=head1 CROSSFIRE+ OBJECT AND INTERNALS DOCUMENTATION |
| 2 |
|
| 3 |
Here is all information about the object types Crossfire+ |
| 4 |
supports at the moment. This is not a complete documentation (yet) |
| 5 |
and browsing the source is still recommended to learn about |
| 6 |
the objects that aren't documented here. |
| 7 |
|
| 8 |
This documentation is in a sketchy state. It's mostly |
| 9 |
used to collect notes about the internal behaviour of the |
| 10 |
objects. |
| 11 |
|
| 12 |
=head2 About archetypes and objects |
| 13 |
|
| 14 |
Field denotes an attribute of an archetype. |
| 15 |
This is an example of an archetype: |
| 16 |
|
| 17 |
Object button_trigger |
| 18 |
name button |
| 19 |
type 30 |
| 20 |
face button_sma.111 |
| 21 |
anim |
| 22 |
button_sma.111 |
| 23 |
button_sma.112 |
| 24 |
mina |
| 25 |
is_animated 0 |
| 26 |
exp 30 |
| 27 |
no_pick 1 |
| 28 |
walk_on 1 |
| 29 |
walk_off 1 |
| 30 |
editable 48 |
| 31 |
visibility 50 |
| 32 |
weight 1 |
| 33 |
end |
| 34 |
|
| 35 |
This archetype has the name 'button_trigger' and the objects that |
| 36 |
inherit from this archetype have the name 'button'. |
| 37 |
|
| 38 |
The next field 'type' decides the main behaviour of this archetype. |
| 39 |
For a comprehensive list of types see include/define.h. For this case |
| 40 |
you might find a line like: |
| 41 |
|
| 42 |
#define TRIGGER_BUTTON 30 |
| 43 |
|
| 44 |
The server internally works with objects that 'inherit' attributes from |
| 45 |
an archetype. They have a similar set of attributes. |
| 46 |
|
| 47 |
The following documentation will also document the meaning of code internal |
| 48 |
attributes of objects. These attributes are marked as '(internal)' and can't |
| 49 |
or shouldn't be set by an archetype. If the internal names differs the |
| 50 |
external name (for the archetypes) for the attribute is written behind it. |
| 51 |
|
| 52 |
=head2 Description of generic archetype and object attributes |
| 53 |
|
| 54 |
These are the fields that most of the objects have and/or their |
| 55 |
default behaviour. |
| 56 |
|
| 57 |
=over 4 |
| 58 |
|
| 59 |
=item name <string> |
| 60 |
|
| 61 |
The name of the object. |
| 62 |
|
| 63 |
=item name_pl <string> |
| 64 |
|
| 65 |
The name of a collection of these objects (the plural of the name). |
| 66 |
|
| 67 |
=item face <facename> |
| 68 |
|
| 69 |
The graphical appearance of this object. |
| 70 |
|
| 71 |
=item invisible <number> |
| 72 |
|
| 73 |
If the <number> is greater than 0 the object is invisible. |
| 74 |
For players this field reflects the duration of the invisibility |
| 75 |
and is decreased every tick by 1. |
| 76 |
|
| 77 |
For non-player objects this field is not changed by server ticks. |
| 78 |
|
| 79 |
=item speed <numeric> |
| 80 |
|
| 81 |
If this field is greater than MIN_ACTIVE_SPEED (~0.0001) the object is placed |
| 82 |
on the active object list and will be processed each tick (see also speed_left!). |
| 83 |
|
| 84 |
If the speed field drops below the MIN_ACTIVE_SPEED the object is removed |
| 85 |
from the active object list and it won't experience any processing per tick. |
| 86 |
|
| 87 |
=item speed_left <number> |
| 88 |
|
| 89 |
If this field is greater than 0 and the object is on the |
| 90 |
active list (mostly means it's speed is also greater than 0): |
| 91 |
|
| 92 |
- speed_left is decreased by 1 |
| 93 |
- and this object is processed and experiences a server tick. |
| 94 |
|
| 95 |
If the object is on the active list and speed_left is lower or |
| 96 |
equal to 0 the absolute value of the speed field is added to speed_left |
| 97 |
on the end of the tick. |
| 98 |
|
| 99 |
=item no_drop (0|1) |
| 100 |
|
| 101 |
Sets the flag FLAG_NO_DROP. See the Flags section below. |
| 102 |
|
| 103 |
=item applied (0|1) |
| 104 |
|
| 105 |
Sets the flag FLAG_APPLIED. See the Flags section below. |
| 106 |
|
| 107 |
=item is_used_up (0|1) |
| 108 |
|
| 109 |
Sets the flag FLAG_IS_USED_UP. See Flags section below. |
| 110 |
|
| 111 |
=item editable (more than deprecated) |
| 112 |
|
| 113 |
This field had a special meaning for crossedit, which used parts |
| 114 |
of the server code for editing. Wherever you see this attribute being |
| 115 |
set in an archetype ignore it and/or remove it. No code interprets this |
| 116 |
field anymore. |

