Trouble with initializing a new item for registry

Recommended Posts

Hi all, I'm new to the modding scene, and I've been reading the Forge Java doc recently to familiarize myself with the language of Forge API. However, I just encountered this very simple issue...I tried to register an item, and to set the group, I used "new Item.Properties().group(ItemGroup.TAB_MATERIALS)", but Java is saying that "Cannot resolve method 'group' in 'Properties'", which is very strange. This is my full code for the class. Thanks!

package com.example.examplemod;
import net.minecraft.item.Item;
import net.minecraft.item.ItemGroup;
import net.minecraftforge.fml.RegistryObject;
import net.minecraftforge.fml.javafmlmod.FMLJavaModLoadingContext;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;

public class RegistryHandler {

    public static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, ExampleMod.MODID);

    public static void init(){
        ITEMS.register(FMLJavaModLoadingContext.get().getModEventBus());
    }

    public static final RegistryObject<Item> TEST = ITEMS.register("test",
            ()-> new Item(
                    new Item.Properties().group(ItemGroup.TAB_MATERIALS)
                )
            );
}

Thank you! I just checked an youtube tutorial and found the same thing... turns out I'm looking at a slightly outdated java doc for 1.16.5 36.0.15.

I wonder if there's an updated java doc for the latest stable version of Forge, like this one: https://nekoyue.github.io/ForgeJavaDocs-NG/javadoc/1.16.5/overview-summary.html. Thanks again for your quick reply!

I do see javadoc when typing code and all possibilities come up for me to autocomplete my lines. But I was wondering if it's able to generate a document for all class and properties, etc. in the latest Forge version locally, with a format like in the link I gave above. I'm not too familiar with how to do that with gradle. Is there any one-liner to do this?

Apologize for the dumb question. But I only see 3 jars in my working environment right now: 1. forge mdk, 2. forge installer, 3. compiled mod jar. I tried these three with javadoc but none quite works. I also tried to search this online, but some older posts I see (like this:

) aren't quite helpful... because I'm still not sure which jar should I use and the ones I used doesn't seem to work.

There are a lot of external libraries which I assume are not the forge jar. Then I found this "forge-1.16.5-36.1.2_mapped_official_1.16.5-sources.jar_a3996c759375e74d54b8b3c98f4b2a5e" in build>tmp>expandedArchives. But it's not in jar format. How should I solve this, or am I looking at the wrong file? Is there any other way to inspect all libraries attached to an IntelliJ project. Thanks!

In IntelliJ you can right click a library and do "open library settings", which will show you the path to the sources jar.

Not sure exactly which library you are talking about so I'm most likely doing the wrong thing...sorry

Thank you! Obviously the list is so long and I didn't look at it careful enough before...

I unzipped and then renamed the folder before attemping: javadoc -d ForgeDocs -classpath ForgeSource -subpackages net

But it throw 100 errors due to some unrecognized symbols from other packages. Well, the problem is that I don't quite see any html output. How should I do this correctly?

Thanks Ben! I figured this out and put the results and the steps here: https://github.com/ziyuanzhao2000/Forge-API-Documentation/blob/main/README.md. Might be helpful to other new modders.

 

hmmm.... I still see a lot of obfuscated variable names. Are these normal given I was compiling the latest Forge mod?
