If you want to know all Item's name in the game,
extract the APK and then
go to assets/image/items and voila all item ingame Currently Used is located here, and to find using GG just do
Ingame ID: scrap_metal
Image Name: scrap_metal.png
Length: 11 ( how to find out it 11, just count the total chars on the item ID/Name on folder i said earlier, excluding .png)
The query will be
QUERY : 11D;0D;Q 'scrap_metal':20
TYPE : Any
if do correctly, you'll get usually roughly 3 address or so and they're ordered, example
11 Dword
0 Dword
<some number> Qword
now, just click the QWORD address and click GO TO on the pop out, and determine if the address looks like a usual Game ID Structrures, if so the, just move upwards a bit. Use the 11D on memory view as reference and offset it by 4 address above,
if correct, the offset-ed address should be either 0 or a purple pointer. and that's your Item's ID
Note: This is useful for searching item that you don't have.
DISCLAMER: Some Items aren't available on the game, such as cypress and katana, etc.
I assume the devs adds these sprite for future content, and also some items are removed from the game.
