For SE_Gate, base2 is which bind to use (starting at 1)
For SE_BindAffinity, base1 is which bind to set (starting at 1)
For SE_GateCastersBindpoint, base1 is which bind to use (starting at 1)
here was actually no spells that don't send to the main bind,
but it uses a base1 of 1 which matches with SE_Gate
This also doesn't break anything
The quest stuff for now hasn't been updated to be able to make use of the extra binds
There are a total of 5 bind points, with the 5th being your starting city
- When a zone boots, it will spawn an invisible npc by the name of zone_controller
- Lua and Perl scripts can be represented with this npc as zone_controller.pl/lua
- This NPC's ID is ruled be define ZONE_CONTROLLER_NPC_ID 10
- Two EVENT's uniquely are handled with this NPC/controller (They only work with the zone_controller NPC)
- EVENT_SPAWN_ZONE :: All NPC spawns in the zone trigger the controller and pass the following variables:
$spawned_entity_id
$spawned_npc_id
- EVENT_DEATH_ZONE :: All NPC deaths in the zone trigger the controller event and pass the following variables:
$killer_id
$killer_damage
$killer_spell
$killer_skill
$killed_npc_id
- NPC:NPCToNPCAggroTimerMin 500 (Now 6000) 6 seconds
- NPC:NPCToNPCAggroTimerMax 2000 (Now 60000) 60 seconds
- Database version 9089 will take care of this update automatically only if you used the default values
- The CPU cost of NPC's checking the entire entity list to cast beneficial spells (Heals/Buffs) becomes extremely high when
higher NPC count zones exist (Based off of process profiling)
- Distance checks for every single NPC to every single other NPC who are casting beneficial spells occur every .5 - 2 seconds unless
npc_spells dictates other values, which most of the time it does not
- Zones that once fluctuated from 1-8% CPU with no activity (Idle but players present) now idle at .5% based on my testings due
to this change in conjunction with the past few performance commits, these are zones that have 600-800 NPC's in them
- These values normally are overidden by the spells table (npc_spells), fields (idle_no_sp_recast_min, idle_no_sp_recast_max)
- Added Rate limit the rate in which signals are processed for NPC's (.5 seconds instead of .01 seconds)
Added Perl Export Settings which should heavily reduce the Perl footprint
- Normally when any sub EVENT_ gets triggered, all kinds of variables have to get exported every single time an event is triggered and
this can make Perl very slow when events are triggered constantly
- The two most taxing variable exports are the item variables ($itemcount{} $hasitem{} $oncursor{}) and qglobals ($qglobals{})
- qglobals can pose to be an issue quickly when global qglobals build up, it is highly recommend to use the GetGlobal() and SetGlobal()
methods instead as they don't reference the hashmap $qglobals{} that is rebuilt every single time a sub event is triggered
- A stress test conducted with 10,000 samples shows an excess of time taken to export variables: http://i.imgur.com/NEpW1tS.png
- After the Perl Export Settings table is implemented, and all exports are shut off you see the following test result:
http://i.imgur.com/Du5hth9.png
- The difference of eliminating uneeded exports brings the overhead and footprint of 10,000 triggers from 54 seconds to 2 seconds
- In a 10,000 sample test (10,000 sub event triggers), exporting item variables adds 12 seconds alone, when item variables are only needed in
EVENT_ITEM and EVENT_SAY a majority of the time if at all
- In a 10,000 sample test (10,000 sub event triggers), exporting qglobals with approximately 1,000 global qglobals in the database creates
about 11-20 seconds of delay on its own (Depending on hardware of course)
- I've written a parser that has determined which of these exports are needed in which sub routines and have turned off all of the unneeded
exports in sub routines that do not need them and used it to create the default table that will be installed in the database.
- The export table is called 'perl_event_export_settings' and it resembles the following structure and contains all current 81 EVENTS
- If an entry doesn't exist in this table and a new subroutine is added to the source, all exports will be on by default for that routine
+----------+-----------------------------------------+-----------------+------------+-------------+-------------+--------------+
| event_id | event_description | export_qglobals | export_mob | export_zone | export_item | export_event |
+----------+-----------------------------------------+-----------------+------------+-------------+-------------+--------------+

- If a change is made to this table while the server is live and running, you can hot reload all zone process settings via:
#reloadperlexportsettings
- For those who wonder what "exports" are, they are reference to variables that are made available at runtime of the sub event, such as:
(export_qglobals) (Heavy) : $qglobals https://github.com/EQEmu/Server/blob/master/zone/embparser.cpp#L916
(export_item) (Heavy) : $itemcount{} $hasitem{} $oncursor{} https://github.com/EQEmu/Server/blob/master/zone/embparser.cpp#L1103
(export_zone) : $zoneid, $instanceid, $zoneln etc. https://github.com/EQEmu/Server/blob/master/zone/embparser.cpp#L1083
(export_mob) : $x, $y, $z, $h, $hpratio etc. https://github.com/EQEmu/Server/blob/master/zone/embparser.cpp#L1032
(export_event) : (event specific) IE: EVENT_SAY ($text) https://github.com/EQEmu/Server/blob/master/zone/embparser.cpp#L1141
Added a custom Health Update message that will display in the middle of the players screen, to enable this server wide you must enable rule 'Character:MarqueeHPUpdates'
(Haynar) Fixed some runspeed issues with Perl and LUA scripts
(Haynar) Updated #showstats and #npcstats for new speed calcs to display speeds again in familiar float format.
(Haynar) Improved client movement while AI Controlled, such as feared and charmed. Movement will be much smoother from clients perspective.
Added parameter to LUA and Perl method settime(hour, minute, [update_world = true])
- If update_world is false, the zone will then unsubscribe itself from regular worldserver time synchronizations
Added DB ver 9082 with update to add npc_types texture columns if table does not currently have them
