Server:Faction
This article will attempt to explain how faction works server-side to assist with understanding the various modifiers applied to characters between the base values and the ones you experience in-game.
In the source code, faction is found in /common/faction.h and /common/faction.cpp.
How Faction Gets Calculated
Faction is ultimately calculated in the FACTION_VALUE CalculateFaction(FactionMods* fm, int32 tmpCharacter_value, bool lua = false); function, where
character_value += base value + class modifier + race modifier + deity modifier
The result of this formula is then returned as a FactionValue.
CalculateFaction is called from /zone/client.cppin the GetFactionLevel function. First, the server queries data about the NPC's Primary Faction from the database and stores it in a variable called tmpFactionValue. It then calculates faction bonuses from Alliance type spells and items and adds those to tmpFactionValue. Finally, CalculateFaction is called and passed the modifiers from the NPC's Primary Faction and the tmpFactionValue.
Faction Properties
The Faction struct defined in /common/faction.h defines the following members:
| Property | Data Type | Description |
|---|---|---|
| id | int32 | database identifier |
| mods | std::map<std::string, int16> | |
| base | int16 | The base, unmodified value that players start with for this faction before race, class, and deity modifiers are applied |
| name | char array 50 | The name of the faction |
| see_illusion | bool | Determines whether the faction will see through racial illusion spells |
| min_cap | int16 | Minimum value players can reach with this faction |
| max_cap | int16 | Maximum value players can reach with this faction |
Faction Modifiers
The FactionMod struct defined in /common/faction.h defines the following members:
- int32 base
- int32 class_mod
- int32 race_mod
- int32 deity_mod
Faction Value Ranges
| Min Cap | Max Cap | FACTION_VALUE (Enum) |
|---|---|---|
| >= 2000 | - | FACTION_MAX_ALLY = 0 |
| >= 1100 | - | FACTION_ALLY = 1 |
| >= 750 | <= 1099 | FACTION_WARMLY = 2 |
| >= 500 | <= 749 | FACTION_KINDLY = 3 |
| >= 100 | <= 499 | FACTION_AMIABLY = 4 |
| >= 0 | <= 99 | FACTION_INDIFFERENTLY = 5 |
| >= -100 | <= -1 | FACTION_APPREHENSIVELY = 6 |
| >= -500 | <= -101 | FACTION_DUBIOUSLY = 7 |
| >= -750 | <= -501 | FACTION_THREATENINGLY = 8 |
| - | <= -751 | FACTION_SCOWLS = 9 |
| - | <= -2000 | FACTION_MAX_SCOWLS = 10 |
The range of faction values above which are returned as the enums described in the final column are filtered through the const char *FactionValueToString(FACTION_VALUE faction_value); function to convert them to the corresponding string equivalent before being sent to the client and used for in-game consider or similar messages.
NPC Faction
The NPCFaction struct defined in /common/faction.h defines the following members:
| Property | Data Type | Description |
|---|---|---|
| factionID | uint32 | |
| value_mod | int32 | |
| npc_value | int8 | |
| temp | uint8 |
