Hello, New to modding, but have a solid CS foundation. I've created multiple custom BlockEntities that all have the same issue, which is that the inventory only updates on right click (overriding the useItemOn method). I've seen multiple posts on here outlining a similar issue to mine, but I've already implemented the solution of: overriding the correct methods in the BlockEntity class and calling setChanged(). I've tried every different place for setChanged() to no success. I'm wondering if I'm missing something else or if there was some change to sending data to the client in 1.21.5? Or will I have to use a custom packet sender? Here is the code for one of my BlockEntity classes with a single inventory slot: public class MyCustomBlockEntity extends BlockEntity { public final ItemStackHandler inventory = new ItemStackHandler(1) { @Override protected int getStackLimit(int slot, @NotNull ItemStack stack) { return 1; } @Override protected void onContentsChanged(int slot) { setChanged(); if (!level.isClientSide()) { level.setBlockAndUpdate(getBlockPos(), getBlockState()); } } }; public MyCustomBlockEntity(BlockPos pPos, BlockState pBlockState) { super(ModBlockEntities.MY_CUSTOM_BE.get(), pPos, pBlockState); } public void clearContents() { inventory.setStackInSlot(0, ItemStack.EMPTY); } public void dropItem() { SimpleContainer inv = new SimpleContainer(inventory.getSlots()); inv.setItem(0, inventory.getStackInSlot(0)); Containers.dropContents(this.level, this.worldPosition, inv); } @Override public void setRemoved() { dropItem(); super.setRemoved(); } @Override protected void saveAdditional(CompoundTag pTag, HolderLookup.Provider pRegistries) { super.saveAdditional(pTag, pRegistries); pTag.put("inventory", inventory.serializeNBT(pRegistries)); } @Override protected void loadAdditional(CompoundTag pTag, HolderLookup.Provider pRegistries) { super.loadAdditional(pTag, pRegistries); inventory.deserializeNBT(pRegistries, pTag.getCompound("inventory").get()); } @Override public Packet<ClientGamePacketListener> getUpdatePacket() { return ClientboundBlockEntityDataPacket.create(this); } @Override public CompoundTag getUpdateTag(HolderLookup.Provider pRegistries) { return saveWithoutMetadata(pRegistries); } } Mostly encountering the issue when calling the clearContents() method anywhere outside of useItemOn() in the Block class. I've also tried overriding both the handleUpdateTag() and onDataPacket() methods, calling their super along with loadAdditional(), but neither changed the outcome. Thanks in advance for any replies. -

I've just started modding, and I'm trying to make custom swords. When I try to import SwordItem, I get the error: What confuses me is that other item classes work fine: package io.github.xxx.denseswords.item; import io.github.xxx.denseswords.DenseSwords; import net.minecraft.world.item.Item; // works fine import net.minecraft.world.item.ShovelItem; // works fine import net.minecraft.world.item.SwordItem; // Error: The import cannot be resolved import net.minecraftforge.registries.DeferredRegister; import net.minecraftforge.registries.RegistryObject; Forge MDK v55.0.15 - Minecraft 1.21.5 Java v24.0.1 Windows 11 IDE: Visual Studio Code -

Any forge run instance of minecraft I run, regardless of mods or none can't seem to connect to a server, or my microsoft account. I tried redownloading forge and minecraft, restarting the computer, turning the firewall and antivirus off entirely, flushed my DNS cache, but nothing seems to work. -
