这啥Mod，貌似是他造成的。如果没有崩溃就别管了，崩溃就把他删除。

这是我正在写的mod，试运行时出了问题

Can't use a null-name for the registry

你看

public class BlockRegister {
    public static final Block BlockLingshikuang =new BlockLingshikuang();
    public BlockRegister(){
        MinecraftForge.EVENT_BUS.register(this);
    }
    @SubscribeEvent
    public static void registerBlock(RegistryEvent.Register<Block> event)
    {
        event.getRegistry().registerAll(
                BlockLingshikuang
        );
    }


这部分代码有什么问题吗？

at com.xiuzhen.xiuzhenmod.register.BlockRegister.registerBlock(BlockRegister.java:19) ~[BlockRegister.class:?]
看一下com.xiuzhen.xiuzhenmod.register.BlockRegister这个类的第19行有没有什么错误
