hi.

i still had a forge version on my computer that didn't have an internal modloader (so i also had modloader and modloaderMP installed)

 

now i updated my forge to version 3.3.7 (minecraftforge-client-3.3.7.135.zip) and removed modloader and modloaderMP

when i start minecraft, i get the following crash message:

 

  Reveal hidden contents

 

before anyone starts asking, i am using "MultiMC" to manage my mods

and everything worked fine before i updated the forge. so i guess the problem has to be that forge update

 

here's the ForgeModLoader-0.log

You're using a mod that requires MLMP, Don't, its crap.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

i am?

well, that's not good.

but i can't see any mod name in that error message. i guess i'll have to uninstall my mods one by one to find out wich one it is.

 

well, the problem is, that i am doing a "Let's Play" on youtube. and i as far as i would say, i need all the mods im using

ok, thanks for the help. i forgot to look for hints in the forgemodloader file

 

but unfortunately it isn't the only mod that couses the problem.

EXP chest seems to need modloaderMP as well.

 

that means i'll have to check for updates (and hope that modloaderMP isn't needed anymore) or try to live without those mods.

 

anyway, thanks for the nice support. i guess (hope) this thread can be closed/deleted/moved now.

    • Rubidium and Embeddium are versions of the same mod, you can only have one. I believe Embeddium is the one that's actively maintained.
    • 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'm just really confused. This bug only applies to modpacks made by me. i have tried using different launchers prism, modrinth etc. I have tried with multiple modpacks.

    • 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
