//sc_givexp_pick: Give XP on Pick Lock by KidCharlemagne 9/15/02

//Script gives experience points to a PC who picks a lock.
//Place this script in the OnUnLock Event of the door, chest, etc.
//They must not have key in inventory for it to work.

//Note: Although I arrived at this idea independently, I later
//found a similar script on NWN Vault to give xp when a trap
//is disarmed.  This script was written by Velmar.  I give credit
//to a like minded individual. :)

//VARIABLES:
//
//nExp = XP to be given
//oPC = PC who unlocked object
//oItem = variable to check through oPC's inventory
//sKey = string of key required to unlock object
//oKey = key object required to unlock object
//nDC = DC to unlock object
//nAlreadyPicked = local integer on calling object to prevent PC
//                 from locking object and picking to gain xp
//                 repeatedly

void main()
{

//VARIABLE DECLARATIONS----------------------------
