Recommended Posts

Heyyy, i try to make a block that drops the most of all the items in my mod (~100), but whats the easiest way to do this?

 

Thats my current way, but to much work for all my items..  Anyone an idea?:

 

    @Override
    public Item getItemDropped(IBlockState state, Random rand, int fortune) {
        switch(rand.nextInt(6)){
        case 1:
            return Item1;
        case 2:
            return Item2;
        case 3:
            return Item3;
        case 4:
            return Item4;
        case 5:
            return Item5;
        default:
            return Item6;
        }
    }

You can create a public list in your item registry and add all of your items (at least those you want to be dropped from that item) ot that list while registering them. You can then select a random item from that list. I think it's propably the fastest way.

You can't. 

At some point, somewhere, you have to specify what you want dropped. 

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.

If you're lazy you can use this to obtain all Items added by your mod. But don't do this every time, do it once and store it in a field

 

List<Item> myItems = ForgeRegistries.ITEMS.getValues().stream()
  .filter(it -> it.getRegistryName().getResourceDomain().equals("yourmod"))
  .collect(Collectors.toList());

Ahem.

 

Yes, i tried this:

 

     int index = rand.nextInt(myItems.size());
            Item item = myItems.get(index);
            return item;

 

but the console says:

 

java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: bound must be positive

I don't know why. You wrote the code and you have not posted it.

 

public class BlockBox extends Block {
    List<Item> myItems = ForgeRegistries.ITEMS.getValues().stream().filter(it -> it.getRegistryName().getResourceDomain().equals("ageofweapons")).collect(Collectors.toList());

 

    public BlockWeaponBox() {
        super(Material.WOOD);
        this.setCreativeTab(ModTabs.generalTab);
        this.setHardness(0.5F);
        this.setResistance(1.0F);
        this.setSoundType(SoundType.WOOD);       

    }

    
   
    
    @Override
    public Item getItemDropped(IBlockState state, Random rand, int fortune) {
         int index = rand.nextInt(myItems.size());
            Item item = myItems.get(index);
            return item;
        
    }

You can't put it there, that's why. No items exist when that list is created.
