Script not working

TheTinman · October 2023

This script compiles fine but does not work. Intended to destroy all enemies when the PC exits an area.

void main()

{

object oPC = GetExitingObject();

object oCreature;

oCreature = GetNearestObject(OBJECT_TYPE_CREATURE);

while(GetIsObjectValid(oCreature))

{

if (GetIsEnemy(oPC, oCreature))

{

DestroyObject(oCreature);

}

oCreature = GetNextObjectInArea();

}

}

The problem is GetNearestObject.

Always ask - what object is running this script?

In this case, it's the area.

So OBJECT_SELF - the default second parameter - is the area.

Since the area has no location, GetNearestObject will return OBJECT_INVALID.

If you specify oPC as the second parameter, it will work, but then you have to change GetNextObjectInArea to GetNearestObject, passing a parameter to get the 2nd, 3rd... instance until there are no more.

Alternatively, start with GetFirstObjectInArea. Test that the object is a creature before testing GetIsEnemy (for good order). Then GetNextObjectInArea is the correct way to continue the lóop.

Ok. I switched lines 9 and 23 to GetFirstObjectInArea and GetNextObjectInArea and it destroyed all the objects in the area. I understand why it did. How do I write the script to check that the objects to sort through are only hostile creatures?

I just got it working. With Prolerics explanation and a look through the nwnlexicon.

void main()

{

object oArea = OBJECT_SELF;

object oPC = GetExitingObject();

object oCreature;

oCreature =  GetFirstObjectInArea(oArea, OBJECT_TYPE_CREATURE);

while(GetIsObjectValid(oCreature))

{

if (GetIsEnemy(oPC, oCreature))

{

DestroyObject(oCreature);

}

oCreature = GetNextObjectInArea(oArea, OBJECT_TYPE_CREATURE);

}

}

The lexicon is hard for me to understand at times. lol!

I'd be surprised if that compiles. GetFirst/NextObjectInArea doesn't take a second parameter.

Try removing OBJECT_TYPE_CREATURE from both, then change the test to

if (GetObjectType(oCreature) == OBJECT_TYPE_CREATURE)
  if (GetIsEnemy(oPC, oCreature))
    {
      DestroyObject(oCreature);
    }

or if you prefer

if ((GetObjectType(oCreature) == OBJECT_TYPE_CREATURE)
&& GetIsEnemy(oPC, oCreature))
    {
      DestroyObject(oCreature);
    }

I tested it just before I posted. It ran fine. Destroyed all hostile creatures and left all non hostile untouched.

The second parameter is new in EE.

That's useful to know, thanks.
