Raw Blame History

Database script processing
==========================
In addition to *EventAI*, *mangos* provides script processing for various
types of game content. These scripts can be executed when creatures move or die,
when events are executed, and game object spawns/templates are used, on gossip
menu selections, when starting and completing quests, and when casting spells.
Database structure
------------------
All script tables share a common structure, to store parameterized commands for
the various types of game content.
`id` column
-----------
* `dbscripts_on_creature_death`: Creature entry
* `dbscripts_on_creature_movement`: DB project self defined id
* `dbscripts_on_event`: Event id. Several sources: spell effect 61, taxi/transport nodes, game object_template data
* `dbscripts_on_go_use`: Game object guid
* `dbscripts_on_go_template_use`: Game object entry
* `dbscripts_on_gossip`: DB project self defined id
* `dbscripts_on_quest_end`: DB project self defined id (generally quest entry)
* `dbscripts_on_quest_start`: DB project self defined id (generally quest entry)
* `dbscripts_on_spell`: Spell id
`delay` column
--------------
Delay in seconds. Defines the order in which steps are executed.
`command` column
----------------
The action to execute.
`datalong` columns
------------------
2 multipurpose fields, storing raw data as unsigned integer values.
`buddy_entry` column
--------------------
1 field to store the entry of a "buddy". Depending on the command used this can
can point to a game object template or and creature template entry.
`search_radius` column
----------------------
Range in which the buddy defined in `buddy_entry` will be searched. In case of
`SCRIPT_FLAG_BUDDY_BY_GUID` this field is the buddy's guid!
`data_flags` column
-------------------
Field which holds a combination of these flags:
Value | Name | Notes
----- | ------------------------------- | ------------------------------------
1 | SCRIPT_FLAG_BUDDY_AS_TARGET |
2 | SCRIPT_FLAG_REVERSE_DIRECTION |
4 | SCRIPT_FLAG_SOURCE_TARGETS_SELF |
8 | SCRIPT_FLAG_COMMAND_ADDITIONAL | (Only for some commands possible)
16 | SCRIPT_FLAG_BUDDY_BY_GUID | (Interpret search_radius as buddy's guid)
32 | SCRIPT_FLAG_BUDDY_IS_PET | (Do not search for an NPC, but for a pet)
`dataint` columns
-----------------
4 multipurpose fields, storing raw data as signed integer values.
*Note*: used for text ids SCRIPT_COMMAND_TALK (0),
for emote ids in SCRIPT_COMMAND_EMOTE (1),
for spell ids in SCRIPT_COMMAND_CAST_SPELL (15)
and as waittime with SCRIPT_COMMAND_TERMINATE_SCRIPT (31)
`x`, `y`, `z` and `o` columns
-----------------------------
Map coordinates for commands that require coordinates
Origin of script and source/target in scripts
---------------------------------------------
* `dbscripts_on_creature_death`: Creature death.
Source: creature. Target: Unit (player/creature)
* `dbscripts_on_creature_movement`: `creature_movement` and `creature_movement_template`.
Source: creature. Target: creature
* `dbscripts_on_event`: Flight path with source: player and target: player,
transport path with source: transport game object and target transport game
object, `gameobject_template` with source: user (player/creature) and target:
game object, spells having effect 61 with source: caster and target: target.
* `dbscripts_on_go_use`, `dbscripts_on_go_template_use`: game object use with
source: user: and target: game object.
* `dbscripts_on_gossip`: `gossip_menu_option`, `gossip_menu` with source: creature
and target: player in case of NPC-Gossip, or with source: player and target:
game object in case of GO-Gossip.
* `dbscripts_on_quest_end`: `quest_template` with source: quest taker (creature/GO)
and target: player.
* `dbscripts_on_quest_start`: `quest_template` with source: quest giver (creature/GO)
and target: player.
* `dbscripts_on_spell`: spell with effect 77(SCRIPT_EFFECT), spells with effect 3
(DUMMY), spells with effect 64 (TRIGGER_SPELL, with non-existing triggered spell)
having source: caster: and target: target of spell (Unit).
Buddy concept
-------------
Commands except the ones requiring a player (like KILL_CREDIT) have support
for the buddy concept. This means that if an entry for `buddy_entry` is
provided, aside from source and target as listed above also a "buddy" is
available.
Which one on the three (`originalSource`, `originalTarget`, `buddy`) will
be used in the command, depends on the `data_flags` settings.
Note that some commands (like EMOTE) use only the resulting source for an
action.
Possible combinations of the flags:
* `SCRIPT_FLAG_BUDDY_AS_TARGET`: 0x01
* `SCRIPT_FLAG_REVERSE_DIRECTION`: 0x02
* `SCRIPT_FLAG_SOURCE_TARGETS_SELF`: 0x04
are
* 0: originalSource / buddyIfProvided -> originalTarget
* 1: originalSource -> buddy
* 2: originalTarget -> originalSource / buddyIfProvided
* 3: buddy -> originalSource
* 4: originalSource / buddyIfProvided -> originalSource / buddyIfProvided
* 5: originalSource -> originalSource
* 6: originalTarget -> originalTarget
* 7: buddy -> buddy
where `A -> B` means that the command is executed from A with B as target.

TemporaryFactionFlags
---------------------
* `TEMPFACTION_NONE`: 0x00, when no flag is used in temporary faction change, faction will be persistent. It will then require manual change back to default/another faction when changed once
* `TEMPFACTION_RESTORE_RESPAWN`: 0x01, default faction will be restored at respawn
* `TEMPFACTION_RESTORE_COMBAT_STOP`: 0x02, ... at CombatStop() (happens at creature death, at evade or custom script among others)
* `TEMPFACTION_RESTORE_REACH_HOME`: 0x04, ... at reaching home in home movement (evade), if not already done at CombatStop()
The next flags allow to remove unit_flags combined with a faction change (also these flags will be reapplied when the faction is changed back)
* `TEMPFACTION_TOGGLE_NON_ATTACKABLE`: 0x08, remove UNIT_FLAG_NON_ATTACKABLE(0x02) when faction is changed (reapply when temp-faction is removed)
* `TEMPFACTION_TOGGLE_OOC_NOT_ATTACK`: 0x10, remove UNIT_FLAG_OOC_NOT_ATTACKABLE(0x100) when faction is changed (reapply when temp-faction is removed)
* `TEMPFACTION_TOGGLE_PASSIVE` : 0x20, remove UNIT_FLAG_PASSIVE(0x200)
* `TEMPFACTION_TOGGLE_PACIFIED` : 0x40, remove UNIT_FLAG_PACIFIED(0x20000) when faction is changed (reapply when temp-faction is removed)
* `TEMPFACTION_TOGGLE_NOT_SELECTABLE`: 0x80, remove UNIT_FLAG_NOT_SELECTABLE(0x2000000) when faction is changed (reapply when temp-faction is removed)
