There is the problem right there, NPE at that packaged name, That file name, that method (filename.java: lineNumber)

 

Go to the specified line and see what is happening there, set a Breakpoint and see wtf is "null" in value when used. Then you have solved most of it already.

If you guys dont get it.. then well ya.. try harder...

thank your

i found the error but i am completely blank on how to fix it so for now i removed the code, for now... (it is not need for my mod to run any way)

 

the error is that i am with 99% change using a wrong way too detect when/if a server is running

 

        if(!initializedserver) {
            for (TickType ticktype : type) {
                if (ticktype == TickType.SERVER){
                    if (FMLServerHandler.instance().getServer().isDedicatedServer()) { <------- ERROR LINE HERE
                        if(ModConfigCore.ConfigLoadFail != false || ModConfigCore.ConfigLoadFailArmor != false){
                            initializedserver = true;
                            
                            if(ModConfigCore.ConfigLoadFail == true || ModConfigCore.ConfigLoadFailArmor == true){
                                FMLServerHandler.instance().getServer().logWarning(Strings.CONFIG_DIFFICULTY_INGAME_CHAT);
                            }
                        }
                    }
                }
            }
        }

dam i am sooo stupid :) thanks man it works now

 

how the code looks now

        if(!initializedserver) {
            for (TickType ticktype : type) {
                if (ticktype == TickType.SERVER){
                    if (FMLServerHandler.instance().getServer() != null) { <---- changed .isDedicatedServer() to != null
                        if(ModConfigCore.ConfigLoadFail != false || ModConfigCore.ConfigLoadFailArmor != false){
                            initializedserver = true;
                            
                            if(ModConfigCore.ConfigLoadFail == true || ModConfigCore.ConfigLoadFailArmor == true){
                                FMLServerHandler.instance().getServer().logWarning(Strings.CONFIG_DIFFICULTY_INGAME_CHAT);
                            }
                        }
                    }
                }
            }
        }

 

 

EDIT---

by the way when i tried to use my mod in normal minecraft i got a wired crash report

and i can see that it is something with the setUnlocalizedName

    • As the title says i keep on crashing on forge 1.20.1 even without any mods downloaded, i have the latest drivers (nvidia) and vanilla minecraft works perfectly fine for me logs: https://pastebin.com/5UR01yG9
    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
