Item Scripting/Spawn Summon?

Zephirius

I have a little amulet that is supposed to summon a wraith to fight at your side. Only problem is that after I summon him, he's not associated to my group. How do I make him a true summon with it's picture hanging out in the upper right hand corner of my screen?
Also, I'm wholly uncertain on how to spawn the wraith where I click at on the screen? I just spawns next to the PC, PC = lLoc...
Anyway hope your all having a great day, and any help, even a nudge in the proper direction would be awsome.

Little bit of code I have...

object oUsed = GetItemActivated();

  // The following section is for the Amulet of the Dead
  // The amulet summons a wraith.
  if (GetTag(oUsed) == "AMULET_DEAD")
  {
    // Get the PC, first.
    object oPC = GetItemActivator();

    location lLoc = GetLocation(oPC);

    effect eSummon = EffectVisualEffect(VFX_FNF_SUMMON_UNDEAD);
    ApplyEffectAtLocation(DURATION_TYPE_INSTANT, eSummon, lLoc);
    DelayCommand(0.5, CreateObjectVoid(OBJECT_TYPE_CREATURE, "wraith", lLoc));

 //object oMaster = GetMaster(GetObjectByTag("WRAITH"));



  }
}

what script set is your summon using?
I did this with a rod that summons a Golem for wizard's to use as body guards.

I simply use the special ability on the rod to spawn it like you did, but the Golem is using the hechman script set (found on the characters listed in the "Standard/Other" list).

Zephirius

So if I load up the henchman Ai's it will serve as a true summon?

ForSerious

// Create a Summon Creature effect.  The creature is created and placed into the
// caller's party/faction.
// - sCreatureResref: Identifies the creature to be summoned
// - nVisualEffectId: VFX_*
// - fDelaySeconds: There can be delay between the visual effect being played, and the
//   creature being added to the area
// - nUseAppearAnimation: should this creature play it's "appear" animation when it is
//   summoned. If zero, it will just fade in somewhere near the target.  If the value is 1
//   it will use the appear animation, and if it's 2 it will use appear2 (which doesn't exist for most creatures)
effect EffectSummonCreature(string sCreatureResref, int nVisualEffectId=VFX_NONE, float fDelaySeconds=0.0f, int nUseAppearAnimation=0)

Can be used like in the below code. You just have to define nDuration and use the above code to make eSummon.

ApplyEffectAtLocation(DURATION_TYPE_TEMPORARY, eSummon, GetSpellTargetLocation(), HoursToSeconds(nDuration));

Zephirius

Thanks for the heads up ForSerious. It was GetSpellTargetLocation() that I needed to use.

Zephirius

Hmmm... not sure what's wrong, but nothing happens.

object oUsed = GetItemActivated();

  // The following section is for the Amulet of the Dead
  // The amulet summons a wraith.
  if (GetTag(oUsed) == "AMULET_DEAD")
  {
    // Get the PC, first.
    object oPC = GetItemActivator();

    effect eSummon = EffectSummonCreature("wraith", VFX_FNF_SUMMON_UNDEAD, 0.5, 0);

    ApplyEffectAtLocation(DURATION_TYPE_INSTANT, eSummon, GetSpellTargetLocation(), HoursToSeconds(10));

ForSerious

DURATION_TYPE_INSTANT should probably be DURATION_TYPE_TEMPORARY.

Zephirius

Still nothing. Double checked the resref and the tag of the amulet. That's not it.
Darn!

ForSerious

ResRef of the wraith?

Zephirius

Yeah

Zephirius

I've tried the resrefs of several critters just to be sure, but still no summon.

Quilistan

void main()
{
    // Declare major variables
    object oMaster = GetItemActivator();
    // Replace "CREATURERESREF" with the sCreatureResref of whichever monster you wish to summon.
    // Note that sCreatureResref is *not* the same as it's Tag.
    //  You can also replace the _3 with 1-3 for different summon effects.
    effect eSummon = EffectSummonCreature ("grelen_golem", VFX_FNF_SUMMON_MONSTER_3 );
    // Apply the VFX impact and summon effect
    // Adjust the TurnsToSections(10) to reflect how long you want it to last.
    // You can use HoursToSeconds(), RoundsToSeconds() or TurnsToSeconds().
    ApplyEffectToObject (DURATION_TYPE_TEMPORARY, eSummon, oMaster, TurnsToSeconds(20));
}

that is the code for my item, then I have the ai from the henchmen characters running on the summoned golem.

