如何在 Forge 中将 setBlock() 与自定义方块一起使用？

Question

所以，我正在制作一个模组，我想使用 level.setBlock()，我是这样使用的：

level.setBlock(pos, Blocks.DIRT.defaultBlockState(), 1);

并且它有效但是当我想设置我的自定义块时，我有这个错误：

The method setBlock(BlockPos, BlockState, int) in the type Level is not applicable for the arguments (BlockPos, RegistryObject<Block>, int).

问题是我不能将 defaultBlockState() 与我的自定义块一起使用，但我想这样做

level.setBlock(pos, ModBlocks.lock, 1)

.

所以我发现我能做到：

level.setBlock(pos, ModBlocks.lock.get().defaultBlockState(), 1);
