Script for a Buff bot

[Sylaei]

I copied the translocator script from Trev and modified it to allow a player to request a buff, then pay/donate for the buff, then get the buff.

There are probably a lot of scripts in the forums that do this type of stuff, but I like this way, because you can change 3 lines and it will work for about any type of caster bot.

I use 3 arrays for the buffs, one is the name of the buff, one is the cost of the buff, and one is the spell id to cast. I also use a qglobal variable for the npc to remember the spell to cast.

The beauty of scripting like this is that once this is working for a few spells it will be easily modifiable for any other buff bot type npc.

My idea is to have an npc for each class that can provide buffs or ports. I then want them to randomly appear and after a while to leave. This is a step in the direction of imitating live with players that would buff for donations.

One final note: I am not really a perl programmer, like I said I just copied Trev's code and modified it some. If there is a way to make this better or a more proper way, please let me know.

#A buff bot script.
#Buffs a player for pp.

#SpellList is the array containing the names of the spells. SpellCost is the amount in pp for each spell. SpellID is the spell that is cast by the npc.
#Note these are 3 arrays.  Each position in the array corosponds to the same position in the other arrays.
#So I have this set so that if you say 'Spirit of Wolf' and pay 2 pp, then the npc will cast spell 278 on you.
#I am setting the amounts to pp just because they can be any amount you wish, this requires changing the EVENT_ITEM function to handle the other money types.
