Posted November 24, 20177 yr I made a TileEntity with 1 slot. When I do things with the slot normally, it works. But when loading the world, the slot is buggy until I empty the slot, leave the GUI, and insert the item back. I also get an error message when loading the mod. @Override public void setInventorySlotContents(int slot, ItemStack stack) { if (slot > getSizeInventory() || slot < 0) return; if (stack != null && stack.stackSize > this.getInventoryStackLimit()) stack.stackSize = this.getInventoryStackLimit(); if (stack != null && stack.stackSize == 0) stack = null; this.slots[slot] = stack; if(getStackInSlot(0) != null){ worldObj.setBlockMetadataWithNotify(xCoord, yCoord, zCoord, getStackInSlot(0).getItemDamage() + 1, 2); }else{ worldObj.setBlockMetadataWithNotify(xCoord, yCoord, zCoord, 0, 2); } this.markDirty(); } @Override public void readFromNBT(NBTTagCompound tag) { super.readFromNBT(tag); NBTTagList list = tag.getTagList("Items", 10); for (int i = 0; i < list.tagCount(); ++i) { NBTTagCompound stackTag = list.getCompoundTagAt(i); ItemStack item = ItemStack.loadItemStackFromNBT(stackTag); int slot = stackTag.getByte("Slot") & 255; System.out.println(slot + "/" + item); this.setInventorySlotContents(slot, item); } } @Override public void writeToNBT(NBTTagCompound tag) { super.writeToNBT(tag); NBTTagList list = new NBTTagList(); for (int i = 0; i < this.getSizeInventory(); ++i) { if (this.getStackInSlot(i) != null) { NBTTagCompound stackTag = new NBTTagCompound(); stackTag.setByte("Slot", (byte) i); this.getStackInSlot(i).writeToNBT(stackTag); list.appendTag(stackTag); } } tag.setTag("Items", list); } that is my code. The error message is this: A TileEntity waterGenerator(com.deerangle.tile.TileEntityWaterGen) has thrown an exception during loading, its state cannot be restored.
