14	Field denotes an attribute of an archetype.	26	Archetypes are 'templates' of objects. If an object is derived
		27	from an archetype the object fields will be set to the corresponding
		28	fields in the archetype.
		29
		30	When a map is instanciated (loaded), the 'object' description on the
		31	map are considered patches of the archetype.
		32
		33	This document does explain the behaviour of the objects and the meaning of
		34	their fields in the server engine, which are derived from archetypes.

58	=head2 Description of type specific attributes	81	=item I<name> <string>
		82
		83	The name of the object.
		84
		85	=item I<name_pl> <string>
		86
		87	The name of a collection of these objects (the plural of the name).
		88
		89	=item I<face> <facename>
		90
		91	The graphical appearance of this object.
		92
		93	=item I<x> <number>
		94
		95	The x position of the object when it is on a map.
		96
		97	=item I<y> <number>
		98
		99	The y position of the object when it is on a map.
		100
		101	=item I<map> (internal)
		102
		103	The map the object is on.
		104
		105	=item I<invisible> <number>
		106
		107	If the <number> is greater than 0 the object is invisible.
		108	For players this field reflects the duration of the invisibility
		109	and is decreased every tick by 1.
		110
		111	For non-player objects this field is not changed by server ticks.
		112
		113	=item I<glow_radius> <number>
		114
		115	This field indicates how far an object glows. Default is a radius of 0 (no
		116	glowing at all). Negative glow radii darken areas - currently, negative
		117	glow radii are stronger than positive ones.
		118
		119	=item I<speed> <float>
		120
		121	If this field is greater than MIN_ACTIVE_SPEED (~0.0001) the object is placed
		122	on the active object list and will be processed each tick (see also speed_left!).
		123
		124	If I<speed> drops below the MIN_ACTIVE_SPEED the object is removed
		125	from the active object list and it won't experience any processing per tick.
		126
		127	Negative speed settings in archetypes and files cause a speed_left
		128	randomisation on load or instantiatian, but for calculations, the absolute
		129	value is used always.
		130
		131	=item I<speed_left> <float>
		132
		133	If this field is greater than 0 and the object is on the
		134	active list (mostly means it's speed is also greater than 0):
		135
		136	- speed_left is decreased by 1
		137	- and this object is processed and experiences a server tick.
		138
		139	If the object is on the active list and I<speed_left> is lower or
		140	equal to 0 the absolute value of the I<speed> is added to I<speed_left>
		141	on the end of the tick.
		142
		143	This means: the lower I<speed> is (but still above MIN_ACTIVE_SPEED)
		144	the more seldom the object is processed. And the higher I<speed> is
		145	the more often the object is processed.
		146
		147	=item I<connected> <identifier>
		148
		149	When this field is set the object will be linked to a connection with the
		150	same <identifier>. What happens when the connection is 'activated' depends on the
		151	type of the object.
		152
		153	FLAG_ACTIVATE_ON_PUSH and FLAG_ACTIVATE_ON_RELEASE they will control
		154	when to activate the object, see description of these below for further details.
		155

		188	Sets the flag FLAG_REFLECTING.
		189	See Flags section below.

		191	=item I<reflect_spell> (0\|1)
		192
		193	Sets the flag FLAG_REFL_SPELL.
		194	See Flags section below.
		195
		196	=item I<no_skill_ident> (0\|1)
		197
		198	Sets the flag FLAG_NO_SKILL_IDENT.
		199	See Flags section below.

		201	=item I<activate_on_push> (0\|1) (default: 1)
		202
		203	Sets the flag FLAG_ACTIVATE_ON_PUSH.

