLE(3, "jungle", MapColor.DIRT),
        ACACIA(4, "acacia", MapColor.ADOBE),
        DARK_OAK(5, "dark_oak", "big_oak", MapColor.BROWN);

        private static final BlockPlanks.EnumType[] META_LOOKUP = new BlockPlanks.EnumType[values().length];
        private final int meta;
        private final String name;
        private final String unlocalizedName;
        /** The color that represents this entry on a map. */
        private final MapColor mapColor;

        private EnumType(int metaIn, String nameIn, MapColor mapColorIn)
        {
            this(metaIn, nameIn, nameIn, mapColorIn);
        }

        private EnumType(int metaIn, String nameIn, String unlocalizedNameIn, MapColor mapColorIn)
        {
            this.meta = metaIn;
            this.name = nameIn;
            this.unlocalizedName = unlocalizedNameIn;
            this.mapColor = mapColorIn;
        }

        public int getMetadata()
        {
            return this.meta;
        }

        /**
         * The color which represents this entry on a map.
         */
        public MapColor getMapColor()
        {
            return this.mapColor;
        }

        public String toString()
        {
            return this.name;
        }

        public static BlockPlanks.EnumType byMetadata(int meta)
        {
            if (meta < 0 || meta >= META_LOOKUP.length)
            {
                meta = 0;
            }

            return META_LOOKUP[meta];
        }

        public String getName()
        {
            return this.name;
        }

        public String getUnlocalizedName()
        {
            return this.unlocalizedName;
        }

        static
        {
            for (BlockPlanks.EnumType blockplanks$enumtype : values())
            {
                META_LOOKUP[blockplanks$enumtype.getMetadata()] = blockplanks$enumtype;
            }
        }
    }

Just holds all of the data, like the metadata, an unlocalized name, and the Color for the map.

Now if I were to guess the JSON would go something like

{
    "forge_marker": 1,
    "defaults": {
        "textures": {
            "texture": "blocks/planks_oak",
            "wall": "blocks/planks_oak"
        },
        "model": "oak_planks",
        "uvlock": true
    },
    "variants": {
        // mossy is a boolean property.
        "oak": {
			"model": "oak_planks"
                "textures": {
                    "texture": "blocks/planks_oak"
                }
            },
	"birch": {
			"model": "birch_planks"
			"textures": {
				"texture": "blocks/planks_birch"
			}
		},
		"jungle": {
			"model": "jungle_planks"
			"textures": {
				"texture": "blocks/planks_jungle"
			}
		},
		"acacia": {
			"model": "acacia_planks"
			"textures": {
				"texture": "blocks/planks_acacia"
			}
		},
		"dark_oak": {
			"model": "dark_oak_planks"
			"textures": {
				"texture": "blocks/planks_dark_oak"
			}
		}
        }
    }
}

Though I may be wrong I didn't test this as said above.

Also the specific property used

// Uses an Enum you don't have to, but I makes the code look better in my opinion.
public static final PropertyEnum<BlockPlanks.EnumType> VARIANT = PropertyEnum.<BlockPlanks.EnumType>create("variant", BlockPlanks.EnumType.class);

Draco18s · August 3, 2016

Actually it would be:

},
    "variants": {
      "variant": {
        "oak": {
                "model": "oak_planks"
                "textures": {
                    "texture": "blocks/planks_oak"
                }
            },

The variant name (in this case "variant" because of the string passed to

PropertyEnum.<BlockPlanks.EnumType>create("variant", BlockPlanks.EnumType.class);

) creates a block, inside which you list all the variants associated with it. Notice how "mossy" had a top-level block that contained both "true" and "false."

Of course, you should give your variant a better than than "variant" such as "wood_type."

I've got a two-property example here:

https://github.com/Draco18s/ReasonableRealism/blob/master/src/main/resources/assets/harderores/blockstates/axel.json

Though my enums are set up differently.

    "variants": {
      "variant": {
        "oak": {
			"model": "oak_planks"

                    "texture": "blocks/planks_oak"

im not working now.. just got this in my email.. i plan to work on the mod later today... how can i place said variants within code? i have them in a structure that im doing for my mod and i only need them to be placed within code.. no play player placement...

Draco18s · August 3, 2016

You need to create the variant:

public static final PropertyEnum<BlockPlanks.EnumType> VARIANT = PropertyEnum.<BlockPlanks.EnumType>create("variant", BlockPlanks.EnumType.class);

Register it by overriding

protected BlockStateContainer createBlockState()

And finally translate between the states and meta by overriding

public IBlockState getStateFromMeta(int meta)

and

public int getMetaFromState(IBlockState state)

Do note that you're still limited to 16 possible values for metadata. Blockstates aren't magic.

Thanks i new i was missing something, glad it was something as simple as that as i was just stat8ng my hypothesis.

waaait really!? awww man that ruined so much of my plans! man this is really confusing stuff...

i think il just register blocks for each type and then, how can i use the orientable blocks? like a furnace for example... i want 1 block to have 4 possible directions and to be able to place them within code...

Just look at BlockFurnace try to wrap you mind around that, then have your models parent be block/orientable

SHsuperCM · August 4, 2016

Then how can I place these within code? I'v working on some stuff to make registering directional blocks ezier...

Animefan8888 · August 4, 2016

How can you place orientable blocks with in the code, look at BlockFurnace it has all of the code for that.

These blocks wont be containers.. Is there anything to do with

BlockDirectional

instead?

Animefan8888 · August 4, 2016

Anything to do with

public static final PropertyDirection FACING = BlockHorizontal.FACING;

in the BlockFurnace class is basically what you need.

You can have more than 16 possible states, they just can't be stored in metadata. It's either taken from the world or taken from the tile entity (using

getActualState()

)

SHsuperCM · August 5, 2016

no need anymore... i started to work on blocks within code to add them...
