 Back in NWN 1, we could add a property called Unique OnUse or OnUse Self, then write a script that fired when the item was used.

I've searched high and low, but cannot find any property, setting, check box, or drop menu that has this option for items.

What am I missing? I noticed that online modules have items that fire custom scripts when used, so I know it's possible.

In the item editor, you want to pick an 'activated ability'. It is right near the top. This selects an ability from the ABI_base 2DA with abilitytype 4 (which is item abilities). You can add a new item ability (look into 2DA editing on the wiki) and set the spellscript column to the script you would like to run. This script will get called multiple times with different events when the ability is used. Take a look at some of the other ability spellscripts (for example, item_singletarget.nss) for an example of how the system works.

Hmm. Should be able to create a generic entry that just fires off a script with the same tag as the item then, similar to NWN 1

If you set the item's Activated Ability to ITEM_ABILITY_UNIQUE_POWER_SINGLE_USE or ...UNLIMITED_USE, you can intercept usage in the module event script. For example

[dascript]
case EVENT_TYPE_UNIQUE_POWER:
{
int nAbility = GetEventInteger(ev, 0);
object oItem = GetEventObject(ev, 0);
object oCaster = GetEventObject(ev, 1);
object oTarget = GetEventObject(ev, 2);
string sItem = GetTag(oItem);

if (sItem == "cocim_test") zTest();

if (sItem == "cocpt_cod_bks_khasi") zTeleportHeartOfDarkness();
}
[/dascript]

Here I am using tag-based scripting to call a function for each item. It would be a trivial change to call a script with the same name as the item tag.

Well, at the top it just has appearance, basics etc. Only thing in that category I can see is "Item Property Activation Preference" and my only choices are Active When Equipped, Active When Equipped or in Repository, and Active Only In repository.

That doesn't sound like Object Inspector for a Dragon Age item! The first field on that screen is Activated Ability.

@Gisle Aune - I think the OP was about items, not placeables?

OK, then I must have misunderstood...

You know what, I'm a moron, I clicked on the wrong forum section. I needed to post this in NWN 2 Scripting, Not Dragon Age scripting. Gaff.
