Notes

Xerves here again. A little fix here if you want to change this so potions are only useable by the owner. A few lines of code here only.

mud/world/defines.py

Find the following

RPG_ITEM_TRIGGER_WORN = 0 #chance per tick for just being worn, check is every 30 seconds
RPG_ITEM_TRIGGER_MELEE = 1 #chance of proc on melee strike
RPG_ITEM_TRIGGER_DAMAGED = 2 #chace of proc when user is damaged
RPG_ITEM_TRIGGER_USE = 3 #when used (possibly limited by charges)
RPG_ITEM_TRIGGER_POISON = 4 #applied poison

After it add

RPG_ITEM_TRIGGER_QUAFF = 5 #Same as Use, but forces target as self

mud/worlddocs/itempages.py

Find the following

        RPG_ITEM_TRIGGER_WORN: 'Worn',
        RPG_ITEM_TRIGGER_MELEE: 'Melee',
        RPG_ITEM_TRIGGER_DAMAGED: 'Damaged',
        RPG_ITEM_TRIGGER_USE: 'Use',
        RPG_ITEM_TRIGGER_POISON: 'Poison'

Change it to the following

        RPG_ITEM_TRIGGER_WORN: 'Worn',
        RPG_ITEM_TRIGGER_MELEE: 'Melee',
        RPG_ITEM_TRIGGER_DAMAGED: 'Damaged',
        RPG_ITEM_TRIGGER_USE: 'Use',
        RPG_ITEM_TRIGGER_POISON: 'Poison',
        RPG_ITEM_TRIGGER_QUAFF: 'Quaff'

mud/world/item.py

Find the following

                elif ispell.trigger == RPG_ITEM_TRIGGER_USE

Change it to this

                elif ispell.trigger == RPG_ITEM_TRIGGER_USE or ispell.trigger == RPG_ITEM_TRIGGER_QUAFF:

A few lines down find the following

                    self.doItemSpellUse(mob,ispell.spellProto)

Change it to

                    self.doItemSpellUse(mob,ispell)

A few lines up find the following function and part of its code

    def doItemSpellUse(self,mob,proto):
        tgt = mob.target
        if proto.target == RPG_TARGET_SELF:
            tgt = mob
        if proto.target == RPG_TARGET_PARTY:
            tgt = mob
        if proto.target == RPG_TARGET_ALLIANCE:
            tgt = mob
        if proto.target == RPG_TARGET_PET:
            tgt = mob.pet
        
        if not tgt:
            return

Replace the following code up to the if not tgt: line with this

    def doItemSpellUse(self,mob,spell):
        proto = spell.spellProto
        if spell.trigger == RPG_ITEM_TRIGGER_QUAFF:
            tgt = mob
        else:
           tgt = mob.target
           if proto.target == RPG_TARGET_SELF:
               tgt = mob
           if proto.target == RPG_TARGET_PARTY:
               tgt = mob
           if proto.target == RPG_TARGET_ALLIANCE:
              tgt = mob
           if proto.target == RPG_TARGET_PET:
               tgt = mob.pet
        
        if not tgt:
            return

Example potion

I created a spell potion item file and used a small function to create the potions for me. Here is an example:

from genesis.dbdict import DBItemProto,DBSpellProto,DBEffectProto
from mud.world.defines import *

def CreateSpellPotion(name,spell,level,desc):    
    item = DBItemProto(name = name)
    item.addSpell(spell,RPG_ITEM_TRIGGER_QUAFF,1)
    item.level = level
    item.bitmap = "STUFF/13"
        
    item.useMax = 1
    item.desc = desc
    item.stackMax = 20
    item.stackDefault = 1
    
desc = "This potion restores a small amount of health."
CreateSpellPotion("Potion of Cure Light","Cure Light",1,desc)

This will create a spell potion linking it to an already existing spell. You will need to come up with the bitmap file there (you can change it to 1 if you like). Once this is done compile and when you go to use the potion it won't require a target and automatically target the user.
