#KerbalStats KerbalStats is a KSP mod for keeping track of extra information about the kerbals in your game. It has been designed to be easily extended by other mods wishing to store kerbal specific information. Also, it is easy for mods to query KerbalStats for the stored information.

KerbalStats comes with two built-in modules that are both useful and act as sample implementations: gender and experience.

##gender module The gender module is very simple and stores only a single value representing the gender of the kerbal. It currently checks the kerbal's name for any forms that seemed to indicate a gender to the author and assigns a gender as appropriate, or should there be no obvious forms, the gender is chosen randomly.

For mods wishing to query the gender of a kerbal, the query string is simply "gender" (the module name). Any parameters will be silently ignored. The returned value is either "M" or "F" for male and female.

##experience module The experience module is rather complicated. It keeps track of the amount of game-time assigned kerbals spend doing various tasks. Along with the task, the location (planet) and situation (landed, flying, etc) of the kerbal while "performing" that task. It behaves a lot like a time-punch system. The experience module puts no meaning on the logged experience: that is up to any mods querying the kerbal's experience.

The logged task is determined by the part to which the kerbal has been assigned, or "EVA" for kerbals on EVA. For kerbals on board a vessel, the task is determined by checking a database for the part and seat in that part for the task assigned to that seat. Should the lookup fail, the task is set to "Passenger". The database is defined in seat_tasks.cfg

The tasks defined in KerbalStats are "Science", "Pilot", "Command", "Passenger" and "EVA". Other mods are free to define their own tasks and assign them to seats in parts.

This is simply a standard KSP config file. Mods wishing to define their own tasks and seat assignments need only to supply their own config file.

The config file has a root node named KSExpSeatMap with subnodes named SeatTasks. SeatTasks nodes contain only value assignments:

• name=part-name This is the part name for this SeatTasks node (eg Large_Crewed_Lab for the stock science lab).
• default=task is the task to assign should the kerbal's seat not be listed in the node (eg, the part has no IVA, or most seats have one task while a few exceptions have another task).
• seat-name=task This is the name of the seat transform as specified in the part's internal config.

For mods wishing to query the experience of a kerbal, the query string is of the form "experience:task=Pilot,body=Kerbin,situation=ORBITING". However, the parameters are optional: "experience" will return the total experience for all tasks, bodies and situtations. Also, ommitting any of the task, body or situation parameters will return the total for the ommitted qualities. eg, "experience:body=Eve" will return the total experience for all tasks and situtations in Eve's sphere of influence. The returned value is the string representation ("G17" format) of the amount of time, in seconds, the kerbal has logged for the relevant task, body and/or situation.

It is up to the mod to give actual meaning to the experience.

##Querying KerbalStats

Querying KerbalStats from a mod is very easy: include KerbalStatsWrapper.cs in your project, change ModName in the namespace to the name of your mode, and then call KerbalExt.Get() with the ProtoCrewMember object representing the kerbal and the query string.

The general format of the query string is "«module-name»:«module-params»". module-params is defined by the module.

The query always returns the value as a string, or null if something went wrong. If null is returned, then something will have been printed to the KSP logs.

KerbalStatsWrapper.cs has been writted such that there is no need to link against KerbalStats.dll. If the dll is not present, then KerbalExt.Get() will return null and log the issue.

NOTE: KerbalStatsWrapper.cs is licensed using the GNU LGPL (as is the rest of KerbalStats). This means that mods are free to use KerbalStatsWrapper.cs without worrying about their own license so long as KerbalStatsWrapper.cs itself remains under the GNU LGPL.

##Extending KerbalStats

At this stage, extending KerbalStats requires linking agaist KerbalStats.dll. To create a module, derive from IKerbalExt. It is probably best to study the gender (Gender/Gender.cs) and experience (Experience/Tracker.cs) modules to see what is needed. The gender module uses only a ConfigNode value while the experience module uses a ConfigNode node. It is then best to put the extension module in a directory that is guaranteed to come after the KerbalStats.dll (KSP dll load order issues).
