|
|
* Main part of the ALCHEMY code. From this we call fctns |
800 |
|
|
* that take a look at the contents of the 'cauldron' and, using these ingredients, |
801 |
|
|
* we construct an integer formula value which is referenced (randomly) against a |
802 |
|
|
* formula list (the formula list chosen is based on the # contents of the cauldron). |
803 |
|
|
* |
804 |
|
|
* If we get a match between the recipe indicated in cauldron contents and a |
805 |
|
|
* randomly chosen one, an item is created and experience awarded. Otherwise |
806 |
|
|
* various failure effects are possible (getting worse and worse w/ # cauldron |
807 |
|
|
* ingredients). Note that the 'item' to be made can be *anything* listed on |
808 |
|
|
* the artifacts list in lib/artifacts which has a recipe listed in lib/formulae. |
809 |
|
|
* |
810 |
|
|
* To those wondering why I am using the funky formula index method: |
811 |
|
|
* 1) I want to match recipe to ingredients regardless of ordering. |
812 |
|
|
* 2) I want a fast search for the 'right' recipe. |
813 |

* |
814 |
root |
1.43 |
* Note: it is just possible that a totally different combination of |
815 |
|
|
* ingredients will result in a match with a given recipe. This is not a bug! |
816 |
|
|
* There is no good reason (in my mind) why alchemical processes have to be |
817 |
|
|
* unique -- such a 'feature' is one reason why players might want to experiment |
818 |
|
|
* around. :) |