		210
		211	=item I<is_lightable> (0\|1)
		212
		213	Sets the flag FLAG_IS_LIGHTABLE.
		214	See Flags section below.
		215
		216	=item I<editable> (more than deprecated)
		217
		218	This field had a special meaning for crossedit, which used parts
		219	of the server code for editing. Wherever you see this field being
		220	set in an archetype ignore it and/or remove it. No code interprets this
		221	field anymore.
		222
		223	=back
		224
		225	=head3 Flags
		226
		227	Here are the effects of the flags described.
		228
		229	=over 4
		230
		231	=item FLAG_NO_DROP
		232
		233	An object can't be picked up and dropped.
		234
		235	=item FLAG_APPLIED
		236
		237	This flag mostly states whether this object has been 'applied' by the player.
		238	For objects that are applied by the code or have this flag set in the archetype
		239	it mostly means 'this object is active'.
		240
		241	For example the player adjustments of the I<hp>/I<sp>/I<grace> fields and inheritance
		242	of flags from objects in his inventory is toggled by this flag.
		243
		244	=item FLAG_IS_USED_UP
		245
		246	This flag controls whether an object is 'used up'. If it is set I<food>
		247	is decreased by 1 each tick, and will be removed when I<food> is lower or equal 0.
		248
		249	If also the flag FLAG_APPLIED is set, the I<duration> field controls whether
		250	this object is removed or not, see the B<FORCE> type below for the meaning
		251	of the duration field in this context.
		252
		253	If FLAG_APPLIED is not set the object is destroyed.
		254
		255	=item FLAG_CHANGING
		256
		257	If the I<state> field of the object is 0 the object will be processed periodically
		258	(if I<speed> is set). If the I<state> field is 1 it won't be processed.
		259
		260	This flag indicates that the object is changing into a different object.
		261	The object has to have the I<other_arch> field set. The object the changing object
		262	changes into is derived from the archetype in I<other_arch>.
		263
		264	When the object does not have FLAG_ALIVE set the I<food> field will be decremented
		265	each time the object is processed, and if I<food> reaches 0 one new object will be generated.
		266
		267	When the object has FLAG_ALIVE set the I<food> field is the number of objects that
		268	will be generated.
		269
		270	After the new object is created the I<hp> field from the old object is copied into
		271	the new one.
		272
		273	=item FLAG_IS_A_TEMPLATE (internal use)
		274
		275	This flag is set on the inventory of generators like B<CREATOR>s and B<CONVERTER>s,
		276	or other objects that have the flags FLAG_GENERATOR and FLAG_CONTENT_ON_GEN set.
		277
		278	=item FLAG_AUTO_APPLY
		279
		280	This flag has currently only meaning for the B<TREASURE> type, see below.
		281
		282	=item FLAG_ACTIVATE_ON_PUSH
		283
		284	This flag has only meaning for objects that can be linked together
		285	by the I<connected> field and controls wether the object should
		286	be activated when the connection is 'pushed' or it is 'released'.
		287
		288	What 'pushed' and 'released' means depends on the object that
		289	activates the connection.
		290
		291	This flag is by default on.
		292
		293	=item FLAG_ACTIVATE_ON_RELEASE
		294
		295	This flag has only meaning for objects that can be linked together
		296	by the I<connected> field and controls wether the object should
		297	be activated when the connection is 'pushed' or it is 'released'.
		298
		299	What 'pushed' and 'released' means depends on the object that
		300	activates the connection.
		301
		302	This flag is by default on.
		303
		304	=item FLAG_NO_STEAL
		305
		306	When this flag is set this object can't be stolen. The flag will be
		307	reset once the object is placed on a map.
		308
		309	When this flag is set on a monster it can defend attempts at stealing
		310	(but in this context the flag is only used internally).
		311
		312	=item FLAG_NO_SKILL_IDENT
		313
		314	This flag is mostly used internal and prevents unidentified objects
		315	(objects which don't have FLAG_IDENTIFIED set) being identified
		316	multiple times by skills.
		317
		318	This flag is used to mark objects which were unsuccessfully identified by a
		319	players skill. So that multiple tries of identifying aren't more effective than
		320	one.
		321
		322	=item FLAG_REFLECTING
		323
		324	This flag is used by spell effects (eg. SP_BOLT), B<THROWN_OBJ> and B<ARROW>
		325	to indicate whether this object reflects off walls.
		326
		327	=item FLAG_REFL_SPELL
		328
		329	This flag indicates whether something reflects spells, like spell reflecting
		330	amuletts.
		331
		332	=item FLAG_IS_LIGHTABLE
		333
		334	This flag indicates whether a B<LIGHTER> can light this object. See also the
		335	description of the B<LIGHTER> type. How easy you can light an item depends
		336	partially on the material of the object.
		337
		338	=item FLAG_MONSTER
		339
		340	Enables NPC behaviour in general (both monster AI and friendly AI). Numerous fields
		341	change their meaning, including:
		342
		343	=over 4
		344
		345	=item I<wis>
		346
		347	Governs the "wake-up radius" - the radius within a monster detects an enemy.
		348
		349	Also, I<wis> governs pathfinding intelligence: 8 and up means the monster
		350	will partake in basic smell finding. 10 and up additionally spreads smell
		351	knowledge, and 15 and up additionally will try to perturb the path as to
		352	find shortcuts.

