25 /* This file contains various #defines that select various options.
26 * Some may not be desirable, and some just may not work.
27 *
28 * There are some options that are not selectable in this file which
29 * may not always be undesirable. An example would be certain
30 * treasures that you may not want to have available. To remove the
31 * activation code would make these items worthless - instead remove
32 * these from the treasure file. Some things to look for are:
33 *
34 * prepare_weapon, improve_*: Allow characters to enchant their own
35 * weapons
36 * ench_armour: Allow characters to enchant their armor.
37 *
38 * In theory, most of the values here should just be defaults, and
39 * everything here should just be selectable by different run time
40 * flags However, for some things, that would just be too messy.

43 /* There are 4 main sections to this file-
44 * Section 1 is feature selection (enabling/disabling certain features)
45 *
46 * Section 2 is compiler/machine dependant section (stuff that just
47 * makes the program compile and run properly, but don't change the
48 * behavior)
49 *
50 * Section 3 is location of certain files and other defaults. Things in
51 * this section generally do not need to be changed, and generally do
52 * not alter the play as perceived by players. However, you may
53 * have your own values you want to set here.

55 * Section 4 deals with save file related options.

59 * SECTION 1 - FEATURES
60 *
61 * You don't have to change anything here to get a working program, but
62 * you may want to on personal preferance. Items are arranged
63 * alphabetically.
64 *
65 * Short list of features, and what to search for:
66 * DEBUG - more verbose message logging?
67 * MAP_CLIENT_X, MAP_CLIENT_Y - determines max size client map will receive
68 * MAX_TIME - how long an internal tick is in microseconds
69 * MANY_CORES - generate core dumps on gross errors instead of continuing?
70 * PARTY_KILL_LOG - stores party kill information

74 /* Use a very easy, non-challenging server?
75 * Defining the COZY_SERVER will make the server much less challenging:
76 * no stats loss on death, much less experience loss.
77 */
78 #define COZY_SERVER 1
79
80 /* Use balanced stat loss code?
81 * This code is a little more merciful with repeated stat loss at lower
82 * levels. Basically, the more stats you have lost, the less likely that
83 * you will lose more. Additionally, lower level characters are shown
84 * a lot more mercy (there are caps on how much of a stat you can lose too).
85 * On the nasty side, if you are higher level, you can lose mutiple stats
86 * _at_once_ and are shown less mercy when you die. But when you're higher
87 * level, it is much easier to buy back your stats with potions.
88 * Turn this on if you want death-based stat loss to be more merciful
89 * at low levels and more cruel at high levels.
90 * Only works when stats are depleted rather than lost. This option has
91 * no effect if you are using genuine stat loss.
92 *
93 * The BALSL_.. values control this behaviour.
94 * BALSL_NUMBER_LOSSES_RATIO determines the number of stats to lose.
95 * the character level is divided by that value, and that is how many
96 * stats are lost.
97 *
98 * BALSL_MAX_LOSS_RATIO puts the upper limit on depletion of a stat -
99 * basically, level/max_loss_ratio is the most a stat can be depleted.
100 *
101 * BALSL_LOSS_CHANCE_RATIO controls how likely it is a stat is depleted.
102 * The chance not to lose a stat is
103 * depleteness^2 / (depletedness^2+ level/ratio).
104 * ie, if the stats current depleted value is 2 and the character is level
105 * 15, the chance not to lose the stat is 4/(4+3) or 4/7. The higher the
106 * level, the more likely it is a stat can get really depleted, but
107 * this gets more offset as the stat gets more depleted.

169 * need to spend to figure this out in addition to bandwidth needs.
170 * The server cpu time should be pretty trivial.
171 * There may be reasons to keep it smaller for the 'classic' crossfire

174 * more.

228 * 10 to the permanent value).

230 * A few thoughts on these default value (by MSW)
231 * gain ratio is pretty much meaningless until exp has been lost, as until
232 * that poin, the value in the settings file will be used.
233 * It is also impossible for the exp to actually be reduced to the permanent
234 * exp ratio - since the loss ratio is .5, it will just get closer and
235 * closer. However, after about half a dozen hits, pretty much all the
