14	Field denotes an attribute of an archetype.	26	Archetypes are 'templates' of objects. If an object is derived

		524
		525	The main difference between B<FOOD>, B<FLESH> and B<DRINK> is that they

		527
		528	The specialty of B<FLESH> is that it inherits the resistancies of the
		529	monsters it was generated in and will let dragons raise their resistancies
		530	with that. If the monster has the B<POISON> attacktype the B<FLESH>
		531	will change into B<POISON>.
		532
		533	If a player runs low on food he will grab for B<FOOD>, B<DRINK> and B<POISON>

		579
		580	This is the amount of damage the player will receive from applying this. The
		581	attacktype AT_POISON will be used to hit the player and the damage will
		582	determine the strenght, duration and depletion of stats of the poisoning. The
		583	created B<POISONING> object which is being placed in the one who was attacked will
		584	get the damage from this field (which is maybe adjusted by slaying or the

		704
		705	The weapon class of the arrow, which has effect on the propability of hitting.
		706

		709	wc = 20 - bow->magic - arrow->magic - (skill->level or shooter->level)
		710	- dex_bonus - thaco_bonus - arrow->stats.wc - bow->stats.wc + wc_mod
		711
		712	When the arrow is not being shot by an player dex_bonus and thaco_bonus and the

		736	=item I<speed> <number> (internal)
		737
		738	This field shouldn't be set directly in the archetype, the arrow will get it's
		739	I<speed> from the bow. This fields value has to be at least 0.5 or otherwise the
		740	arrow will be stopped immediatly.
		741
		742	On fireing the I<speed> of the arrow is computed of 1/5 of the
		743	sum of the damage bonus (see BOW), bow I<magic> and arrow I<magic>. After that 1/7

		749
		750	If the I<speed> is above 10.0 it goes straight through the creature it hits and
		751	it's I<speed> is reduced by 1. If the I<speed> is lower or equal 10.0 the arrow is
		752	stopped and either sticked into the victim (see I<weight> field description) or

		769	reset for reuse.
		770
		771	=item I<slaying> <string>
		772
		773	When the bow that fires this arrow has it's I<slaying> field set it is copied

		1069
		1070	This object represents a lamp, that can be carried and switched
		1071	on and off and has a certain amount of fuel in it.
		1072
		1073	A lamp consists of two archetypes: the 'on' archetype and the 'off' archetype.
		1074	Each of them should point at the other one with it's I<other_arch> field.
		1075
		1076	See the I<other_arch> field for the behaviour of a lamp object when it is applied.
		1077
		1078	If this object has FLAG_IS_LIGHTABLE set the lamp can be turned on and off
		1079	with a B<LIGHTER>, see also the description of FLAG_IS_LIGHTABLE.

		1086	generic object flags description.
		1087
		1088	=item I<speed> <number>
		1089
		1090	If FLAG_CHANGING is set the I<speed> field will indicate how fast the
		1091	lamp burns it's fuel (I<food>).
		1092
		1093	Setting FLAG_CHANGING makes only sense on the archetype which represents
		1094	the 'on' state of the lamp.
		1095
		1096	See also the description of FLAG_CHANGING.
		1097
		1098	Lamps which have no FLAG_CHANGING set would also make sense and represent
		1099	lamps that never burn up.
		1100
		1101	=item I<other_arch> <number>
		1102
		1103	This is the field that points to the 'other' archetype which represents the
		1104	opposite state of the lamp. The newly from I<other_arch> derived object will
		1105	replace the current object and will get the value of I<food> of the replaced object.
		1106
		1107	Rationale:
		1108
		1109	When the lamp (on) is applied a new object is derived from the archetype
		1110	in I<other_arch> and the I<food> value is copied to it ('the fuel is
		1111	transferred'). The new lamp (off) object has to have a I<other_arch> field
		1112	which points to the archetype from which a lamp (on) can be derived.
		1113
		1114	=item I<food> <number>
		1115

		1126

		1132
		1133	The archetype name of the objects that should be multiplied.

		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> <connection id>
		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

		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).

		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.

		1217	Forces are a very 'thin' type. They don't have much behaviour other than

		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

		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.