64		362
		363	=head3 B<TRANSPORT> - type 2 - Player transports
		364
		365	This type is implemented by the transport extension and has currently no special
		366	fields that affect it.
		367
		368	=head3 B<ROD>, B<HORN> - type 3, 35 - Rods that fire spells
		369
		370	Rods contain spells and can be fired by a player.
		371
		372	=over 4
		373
		374	=item I<level> <number>
		375
		376	This field is used for calculating the spell level that can be fired
		377	with this rod, it's also the maximum level of the spell that can be fired.
		378	The level of the spell that is being fired depends mostly on
		379	the 'use magic item' skill level of the player and 1/10 of the level of the
		380	rod is added as bonus.
		381
		382	=item I<hp> <number>
		383
		384	The amount of spellpoints this rod has left. Recharges at a rate of C<1 +
		385	maxhp/10> per tick.
		386
		387	=item I<maxhp> <number>
		388
		389	The maximum amount of spellpoints this rod has.
		390
		391	=item I<skill> <skill name>
		392
		393	This field determines which skill you need to apply this object.
		394
		395	=back
		396
		397	=head3 B<TREASURE> - type 4 - Treasures
		398
		399	This type of objects are for random treasure generation in maps.
		400	If this object is applied by a player it will replace itself with it's
		401	inventory. If it is automatically applied
		402	generate a treasure and replace itself with the generated treasure.
		403
		404	Chests are also of this type, their treasures are generated by
		405	the auto apply code on map instantiation.
		406
		407	=over 4
		408
		409	=item I<hp> <number>
		410
		411	The number of treasures to generate.
		412
		413	=item I<exp> <level>
		414
		415	If FLAG_AUTO_APPLY is not set the exp field has no further meaning
		416	and the difficulty for the treasurecode only depends on the maps difficulty,
		417	otherwise the exp field has the following meaning:
		418
		419	If this field is not 0 it is passed as the difficulty
		420	to the treasure generation code to determine how good, how much
		421	worth a treasure is or what bonuses it is given by the treasure code.
		422
		423	If this field is not set or 0 the difficulty of the map is passed to the treasure
		424	generation code.
		425
		426	=item I<randomitems> <treasurelist>
		427
		428	The treasurelist to use to generate the treasure which is put in the
		429	treasure objects inventory.
		430
		431	=back
		432
		433	=head3 B<POTION> - type 5 - Potions for drinking and other nastynesses
		434
		435	These objects contain a spell and will emit it on apply, which most
		436	of the time has the meaning of 'drinking'.
		437
		438	If no resistancy field, stat field or attacktype is set and no spell
		439	is put in the potion by the sp field or the randomitems the
		440	potion will become an artifact and the artifact code decides which kind
		441	of potion will be generated.
		442
		443	If the potion has FLAG_CURSED or FLAG_DAMNED set the usage of this potion
		444	will yield an explosion and hurt the player.
		445
		446	=over 4
		447
		448	=item I<Str>, I<Dex>, I<Con>, I<Int>, I<Wis>, I<Cha>, I<Pow> <number>
		449
		450	These stat fields determine how many stat points the player gets
		451	when he applies this potion.
		452
		453	If FLAG_CURSED or FLAG_DAMNED is set the player will loose that many stat points.
		454
		455	=item I<sp> <number>
		456
		457	If this field is set and the randomitems field is not set
		458	the field is interpreted as spell number, please look the right
		459	number up in common/loader.C.
		460
		461	If this field is set the randomitems field will be unset by the
		462	map loading code.
		463
		464	=item I<attacktype> <attacktype>
		465
		466	This field has some special meaning in potions, currently the
		467	bits for AT_DEPLETE and AT_GODPOWER control whethere this is a
		468	restoration potion or improvement potion.
		469	See include/attackinc.h for the bits of these types.
		470
		471	If AT_DEPLETE is set the player will be restored and the "depletion"
		472	will be removed from him. If the potion has FLAG_CURSED or FLAG_DAMNED
		473	set the player will be drained a random stat by inserting an "depletion"
		474	into him.
		475
		476	If AT_GODPOWER is enabled the player will gain +1 maxvalue in his hp, sp or grace stat.
		477	When the potion has FLAG_CURSED or FLAG_DAMNED set he will loose one in one of these stats.
		478
		479	=item I<resist_RESISTANCY> <number>
		480
		481	If this stat is set and no spell is in the potion the potion
		482	will create a force that give the player this specific resistancy.
		483	The forces type will be changed to POTION_EFFECT (see POTION_EFFECT type below)
		484	and the potion will last 10 times longer than the default force archetype
		485	FORCE_NAME (at the moment of this writing spell/force.arc).
		486
		487	=item I<randomitems> <treasurelist>
		488
		489	The inventory/spell of the potion will be created by calling the treasure code
		490	with the treasurelist specified here. (I guess it's highly undefined what
		491	happens if there is not a spell in the potions inventory).
		492
		493	=item I<on_use_yield> <archetype>
		494
		495	When this object is applied an instance of <archetype> will be created.
		496
		497	=item I<subtypes> <potion subtype>
		498
		499	see include/spells.h for possible potion subtypes, there are currently 4:

