Hi guys,

 

I just started learning how to script and I'm trying to create one where the owner of the chest/door/locket/etc. will run to the player and start a conversation with him/her if him/her open the flagged chest/door/locket/etc.

 

This work just fine:

//Put this script OnOpen
void main()
{


object oPC = GetLastOpenedBy();


if (!GetIsPC(oPC)) return;


SetLocalInt(oPC, "tenta", 1);


object oTarget;
oTarget = GetObjectByTag("c_elf");


AssignCommand(oTarget, ActionStartConversation(oPC, "peguei"));


}

All good, but this means that the owner will run to the player even if he/she is not seeing the PC stealing. I tried something with GetLastPerceived(), but even if the script works and compiles (I know this because the dialog is set to the localInt "tenta" 1 as intended), the owner never runs to the player and starts the dialog.

 

How can I write this so the owner of the chest/door/locket/etc. will only run if he/she sees the PC trying to steal his/her stuff? Thanks!

Can GetObjectSeen be used? The PC should only get away with it if they are not currently visible to the owner.

That project had the wrong game set. I fixed it here:

As a simple solution, you could just run an opposed spot/hide check at the moment that the chest is opened.

Spot checks should have a distance modifier, so it may not be so simple to compute.

I tried the prr-3-nwn2 but as soon the toolset import the erf I get a lot of compile erros: http://postimg.org/image/d4czfzz25/

I never used GetObjectSeen, and I don't know how to insert it on my script. Can you help on that rjshae?

The x0_i0_position include file contains a function called IsDirectionWithinTolerance() that can be used to check whether one creature is facing another within a specified viewing angle.

I'm not sure what's wrong there. Maybe just run a Compile All and see what happens?

just like so

    object oPC = GetLastOpenedBy();
    if (!GetIsPC(oPC)) return;

    SetLocalInt(oPC, "tenta", 1);

    object oTarget = GetObjectByTag("c_elf");

    if (GetObjectSeen(oPC, oTarget))
        AssignCommand(oTarget, ActionStartConversation(oPC, "peguei"));
}

[Dann-J]

GetObjectSeen() should return TRUE If you are within the creature's perception range, and there is nothing blocking line of sight between you and them. I don't know what happens if the creature has been disabled in some way (blinded, stunned, asleep). Those sorts of effects may clear out a creature's visibility list, but unless the creature is hostile then it's unlikely that you can inflict such effects on them yourself (except via script from a conversation node).

 

If you enter stealth mode before coming into their perception range, and they don't spot you, then you should remain unseen as far as that function is concerned.

 

There is also the GetObjectHeard() function, that can be used to see if a creature has at least heard the thief (even if they haven't been seen).

 

Building in a check to see if the creature is currently within the area of effect of a Darkness spell would give tieflings an advantage.

Selecting the routine in the Script Assist should present a message showing the variables.

void main()

    if (!GetIsPC(oPC)) return;

    SetLocalInt(oPC, "tenta", 1);

    object oTarget = GetObjectByTag("c_elf");

    if (GetObjectSeen(oPC, oTarget))
        AssignCommand(oTarget, ActionStartConversation(oPC, "peguei"));
}

 

Hi KevL,

 

Your script worked just fine. I tried, then, to elaborate it a little bit, giving my NPC an ambient script so he will walk around. If the player is patience enough, he/she can wait until the NPC moves to another room and then open the chest. But your script isn't firing even if the NPC is walking around the PC. I'm using this script OnSpawn of the creature:

 

#include "NW_O2_CONINCLUDE"
#include "NW_I0_GENERIC"

void main()
{

     //SetSpawnInCondition(NW_FLAG_SPECIAL_CONVERSATION);

                // upon Perceiving the player. Attach the [NW_D2_GenCheck.nss] script to the desired
                // greeting in order to designate it. As the creature is actually saying this to
                // himself, don't attach any player responses to the greeting.