Of course I never know if I do it the best way, but it does work.....

My Summon is a custom creature

My onSpawn script is different also (just noticed), honestly can't remember why. Here is it though.

Humm, it worked first try for me.
So, I have the OnActivate setup to just redirect:

// Simple on activate redirect.
void main()
{
    object oItem = GetItemActivated();
    object oPC = GetItemActivator();
    if(GetIsObjectValid(oItem))
    {
        //SendMessageToPC(GetFirstPC(), GetTag(oItem));
        ExecuteScript(GetTag(oItem), oPC);
    }
}

Then I tried this code:

void main()
{
    object oTarget = GetSpellTargetObject();
    if(GetIsObjectValid(oTarget))
    {
        SendMessageToPC(OBJECT_SELF, "Cannot target there.");
        return;
    }
    location lLoc = GetSpellTargetLocation();
    effect eSummon = EffectSummonCreature("wraith001", VFX_FNF_SUMMON_UNDEAD, 0.5);
    ApplyEffectAtLocation(DURATION_TYPE_TEMPORARY, eSummon, lLoc, HoursToSeconds(10));
}

(I made wraith001 in the pallet beforehand, but tried wraith as well. It summoned a dwarf...)
It made a Wraith, but it had no AI. So you'll have to figure out how to add that to it. I'm sure you can just copy the script set from a standard summon creature resref.

Quilistan

oh like like the tag base active item script.... always forget you can do that to cut down on number of scripts.

Zephirius

Yeah, I can't even get it to spawn

Zephirius

If I use CreateObject I can get a spawn, but I'm not getting anything with EffectSummonCreature()?

ForSerious

Maybe try our scripts in a new module. It's probably something small you're missing.

Zephirius

Thanks guys. I'll try your suggestions...

Zephirius

I'm at a total loss. Tried it in a new module. That didn't work. I'm using unique power, not unique power (self only) so I can target the effect. Gotta be something small like Serious said, but I can't figure it out for the life of me...

Zephirius

Yeah, what's up with the Dwarf? Some 2DA woes?

ForSerious

The dwarf also appears if I leave the ResRef blank (""). So, he must be some creature with no resref in my module.
Even though copying a standard pallet creature like wraith creates a new creature with a resref of wraith001, the actual bluprint resref of the original is nw_wraith. Maybe that's what you're missing... Though you'd still need to make a custom creature so that it would have the right AI.

Zephirius

The only thing I can think of is GetItemActivator(); How it's being used or lack thereof.

// General Initialization:  Find what item was used
     object oUsed = GetItemActivated();

   
     if (GetTag(oUsed) == "AMULET_DEAD")
     {
     // Get the PC, first.
     object oPC = GetItemActivator();



    location lLoc = GetSpellTargetLocation();
    effect eSummon = EffectSummonCreature("allip002", VFX_FNF_SUMMON_UNDEAD, 0.5, 0);
    ApplyEffectAtLocation(DURATION_TYPE_TEMPORARY, eSummon, lLoc, TurnsToSeconds(60));
    }

How do I plug oPC into the the remaining script so that oPC is recongnized as GetItemActivator();

oPC is only being called once to identify as GetItemActivator(); Does oPC need to be referenced at any other time in the remaining script?

ForSerious

Looks like you can't have them both with this approach.
You are correct about GetItemActivator().
You define oPC but never use it.
In order to use it, you have to change ApplyEffectAtLocation to ApplyEffectToObject and put oPC in as the target object. This removes the ability to target where the summon appears.
To keep that, you need to go the ExecuteScript route. Pretty easy:

// General Initialization:  Find what item was used
     object oUsed = GetItemActivated();

   
     if (GetTag(oUsed) == "AMULET_DEAD")
     {
     // Get the PC, first.
     object oPC = GetItemActivator();
     ExecuteScript("summon_script", oPC);
    }

'summon_script' can be what I put earlier, I should just mention that the if(GetIsObjectValid(oTarget)) statement is there to block the user from targeting objects. That way they can only target locations on the ground. You can remove that, of course.

Zephirius

Using ApplyEffectToObject(); Works. But you can't target a location. Mabey that's were the fault lies, is the location? Perhaps that's messign with the spawn... I don't know...

Quilistan

I remember the dwarf thing from way way back early 2000's things defaulted there for some reason.
