[Script✓] CFRU scripting - How to make a form change item?

[benicioneto]

Hello everyone,

I'm having some dificulty to understand what i should do to make a Gracidea, DNA Splicer ... item.

I'm using CFRU!

I know this code in "src > party_menu.c":
static void ItemUseCB_FormChangeItem(u8 taskId, TaskFunc func)
{
struct Pokemon* mon = &gPlayerParty[gPartyMenu.slotId];
u16 item = Var800E;
u16 species = GetMonData(mon, MON_DATA_SPECIES2, NULL);

PlaySE(SE_SELECT);
switch (item) {
case ITEM_GRACIDEA:
#if (defined SPECIES_SHAYMIN && defined SPECIES_SHAYMIN_SKY)
if (species == SPECIES_SHAYMIN)
{
species = SPECIES_SHAYMIN_SKY;
DoItemFormChange(mon, species);
gTasks[taskId].func = func;
}
else
#endif
goto NO_EFFECT;
break;
case ITEM_REVEAL_GLASS:
switch (species) ... {


That come from this in "src > party_menu.c":
void FieldUseFunc_FormChangeItem(u8 taskId)
{
gItemUseCB = ItemUseCB_FormChangeItem;

if (gTasks[taskId].data[3] == 0) //From Bag
{
SetUpItemUseCallback(taskId);
}
else //From Overworld
{
FadeScreen(FADE_TO_BLACK, 0);
gTasks[taskId].func = FormChangeItem_ShowPartyMenuFromField;
}
}

And there is this code in "routinepointers":
ifdef UNBOUND
FieldUseFunc_MaxPowder 8876C40
FieldUseFunc_Honey 8876E7C
FieldUseFunc_EVReducingBerry 8877C68
FieldUseFunc_EVReducingBerry 8877C94
FieldUseFunc_EVReducingBerry 8877CC0
FieldUseFunc_EVReducingBerry 8877CEC
FieldUseFunc_EVReducingBerry 8877D18
FieldUseFunc_EVReducingBerry 8877D44
FieldUseFunc_VsSeeker 887A054
FieldUseFunc_FormChangeItem 887BE3C
FieldUseFunc_FormChangeItem 887BE68
FieldUseFunc_FormChangeItem 887BE94
FieldUseFunc_FormChangeItem 887BE10
FieldUseFunc_FormChangeItem 887CC54
FieldUseFunc_FormChangeItem 887CC80
FieldUseFunc_FormChangeItem 887CCAC
FieldUseFunc_FormChangeItem 887CCD8
FieldUseFunc_FormChangeItem 887D308
FieldUseFunc_FormChangeItem 887D334
FieldUseFunc_AbilityCapsule 8877168
FieldUseFunc_AbilityCapsule 887CA9C
endif


And i know that i need to set a fieldeffect:
+"DNA SPLICERS", 720, 0, None, 0, <3DAFD6>, 0, 0, key, 4, <null>, 0, <null>, 0

So how i do config Gracidea item and make it work?
