So, for some reason, IntelliJ isn't able to resolve the constructer. I really need some help with the properties.

public static final RegistryObject<Block> GRIMSTONESTAIRS= BLOCKS.register("grimstone_bricks_stairs",() -> new StairBlock(BlockBehaviour.Properties.of(Material.HEAVY_METAL).strength(1.5f,0.5f).sound(SoundType.DEEPSLATE)));

 

did you looked at the constructor, since the constructor need the default Block as an Supplier like the OakStair has the OakBlock as default

Well, if you mean this, it doesn't work either.

public static final RegistryObject<Block> GRIMSTONESTAIRS= BLOCKS.register("grimstone_bricks_stairs",() -> new StairBlock(GRIMSTONEBRICK.get(), BlockBehaviour.Properties.of(Material.HEAVY_METAL).strength(1.5f,0.5f).sound(SoundType.DEEPSLATE)));

 

it needs the default BlockState as an Supplier, and not only the default Block

You have to add .defaultBlockState and COPY the block. Here an example:

public static final RegistryObject<Block> CUSTOM_STAIRS = BLOCKS.register("custom_stairs", () ->
            new StairBlock(CUSTOM_PLANKS.get().defaultBlockState(), BlockBehaviour.Properties.copy(MANGROVE_PLANKS.get()).strength(0.3F, 0.3F))
    );
