New Items Only Glitching

I ran into this before and I swore I had it ironed out, but not so much apparently.
I added a string of new items early on, and went back in and added a new string of items.
Successfully added data to:
- items.asm, for the identifiers and functions
- itemprices.asm, for the new items
- item_names.asm
- key_items.asm (which was my issue the first time)

The new items are potion items, the code for their function works just fine, but upon the use, the screen reverts to the menu and my first position party member remains visible. When I close out the menu, all of the sprites disappear. If I move, it can lock up. If I pull up my party menu and back out, everything comes back and works perfectly.
The displaced potion items work perfectly. Other items work fine. Just these new ones do not.

Items that pull up the party menu need to be added to the list in engine/menu/start_sub_menus.asm and I see you didn't list that as a file you edited, so I'd give that a try. That seems to be the only thing you're missing, looking back at the commit where I added berry items.

Re: New Items Only Glitching

Yup, that does the trick! And it appears I had *that* part down the first time as my first such item is on that list :D
Joys of being away from a code base this long I suppose~
Thanks!

Re: New Items Only Glitching

New element in the ongoing saga:
The new item, with one item in the back pack, shows the quantity; additional copies of the item and the quantity (x2, x3, etc) disappears. It stacks, it just doesn't SHOW its stacking.

Re: New Items Only Glitching

Still can't sort the stacking issue...

Here's my key_items.asm file: 

KeyItemBitfield: ; e799 (3:6799) ;1 = Not a key item ;0 = Key Item or not-stackable item
    db %11110000
    db %00000001
    db %11110000
    db %01001111

Now, I am confused on something...Moon Stone is stackable isn't it? So why does it not show as stackable? And does that have anything to do with why my RKT POTION item is not stackable?

Re: New Items Only Glitching

You know what...never mind I think. I must have the whole thing backwards looking at it.
0 must be a non-key, stackable item
1 must be a keyed item
And I knew elsewhere the byte read backwards but this seemed to line up with the inverted understanding of the items...except, now, I realize it doesn't...

AND I am dumber than I thought; there's a line in engine/items/items.asm that tells the game how many bytes to grab to view the bits...and my new items were failing because they were on a byte outside of the pulled range. Yay!

Re: New Items Only Glitching

Yeah, the bits are read right to left, so it's easy to get thrown off when you're used to reading everything left to right. And yeah, 0 is a normal item, 1 is a key item. Glad you got it figured out.

Re: New Items Only Glitching

What's funny is I'm *used* to the bytes reading backwards, but somewhere the note about the 1 being a normal item and 0 being a key item was there, and may have been inserted by me after the first go-round, so reading it back it looked like it was right, reading left to right, which seemed odd and out of place but oh well, some things behave weirdly... ^_^
