注册了，注册方块在另一个类中完成，这是代码： public static Block block = new BlockEntityTest2()
.setRegistryName("world_editor:block_entity_test2")
.setTranslationKey("world_editor.block_entity_test2")
.setCreativeTab(CommonProxy.WorldEditorCreativeTabs);
@SubscribeEvent
public static void registerBlock(RegistryEvent.Register<Block> event) {
event.getRegistry().register(block);
GameRegistry.registerTileEntity(BlockEntityTest2.MyLavaFurnaceEntity.class, new ResourceLocation("world_editor:block_entity_test2"));
}
@SubscribeEvent
public static void registerItem(RegistryEvent.Register<Item> event) {
Item itemBlock = new ItemBlock(block).setRegistryName(block.getRegistryName());
ModelLoader.setCustomModelResourceLocation(itemBlock, 0,
new ModelResourceLocation(itemBlock.getRegistryName(), "inventory")
);
event.getRegistry().register(itemBlock);

请保证 TileEntity 类型含有一个零参数构造器。 |

如果你有声明其他非零参构造器，那么你需要显式地声明一个零参数构造器，即： public MyLavaFurnaceEntity() {
}另外，我在你提供的代码中并没有看到其他的构造器，怀疑是提供的代码不完整。如果问题仍然没有解决，请提供完整的代码。 |

我的确没有给TileEntity声明构造函数，而是和教程中一样使用了隐式声明的默认构造器，我现在加上构造函数但问题仍然没有解决，请问日志中能看出其他可能导致这个结果的错误么，我现在加上了构造函数并将注册方块的部分放到了BlockEntityTest2中方便您帮助我找出问题，这是完整代码 package com.bfwqzj.world_editor.block.block_entity;

非常感谢，原来问题在于static，我主要使用的语言是c++所以对java的内部类需要static修饰符并不不了解，非常感谢你愿意花时间帮助我，我的mod开发进度因为这个问题停留了3天了而且Forge论坛不接受1.12的问题让我感觉很无助 |

我按照教程对
readFromNBT和writeToNBT进行了覆写，但重新载入地图后nbt还是会被清空。我开始尝试各种方法找原因，我先是尝试了数据同步，结果还是不行。之后我通过调试发现
writeToNBT虽然能正常调用但每次tag都是空的，我开始怀疑问题的原因是writeToNBT没有保存，但我没办法确认他是不是真的没有保存 因为我不知道成功的情况下tag是否也是空的，这是我的代码：Beta Was this translation helpful? Give feedback.
