I need to return 2 values from a spell being cast...

What Level the Spell is...

&

What Spell School the spell being cast is...

Is there a function that will return this?

[Shadooow]

This is snippet from community patch 1.70, it contains both you need using Get2DAString:

//private function
//1.70 by Shadooow: Is my target immune to last spell cast?

So Basically...

This..

 if(nSpellLevel == 99)
 {
 string sCollumn = "Innate";
  switch(nclass)
  {
  case class_TYPE_WIZARD:
  case class_TYPE_SORCERER:     sCollumn = "Wiz_Sorc";  break;
  case class_TYPE_CLERIC:       sCollumn = "Cleric";    break;
  case class_TYPE_DRUID:        sCollumn = "Druid";     break;
  case class_TYPE_BARD:         sCollumn = "Bard";      break;
  case class_TYPE_RANGER:       sCollumn = "Ranger";    break;
  case class_TYPE_PALADIN:      sCollumn = "Paladin";   break;
  }
 sCollumn = Get2DAString("spells",sCollumn,nSpellId);
  if(sCollumn != "****" && sCollumn != "")
  {
  nSpellLevel = StringToInt(sCollumn);
   if(bAOE) SetLocalInt(OBJECT_SELF,"AOE_INNATE",nSpellLevel+1);
  }
 }
int nMaxLevel;
 if(GetHasSpellEffect(734,oTarget))
 nMaxLevel = 8;
 else if(GetHasSpellEffect(SPELL_GLOBE_OF_INVULNERABILITY,oTarget))
 nMaxLevel = 4;
 else
if(GetHasSpellEffect(SPELL_MINOR_GLOBE_OF_INVULNERABILITY,oTarget) ||
GetHasSpellEffect(SPELL_GREATER_SHADOW_CONJURATION_MINOR_GLOBE,oTarget))
 nMaxLevel = 3;
 else if(GetHasSpellEffect(SPELL_ETHEREAL_VISAGE,oTarget))
 nMaxLevel
=
2;                                                                                                                         
//shadow ghostly visage
 else
if(GetHasSpellEffect(SPELL_GHOSTLY_VISAGE,oTarget) ||
GetHasSpellEffect(SPELLABILITY_AS_GHOSTLY_VISAGE,oTarget) ||
GetHasSpellEffect(SPELL_GREATER_SHADOW_CONJURATION_MIRROR_IMAGE,oTarget))
 nMaxLevel = 1;
 if(nSpellLevel <= nMaxLevel)
 {
 return TRUE;//immunity via spell immunity effect like globe of invulnerability
 }
string sSchool = Get2DAString("spells","School",nSpellId);
 if(GetHasSpellEffect(SPELL_SHADOW_SHIELD,oTarget) && sSchool == "N")
 {
 return TRUE;//Necromantic spell cast at target with Shadow Shield
 }
 else if(GetHasSpellEffect(390,oTarget) && sSchool == "E")
 {
 return TRUE;//Enchantment spell cast at target polymorphed into pixie
 }
int nSchool = -1;
 if     (sSchool == "A")     nSchool = 0;
 else if(sSchool == "C")     nSchool = 1;
 else if(sSchool == "D")     nSchool = 2;
 else if(sSchool == "E")     nSchool = 3;
 else if(sSchool == "V")     nSchool = 4;
 else if(sSchool == "I")     nSchool = 5;
 else if(sSchool == "N")     nSchool = 6;
 else if(sSchool == "T")     nSchool = 7;
 if(bAOE && !GetIsPC(oTarget))
 {
  if(bNoChange && GetLocalInt(oTarget,"IMMUNE_TO_"+IntToString(nSpellId)) == -1)
  {
  return FALSE;//immunity to AOE is not granted via itemproperty, no reason to repeat whole process again
  }
  else
  {
  SetLocalObject(oTarget,"ITEM_IN_RIGHT",oRight);
  SetLocalObject(oTarget,"ITEM_IN_LEFT",oLeft);
  }
 }

& This

string sSchool = Get2DAString("spells","School",nSpellId);

Correct?

I was really looking for exact help (as in complete function), if you would be willing to do that ShadoOow?

One other question, would 2da String Lookup be slow????

I'm thinking it would be better to just like use a switch/case statement with all of the spells listed in each case, for speed, or would this be slow too?

[Shadooow]

2DA lookups were slow before 1.69 but now this is automatically cached in engine. But even if it would be slow - how often you want to do it and where you want to do it?

You and not only you, are probably too obsessed with efficiency while you don't care about default AI scripts that run every second. General PW module with hundred areas will run thousands scripts each second, in this manner one script that runs one time when player rest or equip item doesn't really matter.

Anyway, Im not in toolset now so I can't really make the function for you and im too lazy to compile it from snippet above in textpad, maybe later if noone else does. But yes for the spellshool you only need single 2DAlookup with only one required parameter -> spellId. The spell level is a bit complicated as it depends on last spell cast class.

// functions for getting spell school and level


int GetSpellLevel(int nSpellID, int nCasterType)
{
int nReturn;
string sType = "Innate";
switch (nCasterType)
   {
   case 1: sType = "Bard"; break;
   case 2: sType = "Cleric"; break;
   case 3: sType = "Druid"; break;
   case 6: sType = "Paladin"; break;
   case 7: sType = "Ranger"; break;
   case 9:
   case 10: sType = "Wiz_Sorc"; break;
   }
nReturn = StringToInt(Get2DAString("spells", sType, nSpellID));
return nReturn;
}

void main()
{
int nSpellID = GetSpellId();

int nSpellLevel = GetSpellLevel(nSpellID, GetLastSpellCastclass());
string sSpellSchool = Get2DAString("spells", "School", nSpellID);
}

For formating any type of text, this forum sucks.  You'll have to manually capitalize the last "c" in GetLastSpellCastclass().

The string sSpellSchool will return a single character representing the spell's school:
A = abjuration
C = conjuration
D = divination
E = enchantment
I = illusion
N = necromancy
T = transmutation
V = evocation

Unfortunately I'm already better than 1/2 through the revisions of my spell system...

I just simply used nwn wiki and looked up each spell to ensure that the proper level & school were checked in the spell vs a private function, that way there is as little lag as possible...

Thanks for the help guys anyway.
