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)
