Get Value of a Custom Item Property?
« on: July 11, 2016, 06:10:22 pm »


               

After tinkering with CEP I saw a new Item property - Use Limitation: Gender.

It doesn't have or at least I can't find any functionalities implemented, so I started implementing my own. I saw in itempropdef.2da that the ID of the property is 150 and that it is getting its values from gender.2da

The problem is that I can't get what gender is selected (I think it's called subtype?) for it to limit.


 


GetItemPropertyCostTableValue() in the following function always returns 0:



// This scipt is attached on OnPlayerEquipItem

object oItem = GetPCItemLastEquipped();
object oPC   = GetPCItemLastEquippedBy();
itemproperty ipLoop = GetFirstItemProperty(oItem);

while (GetIsItemPropertyValid(ipLoop))
{   
   if  (GetItemPropertyType(ipLoop) == 150 ) // Check to see if the item has UseLimitationGender
      {
         int nCost = GetItemPropertyCostTableValue(ipLoop);
         SendMessageToPC(oPC, IntToString(nCost));
      }

   ipLoop = GetNextItemProperty(oItem);
}

I guess GetItemPropertyCostTableValue() is not the function I have to use?


 


 


Yes, I know all of this can be achieved with a simple variable on the equipment but I want to use the property (it has a text in the game interface).

You want the subtype. i.e. : GetItemPropertySubType(ipLoop).

Ah, sounds so logical. Couldn't find this function in the Lexicon... Thank you, once again!

Oh, and now - a bonus question time!


 


Is there OnEquip for henchmen? Because currently, if I make Female-Only Armor, I can equip it on a male henchman.

No, OnPlayerEquipItem is only for players. You have to prevent the henchman from acquiring the item in OnAcquireItem. This is my custom code for single player:

Sorry that oPC is a confusing variable name, it ought to be oHenchman or whatever, but I don't have time to edit it this morning!

@proleric, does that actually work? I've been under the impression that OnAcquireItem and friends also only fire for PCs.

               Yes, it works. Live code from my Dark Energy module. OnPlayerX events only work for player (the clue is in the name) but OnAcquireItem works for NPCs.

Interesting!


 


Someone should update some of the lexicon pages then.  Grimlar's Tag based scripting tutorial, for example, clearly says no (at least in the CHM version).  Having read that I had not bothered looking at it closely...  Does it fire when stores acquire items or just creature objects? Chests?


 


I like the ghosting visuals hack. I'm going to crib that one for my cursed item stuff which has that issue '<img'>

Well cool.  Seems to fire for all creatures. How about activate? I did not think you could make NPCs activate item special powers.   I guess I need to use a bigger grain of salt when looking at the lexicon '<img'>

               I don't know of a way to force a creature to activate an item (unless there is some backdoor using spell functions). If that's correct, then OnActivateItem is player-only.


You could, of course, by-pass the event, by modding the creature AI to execute a similar script if it has the item in inventory and ought to activate it. I do something like that with thieves' tools, for example.

Aah, this worked! Nice!


 


What is the purpose of the last line (the conversation one)?


 


And what is that ghosting visuals hack that meaglyn talks about?

               The conversation simply displays custom token 12. Sorry, should have explained that. If you prefer floaty text or a message instead, no problem. I prefer conversation because it's more obvious and has to be cleared by the player once read.


Dummy out the OpenInentiory lines to see the ghosting they prevent.