		532
		533	The specialty of B<FLESH> is that it inherits the resistancies of the
		534	monsters it was generated in and will let dragons raise their resistancies
		535	with that. If the monster has the B<POISON> attacktype the B<FLESH>
		536	will change into B<POISON>.
		537
		538	If a player runs low on food he will grab for B<FOOD>, B<DRINK> and B<POISON>

		584
		585	This is the amount of damage the player will receive from applying this. The
		586	attacktype AT_POISON will be used to hit the player and the damage will
		587	determine the strenght, duration and depletion of stats of the poisoning. The
		588	created B<POISONING> object which is being placed in the one who was attacked will
		589	get the damage from this field (which is maybe adjusted by slaying or the

		707
		708	=item I<wc> <number>
		709
		710	The weapon class of the arrow, which has effect on the probability of hitting.

		713
		714	wc = 20 - bow->magic - arrow->magic - (skill->level or shooter->level)
		715	- dex_bonus - thaco_bonus - arrow->stats.wc - bow->stats.wc + wc_mod
		716
		717	When the arrow is not being shot by an player dex_bonus and thaco_bonus and the

		745	arrow will be stopped immediatly.
		746
		747	On fireing the I<speed> of the arrow is computed of 1/5 of the
		748	sum of the damage bonus (see BOW), bow I<magic> and arrow I<magic>. After that 1/7

		755	If the I<speed> is above 10.0 it goes straight through the creature it hits and
		756	its I<speed> is reduced by 1. If the I<speed> is lower or equal 10.0 the arrow is
		757	stopped and either stuck into the victim (see I<weight> field description) or

		774	reset for reuse.
		775
		776	=item I<slaying> <string>
		777
		778	When the bow that fires this arrow has it's I<slaying> field set it is copied

