Trying to get back into modding, and the new rendering system doesn't seem to complicated, except I can't get it to work. The item renders as a black and purple cube in my inventory.

 

 

Here's the console output: http://pastebin.com/BjWcKWkG

 

And here's the code:

 

 

Inside main mod class

    @Mod.EventHandler
    public void onPreInitialization(FMLPreInitializationEvent event) {
        FMLLog.info("Currently initializing %s version %s,", Reference.MOD_ID, Reference.VERSION);
        ConfigurationHandler.init(event.getSuggestedConfigurationFile());

        ModItems.init();
        proxy.onPreInitialization(event);
    }

    @Mod.EventHandler
    public void onInitialization(FMLInitializationEvent event) {

        proxy.onInitialization(event);
    }

    @Mod.EventHandler
    public void onPostInitializing(FMLPostInitializationEvent event) {
        proxy.onPostInitializationEvent(event);
        FMLLog.info("Finished initializing.");
    }

 

Inside the ClientProxy class

    @Override
    public void onPreInitialization(FMLPreInitializationEvent event) {
        // register key bindings
    }

    @Override
    public void onInitialization(FMLInitializationEvent event) {
        ResourceLocationHelper.registerItemRenderer(ModItems.denseMatterVessel);
    }

 

Inside ResourceLocationHelper

    public static void registerItemRenderer(ItemQSBase item) {
        Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(
                item,
                0,
                new ModelResourceLocation(
                        Reference.UNIVERSAL_PREFIX + Reference.MOD_ID_LOWERCASE + item.getUnwrappedUnlocalizedName(),
                        "inventory"
                )
        );
    }

 

Inside the ModItems class

    public static ItemDenseMatterVessel denseMatterVessel;

    public static void init() {
        GameRegistry.registerItem(denseMatterVessel = new ItemDenseMatterVessel(), "denseMatterVessel");

        denseMatterVessel.setCreativeTab(CreativeTabQuantumStorage.INSTANCE);
    }

 

Inside the ItemDenseMatterVessel class

    public class ItemDenseMatterVessel extends Item {

    public ItemDenseMatterVessel() {
        // UNIVERSAL_PREFIX is "quantumstorage:"
        setUnlocalizedName(Reference.UNIVERSAL_PREFIX + unlocalizedNameBase);
    }

}

Minecraft only loads one model per item by default, the name of this model is the item's registry name (the name passed to

GameRegistry.registerItem

or

Item#setRegistryName

). If you want to load a different model or multiple models, you need to call

ModelBakery.registerItemVariants

with the locations of those models.

 

I would highly recommend using Forge's

ModelLoader.setCustomModelResourceLocation

and

ModelLoader.setCustomMeshDefinition

methods in preInit instead of the vanilla

ItemModelMesher#register

overloads in init.

ModelLoader.setCustomModelResourceLocation

will call

ModelBakery.registerItemVariants

with the model location for you.

 

I would also recommend setting the registry names of your items with

Item#setRegistryName

and registering them with

GameRegistry.registerItem(Item)

. You can get an item's registry name in the

"modid:name"

format from

Item#getRegistryName

. This also applies to blocks.

 

I have a whole bunch of model registration code for my item models here. I use Forge's blockstates format and Java 8 features quite a lot in my mod.

I MISNAMED THE JSON FILE DAMMIT

 

Thanks for the suggestion Choonster.
