I'm working in my RegistryEvents.java, trying to register an item called sap_bucket using this declaration in the event.getRegistry().registerAll() line of registerItems with this declaration:

 

ItemList.sap_bucket = new BucketItem(() -> FluidList.sap, new Item.Properties().group(ItemGroup.MISC).maxStackSize(1)).setRegistryName("sap_bucket")

However, Eclipse is saying that the constructor BucketItem(() -> {}, Item.Properties) is undefined.

 

Similarly, I'm trying to register the sap block called sapt using this declaration in the event.getRegistry().registerAll() line of registerBlocks with this declaration:

BlockList.sap = new FlowingFluidBlock(() -> FluidList.sap, new Block.Properties.create(Material.WATER).doesNotBlockMovement().noDrops()).setRegistryName(location("sap"))

but Eclipse says that it can't resolve Block.Properties.create to a type. For some reason. It's a method, but Eclipse isn't recognizing it as such. Weird.

Does anyone know how to fix this? (And is it a problem that I'm using Java 8?)

new Block.Properties.create(

Remove the new keyword.

I did that, but now it's saying that the constructor FlowingFluidBlock(() -> {}, Block.Properties) is undefined. On top of that, when I mouse over either of the () -> FluidList.sap expressions, it says, "The target type of this expression must be a functional interface." What does that mean?

Post your updated code.

ItemList.sap_bucket = new BucketItem(() -> FluidList.sap, new Item.Properties().group(ItemGroup.MISC).maxStackSize(1)).setRegistryName("sap_bucket")

and the block:

BlockList.sap = new FlowingFluidBlock(() -> FluidList.sap, Block.Properties.create(Material.WATER).doesNotBlockMovement().noDrops()).setRegistryName(location("sap"))

Also, should I be using Java 12 or 8?

You should be using Java 8. Also the code looks fine.

Alright, found the problem. I didn't realize I had to import java.util.function.Supplier.

...it's still saying that the constructors for BucketItem(lambda expression here, Item.Properties) and FlowingFluidBlock(() -> {}, Block.Properties) are undefined. It looks like both the constructors take suppliers.

Wait, no, now it's working. I don't know why. Maybe it's because I imported the relevant classes? Oh well, at least I learned about lambdas. Thank you!
