Altar Trigger


Altar_triggers work pretty much like normal altars (drop sacrifice -> connection activated), except for the fact that they reset after usage. Hence, altar_triggers can be used infinitely.

Type defined by:

  • object::type = 31


Attribute Field Description
accept alive things accept_alive If set, this altar will accept living things as sacrifice. Else they will be ignored.
artifact obj::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.
blocked movement obj::move_block If set, the object cannot be passed by players nor monsters.
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.
connection connection value If a connection value is set, the altar will trigger all objects with the same value, when activated. This will only work once.
drop amount liv::food

The drop amount specifies the amount of items (specified in <match item name>) that must be dropped to activate the altar.

If <match item name> is set to "money", then the value of the sacrificed money must be equal to <drop amount> (ie, if food=200, then 200 silver, 20 gold, or 4 platinum will all work.)

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 obj::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.
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.
ignore reset obj::last_sp

If this attribute is enabled, the altar_trigger won't push the connected value by altar reset. Only ONCE by dropping the sacrifice. This is typically used when the altar is connected to a creator, e.g. for selling tickets.

If this attribute is disabled (default), the altar_trigger will push the connected value TWICE per sacrifice: First by dropping sacrifice, second by reset. This mode is typically used for altars being connected to gates, resulting in the gate being opened and closed again.

image obj::face The image-name defines what image is displayed for this object in-game.
invisible obj::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 used up FLAG_IS_USED_UP If set, decrement the <food> field at <speed>. When <food> reaches zero, remove the object.
match item name obj::slaying This string specifies the item that must be put on the altar to activate it. It can either be the name of an archetype, or directly the name of an object. Yet, titles are not recognized by altars. Remember to put a note somewhere, telling the player what he is expected to drop on the altar. (Often this is put in the altar's name: E.g. "drop 100 platinum coins")
material obj::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.
message obj::msg This text will be displayed to the player in the exact moment when the altar is activated.
name obj::name This is the name of the object, displayed to the player.
non-pickable FLAG_NO_PICK If set, the object cannot be picked up (Neither by players nor monsters).
number obj::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 obj::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.
reset time liv::exp Being activated, the altar will reset after <reset time> ticks. After reset, the altar is ready to be activated once again. The default <reset time> is 30.
smooth level obj::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 obj::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 obj::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 obj::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 ;) ).
