# playerfactions
A simple mod which allows player created factions. Not very useful on its own, it becomes very powerful when combined with other mods.
## Usage
We can choose a mode : single or multi factions.
By default the mod is single faction, if we want to change, all it takes is to add a line `mode_unique_faction = false` into the mod.conf file
Below, parameters with [] are useful only with the multi-factions mode.
There is an admin privs to enable every functions for every faction : playerfactions_admin
These commands can be used by anyone:
- `/factions create <faction> <password>`: Create a new faction
- `/factions list`: List available factions
- `/factions info <faction>`: See information on a faction
- `/factions join <faction> <password>`: Join an existing faction
- `/factions leave [faction]`: Leave your faction
These extra commands can only be used by faction owners and someone with the playerfactions_admin priv:
- `/factions kick [faction] <player>`: Kick someone from your faction
- `/factions disband [faction]`: Disband your faction
- `/factions passwd [faction] <password>`: Change your faction's password
- `/factions chown [faction] <player>`: Transfer ownership of your faction
This commands can only be used by someone with the playerfactions_admin priv:
- `/factions invite <player> <faction>`: Add player to a faction

### Using `playerfactions` in your own mod
I strongly recommend reading through the `init.lua` file; the functions at the top give you a pretty good idea of how to use it, but just in case you're short on time I'll list the most important functions below.
- `get_facts()`: Get the table with all data. The structure is :
```{["name_of_faction1"]={
["owner"]=name_of_the_owner,
["members"]={["name_of_a_member1"]=true, ["name_of_a_member2"]=true}
}}
```
- `get_player_faction(player)`: Get a string with the faction a player belongs to, `nil` if they haven't joined a faction. In multi-faction mode, it will return the oldest faction which player is into. (It checks the facts variable from the top)
- `get_player_factions(player)`: Get a table with the faction(s) a player belongs to, `nil` if they haven't joined a faction : {name_of_faction1, name_of_faction2}
- `get_owner(faction)`: Get the owner of a faction
- `chown(fname, owner)`: Change the owner of a faction
- `register_faction(faction, player, password)`: Create a new faction
- `disband_faction(faction)`: Disband a faction
- `get_password(faction)`: Gets a faction's password
- `set_password(faction, password)`: Sets a faction's password
- `join_faction(faction, player)`: Sets the given player as belonging to this faction
- `leave_faction(player)`: Clears a player's faction
Note that all of these functions have sanity checks : if faction or player does not exists, it return false. If operation succeed, it return true or the needed value.
