After a request made by EthrenDiak, where he wanted an AW set, I decided to do just that.
After "making" an area where I want the items to be found, I put them inside a chest.
But I want this chest to fire off a dialogue.
I can do that easily enough, with an invisible placeable over the chest, and having the chest as inactive.
Now, I want the dialogue to activate the chest again, and then remove or disable the invisible "dialogue-chest"-placeable.

Now, how do I do this? I've tried mixing what little I know of scripting, but it doesn't work. Not so strange, considering I know next to nothing.

I would like this script to use a plot-check, too, which I already use in the dialogue.
Anyone who can help out a poor fellow here?

Why not just use the chest to initiate the conversation and check your plot flags/conversation choices and spawn the item directly in the player's inventory?

Well, I am using the chest, or an invisible one anyway, to initiate the
conversation. But no matter what I do, I can't get it to work. I could
use some help with designing a script that adds the items after the
conversation, and de-activates the conversation-chest, so that it can't
be talked to again.
As it is, I can talk to it, then nothing happens.
I'm using a script, slightly modified to what I thought would
work, which it apparently did not. I could post it, I suppose, to see
if someone could point out what I should do to get it to work. As I
said, I've never really scripted before, so my head is drowning in
stuff it doesn't understand.
-------
#include "utility_h"
#include "plt_motw_box_plot"

void main()
{

if ( WR_GetPlotFlag( PLT_MOTW_BOX_PLOT, BOX_SEAL_GONE_FLAG ) == FALSE )
return;

( WR_GetPlotFlag( PLT_MOTW_BOX_PLOT, BOX_SEAL_GONE_FLAG ) == TRUE )
event ev = GetCurrentEvent();
int nEventType = GetEventType(ev);
switch ( nEventType )
{

case EVENT_TYPE_MODULE_LOAD:
{

UT_AddItemToInventory(R"arm_motw_bot_arc.uti", 1);
UT_AddItemToInventory(R"arm_motv_glv_arc.uti", 1);

WR_SetPlotFlag( PLT_MOTW_BOX_PLOT, BOX_SEAL_GONE_FLAG, FALSE );
break;
}

default:
break;
}
}
------
That's it.
Now, how much of it is utterly wrong? It isn't that much different
from weriKK's script provided in one of his/hers tutorials. Should I
use that, or must I make a new script from the ground? How shall that
script look, then?

So, you have a chest.  When you click it, it should open a dialogue (a conversation)  to remove a seal from the chest. After that the inventory of the chest should open automatically.

Well, I have never tried that. But if you select File->New->Placeable that would allow to define the shape of the placeable and a script that would override the placeable_core script. So, that sould be able to launch a dialogue (a conversation).

In a conversation it's possible to run a specific script whan a proper replay is selected.  In that script you could call OpenInventory() function that should allow you to browse the content of the chest.  But I have never tried OpenInventory() call. This could be good scripting practice so I give it a try and see if it works.

Yes, it seems to work. I used two scripts to do that and I hate that a little. There is a generic plot "gen00pt_generic_actions" that contains many options but unfortunately "UNLOCK_TARGET" isn't one of them. So, that led in a solution of two scripts. I suppose it could be possible to get a rid of the second script if a plot is used somehow.

A Script for the chest:

#include "placeable_h"
void main()
{
    event ev       = GetCurrentEvent();
    int nEventType = GetEventType(ev);
    switch (nEventType)
    {
        //----------------------------------------------------------------------
        // Sent by engine when player clicks on object.
        //----------------------------------------------------------------------
        case EVENT_TYPE_PLACEABLE_ONCLICK:
        {
            BeginConversation(GetHero(), OBJECT_SELF);
            return;
        }
    }
   HandleEvent(ev, RESOURCE_SCRIPT_PLACEABLE_CORE);
}

 

And the second script run from the conversation:

void main()
{
    object oChest = GetObjectByTag("magic_chest");
    SetPlaceableActionResult(oChest, PLACEABLE_ACTION_UNLOCK, TRUE);
    OpenInventory(oChest, GetHero());
}

I'll give it a try. Thanks in advance.

Also, how have you learned so much about scripting? Trial and error?

I haven't exactly looked around, but I don't know what to look for, either.

A few after thoughts.

1. It could be better to use SetPlaceableState instead of SetPlaceableActionResult

2. Container state must be checked before launching a conversation. No point if the container is already open.

3. The second script can be placed in a Plot_Script:

......
if(nType == EVENT_TYPE_SET_PLOT) // actions -> normal flags only
    {
        int nValue = GetEventInteger(eParms, 2);        // On SET call, the value about to be written (on a normal SET that should be '1', and on a 'clear' it should be '0')
        int nOldValue = GetEventInteger(eParms, 3);     // On SET call, the current flag value (can be either 1 or 0 regardless if it's a set or clear event)
        // IMPORTANT: The flag value on a SET event is set only AFTER this script finishes running!
        switch(nFlag)
        {
            case BOX_SEAL_GONE_FLAG:
            {
                if (nValue==1) {
                     object oChest = GetObjectByTag("magic_chest");
                     SetPlaceableState(oChest,PLC_STATE_CONTAINER_STATIC_UNLOCKED);
                     OpenInventory(oChest, GetHero());
                }
            }
        }
     }
.....

Ok, all this sounds intriguing. And would probably work if I only knew how to use it correctly.
The first script isn't that hard to understand. Basically copy/paste into a new script, right?
But the second one is the one I'm having a hard time understanding.
How exactly do I make it work? Put it in a new script, obviously, with the correct starting line (void main()), but then? I take my plot and exchange the script, replacing the old "_core"-script with the new one, right? Is there anything I should change? The tag in the second script I changed, of course. But is there anything else I have to do?

I've given it a try, but it still doesn't work. Now the chest does not fire up a dialogue, and I can't do anything with it. I click on it, and nothing happens. It's as if the script refuses to start. I don't get it. I'm not a scripting kind of guy, so I fail to see what's wrong.

Perhaps I've used the scripts wrong somehow, but if so, you'll probably have to explain it to me, almost step-by-step.
Also, when I compile the second script, it complains about an error of some kind.
"motw_for_boxscript.nss(12): Variable defined without type (while compiling var_constants_h.nss)"
Which points to this part: --> if(nType == EVENT_TYPE_SET_PLOT)


Anyway, I'll try it without the first script, and see if it can do anything without it.
