"respects_u" |
integer, the faction's starting opinion of the player. Has no meaningful effect in game and may be removed in the future. |
"trusts_u" |
integer, the faction's starting trust of the player. Determines which item groups are available for trade by NPCs in the faction. Scales similarly to "likes_u" and "respects_u". |

For conditionals, the avatar is used as alpha and the evaluating npc as beta |

Interacting with factions has certain effects on how the faction sees the player. These are reflected in values like likes_u, respects_u and trusts_u. Here's a (non-comprehensive) list to provide some context on how much these values are worth:
| Type of interaction | Effect on likes_u |
Effect on respects_u |
Effect on trusts_u |
|---|---|---|---|
| Neutral state | 0 | 0 | 0 |
| Player is warned by faction | - 1 | - 1 | - 1 |
| Player delivers food supply to faction camp | + food nutritional value / 1250 | + food nutritional value / 625 | + food nutritional value / 625 |
| Player triggers a mutiny | likes_u / 2 + 10 |
- 5 | - 5 |
| Player angers an NPC | - 5 | - 5 | - 5 |
| Player completes a mission | + 10 | + 10 | + 10 |
Factions can have relations with each other that apply to each member of the faction. Faction relationships are not reciprocal: members of the Free Merchants will defend members of the Lobby Beggars, but members of the Lobby Beggars will not defend members of the Free Merchants.
Faction relationships are stored in a dictionary, with the dictionary keys being the name of the faction and the values being a second dictionary of boolean flags. All flags are optional and default to false. The faction with the dictionary is the acting faction and the other faction is the object faction.
The flags have the following meanings:
| Flag | Meaning |
|---|---|
"kill on sight" |
Members of the acting faction are always hostile to members of the object faction. |
"watch your back" |
Members of the acting faction will treat attacks on members of the object faction as attacks on themselves. |
"share my stuff" |
Members of the acting faction will not object if members of the object faction take items owned by the acting faction. |
"guard your stuff" |
Members of the acting faction will object if someone takes items owned by the object faction. |
"lets you in" |
Members of the acting faction will not object if a member of the object faction enters territory controlled by the acting faction. |
"defends your space" |
Members of the acting faction will become hostile if someone enters territory controlled by the object faction. |
"knows your voice" |
Members of the acting faction will not comment on speech by members of the object faction. |
So far, only "kill on sight", "knows your voice", and "watch your back" have been implemented.
