Very simple scalable array + hash based quest template
I've been working on this quest for a few days now and I thought I would share the completed product. I really wanted to make a quest template with the following attributes:
- Very easy to modify
- Very easy to scale up to dozens+ of items
- Heavy use of variables to eliminate redundancy, especially of item IDs
- Say links + item links + direct whispering, because those rock!
I knew from previous programming experience that multi dimensional arrays (or I guess perl calls them hashes) holding all the relevant bits of information would be the way to go, but it took some playing to get the syntax and loops just right since I am really only fluent in PHP.
Anyway, below is my completed quest using this method. As this particular quest was intended to give my family and friends a way to start off with some decent equipment, I took some inspiration from current events ... hopefully no one finds the slight US political nod offensive; it's all in good fun! ;)
Lastly, please note that a previous version of this was causing Plane of Knowledge to crash on startup simply by existing in the poknowledge quest folder. I would have to remove it, let the zone start, then put it back and run #reloadqst to get things working. I have not yet reset my server since my final revision, but if anyone has any thoughts on why a quest .pl file would crash a zone bootup I would love to hear them! I am actually suspecting it might be more due to the NPC itself, so deleting him and starting over is on my list of things to try.
The Quest:
Code:
#
# Simple & Scalable
# Array + hash based quest template
#
# Valdaun 10/23/2009
#
################################################
# All turnins follow simple method:
#
# Quest Item + Component Cost = Reward
#
# Extremely scalable from a handful of sets
# to dozens, without any code bloat.
#
# All item IDs are typed only one time,
# reducing errors and simplifying changes
#
# Heavy use on say and item links + npc whispers
# for minimal say spam and ease of npc interaction
