/**
|
75 |
|
|
* Main part of the ALCHEMY code. From this we call fctns |
76 |
|
|
* that take a look at the contents of the 'cauldron' and, using these ingredients, |
77 |
|
|
* we construct an integer formula value which is referenced (randomly) against a |
78 |
|
|
* formula list (the formula list chosen is based on the # contents of the cauldron). |
79 |
|
|
* |
80 |
|
|
* If we get a match between the recipe indicated in cauldron contents and a |
81 |
|
|
* randomly chosen one, an item is created and experience awarded. Otherwise |
82 |
|
|
* various failure effects are possible (getting worse and worse w/ # cauldron |
83 |
|
|
* ingredients). Note that the 'item' to be made can be *anything* listed on |
84 |
|
|
* the artifacts list in lib/artifacts which has a recipe listed in lib/formulae. |
85 |
|
|
* |
86 |
|
|
* To those wondering why I am using the funky formula index method: |
87 |
|
|
* 1) I want to match recipe to ingredients regardless of ordering. |
88 |
|
|
* 2) I want a fast search for the 'right' recipe. |
89 |
|
|
* |
90 |
|
|
* Note: it is just possible that a totally different combination of |
91 |
|
|
* ingredients will result in a match with a given recipe. This is not a bug! |
92 |
|
|
* There is no good reason (in my mind) why alchemical processes have to be |
93 |
|
|
* unique -- such a 'feature' is one reason why players might want to experiment |
94 |
|
|
* around. :) |
