[1.12] Crash when Registering ItemBlock (I promise I set the registry name)

JoshJ5Hawk · July 10, 2019

Hello everyone,

I am having an interesting crash that I can't seem to track down, that seems to relate to either my ItemBlock registration, or my creative tab. I however lean towards my ItemBlock registration, as I do not get the crash when I comment out the ItemBlock registration, and I still get the crash with my Creative tab commented out. Any help would be greatly appreciated.

Thank you in advance for your time!

Welp. Josh is an idiot everyone. Make sure you use the same capitalization methods throughout your mod -.-

I suppose I'll ask this while its here instead of making a new post, semi related I guess. Does anything that I've shown jump out and say "This is why your textures aren't loading"?

~~Please post your log.~~ No longer needed.

1. Using your proxy as the event subscriber is a bad practice, as the one and only purpose is to run code on one dedicated side. Consider using another class for item/block registration instead of the proxies.

2. (Main issue) You have to subscribe to the ModelRegistryEvent and register your items there. An example would be

ModelLoader.setCustomModelResourceLocation(yourItem, metadata, new ModelResourceLocation(yourItem.getRegistryName(), "inventory"));

ModelLoader.setCustomModelResourceLocation(yourItem, metadata, new ModelResourceLocation(yourItem.getRegistryName(), "inventory"));

So I did actually add that a bit later, hopefully I called it correctly. I subscribed to it in my PoweredAnvil.java, the main class for the block itself, as such:

package joshj5hawk.firstmod.poweredAnvil;

import joshj5hawk.firstmod.FirstMod;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.block.model.ModelResourceLocation;
import net.minecraft.item.Item;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.client.model.ModelLoader;
import net.minecraftforge.fml.relauncher.SideOnly;
import net.minecraftforge.fml.relauncher.Side;

public class PoweredAnvil extends Block
{
    public static final ResourceLocation POWEREDANVIL = new ResourceLocation(FirstMod.MODID, "poweredanvil");

    public PoweredAnvil()
    {
        super(Material.IRON);
        setRegistryName(new ResourceLocation(FirstMod.MODID, "poweredanvil"));
        setUnlocalizedName(FirstMod.MODID + ".poweredanvil");
        setHarvestLevel("pickaxe", 1);
        setCreativeTab(FirstMod.tabFirstMod);
    }
    @SideOnly(Side.CLIENT)
    public void initModel()
    {
        ModelLoader.setCustomModelResourceLocation(Item.getItemFromBlock(this), 0, new ModelResourceLocation(getRegistryName(), "inventory"));
    }
}

And I have then called it in my ModBlocks.java

package joshj5hawk.firstmod;

import joshj5hawk.firstmod.poweredAnvil.PoweredAnvil;
import net.minecraftforge.fml.common.registry.GameRegistry;

public class ModBlocks
{
    @GameRegistry.ObjectHolder("firstmod:poweredanvil")
    public static PoweredAnvil poweredanvil;

    public static void initModels()
    {
        @SubscribeEvent
        poweredanvil.initModel();
    }
}

But I'm wondering if I just have a silly typo somewhere again. My block is showing up, albeit untextured and rather large in the player's hand lol, as well as the item as well. Is this the wrong place.

Additionally I've committed these changes to my git ( https://github.com/Joshj5hawk/FirstMod ) as well, if you can see anything else that jumps out at you.

Once I get this texture bit figured out, I'll look into getting those subscriber events elsewhere. Any suggestions there? Been following along with McJty's 1.12 tuts, but I'm always willing to learn better practices

Again, I appreciate the help. The last time I wrote a mod it was for ModLoader lol

DavidM · July 10, 2019

Your model registering code is not in your event subscriber for the ModelRegistryEvent, thus your code is not being called at all.

You need an event subscriber for the ModelRegistryEvent in your event subscriber bus (the CommonProxy in your case).

A typical event subscriber looks like this:

@SubscribeEvent
public static void someEventSubscriber(EventClass event) {
	// ...
}
