lastplayed ()
Gets how many days it has been since the player last played Naev.

Returns:

    number Number of days since the player last played.
ticksGame ()
Gets the game seconds since the program started running.

These are modified by whatever speed up the player has.

Returns:

    number The seconds since the application started running.
ticks ()
Gets the seconds since the program started running.

Useful for doing timing on Lua functions.

Returns:

    number The seconds since the application started running.
clock ()
Gets the approximate CPU processing time.

Returns:

    number Seconds elapsed since start of the process.
keyGet (keyname)
Gets a human-readable name for the key bound to a function.

Parameters:

  • keyname string Name of the keybinding to get value of. Valid values are listed in src/input.c: keybind_info.

Usage:

    bindname = naev.keyGet( "accel" )
    
keyEnable (keyname[, enable=false])
Disables or enables a specific keybinding.

Use with caution, this can make the player get stuck.

Parameters:

  • keyname string Name of the key to disable (for example "accel").
  • enable boolean Whether to enable or disable. (default false)

Usage:

    naev.keyEnable( "accel", false ) -- Disables the acceleration key
    
keyEnableAll ()
Enables all inputs.

Usage:

    naev.keyEnableAll() -- Enables all inputs
    
keyDisableAll ()
Disables all inputs.

Usage:

    naev.keyDisableAll() -- Disables all inputs
    
eventStart (evtname)
Starts an event, does not start check conditions.

Parameters:

  • evtname string Name of the event to start.

Returns:

    boolean true on success.

Usage:

    naev.eventStart( "Some Event" )
    
missionStart (misnname)
Starts a mission, does no check start conditions.

Parameters:

  • misnname string Name of the mission to start.

Returns:

  1. boolean true if mission was either accepted, or started without misn.finish() getting called in create.
  2. boolean true whether or not the mission was accepted.

Usage:

    naev.missionStart( "Some Mission" )
    
eventReload (evtname)
Reloads an event's script, providing a convenient way to test and hopefully not corrupt the game's state. Use with caution, and only during development as a way to get quicker feedback.

Parameters:

  • evtname string Name of the event to start.

Returns:

    boolean true on success.

Usage:

    naev.eventReload( "Some Event" )
    
missionReload (misnname)
Reloads a mission's script, providing a convenient way to test and hopefully not corrupt the game's state. Use with caution, and only during development as a way to get quicker feedback.

Usage:

    c = naev.cache()
    
trigger (hookname, arg)
Triggers manually a hook stack. This is run deferred (next frame). Meant mainly to be used with hook.custom, but can work with other hooks too (if you know what you are doing).

Usage:

    naev.trigger( "my_event", data ) -- data will be passed to the receiving end
    
claimTest (params[, inclusive=false])
Tests a claim of a system or strings.

Parameters:

  • params System, String or {System,String...} Table of systems/strings to claim or a single system/string.
