Containers of different sizes via subclassing or variables


Daeruin

Recommended Posts

I created a tile entity with inventory and a GUI. It was challenging to my amateur programming skills. Now I want to create several more containers of different sizes. I made my tile entity into an abstract class and create two subclasses to override the getSizeInventory and getName methods. That has worked fine so far—at least my original container now works by using one of the subclasses I created. I still haven't built the additional GUI to handle the different number of slots of the other subclass, or registered the block or created the texture, etc.

 

What I'm wondering is if I can instead create a variable to represent the number of inventory slots, set it in the tile entity's constructor, and use it in getSizeInventory rather than using a hard-set int value. I started along that path but didn't get very far, so I'm not sure if I was just dumb to try or if I'm missing something. It would be cool if I didn't have to subclass my tile entity a dozen times for all the different containers I want to make.

Well obviously that is a yes but your constructor can't have any parameters, so a setter would work.

That's actually the first thing I tried. I assumed I could add a new field to my tile entity and pass the parameter into the constructor when returning a new tile entity in createNewTileEntity (in my container's block class). Why can't the constructor have any parameters?

 

If I used a setter, when and where would I invoke it?

It can have a constructor with parameters, but it must have one with none because when the game is loaded it must instantiate them from world data.

Hi

 

You can store information like that in the Tile Entity NBT

A working example is here

https://github.com/TheGreyGhost/MinecraftByExample

see mbe30

NUMBER_OF_SLOTS is a final int in this example, but you can load it from NBT like any other setting (see also mbe20 - TileEntityData for more examples of how to use NBT properly).

 

From memory, Vanilla does something similar when two side-by-side chests are combined together.

    • im stuck in a problem whit BlockEntities i cannot solve so im trying to work around it but in the less complex way possible  i think is posible to store data to the minecraft world  in older versions people talk about  WordDataSave i dont find anything about it for 1.20.4  i find a tutorial for player capability in 1.19    here is an event      //########## ########## ########## ##########     @SubscribeEvent     public static void onAttachCapabilitiesPlayer(AttachCapabilitiesEvent<Entity> event) {         if(event.getObject() instanceof Player) {             if(!event.getObject().getCapability(PlayerThirstProvider.PLAYER_THIRST).isPresent()) {                 event.addCapability(new ResourceLocation(mercmod.MOD_ID, "properties"), new PlayerThirstProvider());             }         }     }  soo i made this      //########## ########## ########## ##########     @SubscribeEvent     public static void onAttachCapabilitiesLevel(AttachCapabilitiesEvent<Level> event) {     } i think i can do some witchcraft  here  but is many things don't understand  to start whit i dont get yet how to recall the saved data from a BlockEntity  the handler still in progress the plan is to make a Map to store nbt data using the block coordinates as index later store that map as a big nbt      ########## any way the question is if theres alredy a tutorial for 1.20.4 for this ?? or some alredy working code from someone else doing something similar ?           
    • I tried this, and found out that Oculus is the mod that is crashing the game. I have removed it, and it now works fine! Thanks!
    • Hi @DanielderErbauer, I arrived here as I have the "as it does not exist in Block{minecraft:air}" error in a modpack I am trying to start. It's a long-shot, I know, but as the post that led this to being solved is missing, can I ask if you may recall what it said? Thanks in advance
    • Hm yeah sorry, not seeing anything else that's sticking out, I'd need to debug myself probably. Do you have a github or bitbucket repo? I could poke around when I have time to see what the problem might be.
    • looking around for the capabilities thing i found a piece of code and find this piece of code  //########## ########## ########## ########## @SubscribeEvent public static void addCustomTrades(VillagerTradesEvent event) { if(event.getType() == VillagerProfession.FLETCHER) { System.out.println("\n\n### VillagerProfession.FLETCHER \n\n");//<----------- Int2ObjectMap<List<VillagerTrades.ItemListing>> trades = event.getTrades(); ItemStack stack = new ItemStack(ItemInit.ARROW_STEEL.get(), 16); int villagerLevel = 1; trades.get(villagerLevel).add((trader, rand) -> new MerchantOffer( new ItemStack(Items.EMERALD, 2), stack,1,3,0.02F)); } if(event.getType() == VillagerProfession.TOOLSMITH) { System.out.println("\n\n### VillagerProfession.TOOLSMITH \n\n");//<----------- Int2ObjectMap<List<VillagerTrades.ItemListing>> trades = event.getTrades(); ItemStack stack = new ItemStack(ItemInit.INGOT_STEEL.get(), 1); int villagerLevel = 1; trades.get(villagerLevel).add((trader, rand) -> new MerchantOffer( new ItemStack(Items.EMERALD, 2), stack,10,8,0.02F)); } } //########## ########## ########## ########## the event is aknoledge and execute when the maps load  ### VillagerProfession.FLETCHER  ### VillagerProfession.TOOLSMITH  //########## But is not working      is a random piece of code is not working  could it be than this code is old 1.18 and no valid anymore for 1.20.4 or the thing are this numbers  stack,10,8,0.02F));  i dont know what this numbers means    ########## the question is ¿how to add things to the villager traders    thanks for your attention
