20自定义作物

代码

自定义番茄庄稼：

public class TomatoCropBlock extends CropBlock {
    public static final int MAX_AGE = 5;
    public static final IntProperty AGE = Properties.AGE_5;

    public TomatoCropBlock(Settings settings) {
        super(settings);
    }

    @Override
    protected ItemConvertible getSeedsItem() {
        return ModItems.TOMATO_SEEDS;
    }

    @Override
    public IntProperty getAgeProperty() {
        return AGE;
    }

    @Override
    public int getMaxAge() {
        return MAX_AGE;
    }

    @Override
    protected void appendProperties(StateManager.Builder<Block, BlockState> builder) {
        builder.add(AGE);
    }
}

在ModItems中注册物品

public static final Item TOMATO_SEEDS = registerItem("tomato_seeds",
        new AliasedBlockItem(ModBlocks.TOMATO_CROP, new FabricItemSettings()));

在ModBlocks中注册块

public static final Block TOMATO_CROP = Registry.register(Registries.BLOCK, new Identifier(TutorialMod.MOD_ID, "tomato_crop"),
        new TomatoCropBlock(FabricBlockSettings.copyOf(Blocks.WHEAT)));

掉落物生成器中添加ModLootTableProvider：

BlockStatePropertyLootCondition.Builder builder = BlockStatePropertyLootCondition.builder(ModBlocks.TOMATO_CROP).properties(StatePredicate.Builder.create()
        .exactMatch(TomatoCropBlock.AGE, 5));
addDrop(ModBlocks.TOMATO_CROP, cropDrops(ModBlocks.TOMATO_CROP, ModItems.TOMATO, ModItems.TOMATO_SEEDS, builder));

ModModelProvider中添加：

blockStateModelGenerator.registerCrop(ModBlocks.TOMATO_CROP, TomatoCropBlock.AGE, 0, 1, 2, 3, 4, 5);

在TutorialModClient中添加：

public class TutorialModClient implements ClientModInitializer {
    @Override
    public void onInitializeClient() {
        BlockRenderLayerMap.INSTANCE.putBlock(ModBlocks.RUBY_DOOR, RenderLayer.getCutout());
        BlockRenderLayerMap.INSTANCE.putBlock(ModBlocks.RUBY_TRAPDOOR, RenderLayer.getCutout());

        BlockRenderLayerMap.INSTANCE.putBlock(ModBlocks.TOMATO_CROP, RenderLayer.getCutout());
    }
}

除此之外，还需要注意添加番茄各阶段的图片，以及番茄的翻译
