I am trying to figure out the 1.8 item rendering thing but get a null pointer exception with this line:

 

Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0, new ModelResourceLocation(References.MODID + ":" + item.getUnlocalizedName().substring(5), "inventory"));

 

Mod class:

 

@Mod(name = References.NAME, modid = References.MODID, version = References.VERSION)
public class ExampleMod
{
    @SidedProxy(clientSide = "com.example.examplemod.ClientProxy", serverSide = "com.example.examplemod.CommonProxy")
    public static CommonProxy proxy;
    
    @Instance(References.MODID)
    public static ExampleMod modInstance;
    
    @EventHandler
    public void preInit(FMLPreInitializationEvent e)
    {
    	TutorialItems.init();
    	TutorialItems.register();
    }
    
    @EventHandler
    public void init(FMLPreInitializationEvent e)
    {
    	proxy.render();
    }
    
    @EventHandler
    public void postInit(FMLPreInitializationEvent e)
    {
    	
    }
}

 

Items class:

 

public class TutorialItems 
{
public static Item test_item;

public static void init()
{
	test_item = new Item().setUnlocalizedName("test_item");	
}

public static void register()
{
	GameRegistry.registerItem(test_item, test_item.getUnlocalizedName().substring(5));
}

public static void registerRenders()
{
	registerRender(test_item);
}

public static void registerRender(Item item)
{
	Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(item, 0, new ModelResourceLocation(References.MODID + ":" + item.getUnlocalizedName().substring(5), "inventory"));
}
}

 

Client proxy:

 

public class ClientProxy extends CommonProxy 
{
@Override
public void render() 
{
	TutorialItems.registerRenders();
}
}

Null pointer, I will edit it too. It happens whenever I launch the game.

That may have had an effect...

 

Now just having this issue when loading the game:

 

[18:39:02] [Client thread/ERROR] [FML]: Model definition for location example:test_item#inventory not found

 

The Json file should be under src/main/resources/assets/modid/models/item and the texture under src/main/resources/assets/modid/textures/items, right?
