Module spob

This module allows you to handle the spobs from Lua.

Generally you do something like:

 p,s = spob.get() -- Get current spob and system
 if p:services()["inhabited"] > 0 then -- spob is inhabited


v = p:pos() -- Get the position
-- Do other stuff


 end

Functions

cur ()

Gets the current spob - MUST BE LANDED.

Returns:

1. Spob The spob the player is landed on.
2. System The system it is in.

Usage:

p,s = spob.cur() -- Gets current spob (assuming landed)

get (param)

Gets a spob.

Possible values of param:

- bool : Gets a random spob. <br/>
- faction : Gets random spob belonging to faction matching the number.

- string : Gets the spob by raw (untranslated) name. <br/>
- table : Gets random spob belonging to any of the factions in the
           table. <br/>

Parameters:

• param boolean, Faction, string or table See description.

Returns:

Spob The matching spob.

Usage:

• p = spob.get( "Anecu" ) -- Gets spob by name
  

• p = spob.get( faction.get( "Empire" ) ) -- Gets random Empire spob
  

• p = spob.get(true) -- Gets completely random spob
  

• p = spob.get( { faction.get("Empire"), faction.get("Dvaered") } ) --
   Random spob belonging to Empire or Dvaered
  

getS (param)

Gets a spob and its corresponding system.

Possible values of param:

- bool : Gets a random spob. <br/>
- faction : Gets random spob belonging to faction matching the number.

- string : Gets the spob by raw (untranslated) name. <br/>
- table : Gets random spob belonging to any of the factions in the
           table. <br/>

Parameters:

• param boolean, Faction, string or table See description.

Returns:

1. Spob The matching spob.
2. System The system it is in.

Usage:

• p,s = spob.get( "Anecu" ) -- Gets spob by name
  

• p,s = spob.get( faction.get( "Empire" ) ) -- Gets random Empire spob
  

• p,s = spob.get(true) -- Gets completely random spob
  

• p,s = spob.get( { faction.get("Empire"), faction.get("Dvaered") } ) --
   Random spob belonging to Empire or Dvaered
  

getLandable (param)

Gets a spob only if it's landable.

It works exactly the same as spob.get(), but it can only return landable spobs. So if the target is not landable it returns nil.

Parameters:

• param boolean, Faction, string or table See spob.get() description.

Returns:

1. Spob The matching spob, if it is landable.
2. System The system it is in.

getAll (all_spob)

Gets all the spobs.

Parameters:

• all_spob boolean Whether or not to get all Spob, including those that may not be located in a system at the time.

Returns:

{Spob,...} An ordered list of all the spobs.

system (p)

Gets the system corresponding to a spob.

Parameters:

• p Spob Spob to get system of.

Returns:

System or nil The system to which the spob belongs or nil if it has none.

__eq (p, comp)

You can use the '==' operator within Lua to compare spobs with this.

Parameters:

• p Spob Spob comparing.
• comp Spob spob to compare against.

Returns:

boolean true if both spobs are the same.

Usage:

• if p.__eq( spob.get( "Anecu" ) ) then -- Do something
  

• if p == spob.get( "Anecu" ) then -- Do something
  

name (p)

Gets the spob's translated name.

This translated name should be used for display purposes (e.g. messages). It cannot be used as an identifier for the spob; for that, use spob.nameRaw() instead.

Note that it can be overwritten by the spob's display name which makes it not equivalent to _(p:nameRaw()) in some cases.

Parameters:

• p Spob Spob to get the translated name of.

Returns:

string The translated name of the spob.

Usage:

name = p:name()

nameRaw (p)

Gets the spob's raw (untranslated) name.

This untranslated name should be used for identification purposes (e.g. can be passed to spob.get()). It should not be used directly for display purposes without manually translating it with _().

Parameters:

• p Spob Spob to get the raw name of.

Returns:

string The raw name of the spob.

Usage:

name = p:nameRaw()

population (p)

Gets the spob's population.
