Spawning multiple NPCs in one module

[Miltiades]

I want to spawn multiple NPCs in one module. I learned how to spawn a NPC in a module using this tutorial: http://www.lucasforums.com/showthread.php?t=143536

 

I can't make multiple scripts, because the name of the file will always be the same (for example: k_231area_enter.nss => can't make another script with the same name).

 

So I think I have to add a few things to the script. But I don't know anything about scripting. Can someone help?

 

This is the script:

 

void main()

{

object oEntering = GetEnteringObject();

object oPC=GetFirstPC();

if (GetIsPC(oEntering))

{

//check if the object is already there to avoid multiple objects

if (!GetIsObjectValid(GetObjectByTag("o")))

{

//Note that the script uses OBJECT_TYPE_CREATURE instead of OBJECT_TYPE_PLACEABLE - that's the only difference with the container:

CreateObject(OBJECT_TYPE_CREATURE, "my_npc_templateresref", Location(Vector(43.41,-0.28,9.66), 0.0));

 

// this portion is optional and will only work if you spawn the npc not too far from where you enter the area - careful if there are scripted cutscenes too.

// You can also use the On perception event instead of the on enter script for this.

NoClicksFor(0.5);

//Make the NPC walk towards you:

AssignCommand((GetObjectByTag("my_npc_tag")),ActionMoveToObject(oPC));

//Make the npc initiate the converstation after approcahing you:

AssignCommand ((GetObjectByTag("my_npc_tag")), ActionDoCommand(ActionStartConversation(oPC)));

}

 

ExecuteScript("old_a_306onenter", OBJECT_SELF);

}

 

}

void main()   {

object oEntering = GetEnteringObject();
if(GetIsPC(oEntering))
                     {
                      object oNPC1 = GetObjectByTag("MyNPC");
                      if (!GetIsObjectValid(oNPC1))   {
                                                      CreateObject(OBJECT_TYPE_CREATURE, "templateresref", Location(Vector(x, y, z), 0.0));
                                                     }
                      object oNPC2 = GetObjectByTag("MyOtherNPC");
                      if (!GetIsObjectValid(oNPC2))   {
                                                      CreateObject(OBJECT_TYPE_CREATURE, "templateresref", Location(Vector(x, y, z), 0.0));
                                                     }

ExecuteScript("old_entry", OBJECT_SELF);
}
}

 

You can just continue adding your NPCs as you go. That or you can create a chain of these scripts firing. The first one would have:

 

ExecuteScript("script2", OBJECT_SELF);

at the end. And you could continue this provided your first script has the original name - though it is highly inefficient.

I tried the first code you gave, but it only works partially. I wanted a third NPC to spawn, so I copied this once:

 

object oNPC2 = GetObjectByTag("MyOtherNPC");
                      if (!GetIsObjectValid(oNPC2))   {
                                                      CreateObject(OBJECT_TYPE_CREATURE, "templateresref", Location(Vector(x, y, z), 0.0));
                                                     }

 

and changed NPC2 to NPC3 where that was the case.

 

For the second and third NPC I first used two Sith Soldiers. So the tag is: "SithSoldier" and the templateresref is: "n_sithsoldier".

I tried it, but only one of the two Sith Soldiers spawned (NPC1 spawned, NPC2, which is a Sith Soldier, spawned, but NPC3, which is also a Sith Soldier, didn't spawn).

 

Then I tried to change the tag and templateresref from the Sith Soldier, so I got two different NPCs (example: "sithsoldier1" and "sithsoldier2").

Now only my NPC1 spawns, and the other two don't.

 

What's wrong?

So were would you put these scripts?

[tk102]

It's kind of hard of hard to tell from reading this what all your .utc Tag/TemplateResRef are, but maybe another hypothetical script will help?

 

Let's say you want 1 of soldier "A" and 2 of soldier "B" to spawn when you enter area 231TEL where:

soldierA.utc :

- Tag: soldierAtag

- TemplateResRef: soldierAtemp

soldierB.utc :

- Tag: soldierBtag

- TemplateResRef: soldierBtemp

 

And you rename the original k_231_area_enter.nss to old231_enter.nss.

 

Your new k_231area_enter.nss could appear like this:

void main()
{
 object oEntering = GetEnteringObject();
 object oPC=GetFirstPC();
 object oNPCA;
 object oNPCB1;
 object oNPCB2;

 //use whereami armband to get good location coordinates
 location locSpawn=Location(Vector(43.41,-0.28,9.66), 0.0);

 if (GetIsPC(oEntering))
 {
  //check if the soldier A is already spawned 
  if (!GetIsObjectValid(GetObjectByTag("soldierAtag")))
  {
   oNPCA=CreateObject(OBJECT_TYPE_CREATURE, "soldierAtemp", locSpawn); 

    // since soldier A should spawn with the soldier B, we can assume
    // that they have also not yet been spawned.  Spawn them now.
   oNPCB1=CreateObject(OBJECT_TYPE_CREATURE, "soldierBtemp", locSpawn); 
   oNPCB2=CreateObject(OBJECT_TYPE_CREATURE, "soldierBtemp", locSpawn);  

  // here you can script actions for the soldiers using their 
  // object variables: oNPCA, oNPCB1, oNPCB2
   // example:
   //  AssignCommand(oNPCA,ActionMoveToObject(oPC));
   //  AssignCommand(oNPCB1,ActionMoveToObject(oPC));
   //  AssignCommand(oNPCB2,ActionMoveToObject(oPC));
   //  AssignCommand(oNPCB1,ActionMoveToObject(oPC));
   //  AssignCommand(oNPCA, ActionDoCommand(ActionStartConversation(oPC)));
  }
 }
ExecuteScript("old231_enter", OBJECT_SELF);
}

Hey, thanks tk102, it worked!

[Miltiades]

I don't want to start to many threads, so I'll ask my question here.

 

I want to add a journal entry when I take a datapad of a body.

 

I followed the tutorial on "How to add journal entries", but I can't figure out how to use these scripts.

 

---------

 

Next, I want a new journal entry when I collect 4 datapads. How do I do that?
