Thanks for the link! I do not know if I had the right approach to implementing this idea, but so far I copied the AbstractChestedHorseEntity.java script and started to replace a lot of keywords with their PigEntity equivalent. I also copied a script for the container of the PigEntity and the screen of the PigEntity. Below will be the code: public abstract class AbstractChestedPigEntity extends PigEntity { private static final DataParameter<Boolean> DATA_ID_CHEST = EntityDataManager.createKey(com.educationalmoose.pighatmod.entity.passive.pig.AbstractChestedPigEntity.class, DataSerializers.BOOLEAN); protected AbstractChestedPigEntity(EntityType<? extends com.educationalmoose.pighatmod.entity.passive.pig.AbstractChestedPigEntity> type, World worldIn) { super(type, worldIn); } protected void registerData() { super.registerData(); this.dataManager.register(DATA_ID_CHEST, false); } public static AttributeModifierMap.MutableAttribute registerAttributes() { return registerAttributes().func_233815_a_(Attributes.field_233821_d_, (double)0.175F).func_233815_a_(Attributes.field_233830_m_, 0.5D); } public boolean hasChest() { return this.dataManager.get(DATA_ID_CHEST); } public void setChested(boolean chested) { this.dataManager.set(DATA_ID_CHEST, chested); } /** * Returns the Y offset from the entity's position for any entity riding this one. */ public double getMountedYOffset() { return super.getMountedYOffset() - 0.25D; } protected void dropInventory() { super.dropInventory(); if (this.hasChest()) { if (!this.world.isRemote) { this.entityDropItem(Blocks.CHEST); } this.setChested(false); } } public void writeAdditional(CompoundNBT compound) { super.writeAdditional(compound); compound.putBoolean("ChestedPig", this.hasChest()); if (this.hasChest()) { ListNBT listnbt = new ListNBT(); compound.put("Items", listnbt); } } /** * (abstract) Protected helper method to read subclass entity data from NBT. */ public void readAdditional(CompoundNBT compound) { super.readAdditional(compound); this.setChested(compound.getBoolean("ChestedPig")); if (this.hasChest()) { ListNBT listnbt = compound.getList("Items", 10); } } public boolean replaceItemInInventory(int inventorySlot, ItemStack itemStackIn) { if (inventorySlot == 499) { if (this.hasChest() && itemStackIn.isEmpty()) { this.setChested(false); return true; } if (!this.hasChest()) { this.setChested(true); return true; } } return super.replaceItemInInventory(inventorySlot, itemStackIn); } /* public ActionResultType getEntityInteractionResult(PlayerEntity player, Hand hand) { ItemStack itemstack = player.getHeldItem(hand); if (!this.isChild()) { if (player.isSecondaryUseActive()) { this.openGUI(player); return ActionResultType.resultSuccessClient(this.world.isRemote); } } } */ public int getInventoryColumns() { return 1; } } @OnlyIn(Dist.CLIENT) public class PigInventoryScreen extends ContainerScreen<PigInventoryContainer> { private static final ResourceLocation PIG_GUI_TEXTURES = new ResourceLocation("textures/gui/container/pig.png"); /** The EntityPig whose inventory is currently being accessed. */ private final PigEntity pigEntity; /** The mouse x-position recorded during the last rendered frame. */ private float mousePosx; /** The mouse y-position recorded during the last renderered frame. */ private float mousePosY; public PigInventoryScreen(PigInventoryContainer p_i51084_1_, PlayerInventory p_i51084_2_, PigEntity p_i51084_3_) { super(p_i51084_1_, p_i51084_2_, p_i51084_3_.getDisplayName()); this.pigEntity = p_i51084_3_; this.field_230711_n_ = false; } protected void func_230450_a_(MatrixStack p_230450_1_, float p_230450_2_, int p_230450_3_, int p_230450_4_) { RenderSystem.color4f(1.0F, 1.0F, 1.0F, 1.0F); this.field_230706_i_.getTextureManager().bindTexture(PIG_GUI_TEXTURES); int i = (this.field_230708_k_ - this.xSize) / 2; int j = (this.field_230709_l_ - this.ySize) / 2; this.func_238474_b_(p_230450_1_, i, j, 0, 0, this.xSize, this.ySize); InventoryScreen.drawEntityOnScreen(i + 51, j + 60, 17, (float)(i + 51) - this.mousePosx, (float)(j + 75 - 50) - this.mousePosY, this.pigEntity); } public void