Hey guys, I'm trying to figure out how to get items to drop. I'm new to modding, and even following tutorials my items wont drop from a test block. Funnily, vanilla items do drop. I am unsure as to whether this is an issue with my items or blocks registries, or the test block itself. I was able to get the modded item to drop by changing 

    @Override
    public Item getItemDropped(IBlockState blockState, Random random, int fortune){
        return drop;
    }

from BlockTestDrops to

    @Override
    public Item getItemDropped(IBlockState blockState, Random random, int fortune){
        return ModItems.ripariusShard;
    }

While it works, it seems inefficient to bloat the blocks package by creating new classes for each block I want to have item drops. 

Here are the relevant classes:

ModItems

Any help would be greatly appreciated

Blocks are created and registered before Items, so you can't pass an Item to a Block constructor. When you create your Block instance, your Item fields haven't been initialised yet; so they still contain null.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Alright, that makes sense. I'm feeling pretty dumb here, is there something wrong with this preinit from the CommonProxy?

    @EventHandler
    public void preInit(FMLPreInitializationEvent event){
        File directory = event.getModConfigurationDirectory();
        config =new Configuration(new File(directory.getPath(),"TiberianEclipse.cfg"));
        ModItems.init();
        ModBlocks.init();
        ModRecipes.init();
        ModEntities.init();
        ModBiome.registerBiomes();

Blocks should be created and registered before Items. Apart from that, I can't see any obvious problems. What makes you think something is wrong?

 

I highly recommend migrating to registry events, they allow you to register things at the right time without worrying about when that is. This will also make it easier to update to 1.12+, where GameRegistry.register is private.

 

I recommend against having a common proxy; proxies are for sided code, common code belongs in your @Mod class (or classes called from it). I recommend using an interface as the common parent of your proxy classes rather than a common proxy class.

    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player. No player is mounted, or the passenger is not a player. No player is mounted, or the passenger is not a player. No player is mounted, or the passenger is not a player.