=head3 Flags |
| 121 |
|
| 122 |
Here are the effects of the flags described. |
| 123 |
|
| 124 |
=over 4 |
| 125 |
|
| 126 |
=item FLAG_NO_DROP |
| 127 |
|
| 128 |
An object can't be picked up and dropped. |
| 129 |
|
| 130 |
=item FLAG_APPLIED |
| 131 |
|
| 132 |
This flag mostly states whether this object has been 'applied' by the player. |
| 133 |
For objects that are applied by the code or have this flag set in the archetype |
| 134 |
it mostly means 'this object is active'. |
| 135 |
|
| 136 |
For example the player adjustments of the hp/sp/grace fields and inheritance |
| 137 |
of flags from objects in his inventory is toggled by this flag. |
| 138 |
|
| 139 |
=item FLAG_IS_USED_UP |
| 140 |
|
| 141 |
This flag controls whether an object is 'used up'. If it is set the 'food' field |
| 142 |
of the object is decreased by 1 each tick, and if it is lower or equal 0 after tha |
| 143 |
it is removed. |
| 144 |
|
| 145 |
If also the flag FLAG_APPLIED is set, the 'duration' field controls whether |
| 146 |
this object is removed or not, see the Force type below for the meaning |
| 147 |
of the duration field in this context. |
| 148 |
|
| 149 |

|
| 151 |
=head2 Description of type specific attributes |
| 152 |
|
| 153 |
The beginning of the headers of the following subsection |
| 154 |
are the server internal names for the objects types, see include/define.h. |
| 155 |
The numeric values are maybe not 100% accurate, as the code is a changing |
| 156 |
target, please consult include/define.h in doubt :-) |
| 157 |
|
| 158 |
=head3 WEAPON - type 15 - Weapons |
| 159 |
|
| 160 |
This type is for general hack and slash weapons like swords, maces |
| 161 |
and daggers and and .... |
| 162 |
|
| 163 |
=over 4 |
| 164 |
|
| 165 |
=item weapontype <type id> |
| 166 |
|
| 167 |
decides what attackmessages are generated, see include/define.h |
| 168 |
|
| 169 |
=item attacktype <bitmask> |
| 170 |
|
| 171 |
bitfield which decides the attacktype of the damage, see include/attackinc.h |
| 172 |
|
| 173 |
=item dam <number> |
| 174 |
|
| 175 |
amount of damage being done with the attacktype |
| 176 |
|
| 177 |
=item item_power <level> |
| 178 |
|
| 179 |
the itempower of this weapon. |
| 180 |
|
| 181 |
=item name |
| 182 |
|
| 183 |
the name of the weapon. |
| 184 |
|
| 185 |
=item level (internal) |
| 186 |
|
| 187 |
The improvement state of the weapon. |
| 188 |
If this field is greater than 0 the 'name' field starts with the |
| 189 |
characters name who improved this weapon. |
| 190 |
|
| 191 |
=item last_eat (internal) |
| 192 |
|
| 193 |
seems to be the amount of improvements of a weapon, |
| 194 |
the formular for equipping a weapon seems to be (server/apply.C:check_weapon_power): |
| 195 |
|
| 196 |
((who->level / 5) + 5) >= op->last_eat |
| 197 |
|
| 198 |
=item last_sp |
| 199 |
|
| 200 |
the weapon speed (see magic description) |
| 201 |
|
| 202 |
=item food <number> |
| 203 |
|
| 204 |
addition to food regeneration of the player |
| 205 |
|

