[1.15.2] Generating JSON Files isn't working; how to use ItemModelProvider ?


Recommended Posts

Hi guys!


I want to generate my json files within my code because it would take too long to do it all by hand.

Before noticing that forge provides some useful classes / interfaces, I wrote some code myself which I thought would work... but it doesn't.

I don't really know why, and I am super obwhelmed by forge's classes / interfaces for this purpose, so if someone would share some insight on ItemModelProvider and which methods are important, I'd be delighted!

Do I need a modelBuilder, modelLoader and modelProvider? What about the DataGenerator?


My code

The main mod class:



the init class with nested json:



my assets:



Thanks in advance!

I guess you're talking about json models for blocks or items?

If this is just a once-off thing, I would personally use Excel (with formulas to copy the right words into the right places in the file) and then export as text.


I would also get my mod working perfectly with just one item/block first.  And then when I had ironed out all the bugs, I would add all the remaining items/blocks.

Sorry for the late response!

Yes, it's for generating the object_name.json files!
Okay, I could do that, but in the long run I'd like to understand that as well.

I will definitely work on the core code of my mod before making more things, you're right.


Thanks for your answer,

    • I need to find out which part of the player model an arrow hits (Eg: Left-arm, right-leg) when the arrow hits the player. Any solutions / suggestions are welcome
    • Hello everyone, like the title suggest, I've a problem running dedicated server for my mod "emomod, Emotion's Mod", I understand that the problem is caused by my containers because of invalid dist and I understand the concept of side but I really struggle to fix it, for the lore I'm developing this mod since 5 or 6 years from now so it's a huge one, I have like 281 block textures, 167 item textures, biomes, game mechanics, dimensions, entities etc.. I love it but I kept it private for the moment (I may send it public soon) and I use to get back on it sometimes when I want to update the version (I also rewrite everything once because I suck to do so for the version 1.8 to 1.12 / 1.14) or add stuff for example, here is the log of the server :   I'm registering Biome, Block, ContainerType, TileEntityType etc.. In differents class that I'm calling in my main one called "MainRegistry" with the method init().   Firstly, the classe where I'm registering ContainerType is modestly named "ContainerTypeRegistry" (this is my convention), I've currently three type of container, "CRAFTER" wich is a complex automatic crafting machine, "BAG" is a bag item storing stuff using "ItemStackHandler" and finally Nightstand is a basic chest with less slots (4) using different color GUIs based on the wood used to craft, here is the code :   @Mod.EventBusSubscriber(modid = MainRegistry.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD) public class ContainerTypeRegistry { private static final List<ContainerType<?>> containerTypeList = new ArrayList<ContainerType<?>>(); public static final ContainerType<CrafterContainer> CRAFTER = IForgeContainerType.create((windowId, inv, data) -> { BlockPos pos = data.readBlockPos(); return new CrafterContainer(windowId, MainRegistry.proxy.getClientWorld(), pos, MainRegistry.proxy.getClientPlayer()); }); public static final ContainerType<BagContainer> BAG = IForgeContainerType.create((windowId, inv, data) -> { return new BagContainer(windowId, inv); }); public static final ContainerType<NightstandContainer> NIGHTSTAND = IForgeContainerType.create((windowId, inv, data) -> { BlockPos pos = data.readBlockPos(); return new NightstandContainer(windowId, inv.player.getEntityWorld(), pos, inv); }); public static void init() { addContainerType(CRAFTER, "crafter"); addContainerType(BAG, "bag"); addContainerType(NIGHTSTAND, "nightstand"); } public static void addContainerType(ContainerType<?> tet, String name) { containerTypeList.add(tet.setRegistryName(name)); } @SubscribeEvent public static void registerContainerType(final RegistryEvent.Register<ContainerType<?>> e) { for (ContainerType<?> tet : containerTypeList) { e.getRegistry().register(tet); } } } Secondly, I'm using the same technique to register TileEntityType and I'm calling all those init methods but also ScreenManager.registerFactory() like I said in the main class just here :   @Mod(MainRegistry.MOD_ID) public class MainRegistry { public static final String MOD_ID = "emomod"; public static final Logger LOGGER = LogManager.getLogger(MOD_ID); public static IProxy proxy = DistExecutor.runForDist(() -> () -> new ClientProxy(), () -> () -> new ServerProxy()); public static MainRegistry instance;

Thanks again for giving me some of your time, I can send the WIP version of the mod jar as demo when this will be fixed if some of you want it, and also if I find a way to protect my textures from being copied / reused or modified.

    • Only ModelRegistryEvent is necessary. Call ModelLoader.addSpecialModel in there and the model will be baked as normal.
