[1.11] Updating Issues

Recommended Posts

Hey guys,

today i went about attempting to update my wip mod to 1.11, and have successfully done so for the most part, but am running into a few issues while updating my Pulverizer.

Issue #1, The GUI,

in 1.10.2 it was all working just fine, upon updating, i ran into a few errors with my transferStacInSlot

1.10.2:

@Nullable
    public ItemStack transferStackInSlot(EntityPlayer playerIn, int index)
    {
        ItemStack itemstack = null;
        Slot slot = (Slot)this.inventorySlots.get(index);

        if (slot != null && slot.getHasStack())
        {
            ItemStack itemstack1 = slot.getStack();
            itemstack = itemstack1.copy();

            if (index == 2)
            {
                if (!this.mergeItemStack(itemstack1, 3, 38, true))
                {
                    return null;
                }

                slot.onSlotChange(itemstack1, itemstack);
            }
            else if (index != 1 && index != 0)
            {
                if (RecipePulverizer.instance().getPulverizingResult(itemstack1) != null)
                {
                    if (!this.mergeItemStack(itemstack1, 0, 1, false))
                    {
                        return null;
                    }
                }
                else if (index >= 3 && index < 30)
                {
                    if (!this.mergeItemStack(itemstack1, 30, 38, false))
                    {
                        return null;
                    }
                }
                else if (index >= 30 && index < 38 && !this.mergeItemStack(itemstack1, 3, 30, false))
                {
                    return null;
                }
            }
            else if (!this.mergeItemStack(itemstack1, 3, 38, false))
            {
                return null;
            }
             
            if (itemstack1.stackSize == 0)
            {
                slot.putStack((ItemStack)null);
            }
            else
            {
                slot.onSlotChanged();
            }

            if (itemstack1.stackSize == itemstack.stackSize)
            {
                return null;
            }

            slot.onPickupFromSlot(playerIn, itemstack1);
        }

        return itemstack;
    }

so i tried looking at the furnace container and the method it was using was such:

public ItemStack transferStackInSlot(EntityPlayer playerIn, int index)
    {
        ItemStack itemstack = ItemStack.field_190927_a;
        Slot slot = (Slot)this.inventorySlots.get(index);

        if (slot != null && slot.getHasStack())
        {
            ItemStack itemstack1 = slot.getStack();
            itemstack = itemstack1.copy();

            if (index == 2)
            {
                if (!this.mergeItemStack(itemstack1, 3, 39, true))
                {
                    return ItemStack.field_190927_a;
                }

                slot.onSlotChange(itemstack1, itemstack);
            }
            else if (index != 1 && index != 0)
            {
                if (!RecipePulverizer.instance().getPulverizingResult(itemstack1).func_190926_b())
                {
                    if (!this.mergeItemStack(itemstack1, 0, 1, false))
                    {
                        return ItemStack.field_190927_a;
                    }
                }
                else if (TileEntityFurnace.isItemFuel(itemstack1))
                {
                    if (!this.mergeItemStack(itemstack1, 1, 2, false))
                    {
                        return ItemStack.field_190927_a;
                    }
                }
                else if (index >= 3 && index < 30)
                {
                    if (!this.mergeItemStack(itemstack1, 30, 39, false))
                    {
                        return ItemStack.field_190927_a;
                    }
                }
                else if (index >= 30 && index < 39 && !this.mergeItemStack(itemstack1, 3, 30, false))
                {
                    return ItemStack.field_190927_a;
                }
            }
            else if (!this.mergeItemStack(itemstack1, 3, 39, false))
            {
                return ItemStack.field_190927_a;
            }

            if (itemstack1.func_190926_b())
            {
                slot.putStack(ItemStack.field_190927_a);
            }
            else
            {
                slot.onSlotChanged();
            }

            if (itemstack1.func_190916_E() == itemstack.func_190916_E())
            {
                return ItemStack.field_190927_a;
            }

            slot.func_190901_a(playerIn, itemstack1);
        }

        return itemstack;
    }

i tried implementing this into my container thinking i would have the same result, but no

#1 shift click give me:

[14:18:56] [server thread/INFO] [FML]: The state engine was in incorrect state SERVER_STOPPING and forced into state SERVER_STOPPED. Errors may have been discarded.

#2 placing an item in the slot also results in the same error

the second issue was opening the gui, when i right click my Pulverizer it seems as though its placing a second one in front of it, which is really weird, cant seem to figure out whats the cause of that.

Another issue is simply breaking it. Once broken it appears to have broken but right clicking that area opens up its gui and you have to break it again for it to be removed.

I haven't messed with 1.11, but it seems like you can't pass in a

null

anymore. Instead, use

ItemStack.field_190927_a

, which (I think) is an

ItemStack

of the air block.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

That's super weird. Why would they change that?

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

I have no clue, but probably to reduce NPEs...

 

That also means every null-check you have won't work. There's a new method in

ItemStack

you have to use. Look at the vanilla code to figure out how that method is called.

Seems you were right, after changing them to ItemStack.field_190927_a, i ended up with this:

        ItemStack itemstack = ItemStack.field_190927_a;

            itemstack = itemstack1.copy();

            if (index == 2)
            {
                if (!this.mergeItemStack(itemstack1, 3, 38, true))
                {

                    }

            else
            {
                slot.onSlotChanged();
            }

            if (itemstack1.func_190916_E() == itemstack.func_190916_E())
            {

            }

            slot.func_190901_a(playerIn, itemstack1);
        }

}

Shift clicking fixed, but placing an item in a slot still is not,

How im setting my recipes \/ \/ \/

        }else {
        	
        }
}

First of all, what is

pulverizerItemStacks

? It doesn't look like an

IItemHandler

, which you should use using together with the

Capability

system.

The way i used to set my recipes in 1.10.2 was basically the way the Furnace did it, updating to 1.11 i used the furnace again for reference to that. pulverizerItemStacks is:

    private NonNullList<ItemStack> pulverizerItemStacks = NonNullList.<ItemStack>func_191197_a(2, ItemStack.field_190927_a);

I have no clue, but probably to reduce NPEs...

 

On the other hand, it means (potentially) being able to toss item stacks of Air into the world, stacking them in your inventory, or pulling them out of the crafting grid.  You'd have to do more work to prevent this, than I imagine you'd save by handling null correctly.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

It's fine if you want to look at the vanilla furnace for help, that's fine. But in this case, it isn't. The

Capability

is a system Forge added to allow better compatibility between mods. Most mods aren't checking for

IInventory

anymore, so if you use it, most mods with e.g. item pipes won't work with your blocks.

 

There's a good explanation on

Capabilities

at mcforge.readthedocs.io.

 

I have no clue, but probably to reduce NPEs...

 

On the other hand, it means (potentially) being able to toss item stacks of Air into the world, stacking them in your inventory, or pulling them out of the crafting grid.  You'd have to do more work to prevent this, than I imagine you'd save by handling null correctly.

 

As far as I could tell from cpw's stream, vanilla has checks (e.g. stacksize == 0 or item==air) in the

ItemStack

class and handle that appropriately. This means you, as the modder, probably won't have to deal with air stacks.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

I think that stackSize is now a private field, so you need to replace it with one of its (SRG) getter methods (if you even continue to use it).

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

What is the point of a private field with both methods to get the current value and modify the current value?

That is, what is protected against that having the field public not protect against?

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Keep API consistency. If, in the future, you need to do something when the value is changed, you must have a getter/setter. You cannot do that without breaking API compatibility if the field used to be public.

This is the case here, the setter does more than just set the field.

 

Makes sense.  I didn't know that it did more than just set the value.