                // If the NPC has stealth and they are a rogue go into stealth mode
     //SetSpawnInCondition(NW_FLAG_SEARCH);
                // If the NPC has Search go into Search Mode
     //SetSpawnInCondition(NW_FLAG_SET_WARNINGS);
                // This will set the NPC to give a warning to non-enemies before attacking

                               // 2. If the tag of the Way Point is "POST_" + NPC TAG the creature will return this way point after
                               //    combat.
    GenerateNPCTreasure();     //* Use this to create a small amount of treasure on the creature
}

I can't figure out why your script isn't firing if I give this OnSpawn script to my NPC. It works without it =/

[kevL]

it's probably the WalkWayPoints() ...

lets add, ClearActions to the GetObjectSeen() scope, and add some debug:

// ...

SendMessageToPC(GetFirstPC(FALSE), "run PCSeen");
if (GetObjectSeen(oPC, oTarget))
{
    SendMessageToPC(GetFirstPC(FALSE), "PC is Seen");

    AssignCommand(oTarget, ClearAllActions());
    AssignCommand(oTarget, ActionStartConversation(oPC, "peguei"));
}

Goddamn, wish i had known that. When i was creating sneak attack for spells i was using vectors to determine whether the caster could be seen by the target.  Took me ages to figure out the code for that.

Hey KevL,

 

Again you solved the problem, thanks. I just give it an observation to reset the NPC dialog if oPC is not seen and now it is working like I wanted. In the end I got this:

 

void main()
{
    object oPC = GetLastOpenedBy();
   
    if (!GetIsPC(oPC)) return;
     SetLocalInt(oPC, "tenta", 1);

    object oTarget = GetObjectByTag("c_elf");

    if (!GetObjectSeen(oPC, oTarget))
     SetLocalInt(oPC, "tenta", 0);

       else 

         AssignCommand(oTarget, ClearAllActions());
         AssignCommand(oTarget, ActionStartConversation(oPC, "peguei"));

}

The way it is set, the NPC will always talk to you if you keep opening the chest in front of him/her. Is there a way to prevent this script from firing again after the NPC saw you messing with his goods (after all, he/she is already angry with you)?

[kevL]

heya, good to hear. but I want to point out a quirk of your syntax -- in the script above, the conversation will start even if oPC is not seen. It breaks down like so

if (!GetObjectSeen(oPC, oTarget))
{
    SetLocalInt(oPC, "tenta", 0);
}
else
{
    AssignCommand(oTarget, ClearAllActions());
}

AssignCommand(oTarget, ActionStartConversation(oPC, "peguei"));

( spaces and indents don't matter in NwScript, as they do in some other languages ) So the last AssignCommand should be grouped/ scoped within the else{}

if (!GetObjectSeen(oPC, oTarget))
{
    SetLocalInt(oPC, "tenta", 0);
}
else
{
    AssignCommand(oTarget, ClearAllActions());
    AssignCommand(oTarget, ActionStartConversation(oPC, "peguei"));
}

part2: all you need do is set a 'done' condition as a local variable on the chest:

void main()
{
    object oPC = GetLastOpenedBy();

    if (!GetIsPC(oPC)) return;
    if (GetLocalInt(OBJECT_SELF, "bDone") == TRUE) return; // here

    SetLocalInt(oPC, "tenta", 1);

    object oTarget = GetObjectByTag("c_elf");

    if (!GetObjectSeen(oPC, oTarget))
    {
        SetLocalInt(oPC, "tenta", 0);
    }
    else
    {
        SetLocalInt(OBJECT_SELF, "bDone", TRUE); // and here

        AssignCommand(oTarget, ClearAllActions());
        AssignCommand(oTarget, ActionStartConversation(oPC, "peguei"));
    }
}

[Nasher_AOB]

You know, that is really strange. I can guarantee to you that the script is working as intended without those brackets: the NPC only runs towards the PC and talks if he/she sees the PC. But of course I'll do it the right way.

 

Anyway, I'll try your "done" condition and see the results. Thanks for now!

[kevL]

the reason it works the wrong way is because the original 'bug' is helping things along

[Nasher_AOB]

You see, things aren't so alien for me now. It's pure logic when you look to this script "tree" and understand the way its read by the game.

 

This script is complete now. Thank you very much for everything!

[kevL]

ok