		1035
		1036	=head3 B<CHECK_INV> - type 64 - Inventory checkers
		1037
		1038	This object checks whether the player has a specific item in his
		1039	inventory when he moves above the inventory checker. If the player has
		1040	the item (or not, which can be controlled with a flag) a connection will be triggered.
		1041
		1042	If you set I<move_block> you can deny players and monsters to reach the space where
		1043	the inventory checker is on, see I<move_block> description below.
		1044
		1045	The conditions specified by I<hp>, I<slaying> and I<race> are OR concationated.
		1046	So matching one of those conditions is enough.
		1047
		1048	=over 4
		1049
		1050	=item I<move_block> <move type bitmask>
		1051
		1052	If you set this field to block a movetype the move code will block any moves
		1053	onto the space with the inventory checker, IF the moving object doesn't have
		1054	(or has - if I<last_sp> = 0) the item that the checker is searching for.
		1055
		1056	=item I<last_sp> (0\|1)
		1057
		1058	If I<last_sp> is 1 'having' the item that is being checked for will
		1059	activate the connection or make the space with the checker non-blocking.
		1060	If I<last_sp> is 0 'not having' the item will activate the connection
		1061	or make the space with the checker non-blocking.
		1062
		1063	=item I<last_heal> (0\|1)
		1064
		1065	If I<last_heal> is 1 the matching item will be removed if the inventory checker
		1066	activates a connection and finds the item in the inventory.
		1067
		1068	(A inventory checker that blocks a space won't remove anything from inventories)
		1069
		1070	=item I<hp> <number>
		1071
		1072	If this field is not 0 the inventory checker will search for an object
		1073	with the type id <number>.
		1074
		1075	=item I<slaying> <string>
		1076
		1077	If this field is set the inventory checker will search for an object that
		1078	has the same string in the I<slaying> field (for example a key string of a key).
		1079
		1080	=item I<race> <string>
		1081
		1082	If this field is set the inventory checker will search for an object which
		1083	has the archetype name that matches <string>.
		1084
		1085	=item I<connected> <identifier>
		1086
		1087	This is the connection that will be activated. The connection is
		1088	'pushed' when someone enters the space with the inventory checker,
		1089	and it is 'released' when he leaves it.
		1090
		1091	See also the description of the I<connected> field in the generic object
		1092	field section.
		1093

		1101	(based on value that last_sp takes):
		1102	0: 'furious' Makes all monsters aggressive
		1103	1: 'angry' As above but pets are unaffected

		1105	3: 'sleep' Puts all monsters to sleep
		1106	4: 'charm' Makes monster into a pet of person
		1107	who triggers the square. This setting
		1108	is not enabled for continous operation
		1109	5: 'destroy mons' destroy any monsters on this space
		1110	6: 'destroy pets' destroy friendly monsters on this space
		1111

