/* the ordering of this is actually doesn't make a difference |
32 |
* However, for ease of use, new entries should go at the end |
33 |
* so those people that debug the code that get used to something |
34 |
* being in the location 4 don't get confused. |
35 |
* |
36 |
* The ordering in save_name, use_name, nonuse_name. |
37 |
* save_name is the name used to load/save it from files. It should |
38 |
* match that of the doc/Developers/objects. The only |
39 |
* real limitation is that it shouldn't have spaces or other characters |
40 |
* that may mess up the match code. It must also start with body_ |
41 |
* use_name is how we describe the location if we can use it. |
42 |
* nonuse_name is how we describe it if we can't use it. I think |
43 |
* the values below will make it pretty clear how those work out |
44 |
* They are basically there to make life a little easier - if a character |
45 |
* examines an item and it says it goes on 'your arm', its pretty clear |
46 |
* they can use it. See the last sample (commented out) for a dragon |
47 |
* Note that using the term 'human' may not be very accurate, humanoid |
48 |
* may be better. |
49 |
* Basically, for the use/nonuse, the code does something like: |
50 |
* "This item goes %s\n", with the use/nonuse values filling in the %s |