|
| 208 |
addition to health regeneration |
| 209 |

| 215 |
|
| 216 |
addititon to grace regeneration |
| 217 |
|
| 218 |
=item gen_sp_armour <number> |
| 219 |
|
| 220 |
the players gen_sp_armour field (which is per default 10) is added the <number> amount. |
| 221 |
gen_sp_armour seems to be a factor with which gen_sp in do_some_living() |
| 222 |
is multiplied: gen_sp *= 10/<number> |
| 223 |
meaning: values > 10 of gen_sp_armour limits the amout of regenerated |
| 224 |
spellpoints. |
| 225 |
|
| 226 |
generally this field on weapons is in ranges of 1-30 and decides the slowdown of the |
| 227 |
sp regeneration. |
| 228 |
|
| 229 |
=item body_<body slot/part> |
| 230 |
|
| 231 |
the part of the body you need to use this weapon, possible values should be |
| 232 |
looked up in common/item.C at body_locations. |
| 233 |
|
| 234 |
=item resist_<resistnacy> <number> |
| 235 |
|
| 236 |
this is the factor with which the difference of the players resistancy and 100% |
| 237 |
is multiplied, something like this: |
| 238 |
|
| 239 |
additional_resistancy = (100 - current_resistanct) * (<number>/100) |
| 240 |
|
| 241 |
if <number> is negative it is added to the total vulnerabilities, |
| 242 |
and later the total resistance is decided by: |
| 243 |
|
| 244 |
'total resistance = total protections - total vulnerabilities' |
| 245 |
|
| 246 |
see also common/living.C:fix_player |
| 247 |
|
| 248 |
=item patch_(attuned|repelled|denied) |
| 249 |
|
| 250 |
this field modifies the pathes the player is attuned to, see include/spells.h PATH_* |
| 251 |
for the pathes. |
| 252 |
|
| 253 |
=item luck <number> |
| 254 |
|
| 255 |
this luck is added to the players luck |
| 256 |
|
| 257 |
=item move_type |
| 258 |
|
| 259 |
if the weapon has a move_type set the player inherits it's move_type |
| 260 |
|
| 261 |
=item exp <number> |
| 262 |
|
| 263 |
the added_speed and bonus_speed of the player is raised by <number>/3. |
| 264 |
if <number> < 0 then the added_speed is decreased by <number> |
| 265 |
|
| 266 |
=item weight |
| 267 |
|
| 268 |
the weight of the weapon |
| 269 |
|
| 270 |
=item magic |
| 271 |
|
| 272 |
the magic field affects the amounts of the following fields: |
| 273 |
|
| 274 |
- wc : the players wc is adjusted by: player->wc -= (wc + magic) |
| 275 |
|
| 276 |
- ac : the players ac is lowered by (ac + magic) if (player->ac + magic) > 0 |
| 277 |
|
| 278 |
- dam: the players dam is adjusted by: player->dam += (dam + magic) |
| 279 |
|
| 280 |
- weapon speed (last_sp): weapon_speed is calculated by: (last_sp * 2 - magic) / 2 |
| 281 |
(minium is 0) |

|
| 300 |
Note: Forces only take effect on the player if they have set FLAG_APPLIED. |
| 301 |
|
| 302 |
Whether the duration field is processed or not a tick is controlled via the |