		1117
		1118	A type for any object that has no special behaviour.
		1119
		1120	=head3 B<DUPLICATOR> - type 83 - Duplicators or: Multiplicators
		1121
		1122	This type of objects multiplies objects that are above it when it is activated.
		1123	You can even multiply by 0, which will destroy the object.
		1124
		1125	=over 4
		1126
		1127	=item I<level> <number>
		1128
		1129	The multiplicator, if set to 0 or lower it will destroy the objects above it.
		1130
		1131	=item I<other_arch> <string>
		1132
		1133	The archetype name of the objects that should be multiplied.
		1134
		1135	=item I<connected> <identifier>
		1136
		1137	See generic object field description.
		1138
		1139	=back
		1140
		1141	=head3 B<HOLE> - type 94 - Holes
		1142
		1143	B<HOLE>s are holes in the ground where objects can fall through. When the hole
		1144	opens and/or is completly open all objects above it fall through (more
		1145	precisely: if their head is above the hole).
		1146
		1147	When the B<HOLE> is activated it's speed is set to 0.5.
		1148
		1149	These holes can only transfer the one who falls through to other coordinates
		1150	on the same map.
		1151
		1152	=over 4
		1153
		1154	=item I<maxsp> (0\|1)
		1155
		1156	This field negates the state of the connection: When maxsp is 1 the pit will
		1157	open/close when the connection is deactivated. Otherwise it will open/close
		1158	when the connection is activated. This field only has effect when the
		1159	connection is triggered. So if you put a closed hole on a map, and the
		1160	connection is deactivated, and I<maxsp> is 1 the hole will remain closed until the
		1161	connection was triggered once.
		1162
		1163	=item I<connected> <identifier>
		1164
		1165	This is the connection id, which lets the hole opening or closing when
		1166	activated. The flags FLAG_ACTIVATE_ON_PUSH and FLAG_ACTIVATE_ON_RELEASE control
		1167	at which connection state the object is activated.
		1168
		1169	For example: if FLAG_ACTIVATE_ON_RELEASE is set to 0 the hole won't react when
		1170	the connection is released.
		1171
		1172	=item I<wc> <number> (internal)
		1173
		1174	This is an internal field. If it is greater than 0 it means that the hole is not
		1175	yet fully open. More preciesly: this field is the animation-step and if it is
		1176	set to the 'closed' step of the animation the hole is closed and if it is on
		1177	the 'open' animation step (I<wc> = 0), the hole is open.
		1178
		1179	=item I<sp> <number>
		1180
		1181	The destination y coordinates on the same map.
		1182
		1183	=item I<hp> <number>
		1184
		1185	The destination x coordinates on the same map.
		1186
		1187	=back
		1188
		1189	=head3 B<POISONING> - type 105 - The poisoning of players and monsters
		1190
		1191	This type is doing the actual damage to the ones who were attacked
		1192	via AT_POISON (or drank B<POISON>).
		1193
		1194	The duration is handled via the FLAG_IS_USED_UP mechanism (please look
		1195	there for details).
		1196
		1197	=over 4
		1198
		1199	=item I<dam> <number>
		1200
		1201	Each time the poisoning is proccessed (which is determined by the I<speed> and
		1202	I<speed_left> fields, see the general object fields description above) it hits
		1203	the player with <number> damage and the AT_INTERNAL attacktype (means: it will
		1204	simply hit the player with no strings attached).
		1205
		1206	=item I<food> <number>
		1207
		1208	Just a note: The posioning is removed if I<food> == 1 and not if
		1209	the whole I<duration> is up, because the B<POISONING> code has to remove
		1210	the poison-effects from the player before the FLAG_IS_USED_UP mechanism
		1211	deletes the B<POISONING> object.
		1212
		1213	=back
		1214
		1215	=head3 B<FORCE> - type 114 - Forces
		1216
		1217	Forces are a very 'thin' type. They don't have much behaviour other than
		1218	disappearing after a time and/or affecting the player if they are in his
		1219	inventory.
		1220
		1221	Forces only take effect on the player if they have FLAG_APPLIED set.
		1222
		1223	Whether the I<duration> field is processed or not per tick is controlled by the
		1224	I<speed> and I<speed_left> fields. Look above in the generic object field description.
		1225
		1226	NOTE: If FLAG_IS_USED_UP is set on a B<FORCE> it's I<food> field will also
		1227	interpreter like described in the description of the FLAG_IS_USED_UP flag.
		1228	BUT: If I<food> reaches 0 before I<duration> and FLAG_APPLIED is set, the force
		1229	will still last for I<duration>. If the FLAG_APPLIED is not set the force is
		1230	removed when I<food> reaches 0. Generally this means: FLAG_IS_USED_UP doesn't
		1231	have good semantics on forces, try to avoid it.
		1232
		1233	=over 4
		1234
		1235	=item I<duration>
		1236
		1237	While this field is greater than 0 the force/object is not destroyed. It is
		1238	decreased each tick by 1.
		1239
		1240	If it reaches 0 the force/object is destroyed.
		1241
		1242	This field can have this meaning for B<any> object if that object has
		1243	FLAG_IS_USED_UP and FLAG_APPLIED set. See the description of FLAG_IS_USED_UP
		1244	what happens then.
		1245
		1246	=back
		1247
		1248	=head3 B<POTION_EFFECT> - type 115 - Potion effects (resistancies)
		1249
		1250	This object is generated by the B<POTION> code when the potion is a resistance
		1251	giving potion. It has mainly the same behaviour as a B<FORCE>.
		1252
		1253	The specialty of the potion effect is that the resistancy it gives is absolute,
		1254	so if you drink a resistancy potion of fire+60 you will get 60% absolute resistancy to
		1255	fire.
		1256
		1257	Multiple potion effects only give you the maximum of their resistancy.
