[1.15.2] How to make a JSON reader

Recommended Posts

Hi! So I'd like to add a new "type" of json file to modid/assets (EDIT: actually modid/data. Sorry). Obviously I know how to create folders and files, but how would I get my mod to read it? I've had a look at IRecipe, but I'm still not 100% sure how it gets called, etc.

I'm probably more excited than I should be for something so realistically minor...

You need a JsonReloadListener. Look at RecipeManager for a vanilla example or LootModifierManager for a forge example (works a little different though).

There is also something I wrote a while ago (in Kotlin and for 1.16, but it works the same), here.

 

Unfortunately it seems that 1.15 does not yet have the event to register these, so you have to use FMLCommonSetupEvent or something for it.

So I've created something that should work, but how exactly do I register it?

EDIT: Looking at other classes, I feel like I'd need to create my own registry. Am I correct?

To register the JsonReloadListener, you simply need to register it as a resource reload listener using addReloadListener.

Sorry if it's obvious, but what class does addReloadListener belong to?

IReloadableReloadListener

That class doesn't exist... The closest I found is IReloadableResourceManager, which eclipse can't seem to see any methods in.

IReloadableResourceManager is an interface, so that would be why. What do I do?

 

EDIT: About the shortcuts, I'll have a look at mine ;)

So, I've found
Minecraft.getInstance().getResourceManager(),
which returns resourceManager which is an IReloadableResourceManager. However,it returns it as an IResourceManager, which does not have the addReloadListener method. I've also found
MinecraftServer.getResourceManager(),
which does return an IReloadableResourceManager. I can get it using
Minecraft.getInstance().getIntegratedServer().getResourceManager().
Would this work on singleplayer though?

This will work ONLY in single player.

I think you need to use FMLServerAboutToStartEvent for this in 1.15.2, this will give you access to the that is just starting (whether integrated or dedicated).

    • I created an SOUL_JAR Item that has been registered for each mob like - mod:soul_jar_minecraft_cow etc.. but it all has different registry names, i have a model file name soul_jar.json and i want to know how to bind each of those items to this class (When mod iterates through all of vanilla mobs and registering items for them).   I didn't found any info about it because all of info is outdated, and forge docs is complicated asf (i wish there would be more examples) i also used AI but it showing me only outdated info, but theres some code where i registering my item and trying to bind it to model ->   public static void register(IEventBus eventBus){ ITEMS.register(eventBus); Set<ResourceLocation> entityKeyList = ForgeRegistries.ENTITY_TYPES.getKeys(); for (ResourceLocation k : entityKeyList) { EntityType<?> entityType = ForgeRegistries.ENTITY_TYPES.getValue(k); if (!entityType.getCategory().equals(MobCategory.MISC)) { RegistryObject<Item> SOUL_JAR = ITEMS.register("soul_jar" + '_' + k.toString().replace(':', '_').replace('.', '_'), () -> new JarItem(new Item.Properties().rarity(Rarity.RARE).tab(ModTabs.MAGICAL_OBSESSION_JARS), entityType)); if (Thread.currentThread().getThreadGroup() == SidedThreadGroups.CLIENT) { ItemModelShaper itemModelShaper = Minecraft.getInstance().getItemRenderer().getItemModelShaper(); itemModelShaper.register(SOUL_JAR.get().asItem(), new ModelResourceLocation("item.soul_jar", "inventory")); } } } } I also have more questions like how to iterate through all other mods mobs also, or render mob inside of a jar in inventory, but i will try to figure it out.
    • I looked into OctoEconomyAPI and saw that it was a JAR api for fabric. This means you have a fabric mod in your mods folder. I downloaded your mod folder and wasted 2 solid hours creating a Python script to try to find the faulty mod, and eventually just gave up. I suggest you create two installations with half or the mods in each, find which one doesn't launch, cut that one in half, and repeat until you find the fabric mod. Investigué OctoEconomyAPI y vi que era una API JAR para fabric. Esto significa que tienes un mod de Fabric en tu carpeta de mods. Descargué su carpeta de mods y desperdicié 2 horas completas creando un script de Python para tratar de encontrar el mod defectuoso, y finalmente me di por vencido. Le sugiero que cree dos instalaciones con la mitad o las modificaciones en cada una, encuentre cuál no se inicia, córtela por la mitad y repita hasta que encuentre la modificación Fabric.   (The Python script I made is here): (El script de Python que hice está aquí):  
    • I've got it to work now. Instead of using the texture manager I used the Render System:   RenderSystem.setShaderTexture(0, new ResourceLocation("mcaquests", "textures/item/questbook.png"));  
    • Hello ive been having the same issue over Curse Forge's auto modding or when i use manual modding. The error seems to be within either Oculus or Rubidium. Im using 1.19 with the latest 1.19 forge + 1.19 compatible Oculus and Rubidium. Just in case the versions i am using; Oculus - oculus-1.4.3a Rubidium - rubidium-0.6.3 Note: I tried removing the two and add Optifine and it opens without a problem. I didnt use all 3 together to get this error im talking tho, i know they are not compatible with optifine dont worry. Logs Debug The actual error code im getting on start-up is ''1'' and nothing else on the pop up box. I have tried finding the jar files on the internet and insert them on my own but that didnt go too far.
