I was watching team aqua hideout video on adding the pokevial, but it seems outdated, nothing worked, is there a new method to adding new items if im keeping the icons and palettes?
I don't know what does that video show, but the process of adding items is exactly the same as it is in Pret's repository.
- You define a constant label for your item before
ITEMS_COUNT
in
include/constants/items.h
.
- You add the basic data for your item in
src/data/items.h
according to your needs.
- You add a description for it in
src/data/text/item_descriptions.h
(though that file will eventually be phased out)
And then the rest kinda depends on what exactly you want to do.
If you want to add an effect that can be triggered by using the item, you're going to have to assign a
fieldUseFunc
to your item.
You can use any of the existing ones as a reference point, but the short version is that you define an OutOfBattle function in
include/item_use.h
, declare it in
src/item_use.c
and then you write a function to perform whatever you want, either on that same file or in a different one such as
src/party_menu.c
, again, according to your needs and wants.
If you want to add a held item effect for battles, you'll have to define a constant label in
include/contants/hold_effects.h
that you obviously need to assign to your item in
src/data/items.h
, and then you'll have to make use of said label in whatever battle system related function you deem it convenient to your goals.
Could be
ItemBattleEffects
in
src/battle_util.c
, could be
Cmd_critcalc
in
src/battle_script_commands.c
, etc.
