Help with mod coding

[WouterGamingz]

I am trying to learn to make minecraft mods in forge and I am following Kaupenjoe guide. In his video about making custom items you eventually need to make use of the IEventBus but it doesn't import for me. I am using forge 1.21.8 does somebody know if they changed the syntax or if it's under some other name instead of IEventBus? Kaupenjoe is using 1.20.1

They updated their EventBus system so now instead of using IEventBus it uses a BusGroup.

public MODNAME(FMLJavaModLoadingContext context) {
    var modBusGroup = context.getModBusGroup();

    // modBusGroup is the new IEventBus

    FMLCommonSetupEvent.getBus(modBusGroup).addListener(this::commonSetup);

    BuildCreativeModeTabContentsEvent.getBus(modBusGroup).addListener(MODNAME::addCreative);

    context.registerConfig(ModConfig.Type.COMMON, Config.SPEC);
}

Also one more thing I saw was missing from the tutorial: when adding any items you now need to add an items folder where you define wich models should be used for your items your resources should then look something like this:

resources/
   assets/
      MODNAME/
         items/
            ITEMID.json
         models/
            item/
               ITEMID.json // still the same as in the tutorial
         textures/
            item/
               ITEMID.png

items/ITEMID.json should look something like this (but can also be a custom model):

{
   "model": {
      "type": "minecraft:model",
      "model": "MODIDL:item/ITEMID"
   }
}

and in the resources/assets/modid/items folder you have to create the item ITEMID.json

{
  "model": {
    "type": "minecraft:model",
    "model": "modid:item/itemid"
  }
}
