        A weak wall is a breakable spot amidst a solid wall. Typically these
        weak walls look similar to their solid "relatives" except for a
        small crack or little chunks of wall on the ground.

Type defined by:

Attributes

Attribute	Field	Description
armor class	living::ac	Weak walls of high <armor class> are less likely to get hit. <armor class> can be considered the "counter piece" to <weapon class>.
artifact	object::artifact	If defined, refers to an artifact to get values from.
block view	FLAG_BLOCKSVIEW	If an item is set to block view, players (and monsters) cannot see beyond it unless they cross it or manage to stand on top.
blocks prayers	blocks_prayer	Similar to damned, but does not appear in detect curse.
changing	FLAG_CHANGING	A <changing> object converts to <food> <other_arch> objects; when it's animation is done. For non-living objects <food> is checked: if it is zero, the change happens; otherwise <food> is decreased by one. I suggest you don't mess with this value - leave the default in place.
client-sided randomized animation?	FLAG_CLIENT_ANIM_RANDOM	If defined, then the object's animation is client-sided. Similar objects are animated independently.
client-sided synchronized animation?	FLAG_CLIENT_ANIM_SYNC	If defined, then the object's animation is client-sided. Similar objects are animated synchronized.
elevation	elevation	The elevation (height above sea level) of this square. It is used for weather calculations and should be in the range -32000..32000. The elevation of a tile must be set in the bottom-most game object; elevation values for non-bottom-most game objects are ignored by the Crossfire server.
glow radius	object::glow_radius	If <glow radius> is set to a value greater zero, the object appears lit up on dark maps. <glow radius> can be a value between 0 and 4, the higher, the more light does the object emit.
health points	living::hp	The <health points> of a weak wall define how long it takes to tear it down. With every successful hit from an opponent, <health points> get drained.
identified	FLAG_IDENTIFIED	If an item is identified, the player has full knowledge about it.
identified animation	identified_animation	If defined, then the object will take this animation when identified.
identified animation speed	identified_anim_speed	If defined, then the object will have this animation speed when identified.
identified image	identified_face	If defined, then the object will take this appareance when identified.
identified random animation?	identified_anim_random	If defined, then the object's animation is in a random sequence when identified.
identified_name	identified_name	If defined, then the object will take this name when identified.
identified_name_pl	identified_name_pl	If defined, then the object will take this plural name when identified.
image	object::face	The image-name defines what image is displayed for this object in-game.
invisible	object::invisible	Generally makes the object invisible. Depending on the object-type, some can be made visible by the show_invisible spell. If in doubt, test it. Putting an invisible object under the floor always prevents it from being shown.
is buildable	FLAG_IS_BUILDABLE	If set, usually for floors, players can use tools and building materials to build above this object.
is used up	FLAG_IS_USED_UP	If set, decrement the <food> field at <speed>. When <food> reaches zero, remove the object.
level	object::level	The <level> of a weak wall works similar to monster levels. Due to the fact that weak walls cannot attack, the level is much less important though.
material	object::material	This bitmask-value informs the player of which material(s) the object consists. Material does also affect how likely the object can be destroyed by hazardous spell-effects.
max health	living::maxhp	<max health> is the maximum amount of <health points> this weak wall can have. Since walls generally don't heal, I doubt this has much real effect.
name	object::name	This is the name of the object, displayed to the player.
no damage	FLAG_NO_DAMAGE	If set to non-zero, the wall cannot be destroyed by attacking it.
non-pickable	FLAG_NO_PICK	If set, the object cannot be picked up (Neither by players nor monsters).
number	object::nrof	This value determines the number of objects in one stack (for example: 100 gold coins => "number = 100"). You should set this at least to one, for any pickable object - otherwise it won't be mergeable into a stack.
plural name	object::name_pl	This is the plural name of the object. A plural name must be set for all items that can be picked up and collected by the player.
price adjustment	price_adjustment	If set, this is the buy and sell price adjustment ratio for the item.
price adjustment for buying	price_adjustment_buy	If set, this is the adjustment ratio when buying the item. Ignored if <price> adjustment is set.
price adjustment for selling	price_adjustment_sell	If set, this is the adjustment ratio when selling the item. Ignored if <price> adjustment is set.
race	object::race	For weak walls, <race> should always be set to "wall", unless you create something fancy like a building which is in fact meant to be a huge animal. Note that shovels slay walls, so they do triple damage against weak walls.

smooth level	object::smoothlevel	If <smooth level> is set to a value greater zero, the object will be drawn partially over adjacent squares having a lower <smooth level> value. The value must be between 0 and 255 (inclusive); 0 means "never overlap adjacent squares".
splitting	FLAG_SPLITTING	A <splitting> object converts to <food> <other_arch> objects; when it is hit physically. For non-living objects <food> is checked: if it is zero, the change happens; otherwise <food> is decreased by one. I suggest you don't mess with this value - leave the default in place.
title	object::title	This is the object's title. Once an object is identified the title is attached to the name. Typical titles are "of Mostrai", "of xray vision" etc.
unpaid	FLAG_UNPAID	An <unpaid> item cannot be used unless a player carried it over a shop mat, paying the demanded price. Setting this flag makes sense only for pickable items inside shops.
value	object::value	Adds a certain value to the object: It will be worth that many times the default value from it's archetype (E.g. "value = 3" means three times worth the default value). Value for buying/selling will be further modified by various factors. Hence, testing values in-game is usually inevitable.
weight	object::weight	This value defines the object's weight in grams (1000g is 1kg). Objects with zero weight are not pickable for players. Still, set the "non-pickable"-flag for explicitly non-pickable objects (hey, this is open source... you never know ;) ).
