public class ModTags {
    public static class Blocks {

        public static final TagKey<Block> METAL_DETECTOR_DETECTABLE_BLOCKS = createTag("metal_detector_detectable_blocks");

        public static TagKey<Block> createTag(String name) {
            return TagKey.of(RegistryKeys.BLOCK, Identifier.of(DemoMod1.MOD_ID, name));
        }
    }

    public static class Items {
        public static TagKey<Item> createTag(String name) {
            return TagKey.of(RegistryKeys.ITEM, Identifier.of(DemoMod1.MOD_ID, name));
        }
    }

}

修改我们之前金属探测器的代码：

private boolean isValuableBlock(BlockState state) {
    // return state.isOf(Blocks.IRON_ORE) || state.isOf(Blocks.DIAMOND_ORE);
    return state.isIn(ModTags.Blocks.METAL_DETECTOR_DETECTABLE_BLOCKS);
}

这样就可以使用多个标签了

最后还需要在resource/data/tutorialmod/tags/blocks/metal_detector_detectable_blocks.json中添加：

{
  "replace": false,
  "values": [
    "tutorialmod:ruby_ore",
    "#minecraft:gold_ores",
    "#minecraft:emerald_ores",
    "#minecraft:redstone_ores",
    "#minecraft:lapis_ores",
    "#minecraft:diamond_ores",
    "#minecraft:iron_ores",
    "#minecraft:copper_ores",
    "#minecraft:coal_ores"
  ]
}