func_230430_a_(MatrixStack p_230430_1_, int p_230430_2_, int p_230430_3_, float p_230430_4_) { this.func_230446_a_(p_230430_1_); this.mousePosx = (float)p_230430_2_; this.mousePosY = (float)p_230430_3_; super.func_230430_a_(p_230430_1_, p_230430_2_, p_230430_3_, p_230430_4_); this.func_230459_a_(p_230430_1_, p_230430_2_, p_230430_3_); } } public class PigInventoryContainer extends Container implements IForgeRegistryEntry<PigInventoryContainer> { private final IInventory pigInventory; private final PigEntity pig; public PigInventoryContainer(int p_i50077_1_, PlayerInventory playerInventory, IInventory hatPigInventory, final PigEntity hatPig) { super((ContainerType<?>)null, p_i50077_1_); this.pigInventory = hatPigInventory; this.pig = hatPig; int i = 3; hatPigInventory.openInventory(playerInventory.player); int j = -18; this.addSlot(new Slot(hatPigInventory, 0, 8, 18) { public int getSlotStackLimit() { return 1; } }); for(int i1 = 0; i1 < 3; ++i1) { for(int k1 = 0; k1 < 9; ++k1) { this.addSlot(new Slot(playerInventory, k1 + i1 * 9 + 9, 8 + k1 * 18, 102 + i1 * 18 + -18)); } } for(int j1 = 0; j1 < 9; ++j1) { this.addSlot(new Slot(playerInventory, j1, 8 + j1 * 18, 142)); } } /** * Determines whether supplied player can use this container */ public boolean canInteractWith(PlayerEntity playerIn) { return this.pigInventory.isUsableByPlayer(playerIn) && this.pig.isAlive() && this.pig.getDistance(playerIn) < 8.0F; } /** * Handle when the stack in slot {@code index} is shift-clicked.

The main problem I have right now is when I try to register the container, I followed a 1.15 tutorial for registering a container and it does not seem to be compatible with the PigInventoryContainer script because PigEntity cant be accessed ublic class ModContainerTypes { public static final DeferredRegister<ContainerType<?>> CONTAINER_TYPES = DeferredRegister.create(ForgeRegistries.CONTAINERS, PigHatMod.MOD_ID); public static final RegistryObject<ContainerType<PigInventoryContainer>> PIG_INVENTORY_CONTAINER = CONTAINER_TYPES.register("pig_inventory_chest", () -> IForgeContainerType.create(PigInventoryContainer::new)); } @Mod.EventBusSubscriber(modid = PigHatMod.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public class ClientEventBusSubscriber extends AnimalEntity { protected ClientEventBusSubscriber(EntityType<? extends AnimalEntity> type, World worldIn) { super(type, worldIn); } @SubscribeEvent public static void clientSetup(FMLClientSetupEvent event) { ScreenManager.registerFactory(ModContainerTypes.PIG_INVENTORY_CONTAINER.get(), PigInventoryScreen:: new); } @Nullable @Override public AgeableEntity func_241840_a(ServerWorld p_241840_1_, AgeableEntity p_241840_2_) { return null; } }

I just started modding a few weeks ago and I am new to forge but have at least a basic understanding of Java programming. I am self taught but know the basics and am constantly trying to improve. Anyways, I wanted to learn how to use containers, inventories, etc. and I noticed a lack of information newer than 1.14 and was having a lot of difficulty following tutorials online. For this specific mod, I was trying to start off super basic and just make an inventory with 2 slots, but I wanted to put the inventory on an entity that already exists within minecraft, because I thought it would be easier than creating my own entity. I decided to use the pig, and so far I have been basing almost all of my code off of the horse entity. I have come across many problems though and I do not know where to find an answer since there is not much documentation on this. I have been learning a lot about tileEntities and I was going to try making a chest with 2 inventory slots and then just opening that chest whenever I click on a pig, but this seems like an inefficient way to go about doing this. Unfortunately since I am new to modding I do not know all of the different possible ways to accomplish this and I was wondering if someone could help me a little bit so I can get on my way. I will supply people with any code that they might need to see to help me out, and I am using IntelliJ. Thanks!
