非典型方塊

我們昨天講到，非典型方塊的註冊，我們繼續講一些註冊上的參數。

 public static final Block SIDERITE_FENCE_GATE = registerBlock("siderite_fence_gate",
            new FenceGateBlock(FabricBlockSettings.copyOf(Blocks.IRON_BLOCK), WoodType.ACACIA));

這裡我們註冊了柵欄門，我們在最後一個參數指定了木頭的材質，雖然這個柵欄們還是我們的隕鐵外觀，不過樣式上會跟指定的木頭材質一樣。

    public static final Block SIDERITE_TRAPDOOR = registerBlock("siderite_trapdoor",
            new TrapdoorBlock(FabricBlockSettings.copyOf(Blocks.IRON_BLOCK).nonOpaque(), BlockSetType.STONE));

這是我們註冊活板門的程式，可以看到這裡有nonOpaque，代表這個活版們可以讓光線通過，不是完全不透明。

回到我們的DataGen，我們可以發現其實這些物品的合成表都與原版是相同的規律，程式上我們也只需要這樣寫

offerSlabRecipe(exporter, RecipeCategory.BUILDING_BLOCKS,ModBlocks.SIDERITE_SLAB,Moditems.Siderite);

        offerWallRecipe(exporter, RecipeCategory.BUILDING_BLOCKS,ModBlocks.SIDERITE_WALL,Moditems.Siderite );

        offerPressurePlateRecipe(exporter, ModBlocks.SIDERITE_PRESSURE_PLATE, Moditems.Siderite);

        createDoorRecipe(ModBlocks.SIDERITE_DOOR, Ingredient.ofItems(Moditems.Siderite)).criterion(hasItem(Moditems.Siderite),conditionsFromItem(Moditems.Siderite)).offerTo(exporter, new Identifier(getRecipeName(ModBlocks.SIDERITE_DOOR)));

        createFenceRecipe(ModBlocks.SIDERITE_FENCE, Ingredient.ofItems(Moditems.Siderite)).criterion(hasItem(Moditems.Siderite),conditionsFromItem(Moditems.Siderite)).offerTo(exporter, new Identifier(getRecipeName(ModBlocks.SIDERITE_FENCE)));

        createFenceGateRecipe(ModBlocks.SIDERITE_FENCE_GATE, Ingredient.ofItems(Moditems.Siderite)).criterion(hasItem(Moditems.Siderite),conditionsFromItem(Moditems.Siderite)).offerTo(exporter, new Identifier(getRecipeName(ModBlocks.SIDERITE_FENCE_GATE)));

        createStairsRecipe(ModBlocks.SIDERITE_STAIRS, Ingredient.ofItems(Moditems.Siderite)).criterion(hasItem(Moditems.Siderite),conditionsFromItem(Moditems.Siderite)).offerTo(exporter, new Identifier(getRecipeName(ModBlocks.SIDERITE_STAIRS)));

        createTrapdoorRecipe(ModBlocks.SIDERITE_STAIRS, Ingredient.ofItems(Moditems.Siderite)).criterion(hasItem(Moditems.Siderite),conditionsFromItem(Moditems.Siderite)).offerTo(exporter, new Identifier(getRecipeName(ModBlocks.SIDERITE_TRAPDOOR)));

可以看到我們前三個物品都是使用offerXXXRecipe 我們基本上帶入exporter 產物跟原料即可，後面的四個我們就沒有offerXX這種方法了，我們必須使用createXXXRecipe，參數中我們先指定我們的產物，下一個參數是我們的原料，我們使用Ingredient.ofItems指定原料，criterion讓玩家只有在已經獲得原料(這裡是siderite)的狀況下解鎖合成表，offerTo()再將合成表交給datagen。
