et je me ramaine a cette ligne la:

public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ)
   {
     playerIn.openGui(Main.instance, 3, worldIn, pos.getX(), pos.getY(), pos.getZ());
     return true;
   }

si une personne aurais une ider dous sa peux provenir sa me serais très utile sa fait des joure que je planche dessus et je ni arrive pas

Ah non au temps pour moi, j’ai mal lu le rapport de crash.

C’est un item de l’inventaire associé au gui qui est null.
Il faut utiliser des NonNullList en 1.12.

[TheXrayFR]

@robin4002

et comment on utilisa sa svp je débute un peut en java

[robin4002]

Regardes dans le code du tile entity du coffre.

[TheXrayFR]

ok je vais regarder

[TheXrayFR]

dans le tile ya pas de onBlockActivated

et dans la clase du block chest sa resemble a sa!

public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ)
    {
        if (worldIn.isRemote)
        {
            return true;
        }
        else
        {
            ILockableContainer ilockablecontainer = this.getLockableContainer(worldIn, pos);

            if (ilockablecontainer != null)
            {
                playerIn.displayGUIChest(ilockablecontainer);

                if (this.chestType == BlockChest.Type.BASIC)
                {
                    playerIn.addStat(StatList.CHEST_OPENED);
                }
                else if (this.chestType == BlockChest.Type.TRAP)
                {
                    playerIn.addStat(StatList.TRAPPED_CHEST_TRIGGERED);
                }
            }

            return true;
        }
    }
